Prairie Island - Review of 2008 Unit 2 180-Day SG Tube Inspection Report

Dale, The NRC staff is reviewing the subject report, which was submitted on April 27, 2009 (ADAMS Accession No. ML091180466), and would like confirmation of several items, as follows:
1. Confirm that no crack-like indications were left in service except for those that would have been permitted to be left in service with the F* repair criteria.
2. Confirm that the only crack-like indications detected were either located in the tubesheet crevice or the sludge pile at the top of the tubesheet.
3. Confirm that no degradation was observed during the inspections of the upper internals of the steam generators.
4. Confirm that no wear was attributed to loose parts. In addition, confirm that if any loose parts were left in the steam generators, an evaluation was performed and that it confirmed the acceptability of leaving the parts in service.

Please review and let me know if you'd like to have a telecon to clarify this request. An email response to these questions would be satisfactory.
