Meanwhile in TEPCO land in Fukushima, it's a steady stream of slowly degrading systems and equipment that were hastily assembled last year.
According to TEPCO's plant status report on June 19, 2012 (Japanese only; there is no English version), a TEPCO worker noticed a hissing sound coming from the flexible duct from the Reactor 3 Containment Vessel Gas Management System on June 19 at about 12:19PM. The Gas Management System is located on the 1st floor of the Reactor 3 turbine building. The duct had been damaged for some unknown reason, and TEPCO says the damage has been temporarily patched up with tape while the cause is being investigated. The company says there has been no effect on the pressure inside the Containment Vessel, the amount of hydrogen gas inside the CV, or the amount of gas flowing through the Gas Management System.
