The AP1000® nuclear reactor, designed by Westinghouse, is suitable for construction in the UK said the regulators today following completion of an in-depth assessment of the reactor design.

The Office for Nuclear Regulation (ONR), the Environment Agency (EA) and Natural Resources Wales (NRW), the regulators who undertake the Generic Design Assessment of new reactor designs, are satisfied that the reactor meets expectations on safety, security and environmental protection at this stage of the regulatory process.

ONR has issued a Design Acceptance Certificate (DAC) to Westinghouse and the environment agencies have issued a Statement of Design Acceptability (SoDA).

Dr Richard Savage, ONR’s Chief Nuclear Inspector, said:

The closure of our assessment of the generic design of the AP1000® reactor is a significant step in the process, ensuring the design meets the very high standards of safety we expect.

We will now focus our regulatory attention on site specific assessments, and NuGen’s application for a nuclear site licence.

Dr Jo Nettleton, Deputy Director for Radioactive Substances and Installations Regulation at the Environment Agency, said:

Successfully completing GDA means that the AP1000 is capable of meeting the high standards of environment protection and waste management that we require.

We’re already working with NuGen, as it develops its proposals to build and operate three AP1000 reactors at Moorside in Cumbria, to ensure that those high standards are delivered.

The regulators required 51 GDA Issues to be resolved before confirming the suitability of the AP1000. All of the issues have been addressed to the regulators’ satisfaction enabling the DAC and SoDA to be issued. The regulators’ assessment reports are all available online

Notes for Editors

1. The Office for Nuclear Regulation is the nuclear safety and security regulator for the UK.
2. The Environment Agency and Natural Resources Wales are the environmental regulators of nuclear sites in England and Wales respectively.

5. The DAC and SoDA are valid for a period of ten years from issue and can be extended subject to review and agreement of the regulators.
6. The issuing of a DAC/SoDA does not mean the construction of the reactor can start. Before a new nuclear power station can be built, the operator (NuGen in this case) must obtain a number of site specific permissions from the regulators and Government, including a nuclear site licence and relevant consents, environmental permits and planning permission (Development Consent Order). https://www.gov.uk/guidance/guidance-for-operators-of-new-nuclear-power-stations
7. The Statement of Design Acceptability (SoDA) is being issued jointly by the Environment Agency and Natural Resources Wales. GDA applies to both England and Wales.

In 2011 the Environment Agency published its decision document setting out its detailed assessment of environmental aspects of the UK AP1000® nuclear power station design. It used the comments and issues raised in the 2010 consultation to help inform its decisions.

Since December 2011, the Environment Agency has been assessing the further information Westinghouse provided.

The environmental regulators have now issued a full SoDA. This supplement to the 2011 decision document explains developments since 2011 and why they have issued a SoDA.

The regulators conclude that the environmental aspects of the design would meet the high standards they expect, and have decided to issue a SoDA for the design.

The Office for Nuclear Regulation has also published its Design Acceptance Confirmation.

This publication provides the latest provisional estimates of UK greenhouse gas emissions based on provisional inland energy consumption statistics, which are published in BEIS’s quarterly Energy Trends publication.

For the purposes of reporting, greenhouse gas emissions are allocated into a small number of broad, high level sectors as follows: energy supply, business, transport, public, residential, agriculture, industrial processes, land use land use change and forestry (LULUCF), and waste management. Additionally provisional emissions for Carbon Dioxide (CO2) only are allocated into broad fuel classifications as follows: gas, oil, coal, other solid fuels and non-fuel.

These provisional emissions estimates are subject to revision when the final estimates are published; however, they provide an early indication of emissions in the most recent full calendar year.

The Environment Agency consults the public on certain applications for waste operations, mining waste operations, installations, water discharge and groundwater activities. The arrangements are explained in its Public Participation Statement

These notices explain:

• what the application is about
• which Environment Agency office you can visit to see the application documents on the public register
• when you need to comment by

The Environment Agency will decide:

• whether to grant or refuse the application
• what conditions to include in the permit (if granted)
