- Development of lightweight telescopic boom for reactor pressure vessel research
抄録
<p>Decommissioning of Fukushima Daiichi Nuclear Power Station is a national urgent problem in Japan. To analyze and characterize the fuel debris distributed in Reactor Pressure Vessel (RPV), the optical fiber LIBS analysis method can be a promising solution. To deploy the LIBS sensor to the RPV, I have developed (1) a lightweight telescopic boom that can carry the sensor to the RPV, (2) a mechanism that stores the cable according to boom ’s expansion and contraction. The boom expands/contracts by winding/unwinding the synthetic fiber ropes. The cable storage mechanism stores the cable in a plane that is perpendicular to the extension direction in synchronization with the extension/contraction. The proposed mechanical design achieved a compact and lightweight mechanism of the boom. The mass, maximum length and payload were 3.18 kg, 6.03 m, and 2.48kg, respectively. The basic operation by a prototype model was successfully demonstrated.</p>
