Overview of TFTR D&D

• 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

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

June 25-26, 2002 D&D Lessons Learned Workshop 12

Work Package Process• Engineering

» Define work scope

» Conduct Peer Reviews and Design Reviews

» Prepare installation/removal procedure

» Define prerequisites for field work

» Update or void drawings after removal is complete

June 25-26, 2002 D&D Lessons Learned Workshop 13

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

June 25-26, 2002 D&D Lessons Learned Workshop 14

Work Package Process cont

• Construction» Verify and/or perform safing / lockout/tagout per

PPPL procedures as required

» Perform field work per procedure

» Return completed work package to Work Control Center
