On January 3, 1961, nine days after
Christmas, Richard Legg, John Byrnes, and Richard McKinley were killed in a
remote desert in eastern Idaho. Their deaths occurred when a nuclear reactor
exploded at a top-secret base in the National Reactor Testing Station (NRTS).
Official reports state that the explosion and subsequent reactor meltdown
resulted from the improper retraction of the control rod. When questioned about
the events that occurred there, officials were very reticent. The whole affair,
in fact, was discussed much, and seemed to disappear with time.
In order to grasp the mysterious
nature of the NRTS catastrophe, it help to know a bit about how nuclear
reactors work. After all, the generation of nuclear energy may strike many as
an esoteric process. However, given its relative simplicity, the way in which
the NRTS reactor functions is widely comprehensible. In this particular kind of
reactor, a cluster of nine-ton uranium fuel rods are positioned lengthwise
around a central control rod. The reaction begins with the slow removal of the
control ro, which starts a controlled nuclear reaction and begins to heat the
water in the reactor. This heat generates steam, which builds pressure inside
the tank. As pressure builds, the steam looks for a place to escape. The only
place this steam is able to escape is through the turbine. As it passes through
the turbine on its way out of the tank, it turns the giant fan blades and
produces energy.
On the morning of January 3, after
the machine had been shut down for the holidays, the three men arrived at the
station to restart the reactor. The control rod needed to be pulled out only
four inches to be reconnected to the automated driver. However, records
indicate that Byrnes yanked it out 23 inches, over five times the distance
necessary. In milliseconds the reactor exploded. Legg was impaled on the
ceiling; he would be discovered last. It took one week and a lead-shielded
crane to remove his body. Even in full protective gear, workers were only able
to work a minute at a time. The three men are buried in lead-lined coffins
under concrete in New York, Michigan, and Arlington Cemetery, Virginia.
The investigation took nearly two
years to complete. Did Byrnes have a dark motive? Or was it simply an accident?
Did he know how precarious the procedure was? Other operators were questioned
as to whether they knew the consequences of pulling the control rod out so far.
They responded “Of course! We often talked about what we would do if we were at
a radar station and the Russians came.
“We’d yank it out.”
Official reports are oddly
ambiguous, but what they do not explain, gossip does. Rumors had it that there
was tension between the men because Byrnes suspected the other two of being
involved with his young wife. There is little doubt than he, like the other
operators, knew exactly what would happen when he yanked the control rod.

Many people like to eat pizza, but
not everyone knows knows how to make it. Making the perfect pizza can be complicated,
but there are lots of ways for you to make basic version at home.
When you make pizza, you must
begin with the crust. The crust can be hard to make. If you want to make the
crust yourself, you will have to make dough using flour, water, and yeast. You
will have to knead the dough with your hands. If you do not have enough time to
do this, you can use a prepared crust that you buy from the store.
After you have chosen your crust,
you must then add the sauce. Making your own sauce from scratch can take a long
time. You have to buy tomatoes, peel them, and then cook them with spices. If
this sounds like too much work, you can also purchase jarred sauce from the
store. Many jarred sauces taste almost as good as the kind you make at home.
Now that you have your crust and
your sauce, you need to add the cheese. Cheese comes from milk, which comes
from cows. Do you have a cow in your backyard? Do you how to milk the cow? Do
you know how to turn that milk into cheese? If not, you might want to buy
cheese from the grocery store instead of making it yourself. When you have the
crust, sauce, and cheese ready, you can add other toppings. Some people like to
put meat on their pizza, while other people like to add vegetables. Some people
even like to add pineapple! The best part of making a pizza at home is that you
can customize it by adding your own favorite ingredients
