Subject: T2 Cooling Package Resin Can Replaced 

The resin can was removed from the T2 cooling package and transported to the warm cell.  A replacement can with fresh resin was then installed.

A 12' sling and the standard four bridle was used to prevent the crane hook block from hitting the mezzanine railing on the south side.

The T2 package was started and inspected for leaks - none found.

 

Although T2 resin can replacement was scheduled for the 2015 shutdown, a decline in conductivity (with beam off) was observed since the cooling package was started in mid-march.
(See attached XSTRIP plot showing gradual decline and then increase after resin can swap)

The T2 resin can will now be scheduled for replacement every 2 years (rather than 3).  It is still unknown whether the T1 resin can will also need replacing every 2 years.
