A Third Explosion Tuesday Morning North of Tokyo at Fukushima Nuclear Plant

A third explosion has been reported at Fukushima Daiich plant Nuclear Reactor Site #2. An explosion was heard after 6:10 JST on 15 March in unit 2, and the pressure-suppression system might have been damaged. Many more employees have been evacuated. There is no definitive report of exactly what happened. One-half of a fuel rod is reported to be exposed. On Tuesday morning Japan Time, Unit 2 was reported to be in the most critical condition of the reactors.

The last line of defense is the containment vessel. The concern is that the containment vessel at Reactor Site #2 may have been breached.

There is a sudden increase in radiation at a town directly south of the Fukushima plant.

At 11:15 JST on March 14 2011, an explosion of the building surrounding Reactor 3 of Fukushima 1 occurred, presumably due to the ignition of the built up hydrogen gas. The Fukushima Daiichi’s reactor 3 injured 11 people and destroyed the building surrounding it. The explosion was felt 40km (25 miles) away and sent a huge column of smoke into the air.

The first blast was at Reactor 1 on Saturday. At 15:36 JST on March 12, 2011 there was an explosion at Unit 1. Four workers were injured, and the upper shell of the reactor building was blown away leaving in place its steel frame. The container of the reactor remained intact.
