摘要： Provided is an integrated drawing producing method for common cause tracing. The integrated drawing producing method includes: distinguishing shapes of entities in at least one design drawing and assigning an attribute to each of distinguished entities; synthesizing the entities assigned the attributes in the at least one design drawing in units of a system where a common cause is to be traced; and generating an integrated drawing with a hierarchical structure by horizontally or vertically interconnecting the entities assigned the same attribute in the at least one design drawing.

摘要： Provided is a method of tracing a common cause failure in an integrated drawing. The method includes: synthesizing entities assigned attributes in at least one design drawing in units of a system where a common cause is to be traced; generating an integrated drawing with a hierarchical structure by horizontally or vertically interconnecting the entities assigned the same attribute in the at least one design drawing; and displaying a fault propagation path in the integrated drawing by using an internal tracer, wherein the displaying illustrates state information of the entities on the fault propagation path.

摘要： According to the disclosure, a position of a main control valve and a position of an auxiliary control valve are adjusted. In particular, a position of the auxiliary control valve is adjusted by determining whether a change in the position of the main control valve is in a preset deadband range, thereby preventing a periodic water level fluctuation of a steam generator.
