ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

Around 200 kg of (Pu0.55 U0.45)C fuel pellets of relatively low density (86 ± 2% theoretical density) would be used as a driver fuel in the second core of the Fast Breeder Test Reactor in India. The current paper summarizes the production experience of the initial 15 kg of these fuel pellets following the “vacuum carbothermic synthesis” of tableted oxide-graphite powder mixture followed by “cold-pelletization” of carbide powder and “sintering.” The alterations made in the process equipment, radiation shielding arrangements, and fabrication parameters have been highlighted. The carbothermic synthesis and sintering were carried out in batches of 600 g and 1 kg, respectively. The percentage recovery of sintered pellets in all the batches was >90%. The resintering tests of pellets showed only marginal change in sintered density, ensuring minimum in-pile densification.
