|
TCS cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate. New re-routed
system is tested to 70KV without spark. No leak has been found on new lines after the test.
ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane |

|
Field measurements were taken of the old source trays. The old TM#2 source tray had a minimum field value of 0.50 mSv/hr and a maximum of 1.18
mSv/hr through 360 deg of rotation. The box was rotated around three times and put back in the vault. TM#1 old source tray was also removed and measured
as well the field values for it were a minimum of 0.52 mSv/hr and a maximum of 1.15 mSv/hr through 360 deg of rotation. The box was rotated around three |

|
Pete Dudley, manipulator service technician from CRL, was on site from Nov 27-30 to service the NHC Model N manipulators (See E-log entry #1578 for background).
He began by evaluating the motion selection and electric drive of the manipulator installed on the blue service cart. This manipulator had
chip A0166R01, same as the right side manipulator which had the failure described in E-Log 1578. Pete noted that the arm was very slow to switch |
