Plant life management at Ontario Hydro

The Ontario Hydro Nuclear Aging Management Team is developing an aging management program designed to anticipate, detect and mitigate potential degradation before it has any serious adverse effect on plant safety, reliability or economic viability. Only a small number of components have a major effect on long-term reliability, but the decision as to which they are is necessarily subjective if not based on experience. Identifying and evaluating all potential degradation mechanisms requires a complete review of the operating and maintenance history, of all inspections conducted, and of international experience. 2 figs
