Application of the microcapsule fabrication technology to magnetic particle testing

Fuymi ITO, Akihiko NISHIMURA (Japan Atomic Energy Agency), Takayoshi NORIMATSU (Osaka University) and Keiji NAGAI (Tokyo Institute of Technology)

Abstract
The purpose of the research is to apply the micro capsule technology to the facility maintenance. The micro capsule technology for laser fusion target was developed at the institute of laser engineering Osaka University. We have a plan to apply the fabrication technology of polystyrene micro capsules to the facility maintenance where the magnetic particle testing for complex piping system is investigated.

Keywords
fusion reaction, micro capsule, polystyrene, maintenance technology, magnetic particle testing

Study of non-destructive evaluation for ceramics materials

Yoshihiro NISHIMURA, Naoki KONDO, Hideki KITA and Takayuki SUZUKI (National Institute of Advanced Industrial Science and Technology (AIST))

Abstract
Ceramics materials are superior to metal materials in their thermal stabilities and in their stiffness. However, the behavior sin their destructure are often too sudden and sharp to prevent. It is important to detect flaws before making use of them. The probabilities that structural material has at lease a fatal flaw in portion to cubic volume of them. It is difficult to detect flaws in a large scale of material. We proposed the method to assemble a large structural part of many small units whose qualities are guaranteed by adhering them together. We measured flaws in ceramics materials using X-ray CT and Ultrasonic Testing.

Keywords
Ceramics materials, X-ray CT, UT, Silicon nitride

Development of underwater High-Definition camera for the confirmation test of core configuration and visual examination of BWR fuel

Masato WATANABE, Kenji TUJI and Keisuke ITO (CHUBU Electric Power Co., lnc.)

Abstract
The purpose of this study is to develop underwater High-Definition camera for the confirmation test of core configuration and visual examination of BWR fuels in order to reduce the time of these tests and total cost regarding to purchase and maintenance. The prototype model of the camera was developed and examined in real use condition in spent fuel pool at HAMAOKA-2 and 4. The examination showed that the ability of prototype model was either equaling or surpassing to conventional product expect for resistance to radiation. The camera supposes to be used in the dose rate condition of under about 10 Gy/h.

Condition Monitoring System by vibration method

Tatsuya FUKUNAGA (Asahi Kasei Engineering Corporation)

Abstract
The necessity of a stable driving of equipment and effective maintenance achievement rises, and the effectiveness of CBM (Condition Based Maintenance) has been recognized again in recent years. It is a vibration diagnosis technology of the rotating equipment that especially a lot of the results exist. We have aimed at the introduction of the vibration diagnosis technology in Japan since fast time (middle of the 1970's), and are working on the commercialization of the diagnostic system positively. Here, it introduces the outline of portable vibration diagnostic system (MD-320) and online vibration diagnostic system (e-LEONEX).

Keywords
CBM (Condition Based Maintenance), vibration diagnostic system
