Implementation Status of the Additional Protocol at KAERI

KAERI submitted the initial expanded declaration in Aug. 2004 pursuant to its AP, and the IAEA has performed the Complementary Access (CA) for verification of the correctness and completeness of the ROK's initial declarations. Since then, the ROK has submitted the expanded declarations (ED) on the nuclear fuel cycle-related R and D activities not involving nuclear material by 15 May of each year to IAEA, and the IAEA has performed the complementary access in order to assure the absence of undeclared nuclear material and activities based on the ED. This paper describes the experiences of AP implementation, internal procedures and the computerized system for preparing the ED including the status of the CAs at KAERI. KAERI has continuously established an optimized implementation system in order to effectively cope with the preparation of expanded declarations submitted to IAEA and CAs performed under AP. However, it still remains about difficulties to make a decision on whether a R and D project is related to nuclear fuel cycle and it is not included in the theoretical or basic scientific research during the preparation of EDs at KAERI. There have been a few disagreements about the authorized activities of CA performed at KAERI site between IAEA inspector and nuclear control department of KAERI. Most issues occurred during the implementation of AP were discussed and resolved during the implementation working group meeting with IAEA
