The Rolls-Royce Boron meter provides nuclear power plant operators with a permanent record of the boron concentration contained in a water cooling circuit by way of continuous sampling.
The equipment performs real-time measurements and processes them to compile assorted information that can be displayed or transmitted to other digital or analogue systems within the power plant unit. All of this information is generally used in the process to drive the reactor power.
One of the most important actions generated by the equipment is the “dilution alarm”, which automatically activates in case of an unexpected homogeneous dilution of the boron concentration.
Rolls-Royce standard equipment includes; a sampling tank, neutron source, neutron detector, temperature probe, a rack that supports the conditioning and process electronics, and process display.
