[en] This paper shortly summarizes some problems to be taken in consideration for the application of the ICRP optimization techniques to the design of nuclear facilities in order to minimize radiation exposure during the decommissioning phase. Then are examined the relevant factors in decommissioning from the point of view of radiation protection: the activation of structural materials, the dismantling and decontamination techniques, the radioactive waste. Some considerations on recycling-restricted-unrestricted use of materials and on the relationship between normal operation and decommissioning affecting the occupational exposure, are presented

[en] The European Tritium Handling Experimental Laboratory is committed to investigate the propagation modes of tritium in materials, components, equipment and process loops. As for other radiochemical facilities, a number of safety criteria and principles have been introduced into the design, construction and intended operation of the facility with the aim of optimizing the protection of both the workers and the population. This paper highlights a variety of safety aspects applied to the laboratory: confinement barriers, radiological protection, waste handling and, finally, precautions against internal and external events

[en] The evolution of fusion energy is outlined and a general overview provided of radiation protection considerations. The specific design basis for the Next Step tokamak device, as developed by the international Thermonuclear Experimental Reactor (ITER) Conceptual Design Activity is described, including its safety approach. Results of the ITER safety analysis are summarized for protection of the public, for both accidental and normal conditions, and for workers. Solid waste forecasts are also provided. Key radiation protection issues are identified, including future safety-related R and D, the role of optimization, and regulatory practice and policy. (author). 39 refs

[en] The paper presents the methods used by Working Group ENEA-EDP (Experts in Personal Dosimetry) to control the reliability of the Dosimetric Services operating in Italy and asking for the above controls on voluntary basis. Testing and irradiation test methods are explained as well as the evaluation criteria. The paper includes suggestions and guide-lines to gain the status of 'Reliable Service'. Technical equipment and operating procedures needed to pass the test are also illustrated. (author)
