Boiling Water Reactor (BWR) Nuclear Instrumentation Solutions
Local Power Range Monitors (LPRM)
Miniature fission chambers for use with local and average power range monitoring.
Designed, manufactured and factory-tested to conform to American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section III, Nuclear Power Plant Components.
Reuter-Stokes has several decades of experience manufacturing gamma thermometers which have been used for calibrating LPRM fission chamber detectors in Boiling Water Reactor (BWR) plant designs.
Traversing In-Core Probe (TIP)
Gamma and neutron TIPs for LPRM sensor calibration and axial flux mapping.
With the improved accuracy of Gamma TIPs, there is also the potential for extending time intervals between LPRM calibrations.
Mechanical Drive Equipment: TIP drive and indexing mechanisms, tubing and guide tube/valve assemblies.
Source (SRM) and Intermediate (IRM) Range Monitors
Startup instrumentation sensors are calibrated for optimal measurements from below source level to ~10% of rated reactor power.
Wide Range Neutron Monitor (WRNM) combines functionality of SRM and IRM detectors into one solution.
Mechanical Drive Equipment: SRM/IRM detector drive mounts, motor modules, flex shafts, drive tubes, and shuttle tubes.
Safety
Innovative designs reduce dosages to personnel during replacement.
Efficiency
Eliminate the need for two separate probes and reduce time spent swapping probes.
Reliability
Engineered to avoid unplanned shutdowns and to ensure timely startups, rapid issue resolution, and effective delivery alignment with outage schedules and goals.
