Research into a measurement technique for UF3 and UF4 ratios in Uranium Fuel Salts

Terrestrial Energy are currently looking to establish a supply of Uranium based fuel salts for its Integrated Molten Salt Reactor (IMSR) testing programme and to support this establishment work NNL and Westinghouse are proposing to undertake a testing programme on Uranium based fuel salt materials to support the manufacture of this fuel at the NNL Preston laboratory. NNL and Westinghouse have agreed an analytical specification for the manufactured fuel to meet the requested specification requirements of Terrestrial Energy. However, there is a gap in the combined analytical capability, for the determination of the ratio of UF3 to UF4 material in any given sample of fuel salt to be tested. NNL are therefore looking to procure services for this element of the scope.
