New Material Finally Makes It Into the Almighty Nuclear Code

Posted by in categories: materials, nuclear energy

Scientists working at Idaho National Laboratory (INL) have announced the approval of a new high-temperature metal after 12 years and a $15 million Department of Energy investment. Alloy 617, a “combination of nickel, chromium, cobalt and molybdenum,” is tolerant and strong at temperatures of more than 1,700 degrees Fahrenheit. The scientists say this means it could be used in existing high temperature nuclear facilities as well as cutting-edge applications like molten salt reactors.

For any new nuclear plant material, making the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code is like qualifying for the Olympics. Alloy 617 is the first new material to get into “The Code” in 30 years.

The Electric Vehicle Revolution Is Finally Hitting the U.S. Army

Posted by in categories: nuclear energy, sustainability, transportation

The JLTV is the successor to the Humvee, and the Army plans to buy at least 50,000 in the coming decades.
The Army, concerned that civilian adoption of electric vehicles could leave it vulnerable, is looking into making the JLTV itself an EV.
An electric JLTV would reduce the need for diesel fuel at remote outposts, with power provided by solar or nuclear energy.

GE Power Plays: Wind Might Blow Coal, Gas And Nuclear Away

Posted by in categories: business, nuclear energy

GE offshore wind: massive offshore turbine Haliade-X 12MW looks like a winner.

GE-Hitachi Nuclear Energy may be a receding opportunity.

GE might sell its steam power business and rationalise its fossil fuel interests.

30 Years Later, This Big Boy Fusion Reactor Is Almost Ready to Turn On

Posted by in category: nuclear energy

Could nuclear fusion finally be right around the corner… in 2035?

The International Thermonuclear Experimental Reactor, or ITER, is a 30-year-old project started by President Ronald Reagan and Soviet leader Mikhail Gorbachev. With tens of billions of dollars on the line, this experimental tokamak fusion reactor—a nuclear fusion plasma reactor where extremely hot, charged plasma spins and generates virtually limitless energy—is one of a handful of extremely costly “miniature suns” around the world.

Scientists explore the power of radio waves to help control fusion reactions

Posted by in categories: nuclear energy, physics

A key challenge to capturing and controlling fusion energy on Earth is maintaining the stability of plasma—the electrically charged gas that fuels fusion reactions—and keeping it millions of degrees hot to launch and maintain fusion reactions. This challenge requires controlling magnetic islands, bubble-like structures that form in the plasma in doughnut-shaped tokamak fusion facilities. These islands can grow, cool the plasma and trigger disruptions—the sudden release of energy stored in the plasma—that can halt fusion reactions and seriously damage the fusion facilities that house them.

Improved island control

Research by scientists at Princeton University and at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) points toward improved control of the troublesome magnetic islands in ITER, the international tokamak under construction in France, and other future facilities that cannot allow large disruptions. “This research could open the door to improved control schemes previously deemed unobtainable,” said Eduardo Rodriguez, a graduate student in the Princeton Program in Plasma Physics and first author of a paper in Physics of Plasmas that reports the findings.

Inertial-confinement fusion with lasers

Posted by in categories: military, nuclear energy

Circa 2016

The quest for controlled fusion energy has been ongoing for over a half century. The demonstration of ignition and energy gain from thermonuclear fuels in the laboratory has been a major goal of fusion research for decades. Thermonuclear ignition is widely considered a milestone in the development of fusion energy, as well as a major scientific achievement with important applications in national security and basic sciences. The US is arguably the world leader in the inertial confinement approach to fusion and has invested in large facilities to pursue it, with the objective of establishing the science related to the safety and reliability of the stockpile of nuclear weapons. Although significant progress has been made in recent years, major challenges still remain in the quest for thermonuclear ignition via laser fusion. Here, we review the current state of the art in inertial confinement fusion research and describe the underlying physical principles.

Did US Navy patent a functional fusion device?

Posted by in categories: nuclear energy, transportation

The US Patent Office has issued a patent for a Plasma Compression Fusion Device to Salvatore Pais, of Calloway MD. The patent assignee is the United States of American as represented by the Secretary of the Navy, Patuxent River MD.

The news of this patent issuance has produced a minor buzz that might turn into a cacophony or a flurry of excitement about ships, submarines and perhaps even aircraft powered by high powered, compact devices using a “virtually unlimited” fuel source.

I suspect many of the articles that might be written will gush about how these fusion devices will be far superior to conventional atomic fission devices because they will not produce radioactive waste products. [Right.].

Scientists think we’ll finally solve nuclear fusion thanks to cutting-edge AI

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

Scientists believe the world will see it’s first working thermonuclear fusion reactor by the year 2025. That’s a tall order in short form, especially when you consider that fusion has been “almost here” for nearly a century.

Fusion reactors – not to be confused with common fission reactors – are the holiest of Grails when it comes to physics achievements. According to most experts, a successful fusion reactor would function as a near-unlimited source of energy.

In other words, if there’s a working demonstration of an actual fusion reactor by 2025, we could see an end to the global energy crisis within a few decades.

‘You’re basically right next to the nuclear reactor.’

Posted by in categories: biotech/medical, mobile phones, neuroscience, nuclear energy

I’ve been shocked sometimes when I walk in and see the patients. Most of the ones I’ve intubated are young — 30s, 40s, 50s. These are people who walked into the ER because they were coughing a day or two ago, or sometimes hours ago. By the time I come into the room, they are in severe respiratory distress. Their oxygen level might be 70 or 80 percent instead of 100, which is alarming. They are taking 40 breaths a minute when they should be taking 12 or 14. They have no oxygen reserves. They are pale and exhausted. It puts them in a mental fog, and sometimes they don’t hear me when I introduce myself. Some are panicky and gasping. Others are mumbling or incoherent. Last week, one patient was crying and asking to use my phone so they could call family and say goodbye, but their oxygen levels were dropping, and we didn’t have time, and I couldn’t risk bringing my phone in and contaminating it with virus, and the whole thing was impossible. I kept apologizing. I just —. I don’t know. I have to find a way to hold it together in order to do this job. I tear up sometimes, and if I do, it can fog up my face shield.

Utilizing relativistic effects for laser fusion: A new approach for clean power

Posted by in category: nuclear energy

Researchers at Osaka University studied a new approach for laser nuclear fusion utilizing relativistic phenomena of intense laser light. By irradiating the ultra-intense laser light directly onto the fusion fuel, the researchers examined signs of heating of fusion fuel. This work may lead to widespread, clean fusion power.
