We investigated Ocean sediments and seawater from inside the Fukushima exclusion zone and found radiocesium (134Cs and 137Cs) up to 800 Bq kg-1 as well as 90Sr up to 5.6 Bq kg-1. This is one of the first reports on radiostrontium in sea sediments from the Fukushima exclusion zone. Seawater exhibited contamination levels up to 5.3 Bq kg-1 radiocesium. Tap water from Tokyo from weeks after the ac...
Abstract In developing the PeLUIt 150 MW nuclear power plant based on High Temperature Gas-cooled Reactor (HTGR) technology, with helium-coolant and output thermal of MW, simulator is also developed for training operators educating other technical personnel. Referred to balance (BOP) design PeLUIt, utilized vPower simulation platform simulate secondary loop generation a water-steam Rankine cycl...
در این پروژه فیلترهای مایکرواستریپ جدیدی برای بهدست آوردن اندازهی فشرده، پاسخ تیز و نیز باند قطع عریض ارائه شده است که از جملهی آن ها فیلتری است که از سری شدن یک رزوناتور شاخهای منتهی به نیمدایره و یک تکهی شعاعی بهبود یافته به عنوان تضعیف کنندهی هارمونیک، تشکیل شده است. فرکانس قطع -3 db این فیلتر در 1.54 ghz قرار دارد. باند گذر این فیلتر تنها 0.26 ghz است که شامل محدودهی فرکانسی 1.5...
Since nuclear power plant (NPP) has lots of functions and systems, operated procedure is much complicated and the chance of human error to operate the safety systems is quite high when an accident occurs. There are two approaches to cool down the reactor coolant system (RCS) after an accident in a NPP. One is heat removal by a secondary side and the other is heat removal by a feedand-bleed (F&B...
A quenching experiment is performed to investigate the heat transfer characteristics and cooling performance of CrAl-coated Zircaloy (Zr) cladding in a water flow. The Zr one accident tolerant fuels for light reactors. uncoated also used this comparison. This simulates reflood fuel rod during loss coolant (LOCA) nuclear power plant. test conditions were determined represent peak temperature, su...
Abstract The aim of the paper is to present results and insights gained from analysis postulated severe accident scenario for Nuclear Power Plant (NPP) equipped with a VVER-1000, focusing on uncertainty assessment in prediction selected Fission Products (FPs). To this end, simulation Large Break Loss Coolant Accident (LB LOCA) along Station Blackout (SBO) was carried out. capabilities ASTECv2.2...
Background & Aim: Traffic accidents are the leading cause of death in the world, which brings great cost to the economy. So, this study aimed to determine the loss of productivity in traffic accident victims admitted to hospitals in Mashhad University of Medical Sciences in 2018. Methods: This cross-sectional study was conducted on 551 injured persons selected randomly. For productivity loss e...
