Description

核电站安全壳钢内衬鼓包边界的确定方法和确定装置Method and device for determining bulging boundary of steel lining of nuclear power plant containment 技术领域Technical field
本发明属于核电技术领域，更具体地说，本发明涉及一种核电站安全壳钢内衬鼓包边界的确定方法和确定装置。The invention belongs to the technical field of nuclear power. More specifically, the invention relates to a method and a device for determining the bulging boundary of the steel lining of the containment vessel of a nuclear power plant.
背景技术Background technique
核电站安全壳是带有准球形穹顶的圆柱形预应力钢筋混凝土结构，是阻挡来自燃料的裂变产物和一回路放射性物质进入环境的最后一道屏障。反应堆发生失水事故(LOCA：Loss of Coolant Accident)后，释放出来的大量放射性和高温高压汽水混合物可被安全壳包容和隔离，防止对核电站周围居民产生危害。The nuclear power plant containment is a cylindrical prestressed reinforced concrete structure with a quasi-spherical dome. It is the last barrier to prevent fission products from fuel and primary radioactive materials from entering the environment. After a loss of water accident (LOCA: Loss of Coolant Accident) occurs in the reactor, a large amount of radioactivity and high-temperature and high-pressure steam-water mixture released can be contained and isolated by the containment to prevent harm to residents around the nuclear power plant.
钢内衬是安全壳内壁上附着的一层钢板，是安全壳密封性的重要保证。钢内衬由焊接在钢内衬上的铆钉连接在安全壳混凝土结构上，钢内衬一般情况下与混凝土贴合较好，不会发生空鼓现象。但是，由于钢内衬施工技术复杂、施工周期长，加之安全壳混凝土收缩、预应力张拉施工工艺等原因，钢内衬可能会与混凝土结构剥离，发生鼓包现象。鼓包是钢内衬最普遍的缺陷类型，对安全壳的完整性不利，过大过高的鼓包对核安全第三道屏障的安全性有着严重影响，需要对其进行检查、记录、跟踪。The steel lining is a layer of steel plate attached to the inner wall of the containment, which is an important guarantee for the tightness of the containment. The steel lining is connected to the concrete structure of the containment by rivets welded to the steel lining. Generally, the steel lining fits well with the concrete and will not cause hollowing. However, due to the complex construction technology of the steel lining, the long construction period, and the shrinkage of the containment concrete and the prestressing construction process, the steel lining may peel off from the concrete structure and cause bulging. Bulges are the most common type of defects in steel linings, which are detrimental to the integrity of the containment. Bulges that are too large or too high have a serious impact on the safety of the third nuclear safety barrier and need to be inspected, recorded, and tracked.
安全壳试验(containment test，CTT)广泛用于模拟验证安全壳在大破口失水(LOCA)事故条件下的密封能力，对于保障核电站的运行有非常重要的意义，在机组建设阶段和机组运行阶段均需要进行试验。CTT前后的安全壳内表面内观检查的一个重要工作内容就是确认钢内衬鼓包的边界，以便在安全壳寿期内对鼓包进行跟踪，评估钢内衬的工作性能。The containment test (CTT) is widely used to simulate and verify the containment capability of the containment under the conditions of a large break loss of water (LOCA) accident. It is of great significance for ensuring the operation of nuclear power plants, during the unit construction phase and the unit operation phase All need to be tested. An important part of the internal inspection of the inner surface of the containment vessel before and after CTT is to confirm the boundary of the steel lining bulge, so as to track the bulge during the life of the containment and evaluate the performance of the steel lining.
现有技术通常利用木槌采用人工敲击听音的方式寻找鼓包边界，具体操作 步骤如下：The prior art usually uses a mallet to find the boundary of the drum kit by manually tapping the sound. The specific operation steps are as follows:
1.人工手持木槌，逐点敲击钢内衬，寻找鼓包。一般情况下，钢内衬若未与混凝土发生剥离，则敲击声音较为沉闷；若有剥离现象，则敲击时则会发出响亮、清脆的声音(声音类似于敲击瓷砖空鼓的声音)；1. Manually hold the mallet and tap the steel lining point by point to find the bulge. Under normal circumstances, if the steel lining does not peel off from the concrete, the percussion sound will be dull; if there is peeling, it will make a loud and crisp sound when struck (the sound is similar to the sound of percussion on a tile hollow drum) ；
2.找到鼓包后，在鼓包内和鼓包外分别敲击鼓包，根据经验判断鼓包边界，并用记号笔标记鼓包在此处的边界；2. After finding the drum kit, hit the drum kit inside and outside the drum kit separately, judge the boundary of the drum kit based on experience, and mark the boundary of the drum kit here with a marker;
3.重复上述边界点寻找步骤，依次标记鼓包边界点，直至找到完整的鼓包边界；3. Repeat the above steps of finding the boundary point, marking the boundary points of the bulge in sequence until the complete boundary of the bulge is found;
4.使用记号笔将前述边界点连起来，构成封闭的曲线，封闭的曲线即为鼓包边界。4. Use a marker to connect the aforementioned boundary points to form a closed curve, and the closed curve is the bulge boundary.
但是，现有技术的核电站安全壳钢内衬鼓包边界的确定方法至少存在以下缺陷：However, the prior art method for determining the bulging boundary of the containment steel lining of nuclear power plants has at least the following defects:
1.工作效率低：检测人员完成一个边界点的确认后，需要停下来使用记号笔标记边界点，一个中等大小鼓包(0.5m 2)的检测需要耗时10分钟左右，一般情况下，一个安全壳钢内衬约有300个鼓包，总共耗时约为3000分钟； 1. Low work efficiency: After the inspector has completed the confirmation of a boundary point, he needs to stop and use a marker to mark the boundary point. The inspection of a medium-sized bulge (0.5m 2 ) takes about 10 minutes. Generally, a safe The shell steel lining has about 300 bulges, and the total time is about 3000 minutes;
2.鼓包边界精度低：对于剥离区域(即鼓包)和未发生剥离的区域，敲击声音由“清脆”变化至“沉闷”，声音频率由高到低，但该频率变化较为连续，因此边界点的确认较为主观，不同经验的检测人员确认的边界点差异较大，最终绘制的鼓包边界也有较大差别；2. Low accuracy of the bulge boundary: For the peeled area (ie bulge) and the area where no peeling occurs, the percussion sound changes from "clear" to "dull", and the sound frequency changes from high to low, but the frequency change is relatively continuous, so the boundary The point confirmation is more subjective, the boundary points confirmed by different experienced inspectors are quite different, and the final drawn bulge boundary is also quite different;
有鉴于此，确有必要提供一种高效、可靠的核电站安全壳钢内衬鼓包边界的确定方法和确定装置。In view of this, it is indeed necessary to provide an efficient and reliable method and device for determining the bulging boundary of the steel lining of the containment vessel of nuclear power plants.
