Because of its hardness and its hardiness in the face of high temperatures, silicon carbide has been used for industrial purposes for decades. It has proven its worth as a key component of tiny TRISO fuel particles. But SiC has a weakness—in its pure form it is too brittle for use in structural components, such as 12-foot-long light water reactor fuel cladding tubes.

Latest electricity cost estimates get new details on nuclear

July 1, 2024, 12:00PMNuclear News

Every year, the National Renewable Energy Laboratory (NREL) puts out a set of technology-specific cost and performance parameters for electricity generation. Now in its 10th year, the Electricity Annual Technology Baseline (ATB) has nearly 100,000 users from 144 countries, according to NREL. Utility planners and grid operators who look to the ATB to assess their investment options in a changing market require complete and accurate information and will be glad to know that the 2024 Electricity ATB, released June 24, includes—for the first time—a range of data on nuclear energy.

With $3.4 billion to spend, the DOE opens RFP for low-enriched uranium

June 28, 2024, 12:01PMNuclear News

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.

ANS Annual Conference: Nuclear waste

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.

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 future has more in store for nuclear

Big news as I write this, my last column as ANS president: Legislation has been passed that will ban the importation of uranium from Russia (though waivers can be used in certain circumstances to continue imports through 2027). This ban has been discussed since the Russian invasion of Ukraine. I am sure all U.S. utilities have followed their risk-management policies.

With two years to plan, appropriate-use waivers, and access to American Assured Fuel Supply, there should not be any disruption to domestic reactor operations. The ban will force the United States and our Western allies to be independent and stronger. Congress has helped by providing $2.72 billion to support new domestic enrichment capacity. The challenge now is for the Department of Energy to turn this into actual new capacity as quickly as possible.

DOE ready to consider Russian U ban waivers

May 29, 2024, 7:01AMNuclear News

Utilities need to know months ahead of a scheduled refueling outage that fresh fuel will be on-site and ready to load. Now that the Prohibiting Russian Uranium Imports Act has been signed into law, U.S. utilities with plans to use Russian-origin low-enriched uranium also need to know if they can secure a waiver for imports through December 31, 2027—subject to specific annual limits—if “no alternative viable source of [LEU] is available to sustain the continued operation of a nuclear reactor or a United States nuclear energy company” or if LEU imports from Russia are “in the national interest.”
