You run the pumps before the reactor starts up and after it shuts down. You use the electricity from one of your other nuclear reactors to do this. Electrical power is easier to pass around than steam power.
If you are thinking about running a steam turbine on primary reactor coolant remember that it is highly radioactive.
Inject some halon or something. Or use big fans to disperse the gas.
The first day of the accident, when they were running on batteries, they should have got another generator in there and hooked it up. It's a week later and they are just now doing that. Now they have to dig through rubble and endure massive doses of radiation.
Putting the electrical switching equipment below sea level in a tsunami prone area was pretty stupid, too.
There should be a regulation to have a backup generator 50 miles away that can be air dropped into the reactor site. There should be connections already in place for hooking it up.
In the context of the Fukushima Daiichi nuclear disaster, what if you could cover the overheating nuclear fuel with liquid aluminum? Aluminum is a good conductor of heat so that you could spray the surface with sea water to avoid melting. Would this solve the problems of decay heat and hydrogen generation? What if you alloyed the aluminum with neutron poisons such as hafnium or cadmium? Any other suggestions of something that you could cover the nuclear plant with to mitigate the problem?
LD50 for isobutanol is 2460 mg/kg.
The orally lethal dose in humans of pure ethylene glycol is approximately 1.4 mL/kg.
"Higher" alcohol usually means that it has more carbon atoms --- 4 in this case vs. 2 for ethanol.
I would say that isobutanol is a "better" alcohol for fueling cars than ethanol because it has a higher energy density, doesn't evaporate as much and doesn't suck water out of the air.
