2.1 Comparative Multi-Criteria Assessment Criteria for Energy Assets
The methodological framework for evaluating the feasibility and economic yield of nuclear lifetime extension relies on an integrated synthesis of material aging diagnostics and capital expenditure accounting. Assessing asset longevity requires cross-referencing Periodic Safety Review documentation with empirical degradation metrics of non-replaceable primary circuit components [7]. Secondary water chemistry regimes and coolant interaction histories provide critical empirical baselines for verifying that structural embrittlement and corrosion rates remain well within regulatory design margins [8]. By systematizing technical monitoring records and planned refurbishment outlays, the evaluation establishes the net capital requirement necessary to sustain operation beyond initial design limits. These capital parameters are subsequently incorporated into comparative generation cost models, allowing the marginal cost of extended operation to be evaluated against alternative baseload replacement options. This structured multi-criteria approach ensures that downstream industrial competitiveness indicators reflect rigorous safety margins and realistic equipment renewal schedules without reliance on unverified operational assumptions.
