Abstract

The invention discloses a cooling system. The cooling system comprises a gas storage tank for storing cooling gas, a cooling pipeline allowing measuring devices to be placed, and a cooling pond, wherein the gas storage tank is connected with the cooling pipeline through a first gas path pipeline, the cooling pipeline is connected with the cooling pond through a second gas path pipeline, and the cooling pond is connected with the gas storage tank through a third gas path pipeline; and cooling gas in the gas storage tank returns to the gas storage tank through the cooling pipeline and the cooling pond. The temperature of the measuring devices such as a neutron detector is reduced through a gas cooling technique, so that the working temperature of the neutron detector conforms to requirements, and further the neutron detector can normally work. In addition, in a manner that gas is in closed type circulation, gas depletion is reduced, and the leakage of activated gas with radioactive gas is avoided.

Description

technical field [0001] The present invention relates to a cooling system, in particular to a cooling system for measuring devices such as neutron detectors used in high temperature reactors. Background technique [0002] The reactor nuclear monitoring system is one of the essential systems of the reactor. By monitoring the neutron fluence rate, the reactor power level can be quickly obtained, and the reactor information can be provided to the operator. It is also one of the important tools for reactor physics research. [0003] On September 20, 2002, at the International Symposium on Generation IV Reactors held in Tokyo, Japan, six design concepts of Generation IV reactors were announced. One of the main features of Generation IV is the high outlet temperature, which is generally above 500°C , which brings difficulties to the measurement of neutron fluence rate in the reactor. At present, the operating temperature of highly sensitive commercial gas ionization neutron detect...
