NOTICE OF VIOLATION Toledo Edison Company Docket No. 50-346 As a result of the inspection conducted on July 15 through October 30, 1986, and in accordance with the General Policy and Procedure for NRC Enforcement Actions (10 CFR Part 2, Appendix C), the following violations were identified:

1. 10 CFR 50, Appendix B, Criterion III, as implemented by Toledo Edison Company (TED) Nuclear Quality Assurance Manual and Nuclear Quality Assurance Procedure, requires establishment of controls among participating design organizations for review, approval, and revision of design documents.

Contrary to the above, TED did not ensure that design was adequately controlled by engineering contractors in that: (1) the assumptions used in the purification letdown piping analysis differed from the actual system operating conditions; (2) the pressurizer relief piping analysis was not reconciled to the as-built conditions, and (3) the pressurizer relief piping analysis included apparent computer modeling errors (346/86019-06A and 06B).

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

2. 10 CFR 50, Appendix B, Criterion V, as implemented by Toledo Edison Company Nuclear Quality Assurance Manual and Nuclear Quality Assurance

- Procedure, requires activities affecting quality be prescribed by documented procedures and accomplished in accordance with documented procedures.

Contrary to the above, Bechtel procedures did not include requirements

' for combining support design loads, and the Bechtel staff did not follow approved project instructions when performing design calculation verification (346/86019-05).

This is a repetitive violation in that the Bechtel staff failed to follow procedural requirements as reported in NRC Inspection Reports No. 50-346/85035 and No. 50-346/86004.

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

3. 10 CFR 50, Appendix B, Criterion XV, as implemented by Toledo Edison Company Nuclear Quality Assurance Manual and Nuclear Quality Assurance Procedure, requires measures be established to ider.tify materials or components which do not conform to requirements for proper review and disposition.

. Noti *c3 cf Violation 2 Contrary to the above, TED did not document in nonconformance reports - Potential Condition Adverse to Quality Reports (PCAQRs) the adverse findings identified in an engineering evaluation of the PORV piping system. Three hangers did not meet the FSAR requirements, and one did not meet the IE Bulletin 79-14 interim stress allowables (346/86019-07).

This is a repetitive violation in that TED failed to document a similar nonconformance as identified in NRC Inspection Report No. 50-346/85013.

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

With respect to Item No. 1, the inspection showed that action had been taken to correct the identified violation and to prevent recurrence. Consequently, no reply to the violation is required and we have no further questions regarding this matter. With respect to Items No. 2 and No. 3, 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.
