ABSTRACT
TFTR test cell has a major penetration that exists on the
inner side of the north-west corner of the test cell wall.
There is no known direct line of sight from the plasma
source to the door. The biological doses were measured at
various locations inside both the legs of the labyrinth. in
addition to, scattered locations on outer segments of the
labyrinth facing the TFTR D-T plasma. In addition, six sets
of activation foil detectors were placed covering the south-
to-north leg, labyrinth entrance, and west-to-east leg. The
doses have been calculated using 3-D monte carlo code
MCNP with ENDFB-VI. The calculations reprloduce the
