UNIT 2 ICE CONDENSER INSPECTION

SUMMARY

OF SI-106.3 TEST RESULTS Bays 1, 2,17, and 20 met 33 percent inspection-criteria.

Fifty-four flow passages were inspected.

Bays 3, 5. 6, 8, 9,10,13,15,16. - 18.19, 23,- and.24 met the :100 percent inspection criteria. All 162 flow passages were inspected.

Bays 4, 7, 11,-12, 14, 21.-and 22 failed the 100 percent inspection criteria. -These bays were cleaned reinspected, and met.the 100 percent inspection criteria.

Approximately 7 percent (275 out of 3888) of the flow passages were inspected using the camera.

The remaining flow passages were inspected-using the drop light.

Two CAQRs were written during the-performance of the test.

CAQR SQP901502 was written because of miscellaneous debris found during the inspection.

CAQR SQP901503 was written when Bays 4, 7, 11, 12, 14.- 21, and 22 failed to meet'the'15 percent blockage criteria.
