Noble gas monitoring at the Takasaki radionuclide station of JAEA; Certification by the Comprehensive Nuclear-Test-Ban Treaty (CTBT) Organization

Yamamoto, Yoichi

Isotope News, (736), p.31 - 33, 2015/08

The Takasaki radionuclide (RN) station for the Comprehensive Nuclear-Test-Ban Treaty (CTBT) has been in operation for monitoring of radioactive noble gases (radioxenon) by the Japan Atomic Energy Agency (JAEA) since 2007, first as a test run prior to receiving the certification. The noble gas system in the station was certified by the CTBT Organization (CTBTO) on December 19, 2014. Monitoring of radioxenon is expected to have a particularly valuable role in detection of an underground nuclear test. The Takasaki RN station detected radioxenon isotopes simultaneously with radioactive concentration exceeding normal background range in April, 2013. This abnormal event was identified as being associated with the nuclear test declared by North Korea in February, 2013. Since the Takasaki RN station is located at the east end of Asia, it is receiving widespread international attention as the station for radionuclides dispersed by the westerlies.

Virtual laboratory environment construction by ITBL project

Maesako, Hiroshi*; Suzuki, Yoshio; Aoyagi, Tetsuo; Nakajima, Norihiro

Fujitsu, 55(2), p.109 - 115, 2004/03

ITBL (Information Technology Based Laboratory) project is promoted under the "e-Japan national priority program" by six research institutions. The project aims to construct a virtual laboratory which aid collaborative studies amongst researchers by allowing for sharing of intellectual properties and resources such as supercomputer hardware, software, data, etc. In order to realize this virtual laboratory environment, the Japan Atomic Energy Research Institute is developing an ITBL system infrastructure software system. Some of the highlighted functions offered by the ITBL infrastructure are: authentication for connecting to the supercomputers, parallel and distributed communication, job execution on the connected supercomputers, and formation of communities for aiding communication amongst researchers. In this passage, besides the introduction of the ITBL infrastructure, a brief introduction of the Quantum Bioinformatics and the Numerical Environmental Systems will be given as examples of the applications developed on the ITBL infrastructure.

A Consideration about application/report systems to be used in digital certification and the certificate authority

Abe, Shinya; Nakata, Yutaka; Iitsuka, Tomoaki; Yamagishi, Kojiro*

JAERI-Tech 2002-072, 142 Pages, 2002/10

JAERI-Tech-2002-072.pdf:17.05MB

In promoting the E-japan project (Electronic Government Policy) at JAERI, the following related activities were investigated: the national project, several social and ministry's plans, some foreign national cases and some japanese private enterprise's activities, etc. Office of IT Promotion in JAERI, getting along with the E-japan project, examined the policies to modify the current application/report system into the system based on digital certification and the Certificate Authority. These extensive investigations are described in this report.
