Ceramic-to-metal sealing. Final report

Description: Ceramic-to-metal sealing was accomplished by brazing a metallized alumina insulator to a Kovar (Carpenter Technology Corporation) pin and header. A braze alloy wetting evaluation and a braze joint tensile strength evaluation were completed by brazing the specimens in a hydrogen atmosphere. From these evaluations the best braze alloy and brazing cycle were selected. Twelve braze alloys were evaluated and Nicusil 3 (Western Gold and Platinum Company) braze alloy was found to have good wetting cha… more

The Ceramic Waste Form Process at Idaho National Laboratory

Description: The treatment of spent nuclear fuel for disposition using an electrometallurgical technique results in two high-level waste forms: a ceramic waste form (CWF) and a metal waste form. Reactive metal fuel constituents, including all the transuranic metals and the majority of the fission products remain in the salt as chlorides and are processed into the CWF. The solidified salt is containerized and transferred to the CWF process where it is ground in an argon atmosphere. Zeolite 4A is ground and t… more
