## Summary

The United Kingdom Atomic Energy Authority has completed a procurement process titled "Measurement of melting point and density of fluoride salt mixtures," focusing on chemical elements and compounds. The tender, which followed an open procurement method, sought to ascertain the properties of fluoride salt mixtures as potential coolants for fusion reactors. Key dates include the contract start on 2nd August 2021 and an end date on 31st August 2022, with a budget of £100,000 and a minimum bid value set at £50,000. The work was executed across various regions, specifically in the South East of the United Kingdom, and was marked as complete on 4th November 2021.

This tender represents significant opportunities for businesses specialising in physical measurement instruments, particularly those focusing on densitometers and similar analytical equipment. Companies capable of delivering high purity chemical processes and precision measurements would find this project aligns well with their offerings. Small and medium enterprises (SMEs) are particularly encouraged to engage, as the procurement process is designed to include suppliers that can demonstrate expertise and quality in chemical analysis and experimentation.

## Notice

There are several possible candidate classes of coolants for future fusion reactors, including molten salts, liquid metals, gases, and supercritical fluids. Some liquid coolants have advantageous thermophysical properties over other types of coolant. In particular, molten salts demonstrate good heat transfer, allow low pressure operation, and do not suffer from disadvantageous MHD effects as liquid metals do. To determine the feasibility of fluoride molten salts for this application, it is necessary to accurately determine the properties of salt mixtures at and around the melting point. The purpose of this project is to accurately determine the density and melting point of a range of fluoride salt mixtures. Compositions of five fluoride salts will be provided, and the melting point and density should be investigated. Specifically, the melting point of each composition and the density as a function of temperature around the melting point should be accurately determined. These measurements should be repeated for five variations of each base composition, including the base composition itself. A high purity should be maintained throughout the production and testing of the salts, to ensure accurate measurements are recorded.
