mmissioning activities whose environmental impacts will not be so bounded and will be evaluated prior to the performance of the activities. f. The licensee fails to state how it intends to comply with 10 CFR 50.82(a)(6)(ii) or 10 CFR 52.110(f)(2) in the future, with respect to a proposed decommissioning activity identified in the PSDAR, if any unbounded environmental impacts are identified. 7. Changes to the PSDAR The regulation at 10 CFR 50.82(a)(7) or 10 CFR 52.110(g), as appropriate, requires the licensee to notify the NRC, in writing with a copy to the affected states, before it performs any decommissioning activity that could be considered inconsistent with, or making any significant schedule change from, the DG-1349 Revision 1, Page 17 planned decommissioning activities or schedules described in the PSDAR, including changes that significantly increase the decommissioning cost. Changes to the PSDAR may be in the form of a written letter to the NRC describing the change or may be an actual revision to the PSDAR. . The NRC staff will use notifications of changes to the schedule provided in the PSDAR to schedule inspections of the licensee’s activities and to provide assurance that the licensee is conducting decommissioning safely and in accordance with the applicable regulatory requirements. Examples of changes in activities and schedule include, but are not limited to, changing from long-term storage (SAFSTOR) to active dismantlement (DECON), changing the method used to remove the reactor vessel or steam generators from cutting and segmenting to intact removal, or changing the schedule to affect major milestones such as shortening the overall term to complete decommissioning. Licensees do not need to report changes related to the removal of structures, systems, or components that are not contaminated or in the immediate proximity of contaminated systems that could result in a worker dose.
