Description

Add an ACTINV code target and the initial FNS iron decay-heat configuration for
the 1996 five-minute irradiation, including all 20 measured cooling times.
JADE selects explicit activation and decay files, generates the scalar JSON
input, runs ACTINV locally, validates the output and compares calculated and
measured heat in its workbook and atlas. Experimental errors are retained.

The initial scope is neutron activation of one material with an inline
709-group spectrum. ACTINV and nuclear data are installed separately. The GUI
uses a shared code-name mapping, and ACTINV setup and execution guidance follow
the existing documentation layout.

The JADE-ready inputs and measurements are proposed in
IAEA-NDS/open-benchmarks#26.
The benchmark documentation points to that repository rather than requiring
manual input formatting. The data PR must be merged before JADE's standard
IAEA download can install this case. Users select an ACTINV library explicitly
in the default benchmark entry.

Validation

  • A fresh Python 3.13.14 installation with pip install -e '.[dev,ui]' selected
    F4Enix 1.1.0 and passed 256 offline tests, with 16 OpenMC skips and
    1 deselected installation test. Remote fetch tests were excluded.
  • Checked the hosted case against the original CoNDERC archive: all 709 spectrum
    groups, all 20 measurements, relative errors and exact cooling endpoints.
    JADE installed the prepared data and generated an input accepted by ACTINV's
    strict schema validation. Synthetic output verified all 20 C/E points, heat
    conversion, error propagation, workbook and plotted atlas generation.
  • An earlier real CLI integration reproduced the ACTINV iron reference through
    raw processing, workbook and atlas. The latest hosting checks did not repeat
    a solver calculation.
  • Sphinx builds retain the same 54 existing diagnostic messages. Ruff adds
    no diagnostic signatures; the repository retains 97 existing findings.

Upstream GitHub CI is awaiting maintainer approval. OpenMC and interactive GUI
testing remain outside the local checks above.

Type of change

  • New feature: inventory-code target and initial benchmark configuration.

Checklist

  • Added adapter and configuration regression tests.
  • Added user and benchmark documentation and raw/Excel/atlas configuration.
  • Prepared the IAEA input and measurement PR with CoNDERC attribution.
  • Addressed the maintainer's requested code and documentation changes.
  • Complete upstream CI and independent maintainer review.
  • Confirm the final change introduces no new warnings in upstream CI.

Summary by CodeRabbit

  • New Features

    • Added support for running deterministic ACTINV activation calculations locally, including library selection and processing decay-heat and activity results.
    • Added the FNS iron decay-heat benchmark, with cooling-time comparisons and plotting configurations.
    • Added a cooling-time option for viewing tally results relative to the end of irradiation.
  • Documentation

    • Expanded guidance for ACTINV setup, supported settings, library configuration, result interpretation, and the FNS benchmark.

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

Merge Risk: 🔵 Low · up to 6dda7

This adds a local ACTINV adapter and the FNS decay-heat benchmark. The code appears self-contained. The benchmark can only be installed through JADE's download once the separate data PR is merged, so confirm that before or shortly after merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 6dda7

ACTINV runs only after a user configures the executable and data library. Input, execution, and result checks limit the new integration’s exposure, but the separately installed solver and externally supplied benchmark inputs leave some uncertainty.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The new execution boundary is the configured local solver process, with the filesystem authority of the JADE user; no separate tenant or service authority is evidenced. The shipped settings do not launch it without explicit executable and library configuration.

Trust Boundaries and Controls

  • observed — Downloaded benchmark templates can supply scalar calculation data, while configured files supply authoritative library and decay paths. The runner uses a fixed argument vector without shell execution and validates solver output before publication.

Resilience and Maintainability Implications

  • observed — The runner removes any previous completion marker before execution, stages output temporarily, and writes the marker only after result and schedule validation. The success checker requires both result and marker files.

Hardening Proposals

  • proposed — If downloaded templates are treated as untrusted, verify the complete solver-input schema at this boundary and consider least-privilege execution. JADE currently forwards fields beyond its explicit checks; the external solver’s handling of them was not available to assess.

I’m a rabbit with a cooling-time chart,
I hop through each second, precise from the start.
ACTINV brings heat and activity to view,
FNS gains a benchmark, its tables do too.
I nibble my notes, then bound through the hay.

Do we need this? I see that this check is run anyway before every actinv run (which I think it is the place where the check should live). Also, a check done here will always throw an error when actinv is not configured in the environment (which will not be the default for most users)

Agreed, the runner is the better place for this. I've removed the application check and kept validation in SingleRunACTINV.run.

Drive the run configuration GUI from a single code-name mapping, including
library selection and YAML round-tripping.

Keep ACTINV execution validation in its runner and apply the input-only
executable rule consistently across codes.

Move ACTINV guidance into the existing documentation sections, document
cooling_time, and place the FNS benchmark entry alongside the other FNS cases.
Cover the GUI refactor and execution/continuation behaviour with regression
tests.

Thanks for the review. I've addressed the comments in fc12859. The local suite passed 256 tests using F4Enix 0.19.0, with 16 OpenMC skips and download tests excluded. The docs build adds no new warnings. Could you take another look?

Thanks! I think we are almost there. With regards to the open points:

Open points for review

  1. Is ignoring nps and using Error=0 for absent Monte Carlo sampling error
    appropriate for this deterministic target? Experimental errors remain in C/E.

Yes ignoring NPS is perfectly fine in this case and I would say the same for the error=0. In case we get issues due divisions by zero somewhere we can address it later.

  1. Is local execution suitable initially? ACTINV rejects MPI, prefixes and job
    modes. These settings are session-wide, limiting mixed-code sessions;
    input-only generation remains supported.

For activation codes I guess running on cluster is much less important so I agree on the limitation. I am not too worried
about having the settings valid for the entire session as it is not common to run JADE for all codes and all benchmarks at the same time.

  1. Should the CoNDERC-derived inputs follow the IAEA open-benchmarks hosting
    route, and what attribution or permissions are required? No source data are
    included here. ACTINV's repository already contains the derived spectrum and
    20 measured values with a source citation; redistribution terms remain to be
    confirmed.

I think we should follow indeed the same IAEA open benchmarks route. There is already a disclaimer there that some other benchmarks have been taken from CoNDERC, this would be just another one.

Please add a PR there with the inputs already in JADE format and then remove the part of the documentation added in JADE about how to format this benchmark inputs.
Consider that both CoNDERC and IAEA open benchmarks are both owned by the IAEA.

After this we should have it!

Update the hosting text to match the agreed IAEA Open Benchmarks route.

The reviewer asked for three changes. Submit the inputs to IAEA Open Benchmarks in JADE format. Remove the JADE documentation about formatting the benchmark inputs. Stop describing the hosting as pending maintainer agreement. This section still describes pending hosting and gives manual layout and formatting instructions. When the IAEA PR lands, replace this section with a reference to the fetched inputs.

I've updated the branch with the F4Enix 1.x changes from developing. A fresh install with F4Enix 1.1.0 passes 256 offline tests. Could you approve the new CI run? I'll prepare the IAEA benchmark PR next.

The inputs and measurements are in IAEA-NDS/open-benchmarks#26. I've removed the manual formatting instructions and linked the hosted files in bc8a9d4. All seven benchmark quality tests pass locally, and the docs build adds no new warnings. JADE's download will pick up the files once that PR is merged.
