Entry Img

A Level 7 Incident After the explosion involving reactor facility 4, the decision was made to evacuate all ďnon-essentialĒ personnel and 650 workers left the site, leaving just 70 to continue the stabilization work. In addition to the three reactors, there was also concern that the spent fuel pools might be losing water thus allowing […]

Fukushima: Lessons Learned (Part Four)

Explosions As March 12th dawned the reactors continued out of control with the plant largely reliant on the built-in design safeguards to cope with surging pressures and temperatures. †There was a vital need for electricity so that operating parameters could be observed and maintained, if possible.† In addition, aligning valving for water injection or controlled […]

Fukushima: Lessons Learned (Part Three)

Entry Img

Flying Blind The incoming tsunamis, much larger than planned for, had destroyed back-up electrical generation capability when the diesel generators were swamped and electrical switch gear wetted.† Electricity was vital in order to monitor the conditions within the reactor vessels and to take actions to prevent a catastrophic event. Plant personnel were now faced with […]

Fukushima Nuclear Power Plant The plant is located on the northeast coast of Japan about 120 miles from Tokyo. †It consists of six (6) GE-designed Boiling Water Reactors. †The steam energy from the boiling water is used to drive turbines which create electricity. †The steams cools and condenses back into water for re-use.††The 860-acre site […]

My thoughts and feeling about the memorials and behaviour have also evolved. I pretty much gauge my outlook on how visitors from that time (Korea and Viet Nam vets, members of the Greatest Generation, etc.) would expect and regard the behaviour. Sitting on the ledge unobtrusively dipping one's toes is not especially disrespectful. Kicking water…

As a democrat, I whole-heartedly support Trump exercising his first amendment rights. Frankly, his free speech is he best thing the Democrats have going for them coupled with the hypocracy of the Republicans and their tea party/evangelical base. I love that Republicans who criticized Clinton for dodging the draft have no problem when it is…
