Dear Mr. O'Reilly:
BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 - ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL COMPONENTS - BLRD-50-438/81-66, BLRD-50-439/81 FIFTH INTERIM REPORT The subject deficiency was initially reported to NRC-0IE Inspector R. V. Celenjak on October 21, 1981 in accordance with 10 CFR 50.55(e) as NCRs BLN NEB 8113 through BLN NEB 8118. This was followed by our first interim report dated November 16, 1981. Related NCRs BLN NEB 8119 R2, and 8205 and BLN NEB 8203 R2 were reported in our second interim report dated May 10, 1982; NCRs BLN NEB 8208, 8209, 8211, 8213, 8214, and 8215, and GEN QAB 8204 were reported in our third interim report dated August 16,1982; and related NCRs BLN NEB 8217 and 8218 and BLN EEB 8203 R2, 8303, 8304, 8310 8311, 8312 8313, 8314, and 8315 were reported in our fourth interim report dated August 3,1983 Since that time, related NCRs BLN NEB 8221, BLN NEB 8302, BLN EEB 8402, BLN EEB 8405, BLN EEB 8413, BLN BLP 8328, and BLN MEB 8302 R1 'have also been reported. Enclosed is our fifth interim report. We expect to submit our next report by June 21, 1985.

FOURTH INTERIM REPORT Description of Deficiency During TVA's NUREG-0588 environmental qualification program, the components listed in Table I - Parts A and B (attached) were identified as potentially deficient because of insufficient documentation to verify that the equipment is environmentally qualified. This equipment was procured before the issuance of NUREG-0588.
Interim Progress Since TVA's fourth interim report seven additional nonconformance reports have been issued to identify potentially unqualified equipment. Information on these NCRs is included in Table 1 along with the status of other previously reported NCRs.
Corrective actions for NCR GEN QAB 8204, which was issued to identify TVA's failure to develop procedural controls on a qualification program after the issuance of NUREG-0588 and IE Bulletin 79-01B, have been completed. These actions include the issuance of computer gmerated environmental drawings and revisicns of the Division of Engineering Design (EN DES) Engineering Procedure (EP) 3 01, " Design Criteria Documents - Preparation, Review, and Approval," and applicable design criteria to reference these drawings (in the case of EP 3.01 additional references were included to provide for the proper usage of the environmental data during the accomplishment of procurement activities per EP 5.01, " Purchase Requisitions.

Limitorque This NCR identifies an interface this time proble:n between the control leads of the Limitorque valve actuators inside containment and the resistance requirements of TVA's SSCS. The Limitorque test mport on qualification to a LOCA environment listed the varying resistance of its control leads with respect to time. At various tirees (from 4.2 hrs to 95.5 hrs into the test) the resistances of the majority of the control leads decreased from 400K ohms to 2K ohns. If the insulation value of the loads fall below 20K ohms, the SSCS could interpret this decrease I
as a closed contact even though the contact itself was still open.
TVA is investigating this matter to determine which actuators could be adversely affected and will I
provide additional information in our next mport.
