Design of the OMEGA Laser Target Chamber Tritium Removal System

摘要: Preparations are currently underway at the OMEGA laser University of Rochester Laboratory for Laser Energetics (UR/LLE) to conduct direct drive implosion campaigns with inertial confinement fusion targets containing deuterium-tritium (DT) cryogenic ice layers. The Cryogenic Target Handling System will fill plastic high-pressure DT (150 MPa) 300 500 K, cool them down temperature (<25 K), form layer, and transport target chamber. Targets then be shot 60-beam 30-kJ laser. A tritium removal system has been designed remove from effluents associated operation chamber its diagnostic antechambers, vacuum pumping systems, insertion systems. design (TCTRS) is based on catalytic oxidation tritiated methane water (DTO), followed by immobilization DTO molecular sieves. TCTRS presented a challenge due low release limits dictated license UR/LLE. Aspen Plus, commercial software package intended simulation chemical processing systems operating steady state, was used simulate andmore » TCTRS. second package, ADSIM, sieve beds, which operate unsteady state. In this paper, we describe benefits that were realized use Plus ADSIM packages.« less
