[en] Many scoping type thermal/hydraulic and structural calculations have been performed for the TFTR component conceptual designs. Five analyses are still applicable to the current October conceptual design. The analyses are for the vacuum vessel wall temperature, neutral beam calorimeter thermal response, the discharge time of the tritium line, estimate of air leakage in the TFTR Test Cell, and maximum allowable TF coil temperature. The methods of analysis and the results are presented in this report
