River Bend Station - Unit I Docket No. 50-458 License No. NPF-47 Request for Relief from ASME Code Section XI Inservice Testing Requirements File Nos.: G9.5, G12.5.2 RBF1-98-0002 RBG4i339 Ladies and Gentlemen:  ;

Pursuant 10CFR50.55a(f)(5)(iii), River Bend Station (RBS) requests relief from certain ASME Code,Section XI, Inservice Testing (IST) requirements for the second :0-year interval which began December 1,1997. The requests for reli;f are attacled for cases where full compliance with the ASME Code,Section XI, requirements is not practical in accordance with 10CFR50.55a(f)(6)(i). Because testing in accordance with the code is not pratical, alternative testing is conducted to provide adequate assurance of the operational readiness of the affected components.

The three cases concern the following requirements:

PRR-001 ASME/ ANSI OMa-1988, Part 6, Palagraph 4.6.4(b): Pump vibration measurement 1

.VRR-001 ASME/ ANSI OMa-1988, Part 10, Paragraph 4.2.1.4: Valve stroke time measurement VRR-002 - ASME/ ANSI OMa-1988, Part 10, Paragraph 4.3.2.4(b): Valve obturator movement 99011300e9 900106 '

Paragraph 4.2.1.4.

ALTERNATE TFS11NG: No stroke time measurements will be performed. The valves will be full stroke exercise tested in accordance with ASME/ ANSI OMa 1988, Part 10. SRV tailpipe steam flow, reector vessel pressure drop, or indication on the SRV tallpipe acoustic monitor will De used to provido positive indication of valve stroke.

BASIS: The Safety Relief Valves are not equipped with direct position indicat;ng devices.

Additionally, the actual valve stroke times e" on the order of 100 mS. Use of other Indicators of valve position (i.e. acour< attors, telipipt, temperature, vessel pressurs) do not provide the aco ;uired to use the stroke times, which wouki f

l A mechanical exerciser shot be used to move the disk. The force at torque detNered i 4

F to the disk by the exerciser wlN be limited to less than 10% of the equNeierd force or 4 torque represented by the minimum emergency condibon pressure differential acting l on the disk, or to 200% of the octual observed force or torque required to perform the  !

erorcise on the veno when the veno is new and in good operating condtion, .  !

)

whi.ever is iess.

l l The force or torque required to full stroke eneroise me listed veNes to the open potition wiu be measured. s  :

i Mggi Demonstration of volve otiturator movement in accordance with Part 10, Paragraph l 4.3.2.4(b) may not provide adequate assurance of salve operational readiness for check vanes other than vacuum breakers. Measurement of the force or torque y l required to initiate movement (breakaway) may Nt be suf#clent to vertfy that the listed valves are capable of stroking to their open safety posinen. Valve binding in exooss of acceptable limits may occur at obturolor posioons beyond the point of initial ,

movement. This mode of valvo degradation would not be identitled by the procedurs  !'

spoolAed in Part 10, Paragraph 4.3.2.4(b).

i The heted valves no kmger have air actuators connected to the valves. Therefore, the .

l '

valve actuators cannot be used to perform the Code required exercise testing.

Exercising the listed volves wth tow would require using the Emergency Core Cooling System (ECCS) pumps to inject water into the reactor due to the relatively high accident 50w rates rcoulrod for fuu stroke exercising of the veNes. Additionally, the -

injecuon une nozzles at.sociated wth the Residual Hsal Removal System are not 1

og Jipped with intomal spargers. General Electric Servios information Letter 401 identines problems wth injecong water through this flow path and the potenusi i

l damage to nuoloar instrumentation or fuel assonibiles which could occur if this flow -

path were used for other than emergency conditions. For those reasons performing the Code required check volve exercise testing with tow creates a hardship without providing a compensating increase in the level of qualty or safety. .

Pari 10 sino atows check valve disassornbly at refuenng outages as an aNemative to ,

the veno obturetor movement describt d in Paragraphs 4.3.2.4(a) or (b). However, ched volve disassembly is not a proftcod altomalNo.

The inroposed allemate testing is in .coordance wth a previously approved edition of the A8ME Woller and Pressure Voi / el Code and wel provide an acceptable level of E

ALTERNATE TESTING: Vibration measurements will be taken in three orthogonal directions in a location that provides valid indica.cn of motor vibratory motion in close proximity of the upper motor bearing housing.

On the standby serue water pumps the upper measurements will be taken on a lifting lug that is integral to the motor stator housing. The lifting lug is structurally rigid and provides transmissibility of the motor vibratory motion. The vibration measurements will be taken in three orthogonal directions on the lifting lug.

On the diesel fuel oil transfer pumps the upper measurements will be taken on the motor stator housing which is rigidly connected to the motor bea ing housing. The vibration measurements will be taken in three directions on the motor stator in close proximity to the motor bearing housing, BASIS: The standby service water pump motors are totally enclosed, weather proof induction motors that are equipped with housing covers which completely enshroud the upper motor bearing housing. The housing cover precludes vibration measurements imm being taken directly on the upper bearing housing.

The diesel fuel oil transfer pt mps are also equipped with housing covers that preclude vibration measurements from being taken directly on the upper motor bearing housing.

REQU5ST FOR REL!EF PRR 001 Removing the upper motor bearing housing eovers for routine vibration readings would

[

compromise the design configuration and the operation of the pump motors. Cooling.

thermocouples and other motor sensors would be disabled. Also, the test

~

- configuration would ddfor grestry from normel configuration which would invalidate the test data obtained to prove operationalreadiness of the pump. This option is not practical.

Moddying the upper bearing housing cover to include an access port or installing vibration sensors is not preferred since these methods would change component configuration wthout a compensating increase in safety. The transmission path P,r the anomate vibration points will not attenuate the vibration response or amplMude, therefore providing equhralent data without disturbing the equipment operation or - -

design.

Therefore, the allemative testing proposed would provide adequate indication of component condition te vertfy operational readiness.

NEW PAY SCALE Attached you wi:1 find a copy of the pay scale reflecting the cost of living increase that went into effect on October 12,1997. I talked with Kathy Schmitt in Human Resources yesterday and she faxed me the cepy attached She also told me that the increase should be reflected on the check you receive on January 27th, She also advised me that payroll was in the process of calculating the retroactive pay from October 12th, She said they may have this ready for the check on January 27th, but most likely we will not see this until the check of February 10,1998, if you have any questions regarding the pay scale or the retroactive pay, please let me know.
