CAT Chat Minutes

March 24, 2003

 

Information and Follow-up

Paul Zschack said he had a situation at 34ID last week with kinematic mounts under critical components (white beam mask) in FOE.  There is a potential shifting of component position due to unequal vacuum pressures.  The component should be labeled individually as a critical component and the unequal pressure issue addressed.  Did anyone else have this problem?

Roger replied that this was an APS responsibility and hell look into the problem.

Shipments of Radioactive Material & Foreign Soil B. Glagola:  Bruce explained that DOE has stopped all radioactive material shipments.  If you are expecting a shipment, and it is in process, you should have no problem receiving it but will not be able to send back.  If you have any questions, please contact Bruce at 2-9797.

USDA is requiring special permit to allow foreign soil brought into ANL.  Bruce is in the process of obtaining a permit for APS to allow foreign soil in/out of ANL.  Below is Bruces presentation and explanation on this USDA procedure:
