Pressure Field Measurements in a Helical Coil Steam Generator Model Using Pressure Sensitive Paint Porter, Garland Alec (2020-05-02)Helical coil heat exchangers are types of tube and shell heat exchangers that have been implemented in processing plants, oil and gas, and refrigeration. Currently several designs have been proposed for next generation ...

Jones, Philip G (2017-12-08)The sodium fast reactor is a type of liquid metal fast breeder nuclear reactor. Fast reactors offer a number of benefits over conventional thermal reactors such as, a more abundant source of fuel, and are inherent increases ...
-
Childs, Mason Paul (2016-11-09)During a loss of coolant accident in a pressurized water reactor, borated water is injected into the core through emergency core cooling system to reduce the decay heat, remove excess reactivity, and maintain an adequate ...
-
A RANS Analysis of Pressurized Thermal Shock Phenomena in Nuclear Reactor Geometries Using Star CCM+ Mulloy Jr., John Patrick (2018-08-08)Computational fluid dynamics (CFD) simulations were conducted using Star CCM+ in order to investigate the mixing characteristics in the cold leg injection region of a pressurized water reactor (PWR) pressure vessel. Through ...

Yildiz, Mustafa Alper (2020-12-02)The helical coil steam generator (HCSG) is a specific type of shell-and-tube heat exchanger known for having a higher heat transfer coefficient than similar straight tube designs. Because of its compactness and higher heat ...
-
Hollrah, Brent P (2020-12-01)A major appeal of sodium fast reactors is their passive safety capabilities. To demonstrate this, a series of Loss of Flow WithOut Scram (LOFWOS) tests were conducted at the Fast Flux Test Facility (FFTF) under different ...
-
Salomao De Sena, Marcos (2023-06-20)The scaled Water-cooled Reactor Cavity Cooling System (WRCCS) experimental facility reproduces a passive safety feature to be implemented in Generation IV nuclear reactors. It keeps the reactor cavity and other internal ...
-
Busco, Giacomo (2020-10-14)The present work will illustrate a series of numerical studies, performed to evaluate the predictive capabilities of various turbulence modeling approaches, applied to a typical pressurized water reactor spacer grid, with ...

Neptune, Kaleb Todd (2018-08-06)In this study, the metazoan parasites of three species of freshwater turtles (the spiny softshell, Apalone spinifera, the common snapping turtle, Chelydra serpentina, and the red-eared slider, Trachemys scripta elegans) ...
-
White, Lance Leon Allen (2019-11-04)Liquid metal fast reactors often use a tightly packed triangular lattice of fuel pins that are helically wrapped with a wire spacer, enclosed in a hexagonal duct. These reactors are thought to suffer from partial or total ...
