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...

In this paper, the conceptual design and a preliminary study of LUT Heating Experimental Reactor (LUTHER) for 2 MWth power are presented. Additionally, commercially sized designs 24 120 powers briefly discussed. LUTHER is scalable light-water pressure-channel reactor designed to operate at low temperature, pressure, core density. The utilizes enriched uranium (LEU) produce low-temperature outpu...

Computational processmodels in combinationwith innovative designmethodologies provide a powerful reactor design platform. Yet, model-based design is mostly done in a pure deterministic way. Possible uncertainties of the underlying model parameters, prediction errors due to simplifying assumptions regarding the reactor behavior and suboptimal realizations of the design along the reaction coordin...

This paper presents a comparative study of different control design methods applied to a nuclear reactor model. A nuclear reactor temperature controller is designed using the H-infinity (H∞) control. This advanced controller is compared with a conventional Proportional–Integral–Derivative controller (PID) controller and a traditional optimal controller design using Linear Quadratic Gaussian (LQ...

The Advanced Liquid Metal Reactor (ALMR) Actinide Recycle System is being developed in the United States for application early in the 21st century. The ALMR is a major part of this system and has missions beginning with near-term (10 years), medium term (15-20 years), and long-term (beyond 20 years) horizons. These missions use the same reactor design with modifications only to the reactor core...

Torrefaction is a thermochemical process, where biomass obtained in temperature range from 200 to 300 °C, inert atmosphere with the aim increase carbon content of biomass. In this paper, emphasis on feedstock types, different effects torrefaction success, and reactors.

The basic structure of a reactor physics laboratory environment simulation software, developed using object modeling technique (OMT), and based on the reactor point kinetic equation, is presented. Also, various capabilities of the simulator in teaching the fundamental concepts of reactor physics are discussed. In this virtual laboratory, student can perform seven different experiments, ...
