keff is defined as the neutrons in one generation due to fission divided by the neutrons from the previous generation. The denominator includes the source neutrons. Thus it is the fractional change in neutron population.

What does scram mean for a nuclear reactor?

In dealing with a nuclear reactor SCRAM stands for Safety Control Rod Activator Mechanism. Nuclear reactors can be quite dangerous.


How many methods are there to give heat to the reactor?

If you mean a nuclear reactor, and not a chemical one, there is only one way, and that is by nuclear fission in the fuel


What is retentivity in nuclear energy?

You may mean 'reactivity'. In a nuclear reactor, this is the measure of how much above or below criticality the reactor state is, which effectively determines how fast the neutron flux increases or decreases.


What does reactor mean?

A reactor is a device that is designed to contain and control nuclear reactions, producing heat that can be converted into electricity. Reactors are used in nuclear power plants for generating electricity and in research facilities for various scientific purposes.


Where is the nearest nuclear power station to Sunderland?

If you mean Sunderland in the UK, this is Hartlepool, a twin reactor AGR plant


What is the examples of energy produce nuclear reactor?

If you mean energy produced by nuclear reactors, then "heat" and "light" would be the answers (Just think of the sun)


What does a reactor consists of?

This question is too wide to be answered. If you mean a nuclear reactor, say so in the question. If you mean a chemical reaction vessel, say so and indicate what kind of reaction. If you mean something else, tell us what. Please submit a new question.


What do you mean by nuclear accidents and can you explain two basic types of nuclear weapons?

A nuclear accident is the unintended release of nuclear radiation into the environment, such as damage to a nuclear reactor or to a nuclear weapon (plane crash carrying nuclear bombs, etc). The two basic forms of nuclear weapons are fission and fusion weapons.


What bathes the control rods and fuel bundles of the nuclear reactor?

Cooling water bathes the control rods and fuel bundles of a nuclear reactor to remove excess heat generated during fission. It helps regulate the temperature within the reactor core, preventing overheating and ensuring safe operation.


What does pila mean in english?

It means, "pile." It could mean a pile of wool, a pile driven into the ground, a Voltaic pile (battery), or an atomic pile (nuclear reactor).


What is a nuclear reaction coolant?

Presumably you mean nuclear reactor coolant? This is the fluid that transfers the reactor thermal output to the steam raising units in a PWR, or to the turbine in a BWR, in which cases it is natural water. Gas cooled reactors can use carbon dioxide or helium, and CANDU reactors use heavy water.


What is the start up time for nuclear?

The start-up time for nuclear reactors can vary depending on the type and size of the reactor. Generally, it can take several hours to several days for a nuclear reactor to start up and reach full power operation. The process involves gradually increasing power levels while ensuring safety and stability.
