5 Some observation made : 1. Propagation of the modern industrialization in northern hemisphere going west with time flow... Europe + Russia -> N-America->Japan->Korea ->China (+South East Asia) -> India -> Middle East 2. We created speedy CO2 production system using high speed computers, could not stop or slow down due to Globally linked economy 3. And this system is also growing rapidly in volume (IN, CN, SE Asia) mostly based on a mix of Carbon Fuel + IT Economy results the Speedy ice melting, ocean temperature and sea level rise, climate change For our sustainability speedy deployment of counter measure is required High density non-carbon energy resource -> Nuclear Energy 5

6 atmosphere for FTR 6

7 ITER Project launched ITER is a joint international research and development project (7BUSD const in 10yrs + 20yrs ops + 5yrs decommissioning) that aims to demonstrate the scientific and technical feasibility of fusion power. Q > 5-10, sec to steady-state operation The partners in the project - the ITER Parties - are EU(represented by EURATOM), Japan, China, India, Korea, Russia and US ITER construction started in

11 FTR characteristics 11

12 Noble idea-fusion-fission Hybrid Reactor from 60 s till NOW continued recommendation from world nuclear, fusion leader s Originator and successors 79 Hans Albrecht Bethe ( ) 1967 Nobel Prizer Jeff Freidberg author of Ideal MHD 08 Paul-Henri Rebut JET (Joint European Torus) Director ITER CDA Director 12

13 Selection of Materials for Nuclear Reactor Structures 13

14 Humbleness maintained! FTR does use Existing or Near-term developed Technology and Material in Fission and Fusion - Structure material, divertor heat load, TBR maintained from fission - Proven plasma operation mode - Q < 5, low thermal fusion power - pulsed mode operation, less cost for heating, diagnostics, power supply - subcritical fission reaction - passive safety - use established fission and fusion nuclear technology Bridging commercially available fission technology to remote fusion energy commercialization 14

15 CDA -> EDA Plasma volume Blanket volume Magnet volume (cold mass volume) Fuel cycle (fusion + fission) Material (structural, PFC) Ancillary system Interface volume Assembly + Maintenance system Safety + containment Duty cycle + availability Pumping + vacuum volume Heat removal + cooling system BOP Costing * blue: for Hybrid, black: via ITER r&d activity 15

18 implementation consideration and plan 18

19 Consideration for FTR implementation 1. Technically feasible? Can be built to an industrial grade? What quantitative advantage over other technical competitor? R&D -> Engr. -> manufacturing within time, A system is ready? 2. Who will use? Who will buy? 3. How urgent? When it could/should be done? Any priority setting is made? 4. How much does it cost? Use public money or private? How financing could be done? 5. Who will approve? Any implementation law available/international Framework available? Under what framework could it be implemented? 19

20 Timing consideration 2010 CDA to EDA starts 2020 ITER in operation DEATH valley start 2030 Full commercial Grade FTR operation Fusion Usefulness DEMO completion 2017 US Obama Administration ended FTR pilot plant in operation And verification start 20

21 Time to check a readiness for FTR implementation Check fusion side details/readiness Check fission side/readiness Check interface development/readiness Check for detailed planning Establish step by step process 21
