Fukushima Daichi And Daini Having Still Risks of Continuous Radiation Releases

Last weeks 7.4 on Richter scale earthquake (updated from 7.3 to 7.4 afterwards) and a 1 meter tsunami made it clear to everyone that the danger of new wide spreading radioactive releases still exists at Fukushima Daichi and surprisingly also at Fukushima Daini nuclear power plant that is situated a few miles south of F. Daichi.

The earthquake made some kind of nuclear reaction to occur in Fukushima Daichi reactor 1 causing hydrogen levels in torus room and containment vessel to spike up. Nuclear engineers are concerned of situation though hydrogen levels haven't reached explosive mixture yet.

But the dark secret of TEPCO remain unsolved: what is the damage for the reactor core for Fukushima Daini reactors or even to Fukushima Daichi reactors 5 and 6 that have not been widely discussed publicly. The pressure of the containment vessel of Daini reactor 1 was increased after the recent earthquake and at least senior nuclear engineer Arnie Gundersen supposes some core damage have occurred in Daini reactor number 1 and perhaps in Daichi reactors 5 and 6 also. He came to this conclusion after having read the data of loss of cooling times after the tsunami had destroyed the possibility to cool down the reactors effectively. Loosing the diesel generators may have caused some core damage to F. Daini reactor 1 and this was perhaps causing the pressure increase also after the last week EQ.

Geologists have warned of a possible new earthquake of 8 on Richter scale to occur at the same region as last weeks EQ. That kind of quake could trigger a new nuclear disaster if the spent fuel pools couldn't stand the force of it. The fuel could run dry and overheat causing a significant fallout and make controlling of the  reactors very difficult or even impossible. That could mean a world wide fallout much more severe than Chernobyl was.

We can only hope and pray the worst scenarios not to happen. Meanwhile, we could learn something of the mistakes of the past.
