SUMMARY This routine, unannounced inspection was conducted on site in the areas of Unit 1 inservice inspection (ISI), fabrication NOE acceptance and preservice inspection (PSI) of replacement welds in the Recirculation Spray Syste Also, a review of the repair organizations welder qualification program, relative to the Recirculation Spray System replacement welds, was accomplishe Currently, there is a possible weakness in the licensee's program for assuring the reliability of radiographic film interpretation for item acceptance; Radiographic film interpretation by qualified interpre-ters is not being sampled to assure the continual adequacy of the interpretations~
See paragraph 2.b.(1).
All other areas inspected appeared to be adequately controlle In the areas inspected, violations or deviations were not identifie.

The inspector reviewed UT Procedures NDE-5-UT-l, NDE-UT-204, and ISI-206 to ascertain whether they had been reviewed and approved in accordance with the licensee's established QA procedure The procedures were review for technical adequacy and conformance with the ASME Code Section V Article 5 and other license-commitments/requirements in the following listed areas:
ty$'e--of * apparatus used; extent of coverage of weldment; calibration requirements; search units; beam angles; DAC curves; reference level for monitoring discontinuities; method for demonstrating penetration; limits for evaluating and recording indications; recording significant indications; and, acceptance limit (3)

(73053B)
The inspector observed work activities and reviewed certification records of equipment, materials, and NOE personnel that was extracted from examination data records that were generated during the required ISI/PSI examinations during this outag The observations an reviews conducted by the inspector are documented belo (1)
The inspector observed the below listed radiographs being interpreted for acceptance by the licensee's qualified film interprete These observations were conducted in order to assess the interpreter's ability to apply the applicable acceptance criteria, determine if the film quality is acceptable in accordance with the applicable code requirements, and specifically to verify the interpreter's proficiency for determining the adequacy of the following:
penetrameter type, size, and placement; penetrameter sensitivity; film density and density variation; film identification; weld coverage; and, radiographic techniqu Drawing N Weld N Radiographic View DC-87-22-Ell 7

(2)
radiographic film interpretation following the final item acceptance by a film interprete The inspector was concern that currently, there is no sampling program in place for assuring the reliability of radiographic film interpritation: This is normally accomplished by requiring a second independent radiographic film evaluation by another a qualified film interpreter. The inspector discussed his concern with the site NOE Supervisor, the Corporate Level III Senior Staff Specialist, and the Corporate !SI NOE Services Manage The fol lowing agreements were made as a result of these discussions:
The Corporate Level III will immediately initiate a policy memorandum unofficially requiring a second independent interpretation of radiographic film in specific instance Corporate Management will, within the next 90 days, establish a documented formalized program that contains guidelines indicating when radiographic film will be required to have a second independent interpretatio The inspector informed the licensee that an Inspector Followup Item would be initiated in order to follow the licensee's progress with regard to this concer The below listed radiographic film was independently interpreted by the NRC inspector to determine if radiographic quality was in accordance with the applicable procedure and Code requirements and to specifically verify the following:
penetrameter type, size, and placement; penetrameter sensitivity; film density and density variation; film identification; film quality; weld coverage; and, disposition of the weld Drawing N Weld N Radiographic View DC-87-22-El21

The NRC inspector requested that this area be re-radiographed with the radioactive source in a slightly different position from the original radiograph in order to see if a positive identification of the crack like indication could be determine The area was re-radiographed and the film was interpreted by the licensee Corporate Level III and the NRC inspecto The indication was determined to be a surface indication and was not connected to the por fla The weld in this area was considered acceptable by applicable acceptance standard (3)
The inspector reviewed the calibration documentation for the below listed radiographic film interpretation equipmen Densitometer - Serial No. 6346 NBS Film Strip - CSY-178238 (Item 1)
