THERFAT Résumé de rapport

Project ID: FIKS-CT-2001-00158
Financé au titre de: FP5-EAECTP C

Collation and synthesis of field experience

As a first step in the THERFAT project, a survey of fatigue susceptible Tee-configuration with hot and cold temperature mixing in various nuclear power plants has been carried out by the utilities E.ON, EDF and Fortum. From these a variety of Tee-geometries were selected to be investigated (DN 50/DN 50, DN 100/DN 25, DN 80/ DN 80) with different flow velocities and temperature differences.

A reduced number of configuration is selected as the starting point for the upcoming activities in the project: performance of representative experiments, visualization and quantification of relevant parameters, verification of experimental results by numerical calculation, development of a numerical evaluation approach applicable for Tee-configurations, determination of existing safety margins using common codes procedures, determination of load bearing capabilities, comparison of results, combination of the results and development of an overall integrity concept framework.
