Technical Field

[0001] This invention belongs to the field of nuclear power plant training and licensing technology, specifically relating to a method and apparatus for assessing the skill level of static sealing maintenance in automated nuclear power plants. Background Technology

[0002] The radioactive boundary seals of a nuclear power plant are composed of flanges, threads, and sealing pairs. The quality of component maintenance (installation / assembly / repair) is crucial to the operation of the nuclear power plant. Its speed, safety, and quality imply high performance. The quality of maintenance (installation / assembly / repair) is determined by the skill level of the nuclear power plant's installation personnel.

[0003] Currently, the static sealing maintenance skills of nuclear power plant maintenance (installation / assembly / repair) personnel (especially highly mobile contractors) vary widely, making it difficult to quantify their static sealing maintenance capabilities. Furthermore, assessing the static sealing maintenance capabilities of a large number of maintenance personnel is time-consuming, requires significant manpower (evaluators), and suffers from inconsistent evaluation standards. Summary of the Invention

[0004] The purpose of this invention is to provide a method and apparatus for assessing the skill level of static sealing maintenance in automated nuclear power plants, which can overcome the problems of difficulty in quantifying and evaluating the skill level of static sealing maintenance, inconsistent assessment standards, and the high time and manpower required for assessment.

[0005] The technical solution of the present invention is as follows: A method for assessing the skill level of static sealing maintenance in automated nuclear power plants, comprising the following steps:

[0006] Step 1: The assessors collect basic information about the personnel through the host computer and system;

[0007] Step 2: The host computer and system execute database assessment items matching to determine the assessment specialties and content;

[0008] Step 3: The examiners use the host computer and system to select and confirm the questions, randomly selecting and confirming the examination questions.

[0009] Step 4: The host computer and system read the preset system and equipment status, and control the solenoid valve and proportional valve through the cable to set the pressure status in the system, thus completing the automatic setting of the initial state of the equipment.

[0010] Step 5: Based on the questions, the examiners complete the skills assessment operations on the flange device, threaded device, and sealing pair device, and the system confirms the completion.

[0011] Step 6: The host computer and system read the preset system and equipment status, control the solenoid valve and proportional valve through cables to set the pressure status in the system, and read the results of the mass flow meter;

[0012] Step 7: Verify and evaluate the system assessment results, and the assessment ends.

[0013] The first step involves the assessment personnel completing basic information collection by using facial recognition or manually entering information such as employee number and ID card number.

[0014] An apparatus for assessing the skill level of automated nuclear power plant static sealing maintenance includes solenoid valves, pipelines, flange devices, threaded devices, sealing pairs, proportional valves, cables, a host computer and system, a pressure source and booster pump, and a mass flow meter. The solenoid valves are connected to the flange devices, threaded devices, sealing pairs, and mass flow meters respectively. The mass flow meters are connected to the host computer and system, the mass flow meters are connected to the proportional valves, the proportional valves are connected to the host computer and system, the proportional valves are also connected to the pressure source and booster pump, and the solenoid valves are connected to the host computer and system.

[0015] The solenoid valve is connected to a flange device, a threaded device, a sealing pair device, and a mass flow meter via pipelines.

[0024] like Figure 1 As shown, this invention provides a method for assessing the skill level of static sealing maintenance in automated nuclear power plants, comprising:

[0025] Step 1: The assessors use the host computer and system 208 to collect basic information about the personnel 101. The assessors complete the basic information collection by using facial recognition or manually entering information such as employee number and ID card number.

[0026] Step 2: The host computer and system 208 automatically execute database assessment item matching 102 to determine the assessment specialty and content;

[0027] Step 3: The examiners use the host computer and system 208 to execute question selection and confirmation 103, randomly select and confirm the examination questions;

[0028] Step 4: The host computer and system 208 read the preset system and equipment status in the program, and control the solenoid valve 201 and proportional valve 206 through the cable 207 to set the pressure status in the system, thus completing the automatic setting of the initial state of the equipment 104.

[0029] Step 5: The examiners complete the skills assessment operations on flange device 203, thread device 204, and sealing pair device 205 according to the questions, and the system confirms that 105 is completed.

[0030] Step 6: The host computer and system 208 read the preset system and equipment status in the program, control the solenoid valve 201 and proportional valve 206 through cable 207 to set the pressure status in the system, and read the result of mass flow meter 210.

[0031] Step 7: The system automatically verifies and evaluates the assessment results (106). The assessment ends.

[0032] like Figure 2As shown, an apparatus for assessing the skill level of static sealing maintenance in automated nuclear power plants includes a solenoid valve 201, a pipeline 202, a flange device 203, a threaded device 204, a sealing pair device 205, a proportional valve 206, a cable 207, a host computer and system 208, a pressure source and booster pump 209, and a mass flow meter 210. The solenoid valve 201 is connected to the flange device 203, the threaded device 204, the sealing pair device 205, and the mass flow meter 210 via the pipeline 202. The mass flow meter 210 is connected to the host computer and system 208 via the cable 207.

The proportional valve 206 is also connected to the pressure source and booster pump 209. The solenoid valve 201 is connected to the host computer and system 208 via the cable 207.

[0033] In the static sealing maintenance skill level assessment of nuclear power plant personnel, after information collection (101) is conducted, their specialty and assessment content are determined according to the database assessment items (102). Then, assessment questions are randomly selected from the database based on their specialty and assessment content (103). After the personnel confirm the questions, the host computer and system (208) read the preset system and equipment status in the program, and control the solenoid valve (201) and proportional valve (206) through cable (207) to set the pressure state within the system, completing the automatic initial state setting of the equipment (104). According to the questions, the personnel complete the skill assessment operation on the flange device (203), threaded device (204), and sealing pair device (205), and the system confirms the completion (105). The host computer and system (208) read the preset system and equipment status in the program, control the solenoid valve (201) and proportional valve (206) through cable (207) to set the pressure state within the system, read the results from the mass flow meter (210), and complete the system assessment result verification and evaluation (106).

[0035] When nuclear power plant personnel conduct static sealing maintenance skill level assessments, after collecting basic personnel information (101), their specialties and assessment content are determined based on database assessment item matching (102). Then, assessment questions are randomly selected and confirmed from the database based on their specialties and assessment content (103). After the personnel confirm the questions, the host computer and system (208) read the preset system and equipment status in the program, and control the solenoid valve (201) and proportional valve (206) through cable (207) to set the pressure status within the system, completing the automatic initial state setting of the equipment (104). According to the questions, the personnel complete the skill assessment operation on the flange device (203), threaded device (204), and sealing pair device (205), and the system confirms the completion (105). The host computer and system (208) read the preset system and equipment status in the program, control the solenoid valve (201) and proportional valve (206) through cable (207) to set the pressure status within the system, read the results from the mass flow meter (210), and complete the system assessment result verification and evaluation (106).
