SRM 502™
Source range monitor used in combination with fission chamber for ex-core neutron flux monitoring in the start-up range.
Features
- Qualified to perform category A functions according to IEC 61226 and KTA 3505 (for safety-related instrumentation)
- Seismic qualification (IEEE 344 and KTA 3505)
- Available with fission chambers of various sensitivities
- High longevity due to the robustness of fission chambers, LOCA proof fission chambers are available
- Large measurement range
- 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)
- Optional: reactimeter
Description
The source range SRM 502 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 DAK 250-i™ processing unit has been designed and is qualified (in hardware and software) to meet category A requirements, applicable at the level of the reactor protection system.
