[The Waste Package Project. Final report, July 1, 1995--February 27, 1996]: Volume 2, Experimental verification of structural response of a flexible three-link hydraulic steel robot

This report presents experimental techniques for determining the static and dynamic response, in three dimensional space, of a flexible three-link hydraulic steel robot. The flexible robot was originally built under a grant from the Army Research Office (ARO) and has been the subject of a six year research project involving 12 graduate students and four faculty members. The research was continued under grant from the U.S. Department of Energy which is considering the use of robot in remote handling, placement and retrievability of H.L.N.W. canisters in geological formations. A series of static and dynamic experiments was conducted under two different loads at various angular positions of the robot links

The Waste Package Project. Final report, July 1, 1995--February 27, 1996: Volume 1, The structural performance of the shell and fuel rods of a high level nuclear waste container

This dissertation proposal covers research work that started in the spring of 1992. The aim of the research has been to study the structural performance and stability of proposed nuclear waste containers and the enclosed fuel rods to be used in the long term storage of High Level Nuclear Waste (HLNW). This research is in two phases, computational and experimental. The computational phase deals with the linear and nonlinear Finite Element Analysis of the different containers due to various loading conditions during normal handling conditions and due to the effect of long term corrosion while the canister is stored in the drift of a backfilled geological repository. The elastoplastic stability of the nuclear fuel rods were studied under body forces resulting from acceleration vectors at varying angles, resulting from a sudden drop of the canister at an angle onto a hard surface
