Patent number: 8675806
Abstract: Example embodiments relate to a method and apparatus for reducing electrostatic deposition of charged particles on wetted surfaces that are exposed, periodically or substantially continuously, to high velocity fluid flow within a coolant flow path in a nuclear reactor. The method may include depositing a first or base dielectric layer and a second or outer dielectric layer on a conductive surface that forms a portion of a high velocity flow path to attain the apparatus. The first dielectric layer material is selected to provide improved adhesion and insulation to the conductive surface and the second dielectric layer material is selected to provide suitable adhesion to the first dielectric layer and improved corrosion and/or mechanical resistance in the anticipated operating environment.

Patent number: 8676387
Abstract: Embodiments of methods and systems for monitoring of pumps are provided. According to one embodiment of the invention, there is disclosed a method for determining operating states of pumps. The method may include receiving, by a controller from a first sensor communicating with a first pump, a first vibration measurement. Further, the method may include receiving, by the controller from a second sensor communicating with a second pump, a second vibration measurement. Operating states of the first pump and the second pump may be thus determined based at least in part on comparing the first vibration measurement to a first operating condition and comparing the second vibration measurement to a second operating condition. A control action may be transmitted responsive to determining the respective operating states of the first pump and the second pump.
