Former NRC commissioners lend support to efforts to eliminate mandatory hearings
A group of nine former nuclear regulatory commissioners sent a letter Wednesday to the current Nuclear Regulatory Commission members lending support to efforts to get rid of mandatory hearings in the licensing process, which should speed up the process by three to six months and save millions of dollars.

The once-through mode of steam generator reflux condensation in the presence of noncondensable gases and/or aerosols in loss-of-coolant accident scenarios is introduced. The plausible severe accident scenarios associated with once-through reflux condensation are analyzed with MELCOR to demonstrate the background and safety significance of this phenomenon. An analytical model for once-through reflux condensation with noncondensables inside one single U-tube is developed using the heat and mass transfer analogy approach. The conditions for partial condensation inside the single U-tube can be determined with this model. The progress of modification to the ARTIST test facility to experimentally study the tube-to-tube nonuniform behavior of once-through reflux condensation inside a U-tube bundle is reported.
