Nuclear experts are casting doubt on Japan’s plans to build a giant underground “ice wall” surrounding the crippled Fukushima Daiichi nuclear facility in a bid to stop dangerous radiation leaks.
The roughly $320 million ice wall would theoretically function like an underground dam to stop groundwater from seeping into the facility where it becomes contaminated with radioactivity.
One of those questioning the ice wall is Dale Klein, former U.S. Nuclear Regulatory Commission Chairman and current head of the Nuclear Reform Monitoring Committee hired by plant operator TEPCO.
“I’m not convinced that the freeze wall is the best option,” he told Kyodo News. “What I’m concerned about is unintended consequences.”
“Where does that water go and what are the consequences of that? I think they need more testing and more analysis,” Klein said.
