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 china syndrome mean to a nuclear reactor?
In the most severe reactor accident, the fuel will melt and, due to radioactive decay heat, will continue to be very hot. In fact, it will be hot enough to melt through the bottom of the reactor pressure vessel (several inches of steel), and possibly melt/burn through the concrete floor of the reactor building and get into the soil beneath the building. This is what is referred to as the China syndrome, the idea being that the molten mass of fuel is heading toward China on the other side of the earth as it melts through the vessel, concrete, and then soil and rock below the reactor building.
In math what does hg mean?
hectograms
What does Orthochlorobenzalmalononitrile mean?
It's the chemical name for CS gas (tear gas).
What does a yellow flame mean on a gas boiler?
It means you have too much air intake It means you have too much air intake
What is mean by PBM in mass transfer?
It is the log mean value of the inert B in counterdiffusion usually used to find a flux. P = pA1 + pB1 = pA2 + pB2 thus, pB1 = P - pA1, and pB2 = P - pA2, so: pBM = [pB2 - pB1]/ln(pB2/pB1) = [pA1 - pA2]/ln[(P-pA2)/(P-pA1)] happy engineering :)
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?
The term reactor refers to a structure in which material can be made to undergo a controlled nuclear reaction. They are used widely in industrial plants.
How fast does a nuclear fusion reactor work?
Do you mean how much power does it produce? None are working as yet.
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 bathes the control rods and fuel bundles of the nuclear reactor?
Perhaps you mean the water that acts as moderator and fuel coolant
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 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.
