Rev. 3 Program Description l

The Pump Preservice/ Inservice Testing Program for Byron Nuclear Power l

Station Unit 1, is implemented in accordance with the requirements of Subsection IWP of Section XI of the ASME Boiler and Pressure Vessel Code, 1980 Edition, through the Winter of 1981 Addenda. Where these requirements are determined to be impractical, specific relief is requested. Additional pump relief requests may be necessary and these will be identified during subsequent inservice tests. The pumps subject to ISI testing are those pumps which are identified in the Byron FSAR as Active, and have an emergency power source. Active pumps are defined as those which are called on to perform a safety function as well as to accomplish ard maintain a safe reactor shutdown. The only exceptions are the diesel driven auxiliary feedwater pump, (1AF01PB), and essential service water makeup pumps, (OSXO2PA, OSXO2PB), which are included in the program, although they are not supplied by an emergency power source.

Pump reference values shall be determined from the results of a preservice test, which may be run during preoperational testing, or from the results of the first inservice test run during power operation.

Reference values shall be at points of operation readily duplicated during subsequent inservice testing. Additional refererece values may be necessary and these will be taken in accordance with IWP-3111 and 3112.

In the event a pump must be declared inoperable as a result of inservice testing, limitations on plant operation will be as stated in the Technical Specifications.

Section XI of the ASME Boiler and Pressure Vessel Code shall not be construed to supersede the requirements of any Technical Specification.

Revision 3 TABLE DESCRIPTION The following informatian is included in the summary tables: ,-

The first four columns include the unique Byron Station Equipment Piece Number, the Pump Name, the Code Class, and the P & ID on which the pumps are located.

Speed :

Speed will be measured by a tachometer for variable speed drives.

Inlet pressure:

Inlet pressure will be measured via permanently installed gauges or other means, provided the equipment accuracy meets the requirements of IWP-4150. This is to be measured both before pump startup and during the test.

Differential pressure:

Differential pressures will be measured using calibrated differential pressure gauges or by recording the difference between calibrated inlet and outlet pressure gauges.

Flow rate: Flow rates will be measured using permanently installed instru-mentation or other means, provided that equipment accuracy meets the requirements of IWP-4150.

Vibration: Vibration measurement shall be made using portable or hand held instruments at locations as marked on the pumps.

l Bearing Temperature: Bearing temperature will be measured by permanently installed deviccs where such devices are present. Portable measurement devices will be used where temperature wells are provided.

Per IWP-3300, bearing temperatures are required only once per year. Byron Station takes the data for bearing temperatures once per year during summer testing.

Test Interval: An inservice test shall be run on each pump nominally every 3 months during normal plant operation, in accordance with IWP-3400.

Lubrication Level: Lubrication level will be observed through sight glasses for the pumps listed in the program.

Revision: The current revision of the program is listed.

Table Page: The table pages are numbered sequentially ard show the total number of pages.

NOTE 1 Revision 3

" Deleted" NOTE 2  :

The Diesel Oil Transfer, Residual Heat Removal and Containment Spray pumps cannot be measured for lubrication 1.svel.

hence have no indication for lubrication level.These pumps are lubricated by the fluid pumpe I

NOTE 3 g

These pumps are in a system which is in continuous operation. The idle inlet pressure, therefor e cannot be obtained.

Proper pump operation is assured by continuous parameter s. pump operation as well as quarterly monitoring of the remaining ISI pump NOTE 4 The Diesel Oil Transfer pumps are positive displacement pumps. The pump differential pressure is not a factor affecting pump performance but rather deperdent only on the inlet pressure to the pump. As the pump discharge pressure is constant, and the inlet pressure operational varies with tank level, the differential pressure is not a valid parameter.

For this reason, pump discharge pressure will be used to evaluate pump perfornance in lieu of using pump differential pressure.

Revision 3 RELIEF REQUEST NO. PR-1

1. PUMF NUMBER: All pumps in the program plari. - '
2. NUMBER OF ITEMS: 23 pumps.
3. ASME CODE CLASS: 2&3
4. ASME CODE, SECTION XI REQUIREMENTS: In r efer ence to Table IWP-3100-2,

" Allowable Ranges of Test Quantities", pump vibration is to be measured in and compared to values given in mils displacement.

5. BASIS FOR RELIEF: The measurement of pump vibration is required so that developing problems can be detected and repairs inii;iated pr for to a pump becoming inoperable. Measurement of vibration only in displacement quantitles does not take into account frequency which is also an important factor in determining the severity of the vibration.
6. ALTERNATE TESTING: The ASME Code minimum standards require measure-ment of the vibration amplitude in mils (displacement).

Byron Station proposes an alternate program of measuring vibration velocity (inches per second) which is more com-prehensive than that required by Section XI. This technique is an industry-accepted method which is much more meaningful and sensitive to small changes that are indicative of devel-l oping saechanical problems. These velocity measurements l

detect not only high amplitude vibration, that indicate a major mechanical problem, but also the equally hartriful low amplitude, high frequency vibration due to misalignment, unbalance, or bearing wear, that usually go undetected by simple displace-i ments measurements.

8-(

(0297M)

I Revision 3 The " General Machinery Vibration Severity Chart" published by IRD Mechanalysis, Inc., (see attached) will he used in place of Table IWP. 3100-2 for the Allowable vibration ranges.

The " Alert Range" will be .314 in/sec i V < .628 in/sec. The required action range will be V 2 628 in/sec. Evaluation of data, to assign equipment to the alert or action ranges, will be done within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> (per IWP-3220 of Section XI). This will be done using industry accepted vibration analysis equipment, such as a full spectrum analyzer.

7. JUSTIFICATION: Measurements of vibration in mils displacement are not sensitive to small changes that are indicative of developing mechanical problams. Therefore, the proposed alternate of measuring vibration amplitude in inches /second provides added assurance of the continued operability of the pumps.
8. APPLICABLE TIME PERIOD:

This relief is requested once per quarter during the first inspection interval.

2. NUMBER OF ITEMS: 15 pumps
3. ASME CODE CLASS: 2&3
4. ASME CODE, SECTION XI REQUIREMENTS:

Per IWP-3100, Inservice Test Procedure pump bearing temperatures are required to be measured to detect any change in the mechanical character-istics of a bearing. IWP-3500(b) requires three successive readings taken at ten minute intervals that do not vary more than 3%.

5. BASIS FOR RELIEF:
a. These pumps' bearings are not provided with permanent temperature detectors or thermal wells. Therefore, gathering data on bearing temperature is impractical, b.

The only temperature measurements possible are from the bearirr; housing. To detect high bearzng temperature at the bearing housing would require that the bearings in question be seriously degraded, c.

Measurement of housing temperature on many of these pumps does not provide information on bearing condition or degra-dation. For example, the bearings on the Essential Service Water pumps (OSXO2PA, OSX02PB) and Diesel Oil Transfer Pumps (10001PA, 10001PB, 10001PC, 10001PD) are cooled by the fluid pumped.

11-

Revision 3 Therefore, any heat generated by degraded bcarings is carried away by the cooling fluid and would not be directly measured at the bearing housing.

~

6. ALTERNATE TESTING:

No direct alternate test is proposed for bearing temperatures.

However, measurement of hydraulic parameters and vibration readings do provide a more positive method of monitoring pump condition and bearing degradation.

7. JUSTIFICATION:

By measuring pump hydraulic parameters and vibration velocity, (as described in PR-1), pump operability and the trending of mechanical degradation is assured. Also, since these parameters (i.e., Hydraulic parameters and vibration) are measured quarterly, the pump rachanical condition will be more accurately determined than would be possible by measuring bearing temperature on a yearly basis.

8. APPLICABLE TIME PERIOD:

This relief is requested once per year, during the first inspection interval.

1. PUMP NUMBER: OSXO2PA, OSXO2PB
2. NUMBER OF ITEMS: 2 pumps
3. ASME CODE CLASS: 3
4. ASME CODE, SECTION XI REQUIREMENT: Per IWP-3100, differential pressure shall be measured on all pumps that are tested.
5. BASIS FOR RELIEF: It is impractical to measure the inlet pressures of these pumps. Instrumentation for directly measuring the inlet pressure for these pumps does not exist. These pumps are vertical well type pumps which take a suction from the river screen house forebay.

6.

ALTERNATE TESTING: These pumps will be evaluated using pump discharge pressure.

Additionally, delta level across the traveling screens will be measured to assure adequate suction level.

There is differential level instrumentation provided, which indicates the difference in level between the river height and the reservoir height in inches. This delta level will be recorded in lieu of inlet pressure for the pumps.

7.

JUSTIFICATION: The level of plant safety is not affected by not tak-ing suction pressure data on vertical well type pumps.

These pumps cannot suffer from cavitation as long as their l

impellers are submersed in the pumped fluid reservoir.

Recordino the delta level across the traveling screens ensures that the pumps will be submersed in the river since no other poscible obstructions between the river aruf pump bays exist.

4. ASME CODE, SECTION XI REQUIREMENTS: Per IWP-4120, the full scale range of each instrument shall be three times the reference value or less.
5. BASIS FOR RELIEF: The full scale range of ultrasonic flowmeters, used to collect Section XI flow data, exceed three times the reference value.
6. ALTERNATE TESTING: Ultrasonic ficaneters, with digital readouts and totalizer features will be utilized to obtain Section XI flow data.

t

7. JUSTIFICATION:

Ultrasonic flowmeters provide an accurate means of measuring flowrate. They utilize a digital display whose accuracy is independent of the full scale range. In addition, use of the totalizer feature, and integrating the flow for five minutes provides an accuracy of less than i 1% of the reading. This is well within the requirements of IWP-4110, which refers to an instrument accuracy of f 2% of full scale.

8. APPLICABLE TIME PERIOD: This relief is reauested once per quarter, during the first inspection interval.

7. part-Stroke Test (Xt)

If only limited operation is practical during plant operation, the valves shall be part-stroke (Xt) exercised during plant operation and full-stroke exercised during cold shutdowns, in accordance with IW-3412 or IW-3522.

O. MAX STROKE TIME For power operated valves requiring a full stroke test (St) in order to meet the requirements of IW-3413. the maximum allowable stroke time is specified in seconds. N/A indicates that time is not a factor,affecting valve operability.

p. TEST MODE Denotes the frequency and plant condition necessary to perform a given test. The following abbreviations are used:

Normal Operation (OP) l Tests designated "Op" will be performed once every 3 months, except in those modes in which the valve is not required to be operable.

Cold Shutdown (CS)

Valves that cannot be operated during plant operation shall be full stroke exercised during cold shutdowns. Completion of cold shutdown valve testing is not a prerequisite to plant startup. Valve testings which are not completed during a cold shutdown shall be completed during subsequent cold shutdowns to meet the code specified testing frequency. In case of frequent cold shutdowns, valve testing need not be performed more often than once during any three-month period.

Reactor Refuelino (RR)

Tests with this designation will be conducted during reactor refueling outages only.

Rev. 4 NOTE I Closure of the Main Steam isolation valves. INS 001A-D. during unit operation would result in reactor trip and safety injection actuation. To avoid this transient, these valves will be partially stroked every three months. Full stroke testing will be done during Mode 4 following, or preceding cold shutdown.

per IW-3412. .

I NOTE 2 The testing of any emergency boration flowpath valves during unit operation is not practical. Stroke testing the Boric Acid injection isolation valve. ICV 8104, and check valve. ICV 8442. the RWST to CV pump suction check valve. ICV 8546. the RH to CV pump suction isolation valve. 1CV8804A. or the RWST to CV pump suction isolation valves ICV 112D.E. could result in boration of the RCS. resulting in a cooldown transient. Aligning the system in this configuration even for a short duration, is therefore, unacceptable. These valves will be strols tested during cold shutdown in accordance with IW-3412.

NOTE 3 These valves are the Main Feedwater isolation valves. IPw009A-D. and cannot be fully stroked during operation as feedwater would be terminated causing a reactor trip. They will, however, be partially stroked tested during operation as well as full stroke tested during cold shutdown per the requirements of IW-3412.

NOTE 4 Closure of these letdown and isakeup valves. ICV 112B. C. ICV 8149A-C, ICV 8105.

ICV 8106. 1CV8152 and ICV 8160 during normal unit operation would cause a loss of

  • charging flow which would result in a reactor coolant inventory transient, and possibly, a subsequent reactcr trip. These valves will be full stroke exercised durino cold shutdown as required by IW-3412.

NOTE 5 The IRH8701A.B and 1RH8702A.B are the isolation boundary between the Residual Heat Removal pumps and the Reactor Coolant System. Opening one of these valves during unit operation will leave only one valve isolating RHR from the high RCS pressure. This would place the plant in an undesirable condition. Therefore, the valves will be a full stroke tested during cold shutdown, per IW-3522.

N7fE 6 The following valves have been identified as intersystem LOCA valves. They form l a pressure boundary between the RCS and other essential components in order to protect these components from damage. These valves will be leak tested ir, accordance with the Byron Technical Specifications.

1 N'V- 4 NOTE 13 The High Head Injection Isolation Valves. ISIB801A.B. cannot be si.roke tested during unit operation. These valves isolate the CV system from the RCS. Opening them during operation would enable charging flow to pass directly into the RCS, bypassing the regenerative heat exchanger. The temperature difference of the charging flow and the ?tCS could result in damaging thermal stresses to the cold leg nozzles as well as causing a reactivity change which would, in turn, cause a plant transient. These valves will be full stroke tested during cold shutdown in accordance with IW-3412.

NOTE 14 The safety injection system SVAG (Spurious Valve Actuation Group) valves cannot be stroke tested during unit operation. These valves are required by the Technical Specifications to be de-energized in their proper positions during unit operation. Stroking them would be a violation of the Technical Specifications as well as defeating the de-energized SVAG valve principle. These valves will be stroked tested during cold shutdown when they are not required to be de-energized. This is in accordance with IW-3412.

4. ASIE Code.Section XI Requirenents:

Observation of remote position indicators once every 2 years to verify that the valve operation is accurately indicated per IW-3300.

5. Basis for Relief:

Position indication checks are required once every two years.

Historically, plants have been on a one year refueling cycle and thus, performed this test every other refueling outage. Therefore, the intent of the code appears to be that the test be executed every other refueling outage.

Byron Station. however, is on an 18 month refueling cycle.

Executing a position indication test by either coming down in power or every refueling outage is not practical. Increasing the frequency of testing in radiation areas, would increase personnel exposure by as much as 25% over plants on a two year refueling cycle.

+

6. Alternate Testing:

Position / Travel indication examinations will be performed on a frequency of outage.

approximately once every 3 years, or once every other refueling All active power operated valves (except 50V's) listed in the ISI Valve Program will be stroked timed. For valves with remote indication.

timing is done remotely. This time is then recorded in a procedure which trends the stroke time of each valve. If the maximum stroke time for the valve is exceeded, a local stroke timing of the valve will be initiated.

provided AIJutA concerns allow such a test. If the local time varies by more than 20% or 1 second, whichever is greater. from the remote time, the limit switches will be adjusted accordingly.

7. Justification:

Position indication tests executed on a frequency of once every 3 years, along with a case by case investigation of Position / Travel Indication discrepancies, will adequately maintain the system in a state of operational readiness. In addition to this, radiation exposure levels for personnel will be greatly reduced.
