SUBJECT:

RESPONSE TO GENERIC LETTER 89-08, " EROSION / CORROSION-INDUCED PIPE WALL THINNING'l (TAC NO. 73486)

On May 2,.1989, the Commission issued Generic Letter (GL) 89-08 dealing with

' pipe wall thinning. induced by erosion / corrosion. In this. letter, we requested the implementation of a:long-term erosion / corrosion monitoring program that will provide assurance that procedure or administrative controls are in place to

~

assure that the NUMARC program or another equally effective program is implemented to assure the structural integrity of all high energy carbon steel systems.

By letter dated' July.20, 1989,'you responded to our GL for the Fort Calhoun Station by describing the program in progress, the Administrative Controls and procedures, the NUMARC and EPRI programs that have been or will be implemented, i and the engineering' activities performed and updated to provide an adequate response.to GL 89-08. Your response provides assurance that erosion / corrosion will not degrade the pressure boundary to below the applicable code-design value. This fulfills your requirements in responding to GL 89-08. You should maintain, in auditable form, records of your program and the results of your implementation of the program. These records may be subject to future auditing.

'.This completes our effort under TAC No. 73486.
