The New York Times quotes Kuni Yogo, a former atomic energy policy planner in the Japan Science and Technology Agency, as saying regarding the Fukushima Daiichi nuclear power plant: “There is some trial and error, but this is the beginning of a three- to five-year effort” required to continually cool the hellishly hot, melting reactor cores at reactor units 1, 2, and 3. Given the large-scale radioactivity releases that such activities have already released into the environment in the first three weeks of the Fukushima nuclear disaster, that could represent catastrophic radiation releases into the environment over time.
