NUCLEAR REGULATORY COMMISSION
[NRC-2015-0063]
Reassessment of NRC's Dollar per Person-Rem Conversion Factor
Policy
AGENCY: Nuclear Regulatory Commission.
ACTION: NUREG; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing NUREG-
1530, Revision 1, ``Reassessment of NRC's Dollar Per Person-Rem
Conversion Factor Policy.'' This revision to NUREG-1530 updates the
dollar per person-rem conversion factor and establishes a method for
keeping this factor up-to-date. The NRC uses the dollar per person-rem
conversion factor in cost-benefit analyses to determine the monetary
valuation of the consequences associated with radiological exposure and
establishes this factor by multiplying a value of a statistical life
(VSL) coefficient by a cancer mortality risk coefficient.
DATES: NUREG-1530, Revison 1 is available on February 25, 2022.

SUPPLEMENTARY INFORMATION:
I. Discussion
Revision 1 to NUREG-1530 (ADAMS Accession No. ML22053A025) updates
the dollar per person-rem conversion factor and establishes a method
for keeping this factor up-to-date. The NRC applies the dollar per
person-rem conversion factor from NUREG-1530 in a variety of regulatory
applications that require the determination of the monetary valuation
of the consequences associated with radiological exposure. This factor
is established by multiplying a VSL coefficient by a nominal risk
coefficient.
In 2009, the NRC staff initiated research on the bases for the
determination of the VSL and performed outreach with other Federal
agencies on their values and use. The VSL is not a value placed on
human life, but a value that society would be willing to pay for
reducing health risk. The concept of a VSL is used throughout the
Federal government to monetize the health benefits of a safety
regulation. Subsequently in 2011 the magnitude of the societal effects
of the accident at the Fukushima Dai-ichi nuclear power plant in Japan
led the NRC to evaluate how its regulatory framework considers offsite
property damage and the associated economic consequences that could be
caused by a significant radiological release from an NRC-licensed
facility.
Following this evaluation, the NRC staff requested Commission
approval in SECY-12-0110, ``Consideration of Economic Consequences
within the U.S. Nuclear Regulatory Commission's Regulatory Framework,''
dated August 14, 2012 (ADAMS Package Accession No. ML12173A478) to
continue work on updating the 1995 dollar per person-rem conversion
factor in NUREG-1530 (ADAMS Accession No. ML063470485). The 1995 dollar
per person-rem value was set at $2,000. This number resulted from the
multiplication of a VSL of $3 million by a risk coefficient for
stochastic health effects of 7.3 x 10-4 per person-rem. In
the March 20, 2013 staff requirements memorandum associated with SECY-
12-0110 (ADAMS Accession No. ML13079A055), the Commission approved the
staff's request to continue the activities associated with the update
to the dollar per person-rem conversion factor policy.
This revision to NUREG-1530 makes five main changes. First, the
revision to NUREG-1530 updates the dollar per person-rem conversion
factor to $5,200 per person-rem. The value is based on the application
of an updated best estimate VSL of $9.0 million and the U.S.
Environmental Protection Agency's (EPA) cancer mortality risk
coefficient factor of 5.8 x 10-4 per person-rem. The VSL
estimate is derived from the average of both the U.S. Department of
Transportation's and the EPA's VSL in 2014 dollars.
Second, the NUREG adopts low and high dollar per person-rem
conversion factor estimates for use in sensitivity analyses. The NRC
staff recommends varying the dollar per person-rem conversion factor by
plus or minus 50 percent. This results in a range of conversion factors
with a low value of $2,600 per person-rem and a high value of $7,800
per person-rem.
Third, this revision to NUREG-1530 indicates that the NRC staff
will round to two significant figures instead of rounding to the
nearest thousand dollar value. Historically, the NRC has rounded this
number to the nearest thousand dollars for the purposes of dollar per
person-rem estimates. Given the large uncertainties inherent in this
approach, updates would have little to no impact on this value between
periodic baseline reviews.
Fourth, this revision establishes a methodology for keeping the
dollar per person-rem conversion factor up-to-date. An example of the
NRC's methodology to update the dollar per person-rem conversion factor
is provided in the NUREG. The NUREG also provides procedures for re-
baselining the dollar per person-rem conversion factor.
Finally, this revision provides guidance to the NRC staff on when
to use a higher dollar per person-rem factor in rare accident sequences
with high dose or dose rates for a portion of the population.
II. Public Outreach
The NRC staff held a Category 3 public meeting on April 2, 2015, to
discuss the update to NUREG-1530. The NRC presentation can be found in
ADAMS under Accession No. ML15086A112, and the meeting summary under
Accession No. ML15098A649. In response to this meeting, the Nuclear
Energy Institute submitted a letter to the NRC, which provided feedback
on the proposed update. This letter and the associated attachment can
be found in ADAMS under Accession Nos. ML15126A489 and ML15126A498,
respectively. The NRC staff published the draft NUREG-1530, Revision 1
in the Federal Register (80 FR 53585, September 4, 2015) for a 60-day
public comment period. The staff received 11 comment submissions with a
total of 38 individual comments from industry and members of the
public. The NRC responses to these public comments can be found in
ADAMS under Accession No. ML16147A501. External participants also
expressed views on the update to NUREG-1530 during the July 26, 2016,
Commission meeting with NRC stakeholders. Additionally, the NRC staff
briefed the Advisory Committee on Reactor Safeguards (ACRS) Regulatory
Policies and Practices Subcommittee on February 7, 2017, and the ACRS
Full Committee on March 9, 2017.
III. Backfitting, Forward Fitting, and Issue Finality
The NRC's issuance and use of this report do not constitute
backfitting as that term is defined in Section 50.109 of title 10 of
the Code of Federal Regulations (10 CFR), ``Backfitting,'' and as
described in NRC Management Directive (MD) 8.4, ``Management of
Backfitting, Forward Fitting, Issue Finality, and Information
Requests''; do not affect the issue finality of an approval under 10
CFR part 52, ``Licenses, Certifications, and Approvals for Nuclear
Power Plants'' and do not constitute forward fitting as that term is
defined and described in MD 8.4.

IV. Congressional Review Act
This NUREG is a rule as defined in the Congressional Review Act (5
U.S.C. 801-808). However, the Office of Management and Budget has not
found it to be a major rule as defined in the Congressional Review Act.
