秦山核电二期工程卸压箱的设计

Design of Relief Tank for Qinshan Phase ⅡNuclear Power Project

卸压箱是反应堆冷却剂系统的专用设备。它主要用于接收并冷凝、冷却来自稳压器安全阀或释放阀排入的高温高压蒸汽， 同时也接收来自各系统的疏水。本文介绍了秦山核电二期工程卸压箱的设计。该设备的设计特点是： 选材合理、蒸汽冷凝充分、设备集冷凝冷却于一体、爆破片装置接管兼作人孔之用。该设备经有关专家审查并验收合格， 同意用于秦山核电二期工程。

The relief tank is the special equipment of the reactor coolant system The purpose of this equipment is to collect,condensate and cool steam of the high temperature and the high pressure from the pressurizer safety valve or the relief valve and collect drain water from various systems This paper briefly introduces the design of the relief tank for the Qinshan Phase Ⅱnuclear power project The design features of equipment are following:the material is selected reasonably,the steam is condensated completely both condensating and cooling are done inside the equipment,the bursting disc device nozzle have the function of the man hole The design of this equipment is rational,which is examined by the experts The proprietor has agreed to use this equipment for the Qinshan Phase Ⅱnuclear power project
