and WAIT!? you're saying their WAS NO CONTAINMENT BREACH you imbecile?!?!?!!.. where exactly are the cores then... GPS guesstimates?!?!!... LMAO... you fool no-one...

besides you asked for evidence about robotics and unit 1.. i'm still divulging... eat some non-irradiated rice.. speaking of which you do know that in Fukushima province in the town hall they record .1 Bqls... whilst in the schools.. for education purposes.. they eat 10x that amount... are you evil by nature or payed a lot? .. do you sleep at night.. i digress....

ABOUT THE UNIT 1 FAILURE OF ROBOTS:

"Radiation Hardening 101: How To Protect Nuclear Reactor Electronics

Tucked behind shielding, most of the electronics in a working nuclear reactor are no more exposed to radiation than the humans that operate them. Problems like the loss of coolant in Japan’s damaged Fukushima reactors can change that, boosting radiation to levels that can threaten control systems and robots that might be sent in for repairs.

How do you protect or “harden” electronics to prevent radiation damage? And are the electronics at the Fukushima Dai-1 nuclear power plant tough enough? IEEE Spectrum Associate Editor Rachel Courtland asked Dan Fleetwood, an expert in radiation-resistant devices at Vanderbilt University in Nashville, Tennessee, to take us through the basics.

How does radiation pose a problem for electronics?

Radiation can ionize atoms and disrupt a semiconductor’s crystal structure. For electronics that are very close to a reactor, neutrons will create physical damage to the semiconductor crystal. But most chips will fail first because of leakage that’s associated with the charging of insulators. In something like a metal-oxide-semiconductor device, for example, gamma rays and X-ray radiation will knock electrons off atoms in an insulator to create electron-hole pairs. The resulting trapped positive charges will shift the operating characteristics. Devices are designed to turn on and off at a well-defined point of operation, and if that operating voltage shifts, this can create difficulties.

How do you protect or “harden” electronics against radiation in a nuclear reactor?

It involves all aspects of design, process, and testing. At a power plant there are usually design criteria to keep the most basic operating and control electronics relatively simple and relatively robust so that you can have an event like a loss of coolant and maintain control of the plant."
