X.1.30.3.4 Containment Pressure Monitor Two Class 1E redundant drywell chamber pressure measurements will be provided as follows:
SERVICE RANGE LOCA Range HI Range 0 to 65 psia 0 to 250 psig The LOCA and HI ranges are divided into two divisions.
Continuous, individual indication of all four Division I and II pressure measurements will be provided by indicating recorders for the operation on front row panels 1C601.
Normal operating pressures in the drywell and wetwell are monitored by a -1 to 3 psig instrument installed in each chamber.
An indicator on control panel 1C601 will display these pressures.
A selector switch is provided to allow the operator to monitor'either drywell or wetwell pressure.
These instruments are non-safety grade with the exception of the transmitters which are designed to meet containment pressureboundavy service.
The accuracy of these instruments as
+
2% of full scale.
The containment accident range pressure monitors are designed to be safety grade.
This equipment will be qualified to IEEE-344-1975, IEEE-323-1974 and NUREG 0588 in accordance with the Commission order on May 23rd, 1980 (CLI-20-81).
The containment pressure instrumentation will be installed by January 1982.
