7/24/011 TFTR D&D Status July 24, 2001
2
7/24/012 Project Status The TFTR D&D Project will be completed on time and within budget
3
7/24/013 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
7/24/014 Project Status cont 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
7/24/015 Project Status cont Engineering cont : A sector disassembly fixture has been designed, fabricated and tested - a second fixture is currently in fabrication
6
7/24/016 Project Status cont 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
7/24/017 Project Status cont 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
7/24/018 Project Status cont 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
7/24/019 Project Status cont 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
7/24/0110 Project Status cont 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
7/24/0111 Project Status cont Diamond Wire Cutting Engineering cont :
12
7/24/0112 Project Status cont Field Work: Vacuum Pumping Ducts have been removed
13
7/24/0113 Project Status cont Field Work cont : Lintels and columns and Shear Compression Panels have been removed
14
7/24/0114 Project Status cont Field Work cont : Ducts connecting Neutral Beamlines to the vacuum vessel have been removed
15
7/24/0115 Project Status cont Field Work cont : Vacuum vessel appendages have been removed and all windows have been reinforced
16
7/24/0116 Project Status cont Field Work cont : Vacuum vessel has been filled with lightweight concrete
17
7/24/0117 Project Status cont The TFTR D&D Project is continuing on a path which will assure that it will be completed on time and within budget
