Researchers at Sandia National Laboratories have been expanding MELCOR—the severe accident modeling computer code used by the Nuclear Regulatory Commission to evaluate the safety of light water reactors—to study the small modular reactors and non-light-water advanced reactors that are under development. An article published in Sandia Lab News on August 27 describes in detail how MELCOR is being expanded to work with different reactor geometries, fuel types, and coolant systems.

A federal court last week sided with the Tennessee Valley Authority in its legal dispute with Nuclear Development LLC over the proposed sale of the unfinished Bellefonte nuclear power plant. The court, however, also ordered the utility to refund millions to Nuclear Development over the aborted transaction.

The Emirates Nuclear Energy Corporation has announced the startup of Unit 2 at the Barakah nuclear power plant, located in the Al Dhafra region of Abu Dhabi, the United Arab Emirates’ capital city.
The milestone, ENEC noted in its August 27 announcement, was achieved approximately one year after the startup of the plant’s Unit 1 reactor and within five months of Unit 1’s entering commercial operation.

NorthStar Medical Technologies of Beloit, Wis., will receive $37 million under two cooperative agreements with the National Nuclear Security Administration for the production of molybdenum-99 without the use of high-enriched uranium. Considered a critical medical radioisotope, Mo-99 is used in more than 40,000 medical procedures in the United States each day, including the diagnosis of heart disease and cancer.

A pronuclear think tank in Belgium has written a letter to the country’s prime minister, Alexander De Croo, urging him to reevaluate the government’s plan to phase out nuclear power generation by 2025 and replace it with gas power.
A new facility being built at the Advanced Photon Source will allow research into irradiated materials.
This rendering shows the Activated Materials Laboratory (AML), to be constructed as part of the Advanced Photon Source upgrade that includes the High-Energy X-ray Microscope (HEXM) and the In Situ Nanoprobe (ISN). This new facility will simplify the process of researching nuclear materials.

The lack of a specialized laboratory at Argonne National Laboratory’s Advanced Photon Source (APS) has slowed efforts to study irradiated materials at the facility. Things will change soon, however, with the addition of the new Activated Materials Laboratory that is planned to be built and operational by 2024.

Exelon Generation has received a grant from the Department of Energy to explore the potential benefits of on-site hydrogen production and has chosen its Nine Mile Point nuclear power plant as the demonstration site, the company announced on Wednesday. (In 2019, Exelon received a conditional commitment from the DOE to co-fund a hydrogen electrolyzer demonstration at a nuclear plant.) Located in Scriba, N.Y., Nine Mile Point consists of two boiling water reactors—the 620-MWe Unit 1 and the 1,287-MWe Unit 2.

At the box office or streaming at home, it’s fear, not truth, that sells. The laws of physics are swept aside, apocalypse is inevitable, and superpowered heroes wait until the last possible second to save the universe. It can make for great entertainment, but in the real world we need to stick with science over science fiction and be wowed by engineering, not special effects.
The truth is, science and innovation are incredible in their own right. From communications and machine learning to space travel and medical advances, technology is evolving in hyperdrive to solve real problems. With climate change and global warming here on earth, we don’t have to go looking for trouble in a galaxy far, far away.

NuScale Power has signed a memorandum of understanding with Xcel Energy to explore the feasibility of the utility’s serving as a plant operator at NuScale plants, the Portland, Ore.-based small modular reactor developer announced earlier this week.
Xcel owns and, through subsidiary Northern States Power Company, operates Minnesota’s two nuclear plants, Monticello and Prairie Island. The Monticello facility houses one 671-MWe boiling water reactor, while Prairie Island has twin 550-MWe pressurized water reactors.

Lawrence Livermore National Laboratory is celebrating the yield from an experiment at the National Ignition Facility (NIF) of more than 1.3 megajoules of energy—eight times more than the yield from experiments conducted this spring and 25 times more than NIF’s 2018 record yield.
