SURVEILLANCE OF CONTAINMENT STRUCTURE INTERIOR AND EXTERIOR SURFACES 1.0 PURPOSE

.1 To provide guidelines for an annual visual examination of the containment structure's accessible interior and exterior surfaces.

.2 To provide guidelines for a visual inspection of the containment structure's accessible interior and exterior surfaces prior to any integrated leak test.

.3 To determine at the frequency specified in 1.1 and 1.2 if there is any evidence of deterioration which may affect either the containment structural integrity or leak-tightness.

3.0 LIMITS AND PRECAUTIONS

.1 This inspection should nor= ally be scheduled during an outage or refueling shutdown to minimize the need of sending an inspector into the containment during reactor operation.

.2 The discovery of any significant deterioration shall be accompanied by corrective action in accordance with acceptable procedures. Any 1

corrective action shall be reported as part of the. test results.

4.0 PROCEDURE

.1 Visual Examination of the containment structure's accessible l1 exterior surfaces.
