. Post 100 Hour Inspections and l Test of TDI Diesel Generators

Dear Mr. Youngblood:

This letter is intended to clarify our position with respect to the testing and i inspection to be performed following our 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> (approximate) preoperational

testing of the TDI diesel generators. Your le,tter, dated July 22, 1985, identified several tests / inspections to be. performed. These were identified in our February 8, 1985 letter and through subsequ'ent communications with our i staff. You also offered several comments to be factored into our inspection j program.

) We intend to follow the test and inspection program identified in your letter I as well as incorporate your comments with two clarifications / exceptions:

j.I

'l 1. Comment #1 suggests inspecting the turbocharger with the highest re-

! corded exhaust temperature "during the 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> run." We will inspect the turbocharger with the highest recorded exhaust temperature during

,l the longest continuous full load run (24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). Several runs (of 24 il hours or less eac') n comprise the "100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> preoperational testing program."

2. Comment #6 suggests visually inspecting the block tops for cracks where cylinder heads are removed. CEI will be performing inspections of the I cylinder heads, intake and exhaust valves, and cylinder blocks in i accordance with the final Perry DR/QR Program Report. The inspections l5 requested by the TDI Owners Group do not require removal of the cylinder i; heads at the " post 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> /preoperational testing inspection", unless a lr problem is discovered while performing other inspections and further j analysis is required. For example, the DR/QR specifies that the intake o -

and exhaust valves shall be verified to have proper valve seating by l

removing the subcover bonnet and checking for soot. Soot buildup would indicate exhaust blowby and therefore require cylinder head removal for

further inspection. In this situation, with the heads removed, the

cylinder block would also be inspected for cracking.

The final Perry DR/QR Report submitted on March 18, 1985, was based upon the 1atest Owner's Group recommendations and this accounts for the changes between

~

our February 8, 1984 letter and later communications. The final Perry DR/QR Report also includes many recommendations for modification of existing equip-ment. CEI is presently reviewing each modification recommendation and will I install those which will enhance the quality and/or reliability of the Perry engines. All recommendations not adopted following this first review will undergo additional analysis prior to installation or final rejection. CEI will notify NRC for concurrence prior to eliminating or altering any TDI Owners

Group recommendation. All modifications will be completed or reconciled prior

' to startup from the first refueling outage.

Our intent is to continue evaluating any further Owner's Group recommendations as they are developed. We will inform you if 'any such recommendations modify

, our plans regarding the post 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> inspection program.

2 Please feel free to contact me if you have any concerns regarding this matter.
