Problems solved by technology

The actual calculation of the free volume requires on-site survey of the size of all factors that affect the free volume within the boundary of the main control room, and then calculates the initial free volume through computer three-dimensional simulation, and then calculates the next free volume iteratively through the endoleakage test data, and so on. Get closer to the actual free volume, long test period and large engineering volume

Embodiment Construction

[0039] Below in conjunction with accompanying drawing, the embodiment of the preparation method of a kind of detection sample of the present invention is introduced:

[0040] Such as figure 1 As shown, the invention provides a method for measuring the free volume of a room of arbitrary shape, comprising:

[0041] S100 measures the gas quality of the preset volume in the room to be tested;

[0042] S200 Add tracer gas into the room to be tested;

[0043] S300 measures the gas mass in the room to be tested after adding the tracer gas, which is the same as the above preset volume;

[0044] S400 Calculate the free volume of the room to be tested according to the added tracer gas mass, the gas mass difference between the two measurements and the preset volume.

[0045] Wherein, said measuring the gas quality of the preset volume in the room to be tested comprises:

[0046] Diffuse other substances in the room to be tested into a container with a preset volume;

[0047] Measure...

Abstract

The invention discloses a method and system for measuring the free volume of a room of any shape. The method comprises steps that the mass of gas of a preset volume in a to-be-measured room is measured; tracer gas is added into the to-be-detected room; the mass of the gas with the same volume as the preset volume in the to-be-measured room is measured after the tracer gas is added; and the free volume of the to-be-measured room is calculated. The system comprises a first measurement unit for measuring the mass of a gas of a preset volume; a tracing unit which is used for adding tracing gas; asecond measuring unit which is used for measuring the gas mass of a preset volume; and a calculation unit which is used for calculating the free volume of the to-be-measured room. The system is advantaged in that the tracer gas method is adopted, the volume of the free volume is measured through the change of the injected mass volume of the tracer gas, the test period of original iterative computation is greatly shortened, the measurement workload of the volume of sundries in the free volume in iterative computation is reduced, and measurement precision of the free volume is improved.

Description

technical field [0001] The invention belongs to the field of nuclear power, and in particular relates to a method and system for measuring the free volume of a room with any shape. Background technique [0002] The free volume refers to the sum of the volumes that the gas can reach the room, and the free volume is closely related to the air exchange rate of the room. , Anti-biochemical attacks, etc.); Ultra-precision manufacturing, biopharmaceutical and other production workshops have important application value in the fields of cleanliness control and maintenance. [0003] The main control room of the nuclear power plant is the nerve center and control center of the nuclear power plant, which is of decisive significance to the safe operation of the nuclear power plant. After an accident in a nuclear power plant (for example: LOCA, DBA such as bombing rods, serious accidents such as core melting, biochemical attack, etc.), the main control room area must provide the necessa...
