The Decision
OPG Management recommended that the restart of
Units 2 and 3 not proceed, based on return on
investment analysis. Decision endorsed by Board
of Directors and Provincial Government. This
decision is final.

• Environmental Assessment
• Site Acceptance
• Construction
• Commissioning
• Operation
• Safe Storage
• Dismantling
• Site Restoration

Safe Storage Stage

• Overall principles have been identified
• Both reactors will be defuelled.
• Heavy water will be removed from the moderator
  and heat transport systems.
• Systems will be de-activated (where possible).
• Common systems supporting Units 1 and 4 will be
  moved to a live unit (where possible).

Strategy

• System end states have been developed for each of
  the 53 groups of systems identified for system
  performance monitoring.
• End states are being documented and approved in a
  Safe Storage Package, which will include
• Flowsheets
• Controlled document lists
• Master equipment lists
• Power supply lists
• Air supply lists
• Active TCR
• Applicable predefined

Licensing Issues

• The CNSC has approved reactor defuelling and
  removal of heavy water under the existing
  operating license.
• At sometime in the future after the fuel and
  heavy water have been removed, the license may
  again be modified to reflect the safe storage
  conditions.
