Dear Mr. Hukill:

SUBJECT:

ENVIRONMENTAL QUALIFICATION OF ELECTRICAL EQUIPMENT IMPORTANT TO j SAFETY - EXTENSION OF DEADLINE Section 50.49(g) of 10 CFR Part 50 requires that each holder of an operating j license issued prior to February 22, 1983, shall by May 20, 1983, identify ,

 ,j             the electrical equipment important to safety within the scope of this section i             already qualified and submit a schedule for either the qualification to the i             provisions of this section or for the replacement of the remaining electrical equipment important to safety within the scope of this section. This schedule must establish a goal of final environmental qualification of the
  ;             electrical equipment within the scope of this section by the end of the i             second refueling outage after March 31, 1982, or by March 31, 1985, whichever is earlier. The rule also provides that the Director of the Office of
]j              Nuclear Reactor Regulation may grant requests for extens hn of this deadline to a date no later than November 30, 1985, for specific pieces of equipment
 .l             if these requests are filed on a timely basis and demonstrate good cause for 4             such an extension, such as procurement lead time, task complications and
               ' installation problems.         In addition,10 CFR 50.49(h) provides that each licensee shall notify the Connission of any significant equipment problem

• that may reoufre extension of the completion date provided in paragraph (g) of this section within sixty days of its discovery.

As required by 10 CFR 50.59(g), you provided a submittal dated May 20, 1983 ,! which stated that no extension would be needed to the March 31, 1985 deadline

  ;             for environmental qualification of electrical equipment. However, the staff c1              was unable to concur in you position and by letter dated May 25, 1984,
'j              requested additional information. After further NRC staff review, audits and d               discussions with your staff, your submittal dated December 11, 1984                       ;
  .             identified nine (9) items of equipment that were not qualified. Subsequently,              -

seven (7) of these items were qualified by replacement or. testing, leaving two i items which could not be qualified by the March 31, 1985 deadline. Your

  ;             schedular extension request dated February 12, 1985 was supplemented by additional explanation of your JI0s for these two items dated March 25, 1985.

The two items are discussed below, i o

9 .. _ . _ _ _ ._ f i Henry D. Hukill l The incore thermocouple extension cable and connector provides core outlet temperature from 52 locations in the outlet plenum of the fuel assemblies. ' You believe that the cables / connectors can be shown to be qualified and i tests are underway for this purpose. If the cables / connectors fail the qualification tests, the cables / connectors will be replaced with qualified cable. The tests are scheduled to be completed in May 1985 and concurrent procurement of qualified replacement cable / connectors is expected to take up to 30 weeks. -In the interim, alternate cualified instrumentation is ~. available. 1 The high range radiation monitoring instrument is qualified but the cable 'j and connector assembly from the two Victoreen detectors located inside containment to the containment penetration has not been demonstrated to be fully qualified. The cable and connector assembly is to be replaced by qualified equipment which has been ordered and is scheduled to be delivered l within about 15 weeks. In the interim, the existing dome monitor will be

;         available for immediate post-accident monitoring based on TMI-2 experience, i        and the containment atmosphere post accident sampling system will be available for the longer term monitoring.                                       -

i We have reviewed the submittals of February 12 and March 25, 1985 and conclude that the requests for extension is timely and within the scope of 10 CFR 50.49(g) and that the licensee has shown good cause for the extension. We have reviewed the JI0s and conclude that they are sufficient to support i operation during the recuested extension period. 1 i We also find that extending the implementation date until November 30, 1985 is acceptable and that operation until that time will not adversely affect j the public health and safety. f Your request for a schedular extension under 10 CFR 50.49 is hereby granted.
