Development of the Institute of Nuclear Technology – Radiation Protection (INT-RP) started in 1960 around the Research Reactor. The INT-RP was established as an independent Institute in 1986. It is organized in seven laboratories:

  • Nuclear Research Reactor Centre
  • Health Physics & Environmental Health Laboratory
  • Environmental Radioactivity Laboratory
  • Environmental Research Laboratory
  • System Reliability & Industrial Safety Laboratory
  • Solar & Other Energy Systems Laboratory
  • Thermal Hydraulics & Multiphase Flow Laboratory

Research in the corresponding fields is carried out along with the provision of advanced technology services.
INT-RP competes successfully for research funds at a national as well as at a European level. Third party funding for the Institute for the period 2003-2007 was 15 million Euros. INT-RP’s personnel consists of 134 staff members classified as: 38 permanent researchers; 49 technical and other support scientists; 23 scientists under fixed- term contracts and 24 PhD candidates.
Scientific and Technical Know-how

In addition to the high quality research, reflected in the publications in international scientific journals publications, INT-RP:

  • Operates the only Experimental Nuclear Reactor in Greece (5MW) (with applications in neutron scattering techniques, nuclear analytical techniques, new materials and in biological tissue sterilization)
  • Operates an integrated radiation protection centre in Greece
  • Possesses expertise and facilities for radioactive waste treatment
  • Maintains an integrated laboratory of Environmental Radioactivity Monitoring in Greece, with an extensive network of sampling/measuring/monitoring stations covering the entire country
  • It operates a state-of the art atmospheric fine and ultrafine aerosol characterization monitoring site
  • Is active in the field on nuclear fusion with emphasis on technology. It is the coordinator of the Greek Programme of Controlled Thermonuclear Fusion
  • It has expertise in the evaluation and estimation of the implications of overexposure to ionising radiation using biological dosimetry methods. It has been selected by the IAEA as a laboratory for the standardization of these methods
  • It has developed knowhow for the integrated risk assessment of complex technological systems of new technologies, as well as the assessment of occupational risk along with the associated uncertainties. This know-how has been used on behalf of the Greek Ministries of Environment and Development, in the safety evaluation of Greek chemical companies according to the SEVESO Directive as well as in the risk assessment of several industrial installations
  • Applies an integrated R&D approach to environmental problems combining diagnosis, prognosis, impact and pollution-mitigation technology as well as software development (ISO 9001) and measurements (ISO 17025). Provides a broad range of services to Public and Private Organizations in Greece and abroad
  • Operates two accredited laboratories ERL and EREL in PM10 aerosol measurements in the atmospheric environment
  • Develops and applies advanced software tools for hydrogen safety as well as materials for improved hydrogen storage
  • Pursues an integrated approach on R&D in the area of thermal solar energy utilization, by means of high-performance solar collectors combined with thermal storage for both low and high temperature applications
  • Operates the only accredited Laboratory for the evaluation of the performance of solar energy systems and the development of methods for qualification and characterization of energy products (ISO, EN)
  • Develops state-of-the-art scientific software for micro-nano-particle dynamics and biofluid flow applications
  • Possesses an advanced computer cluster capable of more than 150 parallel processes and integrated in the world GRID system
  • It has expertise in molecular and cytogenetic evaluation of hematological neoplasias. It includes the ‘‘Cytogenetic reference lab’’ for the Hellenic Society of Hematology, providing centralized cytogenetic services to all Greek hospitals.

The Institute of Nuclear Technology - Radiation Protection (INT-RP) was founded in 1987 following the gradual merging of the Divisions of Nuclear Technology, Radiation Protection and Environmental Radioactivity Monitoring of the former Nuclear Research Centre 'Demokritos'. The research activities of INT-RP started in the late 50ies. Since that time the personnel and the facilities of INT-RP have been the main research / know-how centre and connecting node with International organizations in the areas of nuclear technology and radiation protection in Greece. It has also been the implementation branch of the regulatory and licensing activities of the Greek Atomic Energy Commission (GAEC). Since 1989, when the GAEC was established as an independent body, the regulatory and licensing activities have being gradually transferred from INT-RP to the GAEC. The personnel of INT-RP consists of 29 research scientists and 30 technicians. The facilities of INT-RP, worth 100 Million $US (1989), include:

  • An open-pool 5MW Research Reactor, equipment for neutron dosimetry and neutron activation analysis.
  • Systems for radiation measurements of environmental samples along with the national network of environmental radioactivity measurement stations
  • Radiochemistry laboratory for experimental low-level radioactive waste treatment
  • An 80 m height meteorological mast with four sampling levels and data processing centre
  • Laboratory for assessing the thermohydraulic performance of solar systems
  • System for biological dosimetry with radiation (X, a, neutron) set-ups and a basic cytogenetics laboratory
  • Computing facilities including a network of workstations and PC's, for the on-line and off-line data collection and processing, related software.
