Current Status at 3 Mile Island
Today, the TMI-2 reactor is permanently shut down and 99% of its fuel has been removed. The reactor coolant system is fully drained and the radioactive water decontaminated and evaporated. The accident's radioactive waste was shipped off site to an appropriate disposal area, (there is no such thing as disposal, it just stored somewhere) and the reactor fuel and core debris was shipped to the Department of Energy's Idaho National Laboratory, (a place with yearly storage/leakage problems).
In 2001, First Energy acquired TMI-2 from GPU. First Energy has contracted the monitoring of TMI-2 to Exelon, the current owner and operator of TMI-1. The companies plan to keep the TMI-2 facility in long term, monitored storage until the TMI-1 plant ceases operations, at which time both plants will be decommissioned (and become permanent radiation contamination zones).
In reality, 3MI just missed becoming America's version of Chernobyl....
By early morning, the core had heated to over 4,000 degrees, just 1,000 degrees short of meltdown. In the meltdown scenario, the core melts, and deadly radiation drifts across the countryside, fatally sickening a potentially great number of people. The reactor had come within less than an hour of a complete meltdown. More than half the core was destroyed or molten, but (thank God) it had not broken its protective shell.
Two days later, however, on March 30, a bubble of highly flammable hydrogen gas was discovered within the reactor building. The bubble of gas was created two days before when exposed core materials reacted with super-heated steam. On March 28, some of this gas had exploded, releasing a small amount of radiation into the atmosphere. At that time, plant operators had not registered the explosion, which sounded like a ventilation door closing. After the radiation leak was discovered on March 30, residents were advised to stay indoors. Experts were uncertain if the hydrogen bubble would create further meltdown or possibly a giant explosion, and as a precaution Governor Thornburgh advised “pregnant women and pre-school age children to leave the area within a five-mile radius of the Three Mile Island facility until further notice.” This led to the panic the governor had hoped to avoid; within days, more than 100,000 people had fled the surrounding towns.
If Cold Fusion ever happens, then I might go for that, but nuclear fission is a disaster waiting to happen, while generating a steady stream of toxic radioactive wastes. No thanks to that....
