It is stated in one of the CANDU PHWR safety reports that in the 1970s and 1980s, some pressure tubes were removed from Pickering Units 3 and 4 and Bruce Unit 2 because of leakage at through-wall DHC cracks in rolled joints that had high residual stresses. Can you please provide evidence that this information was provided to the Commission members and the public during relicensing hearings for the respective plants. Can you also please provide data, internal and external reports, internal and external correspondence on all pressure tubes that were prematurely removed from service from all CANDU PHWRs, both in Canada and overseas. Please also provide criteria that were used to remove pressure tubes from service prior to retubing. Please also include crack and deformation data on pressure tubes that were noted to have smaller cracks but were not removed from service.Organization: Canadian Nuclear Safety Commission
