Available in PDF, EPUB and Kindle. Book excerpt: ``Physics of Radiation Effects in Crystals'' is presented in two parts. The first part covers the general background and theory of radiation effects in crystals, including the theory describing the generation of crystal lattice defects by radiation, the kinetic approach to the study of the disposition of these defects and the effects of the diffusion of these defects on alloy compositions and phases. Specific problems of current interest are treated in the second part and include anisotropic dimensional changes in x-uranium, zirconium and graphite, acceleration of thermal creep in reactor materials, and radiation damage of semiconductors and superconductors.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model for the spatial distribution of fission fragment damage in bulk crystals of copper and germanium was developed. Calculations of the energy distribution of primary knock-on atoms and of the range and energy loss of such atoms in the lattice are combined to determine the radial Frenkel defect concentration in a cylindrical fission spike. The radial strain field associated with such a defect concentration is also calculated and applied to the theory of diffraction contrast of fission tracks in the electron microscope. Several experimental studies of fission damage in bulk materials are discussed in the light of the proposed model. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Radiation damage in single crystal CsI(Tl) and polycrystal CsI was assessed by measuring the changes in radioluminescent intensity caused by successive neutron and gamma ray pulses from a TRIGA nuclear reactor. The radioluminescent intensity from the single crystal decreases within nine pulses by 30% in the near infrared range (0.7-4.5 ?m) and by 25% in the visible range (0.2-1 ?m) before staying constant. For the polycrystal CsI, the emission in the visible range decreases by 60% within 6 pulses and then remains constant, whereas no measurable emission is observed in the infrared. Finally, a heating and cooling cycle is shown to repair the damage for both crystals.

Download or read book Radiation Damage and Fission Product Release in Zirconium Nitride written by and published by . This book was released on 2005 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zirconium nitride is a material of interest to the AFCI program due to some of its particular properties, such as its high melting point, strength and thermal conductivity. It is to be used as an inert matrix or diluent with a nuclear fuel based on transuranics. As such, it must sustain not only high temperatures, but also continuous irradiation from fission and decay products. This study addresses the issues of irradiation damage and fission product retention in zirconium nitride through an assessment of defects that are produced, how they react, and how predictions can be made as to the overall lifespan of the complete nuclear fuel package. Ion irradiation experiments are a standard method for producing radiation damage to a surface for observation. Cryogenic irradiations are performed to produce the maximum accumulation of defects, while elevated temperature irradiations may be used to allow defects to migrate and react to form clusters and loops. Cross-sectional transmission electron microscopy and grazing-incidence x-ray diffractometry were used in evaluating the effects that irradiation has on the crystal structure and microstructure of the material. Other techniques were employed to evaluate physical effects, such as nanoindentation and helium release measurements. Results of the irradiations showed that, at cryogenic temperatures, ZrN withstood over 200 displacements per atom without amorphization. No significant change to the lattice or microstructure was observed. At elevated temperatures, the large amount of damage showed mobility, but did not anneal significantly. Defect clustering was possibly observed, yet the size was too small to evaluate, and bubble formation was not observed. Defects, specifically nitrogen vacancies, affect the mechanical behavior of ZrN dramatically. Current and previous work on dislocations shows a distinct change in slip plane, which is evidence of the bonding characteristics. The stacking-fault energy changes dramatically with lowered nitrogen stoichiometry, resulting in widely spaced partial dislocations in ZrN with high nitrogen vacancy concentration. The wide range of nitrogen stoichiometry in the phase field shows that ZrN may accept nitrogen defects readily. Explanations for this are suggested based upon the bonding structure of these cubic nitrides. This structure allows for a solid framework to remain on one sublattice, while at the same time allowing defects on the other sublattice. This allowance for defects allows significant damage from irradiation yet also decreases the drive for cluster growth. This is evidence that the structure will be acceptable for long-term use as a nuclear reactor fuel.

Available in PDF, EPUB and Kindle. Book excerpt: Solid State Nuclear Track Detectors is a collection of papers that covers various aspects of solid state nuclear track detectors. The book presents 130 articles that cover the concerns in the mechanisms, operations, and applications of solid state nuclear track detectors. The materials in the text are thematically grouped into three parts. The book first discusses the fundamental mechanisms, which include determination of the screening parameter from measurements of differential energy loss and atomic displacement effects from heavy ion induced coulomb explosion. Next, the selection presents articles that deal with the methodology of detectors, such as experimental track widths of low energy heavy ions in nuclear emulsion and structure of light nuclei tracks. The remaining papers cover the fields of applications, such as nuclear fusion; prospection of radioactive and fissionable minerals; dosimetry; and autoradiography. The book will be of great use to researchers and practitioners of disciplines related to nuclear science.
