Abstract: This publication presents the main results of the Technical Meeting on Application of Advanced Safety Methods (for licensing of Nuclear Power Plants) held on 7-11 June 2010 in Bled, Slovenia. It was organized with the cooperation of the International Atomic Energy Agency (IAEA) and with the Organization for Economic Co-operation and Development - Nuclear Energy Agency (OECD/NEA). This meeting is part of a series organized by the three organizations and has the objective to provide a forum to exchange information regarding activity in the use of Advanced Safety Methods more specifically focussing on deterministic Best Estimate plus Uncertainty (BEPU) methods both in the domains of research and relative to licensing and on Probabilistic Safety Analysis. The use of BEPU methods is possible today due to the increased knowledge in Thermal-hydraulic phenomena and high performance computational tools and allows a much clearer understanding of the available safety margin during Design Base Accidents. The results shows that the industry is in fact moving in this direction in order to be able to demonstrate compliance to safety limits after power uprates as the older conservative methods were shown to be too pessimistic. The use of probabilistic and deterministic methods is today starting to be used for defence in depth concept and also more often in combination with Deterministic Safety Analysis.
