Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Revision to Reactor Vessel ISI Refueling Outage Core I-II Report Gentlemen:

Attached are two revised pages of the Beaver Valley Power Station, Unit No.1 " Reactor Vessel Inservice Inspection Refueling Outage Core I-II Ret ort". This report was initially submitted to you by letter dated February 5,1981. Please remove the existing pages C-2 and C-5 fran your copy of the subject report and incorporate the attached revised pages.

Discrepancies were found on the above pages during a review of the examination requirements for IWB-2600, Items B 1.3 (Flange to Vessel Weld) and C 1.4 (Outlet Nozzle to Shell Weld). The inspection data for the abcve items should be considered as information only, new data will be used for code compliance. The new data will be otained from a re-examination of Items B 1.3 and B 1.4 which was performed during the third refueling outage.

Page C-2 has been revised to correct a typographical error. The error was found under the examination requirements of IWB-2600 Item B 1.3. In the second sentence, stud hole #3 has been revised to stud hole #13.

Page C-5 has been revised to correct the calibration block data appli-cable to " Flange to Vessel Weld". The calibration block used was CWE-RV-1 (owned by Commonwealth Edison Co.) not BVl-27 (owned by Duquesne Light Co.)

as reported under the column titled " Cal. Block Identity". The column

" Water Path Distance" revised 10" to 8". The column " Calibration" revised Hole D to Hole B. The column " Identities" revised Hole A to Hole D.

The revised pages have been side barred to identify the applicable corrections.

Very truly yours, 831004o400 830922
