Description

Quantitative margin benefits are assessed when a Digital Monitoring System (DMS) is installed to an operating Westinghouse type plant. Applied plant and cycle is Yonggwang Unit 1 Cycle 6. The referenced digital monitoring system is the COLSS (Core Operating Limit Supervisory System) of ABB-CE. The most limiting DNB prevention event of CEA Withdrawal is analyzed with the ABB-CE method. The results show that the DMS can bring around 7% more margins for both DNB and LOCA Fq standpoints of view. The DMS can also monitor the PCI limits
