Development Of 3-D Neutronic Kinetic Model And Control For Candu Reactors, Lingzhi Xia
Development Of 3-D Neutronic Kinetic Model And Control For Candu Reactors, Lingzhi Xia
Electronic Thesis and Dissertation Repository
The development of a three dimensional (3-D) neutronic kinetic modeling process aiming at control system design for CANadian Deuterium Uranium (CANDU) reactors is carried out in this thesis using a modal synthesis method. In this method, the reactor space-time neutron flux is synthesized by a time-weighted series of precalculated neutron flux modes. These modes are eigenfunctions of the governing neutron diffusion equation at reference steady-state operating conditions. The xenon effect has also been considered. A special attention has been paid to compare the performance of the developed 3-D model with that of a traditional coupled point kinetic model. The 3-D …
Investigation On The Benefits Of Safety Margin Improvement In Candu Nuclear Power Plant Using An Fpga-Based Shutdown System, Jingke She
Electronic Thesis and Dissertation Repository
The relationship between response time and safety margin of CANadian Deuterium Uranium (CANDU) nuclear power plant (NPP) is investigated in this thesis. Implementation of safety shutdown system using Field Programmable Gate Array (FPGA) is explored. The fast data processing capability of FPGAs shortens the response time of CANDU shutdown systems (SDS) such that the impact of accident transient can be reduced. The safety margin, which is closely related to the reactor behavior in the event of an accident, is improved as a result of such a faster shutdown process.
Theoretical analysis based on neutron dynamic theory is carried out to …
