Original Toronto Star caption: No taxpayer gripes are likely over the cost of a building (right) that isn't expected to do its own thing more than once in every 500,000 years. The energy-containment tower is accident insurance at the Pickering nuclear power station. It holds suspended a huge concrete tank containing, more than 2,000,000 gallons of water.
