Full 3-D shielding calculations of the IFMIF test cell were performed using a computational scheme for coupled Monte Carlo/deterministic transport calculations that enables the use of a detailed geometry model of the test cell in the Monte Carlo calculation and is suitable, at the same time, to handle the deep penetration transport through the thick surrounding concrete walls. Calculations for the test cell cover, which includes numerous penetrations through which neutrons stream, were performed by the Monte Carlo method. The results demonstrate that the dose rate limit for work personnel access to the access/maintenance room can be safely met during IFMIF operation assuming the test modules are surrounded by a horseshoe shield and the back heavy concrete wall is no less than 250 cm thick. No work personnel access to the room above the cover will be permitted during IFMIF operation due to the strong neutron streaming through the cover penetrations.
