•
•
Schedule: October 1999 through September 2002
Original Estimated Project Cost: $40.3M
Projected Project Cost at Completion: $36.8M
Objectives:
– Remove activated and/or contaminated components from
the TFTR Test Cell, Test Cell Basement and Tritium Area.
(Tritium Area later changed to mothball)
– Provide data for the decommissioning of future fusion
projects.

Overview of TFTR D&D cont
• Not a typical decontamination and decommissioning
(D&D) project
• Will not be returned to “green field” conditions
• Facility will not be released for unrestricted use
• Not a capital project - funded with operating money

Management of TFTR D&D Project
• Used existing PPPL Project Control Systems (PCS)
• Cost - Performance Measurement System employed
utilizing earned value techniques
• Schedule - PC based “Primavera” System
• Management Meetings / Project Reports

Conduct of Operations
•
•
•
•
•
•
Worker safety highest priority
Protecting environment from tritium release
Different set of hazards than TFTR operations
Centralized control of work activities
Procedure compliance mandatory
Clear responsibility and accountability

Work Package Process cont
• Work Control Center
» Review Engineering Package for completeness
» Ensure prerequisites are completed prior to issuing
package for work
» Arrange for all permits
» Release work package to field per schedule
» Arrange for resolution of field problems
» Return completed work package to Engineering for
drawing update/voiding
