I think we may be talking about two different liabilities. The liability that AECL in Canada retains is principally for the Chalk River and the Whiteshell sites. Those sites have several hundred buildings, of which, during the 60 years, some were internally contaminated. One of the missions that we will see in the next 10 years is to remove and take down 120 buildings.
What Canada and Chalk River are doing at Chalk River is building a highly designed facility to move that material into for long-term disposal for that type of material. That material would not be required to be placed into a deep geological depository. It will be what we call a near-surface disposal facility, which we're engaging in with CNSC—actually, the licencee is engaging with CNSC.
