II. Discussion

    The NRC is developing new guidance to update replacement energy 
cost estimates for both short- and long-term nuclear power plant 
outages. The new guidance document, NUREG-2242, ``Replacement Energy 
Cost Estimates for Nuclear Power Plants: 2020-2030,'' when finalized, 
updates and replaces the information contained within NUREG/CR-4012, 
Volume 4, ``Replacement Energy Costs for Nuclear Electricity-Generating 
Units in the United States: 1997-2001,'' and NUREG/CR-6080, 
``Replacement Energy, Capacity, and Reliability Costs for Permanent 
Nuclear Reactor Shutdowns'' (ADAMS Accession Nos. ML20073J435 and 
ML20076F500, respectively).
    Replacement energy costs are estimated for the U.S. electricity 
wholesale market regions with nuclear electricity-generating units over 
the 2020-2030 study period. These estimates were developed to assist 
the NRC in evaluating proposed regulatory actions that (1) require 
safety modifications that might necessitate temporary reactor outages 
and (2) reduce the potential for extended outages resulting from a 
severe reactor accident. Estimates were calculated using ASEA Brown 
Boveri's PROMOD model and ICF's Integrated Planning Model for North 
America. The model simulates dispatching a collection of generating 
units in merit order (i.e., lowest to highest incremental cost of 
dispatch) until the regional power demand is met. Each generating unit 
is characterized by the technology and fuel it uses to generate 
electricity, the unit's heat rate, and the variable and fixed costs 
incurred in owning and operating the unit. To estimate the replacement 
energy cost, the study models a Reference Case, in which all 
operational nuclear power plants are generating, and an Alternative 
Case, in which a nuclear generating unit is taken offline so that the 
next unit in merit order is dispatched to replace the lost generation. 
The difference in market clearing prices between the two cases is the 
replacement energy cost.
    The resulting wholesale power price projections capture the 
dynamics and economics of the U.S. electricity markets, which provide 
short- and long-term replacement energy cost estimates on a market area 
basis. Factors that affect replacement energy costs, such as load 
growth, replacement sources of generation, fuel prices, air emission 
requirement outlooks, and seasonal variations were treated in the 
analysis.
    On November 18, 2020, the NRC held a Category 3 public meeting 
(ADAMS Accession No. ML20336A181) to discuss the updated replacement 
energy cost estimates. The NRC appreciates feedback received from the 
November 18, 2020 public meeting and will consider comments received 
during the public comment period when developing the final NUREG-2242. 
After Commission approval and publication of the final NUREG-2242, the 
NRC plans to develop an appendix to NUREG/BR-0058, Revision 5, 
``Regulatory Analysis Guidelines of the U.S. Nuclear Regulatory 
Commission,'' (ADAMS Accession No. ML19261A278) to provide guidance for 
applying the replacement energy cost estimates.
