Engineering design of the IFMIF EVEDA reference test cell and key components

Overview of the IFMIF test facility design in IFMIF/EVEDA phase

“…During the IFMIF EVEDA phase, a reference TC design has been identified, developed, and optimized [7][8][9][10]. A cross-section exploded view of the TC is shown in Fig.…”

“…A cross-section exploded view of the TC is shown in Fig. 4 [10]. The TC is a blind hot cell, with an opening at the top and an inner dimension of 4 m × 4 m × 2.8 m (L × H × W).…”

“…The biological shielding of the TC is completed by the shielding plugs and shielding walls which provide sufficient protection to the surrounding rooms and cells [11]. The shielding plugs include an upper shielding plug (USP), a lower shielding plug (LSP), six piping and cabling plugs (PCPs), and three interface shielding plugs (ISPs) [9,10]. The complete interior surfaces of the TC are covered with stainless steel liner which provides together with the upper cover plate a vacuum tight envelop as well as a second barrier for lithium loop [10] to avoid contact between lithium and concrete in case of accidental spill.…”

“…By separating TMs with the top shielding materials, the TMs can be operated independently and open-cell testing during beam-off is possible. The quench tank from the LF is arranged below the TC and is connected with the TA through penetrations in two ISPs [9,10].…”
