## Summary

Nuclear Restoration Services Limited, a public authority based in Warrington, UK, recently completed a procurement process for a project titled "SGHWR Reactor Dose Modelling". The procurement fell under the computer-related professional services category and was aimed at confirming the possibility of man entry to conduct site works. This process was conducted directly and below threshold, without competition, and was classified as services. The initial contract, signed with Cavendish Nuclear on 17th November 2025, commenced on 18th November 2025 and concluded on 27th February 2026. The contract has since been terminated upon completion, with the final report accepted on 5th May 2026. The total contract value was £41,932.51 gross.

This tender offered significant growth potential, particularly for businesses specialising in computer-related professional services. Given the nature of the services required, large-scale suppliers like Cavendish Nuclear, which specialises in complex nuclear sector projects, were well-suited to respond. Future similar opportunities could appeal to other large or specialised firms with expertise in reactor dose modelling and related site safety assessments. Engaging in projects of this scope can enhance a company's portfolio and reputation within the nuclear restoration sector, providing pathways to further commissions.
