LESSON LEARNED TRITIUM ANALYSIS IN THE HOT LAB

Description:

Originator: LEANNE K BIRKMIRE Supv Contacted: Jhansi Kandasamy Condition

Description:

On 04/29/09 tritium samples were taken for support of the tritium ACMP..

One of these sample had known tritium activity. When the samples were distilled the sample with known tritium activity was distilled first after a blank for cleanliness verification. After the sample with known tritium activity was run it contaminated the sample that was run after it.

Immediate actions taken:

The samples were distilled again with a blank and then the samples were run. The samples were distilled from the least amount of tritium based on previous results to the highest amount of tritium based on previous results and then a blank was run to verify cleanliness of the distillation after all samples were complete.

Recommended Actions:

Samples were re-run and results were consistent with what was expected and previous results. Technician involved was briefed on the logistic of sequencing analysis.

Coaching was provided to technicians and participants in tritium analysis from other sites that sample prep distillations should be performed starting with sampels with lowest activity, absed on previous results, to http://eamgenco.ceco.com/cap/servlet/ReportARServlet 6/23/2009
