Development of the Nirex Generic Transport Safety Assessment to Assist in the Provision Advice of Waste Packaging

AbstractThe current Nirex mission is to provide the United Kingdom with safe, environmentally sound and publicly acceptable options for the long-term management of radioactive materials. As part of this role, Nirex has developed a phased deep geological disposal concept which is defined by six ‘generic documents’ that describe systems, processes and safety assessments that are not specific to anyone location or geology. These generic documents give access to detailed information about the ideas and approaches that underpin the phased disposal concept, and have been published with an invitation to enter into dialogue with Nirex regarding these issues. The generic documents identify the requirements for an integrated transport system that would be necessary for the management of the intermediate-level (ILW) and low-level (LLW) wastes within Nirex's remit — the so-called reference case volume. This has involved Nirex in the development of transport hardware and associated safety reports and modelling and ass...

Nirex—the Complete Package

AbstractThrough continuous interaction with its customers, Nirex identified the need for a comprehensive range of waste containers, reflecting the variety of wastes and operational undertakings. The current range consists of five standard containers. Standardisation is introduced across all waste packages to enable the safe and efficient operation of future waste management facilities. The practical lessons learned during the development of standard containers are in turn reflected in the container design work that Nirex has undertaken. They are also fed into the advice given to customers during evaluation of waste packaging proposals.
