sensing technology that will be The instrument is a guided wave radar determined during the detailed system. It provides the capability to engineering phase of the project. reliably monitor the spent fuel pool water level under normal and anticipated adverse environmental conditions.
The sensor input to the system is a guided wave radar probe. Using the principle of time domain reflectometry (TOR) to detect the SFP water level, microwave signals are pulsed down the cable probe and reflected back from the water surface. This is used to determine the level of the water in the pool.
Each water level measurement channel includes a flexible stainless-steel sensor cable probe suspended in the spent fuel pool from a seismic Category 1 bracket attached to the operating deck or to a raised curb at the side of the pool. The cable probe extends to just above the top of the spent fuel racks. The sensor electronics are mounted in seismic and missile protected areas outside of the building housing the SFP to minimize exposure to elevated radiation and environmental conditions which could result from a postulated loss of water inventory in the pool. There is an interconnecting cable between the Page 3 of9

The sensor electronics provide an instrument standard analog signal to a remote enclosure that will be installed in an accessible location. This enclosure contains the Uninterruptable Power Supply (UPS), backup battery, and water level display. The enclosure also includes the capability to connect an emergency or temporary external power source .as part of the FLEX mitigating strategies.
