The unresolved item described in paragraph 6 below was discussed in detail.
5.
Independent Inspection Effort The inspector observed a portion of the 60 degree shear wave ultrasonic testing (UT) of Steam Generator No. 2 tube sheet weld no. SGW-A2 to determine if code and procedure requirements were being met.
The applicable code for preservice inspection (PSI) is the ASME Boiler the Pressure Vessel Code Section XI, 1974 edition plus' addenda through the
RII Rpt. No. 50-327/79-01-2-Summer of 1975.
The applicable procedure was LMT-UT-2, Revision 11.
Areas reviewed included:
type of equipment used, including frequency, linearity, extent of coverage (beam / angle) provided, size of transducer; scanning technique; calibration methods; DAC curve; and, method of recording and evaluating indications.
No items of noncompliance or deviations were identified.
6.
Preservice Inspection-Review of Program The applicable code for PSI is identified in paragraph 5.
TVA has contracted with LMT for performance of manual UT inspection for PSI and Southwest Research, Inc. (SwRI) for reactor vessel inspections. The TVA central of fice Power Plant Maintenance Branch of the Division of Power Production is assigned responsibility for preparation and administration of the PSI program and provides personnel to perform the functions of the Authorized Inspector.
Plant QA staff provide surveillance of PSI activities and the independent audit function is provided by the central office QA and Audit Staff of the Office of Power.
The Sequoyah Operations QA Manual contains the TVA QA requirements applicable to PSI.
Records requirements are contained in Sequoyah administrative instruction AI-7, Revision 7.
Other documents containing QA program requirements are as follows: LMT QA Manual; SwRI QA Manual; Office of Power QA Manual audit section and Quality Assurance Plan; Office of Power QAAS Procedures 3.1, Revision 3 (" Quality Program Audits"),
3 2, Revision 2 (" Quality Program Audit Planning") and 4.1, Revision 0 ("QA Training Prcgram"); TVA liquid penetrant test procedure SQ-PT-1, Revision 0; and TVA procedure titled (no number), " Duties of NDE Inspector-Division of Power Production".
The inspector reviewed the above documents to determine if requirements were met for providing controls in the following areas (as applicable):
organization structure and QA personnel including qualifications, respon-sibilities, duties and indoctrination / training of QA personnel; audit procedures / checklists; scope and purpose of audits being performed; audit schedules (the inspector verified that an audit was scheduled of the Sequoyah PSI); qualifications and responsibilities of auditors; establishment of general quality requirements applicable to PSI; proce-dure / program control; identification components and systems covered by PSI; establishment of appropriate PSI procedures; control of corrective actions; control of the QA manual; document control; control of records including examination results, equipment lists and certifications, calibration data, calibration block data, personnel qualifications, drawings and weld lists; and control of records storage.

i RII Rpt. No. 50-327/79-01-3-The Sequoyah Operations QA Manual, Part III, Section 7.2, dated January 21, 1977 requires that, "The identification of significant conditions adverse to quality, the cause of the condition, and the corrective action taken shall be documented".
TVA informed the inspector that conditions such as performance of UT inspection with equipment out of calibration, expiration of personnel qualification, use of inadequate technique, etc., are normally corrected without formal documentation.
It could not be determined during the time of this inspection if any conditions such as those exampled above had been found by TVA at Sequoyah which should have been documented but were not.
Further review is needed to determine if any of these types of con-ditions have been found at Sequoyah and to what extent formal documentation is necessary for the PSI program. This is unresolved item number 327/79-01-01.
No items of noncompliance or deviations were identified.
7.
Preservice Inspection-Review of Procedures The applicable code for PSI is identified in Paragraph 5.
The inspector reviewed the TVA liquid penetrant (PT) test procedure SQ-PT-1, Revision 0 to determine if PT was adequately controlled and code requirements were delineated.
The following areas were considered in the review:
method consistent with ASKE Code; identification of brand names and specific types of materials; control of sulfur and halogens in materials; surface preparation; control of technique such as cleaning, drying, penetrant application, dwell time, surface temperature, penetront removal, application of developer and evaluation; and, qualification of procedure and personnel.
No items of noncompliance or deviations were identified.
8.
Preservice Inspection-Data Review and Evaluation The applicable code for PSI is identified in Paragraph 5.
The inspector reviewed the temporary filing system for manual UT inspection records and reviewed UT records for six pipe welds to determine if requirements were being met. Areas reviewed included examination results, equipment data, calibration data, identification of couplant, chart recordings, evaluation of findings and disposition, extent of inspection, deviations f rom normal procedure, calibration re-verification, accurate recording of indications, record reviews and control of records storage.
