- Attended exit interview Inservice Inspection (ISI)
The inspector reviewed documents and records, and observed activities, as indicated below, to determine whether ISI was being conducted -in accordance with applicable procedures, regulatory requirements, and licensee commitments.
The applicable code for ISI, for the plant is the American Society of Mechanical Engineers Boiler and Pressure Vessel (ASME BRPV)
Code,Section XI, 1983 Edition with Addenda through Summer 1983 (83S83)
.
The plant has completed the fourth fuel cycle, and is in the second outage of the second 40 month period, of the first ten year ISI interval
(I1,P2,02).
The plant received its operating license January 12, 1987 and commenced commercial operations on May 2,
1987.
The licensee has contracted with Nuclear Energy Services Inc (NES) to perform liquid penetrant (PT),
magnetic particle (MT), and ultrasonic (UT) examinations under the umbrella of the NES Quality Assurance (QA)
program.

The inspector also reviewed completed ultrasonic data of welds where recordable indications had been detected to determined if the indications were properly interpreted and dispositioned.
The inspector also reviewed baseline data of the welds to determine whether the indications were previously recorded and if so, were there any noticeable differences in the recorded information.
Records for the following welds were reviewed:
Examination Records Examined Weld No.

QAA/0022-90-04 dated 10/19/90,
"Harris Nuclear Project Maintenance Program".
In addition the inspector reviewed the surveillance reports for NDE activities conducted during Refueling Outage 3.
The licensee conducted 19 MT,
PT and
UT examinations during
RF03 but only conducted 10 UT surveillances.
As plants age the importance of surface inspections increases because of the increased likelihood of component failure by fatigue.
the licensee should consider conducting some surveillances in the surface examination area.
Within the areas examined, no violations or deviations were identified.

NRC Generic Letter (GL) 89-08:
"Erosion/Corrosion-Induced Pipe Wall Thinning" This GL requested licensees to provide assurances that a long term Erosion/Corrosion (E/C) monitoring program, has been established to ensure that E/C does not lead to degradation of carbon steel piping in single and two phase high energy piping systems.
The licensee has established an E/C inspection program which uses the CHECMATE EPRI (Electric Power Research Institute) computer'rogram, industry experience, and previous inspection data as predictive tools for determining and prioritizing inspection locations.
The licensee's CHECMATE electronic model for the seven chosen piping systems is complete.
Currently the licensee is not using the T-Dat portion of the CHECKMATE program.
The program is implemented by CPEL procedure ISI-107,
"HNP Flow Accelerated Corrosion (FAC) Monitoring Program".
The inspector reviewed the licensee's program, examined marked grids, observed data collection, interviewed licensee personnel and reviewed inspection data and calculations to evaluate the licensee's E/C program.
Observations/Findings The inspection sample is selected on an outage by outage basis, based on the data from previous outages.
The licensee has tested approximately 350 test locations.
Of these, 155 have been inspected more than once.
During this outage, RFO4, the licensee intends to test 182 locations.
As a result of the Erosion
/Corrosion Program the licensee has replaced

.Title I
SHNPP Erosion/Corrosion Program HNP Flow Accelerated Corrosion (FAC) Monitoring Program Digital Ultrasonic Thickness Measurement (Panametrics Model 26DL Plus)
For Erosion/Corrosion Detection and Monitoring'ridding Of Components For Erosion/Corrosion The gridding layout scheme used by the licensee is consistent with the EPRI CHECMATE recommendations with the following exceptions:
P Approximately 10% to 15~ of the total test locations on elbows were established prior to the EPRI recommendations and differ in that they have uniform square blocks vice trapezoidal blocks.
The licensee intends to maintain that scheme for those fittings to assure trending continuity.
.Procedure ISI-107 makes no special provisions for diffusers and expanding elbows.
EPRI CHECMATE manual Appendix A, recommends that an area of two pipe diameters upstream of those fittings be tested.
This recomendation is based on EPRI test data which indicates that E/C can occur upstream of diffusers and expanding elbows..
ISI-107, R3, paragraph Nos. 3.6 and 5.5.1 require contractor to perform applicable ultrasonic examinations in accordance with the. requirements of Attachment 6.6.
Attachment 6.6 addresses the technique requirements for the Panametrics Model 26 DL thickness gauge.
The licensee is currently using the Panametrics Model 26DL Plus in accordance with procedure NDEP-427.
Although the Panametrics Model 26DL Plus is an improvement and its accompanying procedure NDEP-427 has been approved by a CP&L UT Level III, the licensee failed to make any administrative provisions authorizing the use of NDEP-427.
The above is corrected in ISI-107 R4, which was issued expeditiously
after the inspector discussed. this matter with the licensee.
'Not withstanding the above,'t appears that the licensee has established an effective program to maintain high energy carbon steel piping systems within'ode allowable wall thickness limits; b.
NRC Information Notice (IN) 88-48:
"Licensee Report of Defective Refurbished Valves" In this IN and the two associated supplements, the staff discussed a problem identified by Pacific Gas and Electri.c Company (PGEE)
when a counterfeit valve was installed in a non-safety related (NSR) system.
The licensee (PGRE) believed the valve was manufactured by Heniy Vogt Company.
The licensee performed a record review and determined that;they had'ot bought any refurbished SR or NSR valves from the listed suppliers.
It should be noted that this information was obtained by interviews with licensee personnel, as the licensee had not documented well their actions in regards to thi's issue.
The licensee indicated that they would amend their package to better address this issue.
The licensee has taken appropriate action in response to this IN.
C.
NRC Information Notice (IN) 91-31:
"Nonconforming Magnetic Particle (14AM) Prepared Bath" This IN transmitted a Magnaflux Notice which recalled three batches of 14AM MT aerosol prepared bath, and included a warning for six others.
The licensee reviewed their records and determined that the Harris site has never received any of the material identified in the IN.
The licensee has taken appropriate action in response to this IN.
In the areas inspected, no violations or deviations were identifie Cl
Exit Interview The inspection scope and results were summarized on September 25, 1992, with those persons indicated in paragraph 1.
The inspector described the areas inspected.
Although reviewed during this inspection, proprietary information is not contained in this report.
Dissenting comments were not received from the licensee.
