Sentences with phrase «controlled nuclear reaction»

The basic principle behind a nuclear reactor is simple: the heat produced by a controlled nuclear reaction is used to create steam pressure that drives a power - generating turbine.

Not exact matches

The anniversary of the first controlled nuclear chain reaction marks an achievement of immigrants who served America in World War II.

Nuclear reactors often use deuterium oxide to control reactions, because the liquid slows down neutrons without capturing many.

They called this 20x6x25 - foot setup Chicago Pile Number One, or CP - 1 for short — and it was here they obtained world's the first controlled nuclear chain reaction on December 2, 1942.

Figuring out how to create and control the nuclear chain reaction was the foundation for the 448 nuclear reactors producing energy worldwide today.

The science has come a long way since Szilard's vision and Fermi's proof of a controlled nuclear chain reaction.

As a result, the nuclear chain reaction in their Chicago experiment could have spiraled out of control, with potentially devastating results.

In case of an accident, multiple systems would keep cooling water flowing to the core, and control rods would quickly drop, automatically shutting down the nuclear reactions.

When the reactor malfunctions or when operators need to shut off the reactor for any other reason technicians can remotely plunge control rods into the reactor core to soak up neutrons and shut down the nuclear reaction.

Finally, Bergeron summed up the events so far: «Based on what we understand, the reactor has been shut down, in the sense that all of the control rods have been inserted — which means there's no longer a nuclear reaction.

Circular cracks had formed around several of these steel nozzles in the corroded lid that shield the control rods — 20 12 - inch -(30 - centimeter --RRB- long sticks made of a silver — indium — cadmium alloy that are used to dampen or shut down a nuclear reaction — rendering them vulnerable to simply popping off.

The control of nuclear fusion — the reaction that powers stars and hydrogen bombs — would permanently solve the world's energy problems, not to mention a few geopolitical ones.
