APROS modelling of containment pressure suppression systems (TIFANY). TIFANY summary report

This report summarizes the research and development activities performed in the TIFANY project during 2003 and 2004 through October. The aim of the project is to improve the capabilities of the APROS simulation program to serve as an integrated thermal hydraulic code for design basis accidents for different types of pressurized and boiling water reactors. In this report, the objectives and results of the project are described up to date. The TIFANY project involves National Technology Agency of Finland, Fortum and Teollisuuden Voima as financing organizations, and Fortum Nuclear Services and VTT Processes as working organizations.
