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).”

Alternating current (ac) tokamak operation in the reactor parameter range is studied by considering the volt-second consumption, A simple condition for obtaining ac operation with nearly constant pulse length is given by Lp/Rp < Td, ss (Lp is the plasma inductance, Rp is the plasma resistance, and Td, ss is the discharge length in the standard operation), assuming time-independent plasma parameters. The discharge length for ac operation is shorter than for standard operation and is given by where is the total transformer flux and is the plasma inductive flux. Alternating current operation is found to be advantageous in a large reactor having a large ohmic transformer flux satisfying . The superconducting magnetic energy storage system is proposed as an attractive power supply for ac operation in a large reactor.
