Title: Subgroup Benchmark Calculations for the Intra-Pellet Nonuniform Temperature Cases

Abstract

A benchmark suite has been developed by Seoul National University (SNU) for intrapellet nonuniform temperature distribution cases based on the practical temperature profiles according to the thermal power levels. Though a new subgroup capability for nonuniform temperature distribution was implemented in MPACT, no validation calculation has been performed for the new capability. This study focuses on bench-marking the new capability through a code-to-code comparison. Two continuous-energy Monte Carlo codes, McCARD and CE-KENO, are engaged in obtaining reference solutions, and the MPACT results are compared to the SNU nTRACER using a similar cross section library and subgroup method to obtain self-shielded cross sections.

  • A study was conducted to evaluate the capabilities of different numerical methods used to represent microstructure behavior at the mesoscale for irradiated material using an idealized benchmark problem. The purpose of the mesoscale benchmark problem was to provide a common basis to assess several mesoscale methods with the objective of identifying the strengths and areas of improvement in the predictive modeling of microstructure evolution. In this work, mesoscale models (phase-field, Potts, and kinetic Monte Carlo) developed by PNNL, INL, SNL, and ORNL were used to calculate the evolution kinetics of intra-granular fission gas bubbles in UO2 fuel under post-irradiation thermalmore » annealing conditions. The benchmark problem was constructed to include important microstructural evolution mechanisms on the kinetics of intra-granular fission gas bubble behavior such as the atomic diffusion of Xe atoms, U vacancies, and O vacancies, the effect of vacancy capture and emission from defects, and the elastic interaction of non-equilibrium gas bubbles. An idealized set of assumptions was imposed on the benchmark problem to simplify the mechanisms considered. The capability and numerical efficiency of different models are compared against selected experimental and simulation results. These comparisons find that the phase-field methods, by the nature of the free energy formulation, are able to represent a larger subset of the mechanisms influencing the intra-granular bubble growth and coarsening mechanisms in the idealized benchmark problem as compared to the Potts and kinetic Monte Carlo methods. It is recognized that the mesoscale benchmark problem as formulated does not specifically highlight the strengths of the discrete particle modeling used in the Potts and kinetic Monte Carlo methods. Future efforts are recommended to construct increasingly more complex mesoscale benchmark problems to further verify and validate the predictive capabilities of the mesoscale modeling methods used in this study.« less
  • In actual reactors employing uranium in the form of plates it is necessary to use additional stnactural support material which leads to a nonuniform lattice array of subassemblies or clusters. The thin resonance theory of Stein for an infinite array of fuel plates moderated by water was extended to handle nonuniform arrays of fuel plates, or for that matter any resonance absorber including control rods, typical of that likely to be found in an actual reactor. (W.D.M.)
  • Three memorandums are included that cover the following subject areas: (1) implications of elementary hydrodynamics, (2) comparative neutron yields estimated according to elementary (self-similar) hydrodynamics - solid fuel shells versus gas fuel, and (3) possible athermal effects on neutron yield. (MOW)
  • Materials properties and procedures are presented for use in conjunction with the CYGRO5 computer program which calculates the performance of fuel rods. Agreement between calculated and measured diameter and length changes of test fuel rods containing duplex fuel pellets is demonstrated. A Zircaloy fast flux growth correlation for 51% coldworked cladding is also presented.
  • Performance calculations have been completed for 17 cases that examine the sensitivity of the heat rates from combustion island concept power generation systems to various changes in the process configuration. A combustion island is loosely defined as a combined-cycle system that uses either dry or slurried coal for direct firing in a gas turbine. In this concept, slagging off-base combustors and sorbent injection are being considered as possible modifications to conventional oil-fired gas turbine systems. The purpose of this Technical Note is to define feasible system configurations. No systems economics have been included. All cases discussed in this Technical Notemore » were based on an approximately 100 MW combined-cycle power plant, which consisted of one gas turbine that produced approximately 75 MW of power (General Electric Frame 7 size range), and a steam turbine bottoming cycle. The major results from this study are: (1) The heat rate is reduced by approximately 400 Btu/kWhr by changing from a coal water fuel (CWF) feed wtih a 60% coal concentration to a dry feed. (2) Thermodynamic calculations show system performance is relatively insensitive to coal ash content. (3) Each 1% change in pressure loss through the gas turbine combustion section (i.e., the section between the compressor exit and turbine inlet) changes the system heat rate by approximately 33 Btu/kWhr. Conventional gas turbines typically have approximately a 4% pressure loss through the combustion section. Sorbent injection will have a relatively small effect on system performance, provided the combustion section pressure drop remains the same. 4 refs., 9 figs., 8 tabs.« less
