AL=1,>'1 Outside of Scope AFW Piping Degradation Buried AFW piping to the 12 and 14 S/Gs appears to have significant degradation of the protective coating and piping.

The preliminary guided wave inspection results indicate that the ASME Class 2 piping is degraded below min wall.

The pipe is schedule 80 4" inside diameter carbon steel piping with a coal tar type coating that appears to been hand applied. The piping run of concern involves about 150 ft of pipe that is buried at depths ranging from 4 ft adjacent to the out side of containment to 17 ft deep in a covered area adjacent to the containment

'The UT resul 4 ts confirmredthe tguided wave resuilts. Engineering deter mined the ycould not support operability of I the piping through the next cycle. PSEG is pla~nning to replace thie shallow sectioni of affected piping~and periformling further evaluations of the deeppingwithIacontingency to replace if needed. Enginee ring evaluatinogaboveor below ground installation and expects a decisi*n on 4/9/10. Piping repairs scheduled for completion on 4/25.

.IS code gives more allowance to an operating unit (they can take credit for up to 90% of the yield stress). DRS has provided access to the information and will review. FPSEG is currently evaluating n~eed for inspections of the piping ~at Unit 2 and expects a decision to be made by Monday (4/12). On eaqh unit there arethreesafety-related systems with. buried piping (ASW, S.W.
