Abstract

Strong emphasis was given to safety engineering in the TITAN study. Instead of an add-on safety design and analysis task, the safety activity was incorporated into the process of design selection and integration at the beginning of the study. This approach was projected to enhance the potential of attaining the design goals of design simplicity, passive safety, high availability, and low cost of electricity.

The key safety feature of the TITAN-II design is the low-pressure, low-temperature waterpool that surrounds the fusion power core and the entire primary-coolant system. Detailed safety analyses were performed which show that the TITAN-II pool can contain the thermal and afterheat energy of the fusion power core and will remain at a low enough temperature so that tritium or other radioactive material in the primary-coolant system will not be released. Therefore, the public safety is assured by maintaining the integrity of the water pool. Since the water-pool structure can be considered a large-scale geometry, the TITAN-II design can be rated as a level-2 of safety assurance design “large-scale passive safety assurance.” The potential safety concerns are the control of routine tritium releases and the handling of 14C waste.
