2. Inservice Inspection (ISI) Activities

a. ISI Program

This is the second inspection of the final third of the firstinspection interval (10-year) of the ISI Program.

3

The inspector held discussions with licensee personnel andaudit =c' documentation associated with the ISI Program, whichincluded:

-- Oyster Creek Technical Specification 4.3, Reactor CoolantSystem Surveillance

-- Specification QA-1000, dated September 21, 1977, titled," Nondestructive Examination Services"

-- Specification No. 60-74-3, Revision 1, titled, " InserviceInspection for 1977-1979 Outage" including attachment1.16, Revision 1, dated August 23, 1978

,

Procedure 2008, " Inservice Inspection Quality Assurance--

-- Universal Testing Laboratories (UTL's) NondestructiveExamination (NDE) Training and Qualification Manual,dated July 20, 1976

The above listed documentation contain provisions and require-ments for the administration and execution of the examinationsscheduled to be performed during the current refueling outage.

No items of noncompliance with regulatory requirements wereidentified.

b. NDE Imolementing Procedures

The inspector reviewed the following procedures:

UTL-J"".-UT-02, dated September 29, 1978, titled, " Procedure--

for uitrasonic Examination of Reactor Pressure Vessel Fer-ritic Welds in Excess of One Inch Thickness"

-- UTL-JCPL-UT-01, dated June 13, 1978, titled, " UltrasonicWeld Inspection"

UTL-JCPL-PT-02, dated June 7,1978, titled, " Liquid Pene---

trant: Visible Dye, Solvent Removal Method"

The inspector reviewed the above listed procedures for technicaladequacy. This included, but was not limited to the parametersdescribed below for liquid penetrant and ultrasonic examinationtechniques.

,

4

a. Liquid penetrant Techniques

1) The examination method is consistent with the ASMECode requirements.

2) Surface preparation requirements are specified.

3) The method of penetrant application and dwell timesare specified.

4) Component temperature is stipulated.

5) Evaluation and acceptance criteria are pecified andare consistent with applicable ASME Code requirements

b. Ultrasonic Examination Technique

1) The type of apparatus, including frequency range, isspecified.

2) Examination coverage, beam angle and tr.msducer sizeare specified.

3) Calibration is accomplished on side drilled holes andscanning sensitivity is defined and is consistentwith ASME Code requirements.

4) Evaluation, recording and acceptance standards forflow indications are specified and consistent withthe applicable ASME Code requirements.

No items of noncompliance with regulatory requirements wereidentified.

c. NDE Data Review

The inspector audited preliminary data sheets to ascertain:1) performance of examinations by properly certified person-nel; 2) equipment calibration / checks performed periodically;3) use of specified equipment / procedures; 4) recorded testdata sufficient to provide basis for evaluation; and, 5)evaluation and dispositioning of inspection findings. Re-corded results of visual, surface and volumetric examinations

were audited and included the following wolds:

5

-- FW-5928 Feedwater System

-- FW-5931 Feedwater System

-- SW-MU-2-19-3 Service Water System

JCPD-9 Liquid Poison--

-

-- JCPD ,10 Liquid Poison

2-563-A Reactor Pressure Vessel Weld--

-- 2-563-B Reactor Pressure Vessel Weld

-- 2-563-C Reactor Pressure Vessel Weld

-- 3-563 Reactor Pressure Vessel Weld

The records indicated that examinations had been conductedin accordance with procedural requirements. Examinationresults were documented sufficiently to provide a basisfor proper evaluation.

No items of noncompliance with regulatory requirements wereidentified.

d. Material /Eauipment Certifications

The inspector audited the calibration records associated withUT equipment used to volumetrically examine material / pipingwelds. Records of equipment identified with serial number040-974 and transducers numbers CM-0216, CM-026 and P651were reviewed. The records indicated that this equipmenthad been checked for amplitude, linearity, sensitivity andresolution and records were signed by certified personnel.Additionally, frequency spectrum and waveform analysis recordswere checked for the UT transducers. Also, the inspectoraudited design drawings / associated data for UT calibrationstandards. These data indicated that the materials of con-struction and design were consistent with the ISI Programrequirements. The inspector also audited material certifi-cates for penetra:.t examination materials for batch numbers7C-035, 7C-0051 and 01030. These records indicated thatmaterials were tested for residual halogens / sulphur and hadmet ASME Code requirements.

No items of noncompliance with regulatory requirements wereidentified.

e. NDE Personnel Certifications

The inspector reviewed the UTL's NDE Personnel Trainingand Qualification Manual, and the licensee's SpecificationQA-1000, Revision 4, titled, " Nondestructive ExaminationServices" for compliance with the requirements of SNT-TC-1A,(the applicable document).

Requirements that must be met by NDE contractors are stipu-lated in QA-1000. The contractors (UTL's) Training andQualification Manual specifies the amount and type oftraining an individual receives prior to certification andrequirements an individual must meet before he is certified.

Records of certified examiners were audited by the inspector,and were found to meet the requirements of the beforementioneddocuments.

No items of noncompliance with regulatory requirements wereidentified.

3. Licensee Event No. 78-21/IP

The licensee reported this occurrence (crack in the core spraysparger) to the NRC on October 18, 1978. The inspectorreviewed results of the sparger inspection which were recordedon video tape. The inspection disclosed a crack in the corespray sparger piping of system II. The crack is at anazimuth location of 2080 in the reactor vessel. The crackappears to extend, at least,1800 circumferentially aroundthe pipe on the inlet side of the sparger support bracket.Inaccessibility precludes a complete peripheral inspection ofthe sparger in the area of the crack. However, tests confirmedthat a portion of the crack extended through the pipe wall. Thelicensee in consulting with the NSSS (General Electric) to determinethe cause of failure. Further investigation of the crack andanalysis of the consequences is underway and will provide for amore firm analysis of the occurrence. Corrective action willbe based on the conclusions of the aforementioned evaluation.The licensee is preparing a formal report documenting results ofevaluation and proposed corrective action which will be submittedto the NRC.

No items of noncompliance were identified.

4. Exit Interview

The inspector met with the licensee's representatives, asterisked inparagraph 1, at the conclusion of the inspection on October 27, 1978.
