l%sconsin Electnc eowcacouranr 231 W. MICHIGAN, P.O. BOX 2046, MILWAUKEE, WI 53201 February 6, 1984 Mr. H. R. Denton, Director Office of Nuclear Reactor Regulation U. S. NUCLEAR REGULATORY COMMISSION Washington, D. C. 20555

Dear Mr. Denton:

DOCKET 50-266 REPEAL OF CONFIRMATORY ORDER FOR MODIFICATION OF LIs.SNSE POINT BEACH NUCLEAR PLANT, UNIT 1 During inservice inspections of the Point Beach Nuclear Plant Unit 1 steam generators performed during the August 1979 and October 1979 outages, eddy current and destructive examinations of steam generator tubes indicated intergranular attack and stress corrosion cracking originating from the secondary side of steam generator tubes within the tubesheet crevice. Although Wisconsin Electric concluded that continued safe operation of Point Beach Unit 1 was not jeopardized, additional operating conditions were proposed to provide further assurance of the continued safe operation of Unit 1 in our letters dated November 23, Noveinber 29, and December 31, 1979. These operating conditions were formally imple-mented for Point Beach Unit 1 in the NRC's Confirmatory Order for Modification of License dated November 30, 1979 and in the Order Modifying Confirmatory Order of November 30, 1979 dated January 3, 1980.

As you know, the Point Beach Unit 1 steam generator lower assemblies have bcen replaced during the current refueling and maintenance outage. The integrity and design parameters of the steam generators have been or will be verified by the performance of shop, post-installation, and return-to-service tests and inspections as outlined in the Point Beach Nilclear Plant, Unit 1, Steam Generator Repair Report, Revision 1, dated March 1983.

Since the degraded Unit 1 steam generator lower assemblies have been replaced and the integrity and performance of the repaired steam generators will be verified prior to or during the course of returning to service, the provisions of the Confirmatory Order for Modification of License dated November 30, 1979 and the Order 8402150261 840206 "

,o Mr. H. R. Denton February 6, 1984 l-Modifying Confirmatory Order of November 30, 1979 dated January 3, 1980 are no longer appropriate. In addition, those provisions from the Orders regarding reactor coolant sampling and~ primary system operating pressure have been incorporated into the plant Technical Specifications. Accordingly, there is no longer any need for these Orders, and we request that they be formally rescinded.

Very truly yours, i/
