Licensee Action on Previous Inspection Findings Not inspected.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are. acceptable or may involve noncompliance or deviations.
A new unresolved item identified during this inspection is discussed in paragraph 7.c.
Status of IE Bulletins (IEBs) (8nits 1, 2, and 3)
(Closed)
IEB 259, 260, 296/80-BU-21:
Valve Yokes Supplied by Malcolm Foundry Company, Inc.
The licensee's response letter for this bulletin, dated December 5, 1980, has been received and reviewed by NRC Region II.
The letter response indicates that the licensee has determined that they do not have any valve parts cast by Malcolm Foundry in any active valves in the three Browns Ferry units.
The bulletin is considered closed based on this response.
Within the area examined, no violations or deviations were identifie Nondestructive Examination (Units 1, 2 and 3)
The inspector reviewed licensee penetrant examination procedures utilized for maintenance and modification work for compliance with applicable code and regulatory requirements.
The licensee identified three penetrant examination procedures as applicable to their main-tenance and modification work: (1) NPT-NC-1 RI; (2} BF-PT-1 RO, and (3) N-PT-2 RO.
The applicable code identified to the work was USAS B31. 1-1967.
The inspector examined the three procedures for proper approval as well as reviewing procedure BF-PT-1 RO for technical adequacy.
Within the areas examined no violations or deviations were identified.
7.
Welding (Units 1, 2 and 3)
The inspector examined the licensee's controls and procedures for maintenance and modification welding of safety related systems to determine compliance with applicable code and regul'atory require-ments.
The code applicable to this welding is USAS B31. 1-1967.
The areas examined by the inspector are as follows:
a.
Welding Procedures The inspector reviewed the licensee's procedures for gas tungsten arc welding and shielded metal arc welding, as contained in Browns Ferry procedure N73H2 (3/30/81), for compliance with the applicable code.
b.
Welding Material Control The inspector reviewed the licensee's controls on welding materials to determine the adequacy of storage, handling and disbursement.
The licensee's procedural requirements for these controls are contained in the licensee's procedures N73M2, HAI-12 and MAI-21.
Implementation of the procedural requirements was observed at the issue stations.
C.
Welder Performance gualifications fhe inspector reviewed the performance qualification records of three welders to determine compliance with applicable code requirements.
In addition, the inspector verified maintenance of welding qualifications for the three welders through a
review of welding material issue records.
The inspector found that the licensee did not have a procedure which described the method being used to track maintenance of welder qualification and that cognizant licensee personnel did not appear to fully understand how maintenance of qualification was to be assured.
This lack of procedural requirements is identified as unresolved item 50-259, 260, 296/81-11, Lack of Procedure for Maintenance of Welder gualifications.
No instances of failure to comply with code requirements for proper maintenance of welder quali-fications were identified by the inspecto c

Within the areas examined, no violations or deviations were identified.
8.
Inservice Inspection - Observation of Work and Work Activities (Unit 1)
The NRC inspector observed performance of ultrasonic examination activities for inservice inspection (ISI) of reactor vessel nozzle to flange weld N-6A.
The activities were observed for compliance with code and regulatory requirements.
The code applicable to this work is ASME Section XI (71 S 71).
The inspector observed only the longitudinal wave portion of the UT examination.
The examination was observed to verify availability of approved procedure (N-UT-1 R4), personnel knowledgeable in the 'examination method, proper recording of results and conformance with procedure technical requirements (apparatus, coverage, scanning rate, calibration, search unit size and frequency, beam angle, DAC curve, reference level and recording methods).
Within the areas examined, no violations or deviations were identifie * ~.'
