BBC: Second troubled reactor uses PLUTONIUM plus uranium -- Potential for more severe situation than #1

Problems for second Japan reactor, BBC, March 12, 2010 at 10:16 pm EST:

The plant's operator says pressure is rising inside reactor No. 3 after it lost its emergency cooling system.

A similar problem led to a blast at the plant's No. 1 reactor on Saturday. ...

But the BBC's Chris Hogg in Tokyo says the second reactor is a different type which uses MOX (plutonium plus uranium) fuel and the consequences of a problem there are potentially more severe.
