In a CNN interview today John King talks to Arnold Gundersen of fairewinds. Gundersen explains how the hydrogen explosion in reactor 2, caused a breeched in containment leading to radioactive water filling the trenches and leaking into the ocean.

Gundersen puts into perspective the level of radiation being released into the ocean. He said the 11,500 tonnes of ‘low level’ radioactive water being damped into the sea, was 500 time higher then the permitted level. “They had to clear these tanks so that more radioactive liquid could come behind it.”

As reported in an earlier post some evidence emerging from few sources has lead experts to speculate that the reactor core in Unit 1 is still undergoing periodic Nuclear Fission.

Today Tokyo Electric Power Co. announced they are to inject nitrogen into reactor unit 1 at the crippled Fukushima Daiichi nuclear power complex, aiming to reduce the risk of a hydrogen explosion.

Stopping the leak in reactor 2 but discharging radioactive water from reactor 5 & 6 into the sea

However Japanese authorities have confirmed to the IAEA that they began to discharge 11,500 tonnes of low level radioactive water into the sea on 4 April. The operation is being conducted to create storage capacity for highly radioactive water pooled in parts of the reactor facility, hindering efforts to restore electrical power from the grid to the facility.

What is really going on In Fukushima? Nuclear Fission & Radiation 101

Radiation Stacks

Have you ever wondered what are those towers next to each reactors building in the Fukushima plant? These are the ‘Radiation Stacks’ looking like transmission tower they are there to vent radiation fumes for better dispersion in the event of an accident. Those stacks are designed to send radioactive emissions higher up into the atmosphere.

The radiation stacks in Fukushima were not used this time, as they need electricity to push the emissions up the stacks. And electricity was gone once the tsunami hit. Another problem is that radiation stacks are designed to suck the air out of the containment buildings and as we could clearly see from pictures and footage there are not much of the building left to suck the air of.

I had a dream

On the 3rd of March 2011, I woke up recalling a vivid dream, I felt that this dream was significant, so while rubbing the web of sleep from my half opened eyes, I recounted the dream to my partner, partly so I don’t forget it and partly so that there is another soul knowing I had that dream.

I told him – “I was taking part in a rescue mission, which took place within a ‘radiation zone’, I was aware that I didn’t have any protective clothing, or mask, but at the same time I knew with unexplained confidence, that I am not going to be effected by the high radiation.”

On the 3.3.11 a week before the 11.3.11 Japanese Earth Quake, Tsunami, and the Nuclear disaster that followed, the likelihood of me taking part in a rescue mission in a radiation zone was as remote and unrealistic as spaceships landing on the white house loan.(Not because I believe they don’t exist, but because I don’t believe they will be stupid enough to land in that location.) But still it felt significant enough for me to make a mental note of it.
