The three molten cores at Fukushima plant, each weighing a hundred tons, are so radioactive, that no one can approach them, including robots, which melt down immediately, Dr. Helen Caldicott, the 1985 Nobel Peace Prize nominee, physician and anti-nuclear advocate, states in an interview to Radio VR:
“And no one ever will, and the contamination will go on for hundreds of years,” Ms. Caldicott cites top physicists as saying.
Initially, TEPCO, the Japanese power provider wanted to erect an ice wall around the perimeter of the Fukushima complex, as ground water the underneath the reactor is absorbing radiation and then flowing into the ocean.
An ice wall is a silly idea given the circumstances, remarks the expert, as it would have to last at least a hundred years. Moreover, you would have to have electricity running all the time to keep the ground frozen, explains Ms. Caldicott.
