Verification of the Neutron Flux of a Modified Zero_power Reactor Using a Neutron Activation Method

摘要

This work verifies t he neutron flux for a modified zero-power-reactor facility using neutron activation. Ten foils are activated and counted to illustrate the precise neutron spectrum at a particular location inside the reactor core through the computrerized software Spectrum Analysis by Neutron Detector-II (SAND-II). In addition, neutorn spectra derived from 11 different locations are compared with the computatioanl results from the WIMS reactor analytical software respectively, and then the neutorn distribution with various energy groups inside the reactor core is rearranged.
