Number 2 Reactor Explodes, Damaging Core Containment Structure

Washington’s Blog

There has now been an explosion at Fukushima reactor number 2 (reactors number 1 and 3 experienced explosions previously).

NHK reports:

The
sound of a blast was heard Tuesday morning at the troubled No. 2
reactor of the quake-hit Fukushima No. 1 nuclear power plant, the
government said.

 

The incident occurred at 6:10 a.m. and is
feared to have damaged the reactor's pressure-suppression system, the
Nuclear and Industrial Safety Agency said, citing a report from the
plant's operator Tokyo Electric Power Co.

MSN notes:

 

Chief
Cabinet Secretary Yukio Edano told reporters that "damage appears on
the suppression pool" -- the bottom part of the container, which
contains water used to cool down the reactor and control air pressure
inside.

 

"But we have not recorded any sudden jump in radiation indicators," Edano said without elaborating.

 

If
confirmed, it will be the first direct damage to the reactor since a
massive earthquake and tsunami battered Japan's northeast coast on
Friday, knocking out nuclear plants in Fukushima, north of Tokyo.

Kyodo News is reporting higher radiation levels North of Tokyo after the blast.

Arrrgggggh!

We're so sorry this disaster is ruining your day, please, just ignore it, take a chill pill, and go back to your shitty little blog.  We'll handle it from here.

What's that? 

Oh yes, we can handle it just fine.  Run along now, we wouldn't want your blood pressure getting up.

Did they have the geiger counters on?

They were turned on alright. But the equipment "recording" the figures happened to be turned off. Thus there were no "recorded" jumps. Also, there were no jumps in the readings, just a steady rise in the readings. 

You just need to understand how the duplicitous mind works, then control for official Newspeak.

"But we have not recorded any sudden jump in radiation indicators,"

This reminds me of the old pilot joke about an engine-out forced off-field landing at night ... as you get close to the ground, you switch on your landing light, and if you don't like what you see you turn it off.

  1. 0241: And Mr Kan also confirms earlier reports that a fire has broken out at Fukushima's reactor 4.

http://www.bbc.co.uk/news/world-middle-east-12307698

 

Addressing the nation, Prime Minister Naoto Kan says that "there is a high risk of futher radioactive material coming out".

The premier also urges people within 19 miles (30km) of the Fukushima complex in the area "to remain indoors".

No word yet on Gojiro.

So Units 1, 2, and 3 have all suffered explosions. Unit 4 was one of the units that was offline at the time of the quake. The situation is clearly proceeding according to plan.

The other three at the site weren't in operation, so they shouldn't be a problem.

Wrong. Where do you think they stored the rods removed from the 'not in use' reactors?

In the storage pools at the top of the reactor buildings. So in buildings 1 & 3, that had their tops blown off the pools are probably exposed. In building 4, there's obfuscation about where exactly the 'fire' was/is, but may well have involved the fuel rods. #4 was shut down for inspection, so the still-good rods would be stored in the pool along with all the old spent rods. For extra thermal neutron goodness.

It's very odd that in the satellite pic of the site after the first two explosions, the storage pools are not visible in the wreckage. They should be. Doctored images? Or the building structure is not per the GE Mark I BWR diagrams available on the net?

ATG, nothing wrong with his math...  Fukushima Diani, sister plant to the one that just blew up (Fukushima Daiichi).  Daini has 4 sister reactors with the same issues that Daiichi had just after the tsunami, they appear to have them in hand,,,,,, 

Unit 1 (shut down at 2:48PM on March 11th)
- Reactor is shut down and reactor water level is stable.
- Offsite power is available.
- Control rods are fully inserted (reactor is in subcritical status)
- Status of main steam isolation valve: closed
- Injection of water into the reactor had been done by the Reactor Core
Isolation Cooling System, but at 3:48AM, injection by Make-up Water
Condensate System begun
- At 6:08PM, we announced the increase in reactor containment vessel pressure,
assumed to be due to leakage of reactor coolant. However, we do not believe
there is leakage of reactor coolant in the containment vessel at this moment.

Unit 2 (shut down at 2:48PM on March 11th)
- Reactor is shut down and reactor water level is stable.
- Offsite power is available.
- Control rods are fully inserted (reactor is in subcritical status)
- Status of main steam isolation valve: closed
- Injection of water into the reactor had been done by the Reactor Core
Isolation Cooling System, but at 4:50AM, injection by Make-up Water
Condensate System begun.
- We do not believe there is leakage of reactor coolant in the containment
vessel.

Unit 3 (shut down at 2:48PM on March 11th)
- Reactor is shut down and reactor water level is stable.
- Offsite power is available.
- Control rods are fully inserted (reactor is in subcritical status)
- Status of main steam isolation valve: closed
- Reactor Core Isolation Cooling System is turned off. Currently, injection
of water into the reactor is done by Make-up Water Condensate System.
- We do not believe there is leakage of reactor coolant in the containment
vessel.

Unit 4 (shut down at 2:48PM on March 11th)
- Reactor is shut down and reactor water level is stable.
- Offsite power is available.
- Control rods are fully inserted (reactor is in subcritical status)
- Status of main steam isolation valve: closed
- Reactor Core Isolation Cooling System is turned off. Currently, injection
of water into the reactor is done by Make-up Water Condensate System.
- We do not believe there is leakage of reactor coolant in the containment
vessel.

Indication from monitoring posts installed at the site boundary did not show
any difference from ordinary level.
No radiation impact to the external environment has been confirmed. We will
continue to monitor in detail the possibility of radioactive material being
discharged from exhaust stack or discharge canal.
There is no missing person within the power station.
We are presently checking on the site situation of each plant while keeping
the situation of aftershock and Tsunami in mind.
A seriously injured worker is still trapped in the crane operating console
of the exhaust stack and his breathing and pulse cannot be confirmed.
A worker was lightly injured spraining his left ankle and cutting both knees
when he fell while walking at the site. The worker is conscious.

Unless you live in the Northern Hemisphere that is! Let's just hope they get this right the first time.

 

Here lurks the potential global Black Swan. (Sorry for the caps) Do not dismiss what 40 years of stockpiled spent fuel rods could do if combusted...

Why you ask?

Because they store the used fuel rods in a cooling pool above and adjacent to... are you ready for this?

ALL 6 of the GE Mark 1 reactors.

If the cooling pumps to the spent fuel storage pools fail the water will evaporate and the spent fuel will heat and may combust. I don't think I even have to tell you how bad that development could be but it would certainly likely be global.

 

http://news.yahoo.com/s/csm/20110314/ts_csm/369577

A particular feature of the 40-year old General Electric Mark 1 Boiling Water Reactor model – such as the six reactors at the Fukushima site – is that each reactor has a separate spent-fuel pool. These sit near the top of each reactor and adjacent to it, so that cranes can remove spent fuel from the reactor and deposit it in a swimming-pool-like concrete structure near the top of the reactor vessel, inside each reactor building.

 

If the hydrogen explosions damaged those pools – or systems needed to keep them cool – they could become a big problem. Keeping spent-fuel pools cool is critical and could potentially be an even more severe problem than a reactor meltdown, some experts say. If water drains out, the spent fuel could produce a fire that would release vast amounts of radioactivity, nuclear experts and anti-nuclear activists warn.

 

GE brings good things to life!

Or not.

How, pray TF tell, are the stored-adjacently spent fuel rods supposed to "combust" under any physics-respecting scenario?    This is not a movie on the sci-fi channel.

uranium fuel rods produce heat, they are considered spent when too many or too much actinides accrue within them- All actinides are radioactive and release energy upon radioactive decay; uranium, thorium, and plutonium, the most abundant actinides on Earth, are used in nuclear reactors and nuclear weapons.

http://en.wikipedia.org/wiki/Actinide

 

Even spent fuel rods are still thermally active, thats why they are kept in water it moderates the neutrons and is a great heat sink that pulls away the heat and dissipates it. No water surrounding the spent fuel rods means hot fuel rods exposed to atmospheric oxygen and likely some hydrogen if the rods began to melt or otherwise damage their cladding. Pretty soon you've got a real mess.
