HYDROGEN MODERATION - A PRIMARY NUCLEAR SAFETY CONTROL FOR HANDLING AND TRANSPORTING LOW-ENRICHMENT UF6

摘要

The use of hydrogen moderation as a primary nuclear safety con-trol has been in effect for many years for large-scale UF6 shipments among AEC-owned contractor operated facilities. Since it appears that the extension of the use of moderation controlled shipments to licensee as well as contractor organizations is desirable, this report summarizes, in support of the method, the work done in developing basic criticality data and the necessary equipment and operational techniques.
