Increased rate of water leakage at Fukushima reactors

Increased rate of water leakage at Fukushima reactors

A drop in the water levels in the reactor containment vessels of units 1 and 3 at the Fukushima Daiichi plant in Japan has been detected, Tokyo Electric Power Company has announced. The utility said the decreased levels probably indicate that existing damage to the units' containment vessels has been exacerbated by the recent earthquake that struck the region, allowing more water to leak from them.

Engineers publish new research on meltdown materials

Engineers at the UK's University of Sheffield have developed materials that they say could be used to help decommission the Chernobyl and Fukushima nuclear power plants. In the new research published today, they report their development of small batches of low radioactivity materials that can be used to simulate lava-like fuel containing materials. LFCMs are a mixture of highly radioactive molten nuclear fuel and building materials that fuse together during a nuclear meltdown.
