SUBJECT:

TECHNICAL SPECIFICATIONS FOR DIABLO CANYON UNIT 2 i

The MEB during the review of the Diablo Canyon Unit 1 Inservice Testing Prcgram for Pumps and Valves identified certain check valves in the Safety Injection System and the Residual Heat Removal System that should be tested in accordance with Technical Specification 4.4.6.2.2 and lt included in Table 3.4-1 of the Technical Specifications. These check

,il valves are:

J'.

Safety Injection System (SI) 8905A SI to hot leg - 1, 8905B SI to hot leg - 2 890:iC SI to hot leg - 3, and 8905D SI to hot leg - 4.

1 Residual Heat Removal System (RHR) 8740A RHP to hot leg - 1, and 8740B RHR to hot leg - 2.

The Unit 2 Technical Specifications should also be revised to incorporate the check valves identified above.
