PROBLEM IS ABOUT 120,000 TONS OF CONTAMINATED WATER As of 05 Jul 2011. Additionally, Cooling water has to be pumped into the plant at a rate of about 400 Tons /day to prevent the four(4) Nukes, and their spent fuel ponds from boiling and giving off transuranic (long-life radioisotopes) in steam and other exhalations(spews); THAT, IS WHAT MUST BE STOPPED ASAP.
Plant owner/operator Tokyo Electrical Power Co. (TEPCO) is required to inform Japan’s Nuclear and Industrial Safety Agency (NISA) of progress in the storage and treatment of water on a weekly basis until all the accumulated water has been transferred to storage facilities and treated.
A DOWNWARD TREND AT LAST. Until about a month ago, highly radioactive water has accumulated at Dai No. 1 until there is nowhere else to store it; Now however, a cooling water filtration system designed in collaboration between France’s Areva, and America’s Kurion Co. is in process of being optimized (“tweaked”), and has steadily improved to enable “recycling” of the cooling water. As of 29 Jun 2011, About 6,380 tons had been filtered, bringing the cumulative amount to 13,610 tons; This is important, because it indicates a downward trend in the accumulated radioactive cooling water total.
ADDITIONAL FILTRATION. The concentrated salt water from the operation will be treated in a 250 ton/day evaporative concentration plant, expected to start operation in August 2011. This will be able to generate up to 83 tons of fresh water per day, leaving 167 tons of concentrated salt water.
WORK IN PROGRESS TO PREVENT CONTAMINATED COOLANT “LEAKAGE” INTO THE SEA. A total of 109 concrete plates have been installed in the water intakes for the four units, forming a barrier against any leakage into the sea. The plates measure 1.4 x 4.42 meters, are 32 cm thick and weigh over 4.5 tons.
Most experts agree that containment, decontamination, and “recycling” of the coolant water is the key to stabilizing the three(3) melted-thru Nukes, and their “Spent Fuel Pools” over the long-term. PROBLEM IS: THE COOLING EFFORT COULD REQUIRE YEARS. TEPCO is going “ where no one has gone before”, and that isn’t good!
Still, it is good to be able to report ANY good news from the Fukushima Dai No. 1. Nuke Complex.
