Smirnov Nuclear Fusion Institute, RRC ’Kurchatov Institute’, Moscow, Russia Received 8 June 2009, accepted for publication 26 November 2009 Published 30 December 2009 Online at stacks.iop.org/NF/50/014003 In the USSR, nuclear fusion research began in 1950 with the work of I.E. Tamm, A.D. Sakharov and colleagues. They formulated the principles of magnetic confinement of high temperature plasmas, that would allow the development of a thermonuclear reactor. Following this, experimental research on plasma initiation and heating in toroidal systems began in 1951 at the Kurchatov Institute. From the very first devices with vessels made of glass, porcelain or metal with insulating inserts, work progressed to the operation of the first tokamak, T-1, in 1958. More machines followed and the first international collaboration in nuclear fusion, on the T-3 tokamak, established the tokamak as a promising option for magnetic confinement. Experiments continued and specialized machines were developed to test separately improvements to the tokamak concept needed for the production of energy. At the same time, research into plasma physics and tokamak theory was being undertaken which provides the basis for modern theoretical work. Since then, the tokamak concept has been refined by a world-wide effort and today we look forward to the successful operation of ITER.

Chapter 2 Design and Operation of a Pressurised Water Reactor
Chapter 2 Design and Operation of a Pressurised Water Reactor 2.1. General information about reactor operation The nuclei of some isotopes contained in nuclear fuel, such as 235U and 239Pu, can split up (fission) into two1 smaller fragments called “fission products”. These fragments have large amounts of kinetic energy that is mainly released as kinetic thermal energy in the surrounding fuel material. This release of energy is used to generate electricity in power reactors. Fission into two fragments can either be induced by neutrons (induced fission) or occur spontaneously in the case of heavy isotopes (spontaneous fission). Fission is accompanied by the release of two to three neutrons. Some of these neutrons may in turn initiate other fissions (the principle behind a nuclear chain reaction), be absorbed into the fuel without initiating any nuclear fission, or escape from the fuel. Neutrons produced by fission from the neutrons of one generation form the neu- trons of the next generation. The effective neutron multiplication factor, k, is the aver- age number of neutrons from one fission that cause another fission. The value of k determines how a nuclear chain reaction proceeds: – where k < 1, the system is said to be “subcritical”. The system cannot sustain a chain reaction and ends up dying out; 1. In about 0.4%-0.6% of cases the fission can be into three fission products, this is termed “ternary fission”. 12 Nuclear Power Reactor Core Melt Accidents – where k = 1, the system is “critical”, i.e., as many neutrons are generated as are lost. The reaction is just maintained. -

History of Radiation and Nuclear Disasters in the Former USSR
History of radiation and nuclear disasters in the former USSR M.V.Malko Institute of Power Engineering National Academy of Sciences of Belarus Akademicheskaya Str.15, Minsk, 220 000, Republic of Belarus E-mail: [email protected] Abstracts. The report describes the history of radiation and nuclear accidents in the former USSR. These accidents accompanied development of military and civilian use of nuclear energy. Some of them as testing of the first Soviet nuclear, Kyshtym radiation accident, radiation contamination of the Karachai lake and the Techa river, nuclear accidents at the Soviet submarine on August 10, 1985 in the Chazhma Bay (near Vladivostok) as well as nuclear accidents on April 26, 1986 at the Chernobyl NPP were of large scale causing significant radiological problems for many hundreds thousands of people. There were a number of important reasons of these and other accidents. The most important among them were time pressure by development of nuclear weapon, an absence of required financial and material means for adequate management of problems of nuclear and radiation safety, and inadequate understanding of harmful interaction of ionizing radiation on organism as well as a hypersecrecy by realization of projects of military and civilian use of nuclear energy in the former USSR. Introduction. The first nuclear reactor in the USSR reached the critical state on the 25 December 1946 [1] or 4 years later than reactor constructed by Enrico Fermi [2]. The first Soviet reactor was developed at the Laboratory N2 in Moscow (later I.V.Kurchatov Institute of Atomic Energy). This was a very important step in a realization of the Soviet military atomic program that began in September 1942. -

Looking Back at Half a Century of Fusion Research P. STOTT Association Euratom-CEA, Centre de Cadarache, 13108 Saint Paul lez Durance, France. This article gives a short overview of the origins of nuclear fusion and of its development as a potential source of terrestrial energy. 1 Introduction A hundred years ago, at the dawn of the twentieth century, physicists did not understand the source of the Sun‘s energy. Although classical physics had made major advances during the nineteenth century and many people thought that there was little of the physical sciences left to be discovered, they could not explain how the Sun could continue to radiate energy, apparently indefinitely. The law of energy conservation required that there must be an internal energy source equal to that radiated from the Sun‘s surface but the only substantial sources of energy known at that time were wood or coal. The mass of the Sun and the rate at which it radiated energy were known and it was easy to show that if the Sun had started off as a solid lump of coal it would have burnt out in a few thousand years. It was clear that this was much too shortœœthe Sun had to be older than the Earth and, although there was much controversy about the age of the Earth, it was clear that it had to be older than a few thousand years. The realization that the source of energy in the Sun and stars is due to nuclear fusion followed three main steps in the development of science. -

UDC 621.039 The Monte Carlo Estimation of the Effect of Uncertainties in the Input Data for the Transport Equation Solving by the MCU Code D.S. Oleynik NRC “Kurchatov Institute”, 1, Kurchatov Sq., Moscow, 123182 Direct taking into account the initial data uncertainty is realized in the new version of tally module of the MCU code. This approach is recommended by international standard “A Guide to Expression of Uncertainty in Measurement” (ISO 13005). The new module allows calculating the effect of uncertainties in input quantities for neutron characteristics of core. These uncertainties are usually caused by technological tolerances. Devel- oped code is adapted to parallel computing that drastically decreases calculation time. Testing is performed by means of a simplified model of the Godiva bare-sphere critical experiment and infinite lattices of vari- ous fuel assemblies (VVER-440, VVER-1000 and VVER-1200). The results of calculation is com- pared with published MCNP5 ones (for Godiva experiment) and with RADAR engineering code ones. -

Pressurized Water Reactor (PWR) Systems
Reactor Concepts Manual Pressurized Water Reactor Systems Pressurized Water Reactor (PWR) Systems For a nuclear power plant to perform the function of generating electricity, many different systems must perform their functions. These functions may range from the monitoring of a plant parameter to the controlling of the main turbine or the reactor. This chapter will discuss the purposes of some of the major systems and components associated with a pressurized water reactor.

WATER PUMP CONTAINMENT AUXILIARY BUILDING SUMP TURBINE BUILDING There are two major systems utilized to convert the heat generated in the fuel into electrical power for industrial and residential use. The primary system transfers the heat from the fuel to the steam generator, where the secondary system begins. The steam formed in the steam generator is transferred by the secondary system to the main turbine generator, where it is converted into electricity. After passing through the low pressure turbine, the steam is routed to the main condenser. Cool water, flowing through the tubes in the condenser, removes excess heat from the steam, which allows the steam to condense. The water is then pumped back to the steam generator for reuse. In order for the primary and secondary systems to perform their functions, there are approximately one hundred support systems. -
