NUCLEAR REGULATORY COMMISSION
[NRC-2011-0060; Docket No. 50-271; License No. DPR-28]
In the Matter of Entergy Nuclear Vermont Yankee, LLC and Entergy
Nuclear Operations, Inc.; Vermont Yankee Nuclear Power Station;
Director's Decision
I. Introduction
By letters dated January 12, 2010, from Mr. Michael Mulligan,
February 8, 2010, from Mr. Raymond Shadis, and February 20, 2010, from
Mr. Thomas Saporito, these individuals (collectively ``Petitioners'')
filed separate petitions pursuant to Title 10 of the Code of Federal
Regulations (10 CFR), Section 2.206, requesting the Nuclear Regulatory
Commission (NRC or the Commission) take actions with regard to the
Vermont Yankee Nuclear Power Station (VY).
Mr. Mulligan requested in his petition that: (1) The radioactive
leak into the environment of VY be immediately stopped, VY be
immediately shut down, and all leaking paths be isolated; and (2) VY
disclose its preliminary ``root cause analysis,'' and the NRC release
its preliminary investigative report on that analysis before plant
startup.
Mr. Shadis on behalf of New England Coalition (NEC) requested in
his petition that the NRC: (1) Require VY to go into cold shutdown and
depressurize all systems in order to slow or stop the leak; (2) act
promptly to stop or mitigate the leak(s); (3) require VY to reestablish
its licensing basis by physically tracing records and reporting
physical details of all plant systems that would be within scope as
``Buried Pipes and Tanks,'' in NUREG-1801, ``Generic Aging Lessons
Learned (GALL) Report,'' and under the requirements of 10 CFR 50.54,
``Conditions of licenses''; (4) investigate and determine why Entergy
has been allowed to operate VY since 2002 without a working knowledge
of all plant systems and why the NRC's Reactor Oversight Process (ROP)
and review process for license renewal amendment did not detect this
dereliction; (5) take notice of VY's many maintenance and management
failures (from 2000-2010) and the ROP's failure to detect them early
and undertake a full diagnostic evaluation team inspection using NRC
Inspection Procedure 95003, ``Supplemental Inspection for Repetitive
Degraded Cornerstones, Multiple Degraded Cornerstones, Multiple Yellow
Inputs or One Red Input''; and (6) require VY to apply for an amendment
to its license renewal application that would address both aging
analysis and aging management of all buried piping carrying or with the
potential to carry radionuclides and/or the potential to interact with
any safety or safety-related system.
Mr. Saporito requested in his petition that the NRC: (1) Order a
cold shutdown mode of operation for VY because of leaking radioactive
tritium; and (2) issue a confirmatory order modifying the NRC-issued
license for VY so that the licensee must bring the nuclear reactor to a
cold shutdown mode of operation until the licensee can provide
definitive reasonable assurance to the NRC, under affirmation, that the
reactor will be operated in full compliance with the regulations in 10
CFR Part 50, ``Domestic Licensing of Production and Utilization
Facilities,'' and Appendix A, ``General Design Criteria for Nuclear
Power Plants,'' to 10 CFR Part 50, Criterion 60, ``Control of Releases
of Radioactive Materials to the Environment,'' and Criterion 64,
``Monitoring Radioactivity Releases,'' and other NRC regulations and
authority.
Mr. Shadis stated during a public teleconference with the PRB on
March 3, 2010, that the tritium leak is just one example of many
maintenance and management failures at VY. All three petitioners raised
a concern regarding what they perceive as the NRC's failure to examine
the deficiencies at VY in an integrated manner. This concern has met
the criteria for review in accordance with NRC's Management Directive
(MD) 8.11 ``Review Process for 10 CFR 2.206 Petitions.''
In an acknowledgment letter dated June 25, 2010, the petitioners
were informed of the PRB's decision to deny the request for an
immediate cold shutdown of VY because the PRB did not identify any
urgent safety concerns. The NRC also informed the petitioners that
their petitions were consolidated per the guidance in MD 8.11. The
consolidated petition was accepted for review for the following
specific issues and concerns stated by the petitioners in the petitions
and/or supplemented during the teleconferences:
(1) Increasing concentrations of radiocontaminants in the soil and
groundwater at VY, as well as an increasing area of contamination, are
manifest on a daily basis. VY risks aggravating the contamination by
continuing to run the reactor at full power while attempting over a
period of a month to triangulate the location of a presumed leak by
drilling a series of test wells in the affected area.
(2) During the license renewal application proceeding, the licensee
averred that it was unaware of the existence of some buried pipes, now
uncovered, and it has yet to discover their path and purpose.
(3) Entergy has, in 8 years of ownership, failed to learn and
understand VY's design, layout, and construction. This failure to
comprehend and understand the layout, function, and potentially the
interaction of the plant's own piping systems constitutes a loss of
design basis.
(4) The NRC's ROP has apparently failed to capture, anticipate, and
prevent ongoing maintenance, engineering, quality assurance, and
operation issues that have manifested themselves in a series of high-
profile incidents since Entergy took over VY. The agency has repeatedly
failed to detect root cause trends until they have, as in this
instance, become grossly self-revealing.
(5) The NRC should ensure that Entergy has adequate decommissioning
funds. The tritium leak will increase decommissioning costs because of
the need for site radiological examination and soil remediation.
Copies of the petitions are available for inspection at the
Commission's Public Document Room (PDR) at One White Flint North, Room
O1-F21, 11555 Rockville Pike (first floor), Rockville, Maryland 20852,

II. Discussion
On January 7, 2010, Entergy reported to the NRC that water samples
taken from groundwater monitoring well GZ-3 onsite at VY showed tritium
levels above background. GZ-3 is about 70 feet from the Connecticut
River. Tritium is another name for the radioactive nuclide hydrogen-3.
Tritium occurs naturally in the environment because of cosmic ray
interactions. It is also
[[Page 14998]]
produced by nuclear reactor operations, and can be legally discharged
as a radioactive effluent under NRC regulations. Tritium is chemically
identical to normal hydrogen (hydrogen-1), and, like normal hydrogen,
tends to combine with oxygen to form water, which is referred to as
tritiated water. The detection of tritiated water in the monitoring
well indicated abnormal leakage from the nuclear plant. The
Environmental Protection Agency's (EPA's) regulatory standard for
tritium in drinking water is 20,000 picocuries per liter (pCi/L).
Tritium was initially measured at levels up to about 17,000 pCi/L in
monitoring well GZ-3, which is not used for drinking water. Samples at
other monitoring wells have also shown some tritium. The highest
reading from any monitoring well has been about 2.5 million pCi/L, from
monitoring well GZ-10. Entergy immediately started an investigation to
identify the source of the tritium, and later installed additional
monitoring wells to help locate the source.
Upon notification on January 7, 2010, of the detection of tritium
in the monitoring well, the NRC's staff initiated actions to review and
assess the condition, by reviewing all available sampling data,
hydrologic information, and analyses; conducting an onsite inspection
and assessment of Entergy's plans and process for investigating the
condition; and making an independent determination of public health and
safety consequence based on available information. NRC inspectors
provided close regulatory oversight of Entergy's investigation in order
to independently assure conformance with applicable NRC regulatory
requirements, assess licensee performance, and evaluate the condition
with respect to NRC's radiological release limits.
On February 27, 2010, following excavation and leak testing of the
Advanced Off Gas (AOG) system pipe tunnel, Entergy reported that it had
identified leakage into the surrounding soil, and therefore to the
groundwater, from an unsealed joint in the concrete tunnel wall. The
AOG pipe tunnel is located about 15 feet underground. Also, piping
inside the tunnel had previously been found to be leaking, and the
drain inside the tunnel had been found to be clogged. Soil samples in
the vicinity showed traces of radioactive isotopes. Entergy reported
that the leakage to the environment had been stopped by isolating
piping and containing the water leaking from the AOG pipe tunnel.
However, on May 28, 2010, Entergy reported a second leak from AOG
piping into the soil. Entergy quickly isolated this leak and has sealed
off that piping to prevent further leaks in that area. The contaminated
soil was removed from the excavated area and is being stored in
containers onsite for eventual disposal in accordance with NRC
regulatory requirements.
As part of its oversight effort, NRC staff conducted an evaluation
in accordance with NRC Manual Chapter 0309, ``Reactive Inspection
Decision Basis for Reactors,'' from January 25 to April 10, 2010, to
determine if the occurrence with the AOG piping constituted a
significant operational event (i.e., a radiological, safeguards, or
other safety-related operational condition) that posed an actual or
potential hazard to public health and safety, property, or the
environment. The evaluation reviewed the condition against the
specified deterministic criteria that are based on regulatory safety
limits, and determined that none of the criteria were met.
Notwithstanding that determination, the NRC staff continued its review,
oversight, and assessment of the condition, including an independent
evaluation of any potential public health and safety consequences. The
staff's activities included:
1. Several onsite inspections and reviews to assess radiological
and hydrological data to establish reasonable assurance that members of
the public were not, nor were they expected to be, exposed to radiation
in excess of the dose limits for individual members of the public
specified in 10 CFR 20.1301, (i.e., 100 millirem in a year) or the As
Low As Is Reasonably Achievable (ALARA) dose objectives specified in 10
CFR Part 50, Appendix I.
2. Engagement of hydrological scientists from NRC's Office of
Nuclear Reactor Regulation, Office of Regulatory Research, and the U.S.
Geological Survey to independently assess the licensee's hydrological
and geological data and conclusions on groundwater flow characteristics
of the area.
3. Inspection in accordance with NRC Temporary Instruction TI-2515/
173, ``Review of the Implementation of the Industry Ground Water
Protection Voluntary Initiative,'' to determine the licensee's
implementation of the specifications in the industry's groundwater
initiative document NEI-07-07, ``Industry Ground Water Protection
Initiative--Final Guidance Document,'' (ADAMS Accession No.
ML072610036).
4. Confirmation of the basis, calculational methodology, and
results obtained by the licensee to estimate a contaminated groundwater
effluent release and off-site dose consequence to members of the
public.
5. Analysis of selected ground water and environmental samples to
aid in determining the adequacy of the licensee's analytical methods.
6. Approval for additional NRC inspection resources above the
baseline inspection program to fully evaluate and provide continuing
regulatory oversight of the licensee's investigation and remediation
activities.
7. Documentation of the inspection scope and conclusions in
publicly available NRC Inspection Reports.
As a result of these activities, the NRC established reasonable
assurance, in a timely manner, that this groundwater condition would
not result in any dose consequence that would jeopardize public health
and safety. To date, information and data continue to support that the
dose consequence attributable to the groundwater condition at VY
remains well below the ``As Low As Reasonably Achievable'' (ALARA) dose
objectives specified in 10 CFR Part 50, Appendix I; and that the NRC
regulatory criteria of 10 CFR 20.1301, ``Dose limits for individual
members of the public,'' was never approached.
In addition, representatives from the State of Vermont observed NRC
inspection activities and conducted independent analyses of collected
groundwater samples.
As discussed in Section I, the specific concerns raised by the
petitioners which are used as the basis for their requests are
discussed in the following paragraphs.
A. NRC Response to the Consolidated Petition
1. Concern 1--Increasing Concentrations of Radiocontaminants in the
Soil and Groundwater at VY
In order to address/remove the onsite contamination, Entergy
installed an extraction well (GZ-EW1) on March 23, 2010. On April 7,
2010, Entergy placed into service a second extraction well (GZ-EW1A),
with a higher flow capacity. As the plume progressed toward the
Connecticut River, the extraction wells were sited accordingly, with
GZ-15 being utilized for groundwater extraction at various times
starting on July 28, 2010, followed by installation of extraction well
EW-2 which began operation along with GZ-14 on September 13, 2010. As
of December 21, 2010, Entergy has pumped approximately 307,000 gallons
of groundwater out of these wells in order to reduce the amount of
tritiated water in the groundwater. About 9,000 gallons of the
extracted water was recycled to the facility, and about
[[Page 14999]]
298,000 gallons of the extracted water has been shipped off-site for
processing. Data indicates that the remaining residual plume of
tritiated groundwater is currently migrating from the source of the
leak to the Connecticut River, which is the direction of flow for the
groundwater in this location. Notwithstanding the hydrology, no
detectable tritium has been found in the Connecticut River. The NRC's
inspections to date confirm that no Federal regulatory limits have been
exceeded, and public health and safety remain unaffected.
The soil in the vicinity of the leak was contaminated with small
amounts of radioactive particulates associated with nuclear plant
operations, including manganese-54, cobalt-60, zinc-65, strontium-90,
and cesium-137. Sampling indicated very little migration in the
immediate area, which is typical for these radionuclides. Entergy has
removed about 150 cubic feet of contaminated soil and packaged it for
eventual disposal in accordance with NRC regulatory requirements.
Although some minor amounts of contaminated soil may remain, NRC
inspections indicate that this soil poses no threat to public health
and safety. Areas of remaining minor contamination are expected to be
evaluated, and as appropriate, remediated during plant decommissioning.
The NRC's experience with decommissioned nuclear plants such as Maine
Yankee, Haddam Neck, and Yankee Rowe indicates that these areas can be
successfully remediated during decommissioning. The NRC's inspections
indicate that no Federal regulatory limits have been exceeded, and
there are no health or safety concerns for members of the public or
plant workers. The initial NRC inspection covered the period of January
25 through April 14, 2010. Inspection results were initially discussed
in an NRC inspection report with preliminary results, dated April 16,
2010 (ADAMS Accession No. ML101060419). The NRC issued its completed
report on May 20, 2010 (ADAMS Accession No. ML101400040), and continued
to inspect the licensee's actions in these areas. The follow-up NRC
Inspection Report 05000271/2010010 was issued on January 7, 2011, ADAMS
Accession No. ML110070085.
As part of its corrective action program, Entergy performed a root
cause analysis (RCA) of the leakage event. The NRC assessed the
comprehensiveness of this analysis and documented this review in NRC
Inspection Report 05000271/2010009 dated October 13, 2010 (ADAMS
Accession No. ML102860037). The NRC concluded that Entergy's root and
apparent cause evaluations for the tritium ground water leakage events
were appropriate and no violation of NRC requirements was identified.
As discussed, Entergy has identified the source of the leak and
stopped it, and has reduced the onsite contamination by pumping out
contaminated groundwater and removing about 150 cubic feet of
contaminated soil. The NRC's inspections confirm that no Federal
regulatory limits have been exceeded, and the public health and safety
remains unaffected. Thus, no enforcement action is warranted for this
concern.
2. Concern 2--VY Was Unaware of the Existence of Some Buried Pipes
During License Renewal Application Proceeding
On February 24, 2010, Entergy informed the NRC that some employees
at VY had been removed from their site positions and placed on
administrative leave. Entergy took these actions as a result of
Entergy's independent internal investigation into alleged contradictory
or misleading information provided to the State of Vermont that was not
corrected. On May 27, 2010, an NRC audit team completed an onsite audit
to independently verify that information provided by Entergy material
to the renewal of the VY operating license was complete and accurate.
The NRC staff reviewed the VY yard piping drawings to independently
identify buried and underground piping located onsite. The NRC staff
performed walk-downs of yard areas and conducted interviews with the
buried piping program engineer. The NRC staff also reviewed the results
of system walk-downs previously performed by NRC inspectors during the
performance of NRC Inspection Procedure (IP) 71002, ``License Renewal
Inspection,'' as documented in NRC Inspection Report 05000271/2007006,
dated June 4, 2007 (ADAMS Accession No. ML071550330). Additionally, the
NRC staff had the opportunity to observe exposed portions of buried
piping that had been previously excavated by Entergy in conjunction
with actions taken to investigate the cause of a leak from an
underground portion of piping in the AOG system. The NRC staff compared
the results of this review to a list of buried and underground piping
Entergy had provided in preparation of the audit. The NRC staff did not
find any discrepancies between Entergy's current accounting of buried
and underground safety-related piping and the description contained in
the license renewal application, and so concluded that all information
provided to the NRC in the license renewal application was complete and
accurate in accordance with 10 CFR 50.9. Note that non-safety
underground piping is excluded from the license renewal process. The
complete audit report dated September 3, 2010, may be found under ADAMS
Accession No. ML102070412. Because the NRC staff did not identify a
violation of NRC requirements, no enforcement action is warranted for
this concern.
3. Concern 3--Entergy's Failure To Comprehend and Understand the
Layout, Function, and Potentially the Interaction of the Plant's Own
Piping Systems Constitutes a Loss of Design Basis
The design basis for VY is the information that ``identifies the
specific functions to be performed by a structure, system or component
of a facility, and the specific values or ranges of values chosen for
controlling parameters as reference bounds for design.'' The design
basis is submitted to the NRC and is approved by the NRC by issuance of
the facility operating license. Any changes to the facility as
described in the final safety analysis report (FSAR) must be either
submitted to the NRC for approval through a license amendment, or
changed in accordance with the provisions of 10 CFR 50.59. Licensees
are required under 10 CFR 50.71(e) to update the FSAR, which was
originally submitted as part of the application for the license, to
assure that the information included in the FSAR contains the latest
information developed. These submittals contain all the changes
necessary to reflect information and analyses submitted to the
Commission since the last update to the FSAR. The submittal includes
the effects of all changes made in the facility or procedures as
described in the FSAR and all safety analyses and evaluations performed
by the licensee in support of approved license amendments or in support
of conclusions that the plant design change did not require a license
amendment.
As discussed in previous Section A.2, an NRC audit team compared
the information Entergy provided in the license renewal application to
the VY Technical Specifications and the FSAR. The NRC staff determined
that the information in the FSAR would meet the requirements of 10 CFR
50.71(e) regarding maintenance of design basis information, consistent
with the definition of ``design bases'' in 10 CFR
[[Page 15000]]
50.2, and reflects current plant design. Both safety and non-safety
underground yard piping are depicted on drawings in the VY's controlled
drawings system. The staff concluded that the information reviewed was
accurate and complete and the NRC staff did not identify any loss of
the design basis. Because no violations of NRC requirements were
identified, enforcement action is not warranted for this concern.
4. Concern 4--The NRC's ROP Failure To Detect Root Cause Trends of a
Series of High-Profile Incidents
While a failure of the NRC's ROP is not something for which the NRC
could take enforcement action against VY, the NRC staff is responding
to the petitioners' concern. Objectives of the ROP include: (1)
Improving the objectivity of reactor oversight so that subjective
decisions and judgment are not central process features; (2) improving
the scrutability of reactor oversight so that NRC actions have a clear
tie to licensee performance; and (3) risk-informing reactor oversight
so that NRC and licensee resources are focused on those aspects of
performance having the greatest impact on safe plant operation.
The ROP evaluates plant performance using objective, risk-informed
thresholds, which include the safety significance of inspection
findings and performance indicators (PIs). Objective performance
thresholds are intended to help determine the level of regulatory
engagement appropriate to licensee performance in each cornerstone
area. The thresholds were established so that sufficient margin existed
between nominal performance bands to allow for licensee initiatives to
correct performance problems before they warrant escalated regulatory
involvement. Sufficient margin exists to allow for both NRC and
licensee corrective actions to be taken in response to declining
performance before plant operation becomes unsafe. Under the ROP,
performance deficiencies that have no impact on safety are considered
minor and are entered into a licensee's corrective action program for
appropriate attention, but they do not result in any specific action by
the NRC. However, the NRC reviews the licensee's corrective action
program on a routine basis while performing the baseline inspection
program, and the staff performs more in-depth reviews on a periodic
basis while performing the inspection procedure, ``Problem
Identification and Resolution.''
In addition to continuous inspection and assessment of VY
performance, annual and mid-cycle assessments of VY performance are
conducted. Annual and mid-cycle assessments involve review of the
safety significance and common factors associated with inspection
findings, and review of licensee objective performance indicators. The
results associated with the last several reviews indicate that VY is
being operated in a manner which preserves public health and safety.
The high profile events referenced by the petitioners were inspected by
a combination of specialist inspectors from both the NRC regional
office and NRC headquarters, and by the onsite resident inspector
staff. These events were determined to either not involve systems
important to plant safety, or involved performance deficiencies of very
low safety significance. In June 2009, the NRC conducted a Problem
Identification and Resolution inspection at VY. The results of this
inspection indicated that VY was generally effective in the
implementation of its corrective action program; additionally, the
safety culture of station employees, including station management,
indicated that personnel had a willingness to identify, evaluate, and
resolve plant deficiencies. The current and past performance
information, including the Mid-Cycle and Annual Assessment Letters and
inspection reports issued to VY and other licensees, are publically
available and presented on the NRC's public Web site.
The ROP Action Matrix is used to determine the level of regulatory
oversight warranted for varying levels of performance. VY is in Column
1 (Licensee Response Column) of the ROP Action Matrix because all
inspection findings and PIs at this site have very low (i.e., green)
safety significance. In accordance with Inspection Manual Chapter (IMC)
0305, ``Operating Reactor Assessment Program,'' plants in Column 1 meet
all cornerstone objectives and receive the NRC's baseline inspection
program.
The deviation process described in IMC 0305 is used to address
unique situations where the oversight defined by the ROP Action Matrix
column might not be appropriate or sufficient. Even though performance
at VY had not crossed any thresholds warranting additional regulatory
oversight, the staff considered it appropriate to apply additional
resources to monitor the licensee's efforts to address the onsite
groundwater contamination and to follow up on the licensee's response
to the NRC's Demand for Information dated March 1, 2010 (ADAMS
Accession No. ML100570237). The staff requested and received
authorization from the NRC's Executive Director for Operations (EDO) on
April 5, 2010 (ADAMS Accession No. ML100960321), to deviate from the
ROP Action Matrix to apply additional resources in these areas of
licensee performance.
Although tritium has been found in onsite monitoring wells, the
staff has not identified a hazard to public health and safety, and the
staff expects any off-site radiological releases to be very small
(i.e., off-site doses, if any, would be negligible with respect to
those received from normal background radiation levels). Nevertheless,
as noted in the Action Matrix deviation memorandum, increased NRC
oversight of the characterization, mitigation, and remediation of the
tritium contamination was warranted given the extraordinary level of
interest and concern by stakeholders. Although there is not currently,
nor is there likely to be, a public health and safety issue, the NRC is
conducting additional independent inspections and assessments of the
licensee's activities, and has increased external stakeholder
communications and outreach, to respond to stakeholder concerns and
maintain public confidence.
The NRC staff considers the ROP adequate for ensuring public health
and safety and notes that the groundwater contamination at VY does not
pose a public health or safety hazard.
The staff further notes that it has exercised its authority to
deviate from the ROP Action Matrix to be responsive to unique
circumstances and stakeholder concerns. The NRC staff conducts annual
ROP self-assessments, which include evaluations of deviations from the
Action matrix to see if improvements are warranted in the ROP. The
results of the calendar year 2010 self-assessment will be included in
the annual Commission paper and metric report, which will be issued in
early April of 2011 and discussed during the Agency Action Review
Meeting (AARM): a meeting of senior NRC managers to confirm the results
and effectiveness of the ROP. The results of the AARM will be presented
to the Commission in a public meeting in May 2011.
5. Concern 5--VY's Decommissioning Fund Is Inadequate Due to the
Increase in Decommissioning Costs
NRC establishes requirements for licensees to provide reasonable
assurance that funds will be available for the decommissioning process.
Reasonable assurance consists of a series of steps outlined in 10 CFR
50.75, ``Reporting and record keeping for decommissioning planning.''
VY must
[[Page 15001]]
file an annual report to the NRC containing a certification that
financial assurance for decommissioning will be or has been provided in
an amount which may be more, but not less than, the amount stated in
the regulations, adjusted as appropriate for changes in labor, energy,
and waste burial costs. The formula for adequate decommissioning funds
includes an estimated waste disposal volume based on the plant design.
The actual waste disposal volume may increase due to a leak or spill at
a level that requires remediation. The licensee is responsible for
payment of any increased waste disposal costs, whether paid for out of
the allocated funds from the decommissioning fund or other assets. The
current remediation of the tritium in soil and groundwater at VY has
been funded as an operating expense and no money was used from the
decommissioning trust fund. VY previously submitted a site-specific
decommissioning cost analysis, which was approved by the NRC by letter
dated February 3, 2009 (ADAMS Accession No. ML083390193). VY must
address any required changes in their next annual report. Because no
violations of NRC requirements were identified, enforcement action is
not warranted for this concern.
B. Additional NRC Actions Pertaining to Groundwater Contamination
In March of 2010, NRC's EDO established a Groundwater Task Force
(GTF) to review the NRCs approach to ground water contamination
conditions, given the recent incidents of leaking buried pipes at
commercial nuclear power plants. The charter of the Task Force was to
reevaluate the recommendations made in the Liquid Radioactive Release
Lessons Learned Task Force Final Report dated September 1, 2006 (ADAMS
Accession No. ML062650312); review the actions taken in Commission
Paper SECY-09-0174 ``Staff Progress in Evaluation of Buried Piping at
Nuclear Reactor Facilities'' (ADAMS Accession No. ML093160004); and
review the actions taken in response to recent releases of tritium into
groundwater by nuclear facilities.
The GTF completed its work in June 2010 and provided its report to
the EDO. The report characterized a variety of issues ranging from
policy issues to communications improvement opportunities. The complete
report may be found under ADAMS Accession No. ML101740509. The GTF
determined that the NRC is accomplishing its stated mission of
protecting public health, safety, and protection of the environment
through its response to groundwater leaks/spills. Within the current
regulatory structure, the NRC is correctly applying requirements and
properly characterizing the relevant issues. However, the GTF reported
that there are further observations, conclusions, and recommendations
that the NRC should consider in its oversight of groundwater
contamination incidents.
The EDO appointed a group of NRC senior executives to review the
report and consider its findings. The group reviewed the GTF final
report, including the conclusions, recommendations, and their bases.
They identified conclusions and recommendations that do not involve
policy issues, and tasked the NRC staff to address them. They have also
identified policy issues, and a policy paper has been sent to the
Commission discussing those issues.
A public workshop was held on October 4, 2010, with external
stakeholders to discuss the findings of the GTF Report and to receive
input on the potential policy issues. In addition, a request for public
comment was published in the Federal Register (75 FR 57987). These
efforts help to ensure the NRC is considering the right issues on which
to focus its attention as it moves forward. The transcript from this
meeting is available on the NRC's Web site at: http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/buried-pipes-tritium.html.
III. Conclusion
As summarized above, the NRC staff did not identify any violations
and the public health and safety remains reasonably assured. Thus, no
enforcement action against VY is warranted. The NRC staff concludes
that the petitioners' concerns have been addressed and resolved such
that no further action is needed in response to the petitions.
As provided in 10 CFR 2.206(c), a copy of this Director's Decision
will be filed with the Secretary of the Commission for the Commission
to review. As provided for by this regulation, the Decision will
constitute the final action of the Commission 25 days after the date of
the Decision unless the Commission, on its own motion, institutes a
review of the Decision within that time.
Dated at Rockville, Maryland, this 11th day of March 2011.
For the Nuclear Regulatory Commission.
