Preoperational (Raseline) Inspection Program Review According to the FSAR, the reactor coolant pressure boundary inservice inspection program is to be in accordance with Section XI of the ASME Boiler and Pressure Vessel Code,1971, including the 1971 winter addenda.

Prior to initial unit operation, B&W is performing the required non-destructive examination (NDE) of reactor coolant system pressure boundary welds to establish preoperational integrity and baseline data for future inspections. B&W reported that the required in-spections are complete except for the coreflood piping, decay heat removal crossover piping modification and the reactor vessel where the remote ultrasonic tool will be used.

B&W has not completed its evaluation of all the indications found; however, one proble.' area on primary piping was identified.

In-dications were noted 'n MK39, a 74* 30' elbow in the outside seam of the lAl discharge line (reactor inlet line). The indications were detected by longitudir il beam normal to the pipe surface, which is the most likely method to find laminar types of indications. Angle beam showed nothing reportable and fabrication radiographs were reviewed as well as new radiographs taken in the suspected area.

After plotting and review of the ultrasonic and radiographic test results, B&W resolved the indications as laminations in the pipe.

The inspector reviewed the NDE procedures to be used for the baseline inspection and no discrepancies were noted. The inspector stated that a review of all the baseline inspection data, including the remote UT tool data used on the reactor vessel, would be required by RO prior to licensing. The licensee agreed to keep RO informed as to when the remaining baseline inspection would be performed so that this could be witnessed by the inspector.

3.

Followup Record Review of Welding and Nondestructive Testing The inspector conducted a walkthrough inspection of completed weld (' 'N joints on the decay heat removal crossover modification located in s

\\ ')

the reactor building as well as the reactor building spray system, t

makeup and purification system, and decay heat system all located in the auxiliary building. Contour and weld profile appeared adequate except for the velds in the reactor building spray system, as noted below, and there were no indications of are strikes or weld splatter.

The inspector reviewed Bechtel's recordt of QC inspection of welding on the above mentioned systems. In order to test Bechtel's quality

,

control records for completeness and accuracy, the inspector selected the following list of field welds during a visual inspection of welded joints:
