【 摘 要 】

Tank 46F is the current drop tank for the 2F evaporator and contains about190 inches of saltcake. Samples from the High Level Waste (HLW) Evaporator feed and drop tanks are analyzed every six months for criticality safety and scale formation potential. Analysis performed under this program includes analysis for silicon, aluminum, sodium, and free hydroxide concentration (evaluation of scale formation rates) and suite of criticality analyses . The recent minor leaks detected in Tank 5F have also led to HLW engineering to attempt to decide where to send material from Tank 5F. One of the primary options is to transfer Tank 5F material to Tank 46F. In order to support the Tank 5F transfer decision process, data is needed on the uranium isotopic distribution in the salt in Tank 46F.
