“…The experimental configuration for these studies was modeled after the apparatus in a recent report 3 , where dissolver solution is added into a glass reaction vessel, placed onto a hot plate-stirrer, and heated to 50-100 °C. A 75 mL dissolver solution volume was selected for dissolutions based on the available mass of Th metal, the calculated total gas production, and the minimum solution needed to completely cover the one inch square thorium coupon.…”
