A Study Of An Unintentional Shutdown (Scram) Problem In The Operation Of The High Flux Isotope Reactor, Cheng Ping Wu May 1970

A Study Of An Unintentional Shutdown (Scram) Problem In The Operation Of The High Flux Isotope Reactor, Cheng Ping Wu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory experiences occasional operating difficulties caused by temporary low voltage conditions on its main power feeder line. The low voltage causes the shutdown of one or more of the three primary coolant pumps. When two of these pumps are shut down, the capacity of the cooling system is reduced to the point where the reactor is scrammed due to a high inlet coolant temperature.

This study was made to determine the cause of the high inlet temperature when operating with one primary coolant pump and to suggest possible changes …


Electronic Analog Computer Hydrologic Simulation Of The Upper Bear River Basin, Mohammed A. Basha May 1970

Electronic Analog Computer Hydrologic Simulation Of The Upper Bear River Basin, Mohammed A. Basha

OF the total precipitation falling on watersheds throughout the world, an average of approximately 85 percent returns directly to the atmosphere through evaporation and use by mountain vegetation. The remaining 15 percent moves from the watersheds as runoff and becomes available in the valleys to be used by man for irrigation, industry, recreation, and many other requirements in recent years has led to an increasing need for efficient management of available water resources, and in this regard computer modeling or simulation has proved to be a powerful tool.

The study described herein involves simulation of the hydrologic system of the …
