Establishment of the framework to visualize the space dose rates on the dismantling simulation system based on a digital manufacturing platform

• Establishment of the framework for the visualization of the analyzed space dose rate.
• Visualization of the dose rate for the dismantling simulation system using CAD-kernel.
• The intuitive support for the process evaluation related to the radiation exposure.

A decommissioning plan should involve a comprehensive review of the feasibility of the safety measures, economics and so on. There is a variety of information required for the review of each decommissioning phase, ranging from the conformity of the dismantling process to radioactive waste management. The space dose rate of a nuclear facility is one of the major data points that must be obtained during the early planning stage for the decommissioning of a nuclear facility. We propose the framework for the visualization of the analyzed space dose rate on the dismantling simulation system with the solid modeling method, which is generally used for a CAD (computer-aided design)-based digital manufacturing platform. The visualization module applying this framework is implemented using the suitable software framework that can directly interface with the dismantling simulation system. The framework of the visualization module is composed of a pre-processing stage for creating an optimal data-structure of the analyzed space does rates and a configuration stage for a visualization of the 3-dimensional models of dose on the dismantling simulation system. As a result, the module in the dismantling simulation system can visualize both the 3-dimensional space dose rate and radioactive equipment model in the same virtual space and provides useful information to users in real time for planning the dismantling process.
