Thermal scattering cross-section of light water and reactivity temperature coefficient for UO{sub 2} and UO{sub 2}-PuO{sub 2} water moderated lattices

Abstract

The reduction of the persistent discrepancy in the isothermal temperature coefficient is an important objective for reactor safety and design. Many attempts of reactor physicists to reduce this discrepancy on physical ground have been done. Some of these are now partly successful like the modification of {eta} thermal shape of {sup 225}U. However, the main part of the discrepancy remains to be removed. To contribute to this difficult task, we focus our attention on the thermal scattering cross-section of light water as a possible cause to disagreement. For this purpose, we have determined the sensitivity of the temperature coefficient to major parameters of the thermalization water model of Keinert-Mattes.
