STATE ENTERPRISE "STATE SCIENTIFIC AND TECHNICAL CENTER FOR NUCLEAR AND RADIATION SAFETY"

Their core work

SSTC NRS is Ukraine's principal technical support organization for nuclear and radiation safety regulation. They provide independent safety assessments for nuclear power plants, covering reactor integrity, severe accident analysis, radioactive waste management, and long-term operation of ageing reactor fleets. Their work spans deterministic and probabilistic safety methods, structural materials degradation under irradiation, and seismic risk assessment — all critical for keeping Ukraine's 15 operating nuclear reactors safe. They also contribute to European-wide efforts on geological disposal of radioactive waste and emergency preparedness.

What they specialise in

How they've shifted over time

All seven projects started within a narrow 2019–2020 window, so the evolution is subtle but visible. Early projects (2019 starts) emphasized emergency scenarios — severe accidents, design basis events, safety margins, and emergency preparedness. The later projects (2020 starts) shifted toward long-term operational concerns: ageing management, reactor pressure vessel integrity, irradiation-induced material degradation, and probabilistic/deterministic assessment methods. This mirrors the broader European nuclear sector's pivot from accident response to life extension of ageing reactor fleets.

SSTC NRS is deepening its expertise in reactor life extension — materials degradation, pressure vessel integrity, and probabilistic safety methods — positioning itself as a key partner for any consortium working on safe long-term operation of ageing nuclear plants.

How they like to work

SSTC NRS operates exclusively as a project participant, never as coordinator, which is typical for a national regulatory support body contributing specialist technical input rather than managing large consortia. With 171 unique partners across 31 countries from just 7 projects, they work in very large European consortia (averaging ~25 partners per project). This broad network means they are well-integrated into the European nuclear safety community and accustomed to working within complex, multi-national project structures.

With 171 unique consortium partners across 31 countries from only 7 projects, SSTC NRS has an exceptionally wide European network in nuclear safety. Their reach spans virtually all EU member states plus associated countries, reflecting the pan-European nature of nuclear safety research programmes.

What sets them apart

SSTC NRS brings a perspective that few Western European partners can offer: direct operational experience with VVER-type reactors (Soviet-designed pressurized water reactors), which are the dominant reactor type in Ukraine and several EU member states. As the technical arm of Ukraine's nuclear regulator, they combine regulatory insight with hands-on safety assessment capability — a rare combination that makes them valuable for projects needing both analytical rigour and real-world regulatory context. Their involvement signals credibility in nuclear safety research, particularly for projects addressing reactor types and operational challenges specific to Central and Eastern Europe.

Highlights from their portfolio

• EURAD
  Their largest project by funding (EUR 217,938) — a flagship European Joint Programme on radioactive waste management involving dozens of partners across the continent.
• APAL
  Highly specialized work on pressurised thermal shock and reactor pressure vessel integrity for long-term operation — directly addresses one of the most critical safety questions for ageing nuclear plants.
• STRUMAT-LTO
  Bridges materials science and nuclear safety by studying irradiation-induced degradation of structural materials, combining experimental and modelling approaches for reactor life extension decisions.
