(CNN) -- We are all deeply saddened by the news of the terrible devastation, destruction and death that occurred in Japan on March 12 from the incredible destruction brought on by a 9.0-magnitude earthquake and resulting tsunami. As if this were not enough, on the heels of these two events, several large nuclear power plants are in severe peril.

The dire events unfolding stem from a station blackout at the 40-year-old Daiichi nuclear plant in Fukushima initiated because of a tsunami-related failure of a number of redundant backup safety generators to power auxiliary cooling systems.

While the nuclear fission reactions liberating heat for power generation were stopped immediately from a reactor "SCRAM," many of the products of fissioning uranium-235 atoms are nuclides that are radioactive (radioisotopes) and they undergo nuclear decay typically in a chain of progeny that emit radiation that ends up as heat.
