Nuclear decay occurs when the nucleus of an atom is unstable and spontaneously emits energy in the form of radiation. The result is that the nucleus changes into the nucleus of one or more other elements.

Heat is removed during normal power operation by generating steam in the reactor vessel and then using that steam to generate electrical energy. When the reactor is shutdown, the core will still continue to generate decay heat.

The heat produced by the decay of radioactive fission products after a reactor has been shut down.

Decay heat is the heat released as a result of radioactive decay. This heat is produced as an effect of radiation on materials: the energy of the alpha, beta or gamma radiation is converted into the thermal movement of atoms.

The equation for half-life is T 1 / 2 = l n ( 2 ) λ , where T 1 / 2 is the half-life, and λ is the decay constant, which is a value specific to each chemical.

Suppose N is the size of a population of radioactive atoms at a given time t, and dN is the amount by which the population decreases in time dt; then the rate of change is given by the equation dN/dt = −λN, where λ is the decay constant.

Heating from the decay of radioactive nuclides in shutdown reactors plays an important role in the safety evaluation of nuclear power plants. It also must be known in order to design spent fuel storage systems, shutdown reactor cooling systems and heat sink, reprocessing and nuclear waste disposal systems.

As physics would have it, the decay heat power level is usually about 6-7% of the full power of the reactor immediately after a shutdown. Then it decays exponentially such that it's below 1% within a day and continues to drop.

As physics would have it, the decay heat power level is usually about 6-7% of the full power of the reactor immediately after a shutdown. Then it decays exponentially such that it's below 1% within a day and continues to drop.

The decay heat is obtained by summing over the beta and gamma energies of each radioactive nuclide. The input nuclear data consists of fission yields, half- lives, branching ratios, and average energies of beta particles and gamma rays.
