Wide range linear channel

The Wide Range Linear Channel (WRLC) consists of an unique neutron flux 

The Wide Range Linear Channel have both linear and log outputs over its whole operating range. 

The Wide Range Linear Charmel measures the reactor s neutron flux from the source 

Power Regulating System (RPRS) to allow an automatic control of the reactor power.

A Fission Chamber suitable for operation in both Pulse and Campbell modes is used as the detector in the Wide Range Linear Channel. 

The commercial units have a very low thermal capacity and very high response speeds. Some are available with several independent channels and a common cold junction. Each channel is scanned in turn by the instrument, and the readings either displayed or stored for future recovery. Accuracies of better than 0.2 per cent are possible. Thermocouples are available to cover a very wide range of temperatures, their cost is low and they have a small mass, so minimizing the intrusive effect on the surface at the point where the temperature is being measured. The output characteristics (output voltage versus temperature) are reasonably linear but the measurement accuracy is not particularly high.
