The Nuclear Energy Agency (NEA) is a specialised agency of the Organisation for Economic Co-operation and Development (OECD), headquartered in Boulogne-Billancourt (Paris). It was established as the European Nuclear Energy Agency in 1958 and assumed its current name in 1972 when non-European OECD members were admitted.

Mission

The NEA mission, as stated by the OECD, is to assist its member countries in maintaining and further developing "the scientific, technological and legal bases required for the safe, environmentally sound and economical use of nuclear energy for peaceful purposes". Compared to the IAEA, the NEA's focus is on technical depth among advanced nuclear nations rather than universality.

Standing committees

NEA work is structured around seven standing technical committees, each supported by working parties and expert groups:

  • CNRA — Committee on Nuclear Regulatory Activities.
  • CSNI — Committee on the Safety of Nuclear Installations.
  • CRPPH — Committee on Radiological Protection and Public Health.
  • RWMC — Radioactive Waste Management Committee.
  • NDC — Nuclear Development Committee.
  • NSC — Nuclear Science Committee.
  • CDLM — Committee on Decommissioning of Nuclear Installations and Legacy Management.
  • NLC — Nuclear Law Committee.

Joint projects

The NEA hosts several joint experimental and analytical projects funded by member countries' regulators and industry. These include:

  • Halden Reactor Project (1958-2018) and its successor activities at IFE Halden.
  • CABRI — fuel-rod transient testing.
  • STEM-PWR / THAI / PHEBUS-FP — severe accident research.
  • BSAF / PRISME — fire and severe-accident analysis.
  • NEA Data Bank — nuclear data services and computer-program library.

High Priority Request List (HPRL)

The Nuclear Science Committee maintains the High Priority Request List (HPRL) of nuclear-data measurements needed for the safety and design of current and future reactors and fuel cycles. The HPRL is a recurring touchstone for regulators wishing to align national research with international priorities — see the seeded entry on NEA HPRL Priorities in this wiki.

Multinational Design Evaluation Programme

The MDEP brings together regulators (NRC, ASN, ONR, CNSC, STUK, KINS, NRA-Japan, SUJB, etc.) to share design-evaluation experience and harmonise expectations for new reactor designs, including the AP1000, EPR, APR1400, ABWR, ESBWR, and small modular reactor concepts. MDEP outputs feed into national licensing without replacing it.
