FAVOR/FAVPRO Update Patrick Raynaud Senior Materials Engineer RES/DE/REB

The Past: FAVOR-v16.1

• Developed and issued by ORNL late 2016

• Legacy Fortran

• FAVOR = FAVLOAD + FAVPFM + FAVPOST

- 3 executables

- Information passed via formatted text files

• Serial and sequential code

• SQA gaps

- ML20017A171

- ML20017A170 05/25/2022 NRC-Industry Meeting 2

FAVOR-v16.1 Software QA (SQA)

• Assessment of SQA documentation revealed gaps

- FAVOR was developed under ORNL SQA program, but documentation lost in time

• What we had:

- Small integration test suite: 27 cases with poor coverage

- Theory and User manuals

- Many reports on FAVOR documenting its use and benchmarking

• What was missing:

- SQA documentation

- Good descriptions of source code structure

- Source code version control 05/25/2022 NRC-Industry Meeting 3

Vision and Goals for FAVOR Modernization

• Completely refactor the code to create an equivalent tool written in modern Fortran

• GOALS

- Maintainability

- SQA and V&V improvements (testing and documentation)

- Modularity (make the code adaptable, enable easier feature addition)

- Object-oriented code

- Parallel code (performance improvements)

- Maximize automation for testing and documentation

- Merge the 3 sub-codes into 1 program: FAVPRO

- Use State-of-Practice tools and libraries

• GitHub: source control

• Fortran Package Manager (fpm): build and test automation

• Veggies/Garden: unit testing framework

• JSON: I/O 05/25/2022 NRC-Industry Meeting 4

From FAVOR-v16.1 to FAVOR-v20.1.12 (current release)

• CMake build system

• Source code improvements:

- Convert to free form.f90 files

- Modularization

- Begin removal of obsolete Fortran

• Testing improvements:

- New integration tests for better coverage (58 tests)

- A few unit tests

- Automatically run testing on GitHub for all code changes

• Documentation

- Automatically generate FORD developer documentation (detailed code descriptions with source parsing)

- Created new SQA documents:

• SQAP: ML21180A161

• CMMP: ML21180A167

• SRD: ML21246A230

• SDD: ML22132A068

- Created new Manuals:

• User Manual: ML21175A301

• Theory Manual: ML21175A300 05/25/2022 NRC-Industry Meeting 5

FAVOR-v20.1.12 to FAVPRO

• FAVPRO: Fracture Analysis of Vessels - PRObabilistic

• Current status:

- Partial JSON I/O implemented (ongoing)

- Full modularization complete

- Refactoring ongoing (bit by bit as needed / when it makes sense): goal is 100% in the next 18 months

- Move towards object-oriented functional programming

- Ongoing: merge the 3 sub-programs to reduce/remove intermediate I/O

- Parallelization is the last step (not yet started)

• Maximum leverage of Fortran Ecosystem 05/25/2022 NRC-Industry Meeting 6

FAVOR/FAVPRO User Group Update

• To obtain FAVOR and/or FAVPRO:

- Fill out the NRC Codes NDA

- Once approved, the code executables and input generator are downloaded via NRCs BOX service

• All approved users become members of the User Group

- Regular meetings (first meeting on 5/19/22-5/20/22), then short virtual updates (3-6 months), one longer meeting annually (format TBD)

- Newsletters

- New code versions

- User input to the development team is encouraged (bugs, new features, etc.)

• Cost: free!

- Could change at some point, but not in immediate future

• What about source code?

- Can be obtained on special case-by-case basis, pending approval of special request

• Send any FAVOR/FAVPRO questions to Patrick.Raynaud@nrc.gov 05/25/2022 NRC-Industry Meeting 7

Q&A Start of Backup Slides 05/25/2022 NRC-Industry Meeting 8

Leveraging the Modern Fortran Ecosystem

• Fortran has a growing user community and there is renewed interest in the language

• Fortran 2018 is a modern object-oriented parallel programming language

- High performance for scientific and engineering computations (one of the best)

• We use the following libraries

- fpm: Fortran Package Manager as the building and testing system

- Veggies/Garden for unit test development

- assert: assertion utility -> prerequisite checks

- quaff: quantities for Fortran -> unit tracking

- rojff: return of JSON for Fortran -> JSON interface

- erloff: errors and logging for Fortran

- iso_varying_string: implementation of Fortran ISO_VARYING_STRING

- Others 05/25/2022 NRC-Industry Meeting 9
