This phase began with four days of calandria vessel inspection. During this time, a camera is inserted and remotely controlled to allow viewing of key areas, such as high-stress welds, reactivity mechanisms and moderator nozzles.
“The only time we can look at these key features of the calandria vessel is after the fuel channels and other components have been removed, so this can only happen now,” said Mike Allen, Senior Vice President, Nuclear Refurbishment.
This is followed by inspection and reconditioning of a number of components. Then, the rebuilding of the reactor begins with installation of calandria tubes, fuel channel assemblies, and lower feeders.
“After years of planning, we’re excited to move forward with rebuilding this reactor, so it can provide Ontarians with an additional 30 years of clean, reliable, affordable power,” Allen said.
