## Summary

The National Nuclear Laboratory Limited, based in Warrington, England, has completed a procurement process for specialised research and development services in the reactor physics and criticality domain. This tender, titled "Reactor physics and criticality: (a) Development of high-fidelity coupled methods for the steady-state and transient analysis of coated particle fuels, and (b) evaluation of criticality implications associated with HALEU," was issued under the NNLC321.03 contract. The procurement followed a selective method through a call-off from a framework agreement, valued at GBP 295,000. The contract period ran from 7th August 2024 to 31st March 2025, with services provided by The University of Manchester. The main procurement category for this tender is services related to research and development consultancy.

This tender presents significant opportunities for businesses specialising in high-fidelity coupled methods or criticality evaluation, particularly those adept at handling High-Assay Low-Enriched Uranium (HALEU). The awarded contract for research and development opens pathways for firms engaged in advanced nuclear research to collaborate with renowned institutions like The University of Manchester. Although this tender did not favour SMEs or VCSEs, it indicates a substantial investment in innovative nuclear technologies and methodologies, encouraging specialised research entities to align their capabilities with future public procurement opportunities in this sector.
