The. point is marked invalid if both inputs are invalid. Compensation for density changes occurs in the RVfIS process instrumentation cabinet.
The narrow range=
indicator provides valid information when. all RCPs; are-deenergized.
With all RCPs not running, the narrow;range"indication'ccurately reflects reactor vessel water level. With one or more RCPs running, the narrow range indication will show maximum level (due to the pressure drop across the core).
The top of active fuel is represented by a level indication of 618 on this instrument.

The indication is in percent of S/G level.
The top of the tube bundle is represented by a level indication of 578 on this instrument.

The transmitters provide the signal. for use in the Reactor Control, Protection, and Chemical and Volume control systems.
Each transmitter provides an independent high water level signal that is used to actuate an alarm and upon two out of three alarms will cause a reactor trip. The top of the heaters is represented by a level indication of 185 on this instrument.

N IEVEL REFERENCE LEG WET UNIQUE SYSTEM DESCRIPTION Senses reactor containment level. This point consists of the healthy average of the two level indications of the combined reactor building spray and residual heat removal sumps. If either level input is invalid the other is used. If both inputs are invalid, this point is marked invalid. The sump level indication comes on scale at 408 feet and each sump contains approximately 1800 gallons of water. At the 412 foot elevation the sumps are full with each"sump containing approximately 7360 gallons of water.
The reactor building floor is at an elevation of 412 feet.
A 6 inch high curb is present around each sump-and therefore the floor of the reactor building must contain 6 inches of water before the sumps begin to fill. This means that any level indication above 412.5 feet, represents both sumps full and that flooding in the reactor building is occurring.
The maximum flood level expected is 418.5 feet.
