Title: Survey on Distribution of Debris in Unit 4 Spent Fuel Pool, Fukushima Daiichi
Nuclear Power Station
Date: March 12, 2012
ROV*, which is controlled remotely and whose underwater camera is a self propelling is used for the survey on the distribution of debris in the spent fuel pool.
We will through ROV in SPF through the slit of floats covering the pool. We operate it from the operating floor.
We are considering to move control rods currently stored in the cask pit to the bottom of Reactor in the future when we take out the fuel in SPF [sic]. We will survey debris fallen down to the bottom of Reactor to organize the plan.
