发明名称 СПОСОБ ОПРЕДЕЛЕНИЯ ЭФФЕКТИВНОЙ ИНТЕНСИВНОСТИ ИСТОЧНИКА НЕЙТРОНОВ ЗАГЛУШЕННОГО ЯДЕРНОГО РЕАКТОРА
摘要 FIELD: experimental evaluation of nuclear reactor physical characteristics and estimating its effective multiplication factor and reactivity. ^ SUBSTANCE: proposed method includes displacement of absorption rods or other disturbance source in reactor core, determination of neutron field response to these displacements by means of neutron detector, and gamma-ray intensity measurements. Effectiveness of neutron source intensity is found from equation Qef(t)=klambdalambdad(t), where lambdad(t), is gamma-ray intensity; klambda is factor found in calibration experiment. This procedure needs no periodic repetition of displacing control rods affording reliable shutdown of reactor. Fission chambers are used as neutron and gamma-ray detectors. Gamma-ray intensity is measured by changing over fission chamber using integral current recording circuit. ^ EFFECT: enhanced reliability of measurement results, reduced amount of work involving handling of radioactive materials. ^ 3 cl
