Project Aims
This project was design for study of behaviour of the bubble condenser system of VVER 440/213 units for the confinement of radioactive releases following design basis accidents. Project objectives were as follows:

  • In depth experimental study of the structural behaviour of the pressure retaining boundary of the bubble condenser;

  • Testing of the thermohydraulic behaviour of the bubble condenser system on a test section which could replicate in full size the original configuration portion of the bubble condeser floor and which model the relevant adjacent systems.

Project Results

  • Development of adequate information for assessment by the Safety authorities of the Beneficiary countries for test methodologies, test campaigns, and open the representativeness of the result and conlusions obtained;

  • Development and implementation of two test programmes;

  • T/H and fluid -structure interaction test on a test prototype typical for Paks NPP;

  • Structural verification tests on a test prototype typical for Dukovany/Bohunice NPP;

  • Building of respective testing facilities;

  • Perfomance of the qualification tests;

  • Comparison of the test and analysis results;

  • Elaboration of conclusions.

Further Project Results
Further information on the project results could be obtained from the beneficiary organisation.
