Description

Method and device for automatically identifying static seal overhaul skill level of nuclear power plant Technical Field The invention belongs to the technical field of nuclear power plant training and authorization, and particularly relates to a method and a device for automatically identifying the static seal overhaul skill level of a nuclear power plant. Background The partial radioactive boundary seal of the nuclear power plant is composed of a flange, threads and a sealing pair. The quality of the repair (installation/assembly/maintenance) of the components is critical to the operation of the nuclear power plant. Its service (installation/assembly/maintenance) speed and safety, quality, while also implying high performance. The quality of its service (installation/assembly/maintenance) is determined by the skill level of the plant installer. Currently, static seal service levels of nuclear power plant service (installation/assembly/maintenance) personnel (especially high-fluidity contractors) are uneven, and the service capability level of the static seal is difficult to quantitatively evaluate. Meanwhile, the static seal overhaul capacity of a large number of overhaulers is checked with time and labor (commentary), and the problem of non-uniform evaluation standard scale exists. Disclosure of Invention The invention aims to provide a method and a device for automatically identifying the static seal overhaul skill level of a nuclear power plant, which can solve the problems that the static seal overhaul skill level is difficult to quantitatively evaluate, the standard scale of the assessment is not uniform, and the assessment consumes time and much labor.
