Radiation heating up of structural materials in the field of impulse graphite reactor radiation

The description of PP experimental device used for in-pile researches of radiation heating up that introduces minimum distortion in neutron and a gamma field of IGR reactor was given in article. Presented models of PP-1, PP-2, PP-3 experimental devices provide the possibility of data acquisition for all tested materials in the conditions of controlled heat exchange and varied heat removal in reactor core. Besides, the results of neutron-physical calculations of PP-1, PP-2 and PP-3 experimental devices performed to justify the possibilities of testing of materials in conditions assumed complex influence of operation factors during the process of reactor operation are presented. The purpose of the numerical analysis is the calculation determination of energy release in samples placed at PP-1, PP-2 and PP-3 experimental devices and definition of values of effective neutron multiplication factor of 'ED RR-IGR reactor' system.
