Senate to consider Matthew Marzano’s NRC nomination this week
The U.S. Senate’s Committee on Environment and Public Works will consider the nomination of Matthew Marzano to the Nuclear Regulatory Commission during a hearing on Wednesday, September 11.
In July, President Joe Biden named Marzano as his choice to fill the open seat on the five-member commission. The NRC, the nation’s independent regulator of civilian nuclear safety, has been without a tie-breaker for votes among the four current members since commissioner Jeff Baran’s term ended in June 2023.
The NRC has been in the spotlight in recent years as the United States experiences a resurgence in demand for and technology advances in nuclear power. The commission is facing a high volume of license requests and is working to modernize and streamline its review process.

Since the earlier liquid-metal fast breeder reactor transient overpower assessments were done (1975), new experimental data and modeling improvements have occurred that indicate later failures and more molten fuel squirted into the channel with a higher propensity for plugging. An initial sweepout still occurs, and an analysis shows that even if coherent instead of the expected stochastic failures occur, the blockages are partial, the reactor is strongly shut down, and a coolable geometry exists. Hence, the overall consequences would be benign.
