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.

The installed defueling water cleanup system filters experienced severely reduced operating life. This was caused by blinding of the filter media due to colloidal material located within the Three Mile Island Unit 2 (TMI-2) reactor vessel. Through laboratory testing, a combination of coagulant and filter aid placed on the filter media was found to extend operating time tenfold. A system of pumps, mixers, tank, and control was developed to apply the coagulant and filter aid to the filters located in the TMI-2 damaged containment.
