According to KEPCO, at Takahama Unit 4 PWR (pressurized water reactor) in Japan an alarm indicating “caution on the primary system floor drain” went off at 15:42 on February 20, 2016. The operator conducted a field inspection and found a radioactive puddle on the floor in front of the condensate demineralizer (filtering system which uses resins to eliminate impurities from the reactor coolant) in the reactor auxiliary building. Leaked radioactive water was also collected by the auxiliary building sump and other components. The total leakage was an estimated 34 liters with a total amount of radioactivity of 60,000 Becquerels (Radioactive disintegrations or shots per second.) This would be 1,764 Bq per liter. (See original English KEPCO press release at bottom).

What caused the leak? Valve Problems, of course
