Dear Sir or Madam:

This letter provides Attachments A through F, that were inadvertently omitted from our June 30, 2004, letter (Reference 1). By this letter, as supplemented by our May 27, 2005, letter (Reference 2) SCE requested a technical specification change to allow the deferral of the next ILRT Type A Test from the fourteenth refueling outage (scheduled for January 2006 for Unit 2 and October 2006 for Unit 3) to not later than March 30, 2010 for Unit 2 and September 9, 2010 for Unit 3 Additionally, by a separate submittal dated June 29, 2004, (Reference 3), SCE proposed a change to the technical specifications that, although it was unrelated to the integrated leak rate change, affected the same technical specification page (page 5.0-20a). In anticipation of the possibility that the technical specification change requested by the June 29, 2004 letter (Reference 3) may be approved prior to the integrated leak rate test change, this letter also includes the appropriately revised technical specification changes. Attachments G and H provide a clean copy of technical specification page 5.0-20a with both changes incorporated.

5.5.2.15 Containment Leakage Rate Testing Program A program shall be established to implement the leakage rate testing of the containment as required by 10 CFR 50.54(o) and 10 CFR 50, Appendix J, Option B, as modified by approved exemptions. This program shall be in accordance with the guidelines contained in Regulatory Guide 1.163, "Performance-Based Containment Leak-Test Program," dated September 1995.

The calculated peak containment internal pressure related to the design basis loss-of-coolant accident, Pas is 45.9 psig (Pa will conservatively be assumed to be equal to the calculated peak containment internal pressure for the design basis Main Steam Line Break (56.5 psig) for the purpose of containment testing in accordance with this Technical Specification).

The maximum allowable containment leakage rate, La, at Pas shall be 0.10% of containment air weight per day.

Leakage rate acceptance criteria are:

a. The Containment overall leakage rate acceptance criterion is s 1.0 La.

During the first unit startup following testing in accordance with this program, the leakage rate acceptance criteria are

  • 0.60 La for the Type B and Type C tests and s 0.75 La for the Type A tests;
b. Air lock testing acceptance criteria are:
1)

Overall air lock leakage rate is

  • 0.05 La when tested at 2 Pan
2)

For each door, the leakage rate is

  • 0.01 La when pressurized to 2 9.0 psig.
