Fukushima Daiichi still leaking radioactivity into Pacific Ocean. That expensive Ice wall turned out to be a slushy. Keep trying. Better yet, shut down before meltdown.

More than seven years after the March 2011 Fukushima nuclear crisis, radioactive water is continuing to flow into the Pacific Ocean from the crippled No. 1 plant at a rate of around 2 billion becquerels a day, a study has found.

The amount of leaking cesium 137 has decreased from some 30 billion becquerels in 2013, Michio Aoyama, a professor at the Institute of Environmental Radioactivity at Fukushima University, said in his study, which was presented Wednesday at an academic conference in Osaka.

The study said the concentration of radiation — 0.02 becquerel per liter of seawater found…
