MANUFACTURE OF GRANULAR URANIUM CONTAINING MATERIAL

Patent ·
OSTI ID:4079874

Normally, when an aqueous solution of uranyl nitrate is neutralized by ammonia and precipitated with urea, granular uranium dioxide is obtained; the size of the grains, however, is not homogeneous. The following conditions have to be fulfilled: concentration of urea = 110 to 220 grams per liter, temperature of the solution = 90 to 98 deg C, and initial concentration of nitrate ions below 1.8 iongram per liter. The obtained precipitate is amorphous and can be eventually reduced into uranium dioxide by hydrogen. (EURATOM)
