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 high-conversion boiling water reactor (HCBWR) has been studied as one of the next-generation BWRs. The HCBWR can be improved by the use of island-type fuel, which has mixed-oxide rods in the bundle interior and uranium rods only in the small region of the periphery, to have inherently negative void coefficient (i.e., negative void coefficient in infinite lattice configuration). The proposed reactor concept also has the sustainability to extend the light water reactor's period by ~180 yr and the compatibility with a conventional BWR system such that only substitution of fuel bundles and control rods is required. As an example case, the high-conversion advanced boiling water reactor II (ABWR-II) is evaluated.
