EMPRESA NACIONAL DE RESIDUOS RADIOACTIVOS SA

Their core work

ENRESA is Spain's national radioactive waste management company, responsible for the entire lifecycle of nuclear waste — from collection and conditioning through interim storage to final geological disposal. In H2020, they contribute operational expertise on waste treatment, pre-disposal processing, decommissioning of nuclear facilities, and long-term safety monitoring for disposal repositories. Their participation spans the full radioactive waste chain, from dismantling reactors to developing disposal solutions, making them a key national implementer with deep practical knowledge of real-world nuclear waste challenges.

What they specialise in

How they've shifted over time

ENRESA's early H2020 work (2015–2018) centered on the back-end of the nuclear fuel cycle — geological disposal monitoring (Modern2020) and engineered barrier research (Beacon). From 2019 onward, their focus visibly broadened into decommissioning, dismantling, and pre-disposal waste treatment, with projects like INNO4GRAPH, PLEIADES, and PREDIS. This shift mirrors the European nuclear sector's growing urgency around reactor closures and the practical challenge of managing decommissioning waste streams before final disposal.

ENRESA is moving upstream in the waste lifecycle — from final disposal research toward active decommissioning, dismantling technologies, and digital tools for managing nuclear facility end-of-life.

How they like to work

ENRESA participates exclusively as a consortium partner, never as coordinator — consistent with their role as a national implementing body contributing operational expertise rather than leading academic research programs. With 161 unique partners across 28 countries, they operate in large, pan-European consortia typical of the nuclear waste management community. Their broad network suggests they are a trusted, well-connected partner that multiple project coordinators actively seek out for Spanish nuclear waste expertise.

Extensive European network of 161 unique partners across 28 countries, reflecting the tightly interconnected nature of the nuclear waste management research community. Their reach covers virtually all EU member states with nuclear programs.

What sets them apart

ENRESA is not a research lab — they are Spain's designated national organization for radioactive waste management, which means they bring real operational constraints and implementation experience to every project they join. This makes them invaluable for consortia that need to ground research in practical, regulatory-compliant waste management. For anyone building a nuclear waste or decommissioning consortium, ENRESA provides the credibility and end-user perspective that reviewers look for.

Highlights from their portfolio

• EURAD
  Largest funding (EUR 337,570) — the flagship European Joint Programme uniting all major radioactive waste management organizations across the continent.
• PREDIS
  Second-largest funding (EUR 169,505) addressing the critical gap in pre-disposal waste treatment, covering the full chain from radionuclide characterization to package safety.
• PLEIADES
  Represents ENRESA's push into digital decommissioning — using BIM and 3D platforms to modernize how nuclear facilities are dismantled.
