Application of rhodium self-powered neutron detectors for dynamic reactivity measurements in WWER reactors

Creators

Description

It is reported on three-dimensional investigations of the space-time neutron behaviour in power reactors by means of self-powered neutron detectors with Rh-emitters. With the technique described it is possible to measure the response of 30 detectors simultaneously. If the reactor power is disturbed by 5% the neutron flux signals measured by the SPN-detectors change by 3 to 11%. The greatest alternations are located close by the moved control rods and in the height of the perturbation position. (author)
