SOFIA (Reuters) – Bulgaria will consider using U.S. technology for a new nuclear reactor it wants to build at the country’s 2,000 megawatt Kozloduy nuclear power plant, Prime Minister Boyko Borissov said on Tuesday.

Borissov said the Balkan country was looking to diversify its nuclear energy assets and cut greenhouse emissions by building a new reactor based on modern technology that will work with U.S. nuclear energy fuel.

The government is expected to give its nod on Wednesday to a study that will explore the options for building new nuclear assets at the Kozloduy site, the energy ministry said.

At present, Bulgaria operates two Soviet-made nuclear reactors, Unit 5 and Unit 6, at its Kozloduy plant and is seeking investors for

Threat from nuclear weapons and missiles has grown since Trump entered office

The situation presents a broader challenge to the United States. The administration has heralded an era of “great power competition” with China and Russia, resulting in a competitive buildup that arms-control advocates warn is risking a full-blown arms race.

Russia is developing nuclear-armed underwater drones, nuclear-powered cruise missiles and other destabilizing weapons designed to penetrate U.S. missile defenses. China is ramping up its missile force and building out its nuclear capabilities with new nuclear submarines. And the United States is modernizing its own arsenal, while adding low-yield nuclear warheads to submarines and enhancing missile defenses. All the while, Iran and North Korea are advancing as threats.

The result is an escalatory cycle that experts say is threatening decades of progress controlling the world’s most dangerous weapons. A recent report from the Center for Strategic and International Studies warned that the decline of U.S. global influence and the rise of regional

Scientists Are Now One Step Closer to a Nuclear Clock

From Popular Mechanics

Scientists have a new precise measurement they say could help them finally make a nuclear clock, rather than a simply atomic one.

☢️ You love nuclear. So do we. Let’s nerd out over nuclear together.

Physicists from Gutenberg Universitaet Mainz (JGU) and other German scientists used an extremely tiny instrument—a magnetic microcalorimeter named maXs30—to measure movement within the nucleus of the isotope thorium-229. The scientists super-cooled the detector to minus 273 degrees Celsius to measure the “miniscule temperature rise that occurs when a gamma-ray is absorbed,” according to the JGU press release.

Thorium-229 is special among isotopes because of the extremely low energy of its lowest excited state, meaning it’s the best candidate for a measurable standard that can be used to make a practical clock. This isn’t something you’ll put on your nightstand, or even something that will likely be used inside your local university’s advanced

America’s First Nuclear Fusion Reactor Could Go Online in 2025

In 2014, Lockheed Martin (NYSE: LMT) shocked the world with the announcement that it was building a nuclear fusion reactor and planned to have it online “in as little as ten years.” Five years later, Lockheed confirmed that it is still working on the project — but had made very little progress in nuclear fusion energy.

North Korea’s Huge New ICBM Casts Doubt on Trump’s ‘No Longer a Nuclear Threat’ Claim

North Korea showcased a series of new weapons at its 75th anniversary military parade marking the founding of the ruling Workers’ Party Saturday, including what South Korea officials say was a new intercontinental ballistic missile (ICBM).

North Korea showcased a new intercontinental ballistic missile (ICBM) Saturday as part of a military parade celebrating their Workers Party’s 75th anniversary.

North Korea has not broadcast a live military parade on television since 2017, when leader Kim Jong Un heightened U.S. tensions by showing off several large ICBMs. The country showed off its “new strategic weapon,” which analysts described as a much larger, liquid fuel ICBM complete with an 11 axle transporter erector launcher.

The first hint of the new weapon came earlier this week when South Korean officials relayed surveillance of thousands of North Korean soldiers in march formation as they displayed what was possibly a new

Without nuclear power, the world’s climate challenge will get a whole lot harder

The Covid-19 crisis not only delivered an unprecedented shock to the world economy. It also underscored the scale of the climate challenge we face: Even in the current deep recession, global carbon emissions remain unsustainable.

If the world is to meet energy security and climate goals, clean energy must be at the core of post-Covid-19 economic recovery efforts. Strong growth in wind and solar energy and in the use of electric cars gives us grounds for hope, as does the promise of emerging technologies like hydrogen and carbon capture. But the scale of the challenge means we cannot afford to exclude any

Scientists at St. Jude Children’s Research Hospital have visualized previously unknown structures of the ABL kinase, offering insight for designing the next generation of targeted therapies for adult and childhood cancers. The work will advance understanding of treatment resistance to targeted cancer therapies. The findings appear as an advance online publication today in Science.

Central to this achievement was the United States’ most powerful nuclear magnetic resonance (NMR) spectrometer, which was installed at St. Jude in 2019. Just as microscopes enable scientists to peer inside a cell, NMR spectroscopy lets researchers visualize previously invisible, or undetectable, molecular structures that cannot be seen with other

US military eyes nuclear thermal rocket for missions in Earth-moon space

The U.S. military aims to get a nuclear thermal rocket up and running, to boost its ability to monitor the goings-on in Earth-moon space.

The Defense Advanced Research Projects Agency (DARPA) just awarded a $14 million task order to Gryphon Technologies, a company in Washington, D.C., that provides engineering and technical solutions to national security organizations.

The money will support DARPA’s Demonstration Rocket for Agile Cislunar Operations (DRACO) program, whose main goal is to demonstrate a nuclear thermal propulsion (NTP) system in Earth orbit.

NTP systems use fission reactors to heat propellants such as hydrogen to extreme temperatures, then eject the gas through nozzles to create thrust. This tech boasts a thrust-to-weight ratio about 10,000 times higher than that of electric propulsion systems and a specific impulse, or propellant efficiency, two to five times that of traditional chemical rockets, DARPA officials wrote in a

Small Nuclear Reactor Pilot Program: NuScale Tiny Reactor Project

  • Two of 35 cities have opted out of a pilot nuclear plant program powered by NuScale.
  • NuScale’s tiny modular reactors will be manufactured at Idaho National Laboratory.
  • Time will tell if these two opt-outs hold larger meaning for NuScale’s ambitious plans.

    Small modular reactor startup NuScale had a setback this week when two cities pulled out of a planned 35-city pilot program of new nuclear plants. As the first small reactor to break through many regulatory landmarks, NuScale has been under a great deal of public scrutiny. Is this a bump in the road or something more? That’s a question of perspective.

    ☢️ You like nuclear. So do we. Let’s nerd out over nuclear together.
