The operator of the crippled Fukushima Daiichi nuclear plant is racing to secure storage space for tainted rainwater as another typhoon bears down on the Japan, it’s projected path expected to take the storm to Fukushima.

Tokyo Electric Power Company (TEPCO) hasn’t dealt with the contaminated rainwater collected at the radiation-spewing site from the last typhoon a week ago.  There’s no more room left in the above ground series of storage tanks, so the contaminated water is being drained into three massive underground storage tanks that were disused earlier because they leak.  Those leaks are not repaired.  TEPCO says it has no other option.

TEPCO also says some of the radioactive rainwater overflowed a containment barrier in 11 locations.  The water seeped into surrounding soil, and part of it likely ran along a drainage ditch and reached the ocean.  TEPCO found 140,000 Becquerels per liter of Beta-ray emitting radioactivity in an onsite ditch on Wednesday.  The radioactivity has doubled since the previous day.  TEPCO says it is transferring the contaminated water to a tank.

Earlier this week, the utility admitted it had detected radioactive cesium one kilometer off the coast of the facility.
