Fukushima Power System Failure Takes Down Ice Wall & Nitrogen Injection

The power system to operate the freezing of the ice wall and also the nitrogen interting system for the damaged reactors failed early in the morning of July 28th. Ten hours later NHK reported that the two systems were back online using a different power system.  The frozen wall takes a longer time frame to begin thawing out. It isn’t clear yet if the halt of nitrogen injection impacted the reactors. TEPCO now reports that a landscaping pin was the cause of the power failure.

Fukushima Daiichi’s Little Known Hydrazine Problem

Fukushima Daiichi’s Little Known Hydrazine Problem

Recent Roadmap reports on activity at the plant have shown that hydrazine is still in use. The chemical was used in 2011 in an attempt to combat corrosion in the reactors and spent fuel pools. It is an oxygen scavenger, this may have been an additional reason for using this additive beyond the anti-corrosion benefit. Hydrazine has been well identified as a toxic chemical harmful to humans and the environment. Japan has had their own reporting rules … Read entire article »

SimplyInfo.org; Fukushima News Roundup, July 12, 2015

  NRA has begun work to consider BWR (boiling water reactors) for potential restarts. The initial push for restarts has focused on newer PWR units. All of the reactors involved in the Fukushima disaster at TEPCO’s two plants there were BWR units. The disaster proved a long list of design flaws and operational shortcomings that contributed to the disaster. This initial inspection process on BWR units is limited as seismic safety issues have yet to be addressed. This move will likely create considerable criticism since many of the root causes and damage outcomes from the Fukushima disaster are still not fully known. In the same week NRA began considering BWR reactors for restarts, Japan’s nuclear power companies asked that 40 year life limits for reactors be reconsidered. They want the rule changed … Read entire article »
