Japan reactors decades from repair

One of Japan's crippled nuclear reactors still has fatally high radiation levels and hardly any water to cool its fuel, according to an internal examination that reinforces doubts about the plant's stability. The data collected showed the damage from the disaster is so severe, the plant operator will have to develop special equipment and technology to tolerate the harsh environment and decommission the plant, a process expected to last decades. The No. 2 reactor is the only one plant workers have been able to closely examine so far. Tuesday's examination with an industrial endoscope detected radiation levels up to 10 times the fatal dose inside the chamber. The other two reactors that had meltdowns could be in even worse shape. Three Dai-ichi reactors had meltdowns, but the No. 2 reactor is the only one that has been examined because radiation levels inside the reactor building are relatively low and its container is designed with a convenient slot to send in the endoscope. The exact conditions of the other two reactors, where hydrogen explosions damaged their buildings, are still unknown. Simulations have indicated that more fuel inside No. 1 has breached the core than the other two, but radiation at No. 3 remains the highest. The high radiation levels inside the No. 2 reactor's chamber mean it's inaccessible to the workers. Fukushima's accident has instilled public distrust and concerns about nuclear safety, making it difficult for the government to start up reactors even after regular safety checks. All but one of Japan's 54 reactors are now offline, with the last one scheduled to stop in early May.
