From Huntington News:

Although the initial accident took place in the Spring, the reactors at Japan's Fukushima nuclear plant again have mounting pressure from hydrogen. Workers are trying to reduce the pressure by spraying nitrogen. Should hydrogen levels go too high, additional explosions could occur. This Youtube video is based on a release from Toyko Electric Power.

In late October, Tokyo Electric Power Company began extracting gases from the containment vessel of the No.2 reactor to remove radioactive substances. During the work, TEPCO found hydrogen accumulating in parts of the reactor at a density of up to 2.9 percent.

TEPCO started pumping nitrogen into the pressure vessels of the No.1, 2, 3 reactors on Thursday to lessen the concentration of hydrogen.

The density of hydrogen accumulating in the containment and pressure vessels is thought to be below 4 percent, the level where an explosion could occur.

From the Wall Street Journal:

More than eight months after disaster struck at its Fukushima Daiichi nuclear plant, Tokyo Electric Power Co. said an internal investigation, its first public assessment of its handling of the crisis, found no evidence of significant errors in its response.

But the plant operator also conceded it still didn't have answers to some key questions about the disaster, in the latest reminder of how little is still known about how the March 11 accident unfolded and what the current status of the plant is.

The findings were part of an interim report on the accident that Tepco released Friday.

The report supports Tepco's line that its plant complied with earthquake safety standards. But Tepco acknowledged it hasn't yet resolved a fundamental problem: pinpointing the source of continued leaks of irradiated water from the plant. It also said it doesn't know why radiation releases spiked four days into the crisis.

Complicating the picture, the utility retracted an earlier statement that an explosion took place in Unit 2 of the plant on March 15, the day of the radiation increase, removing one possible cause for the higher radiation levels. Tepco initially said there were two explosions on March 15, one believed to be inside the suppression chamber of Unit 2 and another near the rooftop of Unit 4. This followed explosions at Unit 1 on March 12 and at Unit 3 at March 14.
