Method for automatically producing high-temperature nuclear energy for long term under any power

Abstract

The invention discloses a method for automatically producing nuclear energy for long term under any power. The method comprises the following steps of: in a high-boiling point heating medium deep-tank type reactor which runs under the normal pressure, generating a natural cycle with a temperature difference of a high-boiling point heating medium between an ascending flow passage and a descending flow passage in the deep-tank type reactor; making the high-boiling point heating medium transversely flow by an annular pebble bed reactor in the high-boiling point heating medium deep-tank type reactor with the natural cycle; making the high-boiling point heating medium pass through an open heat exchanger in the heating medium deep-tank reactor with the natural cycle; totally transferring fission produced by the reactor to a secondary high-boiling point heating medium; not arranging control-compensation rod bundles in the high-boiling point heating medium deep-tank type reactor; under the function of a negative temperature coefficient of the reactor per se and along with demands on external loads, ending a life cycle of the reactor from the starting to running of the reactor; and during the long-time natural cycle, making the secondary high-boiling point heating medium enter an energy-utilization factory through a group of double-protection valves so as to directly utilize high-temperature heat energy or generate electricity.

Description

Technical field [0001] The present invention proposes a method that can automatically operate for a long time under any power to produce high-temperature nuclear energy. Unlike most current commercial nuclear power plants or advanced reactor types in research, this method has real inherent safety characteristics, and can be free from the size limit of the reactor power. Under the super power that exceeds the current largest commercial nuclear power plant many times, it does not require special personnel to operate long-term automatic operation , Thus greatly simplifying systems and equipment, streamlining operation and maintenance personnel, reducing investment and operating costs; it can also cover a broader nuclear energy application market: such as hydrogen production from water, coal to oil, thorium utilization, accelerated nuclear fuel conversion and proliferation, Sea water desalination, etc., while drastically reducing greenhouse gas emissions. The site conditions of the...

Problems solved by technology

[0025] Since this patent is the first patent for an inherently safe nuclear energy production method in the world, it has not yet fully studied how to utilize its huge potential, and failed to break through the world-class difficult technical key that makes the construction and power generation costs of nuclear power lower than ordinary coal-fired power plants. Therefore, it is impossible to completely rely on market competition and not rely on national policy preferences (such as carbon emission tax), so that nuclear energy can replace coal-fired power stations as the main force of energy supply.
