Marzano sworn in as NRC commissioner
Marzano
Matthew Marzano became the newest member of the Nuclear Regulatory Commission when he was officially sworn into office by chair Christopher Hanson this week.
The nuclear engineer and former reactor operator was confirmed last month in a 50–45 vote in the U.S. Senate. Last July, President Biden nominated Marzano to serve on the commission, which is tasked with formulating policies, developing regulations, issuing orders, and resolving legal matters.
Marzano’s term expires June 30, 2028.

To reduce the cost of fast breeder reactor plants, advanced subsystem concepts are studied. The material quantities of the fuel handling system constituent subsystems are estimated and those with the largest quantities are selected for improvement. The advanced subsystem concepts studied include in-vessel fuel storage while cooling, an in-vessel fuel transfer machine with variable-reach arm, and a halfswing hinged-track fuel transfer machine. A significant reduction of overall system material quantity is promised by a suitable combination of the proposed advanced concepts.
