Journal ArticleDOI
Performance Assessment for Geological Disposal of Graphite Waste Containing TRISO Particles
TL;DR: In this paper, a deterministic performance assessment for spent fuel from deep-burn modular high-temperature reactors (DBMHRs) in the proposed Yucca Mountain repository is presented.
Journal ArticleDOI
1-D modeling of radionuclide transport via heterogeneous geological formations for arbitrary length decay chains using numerical inversion of Laplace transforms
TL;DR: The Laplace-transformed analytical solution (LTAS) as discussed by the authors was proposed to solve the one-dimensional radionuclide transport equation for an arbitrary length decay-chain through an arbitrary combination of multiply frac-tured and porous transport segments subject to an arbitrary time-dependent release mode at the entrance point to the series of transport segments.
Journal ArticleDOI
UNF-ST&DARDS Unified Database and the Automatic Document Generator
TL;DR: Data currently available in the Unified Database is described; the two different methods for automatically generating reports from these data are explained; and examples of inline text, figures, and tables automatically generated using both approaches are shown.
Journal ArticleDOI
Effects of depth on transport of 129I in crystalline rock
TL;DR: In this article, a model for the transport of iodine through fractures in granitic rock has been developed by taking into account the variation of parameters with depth in order to investigate the effects of depth on repository performance.

TL;DR: An ion beam imprinting system has been developed at Lawrence Berkeley National Laboratory recently as mentioned in this paper, which is capable of producing multiple shaped ion beams simultaneously, therefore it is much more efficient to do micromachining for large volume production than conversional focused ion beam system.
