Reply #298: building 3 external water cooling systems onsite

[divvy]

It sounds like they are going to start building 3 external water cooling systems onsite. That seems like an imperative to me, because of 1) high radiation in U1-3 facility will make restoration of core cooling difficult, 2) they have to stop dumping so much water into the site for cooling, because the more that goes in, the more nasty water that will have to be released or stored. I read in some stories that they are going to inject nitrogen into some containments... and some say they are going to inject it into reactors... so I am confused... they aren't the same. Exelon has sent a technical team to Japan... an engineer from the plant I worked at has left for Japan. Contamination is spreading pretty badly in Japan... a city outside the evacuation zone as been instructed to evacuate. China, South Korea, and other nearby countries are starting to get more concerned as the crisis seems to continue without a lot of apparent progress to get it under control. You know that radioactive water leak that was flowing out of the crack? That was coming from the turbine building... they need to figure out how that is happening. This is really nasty stuff from the reactor or spent fuel pools... neither are in the turbine building (TB). How did it get there? They need to get their arms around how so much water is flowing to the turbine building. Flooding the TB could make it impossible to get RHRSW (service water for core cooling) running. This leak is large enough that it needs to be stopped... in a week you could have the large rooms filled with this very nasty water. The more water that leaks... the more you have to inject. This is important... that was a lot of very, very contaminated water. It is still accumulating in the TB
