RE: [Vo]:Re: Kamacite and natural fractionation of heavy nickelJones-- Your argument about Zn volatility has some merit. However, from the data it would appear that the Zn in the “before reaction” laser activation test migrated to the cooler parts of the reactor and were not measured in the “after reaction” laser activation test. This is the opposite of what I think you are suggesting..

From: Bob Cook If I am not wrong, the laser activation indicates Zn is 0.004 mass % vs the suggested 4%—more than an order of magnitude LOW!—more like 3 orders Low! I checked the table of mass % and it adds to 100 percent. From: Eric Walker I do not think there was any report of very much Zn in the fuel. If there was Zn-64 in the samples tested it was not apparent from the report. In fact as I noted yesterday, Zn was on the order of .01 percent. It was not anyway reported near 4 % per my review of the AP report translated by Higgins. . As I attempted to show, even though the total amount of zinc reported in the ICP-MS analysis was small, it was of an order of magnitude to potentially explain part of the mass 64 balance. Eric
