- 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.
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.
BBC News Asia-Pacific is now reporting that radiation levels inside the nuclear reactor are 1,000 times of normal, and there are now high levels (unspecified) ‘outside’ of the nuclear reactor plant. They report that people are being evacuated in an approximate 6-mile perimeter.
