Frazer-Nash and Praxis have been contracted to advise the Health and Safety Executive (HSE) in its review of certain safety aspects of designs for the UK’s new generation of nuclear reactors.

The HSE, working with the Environment Agency, is currently assessing two different reactor types – the UK-EPR designed by Areva and EDF and the AP1000 designed by Westinghouse – for their suitability to meet UK regulatory standards, as part of its generic design assessment (GDA) process.

The HSE commissioned prime contractor Frazer-Nash and technical lead Praxis to provide technical support to produce independent advice on certain areas within its assessment.

The review will focus on control and instrumentation aspects of the reactor designs, including the reactor protection systems.

The findings of the work will support the HSE’s overall assessment of the designs and help to determine the extent to which they can meet the UK’s stringent safety assessment principles.

This will ultimately feed into the regulator’s decision-making process, helping the HSE to produce its report on the extent to which the reactor designs meet the UK licensing requirements.

Paul Deeran, nuclear business manager at Frazer-Nash, said: ‘Our support to the HSE as part of the GDA is critical in providing a third-party viewpoint on critical safety aspects of the two designs.’ Frazer-Nash is the prime contractor within a consortium of companies chosen by the HSE to provide technical support to the GDA process and news of this contract follows the consortium successfully securing a number of framework agreements with the regulator.

The work will be co-ordinated by Frazer-Nash’s Warrington team, the culmination of which will be a report by Frazer-Nash and Praxis that will be submitted to the HSE.
