That hydrogen buildup was the result of hot steam coming into contact with overheated nuclear fuel rods covered by a cladding of zirconium alloy, or «zircaloy» — the material used as fuel - rod cladding in all water - cooled nuclear reactors, which constitute more than 90 percent of the world's power reactors.

There are still further tests to be done: In particular, while zircaloy tubes can have their ends capped by welding a metal disk onto each end, ceramic can't be welded, so a suitable bonding agent will need to be found.

While zircaloy loses strength as temperature increases — becoming 2 percent weaker for every 10 C increase in temperature and losing all strength at about 1300 C, Stempien says — the strength of the SiC ceramic remains essentially constant to temperatures well above 1500 C.

It utilizes the same 10 x 10 lattice design used in GNF2, and employs GNF's NSF (1.0 % niobium - 1.0 % tin - 0.35 % iron) zirconium alloy channel material which GNF says significantly reduces fuel channel distortion compared to typical zircaloy based channel materials.
