Section 7.3, "Maintenance / Surveillance Program" shall be sub.iect to the provisions of 10 CFR 50.59. '

The frequency of the major engine overhauls referred to in the license conditions Fotow shall be consistent with Section IV.1, "Overhaul Frecuency" in Revision 2 of Appendix II of the Design Review /Ouality Revalidation report which was transmitted by letter dated May 1,1986, from s1. George, Owners Group, to H. Denton, NPC, B. Cylinder Block The following inspection requirements are as defined in Failure Analysis Associates Inc. (FaAA) report entitled, "Design Review of TDI R-4 and RV-4 Series Erergency Diesel Generator Cylinder Blocks" (Fa AA report No. Fa AA-84-9-11.1) and dated December 1984 The inspection intervals (i.e., frequency) shall not excced the intervals calculated using the cumulative damage index model in the subject FaAA report. Liquid-penetrant testing or a similarly sensitive nondestructive testing technioue should be used to detect cracking, snd eddy current should be used as appropriate to determine the crack depth.  ;

1. EDG 101, 102 and 103 cylinder block top surface shall be '

inspected for "ligament" cracks, "stud-to-s'.ud" cracks and "stud-to-end" cracks at each major engine overhaul,

2. The licensee shall perform eddy current testing or boroscopic examination between adjacent cylinder heads after any operation of EDG 101 or 102 at areater than 1750 kW.  :

?. EDG 101 and 102 cylinder block top surface shall be partially inspected at each refueling outage to determine whether or not cracks have initiated on the top surface exposed by the ,

removal of two cylinder heads. This process should be repeated i over four refueling outages until the entire block top has been in?pected, i

Amendment No. 9

hPage2ofAttachment3) 4 If any inspection reveals cracks in the cylinder blocks between stud holes of ad.iacent cylinders ("stud-to-stud" cracks) or "stud-to-end" cracks, this condition shall be reported promptly to the NRC staff and the affected engine shall be considered inoperable. The engine shall not be restored to "operable" status until the proposed disposition and/or corrective actions have been approved by the NRC staff.

5. In addition to the above, the following license conditions are applicable during the first fuel cycle and through the first refueling outage,

a. During any period of continuous operation following automatic diesel generator initiation, the Itcensee shall perfom daily visual inspections of the area between ad,4acent cylinder heads and the general block top. The licensee shall also perfom visual inspections of the same areas under intense light during the monthly surveillance testing. This condition is applicable to EDGs 101, 102, and 103.

b. Following any loss of offsite power event which results in the dutomatic starting of any EDG, the licensee shall inspect the top surface of the block exposed by the retreval of two appropriate cylinder heads fron, each of the three EDG engines. Inspections shall be by liouid penetrant, with eddy current for any identified cracks, to detemine the presence of new cracks and the depth of any new or old cracks,

c. The licensee shall perfom a liquid penetrant and, as appropriate, UT inspection of the cylinder liner landing at any time a cylinder liner is removed for any other reason. This condition is applicable to EDGs 101, 10? and 103,

d. Examination of the block top betwece cylinder heads as reoufred by item 2 above will be performed by eddy current inspection only.

C. Cylinder Block Cam Gallery Cracks Cam gallery saddle locations nos 2 and 8 on the EDr. 101 and 102 blocks will be inspected by LILCO every three months, or after 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> of operation at or above a load of 1800 XW, whiche'er comes first. These inspections shall be perfomed from the time the E0r,s are initially placed in operation for emergency standby se'vice until the first refueling outage. Liquid penetrant examina',lons of the nos. 2 and 3 saddle locations shall be perfomed to mon'tcr the length of the cracks, followed by TSI depth gauce r.easurements of the cracks to monitor their depth.

1. EDGs 101, 107, and 103 shall not he operated at power levels greater -

than 3400 KW*, as indicated by the installed power meter in the  !

Shoreham contrni room. If an engine is operated at a power level

greater than 3400 KW, for any time (1) the engine shall be removed i from service as soon as is safely possible (2) the engine shall be i declared inoperable, and (31 the crankshaft shall be inspected in i accordance with the provisions of conditions D.4 and D.5.

2. For the first fuel cycle EDGs 101, 102, and 103 are each limited to two hours of cumulative operation at loads between 3300 and 3400 kW, in addition to the monthly surveillance tests. If this limit is 1

exceeded. (1) the engine shall be removed from service as soon as is safely possible. (2) the engine shall be declared inoperable, and [

! (3) the crankshaft shall be inspected in 6',ordance with the 1 provisions of conditions D.4 and 0.5 below, i t

3. Following the satisfactory inspections of the EDGs 101, 102 and 103 [

i crankshafts at the first refueling outage, if the E hour ** l cumulative load limit of 3300 to 3400 KW, described in D.2 above is '

exceeded, a crankshaft inspection pursuant to items 0.4 and 0.3  ?

shall be performed at the next refueling outage.

I 4 At ea:h refuelina outage, the licensee shall measure and record hot i i

and cold web deflection readings on each of the diesels.  !

I

5. At the first refueling outage, the licensee shall inspect the

, crankpin journals numbered 5, 6 and 7 and the main bearing journals

! between crankpins 5, 6 and 7, including the associated oil holes and l 4 fillets in all of these journals, using LP and ET as appropriate. l l

This condition is applicable to ED0s 101, 102 and 103. I

! [

j 6. During the second and third refueling outages, inspect the fillets  !

and oil holes of two of the three most heavily loaded crankpin journals in each cranksbaft, using liquid penetrant. Indications I found should also be evaluated with eddy current methods as

! appropriate.

7. Following the third refuelino outage, inspect the fillets and oil j holes of the (al three most heavily loaded crankpin ,iournals (Nos.

i 5, 6 end 7) and (b) the main iournals located between crankpin 1 journals 5, 6 and 7, at the refueling outage corresponding to an

! approximately five year interval between crankshaft inspections, f i  !

l Domentary transients (not exceeding 5 sec) that result from changing bus [

l loads need not be considered as an overload.  !

l  !

• • If there are multiple overload events since the previous crankshaft [

inspection, then the time criterion applies to tne total accurrulateri time i in the lead range. [

E. Cylind e Heads

1. Cylinder heads purchased as replacements will be inspected in ,

accordance with paragraphs (a) and (b) are subject to paragraph (c) ,

below. l (a) Perform an ultrasonic inspection of the firedeck of all the cylinder heads at six locations to verify that the minimum thickness requirements of .400 inch is met. The six locations are specified as follows:

(1) The first location is on the firedeck between the exhaust gas ports approximately directly between the two exhamst gas ports.

(11) The second location is approximately 11/2" from the first location in a direction toward the exhaust side of the cyli.ider head.

(iii) The third location is approximately 2" from the first location in a direction toward the intake side of the  ;

cylinder head. '

(iv) The fourth location is approximately midway between the injector port and the exhaust port on the governor side of the head.

(v) The fifth location is approximately directly between the two intake gas ports.

Ivi) The sixth location is approximately midway between the iniector and exhaust port on the flywheel side o' the head.

Cylinder heads not meetina this thickness requirement shall not be used.

(b) Perfom surface inspection (either liquid penetrant or magnetic particle) of intake and exhaust valve seats and the firedeck area between the exhaust valves to verify that they are free of unacceptable surface defects. Cylinder heads with unacceptable and irreparable surface defects shall not be used. Acceptance criteria are as specified in ASME III, paragraph NB-5350.

(c) Ascertain from shop records or otherwise whether any heads have through-wall weld repairs of the firedeck whe:te the repair is perfomed from one side only. Any such heads shall not be used.

P. Any head which leaks due to a crack shall be replaced.

3. The air roll test described below shall be performed as specified except when the plant is already in an Action Statement of Technical Specification 3/4.8.1 "E,lectric Power systems. A.C. Sources:

The licensee shall bar the engines over with the barring device and 4 roll the engines over with the airstart system, with the cylinder stopcocks open, prior to each planned start, unless that start occurs within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of a shutdown. In addition, after engine operation, the engines W 1' be barred and rolled over with the airstart system and witn the cylinder stopcocks open after 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, but no more than 8 heurs after engine shutdown and then rolled over once aoain approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after each shutdown. In the event an engine is removed from service for any reason other than the rolling over procedure prior to expiration of the 8-hour or 24-hour periods noted above, that 2rgine need not be rolled over while it is out of service. The licensee shall air roll the engine over with the stopcocks open at the time it is returned to service. The origin of any water detected in the cylinder must be determined and any cylinder head which leaks due to a crack shall be replaced. The above post operational air roll test may be discontinued following the first refueling outage subject to the followino conditions:

(a) All cylinder heads are Group !!! heads (i.e., cast after i September 1980).

! (b) Quality revalidation inspections, as requirso by El above, have heen completed for all cylinder heads.

(cl Group III heads continue to demonstrato leak free perfortnance.

This should be confirmed with TDI prio' to deletino air roll j tests.

F, Turbochargers f

1. The turbocharger thrust bearing, shall be visually inspected for excessive wear after 40 non-prelubed starts since the previous visua' inspection.

2. Turbocharoer rotor axial clearance shall be measured at each refueling outage to verify compliance with T01/Elliott specificat hns. In addition, thrust bearing measurements shall be compared with measurements taken previously to deterinine a need for further inspection or corrective action.

3. Spectrographic and #errographic engine oil analysis shall be performed quarterly to provide early evidence of bearing degradation. Particuler attention shall be paid to copper level and particulate size which could signify thrust bearing degradatier.

Amendment No. 9
