Constellation Energy is in talks with the governor’s office and state legislators about funding to restart a unit at Three Mile Island nuclear plant, Reuters has reported. The ongoing talks have been described as “beyond preliminary” by two sources.

An external radiation monitoring station was taken out by shelling and fire near the Zaporizhzhia nuclear plant in Ukraine the last week of June.
This brings the total to four of the plant’s 14 radiation monitoring sites that are out of commission, further reducing the effectiveness of its off-site capability to detect and measure any radioactive release during an emergency, said IAEA director general Rafael Mariano Grossi.

Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

With increasing demand for clean, reliable, and safe sources of energy, the conversation around nuclear energy is changing. And so too is the conversation around nuclear waste, even as the country struggles to find a path for the disposal of its spent nuclear fuel and high-level radioactive waste. From community engagement, to recycling, to existing success around other forms of nuclear waste management, the conversation around nuclear waste has many different angles, and an executive session of the American Nuclear Society’s 2024 Annual Conference in Las Vegas aimed to delve into some of those discussions.

Regardless of how you power our grid or how you attempt to decarbonize our economy, we will need many various metals to achieve any future, or even to just continue with business as usual. Critical metals like cobalt, lithium, nickel, and neodymium are essential to a low-carbon-energy future if renewables and electric vehicles are to play a large role.1 Even if nuclear provides 100 percent of our power, just operating the grid and electrifying most sectors will take huge amounts of critical metals like copper, notwithstanding the fact that nuclear power requires the least amount of metals and other materials of any energy source.

Researchers at the Department of Energy’s Oak Ridge National Laboratory want to make the sensors in nuclear power plants more accurate by linking them to electronics that can withstand the intense radiation inside a reactor. Electronics containing transistors made with gallium nitride, a wide-bandgap semiconductor, have been tested in the ionizing radiation environment of space. Now, according to a June 24 article from ORNL, tests carried out in the research reactor at Ohio State University indicate they could withstand neutron bombardment within a nuclear fission reactor.

The Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) announced June 20 that two companies—one power plant operator and one advanced reactor developer—are getting vouchers to access the extensive nuclear research capabilities and expertise available across the DOE national laboratories in the third round of GAIN vouchers awarded for fiscal year 2024.

Earlier this month, nearly 250 personnel at the Department of Energy’s Savannah River Site in South Carolina took part in an annual exercise to test preparedness for a radiological release and contamination emergency.

Natura Resources, which is supporting the construction of a molten salt research reactor on the campus of Texas’s Abilene Christian University, announced in mid-June that it expects the Nuclear Regulatory Commission to complete its safety assessment and issue a permit for the nonpower test reactor in September.
