Creating Standardised Waste Packages
This page contains Nuclear Waste Services (NWS) Waste Package Specifications and Guidance for waste packages destined for geological disposal.
NWS have produced a suite of specifications and guidance for the safe disposal of the UK’s Low Heat Generating Waste (LHGW), High Heat Generating Waste (HHGW) and Depleted Natural Low Enriched Uranium (DNLEU). The Waste Package Specifications and Guidance form a suite of documentation that are organised on the website as shown in the interactive figure below. The specifications are organised in a hierarchical structure where the requirements from the Disposal System Specification (DSS) Part A cascade through to the Waste Package Specifications (WPS) Part D in increasing detail. The role of each specification is as follows:
- The Disposal System Specification Part A defines the high level requirements for the Disposal System.
- The Disposal System Specification Part B defines the technical specification for the Disposal System.
- The Part C Specifications define the envelope in which to develop new waste package designs for their chosen category of waste.
- The Part D Specifications detail existing container specific requirements.
Guidance provides supporting information and considerations to ensure the requirements in the Part C and D Specifications are achieved.
