Engineered waste-package conceptual design: defense high-level waste (Form 1), commercial high-level waste (Form 1), and spent fuel (Form 2) disposal in salt
This report provides conceptual waste package designs for use by the Office of Nuclear Waste Isolation (ONWI) in preparing a repository conceptual design in salt. Included are designs for the current reference waste form configurations of Defense High Level Waste, which consists of Savannah River Laboratory wastes immobilized in borosilicate glass, Commercial High Level Waste, which is a borosilicate glass waste form that results from the immobilization of commercial spent fuel reprocessing wastes, and Spent Fuel - Form 2, which consists of consolidated spent fuel rods from PWR or BWR assemblies. Reference designs are presented which are used as a baseline to evaluate design alternatives resulting from variations in the waste form configuration, the design approach, and the design data base. This broad spectrum of conceptual designs for salt has been included to provide ONWI a basis for concept comparison, an indication as to which of several package and repository design approaches are more cost effective, and guidance as to which approaches should be pursued in future design efforts. Based on available data and the analyses performed, all the concepts in this report offer technically viable approaches to the containment of the waste form for at least 1000 years and for adequate isolation of radionuclides thereafter. The reference borehole-type design is one which provides containment through the use of a titanium alloy corrosion-resistant overpack, backed with a carbon steel structural reinforcing member. An alternate borehole design is one which provides containment with an all-steel overpack which is sufficiently thick to withstand expected crushing loads and to accommodate expected corrosion. The self-shielded package approach provides containment through use of a thick section of moderately corrosion resistant ferrous alloy material. Development programs are identified that will be required to support designs during licensing.
