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).”

The Japanese design of HFTM, so-called HFTM-H, aims to be used for high temperature irradiation test up to 1000°C for SiC/SiCf composite and refractory materials. During irradiation test periods in the IFMIF, irradiated materials must be maintained at constant temperatures. It is confirmed that the conceptual design of HFTM-H can satisfy the requirement for displacement per atom (dpa). The gas production rate to dpa ratio, which is important requirement for the design of HFTM-H as well as dpa is calculated. Nuclear heating distribution in HFTM-H is also predicted, which is served to temperature control design and structural analysis.
