Bei einer Kontrolle im Kernkraftwerk Leibstadt wurde am 24. Juni 2014 festgestellt, dass die Halterungen für zwei Feuerlöscher mittels Bohrungen am Primärcontainment befestigt waren. – Bohrlöcher im Primärcontainment des Kernkraftwerks Leibstadt

Or, as @rysiek put it:

That time when someone decided that it is a good idea to install a fire extinguisher by way of drilling holes for screws in (checks notes) primary containment building of an active nuclear reactor.

Uuugh! I grew up in sight of the Leibstadt plume. 😬

Tritium is very dangerous. It gets inside you easily. It exchanges with normal hydrogen, sometimes it becomes organically (covalently) bound. It causes genetic damage at tiny conventional doses... I spent three years in the late 1990s looking at cancer and child leukemia near the Irish Sea supported by the Irish State. Tritium is measured in surface water – Is the Release of Radioactive Contaminated Water From the Fukushima Nuclear Site to the Sea Acceptable? Is It Safe?

Is the Release of Radioactive Contaminated Water From the Fukushima Nuclear Site to the Sea Acceptable? Is It Safe?

By Chris Busby, for Counterpunch

Chinese statistics show that 13 nuclear power plants in China each released more radioactive tritium into the ocean in 2021 than the planned amount to be released from Japan’s Fukushima Daiichi nuclear power plant in one year. – 13 China plants released more tritium in 2021 than Fukushima annual total plan

Keeping accidents a secret kills trust. Publishing accidents kills trust. Perhaps we just shouldn't trust nuclear power plants.

The Rocky Flats Plant, a former U.S. nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries. The contamination primarily resulted from two major plutonium fires in 1957 and 1969 (plutonium is pyrophoric, and shavings can spontaneously combust) … The contamination of the Denver area by plutonium from the fires … was not publicly reported until the 1970s. – Radioactive contamination from the Rocky Flats Plant

The cleanup is not going well. It’s been 13 years and 0g out of 880t have been removed.

Thirteen years since a massive earthquake and tsunami struck the Fukushima Dai-ichi nuclear power plant in northern Japan, causing a loss of power, meltdowns and a major release of radioactive material, operator Tokyo Electric Power Co. (TEPCO) finally seems to be close to extracting the first bit of melted fuel from the complex—thanks to a special telescopic robotic device. … It will take decades to decommission Fukushima Dai-ichi, and one of the most dangerous, complex tasks is the removal and storage of about 880 tons of highly radioactive molten fuel in three reactor buildings that were operating when the tsunami hit. – How a Robot Is Grabbing Fuel From a Fukushima Reactor

Nuclear energy for artificial intelligence:

Google has become the latest tech giant to seek nuclear power as a source for its datacenters and other operations. … Google hopes to spark chain reaction with nuclear energy investment, by Simon Sharwood, for The Register
Three Mile Island, the site of worst nuclear disaster in the United States, is reopening and will exclusively sell the power to Microsoft … Microsoft will purchase the carbon-free energy produced from it to power its data centers to support artificial intelligence. … However, nuclear has drawn criticism for environmental groups for decades for its waste. The US still has no permanent repository for that waste, instead storing it at over 70 operating and shuttered plants around the nation. – Three Mile Island is reopening and selling its power to Microsoft, by Jordan Valinsky, for CNN

Too unsafe to restart:

Japan’s nuclear watchdog on Wednesday formally disqualified a reactor in the country’s north-central region from restarting, the first rejection under safety standards that were reinforced after the 2011 Fukushima disaster. The decision is a setback for Japan as it seeks to accelerate reactor restarts to maximize nuclear power. – Japan’s nuclear watchdog disqualifies a reactor for the first time since Fukushima disaster, by Mari Yamaguchi, for AP

Problems:

The newest and most powerful nuclear reactor in Europe that was delivered more than a decade late and nearly four times over budget is also proving to be a headache for grid operators now that it is finally up and running. … Olkiluoto owner TVO says the reactor tripped on Sunday due to a turbine malfunction in the generator’s seal oil system. “The repair is taking longer than expected, and based on the current information, the plant is estimated to return to electricity production in approximately two days,” it said in a statement. … In October, it was forced to reduce power suddenly when one of the reactor’s control rods unexpectedly dropped into the reactor. Its sister reactor, Olkiluoto 2, was off line for three weeks due to a faulty water-cooled rotor that had to be replaced and will run for months at reduced output because of the fear of failure. – Big batteries and EVs to the rescue again as faults with new nuclear plant cause chaos on Nordic grids
