People Also Ask about

What is it called when a nuclear reactor shuts down?

In commercial reactor operations, this type of shutdown is often referred to as a "scram" at boiling water reactors, a "reactor trip" at pressurized water reactors and "EPIS" at a CANDU reactor. In many cases, a scram is part of the routine shutdown procedure which serves to test the emergency shutdown system.

What are the failures of tin whiskers?

To date, there are reports of at least three tin whisker induced short circuits that resulted in complete failure of on-orbit commercial satellites. There have also been whisker-induced failures in medical devices, weapon systems, power plants, and consumer products.

How long does it take to shut down a reactor?

If the reactor was operated within the last 24 hours then it can be restarted in less than 2 hours. It takes less than 1 second to shut down the reactor and another hour to perform the normal shutdown valving and checks.

What is the shutdown button on a nuclear reactor?

Scrams are usually activated or “tripped” by electronic means through some of the hundreds of safety sensors and systems of modern nuclear reactors, but they still have a manual scram. Once this is initiated it occurs in fractions of a second.

What does stalling a reactor mean?

A reactor can be unintentionally "shutdown" by having an excess of neutron poisons in the reactor vessel. Neutron poisons are chemical byproducts of the nuclear reaction which absorb neutrons, lowering reactivity in the reactor and potentially stalling the reaction if enough poisons are allowed to build up.

What is a nuclear reactor emergency shutdown called?

Scram is the term used by nuclear engineers to describe a rapid emergency shutdown of a nuclear reactor.

What is the word for nuclear shutdown?

The word “scram” is commonly used in place of “trip” in reactor operation; in fact, Webster's Ninth New Collegiate Dictionary defines scram as “a rapid emergency shutdown of a nuclear reactor.” No origin of the word is provided.

What is the name of the shutdown of a nuclear reactor?

In commercial reactor operations, this type of shutdown is often referred to as a "scram" at boiling water reactors, a "reactor trip" at pressurized water reactors and "EPIS" at a CANDU reactor. In many cases, a scram is part of the routine shutdown procedure which serves to test the emergency shutdown system.
