High-Level Nuclear Wastes and the Environment: Analyses of Challenges and Engineering Strategies
World Journal of Nuclear Science and Technology, 2012, 2, 89-105 http://dx.doi.org/10.4236/wjnst.2012.23015 Published Online July 2012 (http://www.SciRP.org/journal/wjnst) High-Level Nuclear Wastes and the Environment: Analyses of Challenges and Engineering Strategies Mukhtar Ahmed Rana Physics Division, Directorate of Science, PINSTECH, Islamabad, Pakistan Email: [email protected], [email protected] Received February 11, 2012; revised April 2, 2012; accepted April 19, 2012 ABSTRACT The main objective of this paper is to analyze the current status of high-level nuclear waste disposal along with presen- tation of practical perspectives about the environmental issues involved. Present disposal designs and concepts are ana- lyzed on a scientific basis and modifications to existing designs are proposed from the perspective of environmental safety. A new concept of a chemical heat sink is introduced for the removal of heat emitted due to radioactive decay in the spent nuclear fuel or high-level radioactive waste, and thermal spikes produced by radiation in containment materi- als. Mainly, UO2 and metallic U are used as fuels in nuclear reactors. Spent nuclear fuel contains fission products and transuranium elements which would remain radioactive for 104 to 108 years. Essential concepts and engineering strate- gies for spent nuclear fuel disposal are described. Conceptual designs are described and discussed considering the long-term radiation and thermal activity of spent nuclear fuel. Notions of physical and chemical barriers to contain nu- clear waste are highlighted. A timeframe for nuclear waste disposal is proposed and time-line nuclear waste disposal plan or policy is described and discussed. -

Citizen scientists and professional astronomers in Colombia, Venezuela and Chile performed a set of simple observations of the phenomenon aimed to measure the speed of light and lunar distance. This initiative is part of the so called “Aristarchus Campaign”, a citizen astronomy project aimed to reproduce observations and measurements made by astronomers of the past. Participants in the campaign used simple astronomical instruments (binoculars or small telescopes) and other electronic gadgets (cell-phones and digital cameras) to measure occultation times and to take high resolution videos and pictures. In this paper we describe the results of the Aristarchus Campaign. -

Tidal Invariants for Compact Binaries on Quasi-Circular Orbits
Tidal invariants for compact binaries on quasi-circular orbits Sam R. Dolan,1, ∗ Patrick Nolan,2 Adrian C. Ottewill,2 Niels Warburton,2 and Barry Wardell3 1Consortium for Fundamental Physics, School of Mathematics and Statistics, University of Sheffield, Hicks Building, Hounsfield Road, Sheffield S3 7RH, United Kingdom. 2School of Mathematical Sciences and Complex & Adaptive Systems Laboratory, University College Dublin, Belfield, Dublin 4, Ireland. 3Department of Astronomy, Cornell University, Ithaca, NY 14853, USA. (Dated: September 20, 2018) We extend the gravitational self-force approach to encompass `self-interaction' tidal effects for a compact body of mass µ on a quasi-circular orbit around a black hole of mass M µ. Specifically, we define and calculate at O(µ) (conservative) shifts in the eigenvalues of the electric- and magnetic-type tidal tensors, and a (dissipative) shift in a scalar product between their eigenbases. This approach yields four gauge-invariant functions, from which one may construct other tidal quantities such as the curvature scalars and the speciality index. First, we analyze the general case of a geodesic in a regular perturbed vacuum spacetime admitting a helical Killing vector and a reflection symmetry. Next, we specialize to focus on circular orbits in the equatorial plane of Kerr spacetime at O(µ). We present accurate numerical results for the Schwarzschild case for orbital radii up to the light-ring, calculated via independent implementations in Lorenz and Regge-Wheeler gauges. We show that our results are consistent with leading-order post-Newtonian expansions, and demonstrate the existence of additional structure in the strong-field regime. We anticipate that our strong-field results will inform (e.g.) effective one-body models for the gravitational two-body problem that are invaluable in the ongoing search for gravitational waves. -
