The report covers the second years work on an investigation of the influence of fuel constituents on thermal stability during storage of Spec MIL-J-25656B type JP-6 and other high temperature fuels. Ninety-four test blends representing 12 fuels and 9 radioactive fuel components were prepared, tested and stored at 130F in the evaluation of a microscale thermal stability procedure developed for the purpose of determining the contribution of selected fuel components to thermally induced deposits. Sixty-four of these test blends reached 26 weeks storage interval and were retested to determine the effect of storage upon deposit-forming tendencies. A study of several variables associated with a dynamic microhydrogenation method using tritium as the index of reactivity was completed. Final investigations with a series of test fuels and pure hydrocarbons concluded the application of the technique. An alternate static system of hydrogenation utilizing active metal catalysts prepared by the in situ treatment of the metal salt with sodium borohydride, and the in situ generation of hydrogen from sodium borohydride was completed. A revised procedure employing tritium labeled borohydride was likewise developed and evaluated. Author
