No no, we are best at cultivating algae and duckweed.

Nuclear Plants only have so many years of life, cooling ponds will need
conversion someday. I just bet there's an algae out there that eats
radiation. ;o) ~ jan

only if the radioactive material is a nutrient normally taken up by the algae,
unfortunately. Then there is a the problem of disposing of the radioactive algae.
what many people dont understand is that anything can become radioactive (well except
helium IIRC) that is in contact with penetrating radiation. Ingrid

Here again Ingrid,

This is where you are making a general assumption of
water used in a nuclear facility. The don't turn on
the local faucet to fill the pipes, plus it is a sealed
pressurized system. The water used in Nuclear reactors
has nothing in it but water. The water is super clean
in nuclear facilities just to prevent the possibility
of something like that happening.

I know this from personal experience because I used to
work in the Nuclear Field.

I think some people may be confusing waste pools with cooling ponds. As
Tom said, the cooling ponds never touch the redioactive isotopes inside
the reactor. The cooling system in the reactor is a closed loop system
that uses a heat exchanger to transfer the heat out of the water in the
reactor cooling system. The reactor coolant and the water from the
cooling pond never physically mingle.

OTOH, the waste pools are where discarded fuel rods are held. It's only
supposed to be temporary but until the politic*ians decide what should
be done, the fule rods still sit in many "temporary" pools. Those pools
are supposedly built so that nothing escapes from them.

modeling angle and whose father is a nuclear engineer)

I am not nuclear physicist, but I am fairly certain that you cannot become
radioactive simply by being radiated. You must be in contact with particles.
IE, if I was within a few feet of some plutonium it would kill me, but if I
were not directly exposed to "its" air, I could walk away and not be
radioactive.

And the cooling towers are a sight to see. I worked at a plant for a few
months, doing on nuclear stuff, but I parked near the towers every day. It
was weird to see how the updraft of the steam could actually pull the flow
of water slightly inward towards the center of the tower. Yup, the water
don't fall straight down in there. Very odd to see.

DH works at a nuclear plant and in cold weather they have nuclear winter around
the cooling tower. It 'snows' all around the towers.

depends on the radiation
alpha is stopped by paper
beta is stopped by aluminum foil
gamma is stopped by lead
http://puregold.aquaria.net/su1-2004...radiation.html

OTOH, neutron flux (like in reactors) destabilizes inorganic compounds when a
neutron ends up in the nucleus of other atoms.
http://puregold.aquaria.net/su1-2004...ear_power.html

Organic material doesnt readily become radioactive due to the type of material it is
made of, nearly 98% is water, altho all organic material is constantly incorporating
C14 (created at high levels in the atmosphere)
http://puregold.aquaria.net/su1-2004...ve_dating.html
And then there was the grad student who contaminated himself with Iodine 125 and so
much ended up in his thyroid he was told to stay away from his wife until the I125
decayed sufficiently.
radiation does not make people "glow in the dark".
OTOH, radioactive materials are routinely made in the lab by bombardment (typically
with a cesium source) .. used mostly for diagnostic purposes. And leading to a lot
of low level radioactive wastes. Ingrid
