g level is desired. ! Updated site-specific estimate of remaining decommissioning costs contained in the License Termination Plan (LTP). (10 CFR 50.82(a)(9)(ii)(F)) This regulatory guide establishes a standard format for the reporting of these cost estimates that is acceptable to the NRC staff. The NRC staff suggests that licensees use this standard format to facilitate their preparation and the NRC’s review of the cost estimates. This regulatory guide supersedes the cost estimate reporting guidance provided in Regulatory Guide 1.159, “Assuring the Availability of Funds for Decommissioning Nuclear Reactors.” This regulatory guide applies only to power reactor licensees. The regulations for non-power reactor licensees are given in 10 CFR 50.82(b). The 1996 amendment to the NRC’s regulations on decommissioning procedures requires power reactor licensees that were engaged in decommissioning at the time the regulation became effective to convert to and comply with the amended regulation. All power reactor licensees are required to comply with the decommissioning procedures specified in these regulations, and no "grandfathering" considerations are applicable. The minimum decommissioning fund required by the NRC reflects only the efforts necessary to achieve termination of the Part 50 license. Other activities related to facility deactivation and site closure, including operation of the spent fuel storage pool, construction, operation, and decommissioning of an independent spent fuel storage installation (ISFSI), demolition of decontaminated structures, and site restoration activities after residual radioactivity has been removed, are not included within the NRC definition of decommissioning. Accordingly, such “non-decommissioning costs” are not addressed in this regulatory guide. Regulations applicable to the funding of spent fuel storage are in 10 CFR 50.54(bb). Regulations applicable to an ISFSI facility are in 10 CFR Part 72, “Licensing Requirements for
