Evaluation of DNBR with neutronics calculation in LWR systems

چکیده
The heat flux in a Light Water Reactor (LWR) system is used to estimate the Departure from Nucleate Boiling Ratio (DNBR) of which an important thermal hydraulic parameter for nuclear reactors removal point view. DNBR signifies operational safety limit i.e. power plant has be operated with sufficient margin specified assuring its safety. evaluated using analysis code inputs neutronics calculation. present paper presents evaluation approach minimum (MDNBR) during standard calculation performed core physics and burnup variation MDNBR studied full cycle length. results are presented equilibrium 2700 MWth/900 MWe Indian Pressurized (IPWR). calculations VISWAM-TRIHEXFA system. few group lattice parametric library IPWR generated by VISWAM. follow up configuration been TRIHEXFA. A first order feedback model introduced into 3D finite difference simulation tool critical calculation, required estimation DNBR, W-3 Tong OKB-Gidropress correlations implemented

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...

The aim of the research described in this paper is to perform consistent comparative analyses of two different approaches for coupling of two-scale, two-physics phenomena in reactor core calculations. The physical phenomena of interest are the neutronics and the thermal-hydraulics core behaviors and their interactions, while the spatial scales are the “global” (assembly/channel-wise) and the “l...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
