FIELD: on-line reactivity monitoring of nuclear reactor in wide neutron-flux variation range. SUBSTANCE: digital reactimeter has neutron detector, amplifier and pulse shaper, neutron meter, digital reactivity computer, display, printer, and statement. Neutron detector is, essentially, movable pulse-division chamber with digital detector of its position whose signal is entered in reactivity computer. EFFECT: enhanced precision of reactivity calculations in wide range of neutron flux variations. 1 dwg |
