There have been requests for remote analysis of measured data at the BL11 PLANET beamline in the Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC), but a system to perform this analysis on a regular basis has not been established. In order to meet this demand, a system for remote analysis was established using NoMachine, which is widely used as a remote desktop connection environment. This system is built on the cloud, and users can analyze data from anywhere with an Internet environment by using the NoMachine client.

In the JT-60 tokamak at JAERI, environment for remote participation is planned to be developed by concentrating experts of nuclear fusion research of another research organizations and universities distributed all over the country. We are constructing a hierarchical remote research system, which consists of remote experiment, remote analysis, and remote diagnostic. In a remote collaboration, it is important to maintain the security of the system, as well as to share the information, atmosphere and presence between the participants. For the latter purpose, we developed a video conferencing system, and a video streaming system that can deliver the images of the JT-60 control room. Furthermore, a development of the remote analysis system called "VizAnalysis" has been started. And to assist the remote analysis, we developed a web based software system called "VizSquare". In the JT-60 tokamak at JAERI, security and authentication methods on a computer network and a new communication tool are developed, and probably they will be applied to the remote participation of ITER.

From the year 2000 to 2001, the computer system located on Naka Fusion Research Establishment, Japan Atomic Energy Research Institute has been replaced. Since the main computer is the scalar parallel computer, which is about 40 times superior to the previous one, the amount of data outputted from the numerical simulations becomes much larger. In this paper, which scientific visual analysis system is more useful to extract the physical phenomena from such a large amount of data is investigated and the performance of the established visual analysis system is estimated.

For the safe and efficient decommissioning of Fukushima Daiichi Nuclear Power Station, development of in-situ remote analysis of nuclear fuel debris under extreme high radiation environment has been indispensable. Optical Fiber Coupled Laser Induced Breakdown Spectroscopy (OFC-LIBS) has been developed and performed up to delivery length about 50m. For more longer delivery length, "TILA" has been developed as a laser built-in remote LIBS probe and enable radiation hardened ultra-long remote analysis of 100m. In the presentation, performance of analysis and radiation hardness will be discussed.

Radiation resistant optical fiber based laser induced breakdown spectroscopy (Fiber LIBS) is developed for in-core and in-situ elemental analysis of debris and its activity is performed under severe environmental conditions such as high radiation field of about 10 kGy/h and under water. Long pulse laser, microwave assisted LIBS for more high sensitivity and liquid sample application are also introduced. Long-pulse laser with the pulse duration about 100 ns will be introduced to compensate the delivery power loss and/or to enhance the emission signal. microwave assisted LIBS technique coupled with simple antenna for the combination use with fiber LIBS will be under developing, and about ten times enhancement was observed under the atmosphere condition. For the application to the liquid phase sample, especially for the analysis of the polluted cooling water, the thin-sheet liquid jets will be also introduced as the convenience and high sensitive monitoring for dissolved elements of nuclear fuel debris.
