The nuclear fuel performance during accidents became a critical issue after the Fukushima Daiichi nuclear accident in 2011. Currently, various research and development programs are being carried out to enhance the fuel's reliability and durability under such conditions. These programs are collectively known as the Accident Tolerant Fuel (ATF) R&D program, which involves multiple countries,...
Accurate and reliable computer codes for neutronics are essential for nuclear reactor design and operation since they permit the simulation of neutron behavior inside the reactor core. These simulations are crucial for anticipating the reactor's performance, safety, and efficiency. In order to ensure the safe operation of nuclear reactors and the advancement of new reactor technologies, the...
During daily load-follow operation, the xenon concentration in the reactor changes over time due to reactor power variation. To compensate for this change, the soluble boron concentration in the core is adjusted through dilution or boration. However, since xenon is not directly measurable in the reactor, the sliding mode observer is utilized to estimate the xenon concentration prior to the...
The discrete-ordinates-method (DOM) is one of the primary numerical techniques for the solution of the Boltzmann Transport Equation (BTE) as well as other transport equations that have been derived from the BTE. These transport equations are used for the study of various phenomenon such as the radiation heat transfer in a participating media, heat conduction via phonon transport at the...
This is a preliminary investigation of safety characteristics of the Stable Salt Reactor (SSR), which is a fast-spectrum molten salt reactor proposed by Moltex Energy. The reference Moltex fuel composition and other publicly released information have been utilized in this work. Regarding the liquid salt fuel, two more TRU (transuranics) compositions are also considered for improved core...
The fundamental energy transformation that occurs in a nuclear power plant involves converting the kinetic energy of fission process fragments into thermal energy. The reactor coolant is maintained at temperatures typically between 300-400°C, which limits the efficiency of energy conversion from thermal to mechanical and then to electrical to around 30-35%. The average energy of neutrons...
The SMART (System-integrated Modular Advanced ReacTor) reactor is a small, pressurized water reactor that utilizes integral pressurized water coolant, which offers many advantages over traditional designs. In this paper, a neutronic analysis of the SMART modular reactor fuel using the DeCART2D computer code is performed, considering annular and mixed oxide (MOX) fuel types. The study modeled...
