Post-Quake Status of the Kashiwazaki Kariwa Nuclear Power Station (Report #9)－ Participation in the exhibition booth for the 51st IAEA General Conference －October 2, 2007
Ver.0
Japan Nuclear Technology InstituteIn a bid to distribute accurate facts concerning the impact of the Niigata Chuetsu O-oki Earthquake
in 2007 on the Kashiwazaki-Kariwa Nuclear Power Station, and in response to a request from the Japan
Atomic Industrial Forum (JAIF), the Japan Nuclear Technology Institute set up a display anddispatched information officers for the JAIF booth at the 51th IAEA General Conference, convened inVienna from September 17.

The display covered information on the earthquake itself and associatedevents that occurred at the Kashiwazaki-Kariwa Nuclear Power Station.
The display attracted many of IAEA General Conference participants, successfully distributing
information to parties from around the world.

More specifically, keen interest was shown amongpeople from Asian countries, who enthusiastically sought further information.

Visitors showed strong

appreciation for supplementary video footage, which provided visual substantiation, not supplied inmedia reports, that the plant did not receive substantial damage.
This Report #9 outlines JANTI participation in the exhibition.
１． Exhibition period
September 17 (Mon) to 21 (Fri), 2007 (5 days) … Same as the 51st IAEA General Conference
２． Exhibition content（１） Information officers: Two JANTI staffs（２） Exhibits
・ Posters (outlining the earthquake andassociated events that occurred at theKashiwazaki-Kariwa

NuclearPowerStation)
・ Video (describing the post-quake statusof the Kashiwazaki-Kariwa Nuclear
Power Station)（３） Materials for distribution
・ Brochure (outlining the earthquake and associated events that occurred at the KashiwazakiKariwa Nuclear Power Station)

３． Situations at the exhibition booth（１） Due to the convenient location right in front of the escalator landing at the Conference venue, thebooth attracted approx. 300 visitors from around the world and distributed approx. 250 copies ofthe brochure over the five-day period.
（２） Compared to European delegates, their Asian counterparts (from China, South Korea, Vietnam,Indonesia, Thailand, Malaysia, etc.) enthusiastically asked more questions, demonstrating akeener interest in the exhibition.

Many IAEA officials across various sections also came to thedisplay, showing strong interest among IAEA bodies.
（３） Among the visitors were members of the IAEA Review Team that inspected the KashiwazakiKariwa Nuclear Power Station in August (Deputy Team Leader Antonio Godoy and Aybars
Gürpinar).
（４） The Senior Vice Minister of the Cabinet Office, Nakagawa, and other government officials also
visited the exhibition in the afternoon of Day 1.
４． Main questions and comments at the exhibition booth（１） Mr. Antonio Godoy and Mr. Aybars Gürpinar, who were the members of the IAEA Review Teamfor the Kashiwazaki-Kariwa Nuclear Power Station, commented that IAEA investigation also
formed similar views and found no serious damage.
（２） The Senior Vice Minister Nakagawa commended the power station for maintaining safe
operation despite the earthquake of such magnitude.

In a statement delivered to the General

Conference, he also followed opening words of greetings with a reference to Niigata Chuetsu
Offshore Earthquake, assuring that all the operating reactors had been shut down safely as
designed and there was no effect on the surrounding environment.
（３） In regard to the video shown at the booth, IAEA staff praised the footage for showing unaffectedparts of the power station, as previously available footage only depicted damaged sections.
（４） Concerning the leakage of radioactive substances, some commented that, although it is now clearthat the amount of leakage was negligible, the information disclosure system showed insufficientcompetence for initially denying any leakage and later correcting the information.
（５） Typical questions asked include:
・To what extent did the seismic motions, recorded in this earthquake, deviate from the design
values used for the power station?

・When was this and other plants built?

・Which companies were contracted to manufacture and build the power station?

・What were the types and amounts of radioactive substances leaked in the earthquake?

・Is the power station currently operational? When is it expected to resume its operation?

（６） Typical comments made include:・I am impressed that a reactor unit, designed and built over 20 years ago, withstood theseismic motions greater than that assumed for its construction.

・Media reports appear to have been generally overstated.
