At 9:53 AM on November 6, Unit 3 spent fuel pool alternative cooling system was stopped in order to check the change of visibility inside the spent fuel pool (clarity of the pool) during system suspension as a preparation for debris removal from the pool (The pool water temperature when the system was stopped: 17.5℃). The system will be suspended until November 10. Since the pool water temperature increase rate is estimated to be approx. 0.17℃/h and there will be a sufficient margin to the maximum allowed temperature of 65℃, there will be no problem with the pool water temperature control.
