Attachment to AEP:NRC:0628 Containment Water Level The Containment Water Level monitor consists of two redundant narrow range channels and two redundant wide range channels as shown on Figure 1 of this Attachment.
The narrow range channels would indicate the water level in the containment sump from elevation 589'-5" to elevation 599'-8".
The wide range channels would indicate the water level in the containment from elevation 599.'-3" to elevation 614'-0".
These wide range channels, would indicate more than 600,000 gallons of water.
There is a five. inch over-lap between the narrow and wide range channels.
The differential pressure transmitters used to'monitor Containment Water Level are located behind the crane wall at an elevation of 615'-0".
This elevation is above the flood-up level.
They transmit signals to indicators located on the RHR panel in the control room (see Figure No.
1 of this Attachment).
All channels were designed to meet the requirements of Appendix B
to NUREG-0737.
The transmitters are qualified to IEEE-323-1971 and IEEE-344-1975.
In addition, these transmitters are currently undergoing a type test qualification by ITT. Barton to IEEE-323-1974.
