Influence of Radiation-Stimulated Changing Thermophysical Properties on Reactor Graphite Resource

Analysis of modern investigation conditions of reactor graphite productivity shows that many parameters influence resource values. One can select some of them: flow density of deteriorated (E_n>0,18 MeV) neutrons, flow density of accompanying gamma-radiation, equivalent radiation temperature etc. They are the functions of time and markedly change during operating process of uranium graphite reactor. The aim of the given investigation is to determine the influence of thermophysical properties degradation on the resource of reactor graphite based on the methods outlined in [Boiko et al., 2004].
