[en] The principal program objectives for TSTA are: (1) to develop and demonstrate the fuel cycle for fusion power reactors; (2) to develop and test environmental and personnel protective systems; (3) to develop, test, and qualify equipment for tritium service; (4) to provide a final demonstration facility that could be directly copied for a D-T burning fusion machine; (5) to demonstrate long-term reliability of components; (6) to demonstrate long-term safe handling of tritium with no major releases or incidents; and (7) to investigate and evaluate the response of the fuel cycle and environmental packages to normal, off-normal, and emergency situations
