Gentlemen:
DOCKET NOS. 50-266 AND 50-301 ADDITI0ftAL IllFORMATION IE BULLETIN 80-11, MASONRY WALLS POINT BEACH flUCLEAR PLANT, UNITS 1 AtlD 2 On June 9-11, 1981, members of your Staff met with Wisconsin Electric and our consultants at the Point Beach Nuclear Plant to conduct I
an onsite review and audit of our responses to IE Bulletin No. 80-11.
Discussions were held during this meeting to resolve differences between the flRC Staff's design criteria and the criteria used by Wisconsin Electric in evaluating the Point Beach masonry walls. The result of these discussions was the formulation of 21 action items which, when complete, would resolve the NRC's concerns regarding the analysis of masonry walls at the Point Beach Nuclear Plant. These action items were formally transmitted to us with Mr. Colburn's summary of meeting minutes dated July 1,1981.
Our letter of September 15, 1981 transmitt:. responses to action items 5, 7, 9,11, and 16 of fir. r Cburn's summary.
Resgases to action items 1, 4, and 6 were not yet complete. The enclosures to this letter provide our responses to these remaining items, as well as revisions to our responses to action item Nos. t and 11. Also included are additional copies of our July 15, 1981 responses, as requested by Mr. Colburn.
Please contact us if you have any questions regarding this information.
Very truly yours, l'f'j(
