– Nuclear Engineer: New footage shows Reactor 1 has “ruptured” containment structure, most likely from the explosion — Water to cool “what’s left of core” flowing into environment (VIDEO) (ENENews, Nov 15, 2013):
The Japan Times, Nov. 14, 2013: One leak came from a rupture in a sand-cushioned drain pipe installed at the bottom of the containment vessel.
Chris Harris, former licensed Senior Reactor Operator and engineer, Nutrimedical Report, Nov. 14, 2013 (at 29:00 in): They did indeed find water pouring out of several locations in Reactor 1?s containment structure and basically this shows that it was ruptured, most likely during the explosion that happened […] As we discussed before, all the water that gets pumped in to cool what’s left of the core […] it goes in and it’s falling back out again and goes right into the secondary side, which is basicallly the reactor building […] Because the water level’s not going up into that part of the building, it’s flowing out into the environment. That’s not really good news.
