SUMMARY: Next visit schedule is 10-11 June 2009.

All improper works on non pressure parts: C-frame & Boiler casing primer paint/Field Weld able primer,

rectification of cutting surface of Stub column for module 1A and visually spatter on C-frame after

painted have to be closed out before final inspection of each component.

The balance Mock up test report of finned tubes is not ready to offer for review during this visit. APESI

to speed up for completion of mock up test report.

APESI need to maintain all plastic caps being installed at all nozzles opening during storage of harps

assembly after hydro test. Two plastic caps were missed from nozzle opening of harps assembly at bay

6.

Actions: APESI has to be improved all works of non pressure parts to meets drawing and specification.
