Robert Pak 22 DOE VTX Review June 2, 2009 Cooling F - Ion Extraction Test Report 10/21/2008 Dele Fayemi 3M Electronics Markets Materials Division Tel: (651) Summary Samples of 3M Novec 7000 and 7200 subjected to neutron irradiation received from Los Alamos National Laboratory were tested to determine if degradation had occurred. Decomposition was quantified through fluoride ion measurements as described in the 3M test method: “ Fluoride ion extraction – indication of thermal decomposition ”. The irradiated fluid samples showed slightly elevated, but insignificant fluoride ion levels when compared to control samples. Test Results The results of the test are given in table 1. Table 1 Interpretation The in-beam samples recorded average free fluoride ion concentration of ~0.03 ppm. Though these are elevated fluoride ion levels compared to the virgin samples, these concentrations are much less than 1 ppm and indicate insignificant degradation beam 6.7x10 11 N eq /cm 2 integrated dose from LANSCE Cooling Fluid has no problem from irradiation
