Nuclear power of the future

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 …

Floating nuclear power plant (FNPP)

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, …

Nuclear installations for submarines and icebreakers

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, …

Nuclear power plant with a reactor

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 …

Fission chain reaction control: system

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 …

NUCLEAR POWER ENGINEERING IN RUSSIA

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), …

Current state and prospects Part 2

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 …
