Why is Japan dumping radioactive water into the ocean?
Radioactive water continued to drain from the damaged Fukushima Daiichi nuclear plant into the Pacific Ocean on Monday, as Japanese officials mounted a desperate effort to find and plug the source of the leak.
On Saturday, the Tokyo Electric Power Company (TEPCO) thought it had discovered the leak’s headwaters – a crack in a concrete pit near reactor No. 2. TEPCO workers poured concrete into the pit to close the breach, but the leak continued.
