The letter described the Induction Heating Stress Improvement program initiated to augment the Supply System position.

The IHSI program has been completed.

The final program summary is as follows:

o Originally 204.welds in the Reactor Recirculation (RRC) and Residual Heat Removal (RHR}'ystems, were identified for review.

On completion, 214 welds (including 10 RPV discharge nozzle to safe end welds not originally reported) were reviewed.

o Thirty-eight (38} welds.were originally found to be properly treated for protection from IGSCC and classified as conforming.

On completion, a

total of, 50,.welds were classified as conforming.

(Ten RPV discharge nozzle to safe end welds not originally reported were classified as conforming, plus 2 welds originally considered non-conforming were reevalua'ted and..reclassified as conforming.)
