Tepco announced they measured hydrogen gas in the pipe to the containment vessel of reactor 2 as well.
“According to Tepco” ,it was 6.5 %.
However,4% of hydrogen and 5% of oxygen cause hydrogen explosion.
It’s enough to cause another hydrogen explosion.
They are planning to use a filter to eliminate radioactive particles in the pipe. They are going to try to reduce hydrogen after installing the filter.
