No, I only indicated what the concern would be if the core and primary system heated to the point that the primary system would be over-pressurized. Outside of the primary system, which includes the pressure vessels that contains the core, is the containment building. The containment building is designed to contain the contents of the primary system, and radioactive material, in the even the primary system leaks. However, we prefer not to allow the primary system to be compromised.
I have not yet heard any report on the integrity of the pressure vessels of priamry system of any of the units. I would not be obvious from satellite or air.
I am waiting for reliable information.
This map shows the locations of Japanese NPPs.
The Fukushima plants 1 and 2 were the closest, but Tokai and Onagwa are also affected. They should have all units shut down.
Fukushima Daiichi (Plant 1) has 6 units, and Fukushima Daini (Plant 2) has 4 units. Tokai has 2 units and Onagawa has 3 units.
