The nuclear industry’s first 100 percent accident tolerant fuel assembly has successfully completed its initial cycle of operation at a U.S. nuclear power plant, Framatome announced earlier this week.

Following 24 months of operation at Constellation Energy’s two-unit Calvert Cliffs nuclear power plant in Lusby, Md., testing and inspections confirm that Framatome’s lead Enhanced Accident Tolerant Fuel (EATF) assembly safely withstood in-reactor conditions and performed as designed, according to the French-based company.

"The accelerated delivery and proven performance of our technology reflects the dedication and expertise of our people with the collaborative support from the industry,” said Lionel Gaiffe, senior executive vice president of Framatome’s fuel business unit. “Collectively, we are one step closer in the qualification of our Protect EATF technology for the nuclear industry. With the adoption and implementation of our enhanced technologies, our industry partners continue to demonstrate their commitment to enhance the safety and performance of their reliable, low-carbon, energy operations.”

The comfort of nuclear power

July 27, 2023, 12:00PMNuclear NewsJames Conca

I am lucky. I live near a nuclear power plant—arguably the best run and most beautiful power plant in the world. It’s comforting.

It’s comforting to see Columbia Generating Station’s clean white plume of pure steam rise into the air every time I leave my house. Every time I’m driving home. Every time it’s freezing outside. Every time it’s scorching hot.

Even the few times when it has gone quiet for refueling, the plant stands like a Norman castle protecting the region from energy poverty. It’s comforting.

The Japanese government has chosen Mitsubishi Heavy Industries (MHI) to head up the conceptual design and research and development of a demonstration sodium-cooled fast reactor, the Tokyo-based engineering firm announced recently.

MHI is to oversee the work in partnership with Mitsubishi FBR Systems Inc. (MFBR), an MHI Group engineering company established in 2007 to develop and design fast breeder reactors.

Conceptual design work is scheduled to commence in fiscal year 2024, with operation of the unit slated for the 2040s.

Reactor roadmap: According to MHI’s announcement, in the strategic roadmap for fast-reactor development adopted by the Japanese Cabinet in December 2018, a policy was defined to assess the efficacy of several types of technologies to be developed following a competition among private-sector companies. The roadmap was subsequently revised by the Cabinet in December 2022, at which time two decisions were made: (1) to select a sodium-cooled fast reactor as the target of the conceptual design of the demonstration unit and (2) to select a manufacturer to serve as the core company in charge of the reactor’s design and requisite R&D.

ORNL’s Spallation Neutron Source reaches 1.7-MW power level

The Spallation Neutron Source (SNS) at the Department of Energy's Oak Ridge National Laboratory set a world record when its particle accelerator beam operating power reached 1.7 MW, an improvement on the facility’s original design capability of 1.4 MW, ORNL announced on July 21. That higher power provides more neutrons for researchers who use the Office of Science user facility for materials science investigations.

Gas-cooled reactors have roots that reach way back to the development of early experimental reactors in the United States and Europe. In the United States, early experimental reactors at Oak Ridge and Brookhaven National Laboratories were air-cooled, as were early production reactors known as the “Windscale Piles” in the United Kingdom. Dragon, also located in the United Kingdon and operational from 1965 to 1976, used helium as the coolant and graphite as the moderator.

What is at the forefront of PRA today?

July 20, 2023, 3:00PMNuclear NewsAskin Guler Yigitoglu

Probabilistic risk assessment is a mature technology that has benefited the safety of the current fleet of light water reactors in the United States since the 1970s. Most utilities have used PRA models as part of risk-informed in-service inspection programs to identify degraded plant conditions for more than two decades. The trends indicate an increasing use of risk-informed applications to support safe and cost-effective long-term operations.

Data science and predictive analytics innovations offer the opportunity to assess, monitor, and manage risk effectively. PRA models are coupled with digital twins informed by sensors and system simulators that provide real-time risk insights. Dynamic PRA approaches were initially introduced to beyond-design-basis event models for LWRs and explicitly model time-dependent operator behavior by simulating the actual plant response. Enhancing the quantification speed and memory usage of the PRA computational tools (both dynamic and traditional) is crucial for future risk-informed efforts.
