Thanks! I actually got in, using a different browser.

That doesn't sound as rosey as the Japanese version of events.

It certainly isn't.

Can someone tell me why a spent fuel rod gets hot? How big is a spent fuel rod? How long do they stay hot for when they are being 'stored' and how long do they have to be stored for?

Even after a fuel rod is "spent" it still decays, and produces heat as a by product. Not sure exactly how long they have to remain cooled for, pretty sure it's months if not years.

The rods are still decaying as said above. They create heat which is normally removed by the fuel pool system and covered by 10+ feet of water which acts as a shield for radiation.

They produce heat for quite some time. How long depends on thier time and position in the reactor. I do not know how long they require heat removal before they can be placed into a dry storage condition.

They have to be stored in the fuel pool until they are ready for dry cask storage or could possibly be taken for re-processing. The dry cask storage is for quite some time.

How serious is this so far, Should we in California or in general US should be alarmed because of the radiation, will it travel here? "mommy".

We had planned our honeymoon to Hawaii in June, does this mean i should cancel?
I will continue to pray for the people of Japan.

"Dry spent fuel storage in casks is considered to be safe and environmentally sound. Over the last 20 years, there have been no radiation releases which have affected the public..."

Yikes, kind of scary that they had to throw in the "which have affected the public" qualifier.


Replacing my Canon 7D, Tokina 12-24mm, Canon 17-55mm, Sigma 30mm f/1.4, 85mm f/1.4, and 150-500mm with a Panasonic Lumix FZ1000. I still have the 17-55 and the 30 available for sale.

One other thing to add on is that the need for cooling is in stages. After being decommissioned the rods require active cooling for some period of time, and eventually can be moved to a passive cooling system when their heat output drops below some threshold.

It's extremely unlikely that this situation will have a significant health effect outside of the immediate area, even in many of the worst-case scenarios. I have read and listened to literally dozens of expert opinions from around the world that unify behind this statement.

We opened a thread like this on a car forum. It got shut down pretty quick when people started stating the obvious (not rasism) but the obvious.
