6/4/2011 | ITALIAN ONCOLOGISTS BACK 'YES' AT THE NUCLEAR REFERENDUM

AGI) Chicago - Italian oncologists unite to back the anti-nuclear referendum. From the ASCO congress in Chicago, the world's most important oncology summit, AIOM (Italian association of medical oncology) urges the people to vote 'yes' at the referendum to be held on 12 and 13 June. "Nuclear radiation is the most carcinogenic thing that exists - said AIOM president Carmelo Iacono - and it cannot be kept under control, as the Fukushima tragedy proved. Let's drop the nuclear plants project and let's start staking on alternative energy, which pollutes much less and which, unlike nuclear energy, does not pose a threat for health". . .

6/3/2011 | Exclusive Arnie Gundersen Interview: The Dangers of Fukushima Are Worse and Longer-lived Than We Think

"I have said it's worse than Chernobyl and I’ll stand by that. There was an enormous amount of radiation given out in the first two to three weeks of the event. And add the wind blowing in-land. It could very well have brought the nation of Japan to its knees. I mean, there is so much contamination that luckily wound up in the Pacific Ocean as compared to across the nation of Japan - it could have cut Japan in half. But now the winds have turned, so they are heading to the south toward Tokyo and now my concern and my advice to friends that if there is a severe aftershock and the Unit 4 building collapses, leave. We are well beyond where any science has ever gone at that point and nuclear fuel lying on the ground and getting hot is not a condition that anyone has ever analyzed."

6/5/2011 | Pressure in No.1 reactor drops close to atmosphere
Source: NHK World
Date: Sunday, June 05, 2011 10:50 +0900 (JST)
Tokyo Electric Power Company has found that pressure inside the Number 1 reactor at its Fukushima Daiichi power plant has dropped to close to the outside atmospheric pressure. It reaffirms that the reactor has been damaged.
The reactor is believed to have suffered a meltdown after the March 11th disaster. The meltdown apparently created holes in the pressure vessel and damaged the containment vessel, letting highly radioactive water flow below ground in the reactor building.
Pressure inside an operating reactor is normally around 70 atmospheres. But after the disaster, the pressure indicator showed 6 atmospheres in the Number 1 reactor, raising questions about data reliability.
On Friday, the utility replaced the gauge with a new one and made measurements again.
The reading was 1.26 atmospheres as of 11 AM on Saturday, almost equal to normal air pressure. The company says this proves that air inside the reactor is escaping outside.
But the utility estimates that the lack of a big hole in the reactor is keeping steam inside, leading to the slightly higher interior pressure.
TEPCO is also planning to install new pressure gauges at the Number 2 and 3 reactors to assess the situation accurately.
Note on above article: It is good to get new measuring equipment in to the reactor, but the MEXT (Ministry of Education, Culture, Sports, Science and Technology) data from the chart below shows that the pressure in reactor 1 is already known to be low at least since May 13, 2011 (which is the earliest value in this data set). It is not exactly news that the reactor pressure has been near 1.2 atmospheres. 1 MPa (megapascal) is approximately 10 atmospheres so multiplying the readings below by 10 gives a fairly close result based on atmospheres.

6/4/2011 | Gov't failed to release some radiation projections
Source: NHK World
Date: Saturday, June 04, 2011 09:05 +0900 (JST)
The Japanese science ministry has admitted failing to release some of its projections of how radioactive substances would spread if they leaked from the Fukushima Daini nuclear power plant.
The science ministry used a computer system called SPEEDI to calculate how radiation would spread depending on the weather and terrain.
It said on Friday that it had failed to release 37 projections for the Fukushima Daini plant. It made the projections once an hour from 6PM on March 11 to 9AM on March 13.
The ministry said it had overlooked the existence of the data because it stopped making projections for the Fukushima Daini plant on March 13.
It was found on Thursday that the Nuclear and Industrial Safety Agency had failed to release 5 SPEEDI calculations for the Fukushima Daiichi and Fukushima Daini nuclear plants.
The government said in May that it would release all projections made with the SPEEDI system.
