Purpose and scope
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.
Assessment architecture
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.
Readiness scale
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 |
Evidence and confidence
Indicator judgements are evidence-led. Evidence coverage, verification and confidence are reported separately from readiness performance.
Pillar framework
| 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% |
Aggregation
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.
Annual assessment governance
Working assessments may calculate internally, but public headline assessments must complete the configured review, assurance, approval and publication workflow.
Interpretation
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.
