Release properties of UCx and molten U targets

Abstract

The release properties of UC x and molten U thick targets associated with a Nier-Bernas ion source have been studied. Two experimental methods are used to extract the release time. Results are presented and discussed for Kr, Cd, I and Xe. PACS: 29.25.Rm, 25.85.Ec, 29.30.Kv

Production of medium-mass neutron-rich nuclei in reactions induced byXe136projectiles at 1AGeV on a beryllium target

“…In the case of ISOL facilities, the main technical difference affecting spallation reactions induced on a thick 238 U target, is the extraction efficiency from the target. In principle, uranium composites present good release properties [43]. However, as already mentioned, the refractory nature of the elements of interest results in extremely low extraction efficiencies [44,45,46].…”

Investigations on the thermal release of iodine from liquid eutectic lead-bismuth alloy

“…The distribution of iodine between liquid metal and gas phase in a liquid bismuth loop has been determined under helium atmosphere at 773 K [4]. The release of iodine from liquid lanthanum and uranium in ISOL targets has been studied [5][6][7][8]. Iodine release from liquid sodium was investigated in connection with LMFBR technology [9,10].…”

UCX TARGET DESIGN FOR THE SPIRAL 2 PROJECT AND THE ALTO PROJECT

“…Assuming that the predominant release mechanism is effusion in case of tin and diffusion in case of xenon, the measurement and the analysis have been carried out as indicated in refs. [6,7]. Preliminary results indicate T R ≈ 40 s for tin and T R ≈ 20 s for xenon.…”
