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.

The Department of Energy released an anticipated request for proposals on June 27 for low-enriched uranium enrichment. “Today’s action will help spur the safe and responsible build-out of uranium enrichment capacity in the United States, promote diversity in the market, and provide a reliable supply of commercial nuclear fuel to support the energy security and resilience of the American people and domestic industries, free from Russian influence,” the DOE declared.

The Department of Energy’s Office of Environmental Management awarded a 10-year contract worth up to $630 million to Louisiana-based Aptim Federal Services for deactivation and decommissioning work at two U.S. Naval Nuclear Propulsion Program sites in New York.

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.

It was a summer day in 1956 in Berkeley, Calif., when I, a freshly minted Ph.D., left Lawrence Livermore National Laboratory to travel to Pittsburgh, Pa., to join Westinghouse’s Commercial Atomic Power (CAPA) program. We were going to develop a large homogeneous power reactor—the future of energy. A year later, my efforts were diverted to lead what may have been one of the first nuclear safeguards equipment development programs funded by the Atomic Energy Commission.

In May’s Nuclear News (p. 86), we reviewed Argonne National Laboratory’s comprehensive work on fast reactors in Idaho. In this article, we summarize the light water reactor work there.¹

In the early days, there were few data on the behavior of reactor materials under severe neutron bombardment. In collaboration, Oak Ridge National Laboratory and Argonne National Laboratory developed the Materials Testing Reactor (MTR) for the National Reactor Testing Station (NRTS) in Idaho. The materials tested in it over the course of 15,000 experiments were reactor fuel materials, structures, cooling systems, and shields. It operated from 1952 to 1970.

The National Nuclear Security Administration’s Office of Defense Nuclear Nonproliferation has awarded a total of $50 million in cooperative agreements to the Consortium for Enabling Technologies and Innovation and the Enabling Capabilities in Technology Consortium. These two university/national lab consortia are each to receive as much as $5 million per year for five years to help support their basic and applied science research, which, in turn, will support the nuclear security and nonproliferation missions of the NNSA and workforce development for the Department of Energy’s national laboratories.

Innovations with small modular reactors, which offer a compact, efficient alternative to traditional baseload power plants, are at the forefront of a new era of nuclear energy production that can reshape how we approach industrial decarbonization.

As global energy transition efforts progress, it is essential to examine the potential these advancements hold for reducing carbon emissions. Nuclear energy has long been recognized for its ability to generate vast amounts of electricity without emitting greenhouse gases. The introduction of SMR technology represents a pivotal shift, addressing many previous challenges to nuclear deployment and opening new pathways for the integration of nuclear energy into industrial sectors.

The innovative yet simple design of NuScale’s SMR technology provides a cost-competitive, safe, and scalable solution for a wide range of energy needs.

Dutton

The only nuclear reactor in Australia is a small one in the Sydney suburb of Lucas Heights, which has been used to produce medical radioisotopes since 1958. Recently, the Hon. Peter Dutton, Parliament’s leader of the opposition to the Labor-led government, announced his plan to get the country into the nuclear energy business by building five large reactors and two small modular reactors by 2050.

Criticizing the government’s “renewables-only” energy policy, Dutton promised to have the first nuclear reactor operating by the mid-2030s, should his Liberal–National Coalition win power in the next federal election (to be held on or before September 27, 2025). That promise, which would require overturns of existing federal and state bans on nuclear energy, has generated a great deal of controversy in Australia among government officials, political activists, and nuclear engineers.

ANSI/ASME/ANS RA-S-1.2-2024, Severe Accident Progression and Radiological Release (Level 2) PRA Standard for Nuclear Power Plant Applications for Light Water Reactors (LWRs), received the approval of the American National Standards Institute (ANSI) on May 31, 2024, and was issued on June 17, 2024.

ANSI/ASME/ANS RA-S-1.2-2024 is available in the ANS Online Store.

At the 34th ITER Council Meeting, held June 19–20, ITER director general Pietro Barabaschi reported on ITER’s progress and presented an updated baseline proposal that would “prioritize the start of substantial research operations as rapidly as possible.”

Industry leaders met this week to discuss the importance of shoring up nontraditional workforce pipelines to support growth in nuclear energy generation in the coming decades.

An executive panel discussed this issue last week at the American Nuclear Society’s 2024 Annual Conference in Las Vegas The industry is working to target community colleges, trade schools, vocational programs, nontraditional students, and a wider variety of educational backgrounds.

The Department of Energy’s Office of Environmental Management announced that it has completed construction of the new large-scale ventilation system at its Waste Isolation Pilot Plant in New Mexico.

The American Nuclear Society brought together 11 other energy and environmental advocacy organizations in calling on Congress to fund the Environmental Protection Agency to develop a new, technology-neutral, generic environmental standard for the disposal of spent nuclear fuel and high-level radioactive waste in the United States.

In a letter to the leaders of the House and Senate appropriations committees, the groups ask for an additional $3 million in fiscal year 2025 for the EPA’s Office of Radiation and Indoor Air to work on the new standard.

Christensen

The conversation was casual with John Christensen, president and chief executive officer of Utilities Service Alliance, as he reflected on his 17 years with the organization. Christensen will be stepping down from USA to retire at the end of the year. He will be succeeded as president and CEO/managing director by Karen Fili, most recently with Urenco USA.

USA is a nonprofit organization incorporated in 1996 to provide its utility and nonutility members a business platform to collaborate on plant performance and economic benefit initiatives. Currently, USA members include 39 nuclear reactors (and one uranium enrichment plant) that provide more than 39,650 MWe of generation. As Christensen explained, USA members get the best of both worlds: the fleet benefits by working with USA while keeping the flexibility of independent operator status.
