Mr. B. J. Youngblood Licensing Projects Branch No. 1 Re: McGuire Nuclear Station Docket Nos. 50-369 and 50-370
Dear Mr. Denton:
My letter of September 17, 1980 discussed the McGuire Nuclear Station in-core thermocouples in relation to a new NRC position. The information contained herein supplements that provided in my earlier letter.
The primary means of monitoring the in-core thermocouples is the Operator Aid Computer (OAC) as described in my letter of September 17, 1980: Any of these thermocouples can also be monitored on a thermocouple readout panel lecated near the rear of the control room. The thermocouple readout range is from 100 F to 700 F.
If the readout should go offscale high, each thermocouple can be measured by using a millivolt potentiometer at this readout panel.
The McGuire subcooling monitor uses as inputs the in-core thermocouples as measured by the OAC.
The display of this monitor is called up on operator demand. The McGuire operators have been instructed in the use of this monitor and will call up the monitor display whenever appropriate.
In addi-tion, the operators have been instructed to call up the monitor display when-ever the monitor alarms.
Very truly yours, N
William O. Parker, Jr.
