Tokyo Electric Power Co. will have to change its road map for stabilizing the Fukushima No. 1 power plant because it will take longer than expected to install a cooling system with circulating water for heavily damaged reactor No. 1, experts said Friday.

The utility is still pumping massive amounts of water into the vessels to cool the fuel rods inside the pressure vessel.
