sUBJEGT: SUSQUEHANNA SQRT - BNL QUESTION ON RHR ANOCORE SPRAY PUMP/MOTOR OVERLOAD,
FOR: ACTION QDECISION QINFORMATION gj
REF: 1. Telecon and quick letter - Dick Hardy to JS Nokri dated 7-10-81.2. ORF E12-43 (RHR Pump/Notor).3. ORF E21-27 (Core Spray Pump/Motor).
Susquehanna ECCS pump/motor overloads were resolved through refinedanalysis as discussed in the Ref. 1 telecon and letter.
A summary of the method used in the reanalysis of the motor thrust bearingand foundation bolt overloads is provided below'.
o The calculated maximum momentary upthrust and downthrust loads thatthe RHR and CS pumo shafts imposed on the motor shafts exceeded theallowable values shown on the motor outline drawings; however, asdemonstrated with additional calculations, the loads did not exceed
'omponent capabilities. For example, the rated thrust capacitiesof the thrust bearings were found to be higher than the calculatedthrust load values. These thrust bearings are also supported bymechanical parts (end shield, guide plate, fasteners, etc.); there-
. fore, the'tresses in these mechanical parts were calculated and thestresses were found to be less than their corresponding allowablevalues. Lower endshield stress calculation sheets are attached asan example. The method, assumption detail drawings, etc., are containedin the referenced ORF.
'I
The results and the method of the above 'analyses have been independentlyverified and contained in the referenced design record files.

~ .The foundation bolt tensile stress on the RHR pump was reevaluated toresolve the overload. It was found that the method of static anddynamic load combination at the'oundation interface was excessivelyconservative. The corrected analysis (attached) showed that thecalculated stresses are less than the allowable stresses permitted inthe GE Mechanical and the Structural L'oading Criteria document(10,000 psi for bolts in concrete).

Thrust CapacityThe safe load for a Kingsbury Bearing de-
pends chiefly upon three factors: bearing size,shaft speed and oil'viscosity. An increase in anyof these factors increases the permissible loadwithout changing the thickness of the oil film.Kingsbury Bearings carry heavier loads at highthan at low speeds. The coeflicient of frictionis least when the bearing is well loaded.
Tables I, II and IIIshow rated capacities of6-shoe and 3-shoe standard Kingsbury Bearingsrespectively at various speeds. These tablesapply to both vertical and horizontal bearings.
s
They are based on a viscosity of 150 seconds.Saybolt at the inlet or oil bat% temperature.The true criterion is the minimum film thick-ness, but for convenience the ratings are ex-pressed as total loads. e ratin s are conserva-tive, and may be increased bv 10 er cent Incase o nee or even 25 per cent provided theol viscosity be increased in the same proportion.
Consult us freely about special conditions,such as loads, speeds, and bearing proportionsoutside the range given, also substantial over-loads that may seem'ecessary.

REFERENCE: Memo, G. Samstad to J.L. Thompson, "Susquehanna RecirculationSuction Valve Piping Loads", 6/15/81.
Valve Accelerations
Attachment 81 is a summary of accelerations for Loop B Suction and dischargegate valves and the 4" bypass valve plus a summary of load combination equa-tions.
Chan e of Bypass Line Material
Attachment f/2 is a letter, EB Poser (Bechtel) to J.W. Millard (GE), "Overstresson Recirculation Bypass Elbow", 5/28/81, which explains the change of materialfor our analysis.
Additional Clam on B ass Valve
Attachment lr'3 shows a clamp from the plate below the bypass valve operatorto the discharge piping. Our hardware engineer is working on the specificsof this clamp.
New Model for Suction/Dischar e Gate Valve
Attachment (J4 is the revised data sheet for both the suction and dischargegate valves.

4!',I/Dear Bill:0, fJiRefer to your letter GB-80-'23,8. In there you suggested that Bechtel ''f~ dg
rev'ew the design report substituting the stress for 304I material4'orthe 304 mterial used in the report. In this manor Bec'.".tel could
verify that the 4" recirculation dischar„-e valve bypass elbows areacceptable with the substituted material.
We have revieted your D sign Reports 22A5693, 22A5694 and 22A5695.It apcears that the 4" elbow near rode 721V on she t 308 of 22A5693,will have a stress ratio greater than one for "K~V CPV" when thesubstitute material allowable is used. Kr the telecon on 5/8/81,
'betwe n N.D. ~miss (GE), J. Thorpson (GE) and R.G. Archer (B), "cN CPI'"means functional caoability. Jeff clarified that this iiiears thatthe elbow will be stressed beyond its elastic limni.t and thereforits functioral capability can.".ot be assu e9. Jeff also stated thatsince the elbow is not overstressed in any other category, it shouldnot exceed its ulti.,ate capability and smrt le tcing. Based onthis, both GE and Bechtel agreed that this is acceptable.
As discussed in the meeting of April 24, 1981, GE is r analyzing thebypass lire because of a new bracket beirg. added to the bypass valve.Please include in your reanalysis the allowable stress for SA-403-WP-304Imaterial on the 4" elbows in the bypass lires.'Ih refore, while theoverstressed valve condition is being corrected, the elbows can alsobe analyzed with the correct material.
Please let us know if you agree with the above or if we can be ofassistance by June 1, 1981.

Response: Attachment 54 is a Calculation Package No. 58-J03A-2.which shows t'". the frequency of the most criticalmanifold suppo.=ts is greate than 80 Yz. Since the fieldmounted configuration is in the rigid range for bothseismic and hydvxiynamic loads, the test results satisfactori'yqualify the equipment for seismic and hydrodynamic loacs.

'UESTION:
What effect. does the instrument tubing from manifold-valve to the pressure transmitters have on the qualifi-cation of the pressure transmitters (P.O. NJ03A)'orseismic.and hydrodynamic loads'
~Ree once:
The size of the instrument tubes between the manifold valveand the pressure transmitter is 3/8" dia., 0.065" thick and weighs1/4 lbs/ft., including the weight of water. The length of thetubes varies between 5 1/2" to 12" and usually there are two tubes.With the peak of the RRS of 4g maximum for any frequency between1 to 100 Hz., and assuming the entire load of the tube is carriedby the transmitter, the maximum load seen by the transmitter fromthe tubes 1/2 lbs. x 4g = 2 lbs. This translates into less than0.15g on the transmitter which weighs 14 lbs. With this additionof 0.15g the maximum peak of the RRS will be 4.15g. However,fragility test on the pressure transmitter shows on the TRS ami'nimum acceleration of llg between 1 to 100 Hz. From this, itis concluded that the effect of the tubing on the dynamic qualifi-cation of pressure transmitter is insignificant.
