Subject:  Clarification of 11/9/94 Master Connecting Rod 
          10 CFR Part 21 Report Revision

Dear Sir:

The recent revision to the above report (reference QCG-9995) identifies
suspect master connecting rods and contains information concerning the
location in the engine (crankshaft throw) for these rods.

The purpose of this letter is to inform the affected utilities that the
location/throw may not be as stated on the subject report, and that the
suspect rods may be in different throw locations.  This has been verbally
discussed with affected utilities as they have conducted their
inspections.

Horne, Manager, Nuclear and Analytical Engineering at 412-458-3543 or
John R. Schneider, Manager, Quality Assurance at 412-458-3434.
