A remotely-controlled robot sent to inspect and clean a damaged reactor at Japan’s Fukushima nuclear plant had to be pulled early when its onboard camera went dark, the result of excess radiation. The abbreviated mission suggests that radiation levels inside the reactor are even higher than was reported last week—and that robots are going to have a hell of a time cleaning this mess up.
Earlier this week, we heard alarming reports of a “significant” nuclear waste leak at Hanford, the largest radioactive waste dumpsite in the country. Should we be worried? Absolutely. But mainly because this is a symptom of a much bigger problem that’s been festering for decades.
Scientists have produced a powder of plutonium-238 for the first time in nearly 30 years in the United States, a milestone that they say sets the country on a path toward powering NASA’s deep-space exploration and other missions.
This video explainer by Kurz Gesagt focuses on why nuclear energy is actually terrible and something we should stop using because it’s so bad. The reasons are pretty obvious: nuclear energy leads to nuclear bombs, nuclear waste is really dangerous and nuclear accidents and disasters are catastrophic.
