Licensees that plan to begin major decommissioning activities shortly after permanent cessation of operations should consider an early submission of the site-specific decommissioning cost estimate with the PSDAR. If the licensee’s PSDAR specifies a delayed completion of decommissioning, the licensee must provide a means of adjusting cost estimates and associated funding levels over the storage or surveillance period to ensure that the appropriate amount of funding will be available to terminate the license (10 CFR 50.82(a)(8)(iv) and 10 CFR 52.110(h)(4)).

If a licensee believes that the NRC is using this regulatory guide in a manner inconsistent with the discussion in this Implementation section, then the licensee may file a backfitting or
