Background information on Fukushima
Arjun Makhijani, nuclear expert and President of the Institute for Energy and Environmental Research: Ground water is contacting the molten fuel and becoming extremely contaminated [...] The fuel is molten and the bottom of the reactor building is undoubtedly damaged. So that’s why the ground water flowing past the trenches and pipes and past the basement of the reactor building is getting into the reactor building where the molten fuel is. It may also be that the molten fuel is in the cracks of the foundation.
Associated Press: The turbine buildings at the Fukushima Dai-ichi plant are about 150 meters (500 feet) from the ocean. According to a Japan Atomic Energy Agency document, the contaminated underground water is spreading toward the sea at a rate of about 4 meters (13 feet) a month. At that rate, “the water from that area is just about to reach the coast,” if it hasn’t already, said Atsunao Marui, an underground water expert [...] on a government committee studying the contaminated water problem. “We must contain the problem as quickly as possible.”
