![]() ![]() The purpose of this paper is to summarize briefly the distribution and geologic characteristics of basaltic volcanism in the Yucca Mountain region during the last 10-12 Ma. International Nuclear Information System (INIS) These phases usually occur as members of multi-phase assemblages which are required for the incorporation of the wide variety of radionuclide elements present in the waste and the non-radioactive components added during reprocessing and pretreatment.Basaltic volcanic episodes of the Yucca Mountain region Synroc, tailored ceramics, and supercalcine, have concentrated on phases which are major constituents in the formulations: zirconolite, pyrochlore, hollandite, perovskite and zircon. Previous studies of ceramic crystalline waste forms, e.g. ![]() Authors: Haaker, R F Ewing, R C Publication Date: Research Org.: Battelle Pacific Northwest Labs., Richland, WA (United States) OSTI Identifier: 6484307 Report Number(s): PNL-3505 TRN: 81-009135 DOE Contract Number: AC06-76RL01830 Resource Type: Technical Report Country of Publication: United States Language: English Subject: 12 MANAGEMENT OF RADIOACTIVE AND NON-RADIOACTIVE WASTES FROM NUCLEAR FACILITIES 58 GEOSCIENCES APATITES CRYSTAL STRUCTURE GEOCHEMISTRY PHASE DIAGRAMS RADIATION EFFECTS BADDELEYITE HEMATITE MINERALS MONAZITES PEROVSKITE SPINELS URANINITES NATURAL OCCURRENCE ACTINIDE COMPOUNDS ALKALINE EARTH METAL COMPOUNDS ALUMINIUM COMPOUNDS ALUMINIUM OXIDES CALCIUM COMPOUNDS CALCIUM OXIDES CHALCOGENIDES CHEMISTRY DIAGRAMS HAFNIUM COMPOUNDS HAFNIUM OXIDES IRON COMPOUNDS IRON ORES IRON OXIDES MAGNESIUM COMPOUNDS MAGNESIUM OXIDES MATERIALS ORES OXIDES OXYGEN COMPOUNDS PEROVSKITES PHOSPHATES PHOSPHORUS COMPOUNDS RADIOACTIVE MATERIALS RADIOACTIVE MINERALS RARE EARTH COMPOUNDS THORIUM COMPOUNDS THORIUM MINERALS THORIUM PHOSPHATES TITANIUM COMPOUNDS TITANIUM OXIDES TRANSITION ELEMENT COMPOUNDS URANIUM MINERALS ZIRCONIUM COMPOUNDS ZIRCONIUM OXIDES 052001* - Nuclear Fuels- Waste Processing 580400 - Geochemistry- (-1989) ![]()
