Omaha Public Power District 1623 HARNEY E O M AH A. NEARASKA 68102 a TELEPHONE S36 4000 AREA CODE 402 January 26, 1983 LIC-83-015 Mr. Robert A. Clark, Chief U. S. Nucleat Regulatory Commission Office of Nuclear Reactor Regulation Division of Licensing Operating Reactors Brunch No. 3 Washington, D.C.

Docket No. 50-285

Dear Mr. Clark:

Fort Calhoun Station Containment Leakage Tipting Program The Commission's letter dated July 23, 1982 transmitted a Safety Evalu-ation Report (SER) regarding the District's proposed Technical Speci-fication changes to incorporate the subject Appendix J requirements.

This SER identified three open items that were subsequently addressed in

~

the District's letters dated September 3 and November 5,1982. The District stated in the November 5, 1982 letter, in response to SER open item #3, that our previous Appendix J amendment application (i.e.,

March 30, 1977) would be revised to incorporate Type C testing of penetration M-44.

Accordingly, forty (40) copies of a revised amendment application which incorporate this change, as well as several other changes, are attached.

All of the cht.nges to our March 30, 1977 appli-cation are identified in the discussion section to the attached amend-ment application. The more significant changes are detailed below:

1)

The maximum allowable leakage rate (La) will be calcult.ted using 0.2% by weight of the containment atmosphere per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at 60 psig, instead of the previous 0.1% value. This is consistent with the allowable leakage rate utilized in the District's original Final Safety Analysis Report for the maximum hypothetical accident at the Fort Calhoun Station.

Further justification is provided in the discussion section of the attached application.

2)

Reduced pressure testing of the personnel access lock (PAL) doors will be at a test pressure of 5 psig, with an acceptance criterion of less than or equal to 0.01 La, as agreed upon per a telephone conference call between the District and Commission on November 24, 1982.

Mr. Robert A. Clark LIC-83-015 Page Two Additionally, the District is requesting an exemption from the Appendix J requirement applicable to the PAL that requires testing at Pa_(if the PAL has been opened) prior to reaching a containment integrity required condition when coming out of a cold or refueling shutdown operating mode. The District proposes to leak test the PAL door seals at 5 psig prior to achieving the containment inte-grity required condition and within two weeks test the entire PAL assembly at Pa (60 psig). The District's justification for this exemption is provided in the attached.

Communications with the Commission's staff have indicated that this approach would be acceptable.

3)

Present Technical Specification (TS) Section 3.5(6) has been moved to a new TS section, Section 3.16.

TS Sections 3.5(8), 3.5(9), and 3.5(10) have.been removed from the TS because these tests were only applicable during the initial years of plant operation.

4)

Penetration M-44 has been added to the Type C testing list.

Sincerely, W. C. Jones Divis.on Manager Production Operations WCJ/TLP:jmm I
