ATMEA meaning

In legal practice, ATMEA denotes the Franco–Japanese reactor development venture and its ATMEA1 generation iii+ pressurised water reactor (PWR) design, a term commonly used in nuclear new‑build procurement, licensing and financing documentation. It is not defined in legislation or case law; rather, it is a descriptive industry label appearing in contracts, corporate governance papers and regulatory filings. ATMEA was originally a joint venture between Mitsubishi Heavy Industries (mhi) and areva to develop, market, licence and sell a Generation III PWR. Following Areva’s restructuring and EDF’s acquisition of “New NP”, ownership of the ATMEA project is now held 50:50 by EDF and MHI, with a special share held by Framatome. References to ATMEA in legal documents typically concern: identification of the contracting/vendor entity; intellectual property and technology transfer/licensing; export control and sanctions compliance; nuclear liability and indemnity allocation; and host‑state reactor design approval and site licensing, alongside supply chain and EPC terms. Usage is broadly consistent across England & Wales, Scotland and Northern Ireland (where it arises mainly in cross‑border advisory, given the current fleet). In Ireland, ATMEA is generally encountered in advisory and supply‑chain contexts rather than domestic deployment. Accurate definition matters for allocating rights, liabilities, governing law/jurisdiction and regulatory approvals.
