SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 64 TO FACILITY OPERATING LICENSE NO. NPF-37, AMENDMENT NO. 64 TO FACILITY OPERATING LICENSE NO. NPF-66, AMENDMENT NO. 55 TO FACILITY OPERATING LICENSE NO. NPF-72, AND AMENDMENT NO. 54 TO FACILITY OPERATING LICENSE NO. NPF-77 COMMONWEALTH EDIS0N COMPANY BYRON STATION. UNIT NOS. 1 AND 2 BRAIDWOOD STATION. UNIT NOS. 1 AND 2 DOCKET NOS. STN 50-454. STN 50-455. STN 50-456 AND STN 50-457
1.0 INTRODUCTION
On March 4,1994, the staff issued Amendment No. 58 to Facility Operating License No. NPF-37 and Amendment No. 58 to Facility Operating License No.
NPF-66 for the Byron Station, Unit Nos. I and 2, respectively, and Amendment No. 46 to Facility Operating License No. NPF-72 and Amendment No. 46 to Facility Operating License No. NPF-77 for the Braidwood Station, Unit Nos. I and 2, respectively, which approved the use of " sleeving" of steam generator tubes as an alternative to tube plugging. The amendments approved the use of either the Westinghouse laser-welded or the Babcock & Wilcox kinetically-welded techniques. The approval was documented by referencing the vendor reports in the plant technical specifications (TSs).
By letter dated July 6,1994, Commonwealth Edison Company (Comed, the j
licensee) requested license amendments which would change the TSs by referring i
to the vendor's sleeving reports generically rather than by report number and revision. The amendment request also contained an editorial change that reflects a change in the name of one of the vendors from Babcock & Wilcox Nuclear Service Company to Babcock & Wilcox Nuclear Technologies (BWNT).
2.0 EVALUATION The licensee proposed replacing references to " Westinghouse report WCAP-13698, Rev.1" with " Westinghouse Technical Report currently approved by the NRC, subject to the limitations and restrictions noted by the NRC staff"; and references to " Babcock & Wilcox Topical Report BAW-2045PA, Rev. 1" with
" Babcock & Wilcox Nuclear Technologies Technical Report currently approved by the NRC, subject to the limitations and restrictions as noted by the NRC staff."

. As the technology changes, the vendor reports will be modified and reissued, typically as new revisions. Before the newest modifications to the technologies can be used, the licensee must still formally request and receive NRC approval for the application at its specific facilities.
However, no license amendments will be required.
Because the licensee must still request and receive NRC approval prior to the application of any changes to the steam generator tube sleeving technology, the staff finds the proposed changes acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Illinois State official was notified of the proposed issuance of the amendments. The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendments change a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR-Part 20. The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure.
The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding (59 FR 39582). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.
5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
