The Department of Energy bills Genesis as an AI push for scientific discovery. Its first public challenges tell a different story

Bob Mumgaard is an engineer and entrepreneur who co-founded Commonwealth Fusion Systems and serves as its chief executive officer. Trained in applied plasma physics at the Massachusetts Institute of Technology, he has worked on fusion energy technologies and efforts to commercialize fusion power.

Get the facts before the next big nuclear power debate: this is how safe nuclear power is.

Nuclear energy is among the world’s most debated power sources. It produces massive amounts of electricity without burning fossil fuels, yet safety and waste concerns persist. Understanding the advantages and disadvantages of nuclear energy helps provide an informed perspective on its role in addressing climate change and meeting global energy demands. How Nuclear Energy Works […] The post Nuclea…

This paper evaluates the neutronic feasibility and multi-physics safety of a hybrid Accident Tolerant Fuel (ATF) assembly in a VVER-1000 reactor. The proposed design strategically employs standard UO2 within the inner core and a high-density U3Si2 matrix in the peripheral pins to take advantage of inter-assembly thermalization for cycle length extension. Coupled evaluations were performed using O…

Industrial gamma radiography is a widely used non-destructive testing (NDT) technique, but it involves significant radiological risks that require precise planning of shielding and safety distances. Current practices rely heavily on in-situ radiometric measurements, which are time-consuming and may increase unnecessary operator exposure during setup and verification stages. This work presents RAD…

The safe geological disposal of high-level radioactive waste requires a passive multi-barrier system. This paper describes the engineered barriers foreseen in the provisional Swiss repository concept, covering both design aspects as well as evidence for their long-term performance. Disposal canisters made of carbon steel will be used for the encapsulation of spent nuclear fuel and vitrified high-…

Researchers are busy developing the perfect new nuclear power solution. It has its strengths precisely where traditional nuclear power is weak.

Materials science professor Michael Tonks was elected a fellow of the American Nuclear Society, one of the organization's highest honors recognizing significant contributions to nuclear science and technology.

The reboot highlights a dire problem for the country's nuclear program. Japan is running out of space to store spent nuclear fuel and lacks plans for radioactive waste disposal.

I'd like to start a discussion/debate of nuclear power for the purpose of informing people about it. I am participating in a thread in another forum http://www.badastronomy.com/phpBB/viewtopic.php?t=9370 where we are discussing an article about Germany planning to phase out nuclear... Read more

Charles G. Goulding explains how the convergence of AI data center energy demands and advanced nuclear engineering has turned additive manufacturing into a critical pathway for securing lucrative Federal R&D Tax Credits. The post 3D Printing the Nuclear Renaissance: How Additive Manufacturing Fuels the AI Power Grid and R&D Credits appeared on Fabbaloo .

Small modular reactor startup NX Atomics has announced a partnership with Sciaky, to apply Sciaky’s Electron Beam Additive Manufacturing process, known as EBAM, to components for NX Atomics’ SMR platform.The collaboration aims to reduce both the upfront capital cost and operating cost of SMR deployment by producing nuclear components faster, at lower cost, and in…

Fusion startup Helion is racing to complete a power plant for Microsoft by 2028. A fresh infusion of cash should help with that.

Generating electricity via nuclear fission is a great idea, at least in principle. But the risk of nuclear meltdowns causing mass destruction and long-lasting contamination isn’t appealing. Luckily, a crop of companies are looking to solve this problem by creating subcritical nuclear reactors, which generate power without ever making runaway nuclear reactions possible. Let’s take a look.

Helion Energy, a startup racing to commercialize fusion power, announced $465 million in new funding Thursday, bringing its total capital… Read More
