Inservice Inspection - Review of Program (Unit 3)
Tennessee Valley Authority (TVA) has contracted with Lambert, MacGill and Thomas,.Inc.
(LMT) to perform and document the inservice inspections (ISI).
ISI is being performed in accordance with the ASME Boiler and Pressure Vessel Code Section XI, 1974 edition plus addenda through Summer 1975.
TVA has developed the ISI program, QA requirements and procedures to control and document inspections.
These documents include the Operations QA Manual; TVA Browns Ferry Nuclear Plant Surveillance Instruction 4.6.6,
"Preservice Baseline Inspection and Inservice Inspection Program, Unit 3";
Procedure N-AI-l, Rev.
1, "Duties of the Authorized TVA Inspector, TVA Nuclear Plants"; procedure N-UT-l, Rev.
1, "Ultrasonic Examination of Nuclear Coolant System Piping";
procedure N-MT-1, Rev.
0, "Dry Magnetic Particle Examination - Prod and Yoke Methods"; procedure BF-PT<<l, Rev.
0,
"Nuclear Penetrant Testing";
and audit checklist for audit no.
OPQAA-BF-79-SP-04.
The inspector reviewed these documents to determine whether appropriate procedures/instructions were provided and requirements were being met in the following areas:
licensee approvals; QA organization; general QA requirements such as specification of quality requirements, control of program deviations, quality documentation and identification of components/systems covered by the program; establishment and control of work procedures to insure control of inspections; control of corrective action; document control; contxol of examination equipment; quality
- records; qualification of personnel; scope of the inspection such as areas to be examined, examination category, method and extent of examination and exemptions; and inspection intervals.

Inservice Inspection - Review of Procedures (Unit 3)
The applicable Code is identified in paragraph 8.
The 'inspector reviewed ISI inspection procedures in detail for conformance to NRC and Code require-ments.
The procedures reveiwed were N-UT-1, Rev.
1', "Ultrasonic Examination of Nuclear Coolant System Piping"; BF-PT-l, Rev.
0, "Nuclear Penetrant Testing"; and N-MT-1, Rev.
0, "Dry Magnetic Particle Examination - Prod and Yoke Methods".
The procedures were reviewed in the areas of procedure approvals; personnel qualification requirements; procedure scope; require-ments for records such as results, data sheets, equipment data, calibration data sheets, calibration blocks, penetrant material, and couplant material; and technical requirements for ultrasonic testing (UT) (type of apparatus, equipment calibration, extent of coverage, test calibration, size and frequency of search units, beam angles, DAC curves, reference level, scanning level, method of demonstrating penetration and recording and evaluation of indications), liquid penetrant test (PT) (type of material analysis of materials, surface preparation, temperature requirements, methods of application and removal of materials, time intervals evaluation of indications and procedure qualification requirements)
and magnetic particle test (MT) (requirement for continuous current, dry particle requirements, irispection technique, prod spacing, amperage for the prod method, yoke pole spacing, yoke lifting power requirements and evaluation of indications).
No items of noncompliance or deviations were identified.
10.
Inservice Inspection - Observation of Work and Work Activities (Unit 3)
Th'e applicable Code is identified in paragraph 8.
The inspector observed inspection activities to determine if NRC and procedural requirements were being met.
The inspector observed portions of L-wave and 45 degree shear wave UT of Main Steam System Weld No. GMS-3-17, portions of MT of reactor vessel stud no'.
25 and PT inspection of Reactor Water Cleanup System support Weld No. RWC-3-Hl.
