I guess my point is that there are no commercial PBNRs running at this time, maybe some small experimental ones and even the Chinese who seem to have the biggest ambitions in this area are not planning to start their first commerical reactor till 2017 and then it will be a small 200+MW reactor only. I just think it will take at least 10 years or more before PBNR start to appear in any quantity and that as a customer target for ZEN it is really not important. So working to product graphite which meets the specs for the nuclear industry is IMHO a waste of time at this point in time.
