BOX 800 2244 WALNUT GROVE AVENUE ROSEMEAD. CALIFORNIA 91770 M.O. MEDFORD TELEPHONE MANAGER, NUCLEAR LICENSING December 12, 1983 (213) 572-1749 Office of Administration Attention: Ms. Reba M. Diggs Facilities Program Coordinator License Fee Management Branch U. S. Nuclear Regulatory Commission Washington, D.C. 20555 Gentlemen:
Subject:
Docket No. 50-206 Proposed Change No. 123 San Onofre Nuclear Generating Station Unit 1 By letter dated September 9, 1983, an application for proposed Technical Specification Change Nos. 123 and 124 was submitted to the Commission. Fees pursuant to 10 CFR 170.22 were not remitted with our application based on the determination that these changes are exempt from fees because they result from independent written Commission requests for the application, clarify the Technical Specifications, and are issued for the convenience of the Commission. Your letter of November 15, 1983, has forwarded your concurrence that fees are not appropriate for Proposed Change No. 124. However, you have determined that Proposed Change No. 123 involves a single safety issue and, accordingly, a Class III fee of $4,000 is appropriate. The single safety issue involves minimizing purge and vent operations to assure that LOCA site boundary doses do not exceed the 10 CFR Part 100 limits This shall be accomplished by locking closed the manual isolation valves of the sphere purge air supply and air outlet lines during operating Modes 1, 2, 3 and 4.
Based on the information provided in your draft safety evaluation report for Generic Item B-24, it is our understanding that consideration of the single safety issue concomitant with Proposed Change No. 123 had been previously reviewed and found acceptable. In the conclusion of your evaluation you have noted your agreement that maintaining the 24-inch purge system isolation valves locked closed during plant operation in Modes 1 through 4 will preclude the release of radioactivity to the environs via the containment purge system should a LOCA occur, and therefore, the 24-inch purge system design and use are acceptable.

Ms. R. M. Diggs 2.-
December 12, 1983 Since Proposed Change No. 123 simply conforms with your request to modify the Technical Specifications consistent with the evaluation discussed above, your review will not involve additional consideration of this safety issue.
Therefore, our position continues to be that a Class III fee of $4,000 is not appropriate.
If you have any questions, please let me know.
Very truly yours, cc:
