EFFECTIVE FROBLEM SOLVING April 11. 1983 NUCLEAR OPERATIONS DikECTIVE Wo.21 EFFECTIVE PROBLEN SOLVING FURPOSE The purpose of this directive is to assure that the cause of a problem is accurately determined and properly resolved prior to continuing a safety-related activity.

-CENERAL It is fundas.;.tal to identify a problem before working on its solution.

(Detroit Edison provides supervisors and management personnel with training

, in the use of Kepner-Tregoe problem solving techniques.)

After an incident or apparent problem occurs, no safety-related activity should be resumed until the problem has been identified, its cause deter-ained and a solution formulated and implemented. (Example: In the case of a plant trip, the reason for the trip sust be determined by careful analy-sis of the data. After the probles has been identified, its solution should be formulated and implemented. Startup must be properly authorized before the reactor la again started.)

It is vital that this directive be followed to the fullest extent.

Dear !*r. Tauber:

Subje-t: Use of SN-TOP-1 for the Fermi-2 Facility Containment Leakage Testing Per Appendix J Pe have reviewed your letter dated August 18, 1983, in which you stated your adoption of a minimum test duration of eight hours for the Type A conteinnent integrated leak rate test to be performed at the Fermi-2 facility in accordance with Appendix J.to 10 CFR Part 50. Your basis for this abbreviated test duration is the acceptance by the NRC of the Eechtel Tcpical Report, SN-TOP-1, " Testing Criteria for Integrated Leakage Eate Testing of Primary Containment Structures for Nuclear Plants," Revision 1.

However, before we will accept your proposal for an eight hour Type A test duration, we require you to commit to adopt all applicable provisions in the cited topical report associated with an eight hour type A test duration. ,

Specifically, your Technical Specifications should include either an identical or a rore conservative set of test rethods, acceptance criteria and instrunentation relative to those cited in BN-TOP-1. We anticipate seeing these items incorporated into ycur Technical Specifications. If they are not, we will include these items in the Tech Specs during the " proof and review" stage. If you have any ouestion on this matter, please contact the Project Manager, M. D t vnch, ,

at 301/492-7050.

Sincerely,

g4 4 B .f Joungbl od, Chief Lic #ing Branch No. 1 DivisioncfLicensing cc
