Detailed 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 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 کاملModeling 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 کاملEvaluation of Single Failure Effects During Loss of Coolant Accidents For A VVER-440 Reactor
This paper describes the results of an analysis of loss of coolant accidents (LOCA's) for the Soviet designed, light water cooled and moderated reactors referred to as VVERs. The VVER unit selected for this analysis is designated as VvER-440 Model 213. This plant generates 440 Mwe and is of current interest since meen are now operating and additional units are in various stages of construction ...
