Mohr Test & Measurement successfully installed new spent fuel pool monitoring equipment at the Cook nuclear plant, the Richland, Wash.-based company announced Monday.
The installation at the American Electric Power plant in Michigan will serve as a pilot as Mohr plans to install the equipment in all 14 reactors that are part of the Utilities Service Alliance. Including those, the company said it holds contracts to deliver 47 monitoring systems in the U.S. and abroad.
Following the Fukushima Daiichi accidents in Japan, the Nuclear Regulatory Commission implemented rules requiring that all U.S. reactors enhance their instrumentation to measure water levels in spent fuel pools. The model of the equipment installed at Cook is the EFP-IL, which was tested to meet the seismic and other requirements associated with all Utilities Service Alliance plants. Stainless steel probes feed Cook's SFP information to regular and backup displays in the control room through up to 650 feet of coaxial cable. According to Mohr's website, the water-level measurements are accurate to 0.1 mm. The instruments are also calibrated in-situ in real time and can characterize boiling environments.
