“…Shift uses ORIGEN-6.2 as its burnup package [21]. Details of this coupling can be found in a previously published conference paper (reference [23]). Most of these problems have not been run through Shift as there are still a few features that need to be added to enable Shift to run them properly.…”

This documentation outlines the verification and validation of Shift for the Consortium for Advanced Simulation of Light Water Reactors (CASL). Five main types of problems were used for validation: small criticality benchmark problems; full-core reactor benchmarks for light water reactors; fixed source coupled neutron-photon dosimetry benchmarks; depletion/burnup benchmarks; and full-core reactor performance benchmarks. We compared Shift results to measured data and other simulated Monte Carlo radiation transport code results and found very good agreement in a variety of comparison measures. These include prediction of critical eigenvalue, radial and axial pin power distributions, rod worth, leakage spectra, and nuclide inventories over a burn cycle. Based on this validation of Shift, we are confident in Shift to provide reference results for CASL benchmarking.

“…Shift can model coupled neutron/photon physics, including secondary particles born both by collisions and fission. Shift is also fully coupled to automatic cross section generation capabilities in the SCALE code package, as well as to ORIGEN for nuclide depletion and decay [6]. Shift has previously been used for SNF cask dose analysis [7].…”

“…This maximizes the parallelism within a block while minimizing block-to-block communication. This depletion method has been shown to scale well to 10,000 cores [6]; however, since the depletion only constitutes a few percent (< 5) of the total simulation time, this performance is considered sufficient for the work proposed here.…”

This report reflects technical work which could support future decision making by the Department of Energy (DOE or Department). No inferences should be drawn from this report regarding future actions by DOE, which are limited both by the terms of the Standard Contract and a lack of Congressional appropriations for the Department to fulfill its obligations under the Nuclear Waste Policy Act including licensing and construction of a spent nuclear fuel repository.
