Science communication activities based on the energy and environmental education in the Kansai Photon Science Institute and the Kids' Science Museum of Photons

Hoshiya, Taiji; Nishimura, Akihiko; Nishikawa, Masahiro*

Literacy Information and Computer Education Journal (Internet), 3(2), p.694 - 706, 2012/06

The Kids' Science Museum of Photons, which is attached to the Kansai Photon Science Institute of the JAEA and is managed as an unique and experienced study type of museum with the theme of the photon science, provides us with the mystery of light through various exhibits, theater, and experimental events. In this research, the outline of science communication activities of energy and environmental education such as recent coordinated course, the experiment booth village and the science-walker is discussed in the degree of understanding, inquiring mind and its effects.

Development of energy and environmental education in the Kids' Science Museum of Photons; Activities associated with regional administrative offices, educational institutions, and schools

Hoshiya, Taiji; Nishimura, Akihiko; Sasaki, Kazuya*; Nishikawa, Masahiro*

Enerugi Kankyo Kyoiku Kenkyu, 4(2), p.49 - 56, 2010/07

The Kids' Science Museum of Photons (KSMP), which was established in a blanch of the Kansai Photon Science Institute (KPSI), can provide us with the mysteries of light through various exhibits, theater, and science experimental events, as quite an unique museum, to be focused on the photon science. The goal of this museum is also to develop "Heart of Science" in children who can join and experience. In this phase, the KSMP has been promoting various activities of public understanding of science and technology, such as the collaboration seminar, the science festival and the teacher education program, to be associated with regional administrative offices, educational institutions, and schools. It can be explained the outline of systematically trial activities on the energy and environmental education, the collaboration lecture, the experimental village and the science-walker, from the viewpoint of the degree of understanding, the search mind and effects.

The Performance of photons rainbow-colored energy experimental lecture schools in the Kids' Science Museum of Photons

Hoshiya, Taiji; Sasaki, Kazuya*; Nishikawa, Masahiro

Reza Kenkyu, 36(4), p.221 - 225, 2008/04

The Kansai Photon Science Institute (KPSI) of Japan Atomic Energy Agency (JAEA) has been promoting various activities of public understanding of science and technology, to be focused on the photon science, which is characterized by activities on science lectures and science events based on science and experiment classrooms, by utilizing the science museum of the JAEA (The Kids' Science Museum of Photons). In this phase, the KPSI extends systematically trial activities of the science museum to be as an experimental apparatus for studying on science and technology, including the program for promoting activities on public understanding of science and technology at the region. In this report, the photons rainbow-colored energy experiments lecture schools were held on the energy conversion. About ninety percent of 142 participants can enjoy each school and get the motivation to have attraction for these fields, and these schools can be useful for elementary school members.

The Effect of neutron irradiation on mechanical properties of YAG laser weldments using previously irradiated material

Yamada, Hirokazu*; Kawamura, Hiroshi; Tsuchiya, Kunihiko; Kalinin, G.*; Nagao, Yoshiharu; Takada, Fumiki; Nishikawa, Masahiro*

Journal of Nuclear Materials, 340(1), p.57 - 63, 2005/04

 Times Cited Count:4 Percentile:32.08(Materials Science, Multidisciplinary)

This study was performed to clear the effect of neutron re-irradiation on mechanical properties to welding material un-irradiated and irradiated stainless steel. The effect of re-irradiation to these weldaments were evaluated by tensile tests, metallographical observation and hardness test. The result of tensile tests shows that ultimate tensile strength of all joints specimen were almost similar, 0.2% yield strength and total elongation were depend on the irradiation damage and weldaments or not. Therefore, fracture mechanism was not change by re-irradiation. However, brittlement of material was depend on irradiation damage and the property of deformation was sensitive by the effect of irradiation damage or the effect of welding heat.

Development of SH Wave Electromagnetic Acoustic Transducer (EMAT)

Yang, X.; Tagawa, Akihiro; Ueda, Masashi; Yamashita, Takuya; Otsuka, Yusuke*; Osafune, Kazunori*; Nishikawa, Masahiro*

The Hellenic Society of N, 0 Pages, 2003/11

This paper describes a new structure of horizontally polarized shear(SH) wave electromagnetic acoustic transducer(EMAT). The EMAT with a Halbach magnet structure shows a stronger magnetic flux density as well as ultrasonic sound pressure than that of an EMAT with a general periodic permanent magnet(PPM) structure. The measured magnetic flux density and the ultrasound directivity distributions for both the Halbach and the PPM structure EMATs are in excellent agreement with those expected form a simulation calculation. The above EMATs were also used for inspection tests of many artificial slits; and it is found that the Halbach one performs a better detectability than the PPM one.

The alkali hydrolysis experiments which seem to be important from the view point of the alteration mechanism using the following seven organic materials was performed as a part of the evaluation of the influence on the disposal of the organic materials contained in the TRU wastes. As a result of the alkali hydrolysis experiments (90$$^{circ}$$C and 91d), each organic materials became those of lower molecular weight. The degradation products were able to be detected in the solution. The organic materials seem to be degraded to the organic matters which were confirmed in this study in a long term of disposal. The degradation products were shown below. Therefore, the evaluation of the influence on the migration of radionuclides by degradation products becomes important in the future. (1)Cement additives of Naphthalenesulfonic acid and Ligninsulfonic acid ($$rightarrow$$ Naphthalenedisulfonic acid etc.) (2)Cement additives of polycarboxylic acid ($$rightarrow$$ Oligomer of distal methoxypoly ethylene glycol.) (3)Ethylenediamine-N,N,N',N'-tetraacetic acid disodium salt ($$rightarrow$$ Acetic acid desorped and cyclized organic matters from EDTA.) (4)Tributyl phosphate ($$rightarrow$$ Dibutyl phthalate, n-butanol) (5)Poly vinyl acetate ($$rightarrow$$ Acetic acid) (6)Nylon66 ($$rightarrow$$ Adipic acid, Hexamethylenediamine) (7)Cured epoxy resin ($$rightarrow$$ Glycerol poly glycidyl ether, Carboxylic acid)
