Nuclear waste could power Europe for decades. This startup plans to prove it

Europe has been turning uranium into energy for over half a century. In the process, the continent has amassed vast stockpiles of nuclear waste. This radioactive material can take millions of years to become safe, and no one really knows what to do with it. Thorizon, a Franco-Dutch startup, has an idea: reuse the nuclear waste to generate new energy. The company is developing a small modular molten salt reactor (MSR) that runs on a mix of spent nuclear fuel and thorium, a radioactive metal with
