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

every day the reactor is down and not making electricity costs the utility a fortune.  Also radiation exposure is a function of not only the amount of radioactivity one is exposed to;  but also the time of the exposure.  Think of of a large sponge under a spigot.   A trickle overnight will saturate the sponge more than if the spigot was  open full force for a fraction of a second.  our bodies act in a similar fashion as the sponge.
