8.5 Tonnes of Water Leaked from Reactor Well/Spent Fuel Pool of Reactor 4 According to TEPCO

In the evening press conference on February 1, 2012 (with Matsumoto), TEPCO announced the result of their calculation: 8.5 tonnes of water from the Reactor Well/Spent Fuel Pool of Reactor 4 may have leaked (Jiji News, Japanese, 2/1/2012). Other than the information of the TEPCO's calculated number and the diameter of the pipe (9 millimeters), the details seem the same as I reported in my previous post.

Just keep in mind that that's their calculation for about 29 hours from 3:50PM January 30 to 10:43PM January 31.

TEPCO also released the photographs of the jet pump test line that leaked; one pipe is totally dislocated from the joint.
