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

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

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.
