CPR1000型核电站核岛冷水机组在电站特殊工况下的改造措施

Discussion on CPR1000 nuclear island refrigeration unit's special using conditions

核电站核岛通风空调系统在电站运行中有着重要作用,核岛制冷机作为空调冷源供给设备作用尤为重要。由于核电站核岛空调系统特殊运行条件,导致核岛制冷机运行工况极端恶劣。本文重点研究分析了核岛制冷机在冷却水极端低温和高温运行工况确保正常运行的应对措施。

It is well known that as the equipment providing chilled water for air-conditioning systems the refrigeration units plays an important role in nuclear power plant. Some special operation conditions of the air-conditioning systems bring forward rigorous operation requirements for the refrigeration units and this article emphasis upon studying the solutions for extreme low cooling water temperature and high environment temperature for refrigeration units operation.
