A method of water level detection in boiling water reactors using the ~(16)N decay

摘要

An experimental simulation of water level detection in boiling water reactors is presented. The water in a vertical pipe was irradiated with fast neutrons produced by a neutron generator, whereby ~(16)O was activated to ~(16)N. Two EGO detectors along the pipe at two different heights measured the gamma radiation at different water levels. The ~(16)N detection in a boiling water reactor could thus be simulated in an experimental set-up with a minimum of other sources.
