Canadian CO2 production
Most CO2 doesn’t come from our electricity production
And anyway our electricity is already pretty clean
We don’t make much difference

Conclusions
We need solutions that are
1. Global
2. Address power and building heat and process heat and transport needs
3. Work at a community level

THTR 1986-1989 300MWe
The fuel produced by the pilot plant will be used by the demonstration high-temperature gas-cooled reactor plant being built at Shidaowan, near Weihai city in Shandong province. This will initially comprise twin HTR-PM reactor modules driving a single 210 MWe steam turbine. Construction started in late 2012, with commercial operation scheduled in 2015. A further 18 such HTR-PM units are proposed at Shidaowan

‘Alfa’ Class Submarines
– 7 submarines in the class, with 155 MW(th) LBE cooled reactors
– Operated from 1972
– “The fastest class of military submarines ever built”
– LBE reactor technology was operationally employed in an extremely demanding application beginning nearly 40 years ago

developed
Factory in place and
production started
Multiple Units in
operation
How do we sign enough orders simultaneously to get through the tunnel
