NuScale modular nuclear reactors can produce over 2,000 kg/hour of hydrogen

Posted by in categories: economics, nuclear energy

NuScale Power, the startup specializing in the design of small modular nuclear reactors, has published new data concerning the production capacities of its NuScale Power Module (NPM). Thanks to the 25% increase in power output of an NPM, each NuScale module is now capable of producing 2,053 kg/hour of hydrogen, or nearly 50 metric tons per day.

Just one NuScale Power Module can produce 77 MWe of carbon-free electricity to power 60,000 homes in the U.S. NuScale’s flagship power plant design can house up to 12 modules for a total gross output of 924 MWe. The 924 MWe that a 12-module NuScale plant produces is enough to power nearly 700,000 homes with clean, reliable energy.

US achieves laser-fusion record: what it means for nuclear-weapons research

Posted by in categories: military, nuclear energy, physics

Housed at Lawrence Livermore National Laboratory, the US$3.5-billion facility wasn’t designed to serve as a power-plant prototype, however, but rather to probe fusion reactions at the heart of thermonuclear weapons. After the United States banned underground nuclear testing at the end of the cold war in 1,992 the energy department proposed the NIF as part of a larger science-based Stockpile Stewardship Program, designed to verify the reliability of the country’s nuclear weapons without detonating any of them.

With this month’s laser-fusion breakthrough, scientists are cautiously optimistic that the NIF might live up to its promise, helping physicists to better understand the initiation of nuclear fusion — and thus the detonation of nuclear weapons. “That’s really the scientific question for us at the moment,” says Mark Herrmann, Livermore’s deputy director for fundamental weapons physics. “Where can we go? How much further can we go?”

Here Nature looks at the NIF’s long journey, what the advance means for the energy department’s stewardship programme and what lies ahead.

What is a floating nuclear power plant?

Posted by in categories: nuclear energy, robotics/AI, sustainability

A floating nuclear power plant is a site with one or more nuclear reactors, located on a platform at sea.

It is an autonomous site that can provide electricity and heat to areas with difficult access, such as the cold Northern territories. It can also provide drinking water to dry areas, via desalination techniques.

‘A combination of failures:’ why 3.6m pounds of nuclear waste is buried under a popular California beach

Posted by in categories: materials, nuclear energy

You may not want to live near areas like this in the country.

“The problem you have here is that the NRC is simply not doing its job as a regulator. So what it has done is allowed the industry to basically determine the conditions under which this material is stored on a temporary basis across the country,” echoed retired Rear Admiral Len Hering, who served more than 30 years in the US navy and was awarded a2005presidential award for leadership in federal energy management from President George W Bush.

Fusion breakthrough: 70% yield from input energy

Posted by in categories: climatology, nuclear energy

The National Ignition Facility (NIF) in California has achieved a major breakthrough in the quest to develop nuclear fusion power.

The NIF is the world’s largest inertial confinement fusion (ICF) device and contains the world’s largest laser. Its 192 beams are housed in a 10-story building the size of three football fields. When combined, these can generate over a million joules of energy, or about 0.1% the amount of a lightning bolt.

Scientists have been using the immense power of this laser to heat small capsules of deuterium and tritium (isotopes of hydrogen) in an effort to reach “ignition” and kickstart thermonuclear fusion. This process, the same reaction that powers our Sun, could one day provide a limitless source of clean energy.

Could We Explore the Entire Galaxy With Self-Replicating Robots?

Posted by in categories: 3D printing, environmental, nuclear energy, physics, robotics/AI, solar power, space, sustainability

Circa 2016


Scientists and engineers since the 1940s have been toying with the idea of building self-replicating machines, or von Neumann machines, named for John von Neumann. With recent advances in 3D printing (including in zero gravity) and machine learning AI, it seems like self-replicating machines are much more feasible today. In the 21st century, a tantalizing possibility for this technology has emerged: sending a space probe out to a different star system, having it mine resources to make a copy of itself, and then launching that one to yet another star system, and on and on and on.

As a wild new episode of PBS’s YouTube series Space Time suggests, if we could send a von Neumann probe to another star system—likely Alpha Centauri, the closest to us at about 4.4 light years away—then that autonomous spaceship could land on a rocky planet, asteroid, or moon and start building a factory. (Of course, it’d probably need a nuclear fusion drive, something we still need to develop.)
