Aspects of the DWPF melter significant to waste acceptance

摘要

The repository program has established quality assurance requirements which are to be applied to activities and items which affect compliance with the Waste Acceptance Preliminary Specifications (WAPS). In this report, the aspects of the melter which are significant to meeting the WAPS are identified. Based on the Waste Form Compliance Plans (WCP), the melter plays a significant role in satisfying specification 1.3 (Product Consistency) by ensuring that feed material is sufficiently vitrified before the glass is poured into the canister. Aspects of the melter system important for meeting the WAPS are: administrative controls and process instrumentation which will be used to assure that glass pouring is not initiated at melt temperatures
