Japan’s nuclear safety agency has instructed the operator of the stricken Fukushima Daiichi nuclear power plant to check if hydrogen is building up in its No.2 and 3 reactors.

This is after the Tokyo Electric Power Company, or TEPCO, recently detected hydrogen in a pipe leading to the containment vessel of No.1 reactor. A hydrogen explosion occurred at the No.1 reactor on March 12th, after the March 11th quake and tsunami.

The government’s Nuclear and Industrial Safety Agency on Sunday instructed TEPCO to check pipes in the No.2 and No.3 reactors. The No.3 reactor suffered hydrogen explosion on March 14th and No. 2 reactor had a hydrogen explosion on March 15th.

The utility says it will measure the levels of hydrogen at the No.1 reactor before injecting nitrogen and taking other measures to prevent another explosion.

The firm is expected to take similar measures if hydrogen is detected at the No.2 and No.3 reactors as well.
