The Library of Japan Atomic Energy Agency (JAEA) has developed the special website on Fukushima Dai-ichi Nuclear Power Station accident from April 4, 2011. This website is provided both in Japanese and English. It disseminates over 15,000 bibliographic and full-text records, such as JAEA's research results, academic journal articles, conference papers, technical reports etc. In this paper, the authors introduce the special website on Fukushima Dai-ichi Nuclear Power Station accident and discuss some challenging issues to develop archive.

The TF coil conductor was composed of 900 NbSn superconducting strands and 522 Cu strands protected by circular sheath tube (jacket) with the outer diameter of 43.7 mm. The jacket section is a seamless tube made of modified 316LN. JAEA tested different types of tensile specimen (Japanese Industrial Standards (JIS) type and ASTM type) cut from jacket. ASTM type specimen has longer and wider reduced section than those of JIS type specimen. Elongation of as received condition is not dependent on specimen shape. But after cold work and aging, the elongation is deteriorated due to a sensitization and scattering of elongation is larger than that of as received condition. Fracture mode of aged jacket is "cup and cone fracture", which have a mixture of inter granular at center area and trans-granular factures in circumference area. It is considered that initiation of fracture is more sensitive on test specimen shape with low ductility.

The Japan Atomic Energy Agency (JAEA) has the responsibility to procure 25% of the ITER Toroidal Field coil conductors as the Japanese Domestic Agency (JADA) in the ITER project. The TF conductor is a circular shaped, cable-in-conduit conductor, composed of a cable and a stainless steel conduit (jacket). The outer diameter and maximum length of the TF conductor are 43.7 mm and 760 m, respectively. JAEA has constructed newly conductor manufacturing facility. Prior to starting conductor, JAEA manufactured a 760-m long Cu dummy conductor as process qualification of dummy cable, the jacket sections and fabrication procedures, such as welding, cable insertion, compaction and spooling. Following qualification of all manufacturing processes, JAEA has started to fabricate superconducting conductors for the TF coils.

Japan Atomic Energy Agency has a responsibility for procurement of the ITER toroidal field coil conductors as Japanese Domestic Agency (JADA) of the ITER project. The TF conductor is a circular shaped cable-in-conduit conductor, which is composed of cable and stainless steel conduit (jacket). The outer diameter and wall thickness of jacket are 43.7mm and 2mm, respectively. The cable consists of 900 NbSn superconducting strands and 522 Cu strands. The length of TF conductor is 780m in maximum. Preparation of conductor fabrication was completed in December 2009. And then, to demonstrate a conductor manufacturing procedure, JADA fabricated 780m-long Cu dummy conductor as a process qualification. Finally, the 780m-long Cu dummy conductor has been successfully completed, ahead of other domestic agencies that are in charge of TF conductor procurement. Since all of manufacturing processes have been qualified, JADA started to fabricate superconducting conductors for TF coils.

Circulation of scientific information improves internationally today, and English which is "universal language" takes the leading part for scientific communication. On the other hand, non-English articles are still "gray literatures" due to language barriers though physical circulation improves as well as English articles. In the International Nuclear Information System (INIS) database operated by the International Atomic Energy Agency (IAEA), bibliographic information such as title and abstract etc. is written in English. This feature of the INIS database contributes to international circulation of scientific information of the nuclear field. However, titles of journals written by non-English language were described by transliterated Roman alphabet, non-native users cannot understand natures and subjects of journals written by non-English language. Non-native users cannot understand the nature of the journal with this journal title description, and then they fail to get the useful article. This language barrier should be broken through as soon as possible for circulation improvement of journals written by non-English language. So we develop a special journal titles translation list of journals written in Japanese for the INIS database, as attempt to improve circulation of articles in journals written by non-English language. We will release this list on the INIS database for circulation improvement of journals written by non-English language, and we will implement the list into the database for user's convenience in the future.

Survey on usage of electronic journals in Japan Atomic Energy Agency

Japan Atomic Energy Agency performed the survey on usage of electronic journals using "Science Direct" provided by Elsevier Science, 2006. Although JAEA researchers are interested in 1,028 titles among physics, chemistry, engineer, medicine, social sciences etc., it is found the 80% of total downloads was occupied by only 102 journal titles. To satisfy researcher's needs for electronic journals effectively, identification the core journals by librarians based on user's needs is rational way in cost. By shifting from print to electronic journals, the number of users increased by 30% and the number of papers read by researchers increased by 7 times. It is also found that many of researchers do not use SD useful functions such as searching, linking to other bibliographic records, and alerting new information of electronic journals.
