4.         NATURE OF PROBLEM SOLVED

SCALE is a comprehensive modeling and simulation suite for nuclear safety analysis and design that is developed and maintained by Oak Ridge National Laboratory under contract with the U.S. Nuclear Regulatory Commission, U.S. Department of Energy, and the National Nuclear Security Administration. The code suite is used to perform reactor physics, criticality safety, radiation shielding, and spent fuel characterization for nuclear facilities and transportation/storage package designs.

5.         METHOD OF SOLUTION

The SCALE system consists of easy-to-use analytical sequences, which are automated through control modules, to perform the necessary data processing and manipulation of well-established computer codes, referred to as functional modules. Computations with SCALE are typically characterized by the type of analysis to be performed (e.g., criticality, shielding, or lattice physics) and the geometric complexity of the system being analyzed. The user then prepares a single set of input descriptors in terms of easily visualized engineering parameters specified in a simplified, free-form format. The analytical sequence is defined by this single input specification. The SCALE control modules use this information to derive additional parameters and prepare input for each of the functional modules necessary to compute the quantities of interest that can utilize multiple radiation transport codes that employ discrete ordinates, Monte Carlo, or hybrid methods.

6.         RESTRICTIONS OR LIMITATIONS

Modeling assumptions that limit or restrict the usefulness or accuracy of the individual module are discussed in SCALE 6.3 User Manual.

7.         TYPICAL RUNNING TIME

Running times are problem dependent and depend greatly on the sequence used and the cross-section library selected. They range from less than one minute for a simple 1D criticality or depletion/decay problem to several hours for a complex 3D shielding or sensitivity/uncertainty analysis or 3D Monte Carlo depletion case. Runtimes for sample problems vary from approximately 12 hours to 24 hours depending on the speed of the machine.
