Abstract

The invention belongs to the field of nuclear power plant operation technology and particularly relates to a containment bulge test parameter collection device and a collection method thereof. The device comprises a displayer A, a keyboard A, a collection cabinet A, a middle wiring cabinet, a displayer B, a keyboard B and a collection cabinet B. The collection method of the containment bulge testparameter collection device comprises the steps that first, connection with the containment bulge test parameter collection device is established; second, data in the collection cabinet A (6) is collected; and third, data in the collection cabinet B (13) is collected. The designed containment bulge test parameter collection device is successfully applied to a containment overall sealing test of four nuclear power units in a certain nuclear power plant, and through actual operation, the device fully shows the advantages of high system accuracy and reliable design.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant operation, and in particular relates to a containment pressure test parameter collection device and a collection method thereof. Background technique [0002] At present, a monitoring system for the overall sealing test parameters of a nuclear power unit’s containment is designed and supplied abroad. The system is used to collect the pressure, temperature and humidity parameters in the containment under pressure conditions, and the dry air quality leakage is calculated by the gas state equation, so as to obtain The leakage rate of the containment is calculated to verify its tightness. The pre-commissioning and first in-service containment integrity tests of the overall containment were carried out through this system. During the test using the original system, the following problems existed: the original acquisition system did not use redundant technology in design, such as power outa...
