INC.MILLSTONE POWER STATION UNIT 2 RELIEF REQUEST RR-04-12 FOR THE TEMPORARY NON-CODE COMPLIANT CONDITION OF THE CLASS 3 SERVICE WATER SYSTEM 10 INCH EMERGENCY DIESEL GENERATOR SUPPLY PIPING FLANGE Pursuant to IOCFR50.55a(a)(3)(ii), Dominion Nuclear Connecticut, Inc. (DNC) requests relief from the Section XI requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. This request is based on the hardship of performing required ASME code repair/replacement activities to a piping flange in the 10 inch service water (SW) supply line to the Facility 1 emergency diesel generator (EDG)heat exchangers which has developed a through-wall leak. In accordance with 1OCFR50.55a(g)(1), safety-related piping must meet the requirements applicable to components which are classified as ASME Code Class 3.Options for a code repair include shutting down to replace the piping flange or performing the same repair online. Given the limited risk associated with the present condition, both of these options are considered a hardship without a compensating increase in the level of quality and safety. An alternative of continued operation with compensatory actions is proposed until the flange is replaced at the next refueling outage. Attachment 1 to this letter describes the temporary compensatory actions taken by DNC and the technical basis for the proposed relief request for this 10 inch moderate energy SW flange. A permanent code replacement for the identified 10 inch SW flange will be completed no later than the end of the next refueling outage currently scheduled to start in October 2012.If you have any questions regarding this submittal, please contact Wanda Craft at (804)273-4687.Sincerely,'-.- Q,-'rice -, -Vic esident -Nuclear Engineering O \A01+1 Serial No.11-476 Docket Nos, 50-336 Relief Request RR-04-12 Page 2 of 2 Attachments:

Affected ASME Code Class: Code Class 3

ASME Section XI, IWA-4000

Description:

Repair/Replacement Activities Component:

Service Water (SW) System 10 inch Light Weight Slip-on Flange Material Coated Carbon Steel 2.0 Applicable Code Edition and Addenda Millstone Power Station Unit 2 (MPS2) is currently in the fourth 10-year inservice inspection (ISI) interval, which began on April 1, 2010. American Society of Mechanical Engineers (ASME)Section XI, 2004 Edition, No Addenda (Reference 8.1) applies to the ISI program and is used as the primary ASME code edition for Section XI repair/replacement activities.

The SW system piping design code (code of construction) is ANSI B31.1, 1967 Edition through the summer of 1973 Addendum (Reference 8.4).3.0 Applicable Code Requirement ASME Code Section XI, 2004 Edition, No Addenda, Article IWA-4000, Repair/Replacement Activities.

4.0 Reason

For The Request On August 17, 2011, an operator on rounds observed a yellow salty stain on the floor near the spent fuel pool purification pumps in the auxiliary building (Reference 8.5). There was water and a salt build-up on the I-beam above the stain on the floor. The operator found water dripping at a rate of 10 drops per minute coming from the "A" SW header to the "A" emergency diesel generator (EDG), Water was observed dripping from the outlet side flange on spool SK2952. The leak was confirmed to be on the flange body.

Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 2 of 9 Ultrasonic test (UT) examinations determined the area of degradation on the flange is localized and is currently contained in a radial alignment between two of the twelve flange bolts.Enclosure 1 to this attachment contains UT inspection results for the observed flaw area of the flange.Options for a code repair include shutting down to replace the piping flange or performing the same repair online. Given the limited risk associated with the present condition, both of these options are considered a hardship without a compensating increase in the level of quality and safety. In the case of an online repair, it would require entry into abnormal operating procedures (i.e., OP 2326C, Off-Normal Service Water System Operations) including the following actions and/or conditions to effect a Code repair.1. Ensure that SW temperature is less than 58°F (currently SW-temperature is approximately 71'F and normally remains above 58'F well into October).2. Align vital switchgear room coolers and chillers to the B train (or establish compensatory cooling).3. Disable the A EDG.4. Align the swing reactor building closed cooling water (RBCCW) heat exchanger (HX) to the B train on the SW side and the A train on the RBCCW side and ensure swing RBCCW HX can provide adequate A train cooling with SW flow less than 1500 gpm.5. Align the swing SW pump mechanically to the B train and electrically to the A train and start the pump.6. Align two turbine building component cooling water (TBCCW) HXs to the B train on the SW side (this may require a reactor down power to provide sufficient cooling).Once in this configuration, completion of the work activities for the spool replacement within the remaining time of the limiting condition for operation of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> will not be possible.

Therefore a transition to Mode 5 (a hardship) would be required to perform this repair. Further, there is no compensating increase in plant safety by performing the repair during the operating cycle.

Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 3 of 9 This temporary condition of the leaking 10 inch light weight slip on flange is not in compliance with ASME Section XI, 2004 Edition, IWA-4000, nor does it meet the accepted analysis methods contained in NRC Generic Letter (GL) 90-05 (Reference 8.2). Additionally, Code Case N-513-3 (Reference 8.3) is not applicable for use in structural evaluations because the degradation is in a component (10 inch light weight slip-on flange) which is specifically excluded from the scope of the code case. However, the current pipe stress analysis of record has been reviewed and the pipe stress levels adjacent to the flange (for the non-degraded condition) have been determined to be less than 10% of applicable Code allowables.

The current corrosion damage to the flange is characterized through UT evaluations as limited (contained radially between two of twelve bolt holes). Because the observed damage is limited, it is considered that adequate margin is available to accommodate the corrosion that is anticipated to occur during the remaining 14 months of operation until the next refueling outage.5.0 Proposed Alternative and Basis for Use 5.1 Flaw Characterization

-Based on the UT results of the current condition and experience from other similar lining failures discovered during normal inspection on carbon steel piping components in SW, the flaw is characterized to be a localized area corrosion rather than a crack-like flaw.Dominion procedure ER-AA-NDE-UT-701 (included as Enclosure 2 to Attachment

1) contains additional details on the nondestructive examination process used.The examination process used identified symptoms of localized area corrosion which is consistent with prior experience from other lining failures on this system. The flange in question was not designed to permit a complete volumetric examination once installed.

However, the UT examination process used is capable of identifying localized area corrosion in the flange. There is no history of crack-like flaws in this system and it is not considered credible that such a flaw exists in the small area that did not receive a volumetric examination.

The coating on SW spool SK2952, where the leakage is occurring on the outlet flange, is inspected every other refueling cycle to ensure that the pressure boundary of the SW pipe remains intact and that the tube sheets of safety-related heat exchangers (HXs) do not become clogged by coating material.

This every other refueling outage inspection is based upon the inspection of one train of SW every outage. This inspection scheme has been used for over ten years. Numerous defects have been detected by these inspections and repaired before a through-wall leak occurred.

Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 4 of 9 Galvanic Corrosion Mechanism The typical corrosion encountered in this carbon steel lined pipe, used for MPS2 SW, comes from a break or perforation (holiday) in the coating or lining. This most often is a result of mechanical assembly, disassembly or handling of the spool pieces.The flaws in the coating most often occur in or around the inner diameter (ID) corners of the flanged joints. Once the coating is damaged, seawater gets into the coating and eventually through to the carbon steel. Once the seawater electrolyte makes contact with the carbon steel, galvanic corrosion occurs. The carbon steel is anodic to the surrounding coated carbon steel and any uncoated alloy surfaces.

This creates an electrical current and metal ions are released into solution creating a cavity. The cavity grows from the initial point outwards in a radial shape in all directions and takes on the concave appearance, resembling what could be pictured if the carbon steel was scooped out with an ice cream scoop.As the cavity grows, this electrical current creates a charged electrical field that actually cathodically protects the surrounding area at the sacrifice of the growing anodically charged cavity.When the fit-up line between the slip-on flange ID and pipe outer diameter (OD) is exposed, this narrow space is flooded and exposed to seawater which then becomes subject to corrosion.

However, the geometry of this gap is not favorable for the mass exchange (movement of negatively charged chloride and free oxygen atoms in and positively charged metal ions out) required for rapid corrosion.

The free oxygen within the gap is quickly depleted and the rate of corrosion diminishes to a substantially lower amount compared to that in the active cavity. Thus, significant corrosion of the flange hub or attachment weld beyond the active cavity is not expected.Starting in 2005, sections of the piping have been replaced with super austenitic stainless steel, AL6XN, designed for seawater service. Dominion has planned a programmatic replacement of the safety-related portion of the SW piping. Spool SK2952 is scheduled for replacement in the next refueling outage (fall 2012).The coating on the outlet flange was visually inspected by a qualified linings engineer during 2R19 (October 2009). Lining engineers receive specific training in the inspection of linings to recognize coating defects, The epoxy lining on the flange face and ID of the pipe had no evidence of damage at that time. A typical refueling outage inspection has found 10 to 15 areas where the coating has failed and some corrosion has occurred.

These Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 5 of 9 areas are repaired during the outage. Based upon past experience, more areas of coating damage and corrosion will be found in the next refueling outage, but the chances of another leak are small.It is probable that the lining on the leaking flange was damaged when re-installing the upstream spool. However, a conservative corrosion rate was chosen by assuming the lining defect initiated 11 months ago (one-half the duration since the last inspection occurred) and that the observed damage has occurred in the past 11 months. Based upon UT measurements, the damaged area is about 3 inches long on the ID of the flange (which is approximately 34 inches in circumference and 3/4 inch thick). Past experience has shown that the corrosion from this type of lining defect grows radially from a point on the ID of the flange face. Hence, the 3 inches represents twice the actual growth. Therefore the corrosion rate can be conservatively estimated as 1.5 inches/1I months = 0.136 inches/month.

The extent of the damage to this outlet flange is limited to the one area noted. UT measurements around the circumference of the flange did not identify any similar areas.5.2 Structural Integrity

-Per MPS2 Technical Requirements Manual (TRM)3.4.10, the structural integrity of an ASME component is determined in accordance with either the original construction code or the ASME Section X1 Code, approved code cases or regulatory-approved methods of evaluation.

No NRC approved methodology could be identified (i.e., GL 90-05 and Code Case N-513-3) applicable to flanges. Engineering Technical Evaluation ETE-CME-2011-1005, Revision 0 (Reference 8.5) is a structural integrity assessment of the degraded flange. Pipe stress levels for the Code equations for the adjoining pipe are less than 10% of their associated allowables.

The area of degradation is currently confined to an area radially aligned between two bolt holes on one carbon steel flange. The area of degradation is assumed to be as large as 33% of the flange circumference (or the area between four bolt holes of a twelve bolt hole pattern) for the purpose of the structural integrity assessment.

Based on experience with other similar situations (seawater/exposed carbon steel), this magnitude of corrosion is larger than the magnitude currently predicted by Materials Engineering personnel.

Materials Engineering predicts a radial flaw size of approximately 7 inches at the end of the current operating cycle (i.e., 6.8 inches = 3 inches + 2 x 0.136 inches/month x 14 months, this is approximately 22% of the inside circumference

= 7/(10 x Tr")). Since the limiting case assumes that a 33% maximum wall loss is experienced (to be confirmed periodically by UT) and the adjoining pipe element has 90%margin in the stress equations, stiructural integrity of the flange joint will be maintained for the loading conditions (i.e., dead load, thermal and seismic).The flaw is not crack-like and thus will remain stable under the postulated Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 6 of 9 design loading conditions since a large structural capability margin exists in the worst case degraded flange.5.3 Flow Margin -SW flow loss from this leak location will not adversely affect the capability of the SW system to provide adequate cooling to the EDG HXs and to the other essential safety-related HXs. A leakage limit of 1 gallon per minute (gpm) is applied as the maximum acceptable leakage rate (currently the leakage rate is approximately 10 drops/min).

A detailed system hydraulic analysis has been performed (Reference 8.6). This analysis demonstrates that a margin of at least 50 times is available (i.e., >50 gpm can be tolerated and all essential safety-related HXs receive adequate SW flow for the limiting accident condition).

5.4 Spray

Concerns -A walkdown has been performed by System Engineering.

The walkdown included components within an approximate 30 foot envelope of the current leak. Primary water system components are located within this area including the non-safety related refueling water purification pumps P14A & B, safety related spent fuel pool cooling pumps P13A &B and heat exchangers X20A & B, and'associated piping.Additionally, the non-safety related 480V Motor Control Center.Bus (MCC-B31A) is located approximately 25 feet from the leak. Due to the existing leak location on the flange, the most likely spray direction is toward the concrete building wall at the -5 elevation of the auxiliary building located east of the leak. This wall is approximately 1 foot from the leak location.There are no components between the east wall and the leak location (the most probable spray direction) and no active component within a 15 foot envelope.

The entire inspected area is further protected by a concrete block house on the south side (4 feet from the leak location).

All active components are further protected from spray. due to physical obstructions (walls, piping, hangers, etc.). Based on this review, there are no spray concerns affecting any area components for the worst projected leak.5.5 Flooding -The flooding from an assumed 2 gpm leak (this is two times the action level of I gpm and allows for a leakage rate increase over the 30-day mission time) would result in a total leak volume of approximately 86,400 gallons. This volume is based on a 30-day mission time. The 30-day mission time is based on the GSI-191 containment emergency sump strainer design that has a 30-day mission time. Cooling over the 30-day mission time is provided by SW.As a compensatory measure, leakage will be collected and directed to appropriate drains during normal plant operation, facilitating the ability to Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 7 of 9 monitor for degradation.

These drains may not be available/functional or credited following a design basis accident.If the compensatory drain collection system is unavailable/nonfunctional, then operators will be alerted to any pooling of water. in the auxiliary building basement by existing auxiliary building sump system indication.

A water volume of approximately 120,000 gallons can be accommodated by the auxiliary building basement (Reference 8.7) without impacting safety-related equipment.

Therefore, the flooding for 30 days can be accommodated without operator action.5.6 Extent of Condition

-An on-going capital project has replaced much of the carbon steel lined/coated carbon steel piping. However, many similar coated carbon steel flange joints (to the current leaking joint) remain in service. Recent experience (within the last ten years) with the SW system inspections reveals that through-wall coated component failures are rare.Since the initiator for the current condition is presumed to be damage to the coating system upon reinstallation into the system, no other coated carbon steel component through-wall leaks are expected in the current operating cycle. No other SW system flange leaks are present in the MPS2 SW system. Because the degradation of similar coated carbon steel components has been previously evaluated and is the impetus for the ongoing piping replacement project, no scope expansion to examine additional components is warranted based on the identified degradation of the subject flange. Operators on rounds and system engineering walkdowns will continue to identify future instances of this type in a timely manner, just as this one was discovered.

5.7 Compensatory

Monitoring Plan -Leakage monitoring will be performed.

UT monitoring will be performed on an approximate 30-day interval.

UT examination of the pipe flange, as was done to identify the degraded area, will be done on a monthly basis to track the progression of the corrosion damage. The estimated

-0.150" increase in the damaged area between examinations should be detected.

Monitoring on a more frequent basis would not lend itself to revealing the very small changes which would be expected to occur between frequent examinations and any variability in the measurements may under represent or over represent the actual increase in the damaged area over time. An approximate 30 day interval is adequate and sufficient to detect increases in the damaged area in a timely manner based on the nature of degradation mechanism.

Changes in the area of corrosion will be assessed by Engineering on the presumed corrosion rate and for impact to the structural integrity of the affected flange / flange joint.Leakage rate will be trended by System Engineering on an approximate weekly basis. Operations will qualitatively monitor leakage once per shift. If Serial No.11-476 Docket No. 50-336 Relief Request RR-04-12 Attachment 1, Page 8 of 9 any of the limits outlined within the relief request are challenged (e.g., the leakage rate of 1 gpm or the flaw size (33% of the flange inside circumference)), the A Train SW system will be declared inoperable.

5,8 Conclusion

-Although the structural integrity of the leaking flange cannot be demonstrated in accordance with a regulatory-approved methodology, it is concluded the integrity and functional requirements of the flange will be maintained.

Thus, SW will continue to be capable of providing required cooling water flow to meet the required cooling loads including the EDG HXs. There will be no adverse impact on neighboring equipment due to either spray or flooding.

DNC will implement the compensatory monitoring plan above to ensure any growth of the flaw is identified and assessed for its impact on structural integrity.

6.0 Duration

of Proposed Alternative The affected spool piece was already scheduled to be replaced in October 2012 during 2R21. Therefore, the duration of the proposed alternative is requested until October 2012 or until the limits described above are challenged.

10 DOMINION ER-AA-NDE-UT-701 Revision 5 Page: 5 of 11 1.0 Purpose 1.1 The purpose of this procedure is to provide a process for the calibration and application of straight beam ultrasonic techniques for performing thickness measurements utilizing equipment with A-scan display or direct thickness readout with A-scan displays.2.0 Scope 2.1 This procedure is applicable to the manual, pulse echo, straight-beam, longitudinal wave, contact ultrasonic technique for performing thickness measurements of ferritic or austenitic tubing, piping, vessels, and components in the nominal thickness range of 0.025 to 20.00 inches. Thickness measurements may be taken outside of the specified nominal thickness ranges provided the equipment capabilities is demonstrated through the calibration process and Level III approval is documented on the examination record.2.2 Examinations may be conducted from the inside (ID) or outside (OD) surfaces.2.3 The temperature of the component being examined should not exceed the manufacturer's maximum temperature for the search unit or couplant being used.3.0 Reference Documents 3.1 ASME Boiler & Pressure Vessel Code,Section V, 1989 Edition through the 2004 Edition, Article 23, SE-797, Standard Practice for Measuring Thickness by Manual Ultrasonic Pulse-echo Contact Method.4.0 Personnel Qualifications 4.1 The examiner shall be certified to, Level 11-L (limited to straight beam or thickness measurements), Level II, or Level III in the ultrasonic method in accordance with Dominion's written certification practice.

The examiner shall be responsible for and shall accept the results of the examination.

4.2 An assistant qualified to at least a Level I in the ultrasonic method in accordance with Dominion's written certification practice may assist the examiner.

The Level I shall work under the direct supervision of the examiner and shall not evaluate or accept the examination results.5.0 Equipment and Material Requirements 5.1 All equipment and materials used to implement this procedure shall comply with the requirements of ER-AA-NDE-130, "Storage and Control of Calibrated NDE Equipment, Calibration Standards, and Consumable NDE Materials".

DOMINION ER-AA-NDE-UT-701 Revision 5 Page: 6 of 11 5.2 Ultrasonic Instruments

5.2.1 Approved

pulse echo ultrasonic instruments shall provide either a direct A-scan display or a combination of an A-scan display with direct thickness readout. An acceptable calibration in accordance with this procedure demonstrates acceptable ultrasonic instrument selection for use.5.3 Search Units 5.3.1 Search units with a nominal central frequency in the range of 5.0 to 20.0 MHz should be selected for performing thickness measurements.

For thicknesses 0.050" and less the search unit frequency shall be 10.0 MHz or higher. Other frequencies between 1.0 and 5.0 MHz may be used when their properties (i.e., sensitivity, penetration, resolution, etc.)provide superior results.5.3.2 The search unit active element size should be between 0.10" and 1.00" square inches, however smaller search units may be used provided the resolution capabilities of 5.3.5 are maintained.

5.3.3 The search unit elements shall be round.5.3.4 Either single or dual element search units may be used. Delay lines may be used for high temperature components or when improved near surface resolution is required.5,3.5 Proper search unit selection (size, shape, configuration, frequency) will be indicated by the systems ability to properly display and resolve the calibration standard's reflections throughout the range of the expected thickness measurements for the component to be examined.5.4 Cabling 5.4.1 The interconnecting cable between the search unit and the ultrasonic instrument shall be RG-58 or RG-174 type coaxial cable (or equivalent) with lengths not to exceed 20 feet.5.5 Couplant 5.5.1 A suitable liquid couplant medium shall be applied to the examination surface for the examination.

The couplant shall be approved for use at the site prior to use. The same couplant used for calibration shall be used to perform the examination.

DOMINION ER-AA-NDE-UT-701 Revision 5 Page: 7 of 11 5.6 Reference Blocks 5.6.1 Reference blocks used for screen distance calibration and verification shall be of the same material as the component material being examined (e.g. carbon steel or stainless steel). As an alternative, the component being examined may be used for calibration.

The reference block or component used for calibration must be of known thickness to allow for accurate calibration.

5.7 Thermometer

5.7.1 When required (high temperature components

> 1250 F), a calibrated surface thermometer shall be used to document the surface temperature of the reference block and component prior to the examination.

6.0 Examination

Requirements

6.1 Examination

Area 6.1.1 The extent of the area to be examined and the criteria, by which the ultrasonic measurements and part acceptability will be evaluated, shall be determined by the parties requesting that the examination be performed.

6.2 Surface

Condition Requirements 6.2.1 The examination surface shall be free of irregularities, loose material, or loose coatings which interfere with the ultrasonic wave transmission.

Areas where ultrasonic contact is inadequate shall be documented as limitations.

7.0 Thickness

Measurement Technique I 7.1 Thickness measurements shall be taken using the single echo measurement technique.

7.2 The single echo technique measures the total thickness of the part using a single backwall reflection.

This measurement includes any coating which may be present on the surface, leading to an error in the actual base material thickness, 8.0 Calibration

8.1 Calibration

shall include the complete UT system. Any change in search units, couplant, cables, instruments, or any other part of the system shall be cause for calibration verification.

DOMINION ER-AA-NDE-UT-701 Revision 5 Page: 8 of 11 8.2 The calibration shall be performed with a reference block meeting the requirements of section 5.6.8.3 System setup and calibration (zero, velocity, gain, time base, etc.) shall be performed in accordance with the operating manual for the ultrasonic instrument being used for the examination based upon the selected parameters of the examination (i.e., measurement technique, material, thickness ranges, search units, etc.).8.4 The calibration shall utilize two points of known thickness.

The calibration points may be single backwall reflections or backwall multiples of known thicknesses.

When available, the calibration points should be equal to or greater than the nominal thickness being examined and a thickness less than the nominal thickness being examined.8.5 Upon completion of the system setup and calibration, couple the search unit to each of the thickness steps of the reference block used for calibration and verify that the readings are within +/-0.002 inches of the as-built thickness dimension.

8.6 Calibration

Verification

8.6.1 System

calibration shall be checked using the appropriate reference block. Thickness reading of the calibration points shall be recorded during the initial calibration and shall be verified at the following intervals:.

8.6.1.1 At the start and finish of each examination; 8.6.1.2 With any change in examination personnel; 8.6.1.3 Whenever the instrument has been turned off and then turned on;8.6.1.4 When there is a change in search unit, cable, or couplant;8.6.1.5 At intervals not to exceed four hours;8.6.1.6 Whenever the validity of the calibration is in doubt.8.6.2 If any calibration thickness point changes by more than 0.005 inches, the following shall be performed:

8.6.2.1 Void all examinations referring to the calibration in question and performed after the last valid calibration check;8.6.2.2 Conduct a new calibration; DOMINION ER-AA-NDE-UT-701 Revision 5 Page: 9 of 11 8.6.2.3 Reexamine all areas for which the examinations have been voided, 8.7 For thickness measurements on high temperature components (2: 1250 F) the examination surface shall be within 25' F of the reference block used for calibration.

The thermometer identification and surface temperatures shall be documented on the data sheets.9.0 Examination 9,1 The examination shall be performed using a 100 percent scan, partial scan, or spot check scanning technique.

The type of scan required for each component shall be defined by the parties requesting that the examination be performed.

The types of scans are defined as follows: 9.1.1 100 Percent Scan -This examination will encompass the complete component.

It is a detection, as well as a measuring technique, and should be utilized to detect the thickest and thinnest areas or when encountering inclusions, laminations, or rapidly changing thickness (i.e., erosion/corrosion).

9.1.2 Partial

Scan -This examination covers only a percentage of the component being examined.

The percentage should be based on the requirements of the examination.

This technique should not be utilized if finding the thickest or thinnest area of the component is required.9.1.3 Spot Check -This examination is a point-to-point technique which measures the thickness of the component at predetermined grid locations.

It should not be utilized to detect the thickest or thinnest area of the component being examined.9.2 Thickness readings should be taken using similar couplant thickness and search unit pressure as used for the calibration.

9.3 For dual element search units ensure that the acoustic barrier between the search unit elements is aligned perpendicular to the axis of the pipe to eliminate the effects of the curvature on the UT measurements, 9.4 Thickness readings shall be recorded as required (manually or data logger/recorder).

9.5 The thickness readings taken during an examination should be reviewed at the conclusion of the examination to ensure that no unusual readings exist and that the examination is complete.

If there are any erroneous or missing readings, those areas should be reexamined to ensure accurate examination results.

DOMINION ER-AA-NDE-UT-701 Revision 5 Page: 10 of 11 9.6 Where available, the digital readout should be utilized as the primary source for thickness readings.

The A-Scan display should be monitored to ensure that thickness readings taken are 'true" readings and not the result of couplant readings, inclusions, laminations, etc.9.7 If inclusions or laminations are encountered, the area should be scanned and marked to properly bound the region. The depth(s) of the inclusion(s) or lamination(s) should also be recorded and documented, as necessary.

When areas of laminations are identified, the area of lamination should be examined with a lower frequency search unit to reduce the limited area examined.

Lower frequency search units will often penetrate thin/tight laminations due to the increased penetrating power of the longer wave length.9.8 For components examined through coatings, the coating thickness will cause a slight increase in the recorded thickness from the actual thickness of the component.

Although this increase is small, coating with reported thicknesses near the minimum wall thickness (minimum wall +0.015") should be evaluated to determine if the coating should be removed and the actual thickness verified.9.9 Upon completion of the examination the excess couplant shall be removed.Supplies and equipment shall also be removed from the examination area.10.0 Data Recording 10.1 Calibration and examination data shall be recorded on data sheets and as a minimum shall include the following:

10.1.1 Calibration sheet identification.

10.1.2 Names and certification levels of examination personnel.

10.1.3 Examination procedure number and revision.10.1.4 Reference block identification.

10.1.5 Ultrasonic instrument serial number, manufacturer, and model identification.

10.1.6 Ultrasonic instrument settings.10.1.7 Search unit manufacturer, model, and manufacturer's serial number.10.1.8 Search unit nominal frequency, size, shape, and number of elements.10.1.9 Special search units, wedges, shoe type, or saddle's identification, delay line, if used.10.1.10 Search unit cable type, length, and number of intermediate connectors.

10.1.13 Couplant type and batch number.10.1.14 Identification and location of the component scanned.10.1.15 Surface from which the examination is conducted.

10.1.16 When applicable, the temperature of the reference block and component along with the thermometer manufacturer, model, and serial number.10.1.17 The type of scan completed, i.e. 100 percent scan, partial scan, or spot check. For partial scans, record the approximate percentage of each section examined.10.1.18 Examination results (thickness readings) including limitations of the area scanned. When using data loggers/recorders the data printout may be attached to document the thickness measurements.

10.1.19 A drawing or photograph of the component should be included with the examination records when possible.10.2 All data records shall be reviewed and processed in accordance with ER-AA-NDE-140, "Processing of Dominion NDE Data".

Seismic / nonseismic boundary support seismic loads will be developed in accordance with Reference 4, section 3.13.8.[] Valve accelerations will be determined and evaluated for acceptability.

[] Equipment nozzle loadings/stresses will be determined and evaluated for acceptability.

Z Flange loads will be determined and evaluated for acceptability.

Z Evaluation of pipe local stresses due to Integral Welded Attachments (IWA) will be performed to document acceptability.

The coordinate system for all data expressed in the global system is as follows: (-X) is plant "called North" per piping drawing.(+Y) is vertical "up".(+Z) is accordingto tie right hmnd The local system is defined as follows: For straight piping members (X) is along the axis of the pipe, positive in the direction of coding.(Y) in the plane of the local X-Axis and the global +Y-Axis unless the local X-Axis is aligned withthe global Y-Axis, then the local Y-Axis will be parallel to the global X-Axis.(Z) according to the right hand rule.For curved piping members a radial-normal-tangential system is used where X and Y are in the plane of the curve and Z is normal to the plane as follows: (X) is the tangential component, positive in the direction of coding.(Y) is the positive (outward) radial component.(Z) is normal to the X and Y plane according to the right hand rule.2. Forces and moments on restraints, supports and equipment are those imposed by the piping system (i.e., actions not reactions).

3. Unless otherwise indicated, intersections are considered as unreinforced branch connections.

DEFINITION OF TERMS-.----------

Sc .

w r ~rc -~ tl, 7' , U. litiultutm-ln temp, azure.St, =Allowable stress for Class 2, 3, and Class 4 piping is based on the higher of maximum operating temperature or ambient temperature.

SA = Allowable stress range for expansion stress f(I.25 S, + 0.25 SO).D = Stress due to sustained mechanical loads including deadweight of piping, components, contents and insulation.

E = Stresses due to inertia effects of the OBE.H = Stresses due to occasional loads other than seismic. Examples of these loads would be: water hammer, steam hammer, opening of safety relief valves, etc.T = Stress due to thermal expansion of the system in response to average fluid temperature.

R = Stresses induced in the piping due to thermal growth of equipment and/or structures to which the piping is connected as a result of plant normal or upset conditions.

A =Stresses induced in the piping due to response of the connected equipment and/or structures to the OBE (commonly referred to as OBE anchor movements).

E'= Stresses due to inertia effects of the SSE.Pd = Internal pressure loads due to design pressure.P = Internal pressure loads due to peak pressure.f = Stress range reduction factor for cyclic conditions (See Reference 1, SubSection NC-361 1, for Class 2, ND-361.1 for Class 3 piping).

• Pipe Runs between nodes 7060-7063, 7063-7066 should be in the +X direction to agree with the piping Iso. (Ref. 13.i) instead of-Z direction coded.* Flange weight of 17 lbs at node 2310 was inadvertently input at node 2285. It should be noted that there is already a CWEIGHT card at node 2285.* Flange weights of 26 lbs (Node 1740) and 36 Lbs (Node 1941) were inadvertently omitted in the Nupipe input.7. The Minimum Wall Thickness (t,) calculation shown in Section 5.4 of Revision 3 of this calculation was qualified for a Design Pressure of 100 psig and is included in Attachment D of this calculation.

The calculation sheets included in Attachment D were "marked-up" to show acceptability for a Design Pressure of 150 psig.S. The Design Input (Piping, Pipe Supports, Valves and Heat Exchanger Drawings) from Section 3.1 of Revision 3 of this calculation are included in Attachment D for information only.

Shaw Stone & Webster Nuclear CALCULATION SHEET CALCULATION IDENTIFICATION NUMBER PAGE 15 CALCULATION NO. REV NO CCN NO MP58B-0013SEM 04 NIA 4.0 Methods A. NUPIPE-SWPC Model/ NUDL-PC Computer Program The NUPIPE-SWPC model generated in Revision 4 was developed using the two existing computer models as described below.ADLPIPE Runs (Thermal, Deadweight and Seismic ,inn ly.sis)- 1 M3.00!, 138E.M.006, 138EM3.002, 138EM3:003 as noted"i Section 5.2 6f Revisioin3

&f this calciilaion.

Pipestress run based on CCN 08 to the Revision 3 of this calculation.

This run include Cross-Tie between Service Water lines (8"-JGD-004) above the existing valves 2SW-12B and 2SW-1 2D, and the Fire Protection line 6'"-JBD-026 downstream of valve 2-FIRE-258.

The NUPIPE-SWPC model also incorporated the piping changes based on "CCNs/DCNs" summarized in Revision 3 CCN 01 through CCN 24. The following provides a summary of these modeling updates" DCN DM2-00-0345-08 (Ref. 5a) addresses pipe replacement spool pieces.* DCN's DM2-00-0225-08, DM2-00-0055-08, DM2-01-0054-08 and DM2-00-0054-08 (Ref. 5)which covers replacement of Service Water pipe spool P-14 with AL-6XN material and the removal of Service Water Inlet Strainers L350B, L350A and replacing these components with spool pieces of AL-6XN material." Design Pressure of 150 psi was conservatively considered for the entire stress problem. CCN 10 to Revision 3 of this calculation is qualified for the uprated design pressure of 150 psi to the portions of Service Water to Diesel Engine Coolers. CCN 10 also adds a pair of flanges, a vent and a drain line to Fire Protection line 6"-JBD-26 (analyzed in CCN 08)." Based on CCN 13 to the Revision 3 of this calculation, the overall valve weight for 2-SW-89A1B is changed from 119 lbs to 135 lbs.* Based on CCN 15 to the Revision 3 of this calculation, the overall valve weight for 2-SW-12A/B/C/D is changed from 80 lbs to 292 lbs.Based on CCN 17 to the Revision 3 of this calculation, the overall valve weight for 2-SW-23 lA/B is changed from 156 lbs (noted in CCN 13) to 347 lbs.Service Water line 6"-JGD-7 (between nodes 1870 and 1875) pipe material including fittings and flanges is replaced with material AL-6XN (UNS N08367) per CCN 19 to the Revision 3 of this calculation.

The NUPIPE-SWPC model also addressed the piping replacements being implemented by DCN DM2-00-0345-08 (Ref. 5). Additionally, as described in the correspondence contained on page D9 and D10, Pipe Support 60525 (Nodes 1785, 1825) and 60228 (Nodes 2210, 2250) were modeled as 4-way restraints, and Pipe Support 60221 (Node 2205) and 60523 (Node 1780) were modeled as NS/EW restraints.

The trunnions related to Anchor 60542 (Node 9755 at Floor and Node 9765 at Wall) were also incluided in the NUIPF-.qWPC model--- .: .......................... .. ...... ...-.- 'The NUDL-PC computer program was used to determine the new "Pipe Support Design Loads," B. Operating Conditions The operating conditions considered in the NUPIPE-SWPC analysis were based on Section 5. 1.1 of Revision 3 of this calculation, except a lower 33* F temperature for SW supply piping to the RB CCW heat exchangers was considered instead of 40' F used in the existing analysis, and 1150 F temperature at the outlet of the Diesel Generator Coolers M-7A AND M-7B was also considered.

The specific thermal operating conditions considered in the NUPIPE-SWPC run are summarized in Section 6.5.C. Seismic Response Spectra The applicable Amplified Response Spectra Curves are: Building(s)

Location Elevation Damping Auxiliary Building 14'-6" 0.5% Damping (OBE)(Horizontal Accelerations X and Z Directions)

Vertical Accelerations are 2/3 of the ground acceleration (i.e. 2/3 of 0.O9gs) or 0.06gs for OBE and 0.1 13gs for DBE.SSE Inertia results are obtained by multiplying OBE Inertia results by 1.89 as noted in Section 5.1 of Revision 3 of this calculation and also in Section 3.6 of Pipe Stress Spec SP-M2-ME-030 (Ref. 4), D. Seismic Anchor Movements (SAM's)The Maximum Relative displacements between Auxiliary Building and Warehouse are less than 0.125"and is considered negligible as noted in Section 3.3 of Revision 3 of this calculation.

Therefore SAM's analysis was not performed.

The details extracted from Section 3.3 are documented in Section 6.8 of this calculation.

E. Computer ;Programs The NUPIPE-SWPC program (Ref. 6a) is designed to perform analysis in accordance with the ASME Boiler and Pressure Vessel Cod, Section MI Nuclear Power Plant ('oMrpwenLs.and~als; th S ISA ANSI B3 1.l:0 'PowerPiping Code: This progmpffrisaiiie of tre- " .......dimensional piping systems subjected to various thermal, static and dynamic loading conditions.

The NUDL-PC program (Ref. 6b) is a load combination generator that serves as an aid in the design of pipe support and equipment nozzles. The program reads the pipe support or equipment nozzle loads and global deflections from a file (called CADEPS) created by NUPIPE-SWPC, combine them according to a set of specified combination equations, and outputs to a disk file in a tabular format.The NUPIPE-SWPC and NUDL-PC analyses were performed on a computer system named "1MV7491" which has been designated as a QS 2.7 machine in accordance with Section 11.5.2 of the Shaw Stone& Webster Nuclear Quality Standard Number QS 2,7, Rev. F (Ref. 7).This system is an IBM compatible Personal Computer "DELL" with Pentium 4 CPU, 3.2 GHz with 2.0 GB of RAM, using the Microsoft Windows XP Professional Version 2002, Service Pack 1 Operating System.F. Support 60542 Design Loads Pipe support anchor 60542 is considered to be the "seismic/non-seismic" boundary anchor isolating the non-seismic portion of the piping system from the safety related seismic portion of the piping system.To meet the intent of section 3.2 (item c, seismic/non-seismic boundaries) of Specification SP-M2-ME-030 (Reference 4), the design loads for this support will be determined by "doubling" the existing NUDL-PC based design loads in order to account for the effects of the non seismic piping located beyond the NUPIPE-SWPC analytical model. It should also be noted that two additional supports beyond the seismic/non-seismic anchor 60542 (that are part of the computer model) will be designed considering the seismic loads that were determined by the NUPIPE-SWPC analysis.

The subject flange is located on the Millstone Unit 2 "A" service water supply train to the *A" emergency diesel generator.

This line is designated as 10"JGD-4.

The subject flange is the downstream end of spool piece SK-2952 as shown on Reference 3 isometric drawing.This class 125 light weight flange is lined carbon steel. The degradation Is suspected to be the result of a failed lining which can occur If the coating is compromised during spool installation.

Structural Integrity Assessment:

Currently there is no NRC approved methodology for ASME Code temporary acceptance of flaws in moderate energy Class 3 flanges. ASME Code Case N-513-2 (Reference

4) provides NRC approved flaw acceptance methodology for Class 2 or 3 piping but specifically excludes application to a flange joint.Since no ASME Code or NRC approved methodology is available to evaluate flanges, a non Code methodology is developed here. The objective is to assess the applied piping design loads at the flange (as documented in the stress calculation of record Reference

5) compared to a conservative assessment of the extent of remaining flange material (based on bounding the degradation documented In UT examination report Reference 2). In addition, the piping support local to the flange will be assessed for possible reduction in load carrying capability.

The current piping stress analysis run of record is documented In Addendum B of Reference

5. In the piping analysis computer model the subject flange Is located at node point 580 (shown in model worksketch sheet 3). The ASME Code equation pipe stresses for eq 8, eq 9 normal/upset, eq 9 faulted, eq 10 and eq 11 were extracted (stress calculation Attachment B pages 10 and 53) and are shown in Table 1. Also included in Table 1 are the corresponding allowable stresses and percent ratio of allowable.

As shown in the table the maximum stress at the flange location is 10.0 percent of ASME Code allowable in the undegraded condition.

This low stress condition (1/10 of allowable) provides considerable margin for material degradation while maintaining structural integrity.

The reduced load carrying capability of the flange is proportional to the reduction in area. This results in an increase of 50 percent to the calculated stresses.

This increase in stress will increase the percent ratio of applied to allowable stress from 10 percent to 15 percent leaving 85 percent margin.Node 580 Eq 8 Eq 9N/U Eq 9F Eq 10 Eq 11 Stress (psi)1502 1709 1893 1138 2640 Table 1 Allowable (psi)15000 18000 35000 22500 37500 Percent Ratio of Allowable 10.0 9,49 5.41 5.06 7.04 The UT examination report is included in Attachment B.

-D ominion- Cover Sheet CMAA-T, 0 ATAHMN 2 .. Pae4o showing the through wall leak, located between two bolt holes at the crotch region. The sketch on page B2 identifies the location of the leak relative to the flange orientation.

The bolts/holes have been numbered sequentially 1 through 12 for the purpose of discussion.

As shown in the UT exam report a number of measurements were taken on the flange between each of the twelve bolt holes. Radial and axial thickness measurements were taken on the flange edge, flange face, crotch region and of the pipe at the point of insertion into the flange. Review of this data indicates the degradation Is localized to a single location between two adjacent bolt holes (holes 11 and 12). The adjacent areas and all other areas of the flange do not exhibit any degradation.

This would indicate the current degradation is bounded by an area approximately 116 of the total circumference.

To allow for potential additional flaw growth it can be assumed that 113 of the circumference of the flange has been lost to wastage and only 2/3 of the circumference of the flange remains.Based on the extremely low loads (10 percent of allowable) a 33 percent loss of the flange load bearing area / structural load path will not challenge the structuWal integrity of the flange as the remaining 66 percent flange area is more than sufficient to support the low applied loading.Pipe support mark number 427089 (shown on pipe support isometric drawing Reference

6) is attached to the mating flange.Details of this rigid tandem pipe support are shown on the support detail drawings References 7, 8 and 9. Each leg (attachment point) of this support is rated for a 25001b load per Reference

7. This pipe support utilizes the bolts located in holes 11, 12, 1, 2 on the east side of the support and holes 5 through 8 for the west side of the support. A review of the support load calculation (Attachment E, page 1 of the pipe stress calculation Reference 5, node 580) indicated the maximum load for this support is 17931bs. This load is shared equally between both struts. Therefore each strut is subject to approximately 8971bs (17931bs12).

Strut attachment to the flange is accomplished by4 bolts, through the holes described above. The 25001b capacity of each strut is shared evenly over the 4 attachment bolts. In order to support the required 8971b applied load at least two of the four bolts are required, resulting a reduction of the strut capacity by half to 12501bs. Therefore a minimum of 2 bolts are required at each strut attachment plate. Currently the degraded area is located between bolt numbers 1 and 12 (see sketch Attachment B page B2). Because the flange is degraded in this area It is conservatively assumed bolts 11 and 12 are insufficiently supported to be capable of carrying any load. Bolts 1 and 2 are still capable of carrying load. Since 2 bolts provide adaquate capability for carrying the required load, this support remains fully capably of performing its design function.For the purpose of pipe support qualification, additional flange degradation counter-clockwise In the direction of hole 10 will have no impact on support qualification.

Additional flange degradation in the clockwise direction toward hole 1 is only acceptable provided full flange thickness immediately surrounding hole 1 can continue to be demonstrated (under the nut).Loss of Service Water Flow Assessment:

Service water flow loss from this leak location will not adversely affect the capability 6f the SW system to provide adequate cooling to the EDG heat exchangers and to all other essential safety related heat exchangers.

A leakage limit of 5 gpm is applied as the maximum acceptable leakage rate (currently the leakage rate is approximately 10 drops / min). A detailed system hydraulic analysis has been performed (Attachment A). This analysis demonstrates that a margin of at least 10 to this leak rate is available (i.e., > 50 gpm can be tolerated and all essential safety related heat exchangers receive adequate service water flow for the limiting accident condition.)

Aug 19, 2011 11:29 AM ETE-CME-2011-1005 Report Generated on 8J19/2011 11:29:35 AM Page 5of 65 07D)omninion-Engineering Technical Evaluation Cover Sheet CMA-T-0 .TAHýN 2 ae5o .8.0 Conclusions Based on the above discussion the subject degraded flange maintains structural integrity and remains capable of supporting all required design loads. Since the flange is degraded and exhibiting through wall leakage, it is non compliant with ASME Code requirements.

A conservatively large degradation (1/3 of the circumference of the flange) is considered to allow for potential additional flange degradation.

The associated pipe support (mark number 427089) also remains capable of supporting the required design load. Additional flange degradation is acceptable providing continued demonstration of full flange thickness can be shown under at least 2 of the four nuts supporting each strut attachment plate.9.0 Precautions or Limitations This evaluation places limiltations on the maximum acceptable flange degradation and maximum allowable leak rate. Flange degradation must not exceed 1/3 (120 degrees) of flange circumference and full flange thickness must be maintained under at least 2 of the four nuts supporting each strut attachment plate. Maximum leakage must not exceed 5 gpm. If desired, it is acceptable to impose a more restrictive limitation on maximum leakage to address additional concerns not considered here (such as flooding).

10.0 Required Actions Consistent with the guidance for piping flaw evaluation provided in Reference 4, periodic inspection of approximate 30 day intervals shall be preformed to assure the degraded area remains bounded and the limitations listed in section 9 remain satisfied.

A. CR438193 B. Calculation 92-120 Rev 4 Addendum B, "MP2 SWS Design Basis Alignment-Summer and Winter" dated 3/29/11.C. Calculation 03-ENG-04035M2 "MP2 Service Water Design Basis Summary Calculation" Rev 0 CCN 03 dated 5/24/10 Reference A identified a leak in spool SK-2952 (10-JGD-4).

As requested, a 10 gpm leak and the maximum allowable break as been evaluated using the PROTO-FLO MP2 Service Water flow model documented in Reference B.To verify that the correct model was used, a benchmark case was run. Since Ref B did not run case 2b3 it has been run for the limiting EDG case.Case 2a2 Case 2b3 From Ref B Attach A. Benchmark Benchmark 8/18/1108:41 (Ref B 3/2.8/11 09:08 8/18/11 08:39 did not rerun this case)SW Pump Flow(gpm) 9948.08 9948.08 10946.12 RBCCW Hx Flow (gpm) 8430.25 8430.25 9519.89 DGA Flow(gpm) 774.28 774.28 1721.59 The spool where the break Is located Is modeled In pipe 83. To model the break It can be located at either node encompassing this pipe; either ARBCCW or ADG. Node ARBCCW is located at 3.5 ft elevation and node ADG is located at 11.5 ft elevation.

The break elevation is approximately 9 ft. Cases were run for a 10 gpm break in both locations.

To model the break, the nodal flow in the boundary conditions menu is changed to flow out of the system and a value in gallons per minute is added. For the cases listed in Tables I and 2, 10 gpm was used. To determined the maximum flow, this break size was increased until unacceptable results were obtained.There is less than two-tenths difference between modeling the break at ARBCCW vs ADG. ARCCW is the limiting case for RBCCW and ADG is limiting for the EDG. For the limiting RBCCW case (2a2), the majority of the 10 gpm leak is compensated by increased SW pump flowrate (-6 gpm) to facility 1.RBCCW flow is reduced approximately 3.5 gpm and EDG flow drops approximately 0.3 gpm. For the limiting EDG case (2b3), the leak results in approximately 0.4 gpm reduction in flow. The normal Page 1 of 3 Attachment

These runs conservatively assume the EDG bypass is open.The limiting case for RBCCW (Case 2a2 with the leak at node ARBCCW) and the EDG (Case 2b3 with leak at node ADG) were run to determine the maximum break size that still provides the minimum flow requirements.

This maximum break size was determined to be 54 gpm.! t 4 T t T A .I tq W. d A q 4 Table 1: LUOA wlo LNP Summer Uperation
