SUPPLEMENTARY INFORMATION:
I. Introduction
The NRC is considering issuance of an exemption for license no.
DPR-73, issued to TMI-2 Solutions, LLC (TMI-2 Solutions, the licensee),
from section 70.24 of title 10 of the Code of Federal Regulations
(CFR), ``Criticality accident requirements.'' The proposed action would
exempt TMI-2 Solutions from the requirement to maintain a radiation
monitoring system in each area where licensed special nuclear material
(SNM) is handled, used, or stored that will energize clearly audible
alarm signals if accidental criticality occurs during decommissioning.
As required by 10 CFR part 51, ``Domestic Licensing of Production
and Utilization Facilities,'' the NRC prepared an EA documenting its
environmental review (ADAMS Accession No. ML23026A348). Based on the
results of the EA and the summary that follows, the NRC has determined
not to prepare an environmental impact statement (EIS) for the
exemption and is issuing a FONSI in accordance with 10 CFR 51.32
``Finding of no significant impact.''
TMI-2 Solutions requested an exemption from 10 CFR 70.24
requirements. In its exemption application, TMI-2 Solutions states that
criticality is not credible at TMI-2, and therefore it considers an
exemption to 10 CFR 70.24 for a criticality monitoring system to be
appropriate under the decommissioning licensing basis. The licensee
stated that this is because of its updated Spent Fuel Mass Limit
(SFML). Specifically, TMI-2 Solutions asserts that it arrived at this
updated SFML by taking credit for impurities and actual enrichment
based on the results of physical samples taken during the defueling
effort in 1993. In its application, TMI-2 Solutions also asserts that
administrative controls for geometric spacing are not necessary to
further preclude a criticality accident because there is not enough
Uranium Oxide (UO2) at TMI-2 to assemble an optimal critical
configuration. Regardless, TMI-2 Solutions states that, as part of its
Fuel Bearing Material Management Program, it will be implementing local
administrative controls for the purpose of defense in depth of the
activities which will handle the highest quantities of fuel bearing
material.
II. Summary of Environmental Assessment
Description of the Proposed Action
The proposed action that is being considered by the Commission is
an exemption during decommissioning from the requirements of 10 CFR
70.24 for a monitoring system capable of detecting a criticality
accident.
The proposed action is in accordance with the licensee's
application dated September 29, 2022 (ADAMS Accession No. ML22276A024).
Need for the Proposed Action
The proposed action would exempt the licensee from the requirements
of 10 CFR 70.24, which, in relevant part, requires that each licensee
authorized to possess SNM in certain quantities maintain a monitoring
system that will energize clear audible alarms if accidental
criticality occurs in each area in which SNM is handled, used, or
stored. The proposed action would also exempt the licensee from the
requirements to maintain emergency procedures for each area in which
this licensed SNM is handled, used, or stored to ensure that all
personnel withdraw to an area of safety upon the sounding of the alarm,
to familiarize personnel with the evacuation plan, and to designate
responsible individuals for determining the cause of the alarm, and to
place radiation survey instruments in accessible locations for use in
such an emergency.
Environmental Impacts of the Proposed Action
The NRC staff assessed the impacts of the proposed action on land
use; visual and scenic resources/aesthetics; climatology; meteorology;
air quality; noise; geology and soil; water; ecological resources;
historical and cultural resources; socioeconomics; transportation and
traffic; waste generation; and public and occupational health and
safety. Approval of the proposed action would not result in an
increased radiological risk to public health or the environment.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Under the No-Action Alternative, the NRC would deny the requested
action. Denying the action would have a larger environmental impact
because occupational radiation exposure would increase due to personnel
using radiation sources to calibrate criticality monitors during
decommissioning.
Alternative Use of Resources
This action does not involve the use of any resources not
previously considered in Supplement 3 to the Programmatic Environmental
Impact Statement for TMI-2, dated August 1989, NUREG-0683.
Additionally, the proposed action does not involve any environmental
resources beyond those previously considered in the exemption for the
1992 Criticality Monitoring (57 FR 26668).
Agencies and Persons Consulted
On April 4, 2023, the NRC staff consulted with Commonwealth of
Pennsylvania regarding the environmental impact of the proposed
[[Page 26612]]
action. On April 14, 2023 (ADAMS Accession No. ML23107A223), the state
official concurred with the draft environmental assessment and finding
of no significant impact.
III. Finding of No Significant Impact
On the basis of the EA referenced in Section II of this notice and
incorporated by reference in this finding, the NRC finds that the
proposed action will not have a significant environmental impact and
that preparation of EIS is not warranted. Accordingly, the NRC has
determined that a FONSI (ADAMS Accession No. ML23026A348) is
appropriate.
