0841: Malcolm Grimston, a nuclear energy expert from Imperial College London, has told the BBC that as long as any nuclear meltdown is small -scale, it can be contained: "For example, there was one in the Chapel Cross plant in south-west Scotland in the 1960s, and at the end of that it only affected two of what they call the fuel channels, the long tubes where the fuel is put. They simply sealed those off, there was no release of radioactivity offsite and the plant continued to operate for 30 years." 0828: Japan's NHK TV showing before and after pictures of the Fukushima-Daiichi plant. It appears to show that the outer structure of one of four buildings at the plant is no longer there.
