estimate of costs if desired; however, the cost of radiological decommissioning (as decommissioning is defined by 10 CFR 50.2) should be listed separately. As a separate item, the cost of placing and maintaining the facility in safe storage should be identified, along with a plan to assure that sufficient funds will be available for this purpose, if necessary, until such time as the radioactively contaminated material is placed in an authorized waste disposal site. It should be noted that, as with the PSDAR, 10 CFR 50.82(a)(8)(iii) requires a licensee to provide a site-specific decommissioning cost estimate within two years following permanent cessation of operations. If the estimate of costs provided with the PSDAR is a site-specific cost estimate, this requirement can be satisfied with the PSDAR submittal. This regulatory guide pertains only to preparation of the cost estimate portion of the PSDAR. Guidance on preparation of all sections of the PSDAR will be found in Regulatory Guide 1.185 (Ref. 2). 2.1 Cost Estimate Based on Financial Assurance Amounts (10 CFR 50.75(b) and (c)) Licensees of operating nuclear power reactors must provide reasonable assurance that funds will be available to accomplish decommissioning within 60 years from the date of permanent cessation of operations, as required by 10 CFR 50.82(a)(3). Reasonable assurance may be demonstrated by compliance with the requirements of 10 CFR 50.75(b), (c), (e), and (f). These requirements ensure that a licensee has financial assurance in effect for an amount that may be more but not less than the amount stated in the table in 10 CFR 50.75(c)(1). Specifically, this table says that if P equals the thermal power of a reactor in megawatts (MWt), the minimum financial assurance (MFA) funding amount (in millions, January 1986 dollars) is: For a pressurized water reactor (PWR): MFA = (75 + 0.0088P) For a boiling water reactor (BWR): MFA = (104 + 0.009P) For either a PWR or BWR, if the thermal power of the
