[en] ISS needs tremendous amount of work due to the overflow of the information from each Member State and from the open source. Every Member State has different types of SSAC in term of the function, structure and activities. This paper is prepared to describe the role of the Korean SSAC in preparing the implementation of additional Protocol. For more than a year after the adoption of model additional protocol in the board of governors, Korean SSAC investigated the status of domestic nuclear industry and concluded as follows; 1. Korean industry has few activities listed in Annex 1 pursuant to article 2.a.(iv) of the additional Protocol mainly due to the electricity-oriented policy on the nuclear energy. 2. Implementation of additional Protocal may not hamper the development of peaceful nuclear activities. 3. Current atomic energy act does not cover the scope of the additional Protocol. 4. Before the signature of the Protocol, technical consultation with the Agency is indispensible. 5. New safeguards system needs closer cooperation between the Agency and the SSAC. The role of SSAC should be changed accordingly. (Yi, J. H.)
