With the rapid progress of the utilization of Information Technology (IT), IT infrastructure (network environment and information system) became crucial as a lifeline for promoting business. At the same time, changes in the circumstances surrounding the IT infrastructure globalize the threat of cyber attacks and increase the risk of the information security such as unlawful access to an information system, viral infection, an alteration of a website, disclosure of subtlety information, destruction of an information system and so on. Information security measure is an important issue in Japan Atomic Energy Agency (JAEA). In order to protect the information property of JAEA from the threat, Center for Computational Science & e-Systems (CCSE) has been taking triadic measures for information security: (1) to lay down a set of information security rules, (2) to introduce security equipments to backbone network and (3) to provide information security education. This report is a summary of the contents of the information security education by e-learning.

It is very important to evaluate radioactive inventory and an amount of radioactive waste accurately for both the planning and the safety assessment on Fugen's decommissioning. Fugen had carried out various radioactive inventory investigations, activation evaluations by materials sampling, neutron measurements, contamination evaluation by investigation of radiation control records, etc. since operation period because Fugen uses heavy water as moderator and its core structure is different from that of LWR. And then, radioactive inventory was evaluated using those investigation data. Moreover, an amount of radioactive waste was estimated by the classification for the radioactive waste disposal based on the evaluated radioactive inventory results. This paper is intended to introduce the evaluation methods and results of the radioactive inventory and estimation of an amount of radioactive waste for Fugen.
