Supplier Information

 Cover of the Radioactive Waste Management Directorate Supplier Workshop Report

PDF Supplier Feedback from Geological Disposal Facility Workshop January 2009 (1Mb)
NDA hosted an event for potential suppliers to understand more about the programme to implement geological disposal. Delegates contributed their views to help develop the Contracting and Commercial Strategy for Geological Disposal Facility.


2007 Inventory (wastes to be managed)

 UK Waste Inventory Website

See UK Radioactive Waste Inventory 2007 Website for the following documents:

Executive Summary (2008)
This summarises the 2007 UK Radioactive Waste Inventory and provides an overview of the amounts of raw waste that either exist or will arise in future.

Main report (2008)
This is the detailed document that provides information on volumes that exist today and will arise in the future.



International data report (2008)
This provides the necessary information required for international reporting to the IAEA.

Review of processes contributing to radioactive waste in the UK (2008)
This report explains how and why radioactive wastes are produced in the UK. Its purpose is to inform those who have no involvement with radioactive waste about the primary processes that give rise to radioactive wastes and how these wastes are dealt with.

Radioactive materials report (2008)
This report provides details of those materials that are not currently classified as waste e.g. plutonium, uranium and spent nuclear fuel, but may be classified as such in the future.

Planning for geological disposal

 Cover of Nirex report

PDF The viability of a phased geological repository concept for the long term management of the UK’s radioactive waste (Nirex Report (N/122) 2005) (2Mb)
This report sets out why Nirex believed that the UK’s long-lived radioactive waste should be placed in a phased geological repository located between 300 and 1,000m deep in stable rock and the reasoning behind these views.


Cover for options for geological disposal 

PDF Geological disposal options for HLW and SF (2008) (7Mb)
This report provides information on a range of high level radioactive waste (HLW) and spent nuclear fuel (SF) geological disposal0020concepts, in order to illustrate how geological disposal of HLW and SF might be implemented in the UK.



 Cover for report

PDF Concepts for the geological disposal of ILW (2008) (10Mb)
This report provides information concerning the phased geological repository concept (PGRC) which has been developed as the reference option for geological disposal of intermediate level wastes (ILW) and those low level wastes (LLW) not suitable for disposal at the LLW facility near Drigg in Cumbria or at other future near-surface facilities in the UK. 


 Nirex Report Cover

PDF CoRWM Context note 2.6: Repository design and construction (2005) (150Kb)
This note is one in a series that summarise the issues, experience and status in topics that are relevant to the development of a geological facility for the long-term management of intermediate-level and certain low level radioactive waste in the UK.

This study investigated the co-disposal of low level waste, intermediate level waste, high level waste and spent fuel and summarises the key issues associated with this. 


 Position Paper

PDF RWMDPP01 Management of wastes from new nuclear power stations position statement February 2009 (38Kb)
As the implementing organisation for geological disposal of higher activity wastes, NDA is supporting the regulators’ Generic Design Assessment of designs for new nuclear power stations. In particular we are considering the disposability of spent fuel. We are examining a number of issues related to the characteristics of this waste and identifying their effects on the long term safety case for disposal.
Early results show that any issues identified are being addressed for the existing legacy wastes and nuclear materials.
