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 behavior model for fission gas in irradiated liquid-metal fast breeder reactor fuels is applied in a computer code. The subroutine LANGZEIT calculates the “long-time” kinetics processes during steady-state operation. The results are used as initial conditions for the subroutine KURZZEIT, which permits the description of the bubble growth during rapid overpower transients. This model has been applied to the SNR-300-Mark I core. The calculations indicate a prompt precipitation of fission gas during the reactivity excursions, which results in a dampening effect on the reactivity ramps.
