ions, 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 reactor is less than 1200 MWt, the value of P to be used in these equations is 1200, whereas if the thermal power is greater than 3400 MWt, a value of 3400 is used for P. That is, P is never less than 1200 nor greater than 3400. The financial assurance amounts calculated in the above equations are based on January 1986 dollars. To account for inflation from 1986 to the current year, these amounts must be adjusted annually by multiplying by an escalation factor (ESC) described in 10 CFR 50.75(c)(2). This ESC is ESC (current year) = (0.65L + 0.13E + 0.22B) where L and E are the ESC from 1986 to the current year for labor and energy, respectively, and are to be taken from regional data of the U.S. Department of Labor, Bureau of Labor Statistics (Refs. 3, 4), and B is an annual ESC from 1986 to the current year for waste burial and is to be taken from the most recent revision of NUREG-1307, “Report on Waste Disposal Charges: Changes in Decommissioning Waste Disposal Costs 9 at Low-Level Waste Burial Facilities” (Ref. 5). NUREG-1307 is updated from time to time to account for disposal charge changes. In January 1986 (the base year), using disposal costs from DOE’s Hanford Reservation waste disposal site, L, E, and B all equaled unity; thus the ESC itself equaled unity. A discussion of the origin of the 0.65L, 0.13E, and 0.22B terms is given in Reference 2. Thus, MFA (in millions, current year dollars) = MFA * ESC (current year) A licensee is required by 10 CFR 50.75(f)(1) to report, on a calendar-year basis at least once every 2 years, the status of its decommissioning funding. 2.2 Cost Estimate Based on Actual Costs at Similar Facilities This type of cost estimate would be appropriate if the licensee had access to the actual costs of decommissioning a facility that
