the following violations were identified.

A.

Technical Specification 3.9. A.4.e requires that prior to startup from a cold condition the undervoltage (UV) relays shall be operable on start buses IA and 13.

Contrary to the above, the requirement that the UV relays be operable prior to startup fran a cold condition was not met in that on August 15, 1981, Unit 2 was started up and operated at power with one UV relay being inoperable. This condition was identified by the licensee on August 19, 1981.

This is a Severity Level IV Violation (Supplement I.D.2.) and is applicable to Unit 2.

B.

Technical Specification 3.1 requires that a minimum of instrument channels must be operable as given in Table 3.1.A.

The table requires that 2 average power range monitor (APRI) channels per trip system be operable for high flux protection during reactor power operation.

Contrary to the above, from 9:30 p.m. on July 8,1981 until 10:30 a.m. on July 9,1981, the APRi channels were not operable as required in Table 3.1.

The operation - maintenance instructions and parts catalog for the hydrogen - oxygen (H2-02) sample and return solenoid valves requires the licensee to adequately seal the conduit connections to the solenoid to prevent entrance of moisture inorder to maintain IEEE 323 qualifications.

Contrary to the above, the design bases for the H2-02 system was not met in that on July 31, 1981, the licensee determined that the sample and return solenoid valves for the H2-02 monitoring system in Unit 3 torus were not 8111130604 011106 PDR ADOCK 05000259 G
