I undersand that the cost of the full set of four reactors is somewhere in the neighborhood of $5mil. They already have one reactor up and complete and many of the parts needed for the remaining are on site including the tubes. I don't know why the cost is so much. Pretty straight forward except for some specializing such as Chrome Welding. But $5mil can buy a lot of steel and chrome. Thomasson is doing pretty well here I believe. Someone else may have a clearer picture than me here so feel free to enlighten me. Ron
