Just a little clarification needed: I thought the best way to protect
any structure from earthquake damage was to "float" it. That is the
ground may move significantly side-to-side and up-and-down but as long
as the components of the building remained in the same relative
position there would be no catastrophic damage. The same principle
protects against other disasters such as hurricanes. Of course I'm
basing this on building code requirements for residential housing and
things may be more complex for very heavy and large structures such as
nuclear plants. Although enormous office buildings don't seem to come
For tsunami's I presume the protection was some sort of physical
barrier between it and the sea although none of the reports I've seen
seem to talk about this. Why do reactors have to be built right next
to the ocean or river? Presumably they don't actually pump out
potentially contaminated water into the ocean/river but instead use it
as a giant heat sink. It would doubtless cost more if the reactor were
built on a bluff or even an artificial mountain/hill to elevate it 100
meters or so above sea level but in many parts of the country there
are plenty of areas where this could be done. Doubtless the pumping
would be more expensive but I'm unconvinced it would be prohibitive.
Same goes with the people. Based on the videos all the areas where the
tsunami wreaked havoc were on a large near-sea-level plain where
people would have had to run or drive miles to any sort of safety.
Just a requirement to dot hills around the place would seem to be life
saving for many.
Just a thought...
He's not "totally" wrong and you're glossing over the differences in
fundamental design and safety margins of PHWR (Candu) vs BWR. In the
event of Station Black Out (SBO) + loss of ECCS w/o operator
intervention, a Candu reactor, due to the heat sinks provided in the
design from the low pressure/low temp moderator and water filled
reactor core, will very likely not "melt down" while a BWR certainly
will and did.
When the control rods are dropped, as they were in Japan within
seconds of the earthquake being detected, the reaction stops. All
that's left is the secondary radioactive byproducts producing heat as
they enter their half-life phase, which is a few days to a couple
No, nitwit. All nuclear power reactors need a functioning cooling
for days after the fission reaction is stopped. That's because the
continues to come from radioactive byproducts of the fission. You can
stop the fission, but you cannot stop the natural decay of those
radioactive byproducts. Ever hear of a spent fuel pool? Why do you
think they generate heat and must be cooled as well?
I'd like to see a credible reference that says the fission process
be stopped by inserting all the control rods in the GE reactor. Link
And what kind of nitwit starts speculating without having any of the
facts? We need a full investigation. So far, we hardly have any
at all as to what happened.
What a piece of shit you are, true crap, Put 30 feet of water over any
plant not designed to operate flooded and what do you have you ass
hole. There are always smart asses like you around. You are the true
Hmm. So far, no one has died (or even gotten sick) from the Japanese nuclear
A pundit who studied Chernobyl for 30 years recently concluded that more
people died from WORRY over the events at Chernobyl than from radiation
poisoning or its aftermaths.
This worry manifested itself in agitation over relocation, heart disease,
Type II diabetes, consternation, upheavals, etc. There was a ten-fold
increase in abortions as women feared their children might be born with god
It might be said, to coin a phrase, we have nothing to fear but fear.
No joke. There are three possible bad effects from radiation:
* Radiation sickness - you either get over it or you die. There is no
* Genetic mutation - there is no case on record of a mutated fetus surviving
* Cancer - Cancer is the most studied disease on the planet.
Next, there are no "mega quantities" of radiation in Japan (or at least none
The point the pundit was making is that there is a fourth deleterious health
effect: Fear. Fear, and the accompanying trepidation, causes heart problems,
psychological dysfunction, and irrational actions, such as tens of thousands
of elective abortions.
What does this have to do with home repair? Unless the discussion
touches on how much lead is needed to wrap a house near a reactor, then
this is the wrong newsgroup.
