Phase 3 – PHT Drain & Dry, Cut & Cap, Moderator Drain & Dry

Crews will drain and dry the Moderator and Primary Heat Transport (PHT) systems. These are the last key milestones before the major component replacement begins.

PHT Drain and Dry will be performed in parallel with the bulkheads installation. Moderator Drain and Dry will follow PHT drying and will overlap with beginning of feeder removal.
