SUBJECT:

AMENDMENT 26 TO GE LICENSING TOPICAL REPORT NEDE-2401 1-P-A, "GESTAR I'"- IMPLEMENTING IMPROVED GE STEADY-STATE METHODS (TAC NO. MA6481)

Dear Mr. Watford:

By letter dated October 22, 1999, General Electric Nuclear Energy (GENE), submitted a request for review of Amendment 26 to GESTAR as a standard amendment. GESTAR Amendment 26 was submitted by letter dated August 13, 1999, as an administrative change, and involved three areas. These areas were: (1) clarifying classification of BWR 6 pressure regulator failure downscale event; (2) implementing improved General Electric (GE) steady-state methods; and (3) incorporation of Boiling Water Reactor Owners Group (BWOG) approved stability options.

This submittal was later supplemented by letters of September 17 and October 14, 1999. The NRC staff has reviewed Item 2 of the submittal, in relation to the GE improved steady-state methods, and has prepared the enclosed safety evaluation. We find Item 2 of the proposed Amendment 26 is acceptable, as discussed in the safety evaluation. Items 1 and 3 will be addressed under a separate cover letter.

Sincerely, Original Signed By:
