Abstract
A pump seal oil system for a reactor pump wherein seal oil is provided at a pre-determined rate of flow without changing the rate of flow in response to pressure differences between the seal oil in the pump and the reactor pressure. Seal oil is provided at a first rate when the reactor pump is in operation and at a second higher rate when the reactor pump is not in operation.
