Overview of IRID R&D
Dr. Naoaki Okuzumi (International Research Institute of Nuclear Decommissioning, Japan)
Abstract
For the decommissioning of the Fukushima Daiichi Nuclear Power Station (NPS), four organizations cooperate as one team. IRID is a complex entity consisted of eighteen organizations that play a leading role in research and development (R&D) for the decommissioning of the Fukushima Daiichi NPS. IRID is conducting R&D projects including the project of "Preparation of Fuel Debris Retrieval" and "Treatment and Disposal of Radioactive Waste". IRID has developed three technologies for; 1. Intensive investigation for fuel debris and the damaged conditions inside the reactor, 2. Potential risk management and verification for the nuclear safety, 3. A reliable remote operation under high radiation environments.
As for the preparation of fuel debris retrieval, IRID is undertaking R&D projects based on three elements. Firstly, investigations using the cosmic-ray muon were performed. The distribution of fuel debris in the reactor was investigated from outside the reactor building by using the muon. The muon investigation showed that a large amount of fuel is less likely to remain in the reactor core. Secondly, detection technology that enables to directly access fuel debris in the PCV (Primary Containment Vessel) has been developed. Robots successfully entered the PCV at Unit 1. Investigation robots and devices for inside pedestal have been developed for Unit 2. Fuel debris investigation inside Unit 3 pedestal were performed by an underwater swimming robot. These robots and devices were remotely operated and successfully obtained visual data inside PCVs. Essential technologies for accessing fuel debris in the RPV or the PCV are currently developed. IRID aims to proceed with R&D for fuel debris retrieval.

Cryptography-based Security in IoT Era
Prof. Yasuyuki Nogami (Okayama University, Japan)
Abstract
In the IoT/AI era, information security must support very wide area with a connection to networks. Particularly, small devices such as 16-bit microcontroller are utilized for realizing many functionalities such as sending/receiving sensor data, processing control signals, and data formatting/protecting. As an example, auto-driving is also one of important applications of utilizing IoT devices; however, it is a challenging problem for guaranteeing its secure and safe control based on cryptographies. In the talk, elliptic curve cryptography is introduced as an IoT device-friendly public key cryptography, together with some recommended parameters and calculation algorithms. Then, some implementation difficulties and attacks from a viewpoint of hardware security are introduced. Finally, some educational projects on information security in Okayama University that gives lectures and hands-on training for students in college and engineers in industry are introduced.

Selected Researches on Artificial Intelligence Applications to Nuclear Power Plants in Korea
Prof. Poong Hyun Seong (Korea Advanced Institute of Science and Technology, Korea)
Abstract
In March 2016, the historic Go tournament was held in Korea between Korean Go champion Se-dol Lee and Alpha Go from Deep Mind. The tournament ended up with Alpha Go's victory, which shocked many people. This event triggered active researches on the application of artificial intelligence to many industrial fields including nuclear engineering in Korea. The application of artificial intelligence to nuclear power plants is expected to begin with significantly reducing the human operational and maintenance errors that account for a big portion of undesirable events in nuclear power plants and eventually to end with autonomous nuclear power plants. Along this path, the following four research area are considered. They are 1) ensuring the integrity of measurement value, 2) performing accurate diagnosis of the situation, 3) predicting the behavior of the nuclear power plants, and 4) designing the autonomous operation agent that can safely control the plant. In this talk, for the ultimate automation of nuclear power plants in Korea, what kind of researches are being performed and what the current achievements are in each area will be introduced.

Wireless Sensor Network Technologies for Applications in Nuclear Power Plants
Prof. Jing Jiang (University of Western Ontario, Canada)
Abstract
There are several distinctive considerations when deploying wireless technologies inside a nuclear power plant. They include: (1) potential interference with existing highly sensitive safety systems through electromagnetic (EM) radiation; (2) ionizing radiation in nuclear power plant may cause damages to electronic components on the wireless sensor boards in particular in an event of an accident; and (3) efficient and effective ways for data transmission and relaying over long distance in confined spaces within a nuclear power plant. This paper will consider the above issues and discuss some potential solutions. The first part will focus on wireless technologies suitable for deployment in nuclear power plants during normal operation, while the second part will focus on wireless technologies for situations under severe accident conditions. Finally, some of the latest wireless communication technologies based on distributed antennas for wireless data transfer are discussed.
