Dear Mr. Tucker:

Subject:

Catawba Nuclear Station, Unit 2 - Transmittal of a Preliminary Draft of the Proposed Low Power License Enclosed for your review and comment is a preliminary draft of the proposed low power license for Catawba Unit 2. A principal objective of this trans-mittal is to ensure that it accurately reflects the commitments required of Duke Power Company as described in the FSAR, SER and other documents. We expect that the_ license conditions for the low power license will be the same as those in this draft ifcense, unless a resolution is reached before issuance of the low power license.

Please provide your comments by February 4,1986. If you require any clarifi-cation of this matter, please contact the Project Manager, Kahtan Jabbour, at (301) 492-9789.

ATTACHMENT 2 TO LICENSE NPF-48 g!Q nJ1l E TDI DIESEL ENGINES REQUIREMENTS Duke Power Company shall comply with the following requirements'rdlated to the" TDI diesel engines for Catawba Unit 2.

1. . Changes to the maintenance and surveillance program for* the TDI diesel

< engines, as identified and approved by the NRC staff in Supplement 5 to the SER, shall be subject to the provisions of 10 CFR 50.59.

2. Connecting rod assembifes shall be subjected to the following inspec-tions at each major engine disassembly (approximately every 5 years):

The clearance between the link pin and the Ifnk rod should be examin0d. This dimension must be zero when the specified bolt torque is applied.

The surfaces of the rack teeth should be inspected for signs of fretting. If fretting has occurred, it should be subject to an engineering evaluation for appropriate corrective action. The mating surfaces should also be examined to ensure that the percentage of contact meets manufacturer's recommendations.

All connecting-rod bolts should be lubricated in accordance with the engine manufacturer's instructions and torqued to the speci-fications of the manufacturer (e.g.,1700 ft - lb). The lengths of the two pairs of bolts above the crankpin should be measured ultrasonically pre- and post-tensioning.

If connecting-rod bolt stretch was measured ultrasonically during reassembly following the preservice inspection, the lengths of the two pairs of bolts above the connecting rod should be remeasured ultrasonically before the link rod box is disassembled. Alternatively, the breakway torque should be -

! measured. If bolt tension detemined by either method is less than 93% of the value at installation, the cause should be detemined, appropriate corrective action should be taken, and the interval between checks of bolt torque should be reevaluated.

All connecting rod bolts should be visually inspected for thread l damage (e.g., galling), and the two pairs of connecting rod bolts above the crankpin should be MT inspected to verify the continued absence of cracking. All washers used with the bolts should be examined visually for signs of galling or cracking, and replaced

, if damaged.

A visual inspection should be performed of all extern'al surfaces of the link rod box to verify the absence of any signs 6f service induced distress.

1

. DRAFT All of the bolt holes in the link rod box should be inspected for thread damage (e.g., galling) or other signs of abnomalities. In addition, the bolt holes subject to the highest stresses (i.e., the

2- ' pair imediately above the crankpin) should be examin~ed with an appropriate nondestructive method to verify the continued absence of cracking. Any indications should be recorded for engineering-Evaluation and appropriate corrective action.
3. Cylinder blocks shall be inspected at intervals calculated using the cuculative damage index (CDI) model and using inspection methodologies described by Failure Analysis Associates, Inc., (FaAA) in report entitled " Design Review of TDI R-4 Series Emergency Diesel Generator Cylinder Blocks" (FaAA-84-9-11) dated December, 1984. Liquid penetrant inspection of.the cylinder liner landing area should be perfomed anytime liners are removed. If inspection reveals cracks in the cylinder block between stud holes of ad.iacent cylinders, this 4

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.

4. The engines shall be rolled over with the airstart system and the cylinder stopcocks open prior to any planned starts, 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. The engines shall also be rolled over with the airstart system and 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 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> after engine shutdown and then rolled over once again 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 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> periods noted above, that engine 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 cylinders must be detemined and any cylinder head which leaks due to a ~ crack shall be replaced. No cylinder heads that contain a through-wall weld repair where the repair was perfomed from one side only shall be used on the engines.
5. Periodic inspections of the turbochargers shall include the followirg:

4 The turbocharger thrust bearings should be visually inspected for excessive wear after experience 40 non-prelubed starts since the previous visual inspection.

Turbocharger rotor axial clearance should be measured at each refueling outage specifications. to verify compliance with TDI/Elliot,In addition, thrust bear be compared with measurements taken previously to deterr6fne whether trend exists. Any such trends shall be evaluated by the licensee to determine need for further inspection at corrective action.

- r-DRAFT Spectrographic and ferrographic engine oil analysis shall be performed quarterly to provide early evidence of thrust bearing degradation. Particular attention should be paid to copper level and particulate size which could signify thrust bearing

. degradation.

The nozzle ring components and inlet guide vanes should be

,- visually inspected at each refueling outage for missing parts or parts showing distress. If such are noted, the entire ring assembly should be replaced.

Pre-turbine exhaust temperature shall be monitored during engine operation to ensure that the manufacturers temperature limit is not exceeded.

6. Main bearing No. 7 of emergency diesel generator 28 shall be dis-assembled and inspected at each refueling outage, both visually and with liquid penetrant. Subsequent to reassembly and run-in testing in accordance with manufacturers recomendations, but prior to considering the engine to be operable, the No. 7 bearing cap and upper bearing shell shall be removed. Visible edges of the lower shell and the upper shell shall be visually inspected to ve_rify that the bearings are free of distress. Operation beyond the first refueling outage shall reouire staff approval based on the staff's final review of the Owners Group generic findings and of the overall implementation status of Owners Gr6up recommendations at Catawba 2.
