Letter, J.

B.

Hickman (NRC) to E.

E. Fitzpatrick (I&M), April 15, 1994.

The referenced letter transmitted NRC acceptance of our responses to NRC Bulletin 88-02, entitled "Rapidly Propagating Fatigue Cracks in Steam Generator Tubes".

The letter requested that we

1) inform the NRC when we have removed steam generator tube R8C35 from service, and 2) establish administrative controls to ensure that updated stress ratio and fatigue usage calculations are performed in the event of any significant changes to the steam generator operating parameters, or inform the NRC if administrative 'controls will not be established.

Steam generator tube R8C35 was removed from service during the Unit 1

Cycle 13-14 refueling outage.

Also, administrative controls have been established as requested.

Sincerely, E.

E. Fitzpatrick Vice President aj f i:Lnsllletterl1056f.msa 9407060158 940628 PDR ADONAI'5000315 PDf.
