0 NOTICE OF VIOLATION Detroit Edison Company .

Docket No. 50-341 Fermi 2 License No. NPF-43 As a result of the inspection conducted on March 31 to May 25,1990, and in accordance with 10 CFR Part 2. Appendix C - General Statement of Policy and Procedure for NRC Enforcement Actions (1990), the following violations were identified:

1. 10 CFR 50, Appendix B, Criterion V, " Instructions, Procedures, and I Drawings," states in part " Activities affecting quality shall be 'l prescribed by documented instructions . . . of a type appropriate to the circumstances . . . . Instructions . . . shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished."

10 CFR 50, Appendix B, Criterion VI, " Document Control," states in part " Measures shall be established to control the issuance of . . .

instructions . . which prescribe all activities affecting quality. i These measures shall assure that documents . . . are reviewed for  ;

adequacy . . . ." ,

10 CFR 50, Appendix B, Criterion X, " Inspection," states in part "A program for inspection of activities affecting quality shall be established and  :

executed . . . . Examinations . . . shall be performed for each work operation where necessary to assure quality . . . ."

10 CFR 50, Appendix B, Criterion XI, " Test Control," states in part "A test program shall be established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with  ;

written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents."

Contrary to the above, while rebuilding of the Important to Safety east mainsteam bypass valve during the fall 1989 refueling outage the licensee:

Failed to prescribe adequate documented instructions incloding the lack of appropriate quantitative or qualitative acceptar.ce criteria for determining that the east mainsteam bypass valve rebuilding effort was satisfactorily accomplished in that the instructions did not provide appropriate quantitative acceptance measurements for the length of valve stroke.

Failed to establish adequate measures for reviewing the documents associated with the rebuilding of the east mainsteam bypass valve in that the review process did not identify that it was impossible to properly rebuild the valve with the instructions provided.

i. Notice of Violation 2 Failed to. establish / execute a program for inspe: tion of the east mainsteam bypass valve in that there were no designated inspection points or work observations prescribed.

Failed to establish testing required to demonstrate that the east

, mainsteam bypass valve would perform satisfactorily in service in that no post maintenance testing was prescribed.

Thisisa'SeverityLevelIVviolation(SupplementI).

2. 10 CFR 50, Appendix B, Criterion XVI, states in part that conditions adverse to quality such as failures, malfunctions, defective material and equipment, and nonconformances are promptly identified and corrected. -

Contrary to the above, on November 23, 1989, the root cause of a condition  ;

adverse to quality was not properly determined following the identification  !

of a malfunction of the east mainsteam bypass valve during performance of a surveillance NPP-24.109.002. Consequently the reactor was operated at power with the bypass valve capable of only partially stroking.

This is a Severity Level IV violation (Supplement 1).,

Pursuant to the provisions of-10 CFR 2.201, you are required to submit to this l office within thirty days of the date of this Notice a written statement or 1 explanation in reply, including for each violation: (1) the corrective actions that have been taken and the results achieved; (2) the corrective actions that ,

will be taken to avoid further violations; and (3) the date when full compliance  ;

will be achieved. Consideration may be given to extending your response time for good cause shown.
