Details of the application
In June 2022 NNB Generation Company (HPC) Limited applied to us to change its existing radioactive substances environmental permit for Hinkley Point C Nuclear Power Station.
Pressurised water reactors at Hinkley Point C will use uranium fuel to create heat and generate electricity when operating. Once used within the reactor, nuclear fuel (radioactive waste) will be stored on-site before being sent off-site to a Geological Disposal Facility (GDF).
We issued the original radioactive substances environmental permit in 2013. In the original design radioactive waste was to be stored on-site in ‘wet storage’ - a method of submerging and storing in water.
The operator has now decided to change the technology by which it will store radioactive waste, from wet storage to ‘dry storage’. Dry storage will see radioactive waste stored in sealed containers within a facility before it is sent to the GDF. This means the operator now seeks to change its radioactive substances environmental permit to remove or amend specific conditions related to the previous wet storage technology that are no longer relevant.
NNB Generation Company (HPC) Limited is not seeking any changes to the site boundary, permitted activities or permit discharge limits. There is no change in the radiological impact to members of the public or non-human biota resulting from discharges.
Separately, NNB Generation Company (HPC) Limited will be seeking the necessary changes to its Development Consent Order (DCO) for Hinkley Point C.
