Good I guess, as long as you don't have an earthquake.

I haven't been opposed to nuclear power. I live about 20 miles from
one.
But this latest incident in Japan sure gives one pause.

I think the significant thing is that the problem wasn't the 9.0
earthquake, it was the tsunami. That makes most of the US reactors
somewhat immune to the biggest problem.

Except the one 5 miles from my house.....

Where is the fault that is going to cause the level 9 earthquake?

Also the Japanese Nuke plant is 40 years old. We have learned a lot in
that time. Does not require electricity to keep the emergency cooling
water flowing these days.


Ya but the US has 23 of them exactly like the Japanese one. All still
in service. That does not include the related models, just the
identical ones.

But agree, the model is obolete as you can't easily stop the chain
reaction with these dinosaurs.

I saw a graphic about this particular design. There are not actually
rods that can be pulled out and separated. the core is the material and
it can be slowed down by putting separator plates in, but it's all still
in one area...

There are moderator rods on well designed reactors where a material tha
surpresses nuetrons can be placed between the fuel rods. This
dramatically reduces the energy output of the core. Yes, you actually
push the rods in to stop the core reaction.

Commonly called Control Rods.... http://en.wikipedia.org/wiki/Control_rod

This reactor design, like the 23 ohers in the US do not have this
feature and others. The real crime hear is polticians to allow old
antiquate designed to operate probably past their originally indended
liftimes. Oh ya, someone will say they were designed for 100 year or
something, but what does man make that lasts a 100 years without heavy
maintance and upgrading along the way?

Further, they are now using newer high output MOX fuel in these things,
using plutonium as part of the mix. Real fun stuff when it melts.

I am no nuke expert, but know enough about science to know when
poliicians and reporters are selling the wrong line. I didn't have any
idea we were still running reactors designed in the 60's until this
incident. As any 1/2 baked responsible idiot would not trust that.
Clearly these nukes are being run until they drop.
