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

Abstract

The invention discloses a method for automatically producing high-temperature 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 high-boiling point heating medium deep-tank type reactor; making the high-boiling point heating medium transversely flow by an ultra-low-resistance 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 ultra-low-resistance open heat exchanger in the high-boiling point 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 a plurality of 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 when the reactor is automatically run for long, making the secondary high-boiling point heating medium enter an energy-utilization factory through a group of overpressure double-protection valves so as to directly utilize high-temperature heat energy or generate electricity.

Description

technical field The invention proposes a method for producing high-temperature nuclear energy that can operate automatically for a long time at any power. Unlike most current commercial nuclear power plants or advanced reactor types in research, this method has real inherent safety characteristics, and can not be limited by the power of the reactor. Under the ultra-high power many times higher than the current largest commercial nuclear power plant, it does not require special personnel to operate for a long time automatically , thus greatly simplifying the system and equipment, streamlining operation and maintenance personnel, reducing investment and operating costs; it can also cover a wider nuclear energy application market: such as hydrogen production from water, oil from coal, utilization of thorium, acceleration of nuclear fuel conversion and multiplication, Seawater desalination, etc., while significantly reducing greenhouse gas emissions. The site conditions of the hig...
