NCNUKE has received an update from GE Hitachi headquarters in Wilmington NC.  It contains very insightful information.  Read their press release and NCNUKE’s take on it below.

Japanese Cabinet Secretary Yukio Edano reported that the approximately 50 workers who had been working on cooling the crippled reactors at Fukushima Daiichi had been temporarily withdrawn.  A sudden spike in radiation levels caused the safety measure.  As always we at ncnuke will try to break down some of this information for our readers.

We at ncnuke have been going over the press release issued by GE Hitachi spokesman Michael Tetuan in order to give our readers some insight.    It indicates that the reactors funtioned well through the historically intense earthquake.  The tsunami was responsible for damaging the diesel powered backup generators, resulting in the power failure.  The press release indicates specifically one very interesting class of assistance.   Continue reading

The influential Washington based think tank , The Institute for Science and International Security;  states that the situation in Japan is more serious than the International Nuclear and Radiological Events Scale (INES) present rating of 4 out of 7.  They claim the scale should now rate the disaster as a 6 out of 7.  And that it may need to be rated as a 7 out of 7.  We will give are readers a breakdown of the scale.

Some background for our readers.  Fuel rods are removed from a reactor during the refueling process.  The old rods that are removed are referred to as spent fuel.  These rods, although no longer optimal for producing electricity in a reactor are still highly radioactive and filled with energy.  This spent fuel has long been the biggest problem in the electrical industry.

This is to advise our readers that NCNUKE has urged the State Department to send the Kaman K-Max unmanned helicopter to Japan.  Kaman along with Lockheed has been testing this heavy lift design for years.  It can lift 6000 lbs.  Can be operated remotely, and could be used virtually around the clock.  See the links below.

NCNUKE readers have been ahead of the blast damage aspect of the nuclear disaster in Japan.  Three explosions at Fukushima Diiachi reactors #1, and 3 have no doubt caused the raising radiation levels.  A more hostile and dangerous work environment would be hard to imagine.  Now the Tokyo Electric Power (Tepco) the plants operator is talking about using seawater dropped by helicopter to cool the damaged reactor!   It is a clear sign of how desperate the Continue reading

     In order to give our readers an insight into the problems associated with the nuclear disaster at Fukushima;  a little background is required.  Radiation exposure safety levels are not just a function of the intensity of the radiation that a person is exposed to.  It is also a function of the length of time a person was exposed.  Previously we used this analogy.  The person being exposed is like a large sponge in a empty sink.  The water is like the radiation.   A spigot on full force for a brief time will saturate less than a slow steady stream over a much longer time.  Continue reading

Despite the unfolding tragedy in Japan.  GE Hitachi in Castle Hayne is reporting that all 44 workers are safe.  They are arranging for their safe return.  When a reactor needs service the utility brings in off site technicians to expedite the labor intensive work.  Jobs such as refueling and repairs require many more people than the utility has on staff.  This is because

The Japanese nuclear safety agency has declared the Onagawa nuclear site safe after reports of raised radiation levels.  Japanese experts state that the raised levels of radiation were caused by the radioactive steam released at the troubled neighboring Fukushima site.
