Fukushima's tankfuls of tainted water force tough call on dumping

Pouring diluted tritium into sea would trigger backlash, but space is tight

TOKYO/FUKUSHIMA, Japan -- Space for storing treated but still radioactive water is running out at Japan's crippled Fukushima Daiichi nuclear power plant. Soon, the government and utility Tokyo Electric Power Co. Holdings will have to make a decision: Should they dump the water into the sea? 

About 1 million tons of treated water is being kept in tanks at the site. Within three years, there is likely to be no room left for additional tanks. A solution to the ever-growing amount of water must be found so that the decommissioning of damaged reactors can proceed.
