SAFETY DESIGN AND RADIOACTIVE-WASTE-DISPOSAL ANALYSIS FOR THE TITAN-II REVERSED-FIELD-PINCH REACTOR DESIGN

Strong emphasis was given to safety engineering in the TITAN study. In stead of an add-on safety design and analysis task, the safety activit y was incorporated into the process of design selection and integratio n at the beginning of the study. This approach was projected to enhanc e the potential of attaining the design goals of design simplicity, pa ssive safety, high availability, and low cost of electricity. The key safety feature of the TITAN-II design is the low-pressure, low-tempera ture waterpool that surrounds the fusion power core and the entire pri mary-coolant system. Detailed safety analyses were performed which sho w 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 s o that tritium or other radioactive material in the primary-coolant sy stem will not be released. Therefore, the public safety is assured by maintaining the integrity of the water pool. Since the water-pool stru cture can be considered a large-scale geometry, the TITAN-II design ca n be rated as a level-2 of safety assurance design ''large-scale passi ve safety assurance.'' The potential safety concerns are the control o f routine tritium releases and the handling of C-14 waste.
