Title:
NEUTRON FLUX MEASURING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/215192
Kind Code:
A1
Abstract:
A neutron flux measuring apparatus (100) comprises: a storage unit (12) for recording, as record data (D), measurement values showing changes in neutron flux in a nuclear reactor that occur in response to regulatory control of nuclear reactor output during a first set period; and a calculation unit (19) that, on the basis of the record data (D) and in accordance with the regulatory control during a second set period which is after the first set period, corrects a neuron detection value sensitivity of a self-powered detector (1) at a point of time (t1), which is a passing point of the second set period, and derives the neutron flux at the point of time (t1) using said corrected detection value sensitivity.
