Supervision and construction of nuclear power quality program management control points
Quality program is the main quality control means of nuclear power construction construction activities. Here is what I share with you to supervise the construction of nuclear power quality program management control points, welcome to read and browse.
1 Introduction
With the great development of China's nuclear power cause, many engineers and technicians to participate in the nuclear power construction team, as China's nuclear power construction supervision of the main team? Beijing Sida Bex Engineering Supervision Co., Ltd, engineering supervision team is also growing dramatically. As the main mode of quality control in nuclear power construction? quality program? Most of the engineers and technicians who have just participated in the supervision of nuclear power construction have no contact with it, and its source is not well understood, in the supervision process of quality control of the plan is a person a law, there is no guiding basis, according to their own experience and experience, to discuss the nuclear power construction supervision of quality control personnel on the quality of the plan for the management and control.
2 quality plan definition and characteristics
2.1 Definition
According to GBT19000-2008 quality management system basis and terminology standards, the quality plan for a product, project or contract, the provisions of special quality measures, resources and sequence of activities of the document. The quality plan in this paper refers to the planned documents for checking, testing or verifying the construction quality at the nuclear power construction site.
2.2 Features
The main mode of nuclear power construction quality control? Quality plan, was introduced with the Sino-French cooperation in the construction of Daya Bay nuclear power plant, at this stage it generally contains the following features:
2.2.1 quality plan is the basis for the construction unit of external quality assurance (general contracting management company or the owner) and internal quality control;
2.2.2 quality plan is generally compiled by the technical department of the construction unit, the construction unit of the quality inspection department audit Preparatory work;
2.2.4 Due to the complexity of nuclear power construction projects and high standards, in order to strengthen its operability and from the quality management and quality control, the quality of the content of the plan for the target is generally equivalent to the civil construction or industrial installation projects in the division or sub-division of the project, reflecting the work process, test batches, sub-projects, sub-projects, the process of controlling, reflected from the resources to the completion of the final inspection of project quality and quality of the project. Input to the completion of the project quality of the final inspection and testing of the whole process control;
2.2.5 quality plan with the construction unit's mode of operation and target complexity. )
2.2.6 The format and detailed procedures of the quality plan with the construction (or general contracting management company) unit of the relevant procedural requirements, and with the construction unit of the internal quality system assurance documents - quality assurance manual, procedural documents, construction program, etc. compatible.
2.3 Quality Program Status
The status of the quality program used in nuclear power construction is divided into stages of execution, initiation, implementation, and closure.
3 Construction Supervision of the quality plan management control
3.1 Construction Supervision of the quality plan management control responsibilities
Generally based on the owners of nuclear power projects, "quality plan interface management program," the construction units according to this program, which provides for their respective division of responsibility for the preparation of their respective "quality plan management program"; nuclear power project owners "quality plan interface management program"; nuclear power construction units according to their respective division of responsibilities for the preparation of their respective "quality plan management program"; nuclear power construction of the state of the use of quality plans are divided into stages.
3.2 Nuclear Power Construction Supervision of quality plan management control authority
Nuclear Power Construction Supervision of the exercise of the duties of the unit to just graduated from the school graduates, from the construction unit, the construction unit to the nuclear power supervision of the unit's engineering and technical personnel and from the general civil supervision industry to the nuclear power supervision of the unit's engineering and technical personnel to grasp the existence of a great deal of difficulty; one is the role of transfer to make the We are offside: either become the construction unit of the quality inspector, or rash decision-making for the construction unit; Secondly, the quality of the quality control model of the quality plan is not very familiar with. In short, we should grasp the two principles: one is clear that the construction unit is the implementation of the main quality plan, the main body of responsibility, supervision units to exercise the supervision of engineering quality plan responsibility, is the service unit; the second is the construction unit is the main body of responsibility for the construction project, the construction project quality plan for the confirmation of the quality standard is responsible for the supervision of the unit only supervision, advice, service rights, no decision-making power.
4 nuclear power construction supervision of the quality plan review, approval management control
4.1 nuclear power construction supervision of the quality plan review principles
The review of the quality plan requirements (including, but not limited to) mainly from the following aspects:
4.1.1 whether the quality assurance level and design documents Consistent;
4.1.2 Job content and steps are not missing;
4.1.3 Sequence of operations is consistent with the construction program or work procedures;
4.1.4 Operation based on the documents are correct and valid;
4.1.5 Responsible construction unit quality control department to select the point of whether it is accurate, there are no omissions. In principle, the responsible construction unit's selection of points should fully cover the control points set by the quality control department of the supervisory company, and the level of the control points can not be reduced;
4.1.6 Whether the preparation, review and approval of the signatures are complete.
4.2 Nuclear Power Construction Supervision of the quality plan review focus
The most important review of the quality plan should be the content of the above point 2), that is, the quality plan to control the contents of the operation and the steps of the omission of the quality plan to control the contents of the operations of the essence of the quality plan to control the contents of the operation should be the quality plan of the quality control points set up is complete, it is the core of the preparation of the quality plan is Construction unit quality inspection department, supervision units, construction units (general contracting management company) quality plan to select the basis of the point.
Secondly, we must pay attention to the quality of the plan to control the order of setting points to ensure that the order of setting quality control points in line with the actual site construction (such as civil waterproofing construction, welding, equipment installation, equipment commissioning, lifting operations, etc.) process, quality control (quality inspection methods and measures, tools, environment, etc.) requirements. Special attention is paid to the specific technical specifications, manufacturer's documents, drawings, etc. in line with the description. For example, Hainan Changjiang nuclear power plant KX plant 130 tons of spent fuel container crane rail pressure plate installation quality plan, according to the original manufacturer's documentation: rail pressure plate base first welded and then through the adjustment mechanism to complete the track. Adjustment, quality control points set in the order of first checking the rail pressure plate welding quality, and then set the rail adjustment quality control points. But in the manufacturers of track pressure plate into the field after the opening of the box found that the field pressure plate and the original map is not consistent, the installation type into the first through the drilling of holes in the track beam, by the track pressure plate first positioning, bolt tightening to complete the adjustment of the track, and then complete the track pressure plate adjustment plate and the base plate of the weld, so that the track pressure plate installation and adjustment of the track pressure plate welding of the two quality control points of the order of the reversed.
4.3 nuclear power construction supervision of quality plan review of technical preparation
In summary, to complete the review of the construction unit quality plan, supervision engineers should first of all the quality plan involves construction drawings, construction instructions, (civil engineering, prefabrication, installation, procurement, testing, etc.) technical specifications, items (such as cement-based grout, welding materials, anticorrosive materials) manuals Equipment installation and commissioning manufacturer's documents, approved processes (such as waterproofing, welding, painting, insulation, electrical commissioning, rotating equipment test run, the second grouting operations, lifting equipment load test operations, process piping test pressure flushing operations, important equipment on-site assembly, etc.) and other design and construction documents such as operating instructions for careful review, the quality plan involves quality control content The quality control program involves quality control content, quality control standards, quality control procedures, etc. to do a good understanding.
As a nuclear power construction professional supervision engineers, but also must be familiar with the construction quality acceptance system knowledge, such as civil construction, "building construction quality acceptance standard" (GB50300-2001) and its supporting civil engineering, installation of various divisions of professional construction quality acceptance of construction specifications, such as GB50202-2002, GB50203-2002 GB50202-2002, GB50203-2002, GB50204-2002, GB50205-2001, GB50206-2003, GB50242-2002, GB50268-2008, GB50243-2003 and so on professional quality acceptance specifications, and industrial installation acceptance of the applicable "Uniform Standards for Quality Acceptance of Industrial Installation Projects" (GB50252-2010) and its supporting professional construction quality acceptance specifications. (GB50252-2010) and its supporting professional installation engineering construction quality acceptance specifications such as GB50231-2009, GB50236-98, GB50235-2010, GB50275-2010, GB50270-2010, GB50273-2009, GB50274-2010, GB50278-2010, GB50309-2007 and so on construction quality acceptance specification, in order to master the acceptance of each professional sub-projects construction content, acceptance criteria, acceptance process, only then can the quality control points set up to accurately grasp.
4.4 Nuclear Power Construction Supervision on the quality of the plan to select the management control
The so-called quality of the plan to select the point, refers to the quality of the plan in the selection of quality control points, quality control points are in order to ensure the quality of the process of work to determine the focus of the control object, the key parts and weak links. Supervision engineers should draw up the quality control work plan according to the construction content, quality of construction team, construction environment and quality standards involved in the quality plan, and make clear the key processes affecting the quality, such as tensioning of prestressed structure, erection of steel bars in reinforced concrete structure, prefabricated welding of process pipelines, hoisting and in-situ installation of main equipment of the nuclear island, and other processes, parts, or objects, such as underground waterproofing layer construction, construction of the weak points or the processes of unstable quality. or objects, such as the construction of underground waterproof layer, the processing of component welding bevels, the construction of subsequent works or the quality of subsequent processes or safety have a significant impact on the process, parts or objects, such as engineering measurement and positioning, surface pretreatment before painting metal components, the quality of reinforcing steel in the construction of concrete structures, the template of the support and fixation, the process of installing bracket installation, and other control priorities. Only in this way can we achieve the quality control point selection neither to improve the standard of inspection and witnessing, but also to meet the quality control objectives.
4.5 Nuclear power construction supervision of the quality plan to select the point of management control of the general principles
4.5.1 The following process operations, should be set up to stop work to be inspected point (H point):
1) the start of the quality plan? Start-up prerequisite check;
2) Quality program closure? Comprehensive inspection of completion records;
3) Processes that will be covered by the next process, as well as processes that cannot be repaired after the completion of the process, i.e., hidden points;
4) Construction operations that have a greater impact on safety and utilization or are technically difficult;
5) Construction operations in which the subsequent process is a special process;
6) Measurement and positioning of the construction process. Horizontal, vertical check.
4.5.2 The following process operations, generally should be set up to witness the point (W point):
1) special process operation of the inspection, non-destructive testing, etc.;
2) the treatment of the construction joints;
3) equipment lifting;
4) the site of the installation of important equipment in place, grouping;
5) the rotating equipment of the stand-alone test run
6) Functional test of equipment.
4.5.3 After the operation of the construction process, with construction records, reports are sufficient to prove the quality of construction processes, generally set the document review point (R point).
4.5.4 Specific selection of points, based on the above principles, H points generally can not be downgraded; W points can be upgraded to H points or downgraded to R points according to the specific circumstances, according to the confidence of the responsible construction unit. The above is only a general principle, the specific selection of points by the supervisory engineer discretionary consideration.
