Direct ultimate disposal of nuclear fuels from research reactors (joint NUKEM/GNS project). Final report

Creators

Description

42 German research reactors and the HFR Petten (MTR, TRIGA, SUR, zero power reactors, critical assemblies) were considered. Basic data of spent nuclear fuel from operational and planned reactors (27), and waste management degree and disposal of spent nuclear fuel of 16 decommissioned reactors are described. As reference fuel element (BE) the MTR standard BE was defined. The feasibility, in principle, of conditioning spent MTR-BE in the pilot conditioning plant at Gorleben (PKA) is shown. Packaging in three different repository containers is considered. The technical concepts of direct ultimate disposal can be applied to repository emplacement. Substantial planning documents are indicated, and safety-related considerations on MTR-BE in the repository described. (HP)

Abstract (German)

Betrachtet wurden 42 deutsche Forschungsreaktoren und der HFR Petten (MTR, TRIGA, SUR, Nulleistungsreaktoren, kritische Anordnungen). Basisdaten ausgedienten Kernbrennstoffs von in Betrieb befindlichen und geplanten Reaktoren (27) und Entsorgunsgrad und Verbleib des entsorgten Kernbrennstoffs von 16 stillgelegten Reaktoren sind dargestellt. Als Referenz-Brennelement (BE) wurde das MTR-Standard-BE festgelegt. Die prinzipielle Machbarkeit der Konditionierung ausgedienter MTR-BE in der Pilot-Konditionierungsanlage Gorleben (PKA) wird aufgezeigt. Betrachtet wird die Verpackung in 3 unterschiedlichen Endlagerbehaeltern. Fuer die Einlagerung im Endlager koennen die technischen Konzepte zur Direkten Endlagerung uebertragen werden. Wesentliche Planungsunterlagen sind angegeben und sicherheitstechnische Ueberlegungen zu MTR-BE im Endlager werden beschrieben. (HP)
