Poland and US sign deal to build large and small-scale nuclear energy

Posted by in category: nuclear energy

On Monday in Washington, D.C., an agreement was signed between American company NuScale Power and the Polish KGHM mining company to build nuclear reactors in Poland.

“We decided that Poland’s strategic partner in nuclear energy will be the United States and American companies. Both in building a conventional, large nuclear power plant, as well as introducing Small Modular Reactors (SMR),” Deputy Prime Minister and Minister of State Assets Jacek Sasin said during his visit to Washington.

He added that there were hopes that the first reactors will be able to start operating within the next seven to eight years.

Why the Nuclear Option is a Necessity if Humans Are Ever Going to Get to Mars and Return Alive

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

The ISS is 1,000 times closer to us than the Moon, and 600,000 times closer than Mars. To get to the latter and back safely, we need faster rocket propulsion systems.

Using the conventional chemical rocket technology we have perfected at this time, a single mission to Mars will require the launch of a mass equal to 10 ISS to be put into space. It will involve at least 30 and as many as 40 of the largest rockets we have today to put the spacecraft, crew and fuel needed for the mission. That doesn’t include adding reserves of fuel placed strategically along the route should a problem arise going to Mars and coming back. Brown states that the total cost of a single mission using this approach would exceed $80 billion using the yet-to-be-launched SLS as the primary vehicle. With SpaceX and the Starship and Heavy booster, the cost could be cut by half. But even $40 billion for a single mission seems excessive.

Using nuclear-powered propulsion systems, however, would eliminate the need to put megatons of fuel into orbit. The only time chemical rockets would be used would be in launching the crew and spaceship components to Earth orbit. That could be done in as few as three launches with the final assembled ship going to Mars and back and then being parked in Earth orbit to be used again on future missions.

The Morning After: European fusion reactor shatters energy production record

Posted by in categories: nuclear energy, particle physics

The Joint European Torus (JET) fusion reactor in the UK has generated the highest level of sustained energy ever from atom fusion. On December 21st, 2021, the “tokamak” reactor produced 59 megajoules of energy during a five-second fusion pulse. That’s double what it created back in 1997. (Yes, I know energy is not created or destroyed, but you get what I mean!)

The JET reactor is the flagship experimental device of the European Fusion Program, funded by the EU. It’s mainly designed to prove scientists’ modeling efforts, with an eye on future, bigger experiments with a much larger ITER reactor in France, set to start fusion testing in 2025.

JET hit a Q value of 0.33, meaning it produced about a third of the energy put in. The highest Q value achieved so far is 0.7 by the US Department of Energy’s National Ignition Facility, but it only hit that figure for 4 billionths of a second. The goal with ITER is to reach a Q factor of 10 or greater. Fun fact: ITER isn’t an acronym but means “the path” in Latin. And now you know.

It’s time to rethink Nuclear Power! Limitless Green Thorium Energy is coming

Posted by in categories: nuclear energy, particle physics

Nuclear power may not be as bad as you think. If we used Thorium instead of Uranium, we could greatly decrease dangerous radioactive by-products. There is enough Thorium in the world to meet all our energy needs for over 1,000 years.

In this video I show you how nuclear power plants work, and how Thorium can change the game. I aim to shift your views on nuclear power.

Explained: Breakthrough in nuclear fusion, and why it is significant

Posted by in categories: materials, nuclear energy

But the benefits of fusion reaction are immense. Apart from generating much more energy, fusion produces no carbon emissions, the raw materials are in sufficient supply, produces much less radioactive waste compared to fission, and is considered much safer.

Over the years, scientists have been able to draw up the plan for a fusion nuclear reactor. It is called ITER (International Thermonuclear Experimental Reactor) and is being built in southern France with the collaboration of 35 countries, including India which is one of the seven partners, alongside the European Union, the United States, Russia, Japan, South Korea and China.

Major breakthrough on nuclear fusion energy — BBC News

Posted by in categories: innovation, nuclear energy

European scientists say they have made a major breakthrough in their quest to develop practical nuclear fusion — the energy process that powers the stars.

The UK-based JET laboratory has smashed its own world record for the amount of energy it can extract by squeezing together two forms of hydrogen.

Major breakthrough in fusion energy

Posted by in categories: innovation, nuclear energy

The biggest breakthrough in fusion energy since 1997 has been reported today at the Joint European Torus in Oxford, UK, with 59 megajoules produced over five seconds (11 megawatts of power), more than double the previous record.
