4.4 BACKGROUND
IPROCESS DESCRIPTION Reactor Recirculation Pump
Description:
The Hope Creek Reactor Recirculation pumps are Byron Jackson (now f lowserve) Type DVSS Size 28x28~35, vertical, single stage pumps. Vibration data is collected by two orthogonal proximity probes located on the pump coupling assembly.
Pump Shaft Vibration Instrumentation
Description:
Two proximity probes (X & Y directions), FLOC'S: HIBB-I BBVE-791OA(B)1/2, are mounted on the pump coupling assembly to detect shaft radial vibration.
The vibration signal is alarmed in the control room via overhead alarm WE4, REACTOR RECIRC PUMP VIB HI and digital points D5351D5352. The vibration signal is also indicated and alarmed in the plant computer via analog points A2601 /A2603.
Reactor Reclrculation Motor
Description:
The Hope Creek Reactor Recirculation pump motors are General Electric (GE) variable speed, 7500 HP motors. Vibration data is collected by a velocity meter and in the case of '6 Reactor Recirculation pump motor also by five accelerometers.
Motor Radial Vibration
Description:
One Velocity meter is installed on the upper edge of the motor upper bearing bracket to detect motor radial vibration, FLOC: Ill BB-1 BBVE-791OA(B)4. The vibration signal is alarmed in the control room via overhead WE4, "REACTOR RECIRC PUMP VI6 HI" and digital points D5351/05352. The vibration signal also is indicated and alarmed in the plant computer via analog points A26021A2604.
In addition, 'B' Reactor Recirculation pump motor contains three accelerometers (Horizontal, Vettical. and Axial directions) at the upper edge of the upper motor bearing bracket, and two accelerometers (Horizontal, Vertical directions) on the lower motor bearing bracket. This data is recorded in a data acquisition cabinet located in the reactor building, 102' elevation.

Hope Creek Station installed upgraded reactor recirculation pump vibration processing and alarm equipment per Design Change Package (CP) 80077512.
CP 8007751 2 replaced existing Hope Creek Recirculation Pumps/Motors vibration monitoring probes, proximeters, extension cables, and electronic equipment with new probes, proximeters, extension cables and state-of-the-art Bently Nevada (BN) 3500 Monitoring System. The new system improves the reliability, and resolves the replacement parts and service related problems.
The new system also provides additional digital wtputs to enhance the diagnostics capability of the vibration monitoring system. These pump and motor vibration sensors allow continuous monitoring and provide alarms in the Control Room for necessary operator action. The new 3500 Monitoring System is installed in Rack C of cabinet 1 BC374. Existing system equipment located in Rack B of cabinet 1 BC374 has been removed.
The new system permits the control room operators to have continuous 1 X and 2X vibration peak and associated phase angle monitoring with audible alarms.

E PSEG shall notify the NRC prior to implementing any change to this vibration monitoring procedure. This notification will provide sufficient time for the NRC to complete a review of the proposed changes prior to implementation. PO0775251 General Instructions The evaluation of potential shaft cracks is time critical. The Detailed Vibration Review of step 5.3.2.8, and recommendation to the control room must be completed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
If this procedure is used to support the control room response to overhead W E 4 REACTOR RECIRC PUMP VI6 HI, go directly to step 5.3.2:B, Detailed Vibration Data Review. The applicable recirculation pump will be at reduced speed in accordance with HC.OP-A8.RPV-O003(Q), Recirculation System.
The reactor recirculation pumps have resonance frequencies at specific operating speeds. Data collected at these speeds is erroneously high and is of no trending value. Avoid collecting data at the following pump speeds:
'A' Reactor Recirculation Pump
'6 Reactor Recirculation Pump 720-800 RPM 700-760 RPM 1150-1200 RPM 1444-1484 RPM 1040-1090 RPM Continuous monitoring of the pump and motor overall vibration levels are indicated and alarmed in the controt room. The operators have an approved procedure in place (HC.OP-AFt.ZZ-O008(Q), Overhead Annunciator Window Box Cl) with the necessary guidance in the event of elevated vibration levels.
The purpose of the data collected in this procedure is to provide guidance to engineering to evaluate the vibration data. The vibration analysis includes the evaluation of vibration peaks and phase angle shifts.
The following information is provided to assist engineering in evaluating the reactor recirculation pump and motor vibration data. The engineer performing the evaluation remains responsible to review the overall operating condition of the pump, and if necessary collect data outside this procedure, to determine the condition of the component.
Notify the Engineering Programs Manager within one hour of receiving a valid reactor recirculation pump atarm.

USER RESPONSIBLE FOR VERIFYING REVISION, STATUS AND CHANGES PRINTED 20050201 HC.ER-AP.BB-0001 (Z) 5.1.7 Reactor recirculation pump and motor conditions can change from cycle to cycle based on maintenance performed during outage periods; therefore, all vibration baseline levels will be re-evaluated after each plant startup and the baseline levels and acceptance bands revised accordingly.
If a single X or V proximity probe on the 8 reactor recirculation pump is out of service, restore probe to service within 14 days. If both X and Y proximity probes are out of service on the B reactor recirculation pump, restore a probe to service within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Notify the NRC Senior Resident Inspector if proximity probe(s) are out of service. If equipment cannot be restored to service within required time frame, notify Control Room to secure the applicable reactor recirculation pump. Ensure SAP notification is written to document the condition.
If a single X or Y proximity probe on the A reactor recirculation pump is out of service, restore probe to service within 30 days. If both X and Y proximity probes are out of service on the A reactor recirculation pump, restore a probe to service within 7 days. Nom the NRC Senior Resident Inspector if proximity probe(s) are out of service. If equipment cannot be restored to service within required time frame, contact Component Engineering to evaluate the condition.
Ensure SAP notification is written to document the condition.
