Throw this into the 2012 bag
« on: November 27, 2011, 01:54:20 PM »
Still trying to confirm via other sources.

A report by the Search for Extraterrestrial Intelligence (SETI) in the United States said that there are three giant spaceships which are heading towards Earth.

According to the Russian Pravda news, the SETI, a non-commercial organization said that the largest one of the three spaceships is 240 kilometers wide, and the two others are smaller.

Eh maybe not so much

You know, as much as it would cause some major strife I think a decent earth directed x flare could establish some sanity on this planet. We can worry about the nuclear power plants failing at a later date.

Once the generators run out of fuel... Meltdown.

What would happen if there was no power going to the plants? Nothing or total meltdown?

If the back-up generators keep working long enough to complete a cold shut-down, then nothing.

See "San Diego Power Outage Shuts Down San Onofre Nuclear Power"
at http://www.huffingtonpost.com/2011/09/08/san-diego-power-outage-sh_n_954892.html

The disaster at Fukushima, Japan, was due to the tsunami wrecking the back-up generators.

From http://www.world-nuclear.org/info/inf06.html:
" Scrams, Seismic shutdowns
A scram is a sudden reactor shutdown. When a reactor is scrammed, automatically due to seismic activity, or due to some malfunction, or manually for whatever reason, the fission reaction generating the main heat stops. However, considerable heat continues to be generated by the radioactive decay of the fission products in the fuel. Initially, for a few minutes, this is great - about 7% of the pre-scram level. But it drops to about 1% of the normal heat output after two hours, to 0.5% after one day, and 0.2% after a week. Even then it must still be cooled, but simply being immersed in a lot of water does most of the job after some time. When the water temperature is below 100°C at atmospheric pressure the reactor is said to be in "cold shutdown" "

Oii!  We were all thinking backwards (slaps forehead).

The nuclear power plants are the generators of electricity; they do not require an exterior source of power in order to operate.
