And JAERI-KAERI joint seminar has been held every three years. The 1st and 2nd JAERI-KAERI Joint Seminars were held in November 1992 at JAERI and in September 1995 at KAERI, respectively. The 3rd JAERI-KAERI Joint Seminar was held on 25 and 26 March, 1999 at the Oarai Research Establishment of JAERI. In this seminar, total participants of 84 were joined from JAERI, KAERI, Hanyang University, Japan Nuclear Cycle Development Institute, Oarai Branch of Institute for Materials Research (IMR) of Tohoku University, Nippon Nuclear Fuel Development Co., Ltd., Nuclear Development Corporation and others. Contributed presentations were 33 in three sessions; Current status and future perspectives on PIE (8 presentations), PIE techniques (11 presentations) and Evaluation of PIE data (14 presentations). Re-assembling technique for JOYO fuel, Nd-YAG laser welding technique, grain boundary analysis using FEG-TEM, lift time estimation of PWR Rod Cluster Control Assembly (RCCA) rodlet and failure analysis of Korea Nuclear Power Plant (KNP) fuel have been widely noticed as topic items on PIE. JAERI-Conf 99-009 And some comments from PIE user, were pointed out that the nano-PIE technique, the flexibility to ad-hoc demands on testing space or utilization, and the international collaboration were very important for the next generation's PIE Keywords; PIE, Hot Laboratory, Re-assembling, JMTR, JOYO, HANARO, PWR, RCCA, Nd-YAG Laser, Failure Analysis, International Collaboration JAERI-Conf 99-009 as 3 mm$i® 1999 % 3 n 25 B ~26 S 0 (1999^8^4 (mm) * 3 — \t 1999 ^ 3 n 25 , ^^ 84 14 fr©ff 33 , NCI-YAG i/--*f~ wu FEG-TEM , PWR vi PIE &wu : T311-1394 3607 This page(s) is (are) intentionally left blank. JAERI-Conf 99-009 Foreword It has been periodically carried out to bring together specialists and scientists in the field of the PIE activities and to strengthen the research cooperation between Japan Atomic Energy Research Institute (JAERI) and Korea Atomic Energy Research Institute (KAERI) through the mutual exchange of technical information on several kinds of items of Nuclear safety and Other related fields, under the Arrangement of the Implementation of Cooperative Research Program in the Field of Peaceful Uses of Nuclear between JAERI and KAERI since 1985. Between the Department of JMTR of the JAERI and the Nuclear Fuel Cycle Research Group of the KAERI, the 1st and 2nd JAERI-KAERI Joint Seminars on the PIE technology were organized by JAERI in November 1992 and KAERI in September 1995, respectively to summarize the results of mutual information exchange on the PIE activity. The 3rd JAERI-KAERI Joint Seminar was held in the HTTR main conference room at the Oarai Research Establishment of JAERI from March 25th to 26th, 1999 under the auspices of the Oarai Research Establishment of JAERI, the 2nd Seminar and three years later for summarizing the results of mutual information exchange on the PIE activity. The PIE-related persons including PIE users in and out the KAERI and JAERI took part in this seminar who belong to Hanyang University, Japan Nuclear Cycle Development Institute (JNC), Oarai Branch of Institute for Materials Research (IMR) of Tohoku University, Nippon Nuclear Fuel Development Co., Ltd. (NFD), Nuclear Development Corporation (NDC) and others. They discussed on recent topics on PIE and specially, Japanese PIE activities were briefly reviewed in this seminar by the result of participation of the JNC Oarai as a user on JMTR of JAERI. Contributed presentations of 33 were carried out in three sessions; Current status and future perspectives on PIE (8 presentations), PIE techniques (11 presentations) and Evaluation of PIE data (14 presentations) with total number of participants of 84 in two days. At the seminar, it was confirmed that key issues were to continue the mutual information change and the international collaboration and furthermore to grasp the perspectives of next generation's PIE. All the participants made an agreement to meet again in the next seminar three years later in Korea when the world-cup game on soccer will be held under the joint auspices of Japan and Korea.
