Flantier-Nuclear-Reglementation-1

A specialized vision-language model optimized for nuclear regulatory document analysis and retrieval.

Overview

Flantier-Nuclear-Reglementation-1 is a fine-tuned version of HuggingFaceTB/SmolVLM-Instruct, specifically optimized for nuclear regulatory document retrieval tasks. The model demonstrates exceptional performance in analyzing technical documents, diagrams, and regulatory content in both English and French, achieving state-of-the-art results in nuclear domain applications.

Key Features

Nuclear Domain Expertise: Fine-tuned on 40,000 nuclear regulatory examples from IAEA, NEA/OECD, WENRA, EU directives, and French nuclear authorities
Multimodal Analysis: Simultaneously processes regulatory text, technical diagrams, safety flowcharts, and parameter tables
Bilingual Performance: Optimized for both English and French nuclear documentation
High Precision Retrieval: Achieves 74% accuracy (EN) and 61% accuracy (FR) on nuclear regulatory document retrieval tasks
European Sovereignty: Built on European open-source architecture for strategic autonomy in critical sectors

Benchmark

Nuclear Regulatory Document Retrieval Performance

Performance on nuclear regulatory document retrieval (NDCG@1):

Model	English	French
HuggingFaceTB/SmolVLM-Instruct	0.17	0.04
llamaindex/vdr-2b-multi-v1	0.66	0.48
racineai/Flantier-SmolVLM-2B-dse	0.69	0.57
Flantier-Nuclear-Reglementation-1	0.74	0.61

Applications

Nuclear Regulatory Compliance: Retrieve relevant safety standards and regulatory requirements
Technical Documentation Analysis: Process nuclear technical diagrams, safety flowcharts, and parameter tables
Multilingual Regulatory Search: Handle international nuclear documentation in English and French
Safety Assessment Support: Assist in nuclear safety evaluations and compliance verification

Training Methodology

This model was fine-tuned using LoRA (Low-Rank Adaptation) on our specialized OGC Nuclear Dataset, which includes:

Regulatory documents from IAEA, NEA/OECD, WENRA
European Union nuclear safety directives
French nuclear regulatory framework (ASN orders, IRSN guides)
Technical documentation from nuclear operators

The training focused on nuclear-specific terminologies including criticality, containment, radiation protection, and regulatory compliance requirements.

Dataset

Our training utilized the Organized Grouped Cleaned (OGC) Nuclear Dataset, available as an open-source resource for nuclear AI research and development.
