# Nuclear SMR Skill

> **Trit: +1 (GENERATOR)**

## Overview

Small Modular Reactor integration for Plurigrid energy dominance. Bridges neutronics simulation (OpenMC/MOOSE), categorical databases (ACSets), and on-chain coordination (Aptos).

## When to Use

- SMR simulation and safety analysis
- Mesh generation for finite element multiphysics
- Monte Carlo neutronics with deterministic coloring
- Grid dispatch optimization for hybrid energy systems

## Key Repositories

| Repository | Stars | Purpose | GF(3) Mapping |
|------------|-------|---------|---------------|
| `idaholab/moose` | 1.7K | Multiphysics FEM | +1 Generator |
| `openmc-dev/openmc` | 931 | Monte Carlo neutronics | +1 Generator |
| `stellarmesh` | 66 | Mesh generation | 0 Coordinator |
| `idaholab/HERON` | - | Hybrid systems | -1 Validator |

## SMR Advantages for Developing World

1. **Factory-built**: Ship assembled, reduce on-site complexity
2. **Passive safety**: No external power needed for shutdown (valence = +3)
3. **Load-following**: Complement variable renewables
4. **Smaller upfront capital**: $1-3B vs $10B+ for traditional
5. **Co-generation**: District heating + desalination

## QRI Valence Integration

Grid states mapped to XY model topology for bankable assets:

| Grid State | Valence | Vortices | Action |
|------------|---------|----------|--------|
| Blackout | -3 | many | emergency-withdraw |
| Brownout | -2 | some | gradual-withdraw |
| Unstable | -1 | few | hold-cautious |
| Balanced | 0 | none | hold |
| Surplus | +1 | annihilating | hold-growth |
| Export-ready | +2 | none | deposit |
| Dominant | +3 | none | deposit-compound |

## Commands

```bash
# OpenMC simulation with Gay.jl coloring
julia --project=. -e 'using OpenMC, Gay; run_simulation(seed=137508)'

# Mesh → ACSet conversion
julia -e 'using ACSets, StellaMesh; mesh_to_acset(load_mesh("reactor.msh"))'

# Deploy SMR operator registry
aptos move publish --package-dir wev_move_contracts --named-addresses wev=default

# HERON optimization
python -m heron --input smr_hybrid_config.yaml
```
