How to write a nuclear power essay
The main goal of the nuclear energy is to provide a demonstration of a new generation of nuclear reactors based on the use of the reaction of reactants produced in the reactor. The reactor is designed to kill hydrogen in a closed cycle of a reactor.
The main engineering problem faced by researchers working in this field is the creation of an efficient impulse driver aimed to accelerate the shell. The required power can be obtained with the use lasers (which is done in modern experimental installations). But the efficiency of lasers is too small to count on a positive energy release.
Currently, other drivers for inertial synthesis are being developed. Most of them are based on the use of ion and electron beams, the creation of X-rays using Z-pinches. Scientists in the United States have been working on the construction of National Ignition Facility designed to produce an ignition.
Another direction in controlled thermonuclear fusion which may be described in alternative energy sources research paper is reactors based on magnetic confinement. The magnetic field is used to isolate the hot deuterium-tritium plasma from contact with the inner surface of the capsule. Unlike inertial reactors, magnetic fusion reactors are stationary devices with relatively low volumetric energy release and large dimensions.
During 40 years of thermonuclear research, various systems for magnetic confinement have been proposed, among which the tokamak occupies a leading position. Another system for magnetic confinement of plasma is a stellarator. Large stellarators are currently being built in Japan and Germany.
In a tokamak, the hot plasma has the form of a torus and is kept in place by means of a magnetic field generated both by external magnetic coils and by current flowing through the plasma itself. However, the instabilities limit the allowable plasma pressure at a level of several percent of the magnetic pressure, and, therefore, the magnetic field is several times higher than the level required for the equilibrium of the plasma.
To avoid the high energy consumption for maintaining the magnetic field, it must be created in the reactor by superconducting magnets. Such a technology is already at our disposal. One of the largest experimental tokamaks T-15 uses superconducting magnets to create magnetic fields.
The tokamak can operate in the regime of successive micro explosions at a frequency of several hertz, and the energy released in the chamber will be removed by the coolant and used to generate electricity.
Over the years, great progress has been made in understanding the physical processes of the target occurring during its compression and the interaction with the surrounding environment. Moreover, modern multilayer targets have already been checked with the help of underground nuclear explosions which make it possible to provide the required power of radiation. Ignition and large positive release were obtained. Therefore, it may be stated in renewable energy sources essay that there is no doubt that this method can lead to success.
The main technical problem faced by researchers working in this field is the creation of an efficient impulse driver aimed to accelerate the shell. The required power can be obtained with the use lasers (which is done in modern experimental installations). But the efficiency of lasers is too small to count on a positive energy release.
The tokamak can operate in the regime of starting, steady plasma heating has been created. Heat is collected and released in the chamber.
