High energy neutron transmission analysis of dry cask storage

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Development of a novel ultrasonic temperature probe for long-term monitoring of dry cask storage systems

With the recent cancellation of the Yucca Mountain repository and the limited availability of wet storage utilities for spent nuclear fuel (SNF), more attention has been directed toward dry cask storage systems (DCSSs) for long-term storage of SNF. Consequently, more stringent guidelines have been issued for the aging management of dry storage facilities that necessitate monitoring of the condi...

Computational Fluid Dynamics Modeling Approach to Evaluate Vsc–17 Dry Storage Cask Thermal Designs

A numerical simulation of flow and heat transfer in a ventilated concrete dry storage cask system–17 (VSC–17) is performed and results compared with experimental data to assess the validity of the computational approach. The measurements of steady state temperature distributions on the cask surface, concrete surface, air flow channels, and fuel canister guide are available. Numerical simulation...

Neutron – Mirror Neutron Oscillation and Ultra High Energy Cosmic Rays

We discuss the phenomenological and astrophysical implications of neutron mirror neutron oscillation and show that the present experimental data allow an oscillation time in vacuum, τnn′ , much smaller than the neutron lifetime. Such a fast oscillation could provide a very efficient mechanism for transporting protons with super-GZK energies at very large distances provided that the CMB of mirro...
