Abstract :
A new method to determine neutron sensitivity of uranium-type local power range monitors (LPRMs) has been developed. In this method, neutron sensitivity of LPRMs is obtained from alpha-ray current of 234U. The uncertainty of the calibration for neutron sensitivity using alpha-ray current was 2.1%, and the correlation coefficient of these neutron sensitivities was 0.868 (sample: 50 cases). Using this method, the neutron sensitivity can be obtained without irradiation tests of LPRMs in reactors.
