Tritium results Reanalysis of Trap Rock, Algonquin, Gypsum Attached are the subject sample reanalysis. All 3 sample results were less that LLD.

These sample results represent a new aliquot of each sample from the original container that was distilled and counted in a new sample vial.

The original results for these samples, which were reported as positive activity (>LLD), are considered to be the result of contamination on the tritium analyzer sample holder rack. Additional testing and evaluation is in progress to confirm the contamination and documentation will be provided for your review. The racks have been removed from service and immediate short term corrective actions were set in place to prevent future contamination issues.

The contamination of these samples will be documented in a JAF Condition Report (CR) that I will forward to you as soon as the CR is entered.

Sample status: Currently in the tritium counter are the three original vials followed by the 4 samples received on 02/02/06. These samples will be done counting on Saturday night and the results will be processed and forwarded to you on Monday AM (02/06/06).

I will be at VY next week attending Entergy training. I will be in contact with the lab on a regular basis and will provide you with a channel of communication once I set up at VY.
