Evolution and development of laws, regulations, criteria and human resources to ensurethe safe decommissioning of nuclear facilities in Thailand

摘要

The Research Reactor, TRR-1 (renamed TRR-1/M1 after core replacement) in Thailand hasbeen operated for more than 43 years. This ageing reactor will be facing shutdown in the near future. Laws andRegulations have been continually developed to assure the safe operation of nuclear facilities, particularly of theresearch reactor, and to ensure the safe decommissioning of the reactor after its operational life. However, theThai nuclear legislation is still not applicable to a number of areas. Office of Atoms for Peace is working towarddevelopment of a new consolidated Act. In addition, the licensing steps for modification and decommissioningare added to the new Ministerial Regulation and to the new guidance documents on the licensing process forresearch reactors. Regulations, guidance and criteria for approval of decommissioning are being developed usingthe IAEA Safety Standards Series as the main basis for drafting. Human resource development is considered asone of the key important factor to ensure safe decommissioning of the installation. Staffing and training of theoperating organization and the regulatory body personnel have been addressed to ensure the achievement ofcompetency level. Simple methods and technologies are the best means for implementation while learning fromexperience of others will help and support us in our attempt to be the 'second First'. IAEA advice and assistanceon the decommissioning of nuclear facilities in countries with limited resources is desirable.
