RESPONSE STRATEGY AND HIERARCHY OF WOL-SONG 2, 3, AND 4 NUCLEAR POWER PLANT ABNORMAL OPERATING MANUALS

摘要

Wolsong 2, 3, and 4 are CANDU 6 pressurized heavy water nuclear power plants, each with a gross electrical output of 715MW(e). The plants were constructed in the Republic of Korea during the 1990s. The three Wolsong units are based on the previous CANDU Wolsong Unit 1, declared in service in 1983. All four units are presently in commercial service. The Wolsong abnormal operating manuals were developed in a cooperative effort between Atomic Energy of Canada Limited, Korea Power Engineering Com- pany staff, and Korea Electric Power Corporation. The role of Atomic Energy of Canada Limited in performing risk assessment studies and supporting CANDU stations for the preparation of emergency operating procedures has greatly ben-efited the Wolsong abnormal operating manual program. Korea Electric Power Corporation provided training and supervision, Korea Power Engineering Company Inc. prepared the documentation, and Korea Electric Power Corporation reviewed the draft reports. The Wolsong 2. 3. and 4 abnormal operating manuals have been successfully prepared and converted to Emergency Operating Procedures. The validation of the Emergency Operating Procedures via a simulator, is presently in progress at Wolsong site. The paper describes scope, response strategy to upsets and the hierarchy of the abnormal operating manuals. In addition, the structure of abnormal operating manuals is described.
