Apparatus for measuring nuclear reactor power distribution.

摘要

An apparatus for measuring nuclear reactor power distribution comprises a Fourier coefficient calculation means and a transformation means, whereby Fourier coefficients of neutron detector outputs are transformed into Fourier coefficients of integrated values of the reactor power on each interval, and hence conditions required of data for initial calibration are made less severe and the initial calibration is enabled to be performed much easier. The apparatus further comprises an abnormal data deletion means, whereby detection and deletion of abnormal data are made easy so that the apparatus performs a stable operation with high accuracy.
