==1.0  INTRODUCTION==

This topical report has three purposes:
(1)    To present GSU's Program Plan to qualify the Transamerica Delaval, Inc. (TDI) manufactured standby diesel generators for River Bend Station.
(2)   To provide the Staff an opportunity to review, in advance, the plans for testing, post test inspection, and long term surveillance and monitoring.
(3)   To submit for NRC Staff review, the current results of design review and preservice inspection activities at River Bend Station.
       'GSU initiated the Diesel Qualification Program at River Bend Station in Novemb.z, 1983 in response to TDI diesel component failures elsewhere and identified potential deficiencies in TDI's quality assurance program.
The objectives of the River Bend Diesel Qualifications Program are:
(1)   To evaluate the TDI diesels and; (2)  to determine what is necessary to assure reliable standby power at River Bend Station. The Diesel Qualification Program includes activities to solve the known problems of the TDI diesels and; (3)   to obtain NEC approval of the standbv power supplies for River Bend Station.
The GSU approach to qualification of the TDI diesels is:
(1)   To correct the known problems before the diesels are operated at River Bend Station. This involves preservice engine disassembly for inspection, upgrading, and rebuilding.
(2)   To confirm engine reliability by testing and post test inspection, without engine disassembly.
(3)  To assure continued diesel reliability by a prcgram of inservice surveillance, inspection, monitoring, and preventative maintenance.

The feasibility of this approach has been established through the design reviews provided by the TDI Diesel Generator Owners Group, the testing and inspections performed by the TDI diesel owners, and the product improvement recommendations provided by TDI. GSU and its contractors have devoted an intensive effort to accumulate this experience and to implement corrective action to improve diesel generator reliability prior to operation of the engines at River Bend Station. After rebuilding, the engines will be tested to confirm operational reliability. After testing, the engines will be inspected to identify latent defects not disclosed during rebuilding or testing.                3  -
This inspection will involve minor disassembly, sufficient to detect latent problems, but not so extensive as to require retesting.                        y 5
Figure I shows the logical relationship of program tasks, and Figure 2                 y shows the program schedule. The initial phase involves evaluation of                   _
industry experience, design review recommendations, and preservice                    j inspection results. The second phase involves engine rework, rebuilding, confirmatory testing and post test inspection. This phase                  g is expected to result in successful qualification of the TDI diesels.                 ;
3 The last phase is a ' program of continuing surveillance, inspection,                  j monitoring, and preventative maintenance.      The continuing surveillance             j and monitoring program will be finalized after the post test                          -
inspection is completed.                                                              j m
This report describes the plans for design reviews, inspections,                       j testing, and long term preventative maintenance, surveillance and                        ;
monitoring. The format of the report permits the results of ongoing                    =
activities to be added by revisions or supplements as the work                        ;
proceeds. When complete, the report will describe, or incorporate by                   _
reference, the results of the design reviews, preservice inspections,                 -
rework activities, testing, and post test inspections. Data presented                 i is current as of July 5, 1984.                                                        1 s

  ;   2.1 Industry' Experience Review The purpose of this activity is to define the known problems of the
          'TDI engines and to determine if these problems might be applicable to g       -River Bend Station.
Review of industry experience data accumulated by the TDI Diesel Generator Owners Group.
Visits by River Bend Project Personnel to observe diesel inspections at other nuclear stations.
           -1    Participation in TDI Diesel Owners Group meetings and activities.
          ' '    Informal exchange of information with other TDI diesel owners.
The accumulated experience is evaluated for applicability to the River Bend Station diesels. Those items considered applicable are further investigated. This either is done as part of the TDI Diesel Generator Owners Group Review Quality Revalidation effort, or they are added to the work list of inspections, tests, or investigations conducted'by GSU and its contractors at River Bend Station. Results of industry experience reviews conducted to date are reflected in the plans for design-review, preservice inspection, rework, testing, post test inspection, and surveillance and monitoring which are described in later sections of this report.

2.3 Preservice Inspection The purpose of the preservice inspection effort is to verify that the installation is complete and correct and that the manufactured quality of the engines comply with the design requirements. This will be done in three steps:
(1)     As built installation verification. This includes inspections by TDI and major subvendors to TDI, including Electric Products (electric generator), RTE Delta (switchgear), Elliot (turbocharger), and Woodward (governor). In addition, GSU inspects other components selected from industry experience information. The purpose of these inspections is to verify that the engine installation is complete and correct. A list of inspections performed and the results are listed in Tabis 3.
(2)     Preliminary testing of auxiliary components and systems. The purpose of these tests is to verify that auxiliary systems, interlocks, controls, and alarms operate in accordance with specifications. This includes system flushing, hydrostatic testing, relief valve testing for setpoint and seal leakage, initial startup, operation, and performance testing and vibration testing of pumps and compressors, performance testing of air dryers, and individual checkout of all electrical components and instrument loops.
(3)     Preservice disassembly inspection. The purpose of this inspection is to verify that the manufactured quality of the engines is in accordance with the requirements established by the TDI Diesel Generator Owners Group design reviews. This inspection involves removal of cylinder heads, pistons, connecting rods, and cylinder liners for detailed part-by-part inspection. In addition, the turbochargers will be disassembled for inspection. Inspection of the crankshaft, gear case, and camshaft will be performed in situ.
Table 3 lists the engine component groups, the inspection methods employed, and inspection results. Where parts are replaced, the replacements are subjected to the same inspections.

2.4 Rework A number of product improvepents and upgrades are now availabic for TDI engines which improve reliability. GSU has elected to install a number of these improvements as detailed la Table 1. The following paragraphs describe the benefits of the significant upgrades, w
Cylinder block and liners. The cylinder liners, cylinder head,
   ,              studs and block liner landing surfaces will be modified to        -
comply with TDI's current manufacturing specification. The modification reduces cylinder block stress by reducing mechanical interference between the cylinder head, block and liner, and by increasing the vertical distance between the stud threads in the block and the liher landing surface. These menstrements will increase the margin against cylinder block cracking.
Pistons. The original pistons will be replaced by the improved model "AE" piston, the current TDI production standard, inspected to the criteria of the TDI Diesel Generctor Owners Group. Availabic information indicates that the original heat treated and stress relieved AN pistons are acceptable for service. However, the AE pistons were considered desirable because of lower piston skirt stresses and favorable operating experience. As part of the AE piston installation, other TDI product improvements will be installed. These include improved piston rings to reduce the likelyhood of liner scuffing during break-in, rework of piston crowns to reduce liner wear and oil
     -            'Lonsumption, and an improved piston pin retaining ring'to improve maintainability.
Valve pushrods. The improved friction welded pushrods were installed as recommended by the TDI Owners Group Design Review.
Jacket water pump. The jacket water pump will be reworked to include a modular iron impellar without a keyway as recommended by the TDI Diesel Generator Owners Group.
Turbocharger. The turbocharger lubrication system will be modified to improve lubrication during starting and reduce thrust bearing wear. The turbocharger mounting bracket will be stiffened to reduce vibration and a turbocharger speed measuring device will be installed on one engine to obtain test data useful in verifying the adequacy of the prelubrication system.

2.5I Con'firmatory Testing The ' purpose of this activity is to verify engine reliability following engine inspection and rebuilding. Table 5 describes the tests to be performed. The preoperational tests described in Section 14.2.12.1.36 (Revised) will be performed in conjunction with the tests described in this section. The revised FSAR Section 14.2.12.1.36 is reproduced as Appendix 1 of this report.
The proposed testing program does not comply with the requirements of Pegulatory Guide 1.108. The number of start tests is less than specified in Regulatory Guide 1.108, Section C.2.a(9), and the overload test described in Regulator Guide 1.108, Section C.2.a(3), is not planned. With respect to the start tests,.given the documented high starting reliability of the TDI engines, the proposed program of
   .y                ten modified starts and.two fast starts is considered an adequate J:                   demonstration of starting reliability. -Additional fast starts would impose additional wear on the engines, thereby subjecting the engines to service for more severe than the expected plant service conditions.
11us overload test is not considered necessary, because the River Bend Station diesels will   not be operated above the continuous rating of
                    .3,500KW. Therefore,  testing at the overload rating is not considered necessary, and could   reduce long term engine reliability by subjecting engine components to   unnecessary stress cycles more severe than expected to occur in   accident conditions.
In tho' event of component failures during testing, GSU uill investigate the root cause, and take corrective action to remedy the problem and prevent reoccurrence. Retesting would be performed if the corrective action is considered to affect the test objectives i.e.:
                    .1) the ability to deliver rated output, 2) the ability to start reliably,'or 5) the torsional vibrator characteristic of the crankshaft.

2.6 Post Test Inspection Following the. tests described in Section 2.5, GSU will perform an engine inspection consisting' of the items in Table 6. The purpose of this inspection is to look for potential latent problems not discovered in earlier-inspections and tests and verify readiness for x                          -further operation. The preoperational test phase, consisting of the 1                                                tests defined in FSAR Section 14.2.12.1.36, (see Appendix 1), will begin'upon satisfactory completion of the inspection and any required

Critical components 1'                      can be adequately inspected by removing access covers and by oil analysis. The oil . analysis will indicate abnormal wear of bushings
                                                     .and bearings and the elementa1Lanalysis will identify the component in distress. The oil analysis will also serve as a baseline for continued surveillance _in the operating phase.
