Worst Case Scenario for Nuclear Explosion

1. Worst case scenario (reactor explodes) problems would only affect a 30 km radius around the plant.
2. No health problems expected outside this 30 km area. Today’s reports of increased radiation in Tokyo are trivial. The increase in radiation they are reporting is not significant. It would need to be 100s of times that level to cause any problems.
3. An allowable dose would be 100 times the background radiation.
4. They can monitor radiation levels in the area from outside Japan, so there is no cover up going on. Conspiracy theorists stand down.
5. In Chernobyl the top blew off the reactor and then the core caught fire and burnt. This convection pushed all radioactive material higher and higher into the air where it reached 30,000 feet and so the spread was much larger.
Here, a build up of pressure as the radioactive material interacts with the containment floor would cause an explosion that would only reach as high as around 500 meters. This would contain any dangerous material within the 20 to 30 km exclusion zone.
6. If all attempts at cooling the reactors fail, a worst case scenario, then there would be an explosion, but this blast would only throw radioactive material up to 500 meters, and the 30 km containment zone stands.
7. Acceptable levels of radiation are based on the most susceptible members of society (children and pregnant mothers). So right now, the levels outside the 30 km zone are fine for all members of society.
8. No matter how strong the wind, the radioactive material released after an explosion of the core wouldn’t make it to Tokyo.
