Fluid Components International (FCI) has launched a new spent fuel pool multi-monitor system, which integrates three critical measurements: continuous level, point level and temperature.
The system, the CL86 Plus Spent Fuel Pool Multi-Monitor System was developed in response to the ‘critical process need’ for monitoring spent fuel pool conditions, which was highlighted by the Fukushima Daiichi accident.
The new system features integrated continuous water level, multiple point level wet/dry indication and alarms, and water temperature sensors. The sensors operate independently from one another, offering the reliability and dependable accuracy required in demanding nuclear power plant installations, FCI said.
The CL86 Plus is suited to both new and retrofitted spent fuel pools, according to FCI, and since the events at Fukushima, it has already been selected by some nuclear power plants for spent fuel pool level measurement.
The US Nuclear Regulatory Commission has recently (March 2012) issued an order EA-12-051, and interim staff guidelines, which outlines requirements for SFP level measurement and the time lines for its implementation.
It determined that all power reactor licensees and construction permit holders much have a reliable means of remotely monitoring a wide-range spent fuel pool levels to support effective prioritization of event mitigation and recovery actions in the event of a beyond-design-basis external event.
The vendor says that its CL86 Plus meets system or exceeds all requirements currently being proposed by the Nuclear Energy Institute (NEI) and Nuclear Regulatory Commission (NRC) for SFP monitoring.
