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).”

A method for calculating the depletion and production of uranium, plutonium, transplutonium nuclides, and fission products (DPUFP) in a boiling water reactor was evaluated using measured values for JPDR-1 nuclear fuel. The results show that (a) a three-dimensional nuclear thermohydrodynamic calculation is required for an accurate estimate, (b) the void fraction of a fuel assembly has a large effect on the production of transplutonium nuclides, (c) the measured values can be applied universally by correcting the irradiation and cooling histories and the effect of the neutron spectrum, (d) more reliable DPUFPs are obtained by closely correlating the calculated value of 134Cs/137Cs with the measured values, and (e) the effective neutron cross sections of uranium and plutonium can be obtained using the measured values.
