Fukushima Daiichi - Update


A minuscule amount of radioactive iodine was detected in milk in Spokane, Wash., the U.S. Environmental Protection Agency reported.  The agency said the level detected—0.8 picocuries per liter—is more than 5,000 times lower than the level that would prompt any action by the U.S. Food and Drug Administration to pull milk from grocery stores. “These types of findings are to be expected in the coming days and are far below levels of public health concern, including for infants and children,” the EPA said. The EPA has increased its nationwide monitoring of milk, rain water and drinking water.

Fukushima Daiichi

Tokyo Electric Power is increasing its efforts to remove radioactive water that has pooled inside concrete vaults that house pipes near the reactors at the Fukushima Daiichi nuclear plant. Maintaining cooling water flow to the reactors and used nuclear fuel storage pools and containing and removing the contaminated water continue to be priorities for workers at the site.

Contaminated water was found in the basements of the turbine buildings at reactors 1-4 and in the concrete vaults outside the buildings. Workers finished pumping water from the reactor 3 turbine building and are removing water from reactor 1 tunnel into a storage tank. Today, TEPCO has been pumping contaminated water from the reactor 2 turbine building into a storage tank.

Freshwater injection continues to cool reactors 1, 2, and 3. The company also is spraying cooling water into the used nuclear fuel storage pools at reactors 1-4.

The key is to not confuse potential meltdown (very unlikely now, either in containment or spent fuel pools) with radiation due to the activities that have occurred to date to protect from a worse situation.

  1. There is virtually no risk of meltdown and they seem to be quickly and adequately containing all existing contamination. Let's just hope that now new leaks or breaches develop. If there were another earthquake and tsunami while this site is in a vulnerable state, it seems there could be much worse risks on our hands!
