Spent fuel control status

Nuclear fuel can be used to generate nuclear power for three to five years. After it is used up (it is now referred to as spent fuel), it is stored and controlled in spent fuel pools at the power station. The Hamaoka Nuclear Power Station has 6,625 spent fuel assemblies in storage as of October 2011.
