摘要：【中文】本发明公开了一种堆芯冷却系统以及方法，系统包括双层安全壳、反应堆存水坑、压力容器以及蒸汽发生器，双层安全壳包括安全壳内、外墙，内、外墙之间形成至少一个存储冷却剂的冷却水腔室，核电厂发生全厂断电事故时，稳压器专用释放阀和注水阀被打开，注水管道向压力容器注入冷却剂，释放管道将从堆芯进入热管段中的蒸汽、汽水混合物或者冷却剂排放到反应堆存水坑内，当反应堆存水坑的水位上升至第一高度时，注水阀被关闭并且回流注入阀被打开，反应堆存水坑内的部分冷却剂通过回流注入管道回流进入压力容器与堆芯，反应堆存水坑的水位降低到第二高度时，注水阀被打开并且回流注入阀被关闭，如此压力容器内外可以实现同时冷却效果，且节约冷却剂。 【EN】The invention discloses a reactor core cooling system and a method, the system comprises a double-layer containment, a reactor storage water pit, a pressure vessel and a steam generator, the double-layer containment comprises an inner containment wall and an outer containment wall, at least one cooling water chamber for storing coolant is formed between the inner containment wall and the outer containment wall, when a power failure accident of a nuclear power plant occurs, a release valve and a water injection valve special for a voltage stabilizer are opened, a water injection pipeline injects the coolant into the pressure vessel, the release pipeline discharges the steam, steam-water mixture or the coolant entering a heat pipe section from a reactor core into the reactor storage water pit, when the water level of the reactor storage water pit rises to a first height, the water injection valve is closed and the reflux injection valve is opened, part of the coolant in the reactor storage water pit flows back into the pressure vessel and the reactor core through the reflux injection pipeline, and when the water level of the reactor storage water pit is reduced to a second height, the water injection valve is opened and the backflow injection valve is closed, so that the simultaneous cooling effect can be realized inside and outside the pressure vessel, and the coolant is saved.

摘要：【中文】本发明公开了一种乏燃料冷却系统，包括：底部注水系统、顶部抽水系统以及热交换系统，所述顶部抽水系统和底部注水系统分别连接所述热交换系统，所述顶部抽水系统从乏燃料水池的顶部抽水并送往热交换系统进行换热，所述底部注水系统将所述热交换系统换热后的冷却水从所述乏燃料水池的底部注入所述乏燃料水池，如此可以预防和缓解乏燃料在乏池高温注水时发生熔化；进一步的，底部注水系统包括注水管网，其包括多个出水管口，每一个乏燃料组件的底部均开设有一个安装所述出水管口的注水孔，如此注入的冷却剂通过注水管网注入到每一个乏燃料组件的底部，避免了乏燃料熔化和放射性释放到环境危害环境居民的生命与财产安全。 【EN】The invention discloses a spent fuel cooling system, which comprises: the system comprises a bottom water injection system, a top water pumping system and a heat exchange system, wherein the top water pumping system and the bottom water injection system are respectively connected with the heat exchange system, the top water pumping system pumps water from the top of the spent fuel pool and sends the water to the heat exchange system for heat exchange, and the bottom water injection system injects cooling water subjected to heat exchange of the heat exchange system into the spent fuel pool from the bottom of the spent fuel pool, so that the spent fuel can be prevented and relieved from being melted during high-temperature water injection of the spent pool; further, bottom water injection system includes the water injection pipe network, and it includes a plurality of water outlet pipe mouths, and an installation has all been seted up to the bottom of each spent fuel subassembly the water injection hole of water outlet pipe mouth, the coolant that so injects into the bottom of each spent fuel subassembly through the water injection pipe network, has avoided the spent fuel to melt and the radioactivity releases life and property safety to the environment harm resident.

摘要：【中文】本发明公开了一种用于核电站全范围模拟机的语音报警广播仿真方法，包括：运行客户端程序加载语音报警信息；根据语音报警信息打包订阅数据，向服务端发送数据订阅请求；服务端根据数据订阅请求，查询仿真平台，并将获取的监测数据发送至对应的客户端；在返回的监测数据触发报警事件时，生成并播报报警事件队列，记录并显示报警日志。本发明解决了过去的语音报警功能可靠性差的问题，播报准确，响应及时。同时，根据用户需求实现不同区域房、不同的主机播报不同内容的音频，实现差异化播报。此外，支持用户和维护人员通过简单的文本编辑方式实现对不同语音文件的播放逻辑设定，实现对语音播报内容、播报次数，以及顺序的控制。 【EN】The invention discloses a voice alarm broadcasting simulation method for a nuclear power station full-range simulator, which comprises the following steps: operating a client program to load voice alarm information; packing subscription data according to the voice alarm information, and sending a data subscription request to a server; the server side inquires the simulation platform according to the data subscription request and sends the acquired monitoring data to the corresponding client side; and when the returned monitoring data trigger an alarm event, generating and broadcasting an alarm event queue, and recording and displaying an alarm log. The invention solves the problem of poor reliability of the traditional voice alarm function, and has accurate broadcast and timely response. Meanwhile, different regional rooms and different hosts broadcast different audio frequencies according to user requirements, and differential broadcast is achieved. In addition, the method supports users and maintenance personnel to realize the playing logic setting of different voice files through a simple text editing mode, and realizes the control of voice broadcast contents, broadcast times and sequence.
