Existing nuclear fleet: Phase out nuclear power and plan the dismantling of sites
Direction of change: abolition of a scheme, compared with current law.
The lever. Future of reactors in service: extension of their lifetime, closures, or gradual phase-out of nuclear power. Direction rule: ↑ longer lifetime, reopenings; ↓: closures, phase-out.

lever that cannot be costed
Lever with no coefficient in the cost schedule: the position is compared, not costed.
Current law, sources and limits of the cost schedule
Current law. Multiannual energy programme (PPE3, decree of February 2026): continued operation of existing reactors up to sixty years, or even beyond, under the supervision of the Autorité de sûreté nucléaire et de radioprotection (nuclear safety and radiation protection authority); no reactor closure scheduled.
Horizon. Not applicable for now.
Limits. Not costed at this stage. A nuclear phase-out or an extension beyond sixty years mainly involves investment costs (grand carénage refurbishment programme, decommissioning, replacement capacity) and effects on the electricity price, borne largely by EDF and not by the State budget; no comparable public costing is cited.
- Maire-info, « La programmation pluriannuelle de l'énergie enfin publiée », 13 février 2026, 2026-02-13: « « Côté nucléaire, la PPE confirme la poursuite de l'exploitation des réacteurs existants jusqu'à soixante années, voire au-delà » »
How to read these amounts. These are static costs and revenues, with no feedback effect, over a full year: nothing on growth, employment or the revenue that economic activity would gain or lose. A higher net cost does not on its own make a worse policy, nor net savings a better one: each programme rests on an economic model (demand-led stimulus, lower compulsory levies, consolidation of the public accounts…) that the cost schedule does not settle. GDP itself measures a volume of activity, not well-being or the usefulness of what is produced. Economic models and feedback effects.
