Pressurized Water Reactor Modelling with Modelica
نویسندگان
چکیده
In order to optimize and validate the design and the operation of its nuclear power plants facilities, EDF (Electricité de France) uses a proprietary tool called LEDA to perform static and dynamic simulation at the system level. EDF wishes to replace LEDA by state-of-the-art off-the-shelf tools, mainly to reduce maintenance cost while keeping up with the latest trend in modeling and simulation technology. To validate the feasibility of replacing LEDA by Modelica based tools, several benchmarks models have been chosen, that represent the variety of engineering studies made at EDF. The objective of this work is to show that these tools are fit to dynamic modeling and simulation of a PWR plant. To that end, a reference LEDA model of such plant has been successfully translated into Modelica and simulated using Dymola. The results of the Dymola simulation experiments are compared to those obtained with LEDA. This paper describes the structure of the Modelica model, and the modeling and the numerical difficulties encountered during the translation and simulation process.

Thermal-Hydraulics analysis of pressurized water reactor core by using single heated channel model
Thermal hydraulics of nuclear reactor as a basis of reactor safety has a very important role in reactor design and control. The thermal-hydraulic analysis provides input data to the reactor-physics analysis, whereas the latter gives information about the distribution of heat sources, which is needed to perform the thermal-hydraulic analysis. In this study single heated channel model as a very f...

The modified out-in fuel management strategy was applied to the core loading design for the first four cycles of the Bushehr (Iran-1) KWU designed Pressurized Water Reactor (PWR). The minimum peak-to-average power density was chosen as the objective function of the optimization process. Lattice homogenization and group constants generation were performed by using the LEOPARD computer code. For ...
متن کاملPressurized hydrogenotrophic denitrification reactor for small water systems.
The implementation of hydrogenotrophic denitrification is limited due to safety concerns, poor H2 utilization and low solubility of H2 gas with the resulting low transfer rate. The current paper presents the main research work conducted on a pressurized hydrogenotrophic reactor for denitrification that was recently developed. The reactor is based on a new concept suggesting that a gas-liquid eq...
