People are only worried about the incline of the reactor 4 building or seismicity, but I’m not really concerned about that though I’m not optimistic either. What concerns me more is that reactor 4 was being under the major remodeling construction when 311 happened.
For the remodeling construction, the pipes to connect to Reactor Pressure Vessel (RPV) inside of the drywell were cut off, and they were temporarily closed to wait for the replacement. It’s merely briefly welded to temporarily close, I’m worried that furnace water may leak from those pipes anytime.
