Subject: MH Hot Cell Lab Manipulator Overhaul 

 Complete overhaul of all manipulators in the Remote Handling Hot Cell Lab in the Meson Hall was performed by Peter Dudley from Central Research Laboratories between October 28 - November 8th.  Overhaul included replacing all tapes and cables, disassembling, cleaning, lubricating, and rebuilding the master and slave wrist assemblies, adjusting motion locks, and other repairs/maintenance as required.  All 6 manipulator arms in the lab are now fully functional.  Pete reported that some cables from the manipulators in the west side hot cell were showing heavy wear, and cables from the other arms showed mild to moderate wear.

The highest amount of contamination was 1600cpm from a wet wipe on the inner slave boom on the west manipulator in the west hot cell.  Pete received a total dose of 0.10mSv as measured from DRDs worn during this period.

The temporary boot box area in the lab has been disassembled.  No contamination was found on the lab floor, tools, or manipulator removal cart.
