If the amount of financial assurance provided by the licensee does not equal or exceed the minimum required amount of financial assurance recalculated on December 31, then the licensee must adjust the amount of financial assurance it provides, such that it meets or exceeds the required amount. Each of the methods of financial assurance should be adjustable to take into account variations in earnings and adjustments in the amount of funds being set aside for decommissioning both during operation and during storage periods, if any (see Regulatory Position C.1.4). Adjustments to the annual amount of funds being set aside may be made to coincide with rate cases considered by a licensee’s public utility commission (PUC) or by the Federal Energy Regulatory Commission (FERC). Adjustments also may be made to reflect the schedule of “ruling amounts” established by the Internal Revenue Service under Section 468A of the Internal Revenue Code for a qualified1 Nuclear Decommissioning Reserve Fund.

A licensee that may rely exclusively on an external sinking fund to provide financial assurance under the circumstances defined in 10 CFR 50.75(e)(ii)(A) or (B) (that is, where the total cost of decommissioning is provided through rates established by cost-of-service ratemaking or non-by- passable charges) may make a
