Subject: Helium line damage, and hotcell window oil leaking 

Today myself and Adam Newsome started the leak detection steps for a target exchange and notice that the Helium line was not connected/broken from inside the hotcell.

A new line will need to be installed and the line attached to the helium wand.

This will need to be done when the target has been removed.

We will be installing a temporary line so that we can complete the target exchange first.

The temporary line will be put through the tool port as this seems the most practical and least likely to interfere with operations.

After will will have to schedule some time to install a permanent helium line with some newer flexible tubing. 

 

Also notice at the operator side that there is a small oil leak that appears to be coming from the hotcell window oil.

We have added an indicator(tape with pen marking) to the oil level to see how much we are loosing.

We will have to check the torques of the window bolts to ensure they are adequate.

If there is still an issue we may have to look at replacing the window seal.

 

Also Chad Fisher was consulted about the possible solutions
