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.
