Virgil C. Summer Nuclear Station Docket No. 50/395 Operating License No. NPF-12 Report of Status of Decommissioning Funding

Dear Sir/Madam:

The South Carolina Public Service Authority (Authority) and South Carolina Electric & Gas Company (SCE&G) have ownership interests of one-third and two-thirds, respectively, in the Virgil C. Summer Nuclear Station (VCSNS). As provided in 10 CFR § 50.75 (f)(1), each power reactor licensee is required to report to the Nuclear Regulatory Commission (NRC) on a calendar year basis, beginning March 31, 1999, and every two years thereafter, the status of its decommissioning funding for each reactor or share of reactor it owns. SCE&G has advised the Authority that it will disclose the required information relative to its two-thirds ownership share in a separate submittal.

The Authority's one-third share of the NRC formula minimum funding requirement is approximately

$149 million as of December 31, 2010. This liability is funded by payments to an external sinking fund as provided for in 10 CFR § 50.75. The escalated liability for these costs is expected to total $522 million, stated in dollars of the year of expenditure.

The market value of the external fund was approximately

$96 million as of December 31, 2010.A site-specific decommissioning study completed in 2006 identified the Authority's share of decommissioning costs which are in excess of NRC formula minimum funding requirements.

This additional liability is estimated by the Authority to be approximately

$64 million as of December 31, 2010. The escalated liability for excess costs is expected to total approximately

$285 million, stated in dollars of the year of expenditure.

The market value of the internal fund was approximately

$71 million as of December 31, 2010 and the book value was approximately

$65 million.If there are any questions concerning this report, please contact me at (843) 761-4096.Sincerely, Vice President Generation LPP:trw Attachment cc: Victor M. McCree R. E.

Escalation of the Authority's one-third share of the minimum funding requirement through the end of decommissioning.

Cost categories Labor, Equipment

& Materials, Burial, and Other were estimated in a site-specific decommissioning study. These costs were escalated through the end of the decommissioning period based on various indices and estimates.

Ultimate decommissioning costs to be funded from the external trust are estimated at $522,183,564 in escalated dollars.2.
