Abstract : An investigation was made of the influence of fuel constituents on thermal stability during storage of Spec MIL-J-25656B type (JP-6) and other high temperature fuels. Modification of a 5-ml bomb test equipment and method showed promise of permitting precise measurement of labeled fuel components that contribute to deposits during thermal stressing. Three test methods were developed and evaluated for the separation and measurement of radioactivity contributed to deposits and gums by selected fuel constituents. One of these techniques used the principle of liquid-solid chromatography as the separation process followed by liquid scintillation counting of the radioactive reaction products. This method lacked sensitivity and resolution necessary for an acceptable test method. The other two test methods employed gas-liquid chromatography for separation and both ionization chamber counters and liquid scintillation radioassay techniques. An evaluation of these latter procedures showed the chromatographic separation procedures were adequate but quantitative recoveries of gum from the apparatus were dependent upon the radioisotope and fuel system. The migratory nature of tritium under conditions of severe thermal stress was investigated.
