Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Number 2 could well be a case where much of the steam is condensed back into water which leaks out of the containment vessel into the trenches.

Er - is it not obvious from visual inspection which containment vessels are leaking, and how?

Or have the high radiation readings around the cores made inspection impossible?

Well the one with the most inhabitable drywell round the reactor is testing at 18 Sieverts per hour, If there is any remote pictures from inside the reactor buildings, then they havent been publicly released

Any idiot can face a crisis - it's day to day living that wears you out.

#1 still had significant pressurization as of the injection of nitrogen last week end. #2 has been shown in diagrams to have had a breach of the torus and seems to be the source of a lot of the water in the trenches, but I haven't seen a lot of explicit information in the press. Have I missed significant photographic evidence from inside reactors? The release of steam into the atmosphere is obvious, but the source of those leaks is less so. To me pipe joints and gaskets where pipes penetrate the reactor pressure vessel remain obvious sources, but with the loss of pressurization in #2 and #3 it seems hard to say from the available information.
