Rubbish.
The stuff is stored in ponds while decay is going on.
If fission was going on the rods would never decay to the point where
they were safe to process.

While a few meters of water is enough to stop the decay radiation it
isn't going to stop the neutrons from killing the workers.

I suggest you look at the difference between decay and fission before
harry points it out.



TNP is quite correct - it's spontaneous fission:

https://en.wikipedia.org/wiki/Spontaneous_fission


Oh was that dennis? Wrong about everything as usual.

"Neutron radiation consists of a free neutron, usually emitted as a
result of spontaneous or induced nuclear fission. Able to travel
hundreds or even thousands of meters in air, they are however able to be
effectively stopped if blocked by a hydrogen-rich material, such as
concrete or water."

The specific shield for neutrons is of course water, and a few meters is
precisely enough to stop them.

Rods are stored in ponds precisely because it stops the neutrons.
Deuterium is formed.

And of course, neutrons are in fact part of the 'decay radiation'.

Which is of course is from the spontaneous fission of radioactive elements.

So one can safely say that dennis' post contained not one grain of
factual information, and was muddled and ignorant throughout.

Sight. That's what a lack of grammar school education gets you.
