WRM 501™
Wide range monitor used with fission chamber for ex-core neutron flux monitoring in the start-up range.
Features
- Qualified to perform safety functions
- Seismic qualification
- Available with fission chambers of various sensitivities
- High longevity due to the robustness of fission chambers
- LOCA proof fission chambers are available
- Wide measurement range (combined pulse + Campbell (AC) mode) up to 12 decades
- Signal filtering with adaptive time constant
- Calibration to neutron flux signal or reactor power (nv, %FP)
- Calculation of the relative flux change rate (reciprocal of the reactor period) or rate of change of reactor power (in decade/min)
- Linear and/or logarithmic analog outputs
- Generation of analog and binary outputs for the reactor protection system
- Built in test signal generators (remote activation possible)
Description
The wide range WRM 501 monitor forms part of the digital Neutron Flux Monitoring Systems (NFMS) proTK™ product line. It is used, in combination with fission chamber, for ex-core neutron flux monitoring in the start-up range.
The associated DWK 250™ processing unit has been designed and is qualified (in hardware and software). It provides functions that can be used at the level of the reactor protection system.
