Interactive sizing tool
How many reactors would your load require?
Use a transparent planning calculation to compare unit counts across representative designs. It is a scale tool, not a siting, reliability, licensing or engineering model.
Planning assumption, not a guarantee for any reactor or project.

Formula: required nameplate MW = continuous load × (1 + reserve margin) ÷ planning capacity factor. Unit count is rounded up. This intentionally does not model outages, grid constraints, redundancy rules, heat demand, ramping, transmission or project-specific performance.
