Application of X-ray computer tomography for observing the central void formations and the fuel pin deformations of irradiated FBR fuel assemblies

Katsuyama, Kozo; Nagamine, Tsuyoshi; Furuya, Hirotaka

IEEE Transactions on Nuclear Science, 57(5), p.2714 - 2718, 2010/10

 Times Cited Count：1 Percentile：11.72(Engineering, Electrical & Electronic)

In order to observe the structural change in the interior of irradiated fuel assembly, the non-destructive post irradiation examination technique using X-ray computer tomography (X-ray CT) was developed. In this X-ray CT system, the 12 MeV X-ray pulses was used in synchronization with the switch-in of the detector to minimize the effects of the $$gamma$$ ray emissions from the irradiated fuel assembly, and then clear cross section CT image could be successfully obtained.

Status of development on $$^{99}$$Mo production technologies in JMTR

Inaba, Yoshitomo; Iimura, Koichi; Hosokawa, Jinsaku; Izumo, Hironobu; Hori, Naohiko; Ishitsuka, Etsuo

Proceedings of 1st International Conference on Advancements in Nuclear Instrumentation, Measurement Methods and their Applications (ANIMMA 2009) (USB Flash Drive), 8 Pages, 2009/06

The Japan Materials Testing Reactor (JMTR) is now under refurbishment, and the operation of the new JMTR will be started in FY 2011. The new JMTR has a plan to produce $$^{99}$$Mo, which is the parent nuclide of $$^{99m}$$Tc, and two $$^{99}$$Mo production technologies have been developed; the one is a solid irradiation method, and the other is a solution irradiation method. $$^{99}$$Mo production in the JMTR will be started by the solid irradiation method, and it was found that the JMTR can produce about 20% of the demand for $$^{99}$$Mo in Japan. In the solution irradiation method, the fundamental characteristics of the aqueous molybdate solutions selected as the candidates for the irradiation target were cleared.
