7 Computational Methods Validation and Benchmark PMB Status of PMB The Computational Method Validation and Benchmark PMB (provisional) focuses on ensuring the numerical models used for reactor system analysis Members have convened since February Draft Project Plan was prepared. Methods calculation envelope should encompass system envelope Participants: China, Euratom, (France), Japan, Korea, South Africa, United States China started participation from May France ceased cooperation in this PMB. 7

8 Status of the Computational Methods Validation and Benchmark Provisional PMB PMB Activities in 2010: 10 th provisional PMB held at Tsinghua University, Beijing, China on May Draft Project Plan revised due to new Chinese contributions, now under review for signature of Project Arrangement. Issues regarding Project Arrangement: The hold of PMBR project (South Africa) caused delay, because PBMR was supposed to lead 3 Work Packages and to participate in several Tasks. Decision about the future direction of WP pending. Euratom ended RAPHAEL (April 2010) and continues with ARCHER (start February 2011). 8

9 Project Plan for the Computational Methods Validation and Benchmark PMB Project Plan Project Plan covers and beyond Project Plan was revised: WP for Mechanics, HTTR, Chinese contributions added), currently under review; Work Packages WP 1: Phenomena Identification and Ranking Table (PIRT) Methodology WP 2: Computational Fluid Dynamics WP 3: Reactor Core Physics and Nuclear Data WP 4: Chemistry & Transport WP 5: Reactor and Plant Dynamics WP 6: Mechanics WP 7: HTTR tests 9

PBMR had already contributed heavily to PMB by sharing a large number of deliverables (upload to Gen IV Materials Handbook) PBMR representative no longer available, withdrawal required (Section 16.2 of PA). Discussions with remaining PBMR staff ongoing to safeguard PBMR knowhow (cooperation with universities, NECSA etc. through e.g. IAEA projects) 10
