RE: JAMES A. FITZPATRICK NUCLEAR POWER PLANT Q
Dear Mr. Berry:
b
.N'
/ %, i t i co On July 2,1981, we sent a letter to all licensees who itave requested approval to operate on a continuing basis at power levels above 50!, with only one recirculation loop in the event the other loop is inoperative. You and other BWR licensees received a copy of one of these letters since we expect most BWR facilities would like to have this flexibility.
In the letter we proposed a meeting to obtain a better understanding of what might have caused variations in jet pu p flow and related parameters at Browns Ferry Unit No.1 during single loop operation and how this incident should affect approval of single loop operation at other facilities.
You have indicated to your NP.C project nanager that you are interested in attending the proposed meeting. The reeting will be held at 9:00 A.M.,
Vednesday, Septenher 9,1981 in roon P-118, Phillips Building, 7920 Norfolk Avenue, Bethesda, "aryland. You are requested to advise your project ranager of the people who will be attending this reeting from your organization.
Sincerely, o%inal Sfsned by I A Ippolito Thomas A. Ippolito, Chief Operating Reactors Branch #2 Division of Licensing Enclosure-f'eeting Agenda cc w/ enclosure See next page Distribution:

Proposed Meeting with BUR Applicants and Licensees'en Single Leop Operation Purpose of Meeting:
1.
To determine What may have caused the jet pump flow and other variations experienced by Browns Ferry Unit 1 during single loop operaticn and 2.
Evaluate whether the Browns Ferry experience should result in power limits for other BWRs operating on a single loop.
Agenda:
1.
Discussion of what may have caused the unexpected variations in operating parameters when Browns Ferry Unit 1 exceeded about 60 percent rated power while operating with only one recirculation inco.
2.
Discussion of parameters affected at Browns Ferry 1 (i.e., jet pump flow, neutron flux, core ficw, core pressuredrop,etc.)
3.
Discussion of whether the Browns Ferry 1 experience would be expected at other BWRs operating on one recirculation loop.
If so3_are safety limits likely.to be violated or cause complications with respect to core stability, core flow symmetry, pump cavitation or damage to the jet pumps and reactor vessel internals.
4.
Discussion of the benefits vs. potential problems and cost of testing single loop operation in another BWR that is instrumented to detect what parameters are affected.
5.
' Evaluation of whether single loop operation at p5wer levels about 50 to 55 percent is a safe and prudent means of reactor operation.
