MEASUREMENT OF NEUTRON AND GAMMA SPATIAL DISTRIBUTION IN RADIAL CHANNEL AT VR1 REACTOR

摘要

This work gives the theoretical description with a practical measurement of neutron and gamma spatial distributions in a radial experimental channel (RC)at VR1 research reactor.For providing the measurements an “off line ” and “on line ” methods were used.The “on line ” measurement of neutron spatial distribution was performed with a 3 He gas filled detector. From the “off line ” measurements Neutron Activation method (for neutron detection)and Thermoluminescent method (for gamma radiation detection)were chosen.Results obtained from experiments were compared with the results from MCNP code.
