Thats correct LT and also the Oak Ridge National Laboratories is the most likely location for testing graphite in reactors for the department of energy since this is the site of one of the first graphite moderated nuclear reactors and the source of most of the studies made by DOE on graphite use, characteristics and reactor moderation.

Most likely carried out in Dr. Burchell's IFEL (Irradiated Fuels Examination Laboratory) at ONRL. Based on the fact that ONRL presentations have indicated that ZEN is a supplier of material to ONRL, it seems likely that this type of study may be underway and may have been underway for some time in addition to the battery studies.

The following note on a research paper from ORNL would seem to indicate they are actively carrying out this research and that each sample of natural or even sythetic graphite may act differently depending on its physical characteristics and the location of the source. This bodes well for ZEN's Albany deposit IMO.
