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

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

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

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

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
