Licensee Action on Previous Inspection Findings (Closed) Violation (412/85-14-01).
Failure to provide clear access to welds for ISI. The inspector found that " Field Construction Procedure For Component Support Control", FCP-207, was revised to address the access required for ISI. Additionally, Nonconformance & Disposition Report (N&D)
No. 85-06 and N&D No. 85-08 was issued regarding the two welds which were listed in the original finding. The actions taken by the licensee will serve to minimize recurrence of the problem and based on the inspector's review of those actions, this item is considered closed.
(0 pen) Unresolved Item (412/85-15-01); Potential PSI problems due to weld overlay of piping and lack of vendor As-Built Drawings and RT maps.
The inspector found that the ultrasonic technique which is being used for the
.
examination of the piping welds containing weld overlay was qualified at the EPRI NDE Center at Charlotte, North Carolina using samples containing cracks. Additionally, the technique was used at the Perry Nuclear Power Plant for the examination of overlayed welds. Based on the above, the
_
rv i
.
.
ultrasonic technique was deemed acceptable. The portions of the original item regarding As-Built Drawings and RT maps were not inspected at this time and remain open.
3.
Preservice Inspection (PSI) Program Review The inspector reviewed the licensee's PSI Program to ascertain compliance with ASME Code and regulatory requirements. The following were included in the inspector's review:
- Procedure No. 2.13, Revision 2, "ASME Section XI Integrated Preservice Inspection Program"
- Procedure No. 2.13.5, Revision 2, "ASME Section XI Preservice Inspection Plan For Class 2 Pressure Retaining Components"
- Procedure No. 2.13.6, Revision 1, "ASME Section XI Preservice Inspection Visual Examination Criteria For Pressure Retaining and Component Supports"
- Procedure No. 2.13.7 Revision 1, "ASME Section XI Preservice Inspection Plan For Class 1 Pressure Retaining Components
- Specification No. 10080-DMS-0002, Revision 2, " Specification For Pre-service Steam Generator Eddy Current Inspection Beaver Valley Power Station Unit No. 2" The inspector found that the program contains provisions to assure that the required examinations will be performed and that the resulting data are controlled by the licensee.
No violations were identified.
4.
Procedure Review The inspector reviewed PSI procedures to ascertain compliance with ASME Code,Section XI requirements. The following were included in the in-spector's review:
- GP-102, Revision 1, General Inspection Requirements
- UT-300, Revision 1, General Requirements for Ultrasonic Examinations
- UT-303, Revision 3, Ultrasonic Examination of Austenitic Systems
- LP-101, Revision 1, Solvent Removable Visible Dye The inspector found that the reviewed procedures were technically accept-able for their intended use.
No violations were identifie f
.
.
5.
Observations of. Work in Progress The inspectors observed ultrasonic examinations in progress to ascertain compliance with applicable examination procedures and with regulatory requirements. Portions of the examination of the following welds were included in the inspectors' observations:
Weld 2 - RCS -8-F1, Loop "C" Crossover Leg
Weld 2 - RCS -8-F2, Loop "C" Crossover Leg
Weld 2 - RCS -004-F1, Loop "B" Hotleg a
Weld 2 - SIS -067-F510, Safety Injection System pipe to valve weld a
containing weld overlay.
The above listed welds were examined using refracted longitudinal angle beam focused transducers. The ultrasonic equipment was calibrated using the appropriate calibration standard. The scanning sensitivity was 10 dB greater than the reference level, and indications were recorded at the reference level.
The inspectors found that the examinations were done by qualified technicians in accordance with approved procedures.
No violations were identified.
6.
Review of Personnel Records The personnel records of (4) four NDE Technicians were reviewed to ascer-tain qualification and certification in accordance to ASME and ASNT-TC-1A requirements.
No violations were identified.
7.
Equipment Certification Records The inspector reviewed records of the following ultrasonic transducers to ascertain that Code and regulatory requirements were met:
Serial Number I-22765, O' single element
Serial Number J-22462, Focused, dual element
Serial Number J-22463, Focused, dual element
Serial Number F-16030, Focused, dual element
Serial Number F-20320, Focused, dual element

The inspector found that the records were incompleta in that information was.not available regarding the focal length of the focused transducers used for the examination of cast stainless steel welds and overlayed welds. This is considered unresolved pending the licensee making avail-able the necessary documentation (412/86-05-01).
8.
Unresolved Items Unresolved items are matters about which more information is required to ascertain whether they are acceptable, violations or deviations. An unresolved item is discussed in paragraph 7 of this report.
