Nuclear Properties of Reactor Materials

In a heterogeneous reactor such as N Reactor various materials other than fuel and moderator are required to give structural support transport coolant support the fuel elements and contain the fuel Materials are critical from both a physical standpoint (resistance to corralon strength heat transfer properties etc ) and a nuclear standpoint (neutron absorption cross sectlonj resistance to radiation damage etc )  

The physics of nuclear reacV rs deals primarily with the congpetltlve nuclear reactions which take place In the reactor In order to determine the Important reaction rates. It is necessary to hnow the nuclear properties of the vaiplous reactor materials Of Importance In this regard, are 1) the neutron cross sections,
