Project Aims

The main objective of the project was to perform a comprehensive analyses of the behaviour of hydrogen produced in severe accidents in VVER440/213, and investigate the possible measures against the threat of hydrogen burns or detonations in this specific type of containment. In particular, the project focus on:

• Development of hydrogen mitigation strategies for severe; accidents in VVER 440/213 containment;
• Transfer of know-how regarding hydrogen risk and mitigation techniques.

Project Results

The project was completed according to the Specified Terms of Reference and resulted in:

• Formulation of design bases and functional requirements;
• Performance of source term, mixing and distribution studies;
• Review of mitigation techniques;
• Evaluation of effectiveness of selected hydrogen control strategies;
• Specification of equipment, needed to threat of hydrogen burns or detonations;
• Development of hydrogen control severe accident guidelines;
• Cost assessment;
• Final report and recommendations.
