/,.10Ci RSO, Part 21 Report J. W. Tangye Gentlenen:
A deviation between actual physical configuration of a two high heat exchanger stack' on the diesel generator skid and the configuration analyzed in' the seismic report ha*. been detected on one of the subject units.
The deviation is the result of worpage at the bolted interface between the diesel generator skid and the heat exchanger mounting feet and between the two heat exchangers ruounting feet.
lione of these units are in an operating nuclear planL.
s t
Discussions are underway with the owner to reach agreement on a :rethod of repai r'.
Our suggested r epair is to reanalyze the arrangement seismically based on a welded joint ra ther than a bolted joint and ef fect the appropriate weld repair before the unit s are placed in service.
We will keep you advised as to the final dispusition of the Limerick units.
This specific mechanical arrangement is unique to the Limerick units.
An investigation of engineering docuraents will be undertak en to determine if the potential' for a similar situation exists on other liodel 38108-1/8 units.
We will advise ynu of the result' of that is:vestigation when complete.
'A copy of this' report is being forwarded to Philadelphia Electric Co.
