The U.S.’s last big nuclear-power project came in more than $16 billion over budget and seven years behind schedule. Now, the U.S. government wants to give the AP1000 another shot. President Trump is ...

China’s experimental thorium molten salt reactor has reportedly achieved sustained thorium-to-uranium fuel conversion, marking a major scientific first. The breakthrough could ease China’s dependence ...

Small modular reactors (SMRs) promise to de-risk the cost overruns and delays through factory production methods. Google has partnered with Kairos Power, Amazon has invested in X-energy and Microsoft ...

Two companies, TerraPower and Deep Fission, have proposed building advanced nuclear reactors in Kansas. TerraPower, co-founded by Bill Gates, is exploring a utility-scale plant with energy storage ...

In the heart of Provence, Southern France, the world's largest fusion energy experiment, which could be a step towards unlimited energy, has quietly entered perhaps the most critical stage yet. The ...

With concrete already being poured, this startup’s molten salt–cooled reactors could be the first to deliver cheaper, safer nuclear power. Like many new nuclear startups, Kairos promises a path to ...

Much of the world had been turning away from traditional nuclear power in recent decades. Aging plants, high construction costs, security risks and radioactive-waste challenges caused policymakers and ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control ...

The UK government has announced plans to build more than a dozen small nuclear reactors across the country, ushering in what it calls a new “golden age” for nuclear power. One of the ultimate goals is ...

Sometimes an idea is so elegant that it really deserves to work. One such is a proposal put forward by the boss of Deep Fission, an aspiring nuclear-power firm in Berkeley, California. Elizabeth ...
