BEIS opens GDA to Advanced Nuclear Technologies

11 May 2021

As regulators of the nuclear industry, the Environment Agency and the Office for Nuclear Regulation are working together to make sure that any new nuclear power stations built in the UK meet high standards of safety, security, environmental protection and waste management. We are scrutinising new nuclear power station designs thoroughly, making sure people and the environment are properly protected.

Generic design assessment (GDA) is the first step in this process.

Regulators respond to new guidance from BEIS on GDA entry process

The Department for Business, Energy & Industrial Strategy (BEIS) has today published its GDA Entry Guidance and opened the Generic Design Assessment to Advanced Nuclear Technologies.

The new Entry Guidance reflects the work that the nuclear regulators have completed to modernise GDA.

We updated our joint GDA guidance in preparation for this last year, and wait to be invited by government to start regulatory activity.

Generic Design Assessment (GDA)

We are currently assessing one new nuclear reactor design, the UK HPR1000.

Public comments process

The UK HPR1000 comments process is open throughout the GDA, until about four months before the end of the assessment.

General Nuclear System Ltd (GNSL) will continue to publish detailed design information on its website and update it as new information becomes available. Anyone can view that information and comment on it.

GNSL is required to respond to questions and comments about their design. We are able to see both the question and the response, so that we can consider them in our assessments.
