SMRs are cheaper and quicker to build than traditional reactors, and can also be deployed in remote regions and on ships and aircraft. Their “modular” format means they can be shipped by container from the factory and installed relatively quickly on any proposed site.

SHANGHAI, July 13 (Reuters) — China has started construction of the first commercial onshore nuclear project using its homegrown “Linglong One” small modular reactor (SMR) design, the China National Nuclear Corporation (CNNC) said on Tuesday, about four years later than planned.

CNNC originally aimed to start building the project at the Changjiang nuclear reactor complex on the island province of Hainan in 2017, but it has been subject to regulatory delays.

The “Linglong One”, also known as the ACP100, was the first SMR to be approved by the International Atomic Energy Agency in 2016. Each unit has power generating capacity of 125 megawatts (MW).

Jacopo Buongiorno and others say factory-built microreactors trucked to usage sites could be a safe, efficient option for decarbonizing electricity systems.

We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon, they say.

These proposed systems could provide heat for industrial processes or electricity for a military base or a neighborhood, run unattended for five to 10 years, and then be trucked back to the factory for refurbishment. The authors — Jacopo Buongiorno, MIT’s TEPCO Professor of Nuclear Science and Engineering; Robert Frida, a founder of GenH; Steven Aumeier of the Idaho National Laboratory; and Kevin Chilton, retired commander of the U.S. Strategic Command — have dubbed these small power plants “nuclear batteries.” Because of their simplicity of operation, they could play a significant role in decarbonizing the world’s electricity systems to avert catastrophic climate change, the researchers say. MIT News asked Buongiorno to describe his group’s proposal.

Case in point, a subsidiary of Russia’s Roscosmos space agency is now proposing a nuclear power station on Mars, intended to power a future Russian base on the Red Planet, state-run news agency Sputnik reports.

The Arsenal Design Bureau, the subsidiary, is recommending using the same technologies destined for Zeus, a proposed interplanetary space tug, to power a nuclear reactor on the Martian surface as well.

The massive space tug is designed to make use of a nuclear-powered electric propulsion system to deliver payloads throughout the solar system. Earlier this year, Roscosmos chief Dmitry Rogozin suggested that Zeus could also visit other planets, including Jupiter, to search for alien life. Russia is hoping to begin flight-testing it starting around 2030.

Imagine a dust particle in a storm cloud, and you can get an idea of a neutron’s insignificance compared to the magnitude of the molecule it inhabits.

But just as a dust mote might affect a cloud’s track, a can influence the energy of its molecule despite being less than one-millionth its size. And now physicists at MIT and elsewhere have successfully measured a neutron’s tiny effect in a radioactive molecule.

The team has developed a new technique to produce and study short-lived radioactive molecules with neutron numbers they can precisely control. They hand-picked several isotopes of the same molecule, each with one more neutron than the next. When they measured each molecule’s energy, they were able to detect small, nearly imperceptible changes of the nuclear size, due to the effect of a single neutron.

In 1958, Ford showed the world a car like it had never seen before, one powered by a small nuclear reactor. The Ford Nucleon, as it was christened, was envisioned as a car capable of driving more than 5000 miles between fueling stops, appealing to a postwar fixation with convenience that has dominated American consumerism since. Like some other midcentury nuclear fantasies, though, the Nucleon never came to fruition, in part due to engineering problems we still struggle with to this day.

Before we examine why the Nucleon could never be, let’s get a better grasp of the car itself, starting with its utterly comical dimensions. Ford’s press materials envisaged the Nucleon stretching 200.3 inches long and 77.4 wide, making it as long as the new Ford Maverick compact pickup, but slightly wider. Its roof was said to measure just 41.4 inches high, making it less than an inch taller than the legendarily low-slung Ford GT40.

Experts are excited by the concept of microreactors because nuclear facilities have historically relied on economies of scale — a paradigm this tech could reverse.

“Microreactors promise to turn this paradigm on its head by approaching cost competitiveness through technological learning,” Alex Gilbert from the nuclear power think tank Nuclear Innovation Alliance, told CNBC.

Oklo’s “fast reactor” plant uses energy from already-spent nuclear reactor fuel, technology that has been around since the 1950s, according to CNBC.

Neil deGrasse Tyson explains the early state of our Universe. At the beginning of the universe, ordinary space and time developed out of a primeval state, where all matter and energy of the entire visible universe was contained in a hot, dense point called a gravitational singularity. A billionth the size of a nuclear particle.

While we can not imagine the entirety of the visible universe being a billion times smaller than a nuclear particle, that shouldn’t deter us from wondering about the early state of our universe. However, dealing with such extreme scales is immensely counter-intuitive and our evolved brains and senses have no capacity to grasp the depths of reality in the beginning of cosmic time. Therefore, scientists develop mathematical frameworks to describe the early universe.

Neil deGrasse Tyson also mentions that our senses are not necessarily the best tools to use in science when uncovering the mysteries of the Universe.

It is interesting to note that in the early Universe, high densities and heterogeneous conditions could have led sufficiently dense regions to undergo gravitational collapse, forming black holes. These types of Primordial black holes are hypothesized to have formed soon after the Big Bang. Going from one mystery to the next, some evidence suggests a possible Link Between Primordial Black Holes and Dark Matter.

In modern physics, antimatter is made up of elementary particles, each of which has the same mass as their corresponding matter counterparts — protons, neutrons and electrons — but the opposite charges and magnetic properties.

A collision between any particle and its anti-particle partner leads to their mutual annihilation, giving rise to various proportions of intense photons, gamma rays and neutrinos. The majority of the total energy of annihilation emerges in the form of ionizing radiation. If surrounding matter is present, the energy content of this radiation will be absorbed and converted into other forms of energy, such as heat or light. The amount of energy released is usually proportional to the total mass of the collided matter and antimatter, in accordance with Einstein’s mass–energy equivalence equation.

The artificial intelligence revolution is just getting started. But it is already transforming conflict. Militaries all the way from the superpowers to tiny states are seizing on autonomous weapons as essential to surviving the wars of the future. But this mounting arms-race dynamic could lead the world to dangerous places, with algorithms interacting so fast that they are beyond human control. Uncontrolled escalation, even wars that erupt without any human input at all.

DW maps out the future of autonomous warfare, based on conflicts we have already seen – and predictions from experts of what will come next.

## GENERAL FUSION (VANCOUVER) • JUN 16, 2021.

# General Fusion to build its Fusion Demonstration Plant in the UK, at the UKAEA Culham Campus.

*Unlike conventional nuclear power, which involves fission or splitting atoms, the emerging fusion technology promises clean energy where the only emission would be helium, and importantly, no radioactive waste.*

New partnership between General Fusion and UKAEA is a landmark collaboration in the development of fusion, a technology for the world’s low-carbon future.

VANCOUVER, Canada and LONDON, United Kingdom (17th June 2021 BST): The UK Atomic Energy Authority (UKAEA) and General Fusion have announced an agreement under which General Fusion will build and operate its Fusion Demonstration Plant (FDP) at UKAEA’s Culham Campus. General Fusion will enter into a long-term lease with UKAEA following construction of a new facility at Culham to host the FDP. The FDP will demonstrate General Fusion’s proprietary Magnetized Target Fusion (MTF) technology, paving the way for the company’s subsequent commercial pilot plant. General Fusion will benefit from the cluster of fusion supply chain activities in the UK, centered on UKAEA’s globally recognized expertise and presence in the field.

Amanda Solloway, Science Minister for UK Government said: “This new plant by General Fusion is a huge boost for our plans to develop a fusion industry in the UK, and I’m thrilled that Culham will be home to such a cutting-edge and potentially transformative project. Fusion energy has great potential as a source of limitless, low-carbon energy, and today’s announcement is a clear vote of confidence in the region and the UK’s status as a global science superpower.”

The Fusion Demonstration Plant at Culham is the culmination of more than a decade of advances in General Fusion’s technology, and represents a major milestone on the company’s path to commercialization. The Fusion Demonstration Plant will verify that General Fusion’s MTF technology can create fusion conditions in a practical and cost-effective manner at power plant relevant scales, as well as refine the economics of fusion energy production, leading to the subsequent design of a commercial fusion pilot plant. Construction is anticipated to begin in 2022, with operations beginning approximately three years later.

General Fusion and UKAEA intend to collaborate on a range of fusion energy technologies for power plant design and operation.

“Coming to Culham gives us the opportunity to benefit from UKAEA’s expertise,” stated Christofer Mowry, CEO, General Fusion. “By locating at this campus, General Fusion expands our market presence beyond North America into Europe, broadening our global network of government, institutional, and industrial partners. This is incredibly exciting news for not only General Fusion, but also the global effort to develop practical fusion energy.”

The Culham Campus, the home of the UK’s national fusion research programme, is owned and managed by UKAEA, widely recognized as a world leader in fusion energy development and innovation.

“This is a great development for UKAEA, very much in line with our mission to lead the development of sustainable fusion energy, and builds on our long heritage of hosting major fusion facilities such as the Joint European Torus,” said Ian Chapman, CEO of UKAEA.
