Copenhagen Atomics<\/strong> and Urenco<\/strong> have signed a memorandum of understanding to design a deconversion plant in Copenhagen that will turn uranium hexafluoride (UF6) into uranium tetrafluoride (UF4). The facility will be built inside the site where the Danish company will produce fuel for its molten salt reactors.<\/p>\n

The agreement has a second element. Copenhagen Atomics has already purchased low-enriched uranium (LEU) from Urenco for its first reactors. Fuel supply and deconversion capacity in Europe are therefore coming together, and according to the two companies this moves the reactor development timeline forward.<\/p>\n

The deconversion line is part of a tonne-scale fuel salt production plant, which Copenhagen Atomics describes as the first of its kind in the world. Urenco brings its experience with UF6. The Danish company provides the engineering expertise to build and operate the site. Chief technology officer Aslak Stubsgaard said the company is very proud to have chosen Urenco.<\/p>\n

The reason lies in the chemistry of the fuel. Thorium-fed molten salt reactors, such as the Copenhagen Atomics Waste Burner<\/strong>, need UF4 to prepare the fuel salt. Enriched uranium, however, leaves Urenco’s plants as UF6, the gaseous compound used in enrichment. An intermediate step is therefore needed to convert it. Until now, Europe has had no dedicated line for this purpose for reactors of this type.<\/p>\n

The Waste Burner is a 50 MW thermal design, with an expected electrical output of 20 MWe. It uses heavy water as moderator and fluoride salts as fuel. The company follows a component-by-component path, testing one element at a time, and has already built full-scale prototypes that run on non-radioactive salts. Having a fuel supply chain in Denmark makes it possible to link those tests to the phase involving nuclear material.<\/p>\n

Urenco, for its part, has spent years working on fuels for Generation IV reactors. The group plans a facility at Capenhurst, in the United Kingdom, for uranium enriched up to 20%, the first of its kind in Europe. The agreement with Copenhagen Atomics extends its reach to a customer that needs smaller, customised supplies.<\/p>\n

If the project goes ahead, Denmark will host a link in the fuel chain that the continent currently lacks. For molten salt reactor builders, it would mean being able to buy uranium, convert it and load it into the salt without leaving Europe.<\/p>\n","protected":false},"excerpt":{"rendered":"
