Southern Company is targeting December for placing Vogtle-3 in service, according to Tom Fanning, the company’s chairman, president, and chief executive officer, who spoke with financial analysts on April 29 in its first-quarter earnings call. “The site work plan now targets fuel load in the third quarter and late December 2021 in-service date for Unit 3,” Fanning said. “Of course, any delays could result in a first-quarter 2022 Unit 3 in-service date.”

Climate activists rarely mention nuclear power as a tool in the battle against climate change, consumer reporter John Stossel comments during the video "The Nuclear Option" on his YouTube channel.

Completing a 5,700-mile journey from Belgium, two 24-ton particle accelerators were delivered to NorthStar Medical Radioisotopes’ facility in Beloit, Wis., on April 22, the Wisconsin State Journal reported. Photos and a video of the accelerators being received at the facility are included in the report.

On April 26, 1986, reactor No. 4 of the Chernobyl nuclear power plant in Ukraine exploded, sending radioactive material into the environment and across Europe. After 35 years, Ukrainians are looking to the site of the world’s worst nuclear disaster “for inspiration, solace, and income,” according to an ABC News report.

The Department of Energy’s Richland Operations Office contractors Central Plateau Cleanup Company (CPCCo) and Hanford Mission Integration Solutions (HMIS) teamed up recently to dive into inspection and maintenance activities at the Hanford Site in Washington state.

Comparing matter to a “lush tapestry, woven from a complex assortment of threads,” physics writer Emily Conover traces the evolution of our understanding of the atom over the past century in the recent Science News article, “How matter’s hidden complexity unleashed the power of nuclear physics.” Conover uncovers how our vision of matter changed from that of a “no-nonsense plaid” to one of an “ornate brocade,” ultimately transforming nuclear physics from an arcane academic pursuit to something that forever changed the world.
The Indian Point nuclear power plant
With a blunt but indisputably accurate headline, an article from yesterday’s New York Times on the imminent closure of Indian Point makes it immediately clear what will happen when Unit 3, the nuclear plant’s last operating reactor, is shut down at the end of this month: The state of New York will be forced to rely more heavily on fossil fuels for electricity generation.
Following the retirement of Indian Point-2 last April, the share of New York’s power coming from gas-fired plants rose to about 40 percent, from about 36 percent in 2019, the piece notes, adding that the share from renewables moved up only slightly, to about 30 percent.
In this illustration of the effects of two neutron yields (50 kt and 1 Mt) and two neutron energies (14.1 MeV and 1 MeV), the black dots represent the location of a nuclear device. Dark blue indicates where the asteroid remains solid, while all other colors show where material has been melted or vaporized. The illustration depicts asteroids with 0.8-m and 5-m diameters—much smaller than the 300-m asteroid simulated in the study—to enhance the visibility of the area of the energy deposition. Image: LLNL
A research collaboration between Lawrence Livermore National Laboratory and the Air Force Institute of Technology (AFIT) has investigated how the neutron energy generated by the detonation of a nuclear device could affect the path and speed of an asteroid on a collision course with Earth by melting and vaporizing a portion of the asteroid. The research, which compared the deflection caused by two different neutron energies—14.1 MeV and 1 MeV, representing fusion and fission neutrons, respectively—is described in an article published by LLNL on April 8.

Saying they are cautiously optimistic that the Biden administration can change the U.S. trajectory on nuclear waste, some Stanford University experts have offered their recommendations on how it can be done in a recent Stanford news posting.

Around the world, national and local policymakers and business leaders are making bold and ambitious commitments to clean energy goals. In the United States, one in three Americans now lives in a city or state that has committed to or has achieved 100 percent clean electricity, according to the Luskin Center for Innovation at the University of California–Los Angeles.

Research led by scientists at the Department of Energy's Princeton Plasma Physics Laboratory (PPPL) provides new evidence that particles of boron, the main ingredient in Borax household cleaner, can coat internal components of doughnut-shaped plasma devices known as tokamaks and improve the efficiency of the fusion reactions, according to an article published on Phys.org on April 2.
