Phase 2 – Bulkhead and shielding install

Protective shielding and 16 bulkheads are installed to isolate Unit 6 from the operating units. By installing the shielding, workers can remain in the vault when the Fueling Machine Trolley performs spent fuel runs, which generally occurs one time every 24 hour.

Once the bulkheads are installed, vault pressure testing is completed to ensure Unit 6 has been fully isolated from the three remaining operating units.

16 bulkheads; 7.2 tons each
