The paper deals with the thermal behaviour of a double-circuit gas insulated line inside the pilot tunnel of the future high-speed railway galleries between Italy and Austria (Brenner Basis Tunnel with acronym BBT). Since the active power losses generated by the power transmission line may likely be about 7 MW, the thermal behaviour of BBT pilot tunnel and its ventilation requirements have been evaluated by resorting to a suitable computer model. This model is based on a "control volume" approach: a discretization of the space and time domains leads to a network of thermal capacities and resistances to be solved time after time by means of a linear algebraic system.

Abstract
The paper deals with the thermal behaviour of a double-circuit gas insulated line inside the pilot tunnel of the future high-speed railway galleries between Italy and Austria (Brenner Basis Tunnel with acronym BBT). Since the active power losses generated by the power transmission line may likely be about 7 MW, the thermal behaviour of BBT pilot tunnel and its ventilation requirements have been evaluated by resorting to a suitable computer model. This model is based on a "control volume" approach: a discretization of the space and time domains leads to a network of thermal capacities and resistances to be solved time after time by means of a linear algebraic system.
