GNPRI uses a criterion-referenced 0–5 scoring scale across 38 indicators grouped into 10 weighted pillars.
GNPRI is an independent evidence-based composite readiness index that tracks Ghana's progress across ten weighted pillars and 38 criterion-referenced indicators. It is designed for longitudinal monitoring and policy analysis, not as a substitute for regulatory licensing, IAEA review missions or government decisions.
Collect and verify documentary and institutional evidence.
Assess the approved quantitative and qualitative indicators.
Group indicators within the weighted readiness architecture.
Apply the approved indicator and pillar weights.
Produce the national GNPRI score on the 0–5 scale, with a normalized percentage equivalent and readiness band.
The Ghana Nuclear Power Readiness Index (GNPRI) is an evidence-based composite framework for tracking national preparedness for nuclear power development. It supports longitudinal monitoring, policy analysis and public communication and does not replace regulatory licensing, sovereign approvals or formal IAEA review missions.
The methodology organises readiness into 10 pillars and 38 indicators. 28 indicators are designated critical and are subject to threshold checks. The framework is cross-referenced to 19 IAEA nuclear infrastructure issues.
Indicator, pillar and national readiness are expressed primarily on a 0–5 scale. Normalized percentages are secondary equivalents used for communication only.
| Score | General interpretation |
|---|---|
| 0 | No demonstrated readiness |
| 1 | Very limited readiness |
| 2 | Early-stage readiness |
| 3 | Moderate readiness |
| 4 | Strong readiness |
| 5 | Advanced readiness |
Indicator judgements are evidence-led. Evidence coverage, verification and confidence are reported separately from readiness performance.
| Code | Pillar | Weight |
|---|---|---|
| P01 | National Policy and Political Commitment | 10.0% |
| P02 | Legal and Regulatory Readiness | 12.0% |
| P03 | Institutional Coordination and Programme Governance | 10.0% |
| P04 | Owner/Operator Preparedness | 10.0% |
| P05 | Financing and Investment Readiness | 12.0% |
| P06 | Grid and Energy System Readiness | 10.0% |
| P07 | Human Resource and Knowledge Capacity | 8.0% |
| P08 | Site, Environmental and Land Preparedness | 12.0% |
| P09 | Safety, Security, Safeguards and Emergency Readiness | 12.0% |
| P10 | Stakeholder Engagement and Public Trust | 4.0% |
Indicator results are aggregated within their approved pillars and pillar results are aggregated using the approved weighting architecture to produce the national GNPRI score. The calculation engine preserves the 0–5 scale as the canonical readiness measure.
Working assessments may calculate internally, but public headline assessments must complete the configured review, assurance, approval and publication workflow.
GNPRI results should be read together with pillar and indicator performance, evidence confidence, assessment coverage and the methodology version in force for the relevant assessment year.
The score summarizes evidence-supported readiness across the approved GNPRI pillars. It is a monitoring and analytical measure, not a regulatory licence or IAEA milestone determination.
Indicators are weighted within pillars and pillars are weighted in the national aggregation according to the approved methodology. Pillar weights total 100%.
GNPRI uses documentary, institutional and programme evidence subject to evidence-confidence and verification controls.
Historical movement should be read together with evidence confidence, changes in programme conditions and methodology version.
