J. Rausch letter to J. G. Keppler dated December 29, 1981-
Dear Mr. Keppler:
The Commonwealth Edison Company review conducted in accordance with the subject bulletin disclosed that eight (8) of the i
suspect valcor Engineering Corporation solenoid valves have been supplied as solenoid operators on Anchor / Darling valves at Byron and Braidwood Stations (4 per station).
These solenoid valves are not i
subjected to high temperatures, therefore we do not expect to encounter the problem described in the bulletin.
It is our intent-to replace the coils in these solenoids-with new coils supplied by valcor.
Replacement will be completed
~
l prior to-commencing operation (the current schedule is to have-replacement completed by April 16,-1981).
I Approximately 18 man-hours were e'xpended in conduct of the l
review and preparation of this report.
The manpower required to j
replace the coils is estimated to be a total of 20 man-hours.
