Development of an expert system for success path generation and operator`s action guides in NPP: Verification and validation of COSMOS

Technical Report:

Abstract

For the support of emergency operation, an expert system named COSMOS (COmputerized Success-path MOnitoring System) is being developed at Korea Atomic Energy Research Institute (KAERI). COSMOS identifies the critical safety function`s (CSF`S) status, and suggests the overall response strategy with a set of success paths which restore the challenged CSF`s. The status of CSF is identified by the rule-based reasoning. The overall response strategy is inferred according to the identified CSF`s status. The success paths are generated by the given structure descriptions of systems and the general generation algorithm. For efficient man-machine interface, a colar graphic display is utilized. COSMOS is being built on a workstation. The major tasks to build an expert system such as COSMOS are the construction of knowledge base and inference engine. In COSMOS, the knowledges are derived from the Emergency Operating Procedures (EOPs), and the forward chaining is adopted as the inference strategy. While the knowledge base and inference engine are the most common and essential elements of an expert system, they are not the only ones. The evaluation of expert systems can not only lessen the risk of using faulty software, but also enhance the acceptability of the expert systems by both users and  More>>

The evaluation of expert systems can not only lessen the risk of using faulty software, but also enhance the acceptability of the expert systems by both users and regulators. The evaluation of expert systems consists of the system verification, validation and user acceptance testing. Among them, in this report, we have focused our attention to verification and validation (V{approx_equal}V) of expert systems. We have accessed the general V{approx_equal}V procedures and tried to develop the specific V{approx_equal}V procedure for COSMOS. (Author).}
