NOTICE OF VIOLATION Wisconsin Electric Power Company Docket Nos. 50-266 Point Beach Units 1 and 2 and 50-301 As a result of the inspection conducted on July 22-26, 1985, 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.
Paragraph (j) of 10 CFR 50.49 requires that a record of qualification must be maintained in an auditable form to permit verification that each item is qualified for its application and meets its specified performance requirements when subjected to the conditions predicted to be present when it must perform its safety function.
Section 5.2.2 of the D0R Guidelines endorsed by paragraph (k) of 10 CFR 50.49, states that the type test is only valid for equipment identical in design and material construction to the test specimen, and any deviations should be evaluated as part of the documentation.
Section 7.0 of the Guidelines states that component maintenance or replacement schedules should include considerations of the specific aging characteristics of the component materials, and that ongoing programs should exist to ensure that equipment which is exhibiting age related degradation will be identified and replaced as necessary.
Contrary to the above, Foxboro N-E10 auxiliary feedwater flow transmitters FT-4036 and FT-4037 in both units differed in construction from the design for which the files established qualification and did not receive the maintenance defined by the files as necessary for continued qualification.
Specifically, a WEPC Nonconformance Report dated April 11, 1985, stated that required gasket replacement and cover screw torquing were not performed after a calibration. An additional Nonconformance Report dated July 22, 1985, stated that the transmitters had not been fitted with Style "B" amplifiers as necessary for qualification. As of July 26, 1985, the unqualified Unit 2 transmitters had not yet been modified.
?
In addition, until the first day of this NRC inspection, the licensee had no record of an engineering review by cognizant engineers to evaluate the consequences of the above discrepancies on the safe shutdown of the plant during an accident; nor did the licensee have evidence of a reportability review to requirements of 10 CFR 50.72 and 10 CFR 50.73 (Item 50-266/85013-02(DRS);50-301/85013-02(DRS)).
This is a Severity Level IV violation (Supplement I).

2.
Paragraph (f) of 10 CFR 50.49 requires each item of electrical equipment important to safety be qualified by testing or analysis of an identical or similar item, under identical or similar conditions. Section 2.3 (Category I) of NUREG-0588 states that the same piece of equipment must be used throughout the test sequence.
Contrary to the above, the file did not demonstrate that a single specimen of Rockbestos coaxial cable was used for the entire test sequence, nor was an analysis of the discrepancy provided in support of the qualification to NUREG-0588, Category I, claimed by WEPC (Item 50-266/85013-03(DRS);
50-301/85013-03(DRS)).
This is a Severity Level IV violation (Supplement I).
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 achidved.
Consideration may be given to extending your response time for good cause shown.
