Broken tong cable on SW manipulator (serial #8106) of SHC was replaced today.

Following ISAC Hot Cell entry procedure, Document 157554, SHC was entered and wrist and tong cable were replaced with a pre-run/assembled wrist, cable and tong. It is standard to try and pre-make/load a new cable into a spare tong assembly to reduce time spent in the HC. This marks the first time a wrist has been replaced. Rationale for replacing the wrist at this time is that internal spacer A-14118 which the ting cable rides over has had grooves worn into it. This is a result of regular wear and tear but could be causing premature wear on the tong cable. Replacement is a preventative measure. This is the original wrist and spacer from the original install in 1998. The wrist that was removed will be rebuilt and swapped out with the original one on the SE manipulator (serial #7986) at a later date.

Parts replaced today are: New - Bottom half of wrist joint (CRL-13950), New - Tong cable (CRL-14230) and used tong assembly (CRL-18062)

Procedure took about 40 minutes. Dose received was ~0.046 uSv
