TDI DIESEL ENGINE REOUIREMENTS 1

1. anges to the maintenance and surveillance programs for the TOI diesel e ines, as identified in Section 9.5.4.1 of Sucolement 4 to the Vogtle  :

El tric Generating Plant Safety Evaluation. Report, shall be subject to ~

the rovisions of 10 CFR 50.59.

The fr uency of the major engine overhauls referred to in the license conditio s below shall be consistent with Section IV.I. " Overhaul Frequency in Revision 2 of Appendix !! of the Design Review /Ouality Revalidati report which was transmitted 'by letter dated May 1,1986, from J. Geor , Owners Group, to H. Denton, NRC.

2. Connecting rod semblies shall be subjected to the following inspections at each major eng e overhaul:

a. The surfaces of e rack teeth shall be inspected for signs of fretting. If fretting has occurred, it shall be subject to an engineering evaluat1 n for appropriate corrective action.

b. All connecting-rod bo s shall be lubricated in accordance with the engine manufacturer instructions and torqued to the speciff-cations of the manufactu r. The lengths of the two cairs of bolts above the crankoin shall b measured ultrasonically pre- and post-tensioning,

c. The lengths of the two pairs o olts above the crankpin shall be etensioning and disassembly of the measured ultrasonically orior -to bolts. If bolt tension is less thAq 93% of the value at installation, the cause shall be detemined, aoorocriate corrective action shall be taken, and the interval between ch cks of bolt tension shall be re-evaluated.

inspected for thread

d. All connecting-rod bolts shall be visual damage (e.g. galling), and the two pairs o connecting rod bolts above the crank pin shall be insoected by ma netic carticle testing (MT)toverifythecontinuedabsenceofcrackkg. All washers usea with the bolts shall be examined visually for si ns of galling or cracking, and reolaced if damaged.

e. Visual inspection shall be perfonned of all externa surfaces of the link rod box to verify the absence of any signs o service induced distress. ,

f.

All of the bolt holes in the link rod box shall be inspected for thread damage (e.g., galling) or other signs of abnomalitths. .e.,

In addition, the ooit holes subject to the highest stresses 0 an the pair irrinediately above the crankoin) shall be examined wit cf aporocriate nondestructive method to verify the continued absen \

cracking. Any indications shall be recorded for engineering evaluation and appropriate corrective action. \

"' The cylinder blocks shall be subjected to the following inspections at the interval specified in the inspections:

a Cylinder blocks shall be inspected for " ligament" cracks, " stud-to-stud" cracks and " stud-to-end" cracks as defined in a report

• by Failure alysis Associates, Inc. (FaAA) entitled, " Design Review of T01 R and RV-4 Series Emergency Diesel Generator Cylinder Blocks" (Fa report no. FaAA-84-9-11.1), dated December 1984. (Note that the- AA report specifies additional inspections to be perfonned for block with "known" or " assumed" ligament cracks). The inspection interv s (i.e., frequency) shall not exceed the intervals calculated using th cumulative damage index model in the subject FaAA report.

In additi ,

the inspection method shall be consistent with or equiv-alent to t se identified in the subject FaAA report.

b. In addition t i nspections specified in the aforementioned FaAA ith "known" or " assumed" ligament cracks (as defined report, blocks 1

in the FaAA repo t) shall be inspected at each refueling outage to determine whet e or not cracks have initiated on the top surface

- exposed by the al of two or more cylinder heads. This process shall be repeated o r several refueling outages until the entire -

block too has been in oected. Liquid-cenetrant testing or a i similarly sensitive no estructive testing technique shall be used I to detect cracking, and dy current shall be used as appropriate to detennine the death o ny cracks discovered. ,

c. If inspection reveals crack in the cylinder blocks between stud holes of adjacent cylinders tud-to-stud" cracks) or " stud-to-end"

' cracks, this' condition shall b reported oromptly to the NRC staf f and the affected engine shall be considered inoperable. The engine 1 shall not be restored to "operabl " status until the proposed disposition and/or corrective acti s have been approved by the NRC staff.

4 The following air roll test shall be perfo d as specified below, except when the plant is already in an Action State nt of Technical Soccification 3/4.8.1, " Electric Power Systems A.C. Sources ':

The engines shall be rolled over with the'airsta system and with the

cylinder stoccocks open orior to each planned star . 11 unless also that start-be rolled

T detected in the cylinder must be determined and any cylinder head which eaks due to a crack shall be replaced. The above air roll test may be-continued following the first refueling outage subject to the' 1

fo owing conditions: , ,X

a. A cylinder heads are Grouc !!!' heads (i.e., cast after September 19 .

b. Qualit revalidation inspections, as identified in the Design

. Review / lity Revalidation report, have been completed for all ,

cylinder ads.

c. Group III he s continue to demonstrate leek-free oerformance.

This should be onfirmed with TDI prior to deleting air roll tests.. v

5. Periodic inspections the turbochargers shall include the followino:

bearings shall be visually inspected for

a. The turbocharger thru ,

excessive wear after 40 on-prelubed starts since the previous visual inspection.

b. Turbocharger rotor axial cle ance shal'1 be measured at each iance with TDI/Elliott refueling outage to verify c specifications. In addition, th st bearing measurements shall be- g comoared with measurements taken a viously to determine a need for , , .

further inspection or corrective ac on.

c. Spectrographic engine oil and ferrograp c engine oil (wear) analysis shall be performed quarterly to provide e ly evidence of bearing.

degradation. Particular attention shall b aid ta cooper level ,

and particulate size which could signify th 't bearing degradation.
