MONTICELLO NUCLEAR GENERATING PLANT (TAC NO. M94309) i i

Dear Mr. Anderson:

} As we have previously indicated to you in a letter dated September 17, 1996, the NRC will perform a confirmatory audit on the implementation of Amendment No. 97 to Facility Operating License No. DPR-22 for the Monticello Nuclear Generating Plant. The onsite audit activities are scheduled for November 14, '

1996. The agenda for the audit is enclosed for your information. The contents of this agenda was communicated to Mr. Marvin Engen of your staff on l

October 8, 1996.

1 Amendment No. 97, as approved by the NRC on September 17, 1996, modifies the 4

requirements for avoidance and protection from thermal hydraulic instabilities to be consistent with the Boiling Water Reactor (BWR) Owners Group long-term solution Option I-D described in the Licensing Topical Report NED0-31960, "BWR Owners Group Long-Term Stability Solutions Licensing Methodology," June 1991,

and NED0-31960, Supplement 1, dated March 1992. NEDO-31960 and Supplement 1 l to NED0-31960 were endorsed by the NRC staff in a letter to L.A. England (BWR

! Owners Group) dated July 12, 1993. The amendment also adds the fuel cycle

dependent stability power and flow limits in the Core Operating Limits Report.

l- The main purpose of the audit is to confirm that the station procedures, j guidelines, and training are adequate for Option I-D implementation. The j audit will be conducted by Dr. Tai Huang of this office and a NRC contractor. 3

! The results of the audit will be documented in an audit report which should be '

issued within 45_ days of the audit.
