Measurements of Deuteron-Induced Activation Cross
Sections for IFMIF Accelerator Structural Materials
FAPIG No. 172 pp.3`7 (2006)

The IFMIF (International Fusion Materials Irradiation Facility) is in the design planning stage as neutron source to test fusion reactor materials for high fluence neutron.
In the design of it, long-term operation that total facility is 70% at least is required. However, deuteron beam activates the structural materials these activation limits maintenance and makes long-term operation difficult. Thus the accurate estimation of deuteron-induced activity and the selection of structural materials are important.
In this work, measurements of deuteron-induced activation cross sections for aluminum, iron, copper, tantalum and tungsten were performed.

KEYWORDSFInternational Fusion Material Irradiation Facility, TIARA facility, deuteron, cross section, activation

Structural Concept of Solid Breeder Test Blanket Module for ITER
FAPIG No. 172 pp.8`12 (2006)

A solid breeder blanket was selected as the primary candidate blanket of the fusion power demonstration plant (DEMO plant) in Japan. Test blanket module (TBM) testing in ITER is the most important milestone for the development of the blanket of the DEMO plant. This paper presents a structural concept of solid breeder TBM cooled by pressurized water. The sub-module concept was adopted for this TBM to simulate the DEMO blanket structure and to endure the over-pressurization in case of the coolant ingress to box structure. Two sub-modules have multi-layer structure composed of ceramic breeder pebbles and neutron multiplier pebbles inside of box structure made of F82H.

Development of Remote Handling System Based on 3-D Shape Recognition Technique
FAPIG No. 172 pp.13`18 (2006)

In a nuclear facility, the maintenance and repair activities must be done remotely in a radioactive environment. Fuji Electric Systems Co., Ltd. has developed a remote handling system based on 3-D recognition technique. The system recognizes the pose and position of the target to manipulate, and visualizes the scene with the target in 3-D, enabling an operator to handle it easily. This paper introduces the concept and the key features of this system.

KEYWORDSFremote handling system, 3-D recognition technique

Design of Exhaust Air Monitoring System at Reprocessing Plant
FAPIG No. 172 pp.19`25 (2006)

Exhaust air monitoring systems are implemented for monitoring and alarming air-borne radioactive materials in exhaust gas from the plants.
Since the quality of the radioactive exhaust air in Reprocessing Plant is different from that of Nuclear facilities, designing new exhaust air monitoring systems and new products are required. This paper introduces the exhaust air monitoring system newly developed for Reprocessing Plants, which meets the required monitorings and multiplex, and has the quake-resistant. Each monitoring device and instruments are also designed to integrate this system.

KEYWORDSFreprocessing plant, exhaust air monitoring

Mechanism of Authentication and Its New Technologies
FAPIG No. 172 pp.26`33 (2006)

Crimes using masquerading technique are increasing. Masqurerating is to falsify the identity of the perpetrator. Secure authenication mechanism is necessary to prevent those crimes. Bio, PKI, and smart card technologies are becoming to be adopted in advanced business communities.
Electronic passports will be introduced in a few years worldwide. Banks are introducing bio-authentication mechanism to ATM networks. Goverments are distributing PKI Residential Identification Cards.

KEYWORDSFcrime masquerade identity authenication bio PKI smart card passport
