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.

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.
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.

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

M4.1 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.

X1 Exit Meeting Summary
At the conclusion of the inspection on February 13,1997, and final phone exit on
February 20,1997, the inspector met with licensee representatives identified herein and
