Gov’t assumed massive radiation exposure from Fukushima nuclear plant, Kyodo/AP, May 3, 2011:

The government assumed a worst-case scenario of “significant public exposure” to radiation [...] a day after the March 11 earthquake and tsunami, Kyodo News learned Tuesday.

The scenario assumed the container of the No. 1 reactor would be damaged [...] if the workers failed to reduce pressure within the containment vessel by venting steam [...]

The Nuclear and Industrial Safety Agency assumed that the failure to vent the steam could increase pressure inside the container to three times the design limit by 11 p.m. on March 12. The high pressure would break the container [...]

Reactor No. 1, March 12 at 3:36 pm in Japan:
