We present a method for solving Poisson and heat equations with discontinuous coefficients in two-and three-dimensions. It uses a Cartesian cutcell/embedded boundary method to represent the interface between materials, as described in Johansen & Colella (1998). Matching conditions across the interface are enforced using an approximation to fluxes at the boundary.Overall second order accuracy is achieved, as indicated by an array of tests using non-trivial interface geometries. Both the elliptic and heat solvers are shown to remain stable and efficient for material coefficient contrasts up to 10 6 , thanks in part to the use of geometric multigrid. A test of accuracy when adaptive mesh refinement capabilities are utilized is also performed.An example problem relevant to nuclear reactor core simulation is presented, demonstrating the ability of the method to solve problems with realistic physical parameters.

“…Correlations are used to determine the transport properties, surface tension, and saturation line. Fink and Leibowitz (1995) of Argonne National Laboratory (ANL) provided thermodynamic and transport properties of saturated sodium liquid and vapor between the melting and critical temperatures (371 -2504 K). They also estimated the uncertainty in various properties as a function of temperature.…”

“…However, the impact of the large deviations between the calculated and reported values is not expected to be significant in the analysis of the ABTR because the liquid phase is of primary interest. Fink and Leibowitz (1995) did not recommend values or uncertainties for the thermal conductivity and dynamic viscosity of saturated sodium vapor. The correlations used by RELAP5-3D to calculate these properties were based on fits to the values reported by Vargaftik (1975).…”

SUMMARYThe Actinide Burner Test Reactor (ABTR) is envisioned as a sodium-cooled, fast reactor that will burn the actinides generated in light water reactors to reduce nuclear waste and ease proliferation concerns. Thermal-hydraulic computer codes will have to be developed, verified, and validated to support the conceptual and final designs of the ABTR. The RELAP5-3D computer code is being considered as the thermal-hydraulic system code to support the development of the ABTR.An evaluation was performed to determine the applicability of RELAP5-3D for the analysis of a sodiumcooled fast reactor. The applicability evaluation consisted of several steps, including identifying the important transients and phenomena expected in the ABTR, identifying the models and correlations that affect the code's calculation of the important phenomena, and evaluating the applicability of the important models and correlations for calculating the important phenomena expected in the ABTR. The applicability evaluation identified code improvements and additional models needed to better simulate the ABTR. The accuracy of the sodium properties used by the code was also evaluated.The applicability evaluation generally showed that the existing models were adequate or that relatively minor changes were required to improve the code's representation of the important phenomena. However, new models are required to represent electromagnetic pumps and axial conduction in the fluid. Long-term improvements will also be needed to better represent the decay heat associated with the actinides burned by the reactor, the effects of thermal expansion of various core components on reactivity feedback, and the Reynolds-number dependence on the form loss coefficient for orifices. The evaluation of fluid properties indicated that the specific heat capacity of the liquid phase should be changed to better represent the values expected during normal operation and during transients.

“…The information on physical and thermodynamic properties of alkali metals is important in technological application of these groups of elements. Liquid alkali metals are widely used in modern science and technology, for example, in nuclear energy, emission electronics, new power-intensive chemical current sources, medicine, and other fields [2][3][4][5][6]. They are also used as coolant in nuclear power plants.…”
