Based on the requirements of F4E organization, an experimental device HELCZA (High Energy Load Czech Assembly) was designed for high heat flux cyclic loading of plasma-facing components of the ITER reactor, primarily for testing of the full-size first wall modules and divertor inner vertical targets. This article presents a design of the HELCZA shielding frame for the divertor inner vertical targets irradiation by the electron beam with a power density of 40 MW/m2. The design includes the choice of the geometric shape of the frame, determines the frame heat load and provides thermohydraulic calculations for the frame cooling, including the determination of pressure losses.
