Consumption of a ~1000MWe reactor.

Annual enriched uranium consumption of this reactor is about 25 tonnes of enriched uranium.

Annual matter consumption of this reactor is about 1.051 kg.

NPP - Lesson 1

A nuclear power plant (nuclear power station) looks like a standard thermal power station with one exception. The heat source in the nuclear power plant is a nuclear reactor. As is typical in all conventional thermal power stations the heat is used to generate steam which drives a steam turbine connected to a generator which produces electricity.

As you can see the nuclear power plant consist of two main buildings:

- Containment building (houses Nuclear Reactor)
- Turbine building (houses Turbo Generator)

Nuclear Fission - Lesson 1

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a large amount of energy. In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process. The case of decay process is called spontaneous fission and it is very rare process.

The temperature in the centerline of a fuel pellet may reach, for example, about 1200°C under normal conditions. This strongly depends on many variables such as: linear heat rate, pellet-cladding gap, pellet thickness etc.

The body of the reactor vessel is constructed of a high-quality low-alloy carbon steel, and all surfaces that come into contact with reactor coolant are clad with a minimum of about 3 to 10 mm of austenitic stainless steel in order to minimize corrosion.

Operating with a negative MTC is favorable operational characteristics. To a certain extent the reactor is self-regulating and the reactor power may be controlled via the steam turbine and via grid requirements.

In other words, a reactor can follow changes in turbine load and can adjust its thermal power without any operator intervention.

Is an atom an empty space?

The volume of an atom is about 15 orders of magnitude larger than the volume of a nucleus. It may seem, that the space and in fact the matter is empty, but it is not.

Antimatter is more common, than it may seem.

For example, the human body is also a source of antimatter. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. Traces of 40K are found in all potassium, and it is the most common radioisotope in the human body.

About 89.28% of the time (10.72% is by electron capture), it decays to calcium-40 (40Ca) with emission of a beta particle (β−, an electron) with a maximum energy of 1.33 MeV and an antineutrino, which is an antiparticle to the neutrino.

Very rarely (0.001% of the time) it will decay to 40Ar by emitting a positron (β+) and a neutrino.

The rest mass an atomic nucleus is measurably smaller than the sum of the rest masses of its constituent protons, neutrons and electrons.

The reactor pressure vessel is the key component, which limits the thermal efficiency of each nuclear power plant (LWR), since it limits maximum achievable boiler pressure.
