A study on shielding problems of the International Thermonuclear Experimental Reactor (ITER) is presented. Considerable effort was spent on the design of the blanket and shield of ITER during Conceptual Design Activities (CDA) Phase of work. However, many problems of shielding are to be solved during Engineering Design Activities (EDA) Phase of work. The study has been performed to solve some ITER shielding problems and to rise up others which are to be solved. The present study is composed of four parts, each of which dedicated to a group of common problems which are a greater concern in terms of shielding performance. These group are the inboard ITER shield problems, outboard ITER shield problems, top/bottom ITER shield problems and shielding recommendations in connection with the ITER maintenance. Most of problems were solved analytically by extrapolations of previous results of neutron transport calculations on the design elaborated in Japan after the CDA. The problem of neutron streaming through the ITER divertor piping was solved by carrying out neutron transport calculations for the two-dimensional DOT3.5 code. (author).
