1982 ANNUAL STATUS REPORT - PLUTONIUM FUELS AND ACTINIDE PROGRAMME
An important step forward has been achieved in the studies of the Equation of State of Nuclear Fuels up to 5000 K. The discrepancy which had existed between theory and experiment in the vapour pressure over liquid UO-2 has now been explained. Formation of some of the less abundant isotopes in PWR fuel has been determined experimentally for the first time and the first irradiation of a fuel containing equal proportions of uranium and americium has been examined giving important results required for the design of future experiments. Aerosol formation during the fabrication of plutonium containing fuels, part of the activity "Safe Handling of Plutonium Fuel" has been studied using different sampling and analysis techniques. Characteristics of the aerosols generated using alternative fuel fabrication procedures have been compared. The protactinium-hydrogen system has been studied for the first time and an important confirmation by UPSXPS of the localization of 5f electrons in americium metal and their itineracy in plutonium has been obtained.
