Subject:

Virgil C. Summer Nuclear Station Docket No. 50/395 Operating License No. NPF-12 Reactor Vessel Fluence -and Reactor Temperature Pressurized Thermal Shock Rule (RTpts) Evaluation

Dear Mr. Denton:

Enclosed are copies of the WCAP-10998 '(Dec. 85/ Revision 1), " Virgil C. Summer Nuclear Station Unit 1 Reactor Vessel Fluence and RTpts Evaluation".- This report satisfies the requirement that current and projected values of RTpts for reactor. vessel- beltline region materials be evaluated and reported to the NRC.

RTpts values contained in this report are based on actual plate and weld material chemistry data and are well below the NRC screening criteria values for pressurized thermal shock. The actual and projected neutron fluence levels were used through both the present and proposed operating . license expiration dates (i.e. 26.5 and 35.1 effective full power years, respectively).

If you should have any additional questions, please advise.

Very truly, yours, 1
