向运行中的动力反应堆注入的化学品注入系统和化学品输送过程/方法
摘要：
本发明涉及向运行中的动力反应堆进行注入的化学品注入系统和化学品输送过程/方法。本发明公开了注入系统10，其设计用于在动力反应堆正常运行条件期间通过给水系统开关22向反应堆输送化学溶液。该输送过程经由正排量泵12和14。化学品注入是以浓缩溶液形式，在从滑道排出前该浓缩溶液由系统10在内部稀释。注入系统10使由于在运输管线15上沉积造成的化学品损耗最小，使得较高浓度溶液能被用作注入剂，消除了化学稀释的费时繁重过程，将化学溶液提高到注入所需的压力，通过使用冲洗溶液防止在注射泵头部处从溶液沉淀出来固体，并且在动力反应堆启动、关闭和运行过程中形成的新裂缝表面上沉积新鲜化学品。
摘要（英）：

An injection system 10 designed to deliver a chemical solution into a reactor through feedwater system taps 22 during normal operating condition of a power reactor is disclosed. The process of delivery is via positive displacement pumps 12 and 14. Injection of chemical is in a concentrated solution form, which is internally diluted by the system 10 prior to discharging from the skid. The injection system 10 minimizes chemical loss due to deposition on the transit line 15, enables a higher concentrated solution to be used as the injectant, eliminates the time consuming laborious process of chemical dilution, raises chemical solution to the pressure required for injection, prevents solid precipitations out of solution at the injection pump head through the use of a flush solution, and deposits fresh chemical on new crack surfaces that develop during a power reactor start-up, shutdown and operation.
