In legal practice, Hualong 1 reactor (HPR1000, known in the UK as the UK HPR1000) describes a Generation III pressurised water reactor technology proposed for new nuclear build, including as the reference design for the Bradwell B project in England. It is a technical designation, not defined in legislation or case law, and is used across licensing, planning, construction and financing documents.
In February 2022 the Office for Nuclear Regulation (ONR) and the Environment Agency (EA) completed the Generic Design Assessment of the UK HPR1000 and issued a Design Acceptance Confirmation (DAC) and a Statement of Design Acceptability (SoDA) for the generic design. These GDA outcomes do not authorise construction. Any specific project would still require, among other things, a nuclear site licence from the ONR, environmental permits from the EA (or the relevant environmental regulator), and a development consent order under the Planning Act 2008.
Usage and regulatory treatment are broadly consistent across England & Wales, Scotland and Northern Ireland, although planning and energy policy are devolved. In Ireland, the term is descriptive only, with no current deployment programme. Any deployment at Bradwell B remains subject to separate project approvals, investment decisions and applicable government policy.
