. Docket'No. 50-412, License No. NPF-73  :

NRC' Bulletin 88-02 i

I Gentlemen: J By: lecter dated April 6, 1989 we submitted four (4) copies each of..WCAP-12141 .(proprietary version) and WCAP-12142 (non-proprietary-version) entitledL" Beaver Valley Unit 2 Evaluation for Tube Vibration Induced l Fatigue",. for NRC review and approval. These reports .

contained the following incorrect-information: 1 1

The last sentence. in the second paragraph of the j abstract 'should contain no reference to steam Generator B. The sentence should read: "This evaluation -concludes' that' two tubes in Steam Generator C are potentially susceptible to fatigue and require corrective action."

The last sentence in'Section 2.5 should reference SG-A. and SG-C, not' SG-B and SG-C. The sentence should read: "It was'found that one tube in SG-A of Beaver Valley Unit 2, and two tubes in SG-C had flow peaking values of the same order of magnitude as R9C51."

Attached are revised copies of the affected pages. The pages having " Westinghouse Proprietary Class 2" printed across the top are to. be inserted in WCAP 12141. The pages without the proprietary  ;

designation are to be inserted in WCAP 12142.
