Licensee Action on Previous Inspection Findings (Closed) Violation 389/81-07-07, Failure to follow ultrasonic procedure for_ PSI.. Florida Power and Light Company's (FP&L) letter of response dated July 8,1981, has been reviewed and determined to be acceptable by Region II.
Based on examination of corrective actions as stated in the letter of response, the inspectors concluded that FP&L had determined the full extent of the subject violation, performed the necessary survey and followup actions to correct the present conditions and developed the neces-sary corrective actions to preclude recurrence of similar circumstances.
The corrective actions identified in the letter of response have been implemented.

The weld traveler for weld joint CS-0041-FW-001 indicated that the above joint was a_ pipe spool to an elbow-weld, when in fact the above weld joins a pipe spool to a pipe.
The licensee stated that the records are being reviewed as part of the program to document Code Data Reports. This review would identify and correct the type of records errors identified by the inspector. The errors identified will be. corrected. A review of the above records and the Code Data Report documentation review process will be identified as inspector followup item = 389/82-07-03, Review of Code Data Report review process.

Preservice Inspection - Review e f Program The inspectors reviewed the licensee's preservice inspection (PSI) program as described below to determine whether regulatory requirements were being met. The PSI is being performeo in accordance with the ASME Boiler and Pressure Vessel Code,Section XI, 1977 edition with addenda through S78 as modified by 10 CFR 50.55a.(g).
As noted in RII report 50-389/81-07, Combustion Engineering (CE) had been contracted for the PSI. However, after inspection of the reactor coolant loops, FP&L decided to issue their own insoection program and perform the inspection themselves. Therefore, the inspection is being performed using FP&L program and procedures with Nuclear Energy Services (NES) furnishing the examination personnel.
The program description, inspection plan description and the inspection plan are still in the process of being changed from CE documents to FP&L. The inspection plan is being formally approved and issued by individual " zones" rather than issue of the entire inspection plan.
a.
The inspectors reviewed the following documents:
(1) FP&L QI 10 PR/PSL-2, Revision 1, "Preservice Inspection (PSI)"
(2) FP&L PSI Implementing Instructions -
- 1
" Preparation and Approval of PSI Implementing Instructions"

FP&L "Preservice Inspection Plan Description", Rough Draft.
The documents were reviewed in the areas of:
Program Approval Organizational Structure General QA requirements including documentation, deviations from PSI program and identification of components to be inspected.
Work and quality inspection procedures.
b.
During review of the above documents, the inspector noted that the qualification requirements for the PSI Site Supervisor are not defined in the program and procedures at the site. Discussions with licensee personnel revealed that qualification requirements exist for the site supervisor position, but not necessarily in a PSI procedure.
The licensee agreed to review the documents covering the site supervisor position and determine the need for any clarification to PSI proce-dures.
This matter will be identified as inspector followup item 389/92-07-01, Clarification of Qualification Requirements for PSI Site Supervisor.
Within the areas inspected, no violations or deviations were identified.
9.
Preservice Inspection - Review of Procedures The inspectors reviewed the PSI procedures as described below to determine whether the procedures were consistent with regulatory requirements. See paragraph 8. above for the applicable Code.
a.
The following procedures were reviewed in the areas of procedure approval, qualification of NDE personnel and compilation of records:
.
.
.
.
(1) NDE 5.1, Revision OB, FCN00028, " Ultrasonic Examination of Pres-sure Vessel Welds 22-1/2 inches in thickness".
(2) NDE 3.1, Revision IA, FCN0005, " Liquid Penetrant Examination Visible Dye Technique".
3) NDE 2.1, Revision 0A, FCN00012, " Magnetic Particle Examination".
(4) %DE 5.2, Revision 0A, FCN00017, " Ultrasonic Examination Procedure For Ferritic Piping Welds" (5) NDE 5.4, Revision 0,
" Ultrasonic Examination Procedure for Austenitic Piping Welds" b.
In addition to the review above, procedure NDE 5.1 was reviewed for technical content relative to:
(1) Type of apparatus (2) Extent of coverage including beam angles and scanning technique (3) Calibration requirements (4) Search units (5) DAC curves (6) Reference level for monitoring discontinuities (7) Method of demonstrating penetration (8)
Levels for evaluating and recording indications (9) Acceptance standards Within the areas inspected, no violations or deviations were identified.
10.
Preservice Inspection - Observation of Work and Work Activities The inspectors observed the PSI activities described below to determine
whether these activities were being performed in accordance with regulatory I
requirements and licensee procedures.
See paragraph 8.
above for the applicable code.
a.
Personnel qualification records for four Level II and four Level I NDE examiners were reviewed.
b.
In process ultrasonic (UT) inspection including calibration on appli-cable calibration blocks, was observed to the extent indicated for the following welds:

Loop A2 Reactor 103-722-A 45 Angle Beam Coolant Cold Leg Zone 8 The inspections were compared with applicable procedures in the following areas:
(1) Availability of and compliance with approved NDE procedures (2) Use of knowledgeable NDE personnel (3) Use of NDE personnel qualified to the proper level (4) Recording of inspection results (5) Type of apparatus used (6) Extent of coverage of weldment (7) Calibration requirments (8) Search Units (9) Beam Angles (10) DAC Curves (11) Reference level for monitoring discontinuities (12) Method for demonstration penetration (13)
Limits for evaluating and recording indications (14) Recc-ding significant indications (15) Acceptance limits During observation of UT inspection of steam generator 2A weld 106-201 on February 18, 1982, the inspectors noted that the UT instrument sweep distance was set up such that the full CRT screen width represented approximately the full thickness of the material being inspected.
Paragraph 5.2.1 of the applicable procedure, NDE 5.1, requires that the sweep distance be set up such that at least 1/4t beyond the nominal production material thickness be included on the CRT screen.
This failure to follow NDE procedure is an example of violation 389/82-07-02 discussed further in paragraph 10.e.
c.
In addition to observation of calibration for the RV closure head welds above, the inspector observed photographing of the initial pulse shape as required by Regulatory Guide 1.150, paragraph C.1.5.
The loaded and unloaded pulse shapes were photographed.

d.
The inspectors observed the automatic equipment used for UT inspec-tion of reactor vessel welds.
At the time of the observation, no inspections were in process.
Preparations were being made to cali-brate, and perform additional scans on weld 201-141 in accordance with SwRI procedure 700-6, Revision 10.
The inspector discussed
,
set up and operation of the equipment with examination personnel.
- x e.
On February 17, 1982, the inspectors observed liquid penetrant (PT)
inspection of weld 05 on line RC-0116 (2" diameter stainless steel socket weld). The inspector noted that the examiner did not apply penetrant to the base material on the valve side of the weld.
Fara-

graph 5.3.1 of OI 9.5, the applicable procedure, requires that at least the adjacent 1/2-inch area on each side of the weld be thoroughly and uniformly coated with penetrant.
A+. the time the PT inspection was observed it was assumed to be a construction inspection.
However, later investigation revealed that construction surface examination results for Class 1 welds are used to satisfy PSI inspection require-ments if certain conditions are met.
The determination to use con-struction PT inspections to satisfy PSI requirements was based on a review of the construction PT procedure (QI 9.5) to determine that the procedure met ASME Section XI, which requires PT inspection of 1/2-inch base material on each side of the weld.
The above failure to follow procedure and that discussed in paragraph 10.b. are in violation of 10 CFR 50, Appendix B, Criterion V.
This violation is identified as 389/82-07-02, " Failure to Follow NDE Proce-dures".

Within the areas inspected, no violations or deviations were identified except as noted in paragraphs 10.b and 10.e.
