During the summer months of 1954, the spare 190-C process pump unit was required to be placed in service for extended periods of time due to the motor winding temperatures exceeding the manufacturers recommended maximum operating limits. With nine unit operation each pump was required to supply approximately 9800 gpm to maintain the established power level of the 105-C Reactor. An operating condition requiring all process pump units to be in service simultaneously is-not desirable. Such a condition not only subjects the Reactor Unit to a possible unscheduled outage should trouble develop in any component of a pump assembly but in all probability would delay a startup of the Reactor Unit until arrangements could be completed to operate at reduced pressure in order to eliminate sustained over-heating of the pump drive motors. The purpose of this report is to summarize the activities undertaken during this investigation in order to arrive at satisfactory conclusions and recommendations for eliminate the over-heating of the related motor windings under present and proposed operating conditions.
