Nuclear Plant Care and Maintenance During the Retube Outage
Main Article Content
Abstract
The extended forced outage for reactor retubing of Pickering units 1 and 2 has prompted Ontario Hydro to implement a program, code named "Pick-up" (Pickering upgrading), to ensure, as far as possible, the satisfactory restart and subsequent
prolonged, safe and reliable operation of units 1 and 2, after retubing is complete. The program covers four areas: 1. plant lay-up, 2. extensive inspection of equipment and structures, 3. introduction of modifications and performance of
outstanding repairs, 4. recommissioning, to restart the systems and prove they are capable of supporting safe unit operation.
