Analysis of the Number of Axial Node and Functional Design Verification of the DNBR Module for an Advanced Reactor Core Protection System

Creators

Description

The objective of this project is to determine an optimal number of axial node for the on-line calculation of DNBR in an advanced localized RCOPS and perform the design modifications associated with the DNBR module update. The constraints on the number of axial node were removed by changing thr PLC platform for RCOPS. In addition, it was also found that fewer number of axial node would decrease the DNBR accuracy. Hence the RCOPS DNBR module is modified to increase the number of axial node greater than 20. This study performs the DNBR uncertainty analysis and predicts the DNBR margin depending on the number of axial node. The functional design of the RCOPS DNBR module is revised and the functional design revision is verified. The RCOPS database is also revised to accommodate the modification the functional design
