Japanese authorities have informed the IAEA that TEPCO has been authorized to begin injection of nitrogen into the primary containment vessel (PCV) of Unit 1 at the Fukushima Daiichi nuclear power plant. Injection of nitrogen is intended to displace oxygen inside the containment vessel, thereby reducing a risk of explosion due to the combustible combination of hydrogen and oxygen.
