§ PSEG Nuclear LLC U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 RESTART READINESS HOPE CREEK GENERATING STATION FACILITY OPERATING LICENSE NPF-57 DOCKET NO.60-354 This letter forwards Hope Creek Procedure HC.ER-AP.BB-0001 (Z) Rev. 0 Reactor Recirculation Pumps/Motors Vibration Monitoring, as requested by the NRC staff.
This procedure provides for monitoring of the vibration information available for 'A' & 'B' Reactor Recirculation pumps and motojr~s for the following purposes:
Trend the general condition of the reactor recirculation pumps and motors.
Provide an early warning of possible reactor recirculation pump shaft cracking.
Provide guidelines for gathering vibration data on reactor recirculation pumps, evaluating the data, and determining any required actions to address the condition.
Adjust acceptance criteria as pump baselines change.
In addition draft copies of the following procedures, which are being changed as a result of the installation of the new predictive vibration monitoring equipment, are included:

IPROCESS DESCRIPTION 4.1 Reactor Recirculation Pump
Description:
The Hope Creek Reactor Recirculation pumps are Byron-Jackson (now Flowserve) Type DVSS Size 28x28x35, 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 proximity probes (X &Ydirections), FLOC's: H1BB-1IBBVE-7910A(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 CI-E4, REACTOR RECIRC PUMP VIB HI and digital points D5351/D5352. The vibration signal is also indicated and alarmed in the plant computer via analog points A2601/A2603.
4.3 Reactor Recirculation 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 'B' Reactor Recirculation pump 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 bracket to detect motor radial vibration, FLOC: HIBB.-IBBVE-7910A(B)4. The vibration signal is alarmed in the control room via overhead Cl-E4, "REACTOR RECIRC PUMP VIB HlW and digital points D5351/D5352. The vibration signal also is indicated and alarmed in the plant computer via analog points A2602/A2604.
In addition, 'B' Reactor Recirculation pump motor contains three accelerometers (Horizontal, Vertical, 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.

HC.ER-AP.BB-0001 (Z) 4.5 Continuous Pump Vibration Spectrum Monitoring System:
Hope Creek Station is currently installing upgraded reactor recirculation pump vibration processing and alarm equipment per Design Change Package (CP) 80077512.
CP 80077512 replaces 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 will improve the reliability, and resolve the replacement parts and service related problems.
The new system will also provide additional digital outputs to enhance the diagnostics capability of the vibration monitoring system. These pump and motor vibration sensors will allow continuous monitoring and provide alarms in the Control Room for necessary operator action. The new 3500 Monitoring System will be installed in Rack C of cabinet 1 BC374. Existing system equipment located in Rack B of cabinet 1 BC374 will be removed.
The new system will permit the control room operators to have continuous 1X and 2X vibration peak and associated phase angle monitoring with audible alarms.

5.1.2 If this procedure is used to support the control room response to overhead C1-E4 REACTOR RECIRC PUMP VIB 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-AB.RPV-0003(Q), Recirculation System.
5.1.3 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 720-800 RPM 1040-1090 RPM
'B' Reactor 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 control room. The operators have an approved procedure in place (HC.OP-AR.ZZ-0008(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.
5.1.5 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.
5.1.6 Notify the Engineering Programs Manager within one hour of receiving a valid reactor recirculation pump alarm.
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.

RECIRCULATION SYSTEM CAUTIONS:
- 1. With the operable loop drive flow near 23 Kgpm (z48% Pump Speed), the flow through the idle loop is close to zero and will swap back and forth between forward and reverse flow. Operation in this region can cause excessive Jet Pump vibration and the potential for consequent stress fatigue of the riser brace welds to the vessel.
Operation near this value should be minimized.
NOTES:
- 1. Core Flow > 40% during single loop operation prevents excessive cool down of the idle loop.

These oscillations are a result of inherent instabilities in the Recirc Speed Control System and cannot be tuned out. Operations at these speeds may result in speed oscillations of 4 -10%. Operation at these speeds should be minimized and may not warrant actions lAW with this procedure.
