Modeling the measurement of VVER-1000 reactor power by neutron and gamma radiation with MCNP code
The present study deals with a new method for measuring the power of a reactor. This method uses gamma and neutron radiation resulted from the entire reactor structure, without changing its structure (online). In terms of functionality, this method can measure the reactor power in real-time and report it instantly. In order to obtain the relationship between reactor power and gamma and neutron ...
متن کاملPrimary Loop Study of a VVER-1000 Reactor With special Focus on Coolant Mixing
In this paper a detailed model of a VVER1000 reactor pressure vessel (RPV) with the extension of simplified primary loops is presented (Loop model). The primary loop components like steam generators and pumps are modelled by the outer shapes and additional source terms for energy and momentum exchange. The RPV model part is tested without primary loops and compared with former results obtained ...
متن کاملStudy of thorium advanced fuel cycle utilization in light water reactor VVER-440
The first step in investigation of thorium fuel is evaluation of the results obtained from the spectral code for this type of fuel. The benchmark summarized by IAEA in 2003 was used for partial validation of the code HELIOS 1.9. The benchmark was focused on a comparison of the methods and basic nuclear data. Acceptable results of benchmark comparison allowed examining and comparing different ad...
متن کاملDetailed Cfx-5 Study of the Coolant Mixing within the Reactor Pressure Vessel of a Vver-1000 Reactor during a Non-symmetrical Heat-up Test
As part of the reactor dynamics activities of FZK/IRS, the qualification of a detailed 3D CFD model of a reactor pressure vessel is a key step in safety evaluations for improving predictive capabilities and acceptability of commercial CFD tools in reactor physics. The VVER-1000 Coolant Transient Benchmark, initiated by OECD, represents an excellent opportunity for validation. In this work a CFD...
متن کاملمدلسازی جریان آب جوش در مولد بخار VVER-1000
مدل عددی دو بعدی و سه بعدی مولد بخار VVER-1000 ، که در صنعت هسته‌ای کشور از آن استفاده می‌شود، در این مقاله ارایه شده است. برای مدلسازی انتقال حرارت جوشان، جوشش و میعان از روش اویلر- اویلر و در مدلسازی سه بعدی طرف ثانویه‌ی مولد بخار از یک مدل فضای متخلخل پیش از این گزارش شده توسط استوسیک و استوانوویچ برای مولد بخار VVER-440 ، استفاده شده است. مدل فضای متخلخل به این معنی است که بسته لوله‌ه...
