【 摘 要 】

UB2 -U3Si2 composite fuel pellets have been manufactured and characterised. Both main phases were observed to be stable in contact with one-another up to the maximum processing temperature of 1500 degrees C. The solubility and behaviour of hydrogen in UB2 was predicted and compared to previous work on the gas' behaviour in U3Si2. H-2 was found to be insoluble in UB2 to any great extent, a clear distinction to the behaviour with U3Si2. (C) 2019 Elsevier B.V. All rights reserved.
