The Japanese government has an unsolvable problem: what to do with more than a million tonnes of water contaminated with radioactive tritium, in store since the Fukushima disaster and growing at more than 150 tonnes a day. The water, contained in a thousand giant tanks, has been steadily accumulating since the nuclear accident in 2011. It has been used to cool the three reactors that suffered a meltdown as a result of the tsunami that hit the coast. Tritium is a radioactive element produced as a by-product by nuclear reactors under normal operation, and is present everywhere in the fabric of the reactor buildings, so water used for cooling them is bound to be contaminated by it. To avoid another potentially catastrophic meltdown in the remaining fuel the cooling has to continue indefinitely, so the problem continues to worsen. The government has been told that Japan will run out of storage tanks by 2022.
