Re: pentax to close customer service center etc because of, rolling blackouts in Japan

[Joseph McAllister]

Since I wrote this, the talking heads have backtracked to a scenario where 
units 5 & 6 are on a generator, allowing water to be pumped into the spent fuel 
pools. 

They are in the process of running power lines to the complex, but are not 
there yet. Demystification has not arrived in TelleyLand.

Yes I've heard of other schemes where that is done (one in Tasmania perhaps?).  
To me it seems a very good way to make use of wind / solar power as it must be 
about the cheapest and most efficient method of large-scale energy storage.

It was just announced on MSNBC that electrical power was just restored to the 
complex. Hopefully this will allow some pumps to work, some controls, and the 
metering systems to be brought online. A much better overview should be 
available within 24 hours (Saturday, Japan Time).

I would think that quite a bit of the electrical circuitry in some of those 
units would have been damaged beyond use from the explosions. We shall see. 
Units 2, 5, & 6 will be in good shape. That leaves only 1, 3, & 4 to be dealt 
with ASAP.

Best of luck over there. Thinking of you all the time.

These are said to be on a floor above the reactor, with no strong
ceiling or lid. There's a small diagram at:

http://www.nytimes.com/interactive/2011/03/16/world/asia/reactors-status.html

Things might have turned out better if the spent fuel were in the
basement, and the diesel generators were on the upper levels.




The one I helped build back in the late 70's has a much more massive 
containment structure. At the scale of the diagram, the spent fuel pool 
structure would have been about as large as the reactor building shown 
there and the spent fuel pool itself would have been about 1/3 of the 
volume.


That looks like the GE boiling water reactor design is a bit smaller and 
not as well protected. We've got two of those here in North Carolina 
down at Southport on the Cape Fear River. The plant I worked on was for 
a Westinghouse pressurized Water reactor design.


The top of the spent fuel pool would have been up where the spent fuel 
pool is in the diagram, but the bottom of the pool would have been down 
at the level of the "torus".


It was that way so the water level in the reactor building could be 
raised up above the top of the open reactor vessel for fueling. The top 
of the open vessel would be under about 30 feet of water during fueling 
operations so that the 24 foot fuel bundle could be lifted in and out 
without ever breaking the surface. Once the spent fuel was transferred 
back into the spent fuel pool, the cap would be bolted back on the 
reactor vessel and the reactor building would be pumped dry again.


One of the emergency cooling options for the reactor was to just pump 
the containment building full of water and circulate that water through 
the interchange with the cooling towers.


The diesel generators used for starting the system at Shearon Harris 
here in Wake County were located in their own buildings outside of the 
reactor complex (on the far side of the generator building from the 
containment). Those diesel generators are massive, with the actual 
generator portion itself being as big as a railroad locomotive.

There's one in West Virginia that works sorta' that way.

The reservoir is on top of a mountain with the nuke plant down by a 
river below. The nuke plant runs at a steady load around the clock.


Any time demand for electricity drops below what the nuke plant is 
generating the excess electricity is used to pump water up to the 
reservoir on top of the mountain.


When demand gets high the water is allowed to run down again to power 
hydro generators.


I don't think there was any provision made to use the water from the 
reservoir for emergency cooling.

The containments are already breached.

But the place where the helicopters are dumping water is a storage pool 
for spent fuel rods, not inside the reactor. I think they've managed to 
get some cooling water into the reactors.

An earthquake strong enough to breach structure like that wouldn't leave

To get water out of the storage pool you had to suck it out uphill. 
There's supposed to be enough water in the pool to cover the spent fuel 
rod bundles and keep them cool even if they temporarily lose the ability 
to add water to the pool.


If the pool is breached in some way that it has drained, they can't dump 
enough water from helicopters to bring the reactions under control. 
They're going to have to get multiple water pipe into that building to 
get control of the situation.


Chernobyl was a dry pile design and the helicopters there were dumping 
sand and cement on to the exposed core. The sand and cement didn't flow 
away like water will. Over time it built up in layers to contain the 
reaction so that they could get a more permanent cap in place.

Excellent solution!  The hydroelectric generated power could power the rural

be sent to urban environs, to keep the neon nice and bright…
In a catastrophe, cut off the rural users, after all, they have their whirly

That is the challenge, once the fuel rods are uncovered. They get so hot that 
trying to cover them again with anything that could help reduce or stop the 
loss of coolant creates more steam which becomes volatile in contact with the 
hydrogen being released by the degrading fuel rods because it presents free 
oxygen to an increased amount of hydrogen.  Like H3 0.

So the helicopters that are currently (as I write this on Thursday morning 
Japan time) dumping water on the hot (burning at times) spent fuel rods would 
have to dump a lot in a short period of time to prevent it being boiled off 
instantly. They should be, and may be, dropping a slurry of water and sodium 
hydroxide (I think hydroxide, maybe not).

And yes, the valves are designed to deal with tremendous pressures, until they 
fail of course.

Russia did not see fit to buy insurance for their reactors, in hindsight a poor 
vision of the possible problems. 

But it' not just science and weaponry that need underwriting protection, it's 
the rider on every other insured within reach of a nuclear incident.

this is actually something that has been boggling my mind since I
started thinking about what these poor people at fukushima who are
still their and giving their lives for what amounts to palliative care
of the plant and hopefully turning a 100% disaster into an 80%
disaster are doing all day.

I would kind of think that all this pumping of water onto fuel rods
glowing at somewhere between 800 and 2500 °C would cause instant
evaporation and the corresponding shock waves of pressure rises; AFAIK
water expands 1700fold from liquid to vapor/gaseous after all.
wouldn't that cause enormous stress and ultimately fatigue of the
containment vessel? and are the pressure relief valves designed to
withstand this abuse for an extended period?

I agree with that as well. If I recall though, to get a good water flow into a 
reactor with pump failure, one needs to vent the pressure from the containment 
vessel, normally through the Torus in these units, though in an emergency 
greater than that there are valves that can be opened to vent the steam from 
the boiling water out the top of the vessel.

The downside of that is, if you remember from science class, if you have 
superheated water under pressure, removing the pressure lowers the boiling 
point of the liquid, which causes a great amount of steam to be generated that 
needs to be released. Sort of a cascading problem, because at some point so 
much water is being turned to steam that it lowers the water level, perhaps 
faster than water can be pumped in to replace it.

I do not claim to know everything about the operation of the GE reactors in 
trouble in Japan right now. I did learn the basics as a teenager some 50 years 
ago, conversing with my father as well as listening in on many conversations 
over dinners with several of the big names in the Atomic Energy business. R.G. 
McAllister was a Nuclear Health Physicist sent to represent the the U.S.A. 
Insurance Pool at several ISO conventions held at the Hague in the 1950's and 
60's where the many safety measures in the use of these radioactive materials, 
from dentists and hospital use up to weapons production, were discussed and 
agreed upon. The reason for these month long meetings was that no insurance 
company, nor any country's insurance industry, could afford to cover a 
catastrophic event such as the one we are currently witness to in Japan. The 
risk had to be covered on a global scale. 

Don't be surprised if some of the large insurance companies in the world start 
selling off assets such as downtown buildings and other properties in the next 
year or three.

unique: not really. I hold the firm believe that large corporations
have no ethics whatsoever. all they care about is profit. it is called
shareholder value. and their managers had better be some place safe on
the day of the grand awakening.
safer: yes. depends of course. dams can break. coal is dirty. oil is
dirty. gas is somewhat dirty. deepwater horizon told its own story.
shell in nigeria is yet another story. photovoltaics are IMO safe but
produce lots of toxic waste in panel manufacture. wind turbines...
well, they kill birds and the offshore wheels apparently disorient
whales and dolphins. solar thermal plants seem fairly safe. sodium
acetate waste heat storage looks pretty promising. they all have one
advantage though: nothing they do has anywhere nearly the half life of
plutonium or MOX.

"much higher" is your problem here, Joe - it would need to be probably
something like at least a a mile higher if my guess of the pressure is
anywhere near realistic... but I do agree that there is much still to

There ya go! 

Except don't those pumps need power to operate to get that water up the hill to 
the power plants? And isn't that the main glitch in the systems in Japan right 
now? Well, they have generators to provide that, don't they? And they did use 
some, I don't know if the original ones or some brought in to replace the 
capability of those rendered inoperable by the Tsunami. Don't know the 
specifics. But from what I understand those were a no-go because they couldn't 
get the fuel to power them after the first day or so.

As I discussed with some friends yesterday, I think any reactors built in the 
future should be situated uphill from the ocean, and downhill from a gazillion 
gallon water source, like a lake or man-made reservoir, that could gravity feed 
reactors for a few weeks in an emergency. It would need to be much higher than 
the plant, as it takes quite a but of pressure to pump water into a pressurized 
containment vessel.

Oh, I don't think anybody would argue too strongly with you there.

It's just that you seem to have some quaint belief that this is is
some way unique to nuclear power, and that coal/oil/gas/whatever
is in some way a safer option.

The main difference is that the nuclear industry concentrates their
risk into highly-visible incidents such as the one we see at present,
while other methods of power generation spread their level of risk
uniformly over the time period.  That doesn't mean that the total
level of risk over time is lower, though.

here's how the different perspectives are reported on the live feed on the
BBC website at the moment:

1525: The EU's energy chief Guenther Oettinger has said that in the coming
hours "there could be further catastrophic events, which could pose a threat
to the lives of people on the island". He told the European Parliament the
Fukushima nuclear site was "effectively out of control". "The cooling
systems did not work, and as a result we are somewhere between a disaster
and a major disaster."

1520: The IAEA says the Japanese authorities "have reported concerns about
the condition of the spent nuclear fuel pool at Fukushima Daiichi Unit 3 and
Unit 4".

Well, I gotta tell you this story then. Heard it on the local news 
program just a couple days ago.


There were a local mass media crew in Japan that were reporting live to 
the news program. So the guy (photog by the way) tells that he and his 
accomplice were walking down the Tokyo subway and chanced upon a woman 
whom they asked some question or other. She immediately produced two 
masks and instructed them how to watch their clothes (long sleeves, wide 
brim hat, sun glasses, etc) so as to minimize the contamination.


You may actually have a point. That's amazing degree of social intelligence.

Nonetheless, Cotty, admit that if a 12 million city runs out of food on 
the shops shelves, that's gonna be nasty.

yes, in the form of more or less hot water. which as you know promotes
algae growth and reduces oxygen levels in rivers which as you know
affects the aquatic fauna or in other words kills fish. which in turn
results in power plants being shut down to protect said fish. that is
what happened. during the great droughts of the last decades a number
of plants in france and spain had to shut down. incidentally at a time
of rising power consumption caused by increased load from air
conditioners. nuclear power plants very much do destroy water in that
they make it uninhabitable to fish if you just let them run full
throttle.

oh and speaking of water, in the past 1000 years of recorded history
and not counting 2011 in Japan 150.000+ tsunami victims are
documented. not counting the unsung. someone with a little more brains
and a little less greed would not have placed their nuke plants on the

the nuclear power industry has no genuine interest in safety where
costs can be avoided. and no genuine interest in transparency either
if you look at Tepco's record (or Vattenfall's or ... well you name

I know of at least three.  Not to mention suspected failures in portables.



Are you aware that fly ash from coal plants release 1000s of times

There is plenty of Uranium on this planet, it's not really rare.
Besides that, the waste fuel can be re-used (but currently isn't due

can be extended for several usage cycles.

I don't believe the quote at all. It's pure braggadocio...

nothing can happen over here. they've seen to everything!

This is a totally deceiving statement.
Nuclear power plants "use" water to cool, and then return the water to the 
source. They do not _use it up_! They do not destroy it!
Once the power plant is done with it's cooling properties, it's returned to

Re: pentax to close customer service center etc because of rolling blackouts in Japan

Oh, if you think that's bad look up the published specifications of the 
US DOE's latest Tokamak, a basket ball court sized device with 
superconductors holding nearly an atomic bomb's worth of energy 
surrounded by a liquid sodium blanket.  What could go wrong?

I bet he did !   If our nuclear specialists were to be believed ( and 
since Tchernobyl, we certainly haven't believed a word they  said ) , 
nothing can happen over here  . they've seen to everything !
... except maybe during  a  summer draught a few years ago   but 
then they had forgotten that nuclear plants need huge amounts of water 
and water is scarce during draughts .


anyway better not worry too much about it now there are 58 plants all

If the latest round of scare stories are to be believed, you're in
more danger from radiation at US airports from those TSA scanners
than you would be from camping outside the gates of the Japanese
nuclear plants.

That only makes sense if you can come up with a viable alternative.
Renewable energy isn't there yet, and everything else is at least
as dangerous as a (well maintained, sensibly situated) modern
nuclear plant.  Reducing the world's energy demands might be the
best solution, but you know that isn't going to happen overnight.

It's more a sad reflection on human nature.

Somebody will always try to cut corners, skimp on inspections, etc.
It doesn't matter if it's a nuclear power plant, a deep-sea oil well,
a copper mine, a gas pipeline, ...  There's no accountability, and
no personal risk - It's only somebody elses life on the line.  It's
always cheaper to buy off the legislators than to fix the problem.

If breeder reactors had no technical issues at all, you wouldn't have
to blame the government. The Fast Flux Test Facility in USA was an
experimental breeder of sorts, wasn't it? IIRC it used liquid sodium
for cooling the core, but transferred the energy to steam before
putting it through the turbines. Nobody knows if that design is
quake-proof. It's probably not. If the steam leaked into the sodium
cirquit, it would ka-boom enough to maybe even satisfy Marvin the
Martian. :-)

Not that I claim to be an expert on these things, but then again, who is?

Re: pentax to close customer service center etc because of rolling blackouts in Japan

[David Parsons]

The nuclear industry has a very good safety record and I would much
rather rely on nuclear than coal or gas for power.  Figure 2
catastrophic failures in 60 years (and contrary to public opinion, TMI
was very well contained) with nuclear power generation.

Are you aware that fly ash from coal plants release 1000s of times
more radiation on an annual basis than has ever been released from a
nuclear plant?

There is plenty of Uranium on this planet, it's not really rare.
Besides that, the waste fuel can be re-used (but currently isn't due
to government policies, not from any technical reason) and the supply
can be extended for several usage cycles.

Re: pentax to close customer service center etc because of rolling blackouts in Japan

[eckinator]

Bob, there is a rule in IT operations that says "whenever someone
becomes indispensable [you must] fire them right away [before their
damage potential gets even greater]". if there are no good
alternatives to dangerous nuclear power plants, i.e. no safe nuclear
power plants, then the world will have to do without nuclear power
plants altogether or at least make an effort to do so. We can't just
keep building new ones and pretend we're aware of the risks (well
they're NOT risks but FACTS) and feverishly looking for a way out of
that technological dead end. Not to mention that Uranium is running
low so the price of nuclear energy is going to go up, not down. There
are alternatives and I'll prefer any of them no matter what other ill
effects they may harbour. and besides, the best alternative is to cut
down consumption. In Germany there are presently two nuclear plants
running exclusively to feed the goddamn STANDBY circuitry of home and
office electronics. I don't want to see the world go down the drain
because some fatass needs a FUCKING STANDBY LED on their bloody 42"
couch potato illumination!!!

Re: pentax to close customer service center etc because of rolling blackouts in Japan

[eckinator]

INES level is up to 6 from 4 now according to French ASN. Chernobyl
was 7. The situation is different in that Fukushima 1 (Daiichi) is not
graphite moderated so there can be no graphite fire but a steam
explosion isn't so bad either. All 6 blocks in varying degrees trouble
now, at least 200 tons of "spent"fuel rods in cooling basins outside
the containments, a broken containment in block 2, radiation levels
too high in the control room etc... One expert named Mycle Schneider
was quoted saying all being done now was "palliative". Oh, and two
block cooling failures in Fukushima 2 (Daini) yet to evolve. Tokai and
Onagawa look safe so far. Speaking of safe, French Sarkozy just
announced there will be no stop to French nuclear plans as French
reactors are (quote) ten times safer than those in Japan. Same from a
number of other countries or to a similar vein. Fukushima Daiichi was
built using a 60s GE design and hasn't been upgraded much since. So
much for lessons learned from Chernobyl. Not even the Wallmann valves
were redundant apparently. And Tepco was involved in a number of cover
up scandals including forged maintenance docs.

It scares the living daylights out of me to think that noone seems to
learn a thing from this. No matter how safe you make a nuke plant, you
can never reach 100% and any failure of this order of magnitude will
have similar effects. And it will happen again. Probably still in my
lifetime.

The current situation at Fukushima is nowhere near a 'Chernobyl'
situation. Chernobyl was something entirely different, with the
resulting explosion pushing highly radioactive material well into the
atmosphere where it was carried by prevailing currents far across the 
world.


Fukushima (at time of writing) is still very localised, even if there 
is

radioactive material venting.

Cotty, I am certain that Japanese learned the lessons of Ukrainians. I 
am also certain that technical pedigree of gear and engineering staff is 
superior in Fukushima.


I am more worried by the panic that may ensue. Consider city such as 
Tokyo (I reckon it is good double digit figure of millions of 
inhabitants) in mass panic?! That's what really frightens me.
