Media release BWXT make significant progress towards producing life-saving isotope at Darlington

Posted by in categories: biotech/medical, nuclear energy

Peterborough, ON — Ontario Power Generation (OPG), its subsidiary Laurentis Energy Partners (Laurentis), BWXT ITG Canada Inc. and its affiliates (BWXT) are making significant progress toward the production of molybdenum-99 (Mo-99) at OPG’s Darlington Nuclear Generating Station. Mo-99 is a much-needed medical isotope used in over 40 million procedures a year to detect cancers and diagnose various medical conditions.

Over the past 24 months, a team of more than 100 personnel at BWXT and Laurentis designed specialized tooling at BWXT’s facility in Peterborough to enable the production of Mo-99 at Darlington. The manufacturing of this specialized tooling is currently underway at the same BWXT facility in Peterborough.

BWXT has also built a fabrication facility at its current location in Peterborough to produce Mo-99 components that will be delivered by the specialized tooling, which will be installed at Darlington. The tooling will deliver the molybdenum into the Darlington reactor for irradiation, which will enable Darlington to become the first commercial operating nuclear reactor to produce Mo-99.

Inside JET: The world’s biggest nuclear fusion experiment | On Location

Posted by in categories: nuclear energy, sustainability

Inside these walls, scientists have been trying for decades to create an unlimited source of energy, nuclear fusion. Welcome to JET, the world’s biggest nuclear fusion experiment.

Scientists argue that fusion could replace coal gas and nuclear fission in the energy mix alongside renewable energy, which can prove to be unreliable. If we can learn to control it, nuclear fusion could change life as we know it. But that’s a big if.

A cool advance in thermoelectric conversion

Posted by in categories: engineering, nuclear energy, quantum physics

More than two-thirds of the energy used worldwide is ultimately ejected as “waste heat.” Within that reservoir of discarded energy lies a great and largely untapped opportunity, claim scientists in MIT’s Department of Nuclear Science and Engineering (NSE). As reported in a recent issue of Nature Communications, the MIT team—led by Assistant Professor Mingda Li, who heads NSE’s Quantum Matter Group—has achieved a breakthrough in thermoelectric generation, which offers a direct means of converting thermal energy, including waste heat, into electricity.

A , or difference, within a material such as a metal or semiconductor can, through a phenomenon known as the Seebeck effect, give rise to an that drives a current. “For many materials, the is too low to be useful,” explains NSE Research Scientist Fei Han. “Our goal is to find materials with conversion efficiencies high enough to make thermoelectric generation more practical.”

The efficiency of thermoelectric energy conversion is proportional to a material’s , electrical , and something called the “” squared; it is inversely proportional to the . Because efficiency goes up with temperature, most thermoelectric materials used today operate in the range of hundreds of degrees centigrade. “But in our lives, most of the stuff around us is at room temperature,” Han says. “That’s why we’re trying to discover new materials that work effectively at or below room temperature.”

Tiny Nuclear Reactors Yield a Huge Amount of Clean Hydrogen

Posted by in category: nuclear energy

They’re another welcome weapon in the fight against fossil fuels.

After getting bodied in the news cycle for a few months, small modular nuclear startup NuScale Power has an additional potential path to the diverse energy market. In a new evaluation run by the U.S. Department of Energy’s Idaho National Laboratory, NuScale’s nuclear module performed effective catalysis for hydrogen.

America Finally Makes Plans for Its Own Nuclear Fusion Power Plant

Posted by in category: nuclear energy

It’s happening at last.

For the first time, a major group of American scientists has agreed to work toward opening a nuclear fusion plant by the 2040s. The timeframe is intentional, letting scientists work on and learn from giant projects like Europe’s ITER and China’s EAST before designing a prototype of a fusion plant for the United States.

Research group has made a defect-resistant superalloy that can be 3D-printed

Posted by in categories: chemistry, economics, engineering, nuclear energy, particle physics, space

In recent years, it has become possible to use laser beams and electron beams to “print” engineering objects with complex shapes that could not be achieved by conventional manufacturing. The additive manufacturing (AM) process, or 3D printing, for metallic materials involves melting and fusing fine-scale powder particles—each about 10 times finer than a grain of beach sand—in sub-millimeter-scale “pools” created by focusing a laser or electron beam on the material.

“The highly focused beams provide exquisite control, enabling ‘tuning’ of properties in critical locations of the printed object,” said Tresa Pollock, a professor of materials and associate dean of the College of Engineering at UC Santa Barbara. “Unfortunately, many advanced metallic alloys used in extreme heat-intensive and chemically corrosive environments encountered in energy, space and nuclear applications are not compatible with the AM process.”

The challenge of discovering new AM-compatible materials was irresistible for Pollock, a world-renowned scientist who conducts research on advanced metallic materials and coatings. “This was interesting,” she said, “because a suite of highly compatible alloys could transform the production of having high economic value—i.e. materials that are expensive because their constituents are relatively rare within the earth’s crust—by enabling the manufacture of geometrically complex designs with minimal material waste.

US Space Force and NASA Looking to Privatize Nuclear Spacecraft Production

Posted by in categories: chemistry, Elon Musk, nuclear energy, space travel

LOS ANGELES, CA / ACCESSWIRE / December 7, 2020 / US Nuclear (OTCQB: UCLE) is the prime contractor to build MIFTI’s fusion generators, which could be used in the relatively near future to power the propulsion systems for space travel and provide plentiful, low-cost, clean energy for the earth and other planetary bases once our astronauts get to their destination, be it the moon, Mars, Saturn or beyond. Chemical powered rockets opened the door to space travel, but are still far too slow and heavy even to travel to distant planets within our solar system, let alone travel to other stars. Accordingly, NASA is now looking to nuclear powered rockets that can propel a space vessel at speeds close to the speed of light and thermonuclear power plants on the moon and Mars, as these are the next steps towards space exploration and colonization.

The US Energy Secretary, Dan Brouillette, recently said, “If we want to engage in outer space, or deep space as we call it, we have to rely upon nuclear fuels to get us there… that will allow us to get to Mars and back on ‘one tank of gas’.” This is made possible by the large energy density ratio which makes the fuel weight for chemical fuels ten million times higher than the fuel that powers the fusion drive. NASA is now relying on private companies to build spaceships: big companies like Boeing, but more and more on high-tech startups such as Elon Musk’s Space-X, Jeff Bezos’s Blue Origin, and Richard Branson’s Virgin Atlantic.

While nuclear fission has been considered as a basis for the next generation of rocket engines, the fuel used for fission is enriched uranium, which is scarce, costly, unstable, and hazardous. On the other hand, thermonuclear fusion uses a clean, low-cost isotope of hydrogen from ordinary seawater, and one gallon of this seawater extraction yields about the same amount of energy as 300 gallons of gasoline.
