<TMI was a pressurized water reactor...>
I recall during the early morning of March 28, 1979 there was a sequence of improbable events that began to unfold. A water valve in the primary cooling system around the the nuclear core was accidently closed by a maintenance crew. An emergency backup system opened a pressure relief valve but later failed to close, resulting in the evaporization of the nuclear core's primary coolant. Thirdly, the control room operators failed to notice for several hours the dangerously elevated temperature readings registered by a gauge that was poorly located. The culmination of these mischances resulted in the uncontrolled release of thousands of gallons of radioactive water.

An estimated 150,000 people within a 15-mile radius of the plant left the area for nearly a week.

What an unfortunate tragedy as far as its devastating effects on the use of nuclear power in the United States. If it hadn't occurred, the nation's energy shortages today would likely be nonexistent.

Jim,

There is less radioactivity released from nuclear plants than from coal fired plants.

Yes, coal contains significant amounts of uranium which becomes concentrated in the ash.
