(A-1) Provision of Codes & Manuals cont. Tsunami analysis tech. is transferred assuming users not familiar with tsunami analysis. As a user friendly package with all items shown in the flowchart below. Flowchart of the tsunami analysis (a) Preparation of topography data (b) Topography modeling (c) Tsunami source modeling (d) Numerical simulation 8
(A-1) Provision of Codes & Manuals cont. (a) Preparation of topography data ETOPO2 is prepared as default data of sea-depth and land level. ETOPO2 is the data around the world developed by NOAA. http://www.ngdc.noaa.gov/mgg/fliers/01mgg04.html 9
(A-1) Provision of Codes & Manuals cont. (b) Topography modeling TSUNAMI-Mesh is the GUI tool for mesh data generation of tsunami analysis code TSUNAMI developed by JNES. Usable data on TSUNAMI-Mesh is users proprietary topo. data. Selection of ana. region TSUNAMI-Mesh code Nested Grid and bathymetry allocation Fault model setup 10
(A-1) Provision of Codes & Manuals cont. (c) Tsunami source modeling TSUNAMI code is a wave propagation analysis code with GUI. Main function: Tsunami source modeling using Manshinha - Smylie (1971) method Far-field analysis with linear model Near-field analysis with linear and nonlinear model Run-up analysis Fault model TSUNAMI code Initial tsunami source North 11
(A-1) Provision of Codes & Manuals last (d) Numerical simulation TSUNAMI code is a wave propagation analysis code with GUI. Main function: Tsunami source modeling using Manshinha - Smylie (1971) method Far-field analysis with linear model Near-field analysis with linear and nonlinear model Run-up analysis TSUNAMI code Far-field analysis Near-field analysis Run-up analysis Japan Chile tsunami 12
(A-2) Implementation of training seminar JNES supported two training seminars. 1 st Training Seminar in Korea (25-26 June 2008) Operational training of TSUNAMI & TSUNAMI-Mesh Sample analysis in Users Manual (2004 Indian Ocean Tsunami) Dispatch of Code experts 13
(A-2) Implementation of training seminar cont. 2 nd Training Seminar in Turkey (25-27 March 2009) Suggestion of the participants work Benchmark analysis Site specific analysis in each countries Dispatch of Code experts 14
(A-3) Co-operative work with Participants transferred codes cont. AERB (India) & JNES Target : 2004 Indian Ocean Tsunami, Kalpakkam site Bathymetry Data : ETOPO2, GEBCO, Proprietary data Analysis : Far-field and Near-field, Run-up Mesh size : 5 min. or 6 min. (Far-field) 1350m ~ 50m (Near-field) AERB could use not only default but also Indian coast proprietary topo. data. Near-field TSUNAMI code was update through this work Analysis domain of far-field 15
(A-3) Co-operative work with Participants transferred codes cont. KEPRI (Korea) & JNES Target : 1983 Akita Tsunami, Ulchin site (Nihonkai Chubu Earthquake Tsunami) Bathymetry Data : ETOPO2, Proprietary data Analysis : Far-field and Near-field, Run-up Mesh size : 2 min (Far-field) 1100m ~ 4.6m (Near-field) KEPRI could use Korean coast proprietary topo. data. KEPRI could improve TSUNAMI source code in order to link with their familiar visualization code. New knowledge about the eddy viscosity was got through this work. Analysis domain of far-field 16

Tsunami Source Modeling Incorporated Administrative Agency Tsunami Analysis for Vietnam NPP Topography Modeling Open Topography Data (ETOPO2) Mesh Generator Code Manshinha and Smylie(1971) http://www.ngdc.noaa.gov/ mgg/fliers/01mgg04.html Tsunami Analysis Tsunami Analysis Code JNES provided Tsunami code to IAEA EBP project. If VARANS and VAEC join the project, they can get the data and codes. We recommend you to join IAEA New EBP and try Tsunami Analysis. 18
JNES had already NUCLEAR SAFETY SEMINAR at VIETNAM, March 2009 JNES hope meeting again in order to discuss NPP safety sitting 19
JNES Achievements 6. Summary Act.2 on IAEA Tsunami EBP had be implemented to share among MS tsunami analysis tech. and knowledge in relation to tsunami hazard assessment for nuclear power plant. In this EBP, JNES had aimed at helpful contributions based on the cooperative work with MS not the one-side contributions. JNES achieved our (A-1~3) agreements at Kick-off meeting and supported (B) benchmark analysis. (A-1) Provision of Codes & Manuals (A-2) Implementation of Training Seminar (A-3) Co-operative work with Participants transferred codes (B) Benchmark analysis JNES hope These transferred codes will take root at Member States of IAEA. These transferred codes will be used for the tsunami hazard assessment of nuclear power plants in future activities of IAEA or Member States. 20
