## Summary

The Health & Safety Executive is seeking technical support services to conduct independent confirmatory safety analysis for the UK HPR1000 reactor. The tender, titled "Provision of technical support services to perform independent confirmatory safety analysis," is classified under the industry category of research and development services and related consultancy services. This procurement process is at the award stage, having been completed with the contract awarded on 28th June 2019. The contract period commenced on 1st July 2019 and will conclude on 1st March 2021, with a total contract value of £1,454,832. The procurement method follows a selective approach, being a call-off from a framework agreement. The tender period ended on 19th March 2019.

This tender presents significant opportunities for businesses specialising in nuclear safety analysis, thermal hydraulics, and computational modelling. Companies that have experience in developing reactor physics models or those involved in the technical support of nuclear facilities would be well-suited to compete. Engaging in this procurement could enhance a firm's portfolio and visibility in the growing nuclear safety sector, particularly given the project's technical complexity and importance in the regulatory landscape.

## Notice

ONR is seeking to engage one of the Technical Support Contractors (TSC) appointed on Lot 1 of its Technical Support Framework. The TSC is required to develop a thermal hydraulic system code computer model of the UK HPR1000. 1) A pragmatic approach to its development should be taken to ensure the model can be applied to a selection of fault transients without expending unnecessary effort developing redundant capabilities that are not required. 2) The computer model should utilise a point kinetic approach for the reactor physics for the initial work scope. However, the model should be developed with a view to coupling with the more sophisticated reactor physics model in the final phase. 3) The computer model should include a basic consideration of containment response. A more detailed containment model is not envisaged at this time but there is value in providing the capability and flexibility to develop and couple such a modelling if containment behaviour emerges as an area of regulatory interest. Develop a Core Physics computer model of the UK HPR1000. 1) The TSC will use geometric and isotopic data to derive a set of neutron cross sections for each proposed fuel assembly type as a function of irradiation and other suitable dependencies. Given the proposed fuel loading pattern, this will be used to determine the nominal power distribution for full-power conditions. The nuclear data derived will need to take account of the spectral history of each fuel assembly in the equilibrium core to determine appropriate nuclear data. 2) The TSC will use the nuclear data produced in 1) to develop a 3D, transient core model suitable for use as part of a wider model for the purposes of fault transient analysis. The adequacy of the predicted steady state performance will be confirmed by comparison against core power-distribution data supplied.
