Question

To ask the Secretary of State for Energy and Climate Change, what assessment her Department has made of the safety, sustainability and absence of risk to the environment of methods available for disposing of radioactive waste.

Government policy on disposing of higher activity radioactive waste is based on a comprehensive review of all the available options for existing wastes originally carried out by the independent Committee on Radioactive Waste Management between 2003 and 2006. Based on their consideration of all the evidence, including international best practice and scientific advice, they recommended geological disposal in an engineered facility at least 200m below ground as the best available option.

The independent nuclear safety, security and environmental regulators will only allow a Geological Disposal Facility (GDF) to be built and operated if they are satisfied it will meet their demanding regulatory requirements. The developer of any GDF will be required to present a detailed set of safety arguments for all aspects of a proposed facility. This includes everything from transporting the waste to the facility, to its design, construction and operation and safety in the long term, following closure.

Disposal routes for low level waste are already in operation in the UK. All proposals for radioactive waste disposals, including existing low level waste disposals, are subject to permitting by the Environment Agency who require operators to demonstrate that they are applying the best available techniques.
