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 …
