How would a nuclear plant meltdown unfold?
Control rods are driven back down into the core upon emergency (if rods don’t make it all the way… trouble)
The coolant (water) could cease if backup systems fail (electricity, pumps, generators, batteries)
Reactor continues to produce heat
Numerous venting valve systems would release pressure above ~1,000 psi into containment vessel
Eventually the uranium fuel encasement metal will melt (2,200 deg F)
Radioactive contamination then released into the reactor vessel
Radiation escapes into an outer, concrete containment building
Radiation escapes into the environment.
Not only would such a disaster be horrible for the local region and Japan, but other countries, namely the U.S. would be effected next by airborne
radiation particles, the magnitude of which is yet to be determined.
Why would the west coast USA be in danger?
The prevailing jet stream winds are blowing from Japan directly across the Pacific ocean to the west coast of the United States. Any airborne
radiation would make its way across with the jet stream, reaching the U.S. in approximately 36 hours, depending on the actual speed of the jet.
