ons in 10 CFR Part 72, as a general license ISFSI is part of the Part 50 or Part 52 site and must be decommissioned consistent with the requirements in 10 CFR 50.82 or 10 CFR 52.110, respectively. One purpose of including the decommissioning schedule in the PSDAR is to inform the NRC and the public of the anticipated timing of decommissioning events and to allow the NRC to schedule the inspection and technical review resources necessary for appropriate oversight activities. The schedule should show the relationship between the major decommissioning activities described in Section C.1 of this guide so that the reader understands the sequence and timing of the events. In addition, general decommissioning timing topics of interest that licensees could describe in the PSDAR, regardless of the decommissioning method or timeframe chosen, include the following: a. A description of the decision-making process behind the selection of SAFSTOR or DECON as the decommissioning method and the proposed timeline to decommission the facility, including the dismantlement of any components, as well as the considerations for entering SAFSTOR and an overview of the conditions under which DECON will begin at the facility, if applicable. b. A determination of the cost over time of the decommissioning strategy selected, specifically in regard to the decision to delay active dismantlement of all or parts of the deenergized components or the facility as a whole during the SAFSTOR period. c. For the DECON method, an indication of how the licensee would minimize the offsite migration of contamination and optimize worker safety, institutional knowledge, and cost in accordance with the DPR. This information may be more appropriately included in the site-specific decommissioning cost estimate that is required to accompany the PSDAR in accordance with 10 CFR 50.82(a)(4)(i) and 10 CFR 52.110(d)(1). d. If available, an estimation of the possibility of early release of parts of the site or facility
