Description

The BM 501 boron meter forms part of the proTK™ product line. The BM 501 meter is designed to continuously measure the boron concentration in water circulating in process of light water nuclear power plants. The measurement principle is based on measuring the neutron absorption rate through the B-10 isotope, which depends on the boron concentration contained in the water coolant.

The neutrons are generated by an internal source, which is part of the detection sub-assembly.

SG 65/66 NaI Scintillators

The SG 65 and SG 66 scintillators have been developed for safety related monitoring of activity according to KTA 1502. In the scintillator crystal, ionizing radiation generates light pulses, which are converted and amplified into charge pulses by the photo multiplier.

The height of the pulse is proportional to the energy of the gamma radiation. An adjustable pulse amplifier offers calibration of the sensitivity and matching of the output pulses to the impedance of the detector cable.
