The purpose of the test was to determine if the main coolant pump stator and bearing water temperature monitors and the "Primary Coolant Pump Noise Monitors" operate properly. The 1A, 1B and 1C pump bearing water temperature monitors operated satisfactorily. It is believed that the data for the 1D Bearing Water Temperature shown in Table I should be tabulated ad 1D stator temperature. This discrepancy is clarified in the note on Table I. The 1A and 1C pump stator temperature monitors operate satisfactorily. The 1B pump is a prototype and us not equipped with a stator thermocouple, On June 13, …

Description
The purpose of the test was to determine if the main coolant pump stator and bearing water temperature monitors and the "Primary Coolant Pump Noise Monitors" operate properly. The 1A, 1B and 1C pump bearing water temperature monitors operated satisfactorily. It is believed that the data for the 1D Bearing Water Temperature shown in Table I should be tabulated ad 1D stator temperature. This discrepancy is clarified in the note on Table I. The 1A and 1C pump stator temperature monitors operate satisfactorily. The 1B pump is a prototype and us not equipped with a stator thermocouple, On June 13, 1958, the Bearing Water Temperature alarm points were checked for all pumps and found satisfactory. The Stator Temperature alarm points were checked on pumps 1A, 1C, and 1D and found satisfactory. The Primary Coolant Pump Noise Monitors are capable of detecting both rapping and scraping noises in excess of normal operating noises of the pumps. The calibrating zero points were checked but not adjusted. The visual alarm on the 1A pump did operate during the test, and its operation has been erratic.
