Description
Looking towards the future of fusion devices, detailed understanding of the underlying working properties is desired knowledge. Even though there are many fusion devices available and extensive operating data is being collected, computational analysis is an underlying requirement to fully understand how a fusion device will operate. Due to the extensive complexity of fusion devices a computational method must be devised that will allow for quick computational iterations while minimizing the error due to the complexity of the calculation. Large amounts of data can be computed on the structural, magnetic, nuclear, etc. and all of this information is needed to develop a true picture of how a certain environment will react. Each aspect of this information is calculated independent of each other. This can cause extensive delays when trying to build the broader picture of a fusion device because of the use of separate solution methods that require different inputs.
The nuclear analysis aspect is especially important, and much of the information found through nuclear analysis must be transferred over to other analyses. At PPPL we have developed a method to move this information from the nuclear analysis done using the Attila neutronics code to other analyses using different codes such as ANSYS. A simple single breeding blanket was used to help develop this method. The setup of a single blanket allows for quick iterations to adjust the blanket parameters while maintaining the fundamental nuclear responses. Once decisions are made from the single blanket, then the model can be scaled up to incorporate the different device shapes that will affect the overall nuclear response. This report will focus on the nuclear calculations, the results of these calculations, and the transfer of the data to different analysis programs.
