A Study on Improvement of AsBuilt Deliverables Transfer Process for Nuclear Power Plant Operations & Maintenance Plant engineering is carried out in planning, engineering, procurement, construction, operation u0026 maintenance (Ou0026M) processes. A large number of deliverables are generated at each stage. These deliverables are submitted as asbuilt deliverables during the transition from Engineering, Procurement and Construction (EPC) stage to Ou0026M stage. Once the asbuilt deliverables are verified, they are handed(turned) over to the Ou0026M phase. South Korea is one of the first countries that managed the configuration of its nuclear power plants. However, an issue has been raised with the possibility of data loss, resulting from the lack of data interconnectivity in the information system for configuration management. In order to address this issue, it is necessary to trace the configuration information between varied asbuilt deliverables. In this study, we reviewed the traceability to improve the safety and reliability for the Ou0026M of nuclear power plants. In particular, we propose a new process that improves the traceability between asbuilt drawings, the most important part of asbuilt deliverables, through a practical example.

Demonstration of a conformity assessment data model The purpose of this research was to test the applicability of our conformity assessment data model using a simple industrial conformity example and an industrial software tool. As a demonstration case, we stated a claim relating to diversity of a nuclear fuel cooling pool control system. With the Siemensxe2x80x99 Polarionxe2x84xa2 Application Lifecycle Management tool, we traced the claim to the diversity requirement, to the system model and to the dependency analysis result, which was used as the evidence for the claim. We managed to implement all the artefacts to be traced according to our data model into the industrial tool. We found out that it is rather straightforward to implement our conformity assessment data model in a software tool offering databaseoriented repository and traceability support. The data model is thus suggested for industrial use to make the conformity assessment process more effective by providing traceability information, structured input and storage of compliance data and by facilitating automatic document generation.
