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 party-line 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.

The plutonium inventory control (PINC) system is a real-time material accountability control system that is expected to be applied to a new large-scale plutonium fuel production facility for both fast breeder reactor and heavy water reactor at the Power Reactor and Nuclear Development Corporation. The PINC is basically a system for material control but is expected to develop into a whole facility control system, including criticality control, process control, quality control, facility protection, and so forth. Under PINC, every process and storage area is divided into a unit area, which is the smallest unit for both accountability and process control. Item and material weight automatically are accounted for at every unit area, and data are simultaneously treated by a computer network system. Sensors necessary for the system are being developed.
