SUBJECT: INSERVICE INSPECTION ACTIVITIES INSPECTION FEEDER | |||
FOR SALEM UNIT 1, INSPECTION REPORT | |||
05000272/2010003, REVISION OF July 21, 2010 | |||
The enclosed feeder contains input for the subject report resulting from inspection of Inservice | |||
Inspection (ISI) activities during the period from April 5, 2010 to June 28, 2010, at Salem Unit 1. | |||
The inspection was conducted using Inspection Procedure 71111.08, Inservice Inspection | |||
Activities and Temporary Instruction (TI) 2515/172, Reactor Coolant System Dissimilar Metal | |||
Butt Welds. The results of this inspection were presented to Mr. Ed Eilola, Salem Plant | |||
Manager, at an exit meeting on June 28, 2010. | |||
Suggested Cover Letter Input | |||
This feeder documents one NRC-identified finding of very low safety significance (Green). This | |||
finding was determined to be a violation of an NRC requirement. This feeder also documents a | |||
licensee-identified violation, which was determined to be of very low safety significance, in | |||
section 40A7 of this report. Because these violations are of very low safety significance and | |||
because the issues were entered into your corrective action process, these findings are being | |||
treated as non-cited violations (NCVs) consistent with Section VI.A.1 of the NRC Enforcement | |||
Policy. | |||
Issue of Agency Concern: Buried, Safety Related Piping: | |||
Because of an ongoing issue of Agency Concern about the degradation of buried piping, this | |||
issue is being documented as a licensee-identified finding in Section 40A7, in accordance with | |||
the guidance of IMC 0612-10. | |||

No specific action is needed for this concern in light of industry initiatives on buried piping and | |||
the NRC Buried Piping Action Plan. | |||
Since this issue, as noted below, is licensee identified, a long discussion was not permitted by | |||
IMC0612 format requirements. Documenting an issue of agency wide concern appears to only | |||
apply to minor findings, however, this issue is more than minor and licensee identified. | |||
The following finding of very low safety significance was identified by PSEG and is a violation of | |||
10 CFR 50, Appendix B, Criterion III, Design Control, an NRC requirement. PSEG did not | |||
providean effective protective coating for the buried AFW piping. This issue has been r~ | |||
evaluated via IMC 0609, Attachment 4, Initial Screening and Characterization of Findings and | |||
IMC 0612, Appendix B, Issue Screening. | |||
During a planned excavation and inspection of the Unit 1 AFW buried piping to SG #12 and SG | |||
#14, PSEG identified corrosion (significantly below minimum wall thickness for a design | |||
pressure of 1950 psi) of the safety related, ASME Class 3, Seismic Class 1 piping. PSEG | |||
repaired or replaced the affected Unit 1 buried AFW piping before returning the plant to | |||
operation. Portions of the Unit 1 and Unit 2 Auxiliary Feedwater (AFW) System piping is buried | |||
piping and has not been visually inspected since the plant began operation in 1977 for Unit I | |||
and since 1979 for Salem Unit 2. In April 2010, approximately 680 ft. (340 ft. of the #12 SG | |||

SUBJECT: INSERVICE INSPECTION ACTIVITIES INSPECTION FEEDER
FOR SALEM UNIT 1, INSPECTION REPORT
05000272/2010003, REVISION OF July 21, 2010
The enclosed feeder contains input for the subject report resulting from inspection of Inservice
Inspection (ISI) activities during the period from April 5, 2010 to June 28, 2010, at Salem Unit 1.
The inspection was conducted using Inspection Procedure 71111.08, Inservice Inspection
Activities and Temporary Instruction (TI) 2515/172, Reactor Coolant System Dissimilar Metal
Butt Welds. The results of this inspection were presented to Mr. Ed Eilola, Salem Plant
Manager, at an exit meeting on June 28, 2010.
Suggested Cover Letter Input
This feeder documents one NRC-identified finding of very low safety significance (Green). This
finding was determined to be a violation of an NRC requirement. This feeder also documents a
licensee-identified violation, which was determined to be of very low safety significance, in
section 40A7 of this report. Because these violations are of very low safety significance and
because the issues were entered into your corrective action process, these findings are being
treated as non-cited violations (NCVs) consistent with Section VI.A.1 of the NRC Enforcement
Policy.
Issue of Agency Concern: Buried, Safety Related Piping:
Because of an ongoing issue of Agency Concern about the degradation of buried piping, this
issue is being documented as a licensee-identified finding in Section 40A7, in accordance with
the guidance of IMC 0612-10.
'_ý'

No specific action is needed for this concern in light of industry initiatives on buried piping and
the NRC Buried Piping Action Plan.
Since this issue, as noted below, is licensee identified, a long discussion was not permitted by
IMC0612 format requirements. Documenting an issue of agency wide concern appears to only
apply to minor findings, however, this issue is more than minor and licensee identified.
The following finding of very low safety significance was identified by PSEG and is a violation of
10 CFR 50, Appendix B, Criterion III, Design Control, an NRC requirement. PSEG did not
providean effective protective coating for the buried AFW piping. This issue has been r~
evaluated via IMC 0609, Attachment 4, Initial Screening and Characterization of Findings and
IMC 0612, Appendix B, Issue Screening.
During a planned excavation and inspection of the Unit 1 AFW buried piping to SG #12 and SG
- 14, PSEG identified corrosion (significantly below minimum wall thickness for a design
pressure of 1950 psi) of the safety related, ASME Class 3, Seismic Class 1 piping. PSEG
repaired or replaced the affected Unit 1 buried AFW piping before returning the plant to
operation. Portions of the Unit 1 and Unit 2 Auxiliary Feedwater (AFW) System piping is buried
piping and has not been visually inspected since the plant began operation in 1977 for Unit I
and since 1979 for Salem Unit 2. In April 2010, approximately 680 ft. (340 ft. of the #12 SG
AFW supply and 340 ft. of the #14 SG AFW supply) of piping between the pump discharge
manifold and the connection to the Main Feedwater piping to the affected SGs was discovered
to be corroded to below minimum wall thickness (0.278") for the 1950 psi design pressure of the
AFW System. The lowest wall thickness measured in the affected piping was 0.077".
Preliminarily, PSEG representatives believe that there was an inadvertent omission of coating
during construction days. PSEG plans on excavating the Unit 2 buried piping to inspect the
condition during the next Unit 2 outage scheduled for the spring of 2011. Although no leakage
was evident for these conditions, the inspector questioned if periodic pressure test had been
conducted on this underground piping and this resulted inan NRC identified finding, as noted in
this feeder, along with an operability determination for Unit 2 and as risk assessment for waiting
to do the above noted inspection. This analysis resulted in a revised pipe design rating for
Unit 2 down to 1275 psig.
10 CFR 50, Appendix B, Criterion 11,Design Control, states, in part, "Measures shall be
established to assure that applicable regulatory requirements and the design basis ... for
those structures, systems, and components to which this appendix applies are correctly
translated into specifications, drawings, procedures, and instructions. These measures shall
include provisions to assure that appropriate quality standards are specified and included in w
design documents and that deviations from such standards are controlled. Measures shall also
be established for the selection and review for suitability of application of materials, parts,
equipment, and processes that are essential to the safety-related functions of the structures, ~'
systems and components."

Contrary to these requirements, PSEG did not provide engineering evaluations, vendor
certification, or testing data to demonstrate that the specified coating would protect the buried
AFW piping for the design lifetime of the plant. Also, PSEG did not assure appropriate quality
standards which assure that deviations from such standards were controlled. Additionally,
PSEG did not provide measures for the selection and review for suitability of the coating
materials for the buried AFW piping application, for periodic inspections to ensure that the.
applied coating was protecting the buried AFW piping, and did not provide engineering details I; -*
demonstrating the ability of the coating to protect the buried AFW piping for the design life of the , ,.
plant.Ad ua
This licensee identified finding affects the mitigating systems cornerstone by affecting the
secondary, short term decay heat removal capability. Because the finding did not result in loss .,
of operability or functionality the inspector determined that the finding was of very low safety
significance, Green. The inspector determined that this licensee identified finding is more than
minor, and that a Cross Cutting Aspect did not exist because the issue was not indicative of
current performance because the condition existed since 1977. Specifically, the section of * ,
piping under question was identified with degradation that put the system outside its originalf, /
design basis (1950 psi design rating); and PSEG was required to make significant revisions to
the system design analysis to take credit for available margin to show that the system remained -
operable. "
.:
Because PSEG entered this condition into the corrective action process (Notification 20456999) .:
and because the issue is of very low safety significance (Green), this issue is being treated as a : .. ..
licensee identified non-cited violation consistent with Section VI.A. 1 of the NRC Enforcement :',,. ,'
Policy.
Follow up Comments for Future PI&R Sample
Because PSEG had not completed the EQ:ACE for the corroded AFW piping, had not ! l >2
completed the Root Cause Evaluation for missing the IWA-5244 pressure tests, and had not
completed it's evaluation of Notification 20462034, it was agreed that an annual PI&R sample
would be completed to review these documents to determine that the following .
comments/observations have been addressed by PSEG. It is anticipated that this sample will >
be performed in September 2010 depending upon PSEG completion of the cause ,
determinations and Notification actions.
The inspector made other observations related to the finding on the AFW pressure testing issue * .-
and degradation noted in the AFW yard piping. PSEG intends to address the following
observations/comments in the cause determinations and Notification evaluations.*,
(1) The PSEG buried piping inspection procedure did not document how a representative
inspection sample is selected and did not enumerate the basis for the inspection sample I

REPORT DETAILS
1R08 Inservice Inspection (ISI) (7111108- 1 Sample)
a. Inspection Scope
The inspector observed a selected sample of nondestructive examination (NDE)
activities in process. Also, the inspector reviewed the records of selected additional
samples of completed NDE and repair/replacement activities. The sample selection was
based on the inspection procedure objectives and risk priority of those components and
systems where degradation would result in a significant increase in risk of core damage.
The observations and documentation reviews were performed to verify that the activities
inspected were performed in accordance with the American Society of Mechanical
Engineers (ASME) Boiler and Pressure Vessel Code requirements.
The inspector reviewed the licensee's performance of a visual inspection (VT) of the Unit
1 reactor vessel closure head (RVCH) and the installed upper head penetrations. The
inspector reviewed the visual procedure, the qualifications of the personnel and j ~,
reviewed the inspection report documenting the inspection results. The inspector also
reviewed the data sheets for the penetrant tests completed on three of the penetration
The inspector reviewed records for ultrasonic testing (UT), visual testing (VT), penetrant
testing (PT) and magnetic particle testing (MT) NDE processes. PSEG did not perform
any radiographic testing (RT) during this outage. The inspector reviewed inspection ~ ~
data sheets and documentation for these activities to verify the effectiveness of the
examiner, process, and equipment in identifying degradation of risk significant systems,
structures and components and to evaluate the activities for compliance with the
requirements of ASME Code,Section XI.

The inspector reviewed PSEG's efforts in identifying wear degradation to the tubing in
the four SGs at Unit 1. The majority of the identified wear indications were attributed to
anti vibration bar (AVB) wear in the u bend regions of the four SGs. The inspector
reviewed the analyses and evaluations that determined that a total of 14 SG tubes would
be removed from service by plugging.
Boris Acid Corrosion Control Program Activities
The inspector reviewed the PSEG boric acid corrosion control program. The resident
inspectors observed PSEG personnel performing boric acid walkdown inspections,
inside containment, and in other affected areas outside of containment, at the beginning
of the Unit 1 refueling outage. The inspectors reviewed the notifications generated by
the walkdowns and the evaluations conducted by Engineering to disposition the
notifications. Additionally, the inspector reviewed a sample of notifications and
corrective actions completed to repair the reported conditions.
Section XI Repair/Replacement Samples:
AFW System Piping, Control Air & Station Air: The inspectors reviewed PSEG's
discovery, reporting, evaluation and the repair/replacement of Unit 1 AFW piping that
was excavated for inspection during the April 2010 Unit 1 refueling outage (1R20).
PSEG conducted this inspection in accordance with PSEG's Buried Piping Inspection
Program. Additionally, the inspectors reviewed the UT testing results (approximately
20,000) performed to characterize the condition of the degraded Unit 1 buried AFW
piping.
The inspector also reviewed the repair/replacement work orders and the 50.59 screening
and evaluation for the AFW, CA and SA piping. The inspectors reviewed the fabrication
of the replacement piping, reviewed the' documentation of the welding and NDE of the
replacement piping and reviewed the pressure tests used to certify the replacement
piping. Additionally, the inspector reviewed the specified replacement coating, the
application of the replacement coating and the backfill of the excavated area after the
- piping had been tested.
The inspector reviewed the finite element analysis (FEA) results from PSEG's past
operability analysis on the affected Unit 1 buried AFW piping completed by the licensee
in order to demonstrate past operability at a reduced system pressure of 1275 psig. The
design pressure of the AFW system is 1950 psig.
The inspector also reviewed the UT testing results (approximately 400) performed on
- i4porbtons of the Unit 2_AFWpiping in response to the conditions observed on Unit . "_men__4]__tlleleetht_"0at_
1 piping in order to determine if significant degradation existed on the Unit 2 buried AFW . ,..
piping.
Reiectable Indication Accepted For Service After Analysis:
The inspector reviewed the Notification and the UT data report of a rejectable wall
thickness measurement on the #11 SG Feedwater elbow during 1 R20. The inspector
reviewed the additional wall thickness data taken to further define the condition and
3
reviewed the finite element analysis (FEA) which verified that sufficient wall thickness
remained to operate the component until the next refueling outage when it will be
replaced.
b. Finding
The inspector identified the following violation related to ASME,Section XI testing of
buried Unit I and Unit 2 buried AFW piping.
introduction. The inspector identified a GREEN non-cited violation (NCV) of 10 CFR
50.55a(g)(4) and the referenced American Society of Mechanical Engineers (ASME)
Code,Section XI, paragraph IWA-5244 for PSEG's failure to perform required pressure
tests of buried components. This piping is safety related, 4.0" ID, ASME Class 3,
Seismic Class 1 piping.
Description. Portions of the Unit I and Unit 2 Auxiliary Feedwater (AFW) System piping
is buried piping and has not been visually inspected since the plant began operation in
1977 for Unit 1 and since 1979 for Salem Unit 2. In April 2010, approximately 680 ft.
(340 ft. of the #12 SG AFW supply and 340 ft. of the #14 SG AFW supply) of piping
between the pump discharge manifold and the connection to the Main Feedwater piping
to the affected SGs was discovered to be corroded to below minimum wall thickness
(0.278") for the 1950 psi design pressure of the AFW System. The discovery was noted
by PSEG during a planned excavation implementing their buried pipe inspection
program. The lowest wall thickness measured in the affected piping was 0.077". PSEG
plans on excavating the Unit 2 buried piping to inspect the condition during the next
Unit 2 outage scheduled for the spring of 2011. The affected Unit 1 piping was replaced.
Although no leakage was evident for these conditions, the inspector questioned if
periodic pressure tests had been conducted on this underground piping.
10 CFR 50.55(a)(g)(4)(ii) requires licensees to follow the in-service requirements of the
ASME Code,Section XI. Paragraph IWA-5244 of Section Xl requires licensees to

Contrary to these requirements, PSEG did not perform the required pressure tests of the 'rcMmendddetj~ addressF
my
buried AFW piping to the #12 SG and #14 SG at Salem Unit 1 during the 2nd In Service
Inspection Interval (2/27/88 to 5/19/01) and during the 1st (5/19/01 to 6/3/04) and 2 nd
(6/24/04 to 5/20/08) periods of the 3rd In Service Inspection Interval (5/19/01 to 5/19/11).
Also, contrary to these requirements, PSEG did not perform the required pressure tests
of the buried piping to the #22 SG and #24 SG for Unit 2 for the 1st period (5/19/01 to
6/3/04) and 2nd period (6/24/04 to 5/20/08) of the 3rd In Service Inspection Interval.
Consequently, from 2/27/88 to 4/20/07) the required pressure tests were not performed
to demonstrate structural integrity on the affected buried-Unit 1 AFW piping.
Because PSEG entered this condition into the corrective action process (Notification
20459686) and because it is is of very low safety significance (Green), it is being treated
as a non-cited violation consistent with Section VI.A.1 of the NRC Enforcement Policy.
NCV 50-272/2010-?? and NCV 50-311/2010-??
40A2 Identification and Resolution of Problems (71152)
a. Inspection Scope
The inspectors reviewed a sample of corrective action reports (notifications), listed in
Attachment 2 which involved in-service inspection related issues, to ensure that issues
are being promptly identified, reported and resolved.
b. Findings
No findings of significance were identified.
40A5 Temporary Instruction (TI) 2515/172
a. Inspection Scope
The Temporary Instruction (TI), 2515/172 provides for confirmation that owners of
pressurized-water reactors (PWRs) have implemented the industry guidelines of the
Materials Reliability Program (MRP) -139 regarding nondestructive examination and
evaluation of certain dissimilar metal welds in the RCS containing nickel based Alloys
600/82/182.
6
During 1R20 PSEG inspected the dissimilar metal weld on the 1" reactor vessel drain
piping with no detected indications. Salem Unit 1 has dissimilar metal welds in the eight
reactor coolant system piping to reactor vessel nozzle safe end welds. No additional
inspections or MSIP applications were performed during 1R20.
This TI requires documentation of specific questions in an inspection report. The
questions and responses for the IR 05000272/2010003 section 40A5 are included in
this report as Attachment "B-I".
b. Findings
No findings of significance were identified.
40A6 Meetings, includinq Exit
The inspectors presented the ISI inspection and TI 2515/172 inspection results to Mr. Ed
Eilola, Salem Plant Manager, and other members of the PSEG staff at the conclusion of
the inspection at an exit meeting on June 28, 2010 for Salem Unit 1. The licensee
acknowledged the conclusions and observations presented. Some proprietary
information was reviewed during this inspection and was properly destroyed. No
proprietary information is contained in this report.
40A7 Licensee Identified Violations
The following violation of NRC requirements was identified by PSEG. It was determined
to have very low significance (Green) and to meet the criteria of Section VI of the NRC
Enforcement Policy, NUREG-1600, for being dispositioned as a non-cited violation.
The f*llowing finding of very l.w safcy was identified by PSEG. The finding
.igifi.a...
is a violation of 10 CFR 50, Appendix B, Criterion III, Design Control that-requires in part
that measures shall be established to assure that applicable regulatory requirements
and'design bases are correctly translated into specifications, drawings, and instructions
and that these measures shall include provisions to assure the proper selection and
review for suitability of application of materials, parts, equipment, and processes. During
pipe excavation and inspections conducted as part of PSEGs buried piping program
PSEG identified that it did not provide an effective protective coating for the buried_
section of AFW piping on Unit 1.
PSEG identified general corrosion that reduced the wall thickness of the safety related
piping to less than the design minimum wall thickness of 0.278" for the system design
pressure of 1950 psig. The lowest measured wall thickness was 0.077". An FEA for the
degraded piping was able to demonstrate past operabili at a reduced operating
pressure of 1275 psiortogt~i

20456999) and because the issue is of very low safety significance (Green), this issue is
being treated as a non-cited violation consistent with Section VI.A.1 of the NRC
Enforcement Policy. NCV 50-27212010003-??

Materials Reliability Program (MRP) -139 regarding nondestructive examination and
evaluation of certain dissimilar metal welds in the RCS containing nickel based Alloys ~fr ~

600/82/182. This TI requires documentation of specific questions in an inspection report.
The questions and responses for MSIP for the IR 05000311/2009005 section 40A5 are
included in this Attachment "B-i".
In summary the Salem Units 1 and 2 have MRP-139 applicable Alloy 600/82/182 RCS

TI 2515/172 reauires the followina a uestions to be answered for MRP-139 MSIP inspections:
Question 1: For each mechanical stress improvement used by the licensee during the Salem U1
1R20 outage, was the activity performed in accordance with a documented qualification report """V ~K$~2':~"A"'~
for stress improvement processes and in accordance with demonstrated procedures?
Response Question 1: No MSIP activities were conducted on UI during 1R20.
Question d.l: Are the nozzle, weld, safe end, and pipe configurations, as applicable, consistent
with the configuration addressed in the stress improvement (SI) qualification report?
Response- Question d.l: No MSIP activities were conducted on U1 during 1R20.
Question d.2.: Does the SI qualification report address the location radial loading is applied, the
applied load, and the effect that plastic deformation of the pipe configuration may have on the
ability to conduct volumetric examinations?
Response Question d.2: No MSIP activities were conducted on U1 during 1R20.
Question d.3.: Do the licensee's inspection procedure records document that a volumetric
examination per the ASME Code,Section XI, Appendix VIII was performed prior to and after the
application of the MSIP?
Response: Question d.3.: No MSIP activities were conducted on U1 during 1 R20.
A-1 5
Question d.4.: Does the SI qualification report address limiting flaw sizes that may be found
during pre-SI and post-SI inspections and that any flaws identified during the volumetric
examination are to be within the limiting flaw sizes established by the SI qualification 5'
report?

Response: Question d.4.: No MSIP activities were conducted on U1 during 1 R20.
Question d.5.: Was the MSIP performed such that deficiencies were identified, dispositioned,
and resolved?

I think that we missed the point here. As defined in MC 0612 a performance deficiency is an issue that is
the result of a licensee not meeting a requirement or standard where the cause was reasonably within
the licensee's ability to forsee and correct, and therefore should have been prevented. PSEG did not
meet the CFR because they did not perform the testing, not the other way around. What was the
result/the impact on the safety of the public by not performing the required testing? It is necessary to
define thise result in order to evaluate the significance - that is why the definition is written that way. Not
using the following words exactly one suggestion for defining the result would be - due to the condition of
the pipe and coating identified during the excavation, it is clear that the failure to perform required testing
would have ultimately resulted a loss of structural integrity for the pipe impacting the operability of the
affected AFW trains.
Needs to address all the
