By Order dated July 13, 2009, in PUCT Docket No. 36796, Constellation South Texas was granted approval to establish a separate subaccount for the pre-shutdown disposal of large components. By Order dated October 7, 2013, in PUCT Docket No. 41580, Constellation South Texas was granted approval to establish a separate subaccount for amounts recovered pursuant to a litigation settlement agreement with the United States government for certain onsite spent fuel storage and management expenses it has incurred and will incur as a result of the failure of the Department of Energy to provide for the offsite disposal of spent nuclear fuel. The amounts allocable to the subaccounts are not included in the reported amount and have been exclusively funded by Texas ratepayers. The reported amount includes funds accumulated based upon a site-specific study that includes license termination and other costs.

The NRC formulas in section 10CFR50.75(c) include only those decommissioning costs incurred by licensees to remove a facility or site safely from service and reduce residual radioactivity to levels that permit: (1) release of the property for unrestricted use and termination of the license; or (2) release of the property under restricted conditions and termination of the license. The cost of dismantling or demolishing non-radiological systems and structures is not included in the NRC decommissioning cost estimates. The costs of managing and storing spent fuel on site until transfer to DOE are not included in the cost formulas.

2.

By Order dated November 20, 2008, in PUCT Docket No. 35786, CPS Energy was granted approval to establish separate spent fuel management and pre-shutdown activities subaccounts. The amounts allocable to these subaccounts are not included in the reported amount. The reported amount includes funds accumulated based upon a site-specific study that includes license termination and other costs.

3.

CPS Energy estimates that the Trust is currently fully funded, based on the 2023 decommissioning cost study and updated escalation rates. Additional contributions ended December 31, 2008. If future estimates indicate that further funding may be required, CPS Energy would be able to apply to the PUCT to seek further funding for NRC license termination costs through cost-of-service recovery authorized by Texas law.
