METHOD FOR REGISTERING NEUTRON FLOW Russian patent published in 2005 - IPC

FIELD: nuclear reactors engineering.

SUBSTANCE: method includes conversion of nuclear division reactions into luminescent radiation in gas-filled detector, intensiveness of which is used to estimate value of neutron flow. Prior to measuring intensiveness of luminescent radiation it is outputted beyond biological protection of nuclear reactor along radiation-resistant light guide on basis of quartz with addition of protector ions with transparency windows 0.7-0.9 microns, 1.25-1.35 microns, 1.5-1.7 microns, and from selected luminescent gas substances in said transparency windows of light guide those are selected, wherein power of luminescent radiation linearly depends on value of neutron flow. As said luminescent gas substances mixtures of inert gases or mixtures of inert gases with molecular gases are utilized.

EFFECT: higher sensitivity of registration.
