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.
