TEPCO Improves Core Cooling for Fukushima Daiichi Reactors

Industry/Regulatory/Political Issues

Plant Status

  • Tokyo Electric Power Co. says it has begun to increase the flow rate of cooling water into Fukushima Daiichi reactors 2 and 3 using the core spray method, which the operator says is successfully decreasing the reactor temperatures. Earlier this month, TEPCO began using the core spray system to inject cooling water from above the uranium fuel rods as well as from the sides and bottom using normal cooling water supply systems. As of Friday morning, the bottom of reactor 2 measured 114 degrees Celsius, reactor 3 was 103 degrees C, and reactor 1 was 85 degrees C. TEPCO plans to bring all three reactors below 100 degrees C by January.
