1 - DOCKET NO.50-000 INTEGRATED LEAKAGERATE TESTING

Dear Mr. Denton:

Carolina Power 2 Light Company (CP(t(L) willperform Integrated Leakage Rate Testing (ILRT) on the Shearon Harris Nuclear Power Plant approximately two weeks after the completion of Hot Functional Testing (HFT). We request your concurrence to perform a reduced duration peak pressure ILRT to satisfy the requirements of-10 CFR 50, Appendix 3. 3ustification for this test is discussed in Bechtel Topical Report BN-TOP-I, "Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants, Rev. 1." The containment atmosphere stabilization criteria of Section 2.3.A of BN-TOP-1 willbe used.

To determine the duration of the ILRT, the criteria discussed in Section 2.3 of BN-TOP-I willbe used with the following exception:

The end of test upper 9596 confidence limit for both the least squares fit calculated leak rate based on Total Time calculations and the least squares fit based on mass-point calculations, plus penalty leakages, shall be less than 0.75 La.

To support our current schedule for HFT and ILRT, we request your concurrance with the test method outlined above by 3anuary 15, 1986. If you have any questions concerning this subject or require additional information, please contact me.

Yours very truly, SRZ/GAS/crs (3125GAS)
