Emergent Design Discovery
AI's Intuition: Beyond Human Constraints
ReactorFold exhibits an emergent capability to internalize causal physical relationships, autonomously adjusting design parameters like gadolinium inventory and discovering out-of-distribution, high-performing configurations.
Autonomy
In Design Parameter Adjustment
The DPO-aligned model autonomously adjusts gadolinium (Gd) inventory beyond its training data, demonstrating genuine internalization of reactor physics principles rather than mere pattern memorization. This breaks human-imposed constraints, allowing the model to find optimal solutions by dynamically altering the number of Gd rods (e.g., from 16 to 29) to satisfy power-peaking constraints.

Unlocking Superior Performance
Quantitative analysis reveals ReactorFold's superior neutronic balance, lower power peaking factors, and ability to break conventional design symmetry to unlock higher performance.
0.1
Lower Peak Power Factor (Fq)
ReactorFold achieved an Fq approximately 0.1 lower than competing models, indicating a significantly flatter power distribution and reduced risk of local fuel damage. This metric highlights the model's ability to optimize for critical safety and performance objectives effectively.
Accelerating SMR Core Development
The ReactorFold framework offers a validated pathway to significantly accelerate the design cycle of advanced Small Modular Reactors (SMRs). By transforming design into a sequence generation task, it enables rapid exploration of novel core topologies and the autonomous optimization of critical parameters, far exceeding the capabilities of traditional iterative methods. This breakthrough can drastically reduce development time and costs, and lead to safer, more efficient reactor designs, meeting the urgent demands for carbon-neutral energy solutions. It embodies the strategic imperatives of the Genesis Mission, pushing AI to accelerate nuclear innovation.
