Abstract

The EU RTD activities in the field of nuclear fission safety (1994-98) included a cluster of projects known as INNO composed of 11 projects (seven shared-cost and four concerted actions) in which 35 different organizations, representing research centres, universities, regulators, utilities and vendors from seven EU Member States and Switzerland were involved. These projects included both experimental and analytical activities directed mainly to study the phenomena (both form the core region and the containment building) and for safety measures (e.g. depressurisation, injection), as well as to demonstrate their feasibility for different types of advanced light water reactor (LWR) designs.

The experiments have been performed in some of the most important European thermal-hydraulic facilities in Europe covering large-scale integral (e.g. PANDA, PACTEL), large-scale separate-effect (e.g. NOKO), and small-scale separate-effect (e.g. LINX, EPICE, SUCOT, MUCON, STORM, AIDA, PECA) tests. The research undertaken has contributed to demonstrate the feasibility and the efficiency of most of the passive systems being investigated for several types of advanced LWRs, in particular the ESBWR and the SWR1000 designs. They have also provided a valuable independent bank of experimental data about different phenomena and aspects ready to be used by reactor designers and code developers. In particular, the following aspects have been thoroughly assessed:

-Efficiency of pool-immersed heat exchangers operating at low pressure (projects IPSS, BWRCA, POOLTHY and TEPSS).
-Efficiency of condensers with various geometrical tube arrangements for different steam/gas mixtures (projects IPSS, BWRCA, INCON, CONGA and POOLTHY).
-Performance of gravity-driven safety injection systems (APSI project).
-Performance of single-stage steam injector systems (SYNTHESIS project).
-Deposit of aerosols in the inside and outside surfaces of heat exchange tubes (projects TEPSS and CONGA). CONGA).
