Yes, I am very proud of Tyler.
But I am wringing my hands in agony, watching that nuclear plant blow up this morning... that whole area has to the potential to go all Chernobyl on them.
What a catastrophe.
Tyler is doing a very nesessary job in an extremely bad situation. I hope he and all the other rescuers will stay safe and wish them good luck in the days ahead.
I worked in the nuclear power industry and there is no possibility of these reactors going "Chernobyl" due to their inherent design. However, the problem is almost identical to Three Mile Island and the hydrogen explosion today was almost what happened at TMI when a hydrogen bubble formed at the top of the containment vessel.
My concern is that Japanese business have a bad reputation for not releasing information that can expose them in a bad light and I am wondering just how bad the situation really is.
My trade dealt directly with the testing and calibration of the safety shutdown systems so I have some knowledge in this area. According to some reports the Japanese units were relying on battery power for 9 hours before backup generators were available.
It is highly unlikely that the batteries lasted 9 hours since the batteries are only intended to maintain emergency power until backup generators can take over. This is usually rated at 30 minutes. According to news reports the normal backup generators failed after being drowned out by the tsunami. The batteries would then have been drained and the emergency cooling to the fuel in the reactors would have failed.
The long term backup generators where I worked were basically a jet engine coupled to a turbine generator set that produces 4 megawatts at 4160 volts. I doubt you have seen one of these at your local Home Depot. It takes that kind of power to cool down a nuclear reactor. Reports state that backup generators were brought in to restore power. You don't just plug in extension cords when you are dealing with this kind of power. It would have taken some time to make all the required connections.
Radiation leaks are being detected though reports don't mention the type of radiation (gamma, beta, alpha or neutron)
The radiation suits that nuclear workers wear only protect you against alpha & beta radiation. Neutron radiation is only present when fission is taking place. Gamma is controlled with shielding, distance from source and other factors.
One of the latest reports is that workers will be flooding the reactor core with seawater. It is highly likely that the resulting steam will need to be released and that this steam will be carrying radioactive components.
The hope is that the prevailing winds at the time will take the steam cloud out to sea where it will dissipate.
