本申请一实施例提供了一种反应堆容器1内熔融金属介质驱动浸入式取样系统，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统用于对反应堆容器1内的熔融金属介质取样，反应堆容器1内熔融金属介质驱动浸入式取样系统包括两端开口的取样管道10、金属缆绳20、卷筒30、驱动件40和取样容器50。取样管道10的一端用于伸入至反应堆容器1内熔融金属介质的液位以下，金属缆绳20至少部分可活动地穿设于取样管道10内，卷筒30和驱动件40均设于取样管道10外。金属缆绳20的一端卷绕于卷筒30，驱动件40与卷筒30连接，并用于驱动卷筒30旋转，以收卷或释放金属缆绳20，取样容器50连接于金属缆绳20的另一端。
上述反应堆容器1内熔融金属介质驱动浸入式取样系统，通过设置金属缆绳20和两端开口的取样管道10，且取样管道10的一端用于伸入至反应堆容器1内熔融金属介质的液位以下，使金属缆绳20能够穿过取样管道10进入反应堆容器1内。通过在取样管道10外设置卷筒30和驱动件40，使驱动件40驱动卷筒30旋转，使卷筒30收卷或释放金属缆绳20，从而改变卷筒30释放的金属缆绳20的长度，使连接于金属缆绳20另一端的取样容器50的位置改变，即，使取样容器50能够伸入至反应堆容器1的熔融金属介质内取样，并在取样完毕后移动至取样管道10外，以供拿取取样容器50并对其盛放的熔融金属介质样品进行检测及分析。由于设置金属缆绳20，使人员在取样时能够远离反应堆容器1，减小了取样过程中的放射性风险，使取样安全性提高。其中，熔融金属介质可以为铅铋介质。
需要说明的是，由于取样管道10是用于供金属缆绳20和取样容器50穿行的通道，而不是用于供熔融金属介质流动的通道，从而使取样管道10无需具备伴热功能以使熔融金属介质保持液态。如此，使反应堆容器1内熔融金属介质驱动浸入式取样系统的结构简化，成 本降低，并避免出现取样管道10的伴热功能不佳导致熔融金属介质固化而造成取样管道10堵塞。
在实际使用过程中，取样管道10伸入至反应堆容器1的一端伸入至熔融金属介质的液位以下，以为金属缆绳20提供导向作用，便于取样容器50伸入熔融金属介质的液位下进行取样。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括反应堆贯穿件60，取样管道10穿过反应堆贯穿件60。需要说明的是，反应堆贯穿件60为实现安全壳内外电缆或机械连接的装置。如此，通过设置反应堆贯穿件60，以为取样管道10提供进入反应堆厂房的通道。
在一些实施例中，取样管道10可以采用不锈钢无缝钢管。
在一些实施例中，如图1所示，取样管道10包括一端彼此连接的竖直段和水平段，竖直段和水平段交叉设置，且竖直段和水平段的连接处采用圆弧过渡，竖直端远离水平段的一端用于伸入至反应堆容器1内，卷筒30和驱动件40设于水平段外。如此，通过设置竖直段，使当取样容器50在反应堆容器1内取样后，在竖直段内不会倾倒导致取样容器50内的熔融金属介质样品洒出，并能够在竖直段内停留直至取样容器50内的熔融金属介质样品冷却固化。通过设置水平段，便于取样管道10的布置。通过设置竖直段与水平段的连接处圆弧过渡，以避免当取样容器50通过竖直段和水平段的连接处时受到阻碍。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括至少一个设置于取样管道10上的隔离阀70，以控制取样管道10的通断。如此，通过设置隔离阀70，使在反应堆容器1内熔融金属介质驱动浸入式取样系统未取样时，通过将隔离阀70关闭，实现对反应堆容器1内放射性气体的完整屏蔽。
在一些实施例中，如图1所示，隔离阀70的数量为两个，两个隔离阀70包括设置于竖直段的第一隔离阀71，以及设置于水平段的第二隔离阀72，以更有效地实现对反应堆容器1内放射性气体的屏蔽。
在实际使用过程中，可通过在不同的时刻分别关闭第一隔离阀71和第二隔离阀72，以进一步地减小反应堆容器1内放射性气体的泄露。例如，当需要取样时，打开第一隔离阀71和第二隔离阀72，并通过驱动件40驱动卷筒30旋转，以释放金属缆绳20，使金属缆绳20连接有取样容器50的一端穿过取样管道10，进入反应堆容器1内的熔融金属介质液位以下，使取样容器50收集所需的熔融金属介质样品。待取样容器50取样完毕，通过驱动件40驱动卷筒30反方向旋转以收卷金属缆绳20，使金属缆绳20将取样容器50提升至竖直段内。当金属缆绳20经过第一隔离阀71一定距离之后，关闭第一隔离阀71，并使驱动件40停止驱动，卷筒30停转，使取样容器50在取样管道10内以竖直状态保持静止，直至取样容器50内的熔融金属介质样品冷却至固态。然后使驱动件40继续驱动卷筒30旋转收卷金属缆绳 20，待取样容器50进入水平段并经过第二隔离阀72后，关闭第二隔离阀72，将取样容器50从金属缆绳20一端取下，以供检测分析。因此，上述取样过程中，通过使取样容器50在竖直段内停留一定时间，使取样容器50内的熔融金属介质样品固化，从而当取样容器50进入水平段后，不会因取样容器50倾倒而导致熔融金属介质样品洒出。此外，当熔融金属介质冷却固化后，其放射性大幅度减小，从而使取样容器50移至取样管道10外供人员拿取时，进一步地减小放射性风险。通过设置两个隔离阀70，使当取样容器50以竖直状态静止时，能够通过关闭第一隔离阀71，避免反应堆容器1内的放射性气体泄露过多，从而为取样容器50内熔融金属介质样品的固化提供充足时间。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括设于取样管道10内的密封组件80，密封组件80被配置为用于使金属缆绳20和取样管道10之间保持动态密封，或使取样管道10保持静态密封。如此，通过设置密封组件80，以进一步防止反应堆容器1内的放射性气体泄露。
在一些实施例中，当金属缆绳20和取样容器50在取样管道10中运行时，密封组件80使金属缆绳20和取样管道10之间保持动态密封，当金属缆绳20和取样容器50不位于取样管道10中时，密封组件80使取样管道10保持静态密封，从而在反应堆容器1内熔融金属介质驱动浸入式取样系统在不同状态下均具有较高的密封性。例如，当第一隔离阀71和第二隔离阀72打开时，密封组件80仍然能阻隔反应堆容器1内放射性气体的逸散。
在一些实施例中，如图1所示，密封组件80靠近取样管道10远离反应堆容器1的一端设置。
在一些实施例中，如图1所示，取样管道10包括取样总路11和分别与取样总路11连通的多个取样支路12，卷筒30和驱动件40设于取样总路11外，取样支路12远离取样总路11的一端用于伸入至反应堆容器1内。如此，通过设置分别与取样总路11连通的多个取样支路12，使多个取样支路12各自远离取样总路11的一端能够伸入至反应堆容器1内的不同位置，以实现对反应堆容器1内熔融金属介质的多点取样，以更全面地获取熔融金属介质的信息，使获取的熔融金属介质样品更具有代表性。在实际取样过程中，每次取样前更换与金属缆绳20连接的取样容器50，并使多个取样容器50经过取样总路11后进入不同的取样支路12，从而对反应堆容器1内不同位置的熔融金属介质取样。
可以理解的是，取样支路12的数量可以根据对反应堆容器1内取样位置的数量要求设置，在此不做限定。
在一些实施例中，密封组件80设置于取样总路11上。
在一个实施例中，如图1所示，取样支路12包括取样管道10的竖直段和部分水平段，取样总路11包括水平段的另一部分。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还 包括选路装置90。选路装置90上设有进口91和分别与进口91连通的多个出口92，取样总路11与取样支路12连接的一端连接于进口91，取样支路12与取样总路11连接的一端一一对应地连接于出口92。如此，通过设置选路装置90，以使取样总路11借助于选路装置90分别与多个取样支路12连通，并防止反应堆容器1内的放射性气体从取样总路11与多个取样支路12的连接处泄露。此外，设置选路装置90，还便于金属缆绳20和取样容器50选择所要进入的取样支路12。多次取样时，可使不同的取样容器50通过选路装置90，依次进入到不同的取样支路12中进行取样。
为便于更换取样容器50，取样容器50与金属缆绳20可拆卸地连接。
在一个实施例中，金属缆绳20的周向侧壁上设有外螺纹，取样容器50的内壁设有内螺纹，金属缆绳20与取样容器50螺纹连接。另在一些实施例中，金属缆绳20和取样容器50也可采用其他连接方式，只要实现金属缆绳20与取样容器50的可拆卸连接即可，在此不做限定。
图2为本申请一实施例中金属缆绳和取样容器的装配示意图。
在一些实施例中，如图2所示，取样容器50的一端与金属缆绳20连接，以减小金属缆绳20在取样容器50内的占用空间，使取样容器50内具有较大空间，以容纳熔融金属介质样品。
在一些实施例中，如图2所示，取样容器50与金属缆绳20连接的一端设有取样孔51。如此，通过设置取样孔51，以当取样容器50浸入反应堆容器1内的熔融金属介质以下时，熔融金属介质从取样孔51中流进取样容器50，使取样容器50收集熔融金属介质样品的过程简便，并使取样容器50的结构简单。通过将取样孔51设于取样容器50与金属缆绳20连接的一端，使取样容器50在竖直状态下具有用于容纳熔融金属介质样品的较大空间，从而较大限度地利用了取样容器50的体积。
在一些实施例中，如图2所示，取样容器50远离金属缆绳20的一端被构造为呈外凸的圆弧状，以当取样容器50进入反应堆容器1内的熔融金属介质时，减小取样容器50所受到的阻力，从而便于取样。
应当理解的是，取样容器50的尺寸被构造为与取样管道10的内径尺寸适应，以使取样容器50能够在取样管道10中顺畅移动。
在一些实施例中，取样容器90的内壁涂覆有耐腐蚀防粘附涂层，以防止熔融金属介质对取样容器90的腐蚀导致熔融金属介质样品污染，并防止熔融金属介质过多地粘附在取样容器90内。
在一些实施例中，取样容器90的材质可以采用不锈钢。
在一些实施例中，金属缆绳20的表面涂覆有耐腐蚀防粘附涂层，以避免熔融金属介质在金属缆绳20上的粘附，降低取样管道10内以及驱动件40和卷筒30处的放射性水平， 提高取样安全性。
在一些实施例中，金属缆绳20被构造为呈螺旋状。
可以理解的是，驱动件40被配置为能够分别驱动卷筒30正转和反转，当卷筒30正转时，卷筒30释放金属缆绳20，当卷筒30反转时，卷筒30收卷金属缆绳20。
在一些实施例中，驱动件40可以采用齿轮电动机，以提供足够动力驱动金属缆绳20和取样容器50在反应堆容器1内和驱动件40之间来回运行。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括设于卷筒30上的编码器，编码器用于获取由卷筒30上所释放的金属缆绳20的长度及卷绕至卷筒30上的金属缆绳20的长度。如此，通过设置编码器，以通过卷筒30上释放的金属缆绳20的长度得到金属缆绳20远离卷筒30的一端在取样管道10内的位置，以便实现对取样容器50的位置的精准控制。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括罩设于卷筒30和驱动件40的取样箱100，取样管道10远离反应堆容器1的一端伸入至取样箱100内。如此，通过设置取样箱100，且卷筒30和驱动件40均位于取样箱100内，避免放射性熔融金属介质逸散到环境中造成污染。在实际取样过程中，盛放了熔融金属介质样品的取样容器50通过取样管道10远离反应堆容器1的一端进入取样箱100内，人员在取样箱100中完成取样容器50与金属缆绳20的拆装，避免人员与取样容器50直接接触。
在一些实施例中，取样箱100可以采用成套取样手套箱，以使人员能够半自动获取取样箱100内的取样容器50，避免人员直接近距离接触盛放熔融金属介质样品的取样容器50，影响人员安全。
在一些实施例中，取样箱100内维持微负压，以避免放射性气体熔融金属介质释放到环境中。
在一个实施例中，取样箱100的材质采用含铅材料。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括屏蔽板110，屏蔽板110设于取样箱100内，且贴附于取样箱100的一侧。如此，通过设置屏蔽板110，以屏蔽取样容器50的辐射，提高对人员的防护。
应当理解的是，屏蔽板110贴附于取样箱100用于供人员拿取取样容器50的一侧，从而当人员在操作时，取样容器50、金属缆绳20及驱动件40等设备均位于屏蔽板110后，减少人员受到的辐照剂量。
在一些实施例中，屏蔽板110的材质采用含铅材料。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括第一气体分配系统。第一气体分配系统包括惰性气源121、一端与惰性气源121连接的第一管道122，以及设于第一管道122的第一阀门123，第一管道122的另一端伸入至取样箱 100内，第一阀门123用于控制第一管道122的通断。如此，通过设置第一气体分配系统，使惰性气源121提供的惰性气体通过第一管道122进入取样箱100内，并覆盖取样箱100内部，防止取样容器50内盛放的熔融金属介质样品受到污染，从而使通过检测分析熔融金属介质样品所得到的信息能够准确体现反应堆容器1中的熔融金属介质状态。
在一些实施例中，惰性气源121被配置为能够提供氩气。另在一些实施例中，惰性气源121也可根据使用需要而被配置为提供其他惰性气体，在此不做限定。
在一些实施例中，如图1所示，反应堆容器1内熔融金属介质驱动浸入式取样系统还包括第二气体分配系统和废气处理系统140。第二气体分配系统包括压缩空气气源131、一端与压缩空气气源131连接的第二管道132，以及设于第二管道132的第二阀门133，第二管道132的另一端伸入至取样箱100内，第二阀门133用于控制第二管道132的通断。废气处理系统140具有伸入至取样箱100内的第三管道141。如此，通过设置第二气体分配系统，压缩空气气源131提供的压缩空气能够通过第二管道132进入取样箱100内，将取样箱100内的放射性废气通过第三管道141吹扫至废气处理系统140内，以便对取样箱100及其内部设备进行维护，避免放射性废气造成环境污染。
应当理解的是，在取样过程中，第一阀门123开启，第二阀门133关闭，使取样箱100内实现惰性气体覆盖，并避免压缩空气污染熔融金属介质样品。
因此，本申请提供的反应堆容器1内熔融金属介质驱动浸入式取样系统，在实际取样过程中，先打开第一隔离阀71和第二隔离阀72，驱动件40驱动卷筒30旋转释放金属缆绳20，使金属缆绳20带动取样容器50经过取样管道10进入反应堆容器1的熔融金属介质液位以下收集熔融金属介质。待取样容器50收集了所需的熔融金属介质样品，驱动件40驱动卷筒30反转以收卷金属缆绳20，使取样容器50在取样管道10的竖直段内运动，直至取样容器50经过第一隔离阀71一定距离后，驱动件40停止驱动。此时，关闭第一隔离阀71，取样容器50保持竖直状态静置，待取样容器50内的熔融金属介质样品冷却至固态后，重新开启驱动件40，以使卷筒30继续收卷金属缆绳20，使金属缆绳20带动取样容器50移动至取样箱100内。然后关闭第二隔离阀72，并将取样容器50从金属缆绳20上取下，送去检测分析。在金属缆绳20上安装新的取样容器50，并可将取样容器50驱动至密封组件80位置处，待下次取样时使用。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。 因此，本申请专利的保护范围应以所附权利要求为准。
