A real-time graphic simulator to monitor spent nuclear fuel dismantlement devices

Ever since the first power plant had been built in 1977, the electricity by nuclear power plants has been increased in Korea. It has been required that the spent nuclear fuels of nuclear power plants should be managed safely and therefore the technology about this should be also developed. Korea Atomic Energy Research Institute has developed the devices to manage these spent nuclear fuels. Due to high radioactivity, all these devices should be operated in a hot cell, which is a sealed room. Since these devices should be very high reliable, a real-time monitoring is necessary to check that they are working correctly. In this paper, a real-time 3 dimensional graphic simulator is proposed for the monitoring and control of the spent nuclear fuel dismantlement robots through the Internet. In order to reduce the visualization time of the devices, the abstraction of graphics data is performed. Also, simple operation information from large sensor information is extracted and an efficient message format and its communication scheme are defined to reduce the communication time over the Internet
