Dear Sir:
I This letter provides you with additional information relative to the design l
details of the Scr a Discharge Header Monitoring Instrumentation to be in-stalled at Pilgrim Station.
Specifically, in addition to the Control Room annunciation for high water level in the Scram Discharge Header as described in Reference a), we will install j
lights in the control room for all four detectors. Each detector will have two lights, one to signal Scram Discharge Header "high" level, the other to signal
" equipment power failure".
Should you have any further questions on this subject, please do not hesitate to contact us.
i Very truly yours, Y2 R. D. Machon
