4.0 BACKGROUND
IPROCESSDESCRIPTION 4.1 Reactor Recirculation Pump
Description:
The Hope Creek Reactor Recirculation pumps are ByronJackson (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.
4.2 Pump Shaft Vibration Instrumentation
Description:
Two proximityprobes (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 W E 4 ,
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.
4.3 Reactor Reclrculation Motor
Description:
The Hope Creek Reactor Recirculationpump motors are General Electric (GE) variable speed, 7500 HP motors. Vibration data is collected by a velocity meter and in the case of '6Reactor Recirculationpump motor also by five accelerometers.
4.4 Motor Radial Vibration
Description:
One Velocity meter is installed on the upper edge of the motor upper bearing bracketto detect motor radial vibration, FLOC: IllBB-1 BBVE-791OA(B)4. The vibration signal is alarmed in the control room via overhead W E 4 , "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 containsthree 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 acquisitioncabinet located in the reactor building, 102' elevation.

I Hope Creek Station installed upgraded reactor recirculationpump vibration processingand alarm equipment per Design Change Package (CP) 80077512.
CP 80077512 replaced existing Hope Creek RecirculationPumps/Motors I
vibration monitoring probes, proximeters, extension cables, and electronic equipment with new probes, proximeters, extensioncables and state-of-the-art Bently Nevada (BN) 3500 Monitoring System. The new system improvesthe 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 monitoringand provide alarms in the Control Room for necessary operator action. The new 3500 MonitoringSystem is installed in Rack C of cabinet 1BC374. Existing system equipment locatedin Rack B of cabinet 1BC374 has been removed.
The new system permits the control room operators to have continuous 1X and 2X vibration peak and associated phase angle monitoring with audible alarms.

I 5.1.2 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 recirculationpump will be at reduced speed in accordance with HC.OP-A8.RPV-O003(Q), Recirculation System.
5.1.3 The reactor recirculationpumps have resonancefrequencies 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 720-800 RPM 1040-1090 RPM
'6Reactor Recirculation Pump 700-760 RPM 1150-1200 RPM 1444-1484 RPM 5.1.4 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), OverheadAnnunciator 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.
5.1.5 The following informationis provided to assist engineering in evaluating the reactor recirculationpump and motor vibration data. The engineer performing the evaluation remains responsibleto review the overall operating conditionof the pump, and if necessary collect data outside this procedure, to determine the condition of the component.
5.1.6 Notify the Engineering Programs Manager within one hour of receiving a valid reactor recirculationpump atarm.
