Title: Unit 1; Post Quake Reaction & Torus Oddity Indicate Larger Problem
Date: December 8th, 2012
We have reported extensively about a phenomenon going on inside unit 1 since the accident. Whenever there is a strong quake, the radiation in the Drywell B sensor goes up considerably, pressure and other readings tend to also fluctuate in unison. After the initial meltdowns these reactions were quite intense. Now 1 year and 9 months into the disaster we still see this same activity.
The recent 7.3 quake at Fukushima caused this same reaction.
[...] the reactions post quake and the ongoing hydrogen issue in the torus indicate something corium related going on in the torus.
[...] it appears hydrogen may have been increasing inside the torus after the previous purge effort, indicating the possibility of some sort of ongoing reaction in the torus.
This ongoing hydrogen reaction in the torus along with continuing to see post quake activity in the same area of the reactor indicate a continued event in the torus that can be picked up by the Drywell B sensor.
