d.
(Closed) Deficiency 370/79-08-02, Failure to Record Weld Fabrication Changes. Duke letter of response dated May 3, 1979 has been reviewed and determined to be acceptable by Region II.
The inspector held discussions with the project senior QA engineer and examined the corrective actions as stated in the letters of response listed in a, b, c and d above. The inspector concluded that Duke had determined the full extent of the subject noncompliances, performed the necessary survey and followup actions to correct the present conditions and developed the necessary corrective actions to preclude recurrence of similar circiunstances. The corrective actions identified in the letter of response have been implemented.
e.
(Closed) Unresolved 370/79-08-01, Pecord of Weld Machine Output Checks. Administrative memorandum 141 Revision 0 dated April 8, 1979 requires welding machines to be checked for voltage and ampere output on a monthly basis.
Procedure M-4 has been revised to provide for documentation of this activity on form (M-40). The inspector reviewed the records for checks made during June and July, 1979.

Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort a.
Plant Tour (Unit 2)
The inspector performed a general inspection of various work areas to observe certain pipe handling, installation and welding activities in progress and to inspect the general state of housekeeping, cleanliness, including control of unused weld electrodes near the working areas and proper use of wire brushes on stainless steel material.
b.
Observation of Weld Activities (Unit 2)
Welds in various stages of fabrication were selected for observation and record review. The applicable codes were USAS B31.1 or ASME Section III, 1971 Edition.

Hanger Inspection (Unit 1)
At the time of this inspection, the licensee had inspected /
accepted 1000 out of approximately 14697 hangers. The licensee outlined the inspection program which is designed to provide administrative control and technical / engineering support to this effort. Hangers are checked by engineering for conformance with specification and isometric drawing requirements. Field inspections are performed by QC in accordance with construction department procedure M-15E R/4.

-6-A sample of NDE procedures used for the PSI examination of welds were selected for review of content and technical adequacy; these were as follows:
ISI-120, R/7
"UT Examination of Class 1 and 2 Piping Welds Joining Similar and Dissimilar Materials" ISI-240, R/7
" Penetrant Examination of Weld and Base Materials Including Studs, Nuts and Washers" ISI-270 R/4
" Wet or Dry Methods of Magnetic Particle Examination of Welds, Studs, Nuts Bolts" c.
Observation of Work Activities At the time of this inspection, B&W had completed the examina-tion of 29 Class I welds, 395 Class 2 welds, the reactor coolant pumps and Eddy current examination of steam generator tubes; examination of the vessel was performed and completed during September of 1978-this activity was not inspected.
Applicable code requirements are discussed in paragraph 6.a above.
At the time of this inspection, Class 2 pipe welds were being examined. The inspector witnessed the UT examination of the following welds:

ND2F-24-1
.91" x 8" 9 C.2.1.345 360 Intermitant Indications The above welds were examined in accordance with B&W procedure No. ISI-120, Revision 7.
Personnel perfort.ng the examination and interpreting results were thoroughly familiar with the above procedure and properly qualified as verified by their certifications.
Examination results were recorded as required by the PSI program. The apparatus, calibration including DAC curve construction, calibration standard, weld examination (scann.ing)
with 0 degrees and 45 degrees transducers was in compliance with code and procedural requirements.
