NOTICE OF VIOLATION Toledo Edison Cenpany Docket No. 50-346 As a result of the inspection conducted on January 14 through April 2, 1986, and in accordance with the " General Policy and Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985), the following violations were identified:

1. 10 CFR 50, Appendix B, Criterion V, as implemented by Toledo Edison Company Nuclear Quality Assurance Manual and Nuclear Quality Assurance Procedures, requires activities affecting quality be accomplished in accordance with documented procedures.

Contrary to the above:

a. The Bechtel Associates Professional Corporation (Bechtel) engineering staff failed to report to Toledo Edison Company, as required by Bechtel Procedure MGP-04 Paragraphs 6.1.a and 6.1.b.

that based on stress calculations performed during December 1985 and January 1986, several piping systems and supports did not meet FSAR conditions. Consequently, Toledo Edison could not evaluate, for reportability to the NRC, the impact of the deviations on system operability. This is a repetitive finding (Reference Inspection Report No. 50-346/85035).

b. From 1976 to 1979 there were 46 PORV lifts for which the loop seal temperature was assumed to be 130 F. This violated the acceptance criteria specified in site Procedure PT 5164.03 which limits the number of PORV lifts to 25 times if the loop seal temperature drops below 400 F.

This is a Severity Level IV violation (Supplement II).

2. 10 CFR Part 50, Appendix B, Criterion XVI, as implemented by Toledo Edison Company Nuclear Quality Assurance Manual and Nuclear Quality Assurance Procedures, requires that measures be established to assure that conditions adverse to quality such as deficiencies, deviations, defective material and equipment, and nonconformances, are promptly identified and corrected. In the case of a significant condition adverse to quality, the measures must assure that the cause of the condition is determined and that corrective action is taken to preclude repetition.

Engineering Services Technical Report (TES) TR-5639-2, " Davis-Besse Analysis and Evaluation of the Safety / Relief Valve Discharge System per NRC NUREG-0737," Revision 0, dated January 1983 specifies that the heat trace temperature for the pilot operated relief valve (PORV) loop seal be maintained at 500 F.

Notice of Violation 2 Contrary to the above, site Procedure PT 5164.03 was not revised to reflect the 500*F temperature specified in TES TR-5639-2 and no attempt was made to inspect and evaluate the condition of the piping and supports.

This is a Severity Level IV violation (Supplement li).

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