4 Objectives of Project on Non-Electric Applications To increase the capability of MS interested in deploying nuclear demonstration projects, to perform economic evaluations of integrated systems, and to establish experience on such applications. To enhance information exchange, cooperative assessments and collaborative research among Member States interested in non-electric applications. Outcome: Provide MSs with information, compiled by the Agency, on such applications such as nuclear desalination and on means of safely and economically coupling the production systems with nuclear reactors

13 Main Advantages of Cogeneration for Nonelectric Applications Harnessing waste heat from NPPs Better economics: Due to the cogeneration itself Use of shared resources Use of off-peak power Mutual benefits: (electricity vs. high quality of water) Improvement of overall thermal efficiency

14 Harnessing waste heat Case of PBMR for desalination Waste heat: Heat extracted from NPP with no penalty to the power production Using reject heat from the pre-cooler and intercooler of PBMR = 220 MWth at 70 C + MED desalination technology Desalinated water m3/day Cover the needs of people Waste heat can also be recovered from PWR and CANDU type reactors to preheat RO seawater desalination

15 HTGR for Hydrogen production H2 production: 60 Mton/yr worldwide (9 Mton/yr in US) Ammonia production Extraction/Upgrading of Oil Sands and heavy crude Synthetic fuels (methanol, synthetic diesel / gasoline) For transportation: 28% of US energy is used for transportation Essential for overall CO 2 reduction Projected Outputs from a 600 MWth HTGR

16 Hydrogen production during off-peak power Conventional Electrolysis (> 1000 kg/day) Dedicated nuclear HT Steam Electrolysis plant Off-peak grid electricity ($0.05/kW hr), HTSE Large-scale Steam Methane Reforming $/kg 4.15 $3.23 $2.50 $ directly dependent on the cost of natural gas, no carbon tax 16

17 HTGR For Oil Sand Production INL Case Study: 3000 MW HTGR Facility - Supports recovery of 150,000 barrels/day (SAGD) - Provides the energy (electricity and hydrogen ) needs for upgrading to produce 145,000 bpd of premium synthetic crude - Reduces natural gas consumption by 205 MSCFD - Reduces CO2 emissions by 13 kton/day ~15% increase in hydrogen yield for nuclear-assisted case

18 HTGR For oil shale and ammonia production
