Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, a method for on-line tritium measurement based on sequential measurement dynamic error calculation method can effectively avoid the time waste caused by fixed time measurement and effectively control the measurement period in the shortest time, specifically including the following steps:

[0021] Step 1: Select sampling loops sequentially from the first sampling loop;

[0022] Step 2: Measure the selected sampling loop through the ionization chamber for 40 seconds as the response time of the ionization chamber;

[0023] Step 3: The ionization chamber continuously outputs the measurement signal (ie, the concentration of tritium) for the sampling loop, and the data analysis module is set to connect with the ionization chamber. The data analysis module receives the measurement signal output by the ionization chamber, an...

Abstract

The invention belongs to the technical field of nuclear power plant tritium concentration measurement, particularly relates to an on-line tritium measurement method based on an in-order measurement dynamic error calculation method, which aims to solve the problem of inaccurate measurement caused by change of tritium concentration on site and save the total period time of in-order measurement. According to the dynamic error calculation method for sequential measurement, the problem of inaccurate measurement caused by the change of the tritium concentration on site is solved, meanwhile, the total period time of sequential measurement is scientifically saved, and the measurement accuracy in the shortest time is ensured.

Description

technical field [0001] The invention belongs to the technical field of tritium concentration measurement in nuclear power plant buildings, and in particular relates to an online tritium measurement method based on a sequential measurement dynamic error calculation method. Background technique [0002] The existing on-line tritium measurement system extracts air to measure the tritium concentration in selected rooms one by one. An area consists of one or more rooms, and an area is used as a sampling circuit, but all use a fixed sampling time period. Since tritium is in the The distribution in the air is uneven and changes in real time. If the measurement time is fixed, the ionization analysis of the ionization chamber may switch to the next sampling loop before the measurement is complete, or the measurement time may be wasted. Contents of the invention [0003] The purpose of the invention is to solve the problem of inaccurate measurement caused by the change of tritium co...
