Plan your next Nuclear Design Bureau session
Our independent guide breaks down Nuclear Design Bureau’s core systems so you can approach each engineering challenge methodically. By observing how the campaign, sandbox, lab, viewer, and loop interact, you’ll develop a workflow that reduces trial‑and‑error and highlights the physics that drive every outcome.
01 / THE GUIDE
Directive Analysis
Write down each technical requirement and material limit from a campaign directive. Compare these constraints across multiple missions to spot patterns that can inform your design strategy.
- Compare multiple directives to identify recurring material constraints.
- Document each directive’s success metrics for later reference.
02 / THE GUIDE
Sandbox Benchmarking
Create a simple device in sandbox mode and record its efficiency metrics. Use this baseline when adapting designs for constrained directives, noting any material savings.
- Use sandbox experiments to benchmark material efficiency.
- Save promising designs for later adaptation to directives.

03 / THE GUIDE
Criticality Lab Calibration
Perform several low‑risk core placements, watching the wall counter’s lag. Adjust reflector height in small increments to develop a feel for the exposure threshold.
- Observe the counter’s lag to gauge how close you are to criticality.
- Adjust reflector positioning incrementally to avoid hand exposure.
04 / THE GUIDE
Detonation Viewer Review
After each detonation, compare visual shockwave patterns between successful and failed tests. Identify visual cues that correlate with performance issues.
- Replay detonations to spot subtle timing issues.
- Note visual differences between successful and fizzled blasts.
05 / THE GUIDE
Loop Documentation
Maintain a log that records design choices, simulation parameters, detonation outcomes, and refinement actions. Over time, this log reveals which adjustments most improve k‑effective and blast efficiency.
- Keep separate saves for each major design iteration.
- Log simulation outcomes to track improvement over time.
