TOKYO (AP) — A Japanese utility says fuel rods at a troubled nuclear reactor were once again fully exposed hours after authorities were able to stabilize a similar emergency.
Tokyo Electric Power Co. says the exposure happened at Unit 2 of the Fukushima Dai-ichi plant because a steam vent wouldn’t open Monday, causing a sudden drop of water.
That reactor and two others at the plant are dangerously overheating and authorities are racing to prevent meltdown.
