TRANSAMERICA DELAVAL, INC. (TDI) DIESEL ENGINE REQUIREMENTS CEICO shall comply with the following requirenents related to the T deisel engines.
i 1.
Changes to the maintenance and surveillance program for the TDI diesel engines, as identified and approved by the NRC taff in the supplemental safety evaluation report in the letter ted July 8, 1986, shall be subject to the provisions of 10 CFR 0.59.
2.
Crankshafts shall be inspected as follows:
f The oil holes and fillets of the three main be ring journals subject to the highest torsional stresses (Nos. 6, 6, 8) shall be examined with fluorescent liquid penetrant and, as n essary, eddy current, during the one-time 5 year and each 10 year major disassembly. The same inspections on oil holes and fillets hall be perfomed on at least three crankpin journals between jo rnals 3 and 8.
3.
Cylinder blocks shall be inspected at ntervals calculated using the cumulative damage index (CDI) model d using inspection methodologies described by Failure Analysis Assoc'ates, Inc., (FaAA) in the report entitled " Design Review of TDI R-4 eries Emergency Diesel Generator Cylinder Blocks" (FaAA-84-9-ll) ' ted December 1984. Liquid penetrant
= inspection of the cylinder line landing area shall be performed any time liners are removed.
4.
The following air roll tests shall be performed as specified below, i
except that air rolls shal not be performed on an operable TDI I
Standby Diesel. if the oth TDI Standby Diesel is already inoperable:
The engines shall be ro ed over with the airstart system and the cylinder stopcocks op prior to planned starts, unless that start i
occurs within 4 hour4.62963e-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 airst t 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 mo e than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> af ter engine shutdown and then rolled over once again a proximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after each stutdown.
In the event an engine s removed fron service for any reason other than the rolling over pr cedure 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 bove, that engine need not be rolled over while it is out of servi The licensee shall air roll the engine over with the-stopcocks o en at the time it is returned to service. The origin of any water etected in the cylinders must be determined and any cylinder head whi leaks due to a crack shall be replaced. No cylinder heads that co ain a through-wall weld repair where the repair was perfonned from o e side only shall be used on the engines.
5.
If i spection of either TDI engine reveals cracks in the crankshaf t or in he cylinder block between stud holes of adjacent cylinders, this c dition shall be reported promptly to the NRC staff and the affected ngine(s) shall be considered inoperable.
The engines shall not be restored to " operable" status until the proposed disposition and/or corrective actions have been approved by the NRC staff.
ment No.
l PY-CEI/NRR-1927L Page 1 of 2 SIGNIFICANT HAZARDS CONSIDERATION The standards used to arrive at a determination that a request for amendment involves no significant hazards considerations are included in the Commission's Regulations, 10 CFR 50.92, which state that the operation of a facility in accordance with the proposed amendment vould not (1) involve a signifiesnt increase in the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in the margin of safety.
The proposed change has been reviewed with respect to these three factors and it has been determined that the proposed change does not involve a significant hazard because:
1.
The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
The proposed change involves the removal of license conditions associated with teardowns and certain inspections on the Transamerica Delaval, Inc. (TDI) Emergency Diesel Generators (EDG). A failure of an EDG is not an initiating event for any Updated Safety Analysis Report (USAR) Chapter 15 accident scenario. Accordingly, there could be no increase in the probability of any accident previously evaluated. The availability and reliability of the EDGs will remain within the limits previously assumed in the safety analyses. Eliminating the disassembly and the specified inspections vould actually tend to decrease the consequences of an accident because, as indicated in Topical Report TDI-EDG-001-A, " Basis for Hodification to Inspection Requirements for Transamerica Delaval, Inc., Emergency Diesel Generators," this action vill improve the availability of the engines for service, especially during outages, while maintaining current reliability levels. Therefore, removal of the existing conditions from the operating license vill not result in an increase in the consequences of an accident previously evaluated.
2.
The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
The proposa' i'moval of the license conditions associated with the TDI diesel generators does not affect the design or function of any plant system, structure, or component, nor does it change the way plant systems are operated. No modifications or additions to plant equipment are involved. Therefore, removal of the existing conditions from the operating license vill not create the possibility of a new or different kind of accident from any previously evaluated.

The proposed change does not result in a significant reduction in the margin of safety.
The proposed removal of the EDG license conditions from the Operating License does not affect any parameters which would result in a significant reduction in margin of safety because the results of the operational data and inspections have demonstrated that the additional license conditions are not required to ensure that the EDGs will be maintained with a reliability consistent with that assumed for the safety analyses. Therefore, the proposed changes do not involve a significant reduction in the margin of safety.
