we'd been cooling reactor 2, but because of hydrogen blast #2 reactor's water level started sinking. at this point, water had been 2 meter above the fuel rods but started sinking, pressure level within reactor had been stable at 6 mega-pascal but rose to 7 mega pascal so kind of showing not cooling enough, vapor started accumulating more, probable reason for water level drop, in order to respond:
1. at 4:34 pm we opened one vent but one more vent is still closed, if more pressure increases we will open 2nd vent 2. we will release into nuclear container & then into the outside 3. after that venting we hope cooling system will resume 4. if not we will use seawater
we never been using the seawater on #2 but we will be
the second reactor -- we been using just regular water, normal cooling system (prior to the hydrogen blast) but now we might have to use, right now we're following normal emergency protocol.
the reason regular cooling system is malfunctioning is because of pressure rise
if we add seawater we can enhance the cooling process & lower the vapor, we have that option
the priority is to make sure there is enough water, as long as supplied into the reactor i don't see any problem
there are several options like from the firetrucks but truck was damaged by hydrogen blast so if we need pump we will get it
tokyo scheduled blackout starting soon (correction, not tokyo, ibaraki & other areas)
this was official word from the japanese nuclear agency, about fukushima plant 1 (daiichi), reactor #2.
there was also more to the radiation monitoring but i didn't get there quick enough to type, but what i thought i understood was that they had been monitoring during/after the hydrogen explosion -- they'd asked people to stay inside afterward as a precautionary measure but they've lifted that, there was no endangering radiation rise associated with the blast.
i don't swear that's 100% accurate but that's the gist of what i thought they said.
they continue to evacuate people from the 20 km zone as a precaution.
