| Abstract: | The recent interest in the development of proliferation resistant fuel cycles has prompted an investigation of the gas core reactor concept. The gas core reactor consists of a cavity containing fissile material in a gaseous state surrounded by an external reflector-moderator. A fuel-coolant mixture of UF/sub 6/ and Helium is considered in most gas-core reactor conceptual designs. Currently this concept is one of several being considered for the Non-proliferation Alternate Systems Assessment Program (NASAP). Since the gas core reactor is seen to present special difficulties with respect to reactor physics analysis, the INEL gas core critical benchmark offered an ideal test of reactor physics methods. The experiment was analyzed with Monte Carlo, S/sub n/ transport theory and diffusion theory methods. Diffusion theory methods are shown to be inadequate for the gas core concept. More importantly, it is shown that a high order scattering approximation is necessary to accurately predict experimental results, regardless of method. Convergence was found to be particularly sensitive to the selection of acceleration strategies and parameters. |
