具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
反应堆是核电厂根据一定物理现象实现发电的装置，为获取反应堆原型特别是事故下的运行特性，通常基于一定的模化分析手段保证实验模型能够反映反应堆原型的关键物理现象，此时则要求对于反应堆原型中的物理现象进行识别，保证没有遗漏。在反应堆安全分析软件开发中同样要求相应的软件能够模拟、计算、分析反应堆原型的关键物理现象，同样涉及到反应堆原型中的物理现象识别。因此，开发一种反应堆物理现象识别方法，对反应堆原型中的物理现象进行全要素分析，可以实现对于反应堆原型中物理现象的全面识别，对于反应堆热工水力实验与反应堆安全分析软件开发等都由十分重要的意义。
相关技术中，通常根据专家经验得到PIRT(Phenomena identification and ranking table，现象识别与排序表)，根据PIRT进行反应堆物理现象的识别。然而，人工经验有限，仅支持单个物理现象的识别，而无 法建立单个物理现象在整个物理进程中的作用与联系，无法保证反应堆物理现象识别的全面性。
在一个实施例中，如图1所示，提供了一种反应堆建模数据获取方法，本申请实施例以该方法应用于终端进行举例说明，可以理解的是，该方法也可以应用于服务器，还可以应用于包括终端和服务器的系统，并通过终端和服务器的交互实现。本实施例中，该方法包括以下步骤：
步骤101，对于待进行物理现象识别的目标反应堆所涉及到的各工作进程所包含的装置分别进行层级划分处理，得到各工作进程分别对应的层级划分结果。
其中，将需要建立模型的反应堆作为目标反应堆，在建立目标反应堆的模型之前，需要识别目标反应堆所进行的物理现象。目标反应堆例如可以为三环路压水堆、两环路压水堆、铅铋堆、钠堆、一体化自然循环堆等堆型。其中，目标反应堆包含多个装置，各装置例如为管道、分离器、干燥器等装置。目标反应堆可以实现不同的多个工作进程，目标反应堆的工作进程例如为小破口事故进程或大破口事故进程。
对于目标反应堆，通过所包含的多个装置实现各工作进程。对于各工作进程，确定实现该工作进程所涉及的多个装置，即，该工作进程所包含的装置。可选的，可根据各装置在该工作进程中所起的作用，对该工作进程包含的各装置进一步进行层级划分，从而得到该工作进程包含的各装置的层级划分结果。可选的，终端可获取目标反应堆的各工作进程对应的装置数据文件，根据该装置数据文件中的各装置的参数数据，确定各装置在该工作进程中的作用。
步骤102，对于各工作进程对应的层级划分结果，将该层级划分结果中最低层级所包含的装置进行控制体划分，得到初始划分结果，该初始划分结果包括多个第一控制体；其中，该第一控制体包括结构相同的至少一个装置。
其中，层级划分结果包括各装置所属的层级，各层级具有包含关系，例如，所属第一层级的装置可进一步划分为第二层级，所属第二层级的装置可进一步划分为第三层级，其中，第三层级即为最低层级。
对于最低层级的所包含的装置，根据各装置的结构特征，将结构特征相同的装置划分为一个控制体，得到多个第一控制体，即，第一控制体包含至少一个结构相同的装置。各第一控制体的划分结果即为各工作进程所包含的装置的初始划分结果。
步骤103，对于各初始划分结果，根据物理现象识别表对该初始划分结果进行修正处理，得到目标划分结果，该目标划分结果包括多个第二控制体；其中，该第二控制体包括结构相同且与同一物理现象相关的至少一个装置。
其中，物理现象识别表中包含有目标反应堆实现的各物理现象以及实现各物理现象的装置的对应关系。终端可根据该物理现象识别表，对初始划分结果进行识别修正。对于各第一控制体，将涉及同一物理现象的装置划分为同一第二控制体，得到多个第二控制体，因此，各第二控制体包括结构特征相同且与同一物理现象相关的至少一个装置。例如，对于长度相同且物理现象相同的管道可划分为一个第二控制体。各第二控制体的划分结果即为各工作进程所包含的装置的目标划分结果。
步骤104，根据各第二控制体以及各第二控制体相关的物理现象，生成与该目标反应堆对应的建模数据。
其中，对于目标划分结果，根据各第二控制体包含的装置，以及各第二控制体对应实现的物理现象，生成与目标反应堆对应的建模数据，该建模数据包含每一控制体与每一物理现象之间的对应关系。根据该建模数据，可进一步对目标反应堆进行模型建立，从而可以在建立的模型中模拟目标反应堆的可实际发生的各物理现象。
上述反应堆建模数据获取方法中，通过对待进行物理现象识别的目标反应堆所涉及到的各工作进程所包含的装置分别进行层级划分处理，通过层级一步步划分，以对复杂的目标反应堆包括的多个装置进行初始划分，从而可以根据各工作进程对应的层级划分结果，对层级划分结果中最低层级所包含的装置进行控制体划分而得到包括多个第一控制体的初始划分结果，实现将复杂的目标反应堆包括的多个装置划分为结构相同的多个第一控制体，建立了物理现象识别的最小分析单元，实现了目标反应堆物理现象识别的由繁化简，因此，可进一步根据物理识别现象表对该初始划分结果中的各第一控制体进行修正处理，从而得到多个第二控制体均结构相同且实现的物理现象相同；由于初始划分结果根据目标反应堆的各工作进程所包含的多个装置划分得到，因此，全面包含了目标反应堆的所有装置，通过对初始划分结果根据物理现象划分表进行修正，得到各第二控制体以及各第二控制体的物理现象，保证对目标反应堆的物理现象识别的全 面性和准确性，建立每一物理现象与整个工作进程的联系，为建立目标反应堆对应的实体模型提供准确的建模数据，从而有效降低建立模型与原始反应堆之间的差距。
在一个实施例中，如图2所示，其示出了本申请实施例提供的一种层级划分处理的流程示意图；对于待进行物理现象识别的目标反应堆所涉及到的各工作进程所包含的装置分别进行层级划分处理，包括：
步骤201，确定该目标反应堆的时间进程；其中，该时间进程包括针对该目标反应堆的物理现象的起始时间和结束时间。
其中，目标反应堆的各工作进程为某一时间段内发生的，因此，对于各工作进程所包含的装置的层级划分，应针对该时间段内所涉及的装置进行。其中，该时间段即为目标反应堆的时间进程，包括起始时间和结束时间，起始时间为该目标反应堆的物理现象开始发生的时间，结束时间为该目标反应堆的物理现象结束的时间。例如，可以将中小破口事故的破口发生时间作为时间进程中的起始时间，将余热排出换热器接入时的时间作为结束时间。
步骤202，在该时间进程内，确定各工作进程的目标状态类型；其中，该目标状态类型为瞬态类型或稳态类型。
其中，在该时间进程内，通过进一步确定各工作进程的目标状态类型，从而确定各工作进程实现不同物理现象所涉及的装置，并可进一步对各装置进行层级划分。
各工作进程所包含的装置的参数例如包括温度、压力、流量、功率等。目标状态类型可以为瞬态类型或稳态类型。若各参数在时间进程内，随时间的变化而变化，则，该工作进程的目标状态类型为瞬态类型。若各参数在时间进程内，不随时间变化而变化，则该工作进程的目标状态类型为稳态类型。
步骤203，根据各工作进程的目标状态类型，对各工作进程所包含的装置分别进行层级划分处理。
其中，瞬态类型的工作进程根据各参数的变化可将该工作进程划分为多个阶段，对于稳态类型的工作进程，由于各参数不随时间变化，因此，该进程无需细分。
请参考图3，其示出了本申请实施例提供的一种根据目标状态类型进行层级划分处理的流程示意图；根据各工作进程的目标状态类型，对各工作进程包含的多个装置分别进行层级划分处理，包括：
步骤301，对于该目标状态类型为瞬态类型的第一工作进程，采用进程划分工具对该第一工作进程进行阶段划分，得到多个现象发生阶段。
步骤302，对各现象发生阶段包含的多个装置分别进行层级划分处理。
其中，将目标状态类型为瞬态类型的工作进程记为第一工作进程，对于第一工作进程，根据进程划分工具，可将该第一工作进程划分为多个现象发生阶段，进而可以对各现象发生阶段所包含的装置进行层级划分。其中，进程划分工具中包含有时间进程内不同时间段对应的物理现象，根据不同时间段发生的不同物理现象，将该工作进程划分为多个现象发生阶段，例如，小破口事故进程可划分为：喷放阶段、自然循环阶段、环路水封与清除阶段、堆芯蒸发阶段、堆芯冷却剂恢复阶段；大破口事故进程可划分为：喷放阶段、再充水阶段、再淹没阶段。
终端可获取该进程划分工具，进而对各工作进程进行阶段划，其中，该进程划分工具可基于经过专家经验判断后的瞬态进程表进一步形成进程划分工具文件得到，请参考表1，其示出了本申请实施例提供的一种瞬态进程表，每一阶段划分经过专家确认且可根据专家经验的评论进行调整。根据调整后的瞬态进程表，可明确瞬态类型的工作进程如何划分，进而可以制作进程划分工具，从而对第一工作进程进行阶段划分，得到多个现象发生阶段。

表(1)
步骤303，对于该目标状态类型为稳态类型的第二工作进程，对该第二工作进程包含的多个装置分别进行层级划分处理。
其中，将目标状态类型为稳态类型的工作进程记为第二工作进程，对于第二工作进程，由于各参数不随时间变化，因此，该进程无需细分为多个现象发生阶段，因此，可直接对该工作进程所包含的装置进行层级划分。
本申请实施例中，根据各工作进程的目标状态类型对不同的工作进程进行不同的层级划分步骤，保证了对于参数随时间变化的瞬态类型的第一工作进程可根据现象发生阶段进行层级划分，实现有序的对各装置进行划分，为后续划分第一控制体提供基础，且提升第一控制体划分的效率，从而保证生成目标反应堆的建模数据的准确性、全面性以及高效性。
在一个实施例中，对于待进行物理现象识别的目标反应堆所涉及到的各工作进程所包含的装置分别进行层级划分处理，包括：根据系统、子系统、设备、组合件以及部件的层级关系，对各工作进程所包含的装置分别进行层级划分处理；其中，该层级关系为：系统层级包括的装置可划分为多个子系统层级，子系统层级包括的多个装置可划分为设备层级，设备层级包括的多个装置可划分为多个组合件层级，组合件层级包括的多个装置可划分为多个部件层级，部件层级中包括多个装置。
其中，层级关系从高到低为系统、子系统、设备、组合件、部件等不同层级，根据该层级关系，将各工作进程所包含的装置进行层级划分处理，具体地，对于第一工作进程，可对各现象发生阶段所包含的装置进行层级划分处理，例如，对于喷放现象发生阶段所包含的设备，总体划分为喷放系统，喷放系统所包含的各装置进一步可以划分为一回路系统、二回路系统、安全注入系统等子系统，对于一回路系统子系统可以分为反应堆压力容器及内构件、蒸汽发生器、主泵等设备，对于蒸汽发生器设备可以划分为管束组件、汽液分离器、下降段等组合件，对于汽液分离器组合件可以分为一级汽液分离器、重力分离器、干燥器等部件。对于第二工作进程，可直接将各装置进行层级划分处理。可选的，对于各工作进程的装置进行层级划分处理可根据实际需要进行划分，并非需每一层级都予以体现，例如，某一现象发生阶段的装置划分的最低层级可以为设备，而并非部件。根据层级划分结果，对最低层级的歌装置可进一步进行控制体划分。如图4所示，其示出了本申请实施例提供的一种层级划分示意图。
本申请实施例中，通过对各工作进程所包含的装置进行层级划分处理，实现目标反应堆的装置分解，可以保证目标反应堆中的所有组成装置均被全面覆盖分析。对于各装置按照系统、子系统、设备、组合件、部件等按照层级进行自上而下的划分，保证后续反应堆物理现象识别的全面性。
在一个实施例中，将该层级划分结果中最低层级所包含的装置进行控制体划分，包括：根据预先设定的控制体划分表，将该层级划分结果中最低层级所包含的装置进行控制体划分，其中，该控制体划分表中包含有该目标反应堆的设计建造信息。
其中，控制体划分表中包含有目标反应堆建造与涉及时的各装置的涉及参数和建造参数，即各装置的 设计建造信息，终端可根据预先设定的该控制体划分表，确定各装置的结构。因此，可根据该控制体划分表，对最低层级中所包含的各装置进行控制体划分，将结构相同的装置划分为同一制体，从而得到多个第一控制体。通过划分多个第一控制体，得到目标反应堆物理现象识别的最小分析单元，将复杂物理现象识别转化为单个分析单元的现象识别，实现了反应堆原型物理现象识别的由繁化简，保证物理现象识别的全面性和高效性。

步骤501，根据该物理现象识别表，对各第一控制体进行一致性分析；其中，该一致性分析包括：判断各控制体是否实现单一的物理现象。
