AI Analysis
Safety Assessment
All safety parameters within acceptable limits. Negative reactivity coefficients confirmed.
Performance Insight
Power distribution shows good uniformity. Peak-to-average ratio of 1.42 is within design limits.
Optimization Suggestion
Consider adjusting control rod position to reduce reactivity margin to 15 pcm for optimal burnup.
Pattern Recognition
Flux distribution matches expected ALFRED core pattern with 98.7% correlation.
