Eddy Current Testing Fast Breeder Reactor Heat Exchanger Laser Processing
A hybrid optical fiber scope and a laser processing head were combined with an eddy current testing un it for the inspection and repairing for Fast Breeder Reactor's heat exchanger pipes. The project propo ses an effective cost reduction method for maintenance of FBR by extension of the heat exchanger's lif etime. By the end of March 2010, a prototype probing system for heat exchanger pipes will be completed....

Eddy Current Testing Fast Breeder Reactor Heat Exchanger Laser Processing
In order to maintain FBR heat exchanger tubes, a new probe system was designed. A coupling u nit and operational software are key components in the second year. The coupling unit to com bine a high energy laser beam and optical fiberscope images was developed. The operational s oftware successfully controlled an eddy current testing device and a laser processing head....

fast reactor fiber Bragg grating health monitoring high temperature nuclear power plant strain structural integrity
A thermal-resistant fiber Bragg grating (FBG) fabricated by femtosecond laser processing was examined to evaluate the performance as a strain sensor, compared with a conventional FBG se nsor. Each FBG was affixed on a stainless-steel beam along with a strain gauge to measure the Bragg wavelength shift as a function of strain. We used the intensity of the reflection spe ctra from the FBGs as a weighting factor to determine the Bragg wavelengths. Although the strain sensitivity for the thermal-resistant FBG ...

Fiber Bragg Grating High Temperature Pulse Laser Processing Seismic Safety
Fiber Bragg Grating (FBG) is the periodic refractive-index structure in an optical fiber core, where the light of a specific wavelength is reflected. It can be used as te mperature or a distorted sensor by measuring change of the reflective wavelength of FBG. We processed FBG using a Chirped Pulse Amplification titanium sapphire laser. As a result, the peak intensity of reflective spectrum has been successfully improved from -40 dB to -24 dB. Heating test under operational temperature of Fast Breeder React...

Condition monitoring Fast Reactor FBG High temperature Strain sensor
Strain sensors, which can be used for integrity monitoring of plant components and piping during the operation period continuously, are effective from the point of view of proac tive maintenance. FBG (Fiber Bragg Grating) sensor is one of the expective sensors and is used in various plants and civil engineering and construction fields except for high te mperature service. In order to apply to the component and piping of fast reactor, heat resistance is an indispensable feature of the sensor. In this study,...
