License Action on Previous Inspection Findings (Closed) UNR (317/80-21-03): Adequacy of the magnetic particle examina-tion of reactor pressure vessel closure nuts.
This item remained open (Inspection Report 317/83-14) pending the availability of a specific procedure for the magnetic particle examination of the closure nuts.
The inspector reviewed Procedure No. NDE 5.107, Revision 0, Magnetic Particle Examination of Closure Nuts, which was prepared by the licensee's Level III.
The procedure provides for the examination of the closure nuts, including the inside (threaded) surface of the nuts. The technique is a combination of the dry visible particle method and the wet, fluores-cent method with the magnetic field established by means of a magnetic yoke and a coil for the inside surface. Dry, visible particles or wet fluorescent particles may be used on the outside surface and wet fluores-
' cent particles must be used on the inside surface. The inspector found that the procedure adequately defined the method of examination and the acceptance criteria.
Based on the above, this item is considered closed.
(0 pen) NC4 (317/84-06-01): Ultrasonic examination of electrical penetra-tion welds did not comply with ASME Section III requirements. The ultra-sonic examination procedure proposed by the licensee to govern the re-examination of the electrical penetration welds, SwRI-NDT-800-90, Revision 1, did not agree with ASME Section III requirements with regard to the calibration method and recording criteria. Also, calibration block number CC-61 did not contain the required 3/32" diameter side drilled hole at the T location.
The licensee stated at the exit meeting that block CC-61 will be modified to meet the code requirement, and that procedure SwRI-
.
.
NDT-800-90 will be changed to include the Section III applicable require-ments. This item remains open pending completion of the electrical pene-tration ultrasonic examinations in accordance with ASME Section III, Sub-section NE, Class MC Components, 1977 Edition and Winter 1977 Addenda.
3.
Review of Nondestructive Examination (NDE) Implementing Procedures The inspector reviewed the following procedures to ascertain compliance with applicable ASME Code and regulatory requirements:
SwRI-NDT-300-1, Revision 26, " Dry Powder Magnetic Particle
Examination" SwRI-NDT-600-3, Revision 62, Deviation 1, " Manual Ultrasonic
=
Examination of Pressure Piping Welds" BG&E Procedure NDE 5.506, "The Multi-Frequency Eddy Current Exami-
.
nation of Steam Generator Tubes" The above listed procedures were found to meet the applicable code and regulatory requirements.
No violations were identified.
4.
Observations of Work in Progress The inspector observed the ultrasonic examination of pressurizer spray line weld number 3PS-1001 M-22, a 3" diameter pipe to elbow weld. The observation was made to ascertain that procedural requirements were met.
The inspector found that the examination was done in accordance with pro-cedure SwRI-NDT-600-3, revision 62.
The examination equipment was found to be within the calibration period and the examination was performed by properly qualified personnel.
In addition to the above the inspector witnessed the eddy current exami-nation of the following tubes in steam generators number 11 and 12:

142 The examinations were performed by Zetec, Inc. persnnnel using BG&E pro-cedure NDE 5.506. Data were collected as the 0.560 probe was withdrawn from each tube.
The data were recorded on magnetic tape and on a six channel strip chart for evaluation.
The inspector visited the off site location where data were being inter-preted and evaluated by a data analyst provided by Zetec, Inc., the 11-censee's contractor.
Data associated with the following tubes in steam generator number 11 were evaluated in the inspector's presence:

119 At the exit meeting the inspector was informed that 7 tubes in S.G.#11 would be plugged and 5 tubes in S.G. #12 were scheduled for plugging.
Approximately 5100 tubes in S.G#11 and 5450 tubes in S.G#12 were examined at the time.
The eddy current examinations were still in progress when the inspector left the site at the completion of this inspection.
No violations were identifie.

Review of Inservice Inspection (ISI) Data Data associated with the following welds were reviewed to ascertain com-pleteness and compliance with applicable code and regulatory requirements:
Ultrasonic Examination Safety Injection System 24" diameter elbow to pipe weld 24-SI-1201-4.
- Steam Generator #12 deflector assembly to upper head dome weld
SG-12-1.
Magnetic Particle Examination Main Steam System 6" diameter pipe lug weld 6-MS-1207-7PL-5 and
-7 P L-6.
The data sheets identified the ultrasonic couplant to be glycerine. The inspector found two different batches of glycerine available for use on-site. A material certifiestion record was available for one of the batches and, while the inspector was onsite a record of the second batch was obtained from SwRI in San Antonio, Texas.
The ultrasonic data sheets did not identify which batch of glycerine was used for a specific exami-nation, therefore, the couplant was not traceable to a certification record to confirm that the halogen and sulphur content was within permis-sible levels. This is considered unresolved pending licensee action and subsequent NRC review (317/85-11-01).
6.
Nondestructive Examination (NDE) Personnel Qualification / Certification Records Records of SwRI personnel who participated in examinations represented by the data listed in paragraph 5, and in the examination observed by the inspector were reviewed to ascertain that each individual was properly qualified to perform the examinations in which he participated.
The records were found to be complete with the exception of those repre-senting several UT Level II individuals. The records were incomplete in that the documented training and experience did not meet the requirements for total hours necessary to become a level II. At the inspector's re-quest additional information was obtained by the licensee which indicated that the individuals did meet the requirements regarding training and experience. The inspector had no further questions regarding this matter.
No violations were identifie *

Quality Assurance (QA)
The inspector reviewed QA records and interviewed QA personnel to ascertain that ISI activities are audited and that Southwest Research Institute was found by the licensee to be qualified to perform ISI at the site.
The following was included in the inspector's review:
.
QA File: QAG 60-SwRI 84-Program 01, Quality Assurance Audit of South-
=
west Research Institute dated November 16, 1984.
Check List used by licensee QA auditors when performing onsite audits
of ISI activities.
The inspector's discussions with QA personnel indicated that various aspects of the ISI Program were included in audit activities and that licensee QA coverage is a continuing activity during the course of the current refueling outage.
Based on the above, the inspector concluded that licensee onsite QA activi-ties are adequate to assess adherence to the ISI Program.
The audit re-port dated November 16, 1984 verified that, based on the audit at San Antonio, Texas on October 16, 1984, Southwest Research Institute was re-approved to supply inservice inspection services to the licensee.
No violations were identified.
8.
Unresolved Items Unresolved items are items about which more information is required to ascertain whether they are acceptable, violations or deviations. An un-resolved item.is discussed in paragraph 5.
9.
Exit Interview The inspector met with licensee representatives (denoted in paragraph 1)
at the conclusion of the inspection on May 3, 1985. The inspector sum-marized the purpose and scope of the inspection and the findings. At no time during this inspection was written material provided by the inspector to the licensee.
