TFTR D&D Status July 24, 2001

1. TFTR D&D Status July 24, 2001

2. Project Status The TFTR D&D Project will be completed on time and within budget

3. Project Status Reviews since 12/00: • DOE Cost and Schedule Review, 12/00 • PPPL Audit of D&D Project, 12/00 - 1/01 - no findings • DOE-PG Unified Safety Review, 4/01 - no findings • DOE-CH Review of Sector Lift Procedure, 5/01 - approved • ALARA Review of Vessel Segmentation, 5/01 - approved • DOE EH-24 Review, 5/01 - awaiting report

4. Project Statuscont Engineering: • Vessel Segmentation FMEA approved • Successful Final Design Review for Vessel Segmentation • Last of the removal procedures are being prepared • Temporary vessel supports, for vessel segmentation, have been designed, fabricated, tested, and are currently being installed

5. Project Statuscont Engineering cont: • A sector disassembly fixture has been designed, fabricated and tested - a second fixture is currently in fabrication

6. Project Statuscont Engineering cont: • A special vertical bandsaw has been tested and procured for cutting the TF coils in half to reduce the cost of shipping them for burial • Contamination barriers for the annulus between the vacuum vessel and the TF coils have been designed, tested, and are currently being installed

7. Project Statuscont Engineering cont: • Continuing to spend more time on engineering (especially Diamond Wire Cutting) because it improves overall safety and efficiency • Continuing to pay attention to the principles of Integrated Safety Management

8. Project Statuscont Diamond Wire Cutting Engineering: • Cutting of the vacuum vessel will be done using a diamond wire rope technology that has been specifically developed for this purpose - reduced airborne contamination - reduced worker exposure - reduced cost

9. Project Statuscont Diamond Wire Cutting Engineering cont: • When each vessel segment is removed, two TF coils will be lifted with it • A disassembly fixture will be used to support the vessel segment while the TF coils are rotated off of it • The vessel segments will be placed in special shipping/burial containers and immediately shipped • A special vertical bandsaw will be used to cut the TF coils in half to reduce the cost of shipping them for burial

10. Project Statuscont Diamond Wire Cutting Engineering cont: • Diamond Wire Cutting trials have developed the process into a mature state • Results indicate that we can do a through-cut in a day • Process has been refined to reduce the chance of a broken wire and reduce worker exposure should a wire need to be replaced • Process for gas cooling/cleaning of the wire has been developed to reduce tritium contaminated waste

11. Project Statuscont Diamond Wire Cutting Engineering cont:

12. Project Statuscont Field Work: Vacuum Pumping Ducts have been removed

13. Project Statuscont Field Work cont: Lintels and columns and Shear Compression Panels have been removed

14. Project Statuscont Field Work cont: Ducts connecting Neutral Beamlines to the vacuum vessel have been removed

15. Project Statuscont Field Work cont: Vacuum vessel appendages have been removed and all windows have been reinforced

16. Project Statuscont Field Work cont: Vacuum vessel has been filled with lightweight concrete

17. Project Statuscont The TFTR D&D Project is continuing on a path which will assure that it will be completed on time and within budget
