IONISATION FISSION CHAMBER FOR DETECTING FAST NEUTRONS Russian patent published in 2021 - IPC G21D3/00

Abstract RU 2743849 C1

FIELD: physics.

SUBSTANCE: invention relates to neutron flux measurement devices, in particular to equipment for control and protection systems of nuclear reactors, and is used as a primary converter of an in-reactor neutron flux density monitoring channel. Proposed invention is based on coaxial electrode system, radiator material in which is Thorium oxide ThO₂ coating. Content of isotope ²³²Th (has threshold value of fission cross section by neutrons in 1 MeV) in natural raw material is 100 %, which eliminates reduction of information content of signal when detecting fast neutrons due to presence of isotopes sensitive to thermal neutrons.

EFFECT: technical result is registration of exclusively "fast" component of neutron flow (from 1 eV to 20 MeV) in active zone of reactor in conditions of stationary operation mode, transient periods of stopping, starting and outputting nuclear reactor to full capacity without using retarders.
