Spent Fuel Multi-Monitor System

The new 1E-qualified CL86 Plus Spent Fuel Pool Multi-Monitor System from Fluid Components International (FCI) integrates three critical measurements: continuous level, point level, and temperature into a multi-variable solution designed specifically for spent fuel pool (SFP) applications in nuclear power plants. Maintaining water levels within spent fuel pools is of vital importance to ensure that spent fuel is kept cool and insulated, preventing the release of radiation. The new CL86 Plus Monitoring System features integrated continuous water level, multiple point level wet/dry indication and alarms, and water temperature sensors. These precision sensors operate independently of one another, offering the reliability and dependable accuracy required in demanding nuclear power plant installations.

The CL86 Plus provides discrete and independent outputs of each measurement for interface with the plant control room and alarm systems. The CL86 Plus is ideal for both new and retrofit SFP installations. It consists of a unified probe assembly that is immersed in the SFP and manufactured to the exact length specified for the depth of the application. The sensor design is an extension of FCI’s proven thermal dispersion technology for the nuclear industry. Sensor wires and electronics interface junction box are housed in a rugged metal enclosure that is water-tight and resistant to falling debris.
