The US Nuclear Regulatory Commission (NRC) requires nuclear power reactor licensees to maintain decommissioning cost estimates and to adjust those estimates periodically to account for inflation and other matters, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.75, “Reporting and Recordkeeping for Decommissioning Planning.” These periodic updates must consider various factors, including: (1) increased labor costs; (2) increased energy costs; and (3) increased waste burial costs.
