Dear Mr. Grier:
On January 18, 1980, the Nuclear Regulatory Comission IE Region I was in-formed by SNUPPS of deficiencies in vertical fire dampers furnished by Ruskin Manufacturing Company to Callaway and Wolf Creek job sites. These deficien-cies were reported by telecon to Mr. Wm. Bateman of Region I pursuant to re-quirements of 10CFR50.55(e). These deficiencies are considered to be generic in nature and are judged to be applicable to all SNUPPS units.
Enclosed with this letter is a report of the defective fire dampers. This report summarizes the safety implications associated with these items, pro-vides a brief chronology of events related thereto, and indicates follow up corrective actions taken and/or planned. All fire damper units, including those on site as well as those yet to ho delivered, will be modified as indi-cated in the enclosed report and oper
, ally cycled prior to or during in-stallation.
In view of the generic r of these deficiencies the vendor, Ruskin Manufacturing Company, has bee
,ised of the need for notifying other nuclear power plant facilities, as a: apriate, and the need for follow up modification. We understand that Russin has also independently notified the NRC of this matter.
Very truly yours,
(".h-<\\C'
