  +
examination. '
  +
The inspector observed LMT personnel performing pre-cleaning of the welds W-2
  +
and W-22, applying the dye penetrant with the appropriate dwell times, and
  +
claaning and applying the developer for interpreting the exam results in accordance !
  +
with procedure ISI-PT-1, " Solvent Removable, Visible Dye Penetrant Examination," '
  +
Revision 10. LMT personnel were well prepared with materials staged near the
  +
work site and encountered no difficulties with the examinations. Additionally, these
  +
ISI examinations were within the same area and puformed simultaneously, which
  +
demonstrated good as low as reasonably achievable (ALARA) radiological work
  +
practices. No relevant indications were detected.
  +
LMT personnel performed visual inspection of hangers H-3 and H 5, which included
  +
hand tightness checks of anchor bolting and visual observation of the entire hanger
  +
against the component support assembly drawing for missing parts, cracked welds
  +
bolt alignment, thread engagement and proper fit,in accordance with procedure ISI-
  +
VT-2.0, " Visual Examination of Components and Their Supports," Revision 7. No
  +
discrepant conditions were identified.
  +
LMT personnel performed wet fluorescent MT of a reactor vessel head stud. The
  +
LMT personnel performed the verification of the fluorescent particle concentration,
  +
correctly checked the magnetic field strength using a pie gage, and performed this
  +
examination in accordance with procedure ISI-MT-2, " Wet Magnetic Particle
  +
['
  +
Examination," Revision 8. No relevant indications were identified.
  +
LMT personnel performed remote underwater visual examination of the upper core
  +
intemal structure. The LMT personnel performed the camera setup, calibration
  +
check (resolve 1/32" line on 18 percent neutral gray card), and examination in
  +
accordance with procedure ISI-VT 5.0, " Visual Examination of Prairie Island Reactor
  +
Vessel Interior," Revision 2. The on-site ISI program engineer and Authorized
  +
Nuclear Inservice Inspector observed this activity, which indicated active contractor
  +
oversight. No rejectable indications were identified.
  +
LMT personnel performed automated UT on the reactor vessel head weld W-6. For
  +
this examination, inspectors verified that scan parameters / equipment, which
  +
included scanning level gain settings, scanning speeds, scanning increments, >
  +
transducer angles, calibration block, and transducer frequencies were in accordance
  +
with procedure IDI-UT-3A, " Ultrasonic Examination of Reactor Vessel Welds,"
  +
Revision 6. The LMT personnel demonstrated knowledge of the examination being
  +
perform by comparing the location and amplitude response of previously recorded
  +
indications related to weld geometry. LMT personnel were able to spend much of
  +
this examination within a low dose area, which demonstrated good ALARA
  +
radiological work practices, due to the use of remote controlled automated UT
  +
equipment. No Code reportable indications were detected.
  +
The inspector reviewed LMT personnel qualification and certification records and
  +
determined that they met the American Society for Nondestructive Testing

The inspector reviewed the ISI procedures used for the examinations observed and
  +
determined that the procedures met the ASME Code,1989 Edition, Section XI and
  +
Section V requirements. These procedures had been reviewed and accepted by the i
  +
Authorized Nuclear Inservice Inspector. '
  +
Overall, the inspector observed good preplanning, preparation, and demonstrated
  +
knowledge of the examinations performed, which resulted in ALARA radiological
  +
work practices.
  +
Unit 2 SG ET executed well
  +
The inspector reviewed the scope of the Unit 2 SG tube ET inspection which
  +
included:
  +
* 100 percent full tube length bobbin inspection (except the row one and two
  +
U-bend region).
  +
* 100 percent hot-leg side tubesheet inspection using a motor rotating
  +
pancake coil probe (MRPC) including existing F* re-roll locations. This probe
  +
contained a + Point * coil, a 0.115 diameter pancake coil, and a 0.080
  +
diameter pancake coil.
  +
e 20 percent cold-leg side tubesheet inspection using a MRPC probe.
  +
t
  +
* 100 percent of row one and two U bends with a MRPC probe (contained a
  +
+ Point coil).
  +
e 100 percent of all dented locations (greater than 5 volts) with a MRPC
  +
probe.
  +
e Hot-leg side inspection of B&W mechanical plugs with a MRPC probe
  +
I (contained a + Point coil).
  +
I
  +
The inspector determined that this inspection scope exceeded the technical
  +
specification requirements and licensee commitments to generic letter (GL) 95-03
  +
"Circumferential Cracking of Steam Generator Tubes." In addition, the licensee
  +
l staff chose to use probes containing the + Point * coil for the B&W plua
  +
1
  +
inspections and on the cold-leg side of the tubesheet, which had reporc 'y not
  +
been done before. The ET program engineer stated that he felt that the i .)oint*
  +
coil provided the best possible inspection of these areas. As a result of ET
  +
inspections using a rotating + Point * coil, three B&W mechanical plugs in tubes on
  +
the hot-leg side of SG-22 were identified with circumferentially oriented indications.
  +
The predominant type of ET indications detected were axial oriented inside diameter
  +
indications located at the SG tube roll expansions on the hot-leg side of the SG.
  +
This mode of degradation is consistent with past ET inspections and was indicative

%
  +
of primary water stress corrosion cracking. The ET performed consistently
  +
detected previously identified tube imperfections such as cold leg tube thinning,
  +
. tube wear, and manufactured burnish marks at the expected locations, which
  +
indicated an effective inspection.
  +
The inspector observed Rockridge Technologies personnel performing ET data
  +
acquisition for the Unit 2 SG tubes and B&W tube plugs. The inspector verified
  +
that the ET equipment setup parameters, methodology and equipment used were in
  +
accordance with procedure 42-EC-248, "Multifrequency Eddy Current Procedure
  +
Steam Generator Tubing Digital Eddy Current System Prairie Island, Units 1 & 2,"
  +
Revision 2. The ET equipment and techniques used for the tube inspection were
  +
consistent with qualified techniques per Appendix H of EPRI-NP-6201, "EPRI PWR
  +
Steam Generator Ext mination Guidelines," Revision 3. The personnel observed
  +
performing ET data acquisition demonstrated conservative inspection techniques
  +
such as frequently verifying the robot positioning tool at the correct tube location
  +
by using the existing tube plugs as reference points.
  +
The ET data analysis was performed by Rockridge Technologies and Zetec
  +
personnel using Zetec Eddynet95 software. ET data analysis was performed by
  +
prianary and secondary analysts located off-site, with the exception of one primary
  +
data analyst and the resolution analysts located on-site. The on-site analysts
  +
performed ET data analysis in accordance with ISI-ET-1.0, " Bobbin Coil Data
  +
Analysis Guidelines," Revision 7, and with ISI-ET-3.0, " Rotating Coi! Data Analysis
  +
Guidelines," Revision 4. The on-site data analysts demonstrated knowledge of the
  +
latest ET data analysis techniques and made conservative clas6fications of
  +
potential SG tube degradation.
  +
The inspector reviewed Zetec and Rockridge Technologies personnel qualification
  +
and certification records and determined that they met the American Society for
  +
Nondestructive Testing Recommended Practice No. SNT-TC-1 A and ASME Code,
  +
1989 Edition, Section XI requirements. Additionally, the ET data analysts had been
  +
qualified to Appendix G of EPRI-NP-6201, "EPRI PWR Steam Generator Examination
  +
Guidelines," Revision 3. These certifications had been reviewed and accepted by
  +
the Authorized Nuclear Inservice inspector.
  +
The inspector reviewed the ISI procedures used for the ET data acquisition and data
  +
analysis and determined that the procedures met the ASME Code,1989 Edition,

Authorized Nuclear Inservice Inspector.
  +
c. Conclusions
  +
The inspector observed good preplanning, preparation, and demonstrated
  +
knowledge of the inservice examinations performed, which resulted in ALARA
  +
radiological work practices. Additionally, the inspector identified the following
  +
steam generator inspection staff decisions which demonstrated the licensee staff
  +
focus on safety:

During a secondary side pressure test of SG 22 a Westinghouse explosively welded ,
  +
plug installed in 1977 was found to have seepage at the primary tubesheet face. ;
  +
Vendor ABB CE was scheduled to remove and replaced this plug with an inconel !
  +
690 welded plug.
  +

  +
The vendor ABB CE removed the remaining Westinghouse mechanical plugs with
  +
heats that had been identified as potentially susceptible to cracking (identified in
  +
NRC Bulletin 89-01 " Failure of Westinghouse Steam Generator Tube Mechanical
  +
Plugs" and NRC informatio'n notice 94-87 " Unanticipated Crack in a Particular Heat
  +
of Alloy 600 Used for Westinghouse Mechanical Flugs for Steam Generator
  +
Tubes"). ABB CE had been tasked by the licensee to replace these 145 plugs with
  +
, inconel 690 rolled plugs. At the conclusion of this inspection, the licensee staff
  +
indicated that they planned to replace the three B&W plugs with circumferentially,
  +
oriented ET indications.
  +
During secondary side pressure testing and visual examination of the SG tubesheet
  +
area, the licensee identified ten tubes in SG-21 and two tubes in SG-22 with
  +
leakage. Each of these tubes had been previously repaired by adding an additional
  +
hard-roll and applying the F* criterion. Only one tube in SG-21 had measurable
  +
, leakage (2 drops per minute) and one tube in SG 22 had measurable leakage (one
  +
'
  +
drop in 3 minutes). The licensee developed an action plan which included:

of selected rerolls, determining the leak rate at main steam line break conditions
  +
with in-situ pressure tests, evaluation of process parameters against the F*
  +
qualification report, and confirming changes in roll transition ET indications after
  +
hydraulic expansion.
  +
On February 5,1997, the Office of Nuclear Reactor Regulation (NRR) staff 1
  +
requested the licensee to resolve NRC staff questions relating to the SG tube ;
  +
leakage implications on the bounding leakage assumed in the qualification reports l
  +
for the F* repair process prior to plant startup. At the conclusion of this inspection ,
  +
on February 13,1997, the licensee staff had met with NRR staff to resolve the I
  +
NRC staff questions.
  +
The licensee staff choose to perform in-situ pressure testing (at main steam line
  +
J
  +
break pressures) to assess the structural and leak tight integrity of the as found 1
  +
condition of 45 F* tubes. The inspector confirmed that this scope included all
  +
leaking tubes which had been identified during the secondary side pressure testing.
  +
At the completion of this inspection the licensee had identified the following
  +
leakage from in-situ pressure testing SG tubes at main steam line break (MSLB)
  +

  +
SG-22 R16C38 0.05-0.11 j
  +
SG-22 R13C46 0.00064
  +
The licensee staff determined that the maximum potentialleak rate under MSLB i
  +
differential pressure conditions could have been 0.53 gallons per minute !
  +
contribution from the total population of 288 F* tubes. The licensee staff had j
  +
planned on installing additional rerolls for each of the F' tubes with measurable l
  +
leakage and had scheduled a secondary side pressure test to ensure that these
  +
tubes were not leaking prior to plant startup.
  +
c. Conclusions
  +
The inspector considered that the licensee actions; to perform in-situ pressure
  +
testing of SG tubes for assessment of the as found integrity, to oromptly put in
  +
place a repair plan and address NRC staff questions related to leaking F* SG tubes, ,
  +
to replace tube plugs with heats susceptible to cracking (without identified l
  +
leakage), demonstrated a steam generator repair program focused on safety. I

removal was impractical. Thus, the inspector was concerned with 73 Code
  +
examinations, which listed limitations (see third period second interval examinations l
  +
q
  +
listed in Attachment A) that prevented meeting the ASME Section XI Code 4
  +
examination requirements, and for which 10 CFR 50.55a(g)(4) requirements of l
  +
" extent practical" may not have been met. If the licensee had submitted relief
  +
requests as required by 10 CFR 50.55a(g)(5)(iii) there would have been NRC
  +
reviews and authorization of the " extent practical."
  +
ASME Code, Section XI,1980 Edition Winter 1981 Addenda, IWB-2500(a) requires
  +
" Components shall be examined and tested as specified in Table IWB-2500-1,"
  +
IWC-2500(a) requires " Components shall be examined and pressure tested as
  +
specified in Table IWC-2500-1 and IWF-2500 requires " Components supports
  +
subject to examination shall be examined and tested as specified in Table IWF-
  +
2500-1."
  +
Contrary to these requirem'ents on February 12,1997, the inspector identified 73
  +
examinations, affecting both units (identified in attachment A as * limited exam") for
  +
which Code examination requirements had not been met and for which authorized
  +
Code relief had not been obtained pursuant to 10 CFR 50.55a(g)(6)(i) and Technical
  +
Specification 4.2.A.1 requirements. Failure to obtain ASME Code relief for these
  +
examinations is considered an additional example of violation (50-282/97003-
  +
01(b);50-306/97003-01(b)). Based on these findings, the inspector considered that
  +
the extent of this problem was programmatic and many additional examinations
  +
existed which required Code relief.
  +
The licensee staff initially stated that A3ME Code requirements for these
  +
examinations or similar examinations were not required to be met, since they were
  +
examined to the extent practical and limited t,; the design, geometry and/or
  +
materials of construction pursuant to 10 CFR 50.55a(g)(4) requirements. However,
  +
10
  +
  +
,
  +
,
  +
at the completion of this inspection during the final phone exit on February 20,
  +
1997, the licensee staff acknowledged this violation and indicated that Monticello
  +
(applicable Technical Specification is 4.15) was in the same condition. The licensee
  +
did not commit to any actions or schedule to address this situation.
  +
Inadeauate Relief Reauest is Denied
  +
On November 1,1995,.the licensee submitted an ASME Code relief request to use
  +
Code Case 521 relating to ASME Code Section XI examination schedule B
  +
requirements for the deferral of inspections of nozzle-to-vessel welds and inside
  +
radius section examinations for both Units. The following chronology of events
  +
transpired relating to this request:
  +
November 20,1995 NRR assigned the review of this relief request to Idaho
  +
National Engineering Laboratory (INEL).
  +
1
  +
December 13,1995 A conference call was held with NRR, INEL, and the
  +
licensee to request additional information to clarify and
  +
support the basis for this relief request.
  +
July 25,1996 The licensee submitted a historical inspection summary, ,
  +
which referred to Westinghouse Report WCAP-10363,
  +
" Handbook on Flaw Evaluation, Prairie Island 1 and 2
  +
)
  +
Reactor Vessels" for justification.
  +
July 29,1996 INEL requested the licensee to provide WCAP-10363.
  +
1
  +
August 9,1996 The licensee submitted WCAP-10363 and a
  +
'
  +
Westinghouse Report WCAP-10562, " Background and
  +
Technical Basis of Handbook on Flaw Evaluation."
  +
November 6,1996 A conference call was held with NRR, INEL, and the
  +
licensee to clarify the information in the current
  +
submittals.
  +
November 8,1996 A conference call was held with NRR, INEL, and the
  +
l
  +
licensee to discuss the licensee's basis for the relief
  +
'
  +
request and in response the licensee committed to I
  +
revise the relief request.
  +
l
  +
November 26,1996 The licensee submitted further information and revised
  +
the basis for its' proposal to exclude the vessel-to-shell
  +
welds; and enhanced the overall basis for this relief
  +
)
  +
request. ]
  +
l
  +
January 7,1997 A Request for Additional Information (RAl) was issued l
  +
by NRR staff to obtain clarification pertaining to the l
  +
licensee's basis for this relief request. I

.
  +
February 6,1997 At the licensee's request, a meeting was held at the
  +
NRC headquarters office to discuss RAI questions and
  +
resolve technical questions associated with this relief
  +
request.
  +
February 7,1997 The technicalissues could not be resolved and NRR
  +
staff denied this relief request and gave the licensee the
  +
option to withdraw this request.
  +
A significant amount of NRC staff resources were involved in attempting to review
  +
thi.s poorly prepared and inadequately based relief request. Although subsequent
  +
submittals improved this relief request, ultimately the technical issues could not be
  +
resolved and the licensee opted to withdraw this relief request.
  +
The inspector reviewed the NRR staff requests for additionalinformation associated
  +
with six relief requests submitted by the licensee as part of the Prairie Island Unit 1
  +
Third 10-Year Intervalinservice Inspection Examination Plan. NRR technical staff
  +
issued requests for additionalinformation on four of the six relief requests
  +
submitted by the licensee. Two relief requests required additional technical
  +
justification, one required specific drawings identifying the areas needing relief, and
  +
one should not have been submitted based on an existing NRC endorsed ASME
  +
Code Case, which bounded the issue.
  +
The inspector reviewed the NRR staff requests for additional information associated
  +
with seven relief requests submitted by the licensee as part of the Prairie Island
  +
Unit 2 Third 10-Year Intervalinservice inspection Examination Plan. NRR technical
  +
staff issued requests for additionalinformation on four of the seven relief requests.
  +
#
  +
Two relief requests required additional technical justification, one required specific
  +
drawings identifying the areas needing relief, and one should not have been
  +
submitted based on an existing NRC endorsed ASME Code Case, which bounded
  +
the issue.
  +
t
  +
c. Conclusions
  +
Because of an inadequately prepared relief request, the NRC staff expended a
  +
significant amount of resources in th9 review of the licensee's relief request to
  +
defer Code mandated examinations associated with the reactor vessel. Although
  +
subsequent submittals improved this relief request, ultimately the technical issues
  +
could not be resolved and the licensee decided to withdraw this relief request. The
  +
inspector identified additional sxamples of relief requests submitted as part of the
  +
licensee's Third 10-Year Interval inservice Inspection Examination Plan, which
  +
lacked detail or an adequate technical basis as originally submitted. The inspector
  +
considered these examples to demonstrate a weakness in the licensee staff's
  +
understanding of the level of detail and technical basis needed to support ASME
  +
Code, Section XI, ISI relief requests.
  +
The inspector identified in excess of 80 examinations which did not meet ASME
  +
Code ISI requirements, without NRC approved Code relief. The inspector
  +
considered this to demonstrate a lack of understanding by the licensee's staff of
  +
regulatory requirements related to Code ISI relief requests.

.

Additionally, the inspector observed the LMT personnel performing the post. ;

examination calibration check. No recordable indications were detected for this i

examination. '

The inspector observed LMT personnel performing pre-cleaning of the welds W-2

and W-22, applying the dye penetrant with the appropriate dwell times, and

claaning and applying the developer for interpreting the exam results in accordance !

with procedure ISI-PT-1, " Solvent Removable, Visible Dye Penetrant Examination," '

Revision 10. LMT personnel were well prepared with materials staged near the

work site and encountered no difficulties with the examinations. Additionally, these

ISI examinations were within the same area and puformed simultaneously, which

demonstrated good as low as reasonably achievable (ALARA) radiological work

practices. No relevant indications were detected.

LMT personnel performed visual inspection of hangers H-3 and H 5, which included

hand tightness checks of anchor bolting and visual observation of the entire hanger

against the component support assembly drawing for missing parts, cracked welds

bolt alignment, thread engagement and proper fit,in accordance with procedure ISI-

VT-2.0, " Visual Examination of Components and Their Supports," Revision 7. No

discrepant conditions were identified.

LMT personnel performed wet fluorescent MT of a reactor vessel head stud. The

LMT personnel performed the verification of the fluorescent particle concentration,

correctly checked the magnetic field strength using a pie gage, and performed this

examination in accordance with procedure ISI-MT-2, " Wet Magnetic Particle

['

Examination," Revision 8. No relevant indications were identified.

LMT personnel performed remote underwater visual examination of the upper core

intemal structure. The LMT personnel performed the camera setup, calibration

check (resolve 1/32" line on 18 percent neutral gray card), and examination in

accordance with procedure ISI-VT 5.0, " Visual Examination of Prairie Island Reactor

Vessel Interior," Revision 2. The on-site ISI program engineer and Authorized

Nuclear Inservice Inspector observed this activity, which indicated active contractor

oversight. No rejectable indications were identified.

LMT personnel performed automated UT on the reactor vessel head weld W-6. For

this examination, inspectors verified that scan parameters / equipment, which

included scanning level gain settings, scanning speeds, scanning increments, >

transducer angles, calibration block, and transducer frequencies were in accordance

with procedure IDI-UT-3A, " Ultrasonic Examination of Reactor Vessel Welds,"

Revision 6. The LMT personnel demonstrated knowledge of the examination being

perform by comparing the location and amplitude response of previously recorded

indications related to weld geometry. LMT personnel were able to spend much of

this examination within a low dose area, which demonstrated good ALARA

radiological work practices, due to the use of remote controlled automated UT

equipment. No Code reportable indications were detected.

The inspector reviewed LMT personnel qualification and certification records and

determined that they met the American Society for Nondestructive Testing

Recommended Practice No. SNT-TC-1 A and the American Society of Mechanical

Engineers (ASME) Code,1989 Edition, Section XI requirements. These

certifications had been reviewed and accepted by the Authorized Nuclear Inservice

Inspector.

,

l

The inspector reviewed the ISI procedures used for the examinations observed and

determined that the procedures met the ASME Code,1989 Edition, Section XI and

Section V requirements. These procedures had been reviewed and accepted by the i

Authorized Nuclear Inservice Inspector. '

Overall, the inspector observed good preplanning, preparation, and demonstrated

knowledge of the examinations performed, which resulted in ALARA radiological

work practices.

Unit 2 SG ET executed well

The inspector reviewed the scope of the Unit 2 SG tube ET inspection which

included:

  • 100 percent full tube length bobbin inspection (except the row one and two

U-bend region).

  • 100 percent hot-leg side tubesheet inspection using a motor rotating

pancake coil probe (MRPC) including existing F* re-roll locations. This probe

contained a + Point * coil, a 0.115 diameter pancake coil, and a 0.080

diameter pancake coil.

e 20 percent cold-leg side tubesheet inspection using a MRPC probe.

t

  • 100 percent of row one and two U bends with a MRPC probe (contained a

+ Point coil).

e 100 percent of all dented locations (greater than 5 volts) with a MRPC

probe.

e Hot-leg side inspection of B&W mechanical plugs with a MRPC probe

I (contained a + Point coil).

I

The inspector determined that this inspection scope exceeded the technical

specification requirements and licensee commitments to generic letter (GL) 95-03

"Circumferential Cracking of Steam Generator Tubes." In addition, the licensee

l staff chose to use probes containing the + Point * coil for the B&W plua

1

inspections and on the cold-leg side of the tubesheet, which had reporc 'y not

been done before. The ET program engineer stated that he felt that the i .)oint*

coil provided the best possible inspection of these areas. As a result of ET

inspections using a rotating + Point * coil, three B&W mechanical plugs in tubes on

the hot-leg side of SG-22 were identified with circumferentially oriented indications.

The predominant type of ET indications detected were axial oriented inside diameter

indications located at the SG tube roll expansions on the hot-leg side of the SG.

This mode of degradation is consistent with past ET inspections and was indicative

,

%

of primary water stress corrosion cracking. The ET performed consistently

detected previously identified tube imperfections such as cold leg tube thinning,

. tube wear, and manufactured burnish marks at the expected locations, which

indicated an effective inspection.

The inspector observed Rockridge Technologies personnel performing ET data

acquisition for the Unit 2 SG tubes and B&W tube plugs. The inspector verified

that the ET equipment setup parameters, methodology and equipment used were in

accordance with procedure 42-EC-248, "Multifrequency Eddy Current Procedure

Steam Generator Tubing Digital Eddy Current System Prairie Island, Units 1 & 2,"

Revision 2. The ET equipment and techniques used for the tube inspection were

consistent with qualified techniques per Appendix H of EPRI-NP-6201, "EPRI PWR

Steam Generator Ext mination Guidelines," Revision 3. The personnel observed

performing ET data acquisition demonstrated conservative inspection techniques

such as frequently verifying the robot positioning tool at the correct tube location

by using the existing tube plugs as reference points.

The ET data analysis was performed by Rockridge Technologies and Zetec

personnel using Zetec Eddynet95 software. ET data analysis was performed by

prianary and secondary analysts located off-site, with the exception of one primary

data analyst and the resolution analysts located on-site. The on-site analysts

performed ET data analysis in accordance with ISI-ET-1.0, " Bobbin Coil Data

Analysis Guidelines," Revision 7, and with ISI-ET-3.0, " Rotating Coi! Data Analysis

Guidelines," Revision 4. The on-site data analysts demonstrated knowledge of the

latest ET data analysis techniques and made conservative clas6fications of

potential SG tube degradation.

The inspector reviewed Zetec and Rockridge Technologies personnel qualification

and certification records and determined that they met the American Society for

Nondestructive Testing Recommended Practice No. SNT-TC-1 A and ASME Code,

1989 Edition, Section XI requirements. Additionally, the ET data analysts had been

qualified to Appendix G of EPRI-NP-6201, "EPRI PWR Steam Generator Examination

Guidelines," Revision 3. These certifications had been reviewed and accepted by

the Authorized Nuclear Inservice inspector.

The inspector reviewed the ISI procedures used for the ET data acquisition and data

analysis and determined that the procedures met the ASME Code,1989 Edition,

Section XI requirements. These procedures had been reviewed and accepted by the

Authorized Nuclear Inservice Inspector.

c. Conclusions

The inspector observed good preplanning, preparation, and demonstrated

knowledge of the inservice examinations performed, which resulted in ALARA

radiological work practices. Additionally, the inspector identified the following

steam generator inspection staff decisions which demonstrated the licensee staff

focus on safety:

  • The decision to implement the best available technology for inspection of the

B&W mechanical plugs resulted in detecting potentially degraded plugs.

i

During a secondary side pressure test of SG 22 a Westinghouse explosively welded ,

plug installed in 1977 was found to have seepage at the primary tubesheet face. ;

Vendor ABB CE was scheduled to remove and replaced this plug with an inconel !

690 welded plug.

1

The vendor ABB CE removed the remaining Westinghouse mechanical plugs with

heats that had been identified as potentially susceptible to cracking (identified in

NRC Bulletin 89-01 " Failure of Westinghouse Steam Generator Tube Mechanical

Plugs" and NRC informatio'n notice 94-87 " Unanticipated Crack in a Particular Heat

of Alloy 600 Used for Westinghouse Mechanical Flugs for Steam Generator

Tubes"). ABB CE had been tasked by the licensee to replace these 145 plugs with

, inconel 690 rolled plugs. At the conclusion of this inspection, the licensee staff

indicated that they planned to replace the three B&W plugs with circumferentially,

oriented ET indications.

During secondary side pressure testing and visual examination of the SG tubesheet

area, the licensee identified ten tubes in SG-21 and two tubes in SG-22 with

leakage. Each of these tubes had been previously repaired by adding an additional

hard-roll and applying the F* criterion. Only one tube in SG-21 had measurable

, leakage (2 drops per minute) and one tube in SG 22 had measurable leakage (one

'

drop in 3 minutes). The licensee developed an action plan which included:

evaluating previous torque traces and calibration records, conducting profilometry

of selected rerolls, determining the leak rate at main steam line break conditions

with in-situ pressure tests, evaluation of process parameters against the F*

qualification report, and confirming changes in roll transition ET indications after

hydraulic expansion.

On February 5,1997, the Office of Nuclear Reactor Regulation (NRR) staff 1

requested the licensee to resolve NRC staff questions relating to the SG tube ;

leakage implications on the bounding leakage assumed in the qualification reports l

for the F* repair process prior to plant startup. At the conclusion of this inspection ,

on February 13,1997, the licensee staff had met with NRR staff to resolve the I

NRC staff questions.

The licensee staff choose to perform in-situ pressure testing (at main steam line

J

break pressures) to assess the structural and leak tight integrity of the as found 1

condition of 45 F* tubes. The inspector confirmed that this scope included all

leaking tubes which had been identified during the secondary side pressure testing.

At the completion of this inspection the licensee had identified the following

leakage from in-situ pressure testing SG tubes at main steam line break (MSLB)

differential pressure conditions:

SG Tube Location Measured Leak-rate

No. (Row / Column) (Gallons Per Hour)

SG-21 R18C44 0.024

SG-22 R16C38 0.05-0.11 j

SG-22 R13C46 0.00064

The licensee staff determined that the maximum potentialleak rate under MSLB i

differential pressure conditions could have been 0.53 gallons per minute !

contribution from the total population of 288 F* tubes. The licensee staff had j

planned on installing additional rerolls for each of the F' tubes with measurable l

leakage and had scheduled a secondary side pressure test to ensure that these

tubes were not leaking prior to plant startup.

c. Conclusions

The inspector considered that the licensee actions; to perform in-situ pressure

testing of SG tubes for assessment of the as found integrity, to oromptly put in

place a repair plan and address NRC staff questions related to leaking F* SG tubes, ,

to replace tube plugs with heats susceptible to cracking (without identified l

leakage), demonstrated a steam generator repair program focused on safety. I

M4 Maintenance Staff Knowledge and Performance

M4.1 ISI Proaram imolementation

a. Scoce (73051)

The inspector reviewed the inservice inspection data results for the Unit 1 reactor

vessel examination performed in May of 1994 and the Unit 2 reactor ves.sel

examination performed in November of 1993 as part of the ASME Code second

interval inspections.

The inspector reviewed the ISI Summary Reports for the third period second interval

ASME Code examinations for each unit.

The inspector reviewed licensee docketed submittals and participated by phone in a

licensee and NRR staff meeting held on February 6,1996, associated with a

licensee request to use ASME Code Case N-521 " Alternative Rules for Deferral of

inspections of Nozzle-to-Vessel Welds, inside Radius Sections, and Nozzle-to Safe

End Welds of a Pressurized Water Reactor (PWR) Vessel Section XI, Division 1."

The inspector reviewed NRR staff requests for additionalinformation associated

with Code relief requests submitted by the licensee as part of their Third 10-Year

Interval inservice inspection Examination Plan for both Units.

Observations and Findinas

Code Relief Not Obtained for ISI Examinations

Technical Specification 4.2.A.1 requires that the " inservice inspection of ASME

Code Class 1, Class 2, and Class 3 components be performed in accordance with

Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda as

required by 10 CFR 50, Section 50.55(g), except where relief has been granted by

the Commission pursuant to 10 CFR 50.55(g)(6)(i)."

ASME Code, Section XI,1980 Edition Winter 1981 Addenda, lWB-2500(a) requires

" Components shall be examhed and tested as specified in Table IWB-2500-1."

Table IWB-2500-1 requires Volumetric examination of weld volumes defined by

Figure IWB-2500-4 for Category 81.30 welds and volumetric examination of weld

volumes defined by Figures IWB-2500-7(a) through (d) for Category 83.90 welds.

10 CFR 50.55a(g)(5)(iii) requires "If the licensee has determined that a Code

requirement is impractical for its facility, the licensee shall notify the commission

and submit, as specified in 50.4, information to support the determinations."

10 CFR 50.55a(g)(5)(iv) requires "Where an examination requirement by the Code

or addenda is determined to be impractical by the licensee and is not included in the

revised inservice inspection program as permitted by paragraph (g)(4) of this

section, the basis for this determination must be demonstrated to the satisfaction

of the Commission no later than 12 months after the expiration of the initial 120-

8

, l

'

i

1

month period of operation and each subsequent 120-month period of operation

during which the examination is determined to be impractical."

10 CFR 50.55a(g)(6)(i) states "The Commission will evaluate determinations under ;

paragraph (g)(5) of this section that code requirements are impractical. The i

Commission may grant such relief and may impose such alternative requirements as i

it determines is authorized. . . ."

Contrary to these requirements, on February 10,1997, the inspector identified

seven welds in each unit (identified below) for which Code volumetric examination

requirements had not beer, met and for which authorized Code relief had not been

obtained pursuant to 10 CFR 50.55a(g)(6)(i) and Technical Specification 4.2.A.1 ~

requirements. Failure to obtain ASME Code relief is considered a violation (50-

282/97003-01 (a); 50-306/97003-01 (a)) .

l

The inspector reviewed ISI summary reports for Code examinations performed for l

Unit 1 and Unit 2 in the third period of the second interval. In the Unit 1 i

examination report 94-01088L that performed UT of a 31 inch diameter reactor !

coolant system elbow seam weld, a 4 inch wide restraint was listed as a limitation '

preventing a complete Code volumetric examination. No documentation could be

located to indicate the basis for the licensee's determination that the restraint ,

removal was impractical. Thus, the inspector was concerned with 73 Code

examinations, which listed limitations (see third period second interval examinations l

q

listed in Attachment A) that prevented meeting the ASME Section XI Code 4

examination requirements, and for which 10 CFR 50.55a(g)(4) requirements of l

" extent practical" may not have been met. If the licensee had submitted relief

requests as required by 10 CFR 50.55a(g)(5)(iii) there would have been NRC

reviews and authorization of the " extent practical."

ASME Code, Section XI,1980 Edition Winter 1981 Addenda, IWB-2500(a) requires

" Components shall be examined and tested as specified in Table IWB-2500-1,"

IWC-2500(a) requires " Components shall be examined and pressure tested as

specified in Table IWC-2500-1 and IWF-2500 requires " Components supports

subject to examination shall be examined and tested as specified in Table IWF-

2500-1."

Contrary to these requirem'ents on February 12,1997, the inspector identified 73

examinations, affecting both units (identified in attachment A as * limited exam") for

which Code examination requirements had not been met and for which authorized

Code relief had not been obtained pursuant to 10 CFR 50.55a(g)(6)(i) and Technical

Specification 4.2.A.1 requirements. Failure to obtain ASME Code relief for these

examinations is considered an additional example of violation (50-282/97003-

01(b);50-306/97003-01(b)). Based on these findings, the inspector considered that

the extent of this problem was programmatic and many additional examinations

existed which required Code relief.

The licensee staff initially stated that A3ME Code requirements for these

examinations or similar examinations were not required to be met, since they were

examined to the extent practical and limited t,; the design, geometry and/or

materials of construction pursuant to 10 CFR 50.55a(g)(4) requirements. However,

10

,

,

at the completion of this inspection during the final phone exit on February 20,

1997, the licensee staff acknowledged this violation and indicated that Monticello

(applicable Technical Specification is 4.15) was in the same condition. The licensee

did not commit to any actions or schedule to address this situation.

Inadeauate Relief Reauest is Denied

On November 1,1995,.the licensee submitted an ASME Code relief request to use

Code Case 521 relating to ASME Code Section XI examination schedule B

requirements for the deferral of inspections of nozzle-to-vessel welds and inside

radius section examinations for both Units. The following chronology of events

transpired relating to this request:

November 20,1995 NRR assigned the review of this relief request to Idaho

National Engineering Laboratory (INEL).

1

December 13,1995 A conference call was held with NRR, INEL, and the

licensee to request additional information to clarify and

support the basis for this relief request.

July 25,1996 The licensee submitted a historical inspection summary, ,

which referred to Westinghouse Report WCAP-10363,

" Handbook on Flaw Evaluation, Prairie Island 1 and 2

)

Reactor Vessels" for justification.

July 29,1996 INEL requested the licensee to provide WCAP-10363.

1

August 9,1996 The licensee submitted WCAP-10363 and a

'

Westinghouse Report WCAP-10562, " Background and

Technical Basis of Handbook on Flaw Evaluation."

November 6,1996 A conference call was held with NRR, INEL, and the

licensee to clarify the information in the current

submittals.

November 8,1996 A conference call was held with NRR, INEL, and the

l

licensee to discuss the licensee's basis for the relief

'

request and in response the licensee committed to I

revise the relief request.

l

November 26,1996 The licensee submitted further information and revised

the basis for its' proposal to exclude the vessel-to-shell

welds; and enhanced the overall basis for this relief

)

request. ]

l

January 7,1997 A Request for Additional Information (RAl) was issued l

by NRR staff to obtain clarification pertaining to the l

licensee's basis for this relief request. I

.

l

l

11

.

.

February 6,1997 At the licensee's request, a meeting was held at the

NRC headquarters office to discuss RAI questions and

resolve technical questions associated with this relief

request.

February 7,1997 The technicalissues could not be resolved and NRR

staff denied this relief request and gave the licensee the

option to withdraw this request.

A significant amount of NRC staff resources were involved in attempting to review

thi.s poorly prepared and inadequately based relief request. Although subsequent

submittals improved this relief request, ultimately the technical issues could not be

resolved and the licensee opted to withdraw this relief request.

The inspector reviewed the NRR staff requests for additionalinformation associated

with six relief requests submitted by the licensee as part of the Prairie Island Unit 1

Third 10-Year Intervalinservice Inspection Examination Plan. NRR technical staff

issued requests for additionalinformation on four of the six relief requests

submitted by the licensee. Two relief requests required additional technical

justification, one required specific drawings identifying the areas needing relief, and

one should not have been submitted based on an existing NRC endorsed ASME

Code Case, which bounded the issue.

The inspector reviewed the NRR staff requests for additional information associated

with seven relief requests submitted by the licensee as part of the Prairie Island

Unit 2 Third 10-Year Intervalinservice inspection Examination Plan. NRR technical

staff issued requests for additionalinformation on four of the seven relief requests.

Two relief requests required additional technical justification, one required specific

drawings identifying the areas needing relief, and one should not have been

submitted based on an existing NRC endorsed ASME Code Case, which bounded

the issue.

t

c. Conclusions

Because of an inadequately prepared relief request, the NRC staff expended a

significant amount of resources in th9 review of the licensee's relief request to

defer Code mandated examinations associated with the reactor vessel. Although

subsequent submittals improved this relief request, ultimately the technical issues

could not be resolved and the licensee decided to withdraw this relief request. The

inspector identified additional sxamples of relief requests submitted as part of the

licensee's Third 10-Year Interval inservice Inspection Examination Plan, which

lacked detail or an adequate technical basis as originally submitted. The inspector

considered these examples to demonstrate a weakness in the licensee staff's

understanding of the level of detail and technical basis needed to support ASME

Code, Section XI, ISI relief requests.

The inspector identified in excess of 80 examinations which did not meet ASME

Code ISI requirements, without NRC approved Code relief. The inspector

considered this to demonstrate a lack of understanding by the licensee's staff of

regulatory requirements related to Code ISI relief requests.

M8 Miscellaneous Maintenance issues (90712)

!

M8.1 (Closed) LER 282/06011: In this licensee event report, the results of a licensee l

initiated re-review of UT data for Combustion Engineering Tungsten inert Gas l

welded sleeves in Unit 1 SG were identified. The licensee identified three sleeved l

SG tubes returned to service with areas of lack of fusion in the upper sleeve weld l

and three additional tubes with UT data taken outside of the upper sleeve weld

area. Based on review of the licensee safety evaluation #453, Revision one, and j

review of issue tracking report commitments, the inspector considered licensee

l

corrective actions completed to date and/or planned for this issue to be acceptable. l
