Handbook of Generation IV Nuclear Reactors, First Edition, p.283 - 307, 2016/00
Handbook of Generation IV Nuclear Reactors is comprehensive resource on the research and advances in generation IV nuclear reactor concepts and the first edition is issued in 2016. The authors wrote the chapter 11: Generation IV nuclear reactor concepts: Japan, where developments activities on sodium cooled fast reactor in Japan are shown. Especially, concept of Japan sodium-cooled fast reactor (JSFR) is explained on the points of innovative technologies and safety enhancements after the TEPCO Fukushima Daiichi Nuclear Power Plant accident.

For decommissioning of the Fukushima Daiichi Nuclear Power Station, installation of an optical fiber seismic vibrometer using a specially designed robotic system was demonstrated. A water tank with 4.5m diameter and5m depth was used as a demo plant of tank type critical assembly. Micro earthquake response of a water tank was detected by the optical fiber seismic vibrometer. Vibration characteristic of the window of the water tank was monitored by laser Doppler interferometer.

This study describes the results of a series of seismic analyses conducted to clarify how plastic deformation of a pipe and its support structures affects the seismic response of the entire piping system. The analyses conducted include; plasticity is considered for (1)the support structure only, (2)the piping only and (3)both the piping and the support structure.

This paper describes the results of a series of seismic analyses conducted to clarify how plastic deformation of a pipe and its support structures affect the seismic response of the entire piping system. The first analyses include; plasticity is considered for (1) none, (2) the piping only, (3) the support structure only and (4) both the piping and the support structure. The second analyses are parametric survey of yield load and post yield stiffness of the restoring force characteristics of support structures.

The second analyses are parametric survey of yield load and post yield stiffness of the restoring force characteristics of support structures. The results of the first analyses have revealed important implications on the seismic design of piping systems by elastic-plastic response analysis.
