Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of Japan Atomic Energy Agency (JAEA) celebrated its 10th anniversary in December 2020. One of its pillars is capacity building support mainly to Asian countries. 183 trainings were implemented with more than 4,600 participants since its establishment, however, the COVID-19 pandemic impacted in the implementation of the trainings. ISCN/JAEA has started to develop the online trainings since April 2020, and implemented two regional trainings, Physical Protection and State System of Accounting for and Control (SSAC) for IAEA Safeguards in October and November 2020, respectively. The efforts continue in further development of trainings/workshops, including the regional training on Additional Protocol for IAEA Safeguards Agreement Commodity Identification Training, and other two national workshops with foreign instructors. Online training can provide not only training opportunities for those who have difficulty in traveling for security and safety reasons including under the travel restriction by COVID-19 pandemic, but also could serve in making them more effective and efficient, especially by the combination with in-person trainings. The pandemic, as a result, accelerate ISCN/JAEA to develop and implement the online trainings, which key is the international collaboration with the partners including IAEA, DOE/NNSA and Sandia National Laboratories and International Nuclear Nonproliferation and Security Academy (INSA) of the Korea Institute of Nuclear Nonproliferation and Control (KINAC). This paper will provide the efforts of ISCN/JAEA how to address the online training development and implementation, current status, lesson learned, and future plan.

International forum on peaceful use of nuclear energy and nuclear non-proliferation was held at Gakushi-kaikan, Tokyo on February 2-3, 2011 in cooperation with The Japan Institute of International Affairs (JIIA) and The University of Tokyo Global COE. In our International Forum, we would like to encourage active discussion of international challenges to and solutions for compatibility between peaceful use of nuclear energy and nuclear non-proliferation, and international cooperation for emerging nuclear energy states. It was successfully carried out with as many as 310 participants and a lot of discussions. This report includes abstracts of keynote speeches, summary of panel discussions and materials of the presentations in the forum.

FeMnSi-based shape memory alloy (SMA) is expected to be utilized for pipe installations and large structural members. Since the shape recovery action in these applications must evolve under a stress, it is important to grasp the shape recovery behavior under a controlled stress. In this study, the shape recovery behavior of FeMnSi-based SMA under a constant stress is investigated in detail, and the interpretation based on the mechanism of stress-induced martensitic transformation, which controls the shape recovery action of FeMnSi based SMA, is conducted. The stress applied to oppose the reverse transformation decreases the degree of shape recovery and increases shape recovery temperature. On the other hands the stress applied to assist the reverse transformation increases the degree of shape recovery and decreases recovery temperature. The effect of the type and amount of prestrain on the shape recovery force is also studied.
