Nuclear power units with a VVER-1200 type reactor, floating nye power plants (FNPPs) are evolutionary projects. This means that they use proven, time-tested change decisions; they are similar to their predecessors. VVER-1200 “Evolved” from the VVER-1000 reactor, and the prototype for the FNPP served as reactors installed on icebreakers. In the same time there are promising types of nuclear power …
Most nuclear power plants – both in Russia and abroad – operate in bottom reactors in which the thermal energy of a nuclear fission reaction transferred to water. Other countries also have nuclear power units, where the coolant is heavy water (D 2 O) or carbon dioxide. But it is in our country that a technology has been implemented …
So, it turned out that the channel uranium-graphite reactor is not suitable for use on submarines and surface ships. And with pressurized water reactor, the situation is exactly the opposite: being originally created for ships, it is still active It is also actively operated on land. In accordance with the new goals, the reactor has become …
Let us mention one more promising application of techno logical principles used in the design of ships with nuclear reactor. Let’s say there is a settlement or an industrial an enterprise located in an underdeveloped region of the country – example, in Chukotka or Yakutia. Providing heat and energy zheniya is a long-standing problem in those areas, …
The RBMK-1000 reactor is a good option, but not the only one ny. When the United States launched the world’s first nuclear power plant in 1954 submarine, in our country, intensive work was carried out on creation of its own nuclear submarine (Project 627). The main con- V.N.Peregudov was appointed the constructor of the first nuclear submarine, …

Rum RBMK The world’s first nuclear power plant used a uranium-graphite reactor AM-1 , – similar in design to the above-mentioned PUGR. AM-1 became the world’s first power reactor, i.e. reactor, chief whose purpose is to generate electricity. As fuel for it was also used uranium, or rather, uranium dioxide UO 2 enriched in the isotope 235 U. The moderator, as in the PUGR, was …
management and protection The main tool for the control and management of nuclear reactions it is the control and protection system (CPS). Principle of operation The CPS is as follows: to prevent the very rapid multiplication of neutro- nov, leading to a nuclear explosion, materials are introduced into the core, absorbing neutrons (so-called “absorbers”). One of the most …
Before considering the device and principle of operation of nuclear power plants, let’s dwell in more detail on the device the core – the part of the reactor that contains the nuclear fuel fuel and a controlled fission chain reaction proceeds. Nuclear fuel, which is in most cases di- uranium oxide (UO 2 ) enriched in the …
In Chapter 1 “Scientific Foundations of Nuclear Power” we talked about that, using materials that absorb neutrons, you can to create a controlled fission chain reaction. Fast neutrons, formed during the fission of uranium nuclei, it is required to slow down – for this It is necessary to use a retarder. As a moderator, Graphite, water (H 2 O), …
The nuclear fuel production division is a Corporation TVEL, the main enterprises of which are OJSC Mashi- no-building plant “(Elektrostal, Moscow region) and OJSC “Novosibirsk plant of chemical concentrates” (Novosibirsk, Novosibirsk- sky region). Uranium dioxide powder for tablet pressing are used in the same factories. Zirconium for the manufacture of fuel rods haunted at JSC “Chepetsk Mechanical …
