Development of the Qualified Plant Nodalization for Safety and Operational Transient Analysis
The objective of the activity described in this paper was to develop "frozen and qualified" nodalization of the NPP Krško (NEK) for the large thermohydraulic code. A procedure to developed qualified nodalization for the safety analysis, as well for the operational transients has been introduced. Nodalization development and qualification process tightly involved NPP Krško personnel, in order to develop plant nodalization suitable for the operational use, and to assure that the model will present up-to-date plant. The experience gained in the use of the large thermohydraulic codes identified three basic conditions that should be fulfilled for the correct use of the large thermohydraulic codes: - Used code should be frozen and qualified through international assessment program; - Developer of the nodalization should be qualified to the use of the chosen code; - Nodalization of the plant should be properly qualified. .Qualified plant nodalization has been developed in three stages: 1. Build-up of the qualified plant data base; 2. Development of the plant nodalization, or so called base input deck; 3. Qualification of the nodalization.
