## Summary

The Health & Safety Executive is conducting a procurement for technical support related to the independent analysis of the UK HPR1000 in-vessel melt retention strategy. The tender, titled "Provision of Technical Support to Perform an Independent Analysis of the UK HPR1000 In-Vessel Melt Retention by External Reactor Vessel Cooling Strategy," falls under the classification of research and development services. The procurement method used is selective, and the contract, which has a value of £347,787, was awarded on 25th September 2019, with a contract period running from 1st October 2019 to 31st December 2020. The tender process concluded on 5th August 2019 and the project encompasses delivery across various locations, including the United Kingdom and other territories.

This tender presents significant opportunities for businesses specialising in technical consultancy and engineering services within the nuclear sector. Companies with expertise in severe accident scenario modelling, reactor safety analysis, or related fields would be particularly well-equipped to compete for contracts generated through this procurement. Engaging with frameworks such as this can enhance a business’s portfolio and reputation, particularly given the emerging safety standards and technologies demanded in the energy and nuclear industries.

## Notice

ONR is seeking to engage one the Technical Support Contractors (TSC) appointed on Lot 1 of its Technical Support Framework. The TSC is required to agree with ONR a strategy to independently confirm the validity of claims made on in-vessel retention ex-reactor vessel cooling strategy, based on the response to this specification. This includes the severe accident scenarios to be modelled. This should occur shortly after award of the contract. Request from the RP the information needed to develop independent computer models (which ONR will formally submit to the RP as written Regulatory Queries (RQs)). For planning purposes the contractor should assume that data will be provided 6 weeks after each request. It is likely that several information requests will be required in order to ascertain all data required to build the model and run the SA scenarios. Develop a UK HPR1000 model capable of modelling severe accident scenarios from initiating event to RPV failure or steady state. The model should include an appropriately detailed core and RPV lower head, a containment, a primary circuit thermal hydraulics model and an IVR tank and recirculation loop (if necessary). Perform confirmatory analysis on a range of severe accidents scenarios
