Theoretical And Experimental Study Of Degradation Monitoring Of Steam Generators And Heat Exchangers, Xuedong Huang

Masters Theses

The objective of this research is focused on the modeling, analysis, and experimental study of steam generator and heat exchanger degradation monitoring and fault diagnosis. Experimental and analytical studies of tube fouling are performed and the system-level degradations are monitored using data-driven modeling of heat exchanger measurements. Initially, a comprehensive literature study was made on the steam generator and heat exchanger degradation types and mechanisms, including fouling and corrosion.

Based on the mass balance, energy balance, and momentum balance and the moving-boundary method, a multi-node SIMULINK model of a U-tube steam generator (UTSG) has been developed so as to simulate …

Burnable Poison Design For The International Reactor, Innovative And Secure (Iris), Allan Benton Wollaber

Masters Theses

The purpose of this research was to create computer models to expedite the core design of the International Reactor, Innovative and Secure (IRIS), specifically, so that it may employ burnable absorbers to achieve a longer cycle length and enhanced safety while minimizing the use of soluble boron. The IRIS is a next-generation, integral pressurized water reactor (PWR) being designed by an international consortium led by Westinghouse Electric. Two series of comparison benchmarks, defined by Westinghouse, were completed to validate computer models of representative pin cell, assembly, and whole core geometries. The models were created using the collision probability code HELIOS …
