Table 3: Needs for metallisation and deconversion
U-Zr alloy Fast reactors Lightbridge fuel for LWRs U-metal UF6 → U-metal

Does this mean that the Lightbridge metalisation method is required for use with LWR fuels?

Taking into account the new context (predictable end of the US stock, possible emergence of new fuel and reactor concepts), the report has drawn a panorama of HALEU demand for the next decades.
Although there is great uncertainty because some of the research reactors are quite old and their replacement is only partly decided, we find that the world needs for HALEU could be around 3000 kg/yr for research reactors and radioisotopes.
If new concepts for reactors or fuels emerge, the quantity could rapidly increase by a factor of two or three already in the prototype phase.

It has also been concluded that the transport of UF6 at 19.75% between an enrichment facility and a metallisation facility, in particular between different countries, even for small quantities, will require the development and certification of a new protective shipping package (whose detailed assessment is beyond the scope of this study). For much larger quantities, a new container (and the corresponding protective shipping package) must be designed to accommodate higher volumes.

These casks haven't even been developed, so they could be some time off but may not be required anyway until around 2028 or thereabouts?

To estimate the economic feasibility of building a facility in Europe, three scenarios have been proposed to the industrial partners. They independently assess the possibility of producing 800 kg/ yr, 1500 kg/yr and 3000 kg/yr at a targeted price of €20 k/kg.
(that's US$2,2163 per Kg)

3000 X US$22163 =US$ 66,489,000 that is just for the research reactors and could possibly increase by a factor of two or three? is this just for testing the fuels for commercial use or does it include military use as well?

I believe that it doesn't include the HALEU that would be required for the existing LWR's in the very near future, which would require considerably more enriched Uranium but less enriched, possibly to around 10% not the full 19.75% required for the test reactors?
Would this mean that the cost of a 10% HALEU fuel for LWR's would be slightly less than half the cost of producing the 19.75% version for these test reactors? I believe they said it would be directly related to the cost of 5% enrichment, so double for 10% and nearly four times that for the highest grade 19.75% enrichment, the fuel cladding could be less for the 10% stuff possibly though but possibly more than what they use now for 5% fuel for LWR use?
