Friday, January 27, 2017, 08:44, chad fisher, South Hot-Cell, Standard Operation, TM2, Ta#50, UCx #18 - Ta Feibiad Dummy installed. Target Change Waterline interference 
|
On Tuesday, January 24th UCx#18 was removed from TM2 and Ta febiad dummy installed. I encountered the same issue mounting the new target as last time.
Was able to determine that the issue is the routing of the waterlines to the right-hand (as viewed from the operator) high current tube heater. The lines
interfer the the target mounting plate (bottom right hand corner). |
