Tepco released the video of the SFP of reactor 4.
They took the video on 2/9/2012 to make a plan to take out the debris over the fuel racks.
NHK reported the degree of clearness was 5m, but all the other important information,such as the radiation level, temperature, nuclides, the state of the pool were not reported.
They didn’t even report “5m of degree of clearness ” is enough to take out the debris or not.
Tepco asserted there is no damage to the fuel assemblies. They are planning to do the video research a couple of time next month.
Note : Does anyone know how many fuel rods are in a fuel assembly ?
