Subject:

Crystal River Unit 3 Docket No. 50-302 Operating License No. DPR-72 ,

NUREG-0737, item II.F.2 Reactor Coolant System Water Level Measurement

Dear Dr. Mattson:

In your meeting of February 17 and 18,1982, you requested that each utility forward to you an estimate of the cost, time frame, and radiation exposure entailed in the installation of a reactor coolant system (RCS) water level measurement system. Florida Power Corporation (FPC) has developed such estimates for the B&W designed Hot Leg Level Measurement System (HLLMS). This includes both a narrow range (upper portion of the hot leg) and a wide range (reactor hot leg nozzle to top of the hot leg) subsystem. It does not include a reactor vessel head water level measurement subsystem. The estimates are as f

  • lows:

Very truly yours, A

David G. Mardis Acting Manager
