I.
Potential Problem l
Entry by Bechtel into Steam Generator #2 for special instrumentation installation disclosed Combustion 1
Engineering, Chattanooga, delivered the item with missed factory operations.
1.
Marmon couplings. holding steam separators were not tightened.
2.
Approximately 50% of nuts 'in steam dryers above can deck were not tightened.
3.
One area of incomplete drilling through facing plate resulted in only three (3) of four (4) ' bolt locations being' installed.
I 4.
Sixty (60) PC #273-3503 are not tack welded l
per View T-T of Drawing E-78272-371-020,.
Revision 1.
Also, the dryer deck area-is not clean; it appears debris was generated during fit-up and welding 'of steam. outlet piping.,
These problems would have~ gone undetected had it not been for entry to incorporate instrumentation modification.
II.
Approach To and Status Of Proposed Resolutions Bechtel has requested assistance from Combustion Engineering in evaluating and dispositioning these problems.
III.
Projected Completion of Corrective Action and Submittal of the Final Report The evaluation and final report are forecast to be completed by March 4, 1982.
