o ATTACEMENT. 'l
. August 8,1984 '
Responses-to NRC Questions and Recosmendations at the July 26, 1984 meeting at Catawba Nuclear Station Concerning Diesel Engines.
t 1.
Revision to August 1, 1984 response:
In-the August 1,
1984 response, item 2 described the specific lubricating oil grade to be used.
This should be changed to read Exxon Tro4 tar SD-40 rather than the Mobil Product.-
Both products meet TDI's new recommendations.
2.
Identification of Cylinder Heads on lA and IB Engines:
1gg3: -NRC requested that the cylinder heads used on Catawba 1A and IB diesels be identified by groups as deecribed on page 1-2 of the May 1984 report' prepared by-- FaAA entitled ? Evaluation. of Cylinder Heads of Transamerica Delaval Inc. ' Series R-4 Diesel Engines". -
Discussion:
As described in the FaAA report, Group I and II cylinder heads are subject to leakage problens due to manufacturing defects. The FaAA report further describes a program of inspections and periodic engine ' roll and cylinder venting to ensure that head ' defects are detected and internal leakage will not adversely' affect diesel 4
availability.
Response: contains the information, requested in the July 26,- 1984 meeting.
The information listed for the IB engine is as of July "31,.1984.
The IB engine is currently disassembled and the heads are being' inspected.
+
Most of Catawba 1A and IB engine cylinder heads are in Group II with a
small percentage in Group I and III.
In any case, all heads have or will be thoroughly examined to verify that defects are not present.
In.
addition, engine roll and cylinder venting procedures will be performed periodically as described in our letter dated July 16, 1984 on this subject.
