i%sconsin Electnc rom coww 231 W. MICHIGAN, P.O. BOX 2046. MILWAUKEE, WI $3201 November 14, 1984 Mr. H. R. Denton, Director Office of Nuclear Reactor Regulation U. S. NUCLEAR REGULATORY COMMISSION Washington, D. C.
20555 Attention:
Mr. J. R. Miller, Chief Operating Reactors, Branch 3 Gentlemen:
DOCKET NO. 50-301 ENVIRONMENTAL QUALIFICATION OF FEEDWATER REGULATING BYPASS VALVES POINT BEACH NUCLEAR PLANT, UNIT 2 This letter will inform you of the current status of the environmental qualification upgrade program for the feedwater regulating bypacs valves at our Point Beach Nuclear Plant, Unit 2.
This letter also requests a time extension for completion of the environmental qualification deadline to 30 days after acceptable receipt of materials for the feedwater regulating bypass valves.
The current deadline was November 1, 1984.
Environmental upgrading of the feedwater regulating bypass valves has been completed except for replacing solenoid-operated air valve 2-SV481.
This valve has not been replaced due to vendor supply problems which have delayed shipment of the replacement valve.
Upon receipt of the necessary material, we will complete this upgrade.
We have evaluated startup and operation of Unit 2 without this work being complete and determined that such operation will impose no undue risk to public health and safety.
This conclusion is based on the fail-safe basis of the system, i.e.,
failure of.the solenoid valve will cause the feedwater regulating bypass valve to shut as required.
Replacement of the solenoid valve can be accomplished during power operations as the feedwater regulating bypass valves are normally closed at power levels above 15%.
Since the bypass valve is in the position during normal operation that is required following safeguards actuation, there is no risk in replacing the solenoid valve. %

'We,;therefore,. request that the environmental qualification Jdeadline for the Point Beach Unit 2 feedwater regulating bypass.
valves be extended-to 30-days after acceptable receipt of materials.
'We believe that thistextension is appropriate in-that we were a
. unable to complete-this-work'because of conditions outside our.
' control,'namely vendor supply problems.t We believe 'that this 1
-request is. supported by good cause in that.as much work as is possible' has been completed ::Ln order' to meet the intent of-the environmental qualification rule and1 operation without this qualified ^
. solenoid valve will not be detrimentalsto plant safety.
We would be pleased to~ answer any questions you may have.regarding'this,information;orithis request-for. extension of the environmental.,._ qualification deadll'ne; Very truly yours, Vice President-Nuclear Power C. W. Fay Copy to NRC Resident Inspector i
