1.0 BACKGROUND

Regqulatory Context:The Nuclear Regulatory Commission (NRC) relies on SCALE as a robust, state-of-the-artnuclear analysis computer code system that ensures independent review of licensee submittalsand accurate investigations of reactor and fuel phenomena important to nuclear safety.

This code affects all licensing evaluations that are being performed at the NRC that relies onindependent nuclear data libraries.

Technical Context:

SCALE currently contains three legacy Monte Carlo codes: KENO-V.a and KENO-VI forcriticality safety analysis (with limited depletion capabilities in TRITON) and Monaco for fixed-source neutron-gamma shielding analysis. The KENO codes can utilize SCALE multigroup orcontinuous-energy neutron cross sections. Monaco utilizes coupled neutron-gamma multigroupor continuous-energy cross sections. Each of these Monte Carlo capabilities was developed asan individual package to meet sponsor needs with unique features, and all are currently inproduction use by NRC staff. However, all SCALE Monte Carlo capabilities are built on thelegacy framework of KENO, which dates back to the 1 960s. This framework creates challengesfor integrating new features, upgrading the codes for parallel operation, or performing rigorousunit testing to quantify the performance of each component inside the code.

Under two recent internal ORNL Laboratory Directed Research and Development (LDRD)projects, a new modern parallel Monte Carlo code called Shift has been developed within abroader radiation transport infrastructure at ORNL. The outcome of these efforts is a robustparallel Monte Carlo framework that provides an unprecedented opportunity to implementSCALE Monte Carlo calculations on cutting edge~hardware, ranging from desktop PCs to Linuxclusters to supercomputers. The modular design of Shift makes it possible, in futuredevelopment, to provide a variety of geometry and physics packages for users to create theirmodels and perform analysis, all within the single Shift package.

2.0 OBJECTIVE

The objective of the Task Order is twofold: (1) integrate the massively parallel Monte Carloapplication, Shift, into standard SCALE sequenceS; (2) verify and validate Shift for application toreactor analysis ahd criticality safety problems through this front-end interface. The resultingMonte Carlo capability will enable NRC staff to perform high fidelity, continuous-energy MonteCarlo simulations for analysis of steady-state core neutronics, fuel burnup, and criticality safetyapplications.

3.0 SCOPE OF WORK

The DOE Laboratory must provide all resources necessary to accomplish the tasks and

deliverables described in this statement of work (SOW).

In this work the well-known physics and user input and output features of SCALE Monte Carlocapabilities will be updated and consolidated into Shift to provide a unified Monte Carlo code(replacing KENO and Monaco) that is modern, easier to maintain and update, and operates inparallel. Shift =uses the Atlas geometry package developed for the Polaris lattice physics code

(V6449, T0004) that enables simplified user input, especially for the definition of regions inrepeated structures to facilitate use of Monte Carlo depletion, and operates more efficientlyusing modern geometry algorithms.

Integration of Shift into SCALE for reactor physics, criticality safety, and fixed source shieldinganalyses will provide NRC users with.a single easy-to-use robust modern Monte Carlo code thatwill run efficiently on parallel computing platforms (PCs and Linux clusters). This will reduceSCALE maintenance costs by removing three legacy codes from SCALE. It will provide newcapabilities for NRC users that are not available in SCALE and could not be implemented in thecurrent legacy Monte Carlo codes.

4.0 SPECIFIC TASKS

The DOE Laboratory must perform the following tasks:

Task 1: Integrate Shift, into SCALE sequences

SCALE provides common mechanisms for defining geometries, materials, and runtimeparameters for existing Monte Carlo reactor analysis and criticality sequences. Shift has beenbuilt to utilize these same mechanics; however, it uses a different front-end for high-performance, parallel execution. This task will fully integrate Shift so that it can be executedthrough SCALE non-depletion sequences for criticality safety and reactor physics analyses.

A set of standard CSAS features that will be supported by Shift has already been defined. At thecompletion of this task order a complete report will be produced indicating the full set of featuresavailable through the Shift non-depletion sequences. Capabilities that need to be developed or

completed are listed below.

o The new SCALE geometry package Atlas inl Shift needs to be verified for support of allKENO geometrical features. Atlas improvements are needed for tracking particles inarrays; adding missing KENO-Vl geometry types; and speedup of particle tracking,

,, Starting source distribution: KENO starting source distributions need to be implementedin Shift.

,,Output processing - Shift's output currently requires a Python post processor. Aconvenient method to generate output and update content for SCALE is needed.

o Visualization of shift results in SCALE's Fulcrum module will require update toread/process the HDF5 files from Shift.

The subtasks involved in this effort are:

* Convert SCALE input into XML format specified by Shifto Inline Shift front-end library to read XML from SCALE inputo Specify standard set of defaults for Shift operationo Improve Atlas geometry capabilities and speedo Add output processing and visualization for Shift in SCALE

Deliverables:

a Integrated SCALE sequences using Shift* Updated SCALE user manual with Shift input/output features

Task 2: Validation and Verification of Shift sequences

The SCALE code system contains a large set of validation problems in its VALID benchmarksuite. At the completion of Task 1, we will execute the VALID suite using Shift as the underlyingMonte Carlo application. The objective of this task is to validate the Shift sequences for use inreactor physics and criticality safety applications. Comparisons will be made to KENO forconsistency of results, memory usage, and execution time.

Deliverables:

Letter report documenting Shift performance and results on SCALE validation suite

Task 3: Shift Hybrid and Advanced Capabilities for Reactor Physics and Criticality Safety

Shift is built in the Exnihilo framework that contains the Denovo deterministic transport solvers.For optimal execution Monte Carlo methods require forward and/or adjoint deterministic fluxcalculations. For example, the existing Sourcerer method in SCALE uses a deterministicDenovo SN calculation toiestimate the initial fission source distribution for KENO. Thesecapabilities need to be integrated into Shift.

The subtasks for this effort are as follows:

o Integration of Denovo SN and SPN for initial fission source distributions in Shifto Integration of a fission matrix tally and acceleration method for criticality safety problems

(this feature has been prototyped in a version Of the Shift Monte Carlo kernel)* Validation and tuning of these capabilities using the SCALE test suite

Deliverables:

* Fission matrix and Sourcerer capabilities in Shift

,,Letter report documenting performance and capabilities of new methods

Task 4: ShiftIORIGEN Depletion Implementation and Validation

Shift is integrated with ORIGEN for depletion and activation analysis. However, this capabilityneeds to be implemented in a SCALE depletion sequence. This capability will require significantvalidation. The objective of this task is to validate the depletion capability in Shift on a suite ofproblems to be defined. Both measured data and code-to-code comparisons will be

investigated. Initial code-to-code comparisons have been performed between Serpent, VESTA,and Shift. This task will also include analysis of code performance.

Deliverables:

o Letter report documenting performance and accuracy of Shift depletion and activation for

core neutronics and criticality safety.
