I seem to have mucked something up on the conversion from the evil arhaic units used to quantify natural gas and the power outputs a nuclear plant would need to replace them. I blame the American engineers that came up with mcf to represent a thousand cubic feet of natural gas. I blame them for the British Thermal Unit too, just because.
The actual conversion numbers are:
1 mcf = 1.027 Mbtu = 1.083 GJ (thermal) = 301 kWh (thermal)
Since current tar sands production is around one million barrels a day, consuming according to the Syncrude corporate reports 1.35 mcf/bbl, then the actual energy consumption is equivalent to a 12,540 MW continious thermal output.
This isn't the danty little 100 MW reactor I was talking about. It's more like 4 mondo 900 MW CANDU reactors -- something on the scale of Pickering, Ontario. Since production is expected to increase to 5 million barrels a day by 2025, we would be able to build a significant number of full-size reactors in Fort McMurray, regardless of in-situ production versus mining and upgrading issues.
