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.

Authorities in Japan are now reporting that fuel rods are melting at the 3 crippled reactors.  Their containment vessels are still intact preventing a catastrophic radiation release.  It shows that Japanese authorities attempts to cool the reactors have failed so far.  They have reported that up to 180,000 have been evacuated.  Newer experimental reactor designs like Pebble Bed Reactor’s are virtually meltdown proof.  These older GE Mark 1 BWR require massive cooling  Continue reading

As we have discussed here before, The GE Mark 1 BWR (Boiling Water Reactor) has its root in the 1950,s.  Back then the engineers could not have imagined supporting this design in the year 2011.  It is sort of like trying to get a 1955 Chevy to meet all of todays safety and crash standards.  In fact GE has done a remarkable job.  It is also a testament to the sheer robustness of the design.

Japanese officials have confirmed that the core which houses the reactor at Fukushima 3 is intact.   As if nuclear experts in Japan did not have enough problems to deal with;  now blast damage is mounting.

      As the most powerful earthquake in 140 years struck Japan, experts from across the globe are eagerly awaiting the data.  It is a once in lifetime oppurtunity to make nuclear generation safer throughout the world.  This disaster also highlights the robustness of the safety systems, even on the older reactor designs.  Japan has embraced nuclear power due to it’s lack of natural resources and strong contruction and engineering business culture.  53 reactors provide Japan with 35% of its electrical power.  Making it the third largest nuclear power generating country on earth.
