ATTACHMENT 2 TO NPF-58 TRANSAMERICA DELAVAL, INC. (TDI) DIESEL ENGINE RE0UIREMENlS CEICO shall com' ply with the following requirements related to the TDI diesel engines:
1.
Changes to the maintenance and surveillance program for the TDI diesel engines, as identified and approved by the NRC staff h
lemental safety evaluation report in the letter dated ";n.ba 5 4983, shall be subject to the provisions of 10 CFR 50.59, r
Aly 8, B86 2.
Crankshafts shall be inspected as follows:
The oil holes and fillets of the three main bearing journals subject to the highest torsional stresses (Nos. 4, 6, 8) shall be examined with fluorescent liquid penetrant and, as necessary, eddy current, during the one-time 5 year and each 10 year major disassembly. The same inspections on oil holes and fillets shall be performed on at least three crankpin journals between journals 3 and 8.
3.
Cylinder blocks shall be inspected at intervals calculated using the cumulative damage index (CDI) model and using inspection methodol-ogies described by Failure Analysis Associates, Inc., (FaAA) in the 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 shall be performed any time liners are removed.
- 4. 0The engines shall be rolled over with the airstart system and the cylinder stopcocks open prior to@tiutdown. 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 s 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 s
[
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 l
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 determined and any cylinder head which leaks due to a crack shall be replaced. No cylinder heads that contain a through-wall weld repair c
where the repair was performed from one side only shall be used on o
the engines.
5.
If inspection of either TDI engine reveals cracks in the crankshaft
- b or in the cylinder block between stud holes of adjacent cylinders, bb this condition shall be reported promptly to the NRC staff and the affected engine (s) shall be considered inoperable. The engines shall U
not be restored to " operable" status until the proposed disposition l
go and/or corrective actions have been approved by the flRC staff.

The following air roll tests shall be performed as specified below, except o a-that air rolls shall not be performed on an operable TDI Standby Diesel k
I if the other TDI Standby Diesel is already inoperable:
