After the coolant leaves the discharge side of the pump, it will enter the cold leg and continue to the reactor. The coolant will then pass through the nuclear core and through the fuel, where it collects heat and is sent back to the steam generators. The main components of a reactor coolant pump. Electric motor.

Feb 11, 2014 · The PHWRs can be refueled while at full power, which makes them very efficient in their use of uranium (it allows for precise flux control in the core). The PHWRs use a natural uranium as fuel (in the form of ceramic UO2).

An adiabatic process is a thermodynamic process in which there is no heat transfer into or out of the system (Q = 0). The system can be considered to be perfectly insulated.In an adiabatic process, energy is transferred only as work. The assumption of no heat transfer is very important since we can use the adiabatic approximation only in very rapid processes.

The bremsstrahlung is electromagnetic radiation produced by the acceleration or deceleration of a charged particle when deflected by magnetic fields (an electron by a magnetic field of particle accelerator ...

Atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force, while protons repel each other via the electric force due to their positive charge. These two forces compete, leading to various stability of nuclei.

In the physics of nuclear decays, a radioactive equilibrium exists when a radioactive nuclide is decaying at the same rate it is being produced. The disintegrating nucleus is usually referred to as the parent nucleus, and the nucleus remains as the daughter nucleus after the event.

Nov 21, 2014 · In conjunction with the neutron flux, it enables the calculation of the reaction rate, for example to derive the thermal power of a nuclear power plant. The standard unit for measuring the microscopic cross-section (σ-sigma) is the barn , which is equal to 10 -28 m 2 .

Internal conversion is an electromagnetic process by which an excited nuclear state decays by the direct emission of one of its atomic electrons.

Although water is a low-density material and low Z material, it is commonly used in nuclear power plants because these disadvantages can be compensated with increased thickness. Half Value Layer of Water . The half-value layer expresses the thickness of absorbing material needed to reduce the incident radiation intensity by a factor of two.

Thermal neutrons rely on nuclear reactions such as the (n,γ) or (n,α) reactions to produce ionization. Materials such as LiI(Eu) or glass silicates are therefore particularly well-suited for detecting thermal neutrons.
