Description

Technical Field

[0001] The present application belongs to the technical field of radiation protection of HPR1000 nuclear power units, and specifically relates to a method and device for evaluating radiation protection of RX plant parallel flaw detection of HPR1000 nuclear power units. Background Art

[0002] During the overhaul of the HPR1000 nuclear power unit, in order to safely and reasonably shorten the overhaul period, improve efficiency, and ensure radiation safety, parallel flaw detection was implemented in the RX plant. The radiation protection assessment method of parallel flaw detection in the RX plant during the overhaul of the HPR1000 nuclear power unit is a shortcoming in the field of radiation protection at home and abroad. In addition, the skills of the flaw detection radiation protection assessors are relatively high. The radiation protection assessment work is currently mainly skill-based risk analysis, which is not conducive to on-site radiation risk control.

[0003] Since the radiation intensity of the radioactive source used in NDT is high, if the parallel NDT area is set up unreasonably, it will cause unplanned radiation accidents. In order to avoid the safety hazards caused by the unreasonable setting of parallel NDT areas, the parallel NDT areas can be accurately and efficiently evaluated under the premise of ensuring radiation safety. Summary of the invention

[0004] In view of this, the present application is committed to providing a method and device for evaluating radiation protection of parallel flaw detection in the RX building of an HPR1000 nuclear power unit. By creating a parallel flaw detection block evaluation mode, innovatively designing space codes, and independently developing evaluation logic, the technical problem of unplanned radiation accidents caused by unreasonable setting of parallel flaw detection areas due to the high radiation intensity of the flaw detection radiation source is solved.

[0005] The first aspect of the present application provides a method for evaluating radiation protection of parallel flaw detection in RX buildings of HPR1000 nuclear power units, and the method comprises:

[0006] Determine the rooms to be inspected in parallel;

[0007] Get the corresponding area and space code of the room to be judged in parallel flaw detection of HPR1000 nuclear power unit RX plant. Each area of ​​HPR1000 nuclear power unit RX plant is represented by space code, which is divided into first segment code, middle segment code and last segment code. The first segment code is used to identify the flaw detection floor; the middle segment code is used to identify the impact of the flaw detection floor area on other floors; the last segment code is used to identify the impact of the flaw detection floor area on the same floor;

[0008] According to the spatial code of the corresponding area of ​​the room to be judged for parallel flaw detection, combined with the judgment logic, the first segment code, the middle segment code and the last segment code are judged step by step to determine whether the corresponding areas of the parallel flaw detection room can be implemented simultaneously. The judgment principle of the middle segment code is: the same middle segment code area can only be inspected serially. The judgment principle of the last segment code is specifically divided into two parts: the English part judgment and the digital part judgment. The judgment principle of the English part of the last segment code is: if the first segment code is the same and the English part has an inclusion relationship, or the first segment code is different and the English part has a completely identical relationship, then the two areas cannot be inspected at the same time. The judgment principle of the digital part of the last segment code is: after the preliminary judgment, the area cannot be inspected in parallel. If the last segment code has a digital part that needs to be reviewed, such as the middle segment code is the same or the English part of the last segment code is the same, and the last segment code is not completely identical, then the two areas can be inspected at the same time.

The first code is used to identify the flaw detection floor; the middle code is used to identify the impact of the flaw detection floor area on other floors; the last code is used to identify the impact of the flaw detection floor area on the same floor;

[0015] The judgment module, based on the spatial code of the corresponding area of ​​the room to be judged for parallel flaw detection, combines the judgment logic to judge the first segment code, the middle segment code and the last segment code step by step to determine whether the corresponding areas of the parallel flaw detection room can be implemented simultaneously. The judgment principle of the middle segment code is: the same middle segment code area can only be inspected serially. The judgment principle of the last segment code is specifically divided into two parts: the English part judgment and the digital part judgment. The judgment principle of the English part of the last segment code is: if the first segment code is the same and the English part has an inclusion relationship, or if the first segment code is different and the English part has a completely identical relationship, then the two areas cannot be inspected at the same time. The judgment principle of the digital part of the last segment code is: after the preliminary judgment, the area cannot be inspected in parallel. If the last segment code has a digital part that needs to be reviewed, such as the middle segment code is the same or the English part of the last segment code is the same, and the last segment code is not completely identical, then the two areas can be inspected at the same time.

[0016] In a specific embodiment of the present application, the determination module is also used to determine that the entire RX building can only be inspected serially when the outer corridor of the RX building is performing inspection.

[0017] The third aspect of the present application provides a computer device, which includes a processor and a memory.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] At least one embodiment of the present application provides a method for evaluating radiation protection of a HPR1000 type nuclear power unit RX plant in parallel flaw detection. The method for evaluating radiation protection of a HPR1000 type nuclear power unit RX plant in parallel flaw detection includes the following steps.

[0032] S1: Determine the room to be inspected in parallel.

[0033] S2: Obtain the corresponding areas of the rooms to be judged in parallel flaw detection in different areas of the RX plant of the HPR1000 nuclear power unit and the corresponding space codes of the areas. Each area of ​​the RX plant of the HPR1000 nuclear power unit is represented by a space code, and the space code is divided into a first code, a middle code and a last code. The first code is used to identify the flaw detection floor; the middle code is used to identify the impact of the flaw detection floor area on other floors; the last code is used to identify the impact of the flaw detection floor area on the same floor;

[0034] S3: According to the spatial code of the corresponding area of ​​the room to be judged for parallel flaw detection, combined with the judgment logic, the first segment code, the middle segment code and the last segment code are judged step by step to determine whether the corresponding areas of the parallel flaw detection room can be implemented simultaneously. The judgment principle of the middle segment code is: the same middle segment code area can only be inspected serially. The judgment principle of the last segment code is specifically divided into two parts: the English part judgment and the digital part judgment. The judgment principle of the English part of the last segment code is: if the first segment code is the same and the English part has a containing and identical relationship, and the first segment code is different and the English part has a completely identical relationship, then the two areas cannot be inspected at the same time. The judgment principle of the digital part of the last segment code is: after the preliminary judgment, the area cannot be inspected in parallel. If the last segment code has a digital part that needs to be reviewed, such as the middle segment code is the same or the English part of the last segment code is the same, and the last segment code is not completely the same, then the two areas can be inspected in parallel.

[0035] It should be noted that when multiple parallel flaw detection analyses are performed, the evaluation areas are combined one by one and evaluated level by level and pair by pair according to the corresponding area space codes.

[0036] According to the technical solution provided in the embodiment of the present application, by creating a parallel flaw detection block evaluation mode, innovatively designing the space code, and independently developing the evaluation logic, the digital application of parallel flaw detection and radiation protection evaluation of the RX plant of the HPR1000 nuclear power unit is realized, and the parallel flaw detection and radiation protection evaluation of the RX plant of the HPR1000 nuclear power unit is completed safely and efficiently, ensuring the safe and efficient implementation of parallel flaw detection in the RX plant of the HPR1000 nuclear power unit, and optimizing the total construction period of overhaul flaw detection.

[0037] In at least one embodiment of the present application, the HPR1000 nuclear power unit RX plant parallel flaw detection radiation protection assessment method also includes S4.

[0038] S4: When flaw detection is performed in the outer corridor of the RX plant, the entire RX plant can only be inspected serially.

[0039] In at least one embodiment of the present application, the determination principle of the last segment code also includes: if a circle appears in the last segment code, the adjacent areas with the same first segment code and all areas corresponding to the adjacent area segment codes cannot be inspected in parallel.

[0040] The HPR1000 nuclear power unit RX plant parallel flaw detection radiation protection evaluation method can be applied to the HPR1000 nuclear power unit. The following is a specific description taking the HPR1000 nuclear power unit as an example.

[0041] According to the actual layout of the RX plant of the HPR1000 nuclear power unit, the adjacent rooms in space are regarded as non-parallel flaw detection areas. At the same time, considering that some equipment in the RX plant is connected to several rooms, the floors of the RX plant are divided into areas. The HPR1000 nuclear power unit RX plant parallel flaw detection radiation protection evaluation atlas is developed. For details, see Figures 2 to 9 .

[0042] in Figure 2 It is divided into 10 areas, namely 1-1.0-O, 1-1.0-A, 1-1.0-B, 1-1.0-C, 1-2.0-A, 1-2.0-AB, 1-2.0-B, 1-2.0-BC, 1-2.0-C and 1-2.0-AC; Figure 3 It is divided into 8 areas, namely 2-1.0-O, 2-1.0-A, 2-1.0-B, 2-1.0-C, 2-3.0-AB, 2-4.0-BC, 2-5.0-AC, and 2-8.0-ALL; Figure 4 It is divided into 8 areas, namely 3-6.0-O, 3-6.0-AB, 3-6.0-BC, 3-6.0-AC, 3-7.0-A, 3-8.0-ALL, 3-9.0-B, and 3-10.0-C; Figure 5 It is divided into 9 areas, namely 4-6.0-O, 4-6.0-AB, 4-6.0-BC, 4-6.0-AC, 4-7.0-A, 4-8.0-ALL, 4-9.0-B, 4-10.0-C1 and 4-10.0-C2; Figure 6 It is divided into 8 areas, including 5-6.0-AB1, 5-6.0-BC2, 5-6.0-AC3, 5-7.0-A, 5-8.0-ALL, 5-9.0-B, 5-10.0-C1, and 5-10.0-C2; Figure 7 It is divided into 8 areas, namely 6-6.0-AB1, 6-6.0-BC2, 6-6.0-AC3, 6-7.0-A, 6-8.0-ALL, 6-9.0-B, 6-10.0-C1 and 6-10.0-C2; Figure 8 It is divided into 7 areas, namely 7-6.0-AB, 7-6.0-BC, 7-6.0-AC, 7-7.0-A, 7-8.0-ALL, 7-9.0-O, and 7-10.0-O; Fig. 9The total number of regions is 8-6.0-AB, 8-6.0-BC, 8-6.0-AC, 8-7.0-A, 8-8.0-ALL, 8-9.0-O, and 8-10.0-O. The statistics are shown in Table 1 below.

[0043] Table 1 HPR1000 nuclear power unit RX plant block space code table.

[0044]

[0045] In order to meet the principle that “adjacent rooms in space cannot be inspected in parallel”, we independently developed the evaluation logic of the above-mentioned space code.

[0046] The judgment principle is converted into a block judgment logic table for parallel flaw detection in the RX plant of the HPR1000 nuclear power unit. See Table 2 below for details. According to the table in Table 2 below, the following can be used to judge step by step: whether the middle code is the same, whether the first code is the same, whether the last code-English is included / the same, whether the last code-numbers are both included, whether the last code-English+numbers are the same, and whether the blocks of the RX plant of the HPR1000 nuclear power unit can be inspected in parallel can be judged step by step.

[0048]

[0049] After summarizing and arranging, the specific steps of the HPR1000 nuclear power unit RX plant parallel flaw detection radiation protection evaluation method are as follows:

[0050] S1: Determine the room to be tested in parallel;

[0051] S2.1: Verify the corresponding area and the space code corresponding to the area in the parallel flaw detection radiation protection assessment atlas belonging to the RX plant of the HPR1000 nuclear power unit;

[0052] S3.1: According to the HPR1000 nuclear power unit RX plant parallel flaw detection block determination logic table, the middle code, first code, last code - English, last code - number, last code - English + number are determined step by step; complete the evaluation of whether each block of the HPR1000 nuclear power unit RX plant can be inspected in parallel.

[0053] In the above embodiment, according to the characteristics of the spatial layout and parallel flaw detection of the RX plant of the HPR1000 nuclear power unit, after sufficient radiation risk analysis and practice, adhering to the concept of block determination of parallel flaw detection of the RX plant, a radiation protection evaluation atlas of parallel flaw detection of the RX plant of the HPR1000 nuclear power unit is developed, and a radiation protection evaluation method of parallel flaw detection of the RX plant of the HPR1000 nuclear power unit is created, and the digital application of the radiation protection evaluation of parallel flaw detection of the RX plant of the HPR1000 nuclear power unit is realized, which makes up for the shortcomings in the field of radiation protection at home and abroad, and provides a reference for the radiation protection evaluation of parallel flaw detection of the RX plant of the HPR1000 nuclear power unit at home and abroad. The embodiment of this application also innovatively designs the space code, combines the independent research and development judgment principle, safely and efficiently completes the radiation protection evaluation of the parallel flaw detection of the RX plant of the HPR1000 nuclear power unit, ensures the safe and efficient implementation of parallel flaw detection of the RX plant of the HPR1000 nuclear power unit, optimizes the total construction period of overhaul flaw detection, and provides favorable guarantees for the high-quality development of the HPR1000 nuclear power unit.

The judgment principle of the middle segment code is: the same middle segment code area can only be inspected serially. The judgment principle of the last segment code is specifically divided into two parts: the English part judgment and the digital part judgment. The judgment principle of the English part of the last segment code is: if the first segment code is the same and the English part has an inclusion relationship, or if the first segment code is different and the English part has a completely identical relationship, then the two areas cannot be inspected at the same time.
