“…It is important to note that none of these include the DIF3D specific output tables. For REBUS, the focus will be to verify that the various DIF3D output tables are consistent with the expected results and consistent with the DIF3D verification itself [9]. To do this, the standalone DIF3D output tables based upon the time point data obtained from REBUS will be compared to the tables produced by DIF3D in the REBUS calculation at each time point.…”

“…The breakdown in identifying the critical engineering outputs of the REBUS software that must be verified starts by looking at which outputs from REBUS are being used by the analysts in the design process. The REBUS software is composed of several sub-modules, many of which are identical to those used by DIF3D itself and have already been verified [9]. Table 1 lists all of the sub-modules of REBUS with a summary of their purpose and a descriptor denoting whether the module is relevant for VTR and another descriptor ("Output") denoting whether the module produces module named identifiable output in either the main or auxiliary output.…”

“…The default set of radial sample points used by VARPEAK is plotted in Figure 5.2 and it should be quite apparent that the hexagonal evaluation (73) has more points than the Cartesian (25). This is because the testing done on Cartesian geometries is rather non-existent at this point and there was no need to refine it further.…”

The DIF3D-VARIANT solver is part of the DIF3D code which was developed at ANL for engineering level predictive analysis of nuclear reactor cores. Over the course of the last 20 years, the DIF3D-VARIANT option of DIF3D has become increasingly more used because of improvements in computer memory capabilities and performance. This is beneficial to the users of DIF3D as DIF3D-VARIANT is able to apply both p-and h-spatial mesh refinement strategies in diffusion and transport theory. Given its greater use, utility programs were created to assist in post-processing the DIF3D output. This document discusses the basic execution process of DIF3D and the output files it creates but is primarily focused on being the manual for the utility programs EvaluateFlux, VARPOW, VARPEAK, and DIF3DtoVTK.

“…That report is under review and when accepted, it will serve to define the set of verification work that needs to be done on RCT. A similar path was followed for the DIF3D software where its' requirements and verification tasks were established in [28]. In this section, only a summary of RCT and the verification work is provided.…”

The Fuels Irradiation and Physics Database (FIPD) is an ongoing DOE project on archival of the EBR-II metal-alloy fuel irradiation experiments. As part of its use in support of license applications, the Quality Assurance Program Plan (QAPP) was drafted and endorsed by NRC in an effort to demonstrate its compliance with regulatory expectations. Software Quality Assurance (SQA) for the physics portion of FIPD is intended to qualify the calculated quantities such as fuel and cladding temperatures, neutron fluence and axially varying burnup estimates for irradiated fuel elements. This report covers the initial evaluation of SQA status of three neutron physics and thermo-fluid codes (REBUS, RCT and SE2RCT) that form the basis of calculated quantities for as-irradiated characteristics of the tested metallic fuel elements. The report also introduces and SQA plan to address the identified deficiencies.
