Thermal modeling of waste cylinders in a large container

摘要

The Fuel Conditioning Facility at the Iadho National Engineering and Environmental Engineering Laboratory,INEEL,is to produce a spent fuel waste product which is essentially a heat-generating ceramic cylinder with a very tight-fitting stainless steel clad.The size of this waste product,which is under development,is such that many of then will fit into one of the large cylindrical containers being considered for use at the proposed Yucca Mountain repository in Nevada.A key concern is how to size the waste cylinders and arange them inside the container so that the space within the container is efficiently used and ceramic temperatures above about 600 deg C are not reached.
