IAEA Nuclear Data Library / Thermal Scattering Law

The calculations of the thermal scattering law data

Background:
The calculations of the thermal scattering law data were performed a long time ago and were tailored to the computer technology of the sixties.

Since then the calculations were repeated for the ENDF/B-VI library, but with essentially the same input data, except for a somewhat extended energy transfer range. Water is the most widely used moderator/coolant in nuclear reactors. Zirconium hydride is used in TRIGA research reactors, which are operated in many laboratories in the world.

Furthermore, there are ideas to use zirconium hydride in the thermal island of accelerator driven subcritical systems for waste incineration. Improved data for hydrogen bound in water, hydrogen bound in zirconium hydride, and deuterium bound in heavy water would be desirable firstly because of its importance and secondly because of the identified problems

Objectives
Produce an improved library of thermal scattering law data for hydrogen bound in water, hydrogen bound in zirconium hydride, and deuterium bound in heavy water.
