CRYSTAL RIVER UNIT 3 DOCKET NUMBER 50-302 / LICENSE NUMBER DPR-72 LICENSE AMENDMENT REQUEST #264, REVISION 2 Application to Modify Improved Technical Specifications Regarding Steam Generator Tube Integrity ATTACHMENT A Request for Additional Information Response

U.S. Nuclear Regulatory Commission Attachment A 3F0307-07 Page 1 of 5 Request for Additional Information Response On February 23, 2007, the Nuclear Regulatory Commission (NRC) issued a Request for Additional Information (RAI, Reference 3) concerning Revision 1 of License Amendment Request (LAR) #264 to modify the Crystal River Unit 3 (CR-3) Improved Technical Specifications (ITS) regarding steam generator tube integrity (Reference 1).

Florida Power Corporation (FPC), doing business as Progress Energy Florida, Inc., hereby provides the following response to this RAI. Since these responses involved changing some of the proposed text in Attachments C through F, this reply to the RAI constitutes Revision 2 to LAR #264, and replaces Revision 1, submitted December 21, 2006, in its entirety.

NRC Request

1. In your response to Question 8, you indicated that the second sentence of TS 5.6.2.10.4.a.1l.b was deleted since it refers to inspection categories that were deleted.

Although the inspection categories were deleted, this sentence contained expansion criteria for your inspection that were not captured in your proposal. Please discuss your plans to incorporate this expansion criteria into your proposed TSs (without reference to the inspection categories).

In addition, with respect to proposed TS 5.6.2.10.d.8, please discuss your plans to replace "degradation of a repair roll" with "flaw or flaws in a repair roll" since TSTF replaced the term "degradation" with the term "flaws."

Florida Power Corporation (FPC) Response

1. In LAR #264, Revision 1, CR-3 ITS 5.6.2.10.4.a.11.b (discussed in the question above) was moved to ITS 5.6.2.10.d.8. FPC agrees that when the inspection categories were deleted, a sentence requiring the examination of both Once Through Steam Generators (OTSGs) under certain circumstances was also deleted. FPC also agrees that this expansion criterion should be retained in ITS 5.6.2.10.d.8 even though the inspection category is being deleted.

To reflect this, the text for ITS 5.6.2.10.d.8 in Attachments C and D has been changed to require both OTSGs to be examined when a repair roll flaw(s) is the cause of a plant shutdown. This is now consistent with current requirements. FPC also agrees to replace the term "degradation of" in ITS 5.6.2.10.d.8 with "a flaw in" which is equivalent to the term, "a flaw or flaws in." The requested revision to Paragraph 5.6.2.10.d.8 has been changed to read as follows (the line-outs indicate deleted text and the bold text indicates added text):

"If the plant is required to shut down due to primary-to-secondary leakage and the cause is determined to be o

-ef a flaw in a repair roll, 100% of the repair rolls in AW both OTSGs shall be examined."

FPC feels this text revision remains technically consistent with TSTF-449, Revision 4, and therefore it does not change the description or the assessment presented in Attachment B to this amendment request.

U.S. Nuclear Regulatory Commission Attachment A 3F0307-07 Page 2 of 5 NRC Request

2. In your response to Question 1, you indicated that you would remove the exception to the accident-induced-leakage performance criterion.

Please discuss your plans to remove similar text from your Bases (refer to page B 3.4-78).

FPC Response

2. FPC agrees it is appropriate to remove the exception to the accident induced leakage performance criterion in the Bases on page B 3.4-78. The requested revision to the third paragraph on page B 3.4-78 in Attachments E and F has been changed to read as follows:

"The accident induced leakage performance criterion ensures that the primary to secondary LEAKAGE caused by a design basis accident, other than a SGTR, is within the accident analysis assumptions. The accident analysis assumes that accident

-induced leakage does not exceed one gallon per minute per OTSG, except for specific "yes of degradation at specofi locations where the NRC hasaproe greater accident ind.ed leak-age. The accident induced leakage rate includes any primary to secondary LEAKAGE existing prior to the accident in addition to primary to secondary LEAKAGE induced during the accident."

FPC feels this text revision remains technically consistent with TSTF-449, Revision 4, and therefore it does not change the description or the assessment presented in Attachment B to this amendment request.

NRC Request

3. In your response to Question 8, you indicated that an additional sentence was added to clarify the repair criteria for intergranular attack (IGA). In reviewing the proposed text, it does not appear to address the repair criteria for all IGA indications in the first span of Steam Generator B. For example, it only addresses the acceptance criteria for those indications in the Inservice Inspection Surveillance Procedure (and there is no requirement to record the indications in this document). In addition, it does not specify the actions to take when these indications satisfy the repair criteria (i.e., the tubes must be plugged or repaired). Please discuss your plans to clarify the repair criteria for all first span IGA indications. The staff notes that the proposed repair criteria appear identical to the standard 40-percent depth based tube repair criteria and could possibly be deleted.

FPC Response

3. Text has been added to ITS 5.6.2.10.c.1 to reflect that action must be taken when indications satisfy the repair criterion. Also, reference made to the OTSG Inservice Inspection Surveillance Procedure has been removed since there is no requirement to record the indications in this document. Similar text exists in the first paragraph of ITS 5.6.2.1O.d.4, so deletion of the same reference in this section will be made, as well. Based on the above, the requested revision to ITS 5.6.2.1O.c.1 in Attachments C and D has changed to read as follows (the line-outs indicate deleted text and the bold text indicates added text):

U.S. Nuclear Regulatory Commission Attachment A 3F0307-07 Page 3 of 5 "Pit-like Intergranular Attack (IGA) indication means a bobbin coil indication confirmed by Motorized Rotating Pancake Coil (MRPC) or other qualified inspection techniques to have a volumetric, pit-like morphology characteristic of IGA. Inservice tubes with pit-like IGA indications in the first span of the B OTSG, idenf*Wed inh*teo OSG.isei..ee Inspe.ti. n Ste.

l e Pro..

dure are acceptable to rema... n in seriee provided the depth of the indication is less than 40% of the nominal tube wall thickness. Inservice tubes with pit-like IGA indications in the first span of the B OTSG with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged."

Similarly, the first paragraph of ITS 5.6.2.1O.d.4 in Attachments C and D has been changed to read as follows:

"Inservice tubes with pit-like IGA indications in the first span of the B OTSGr identified in the OTSG I.se...iee In.pection Surveillance Pr.ed.re must be inspected with bobbin and Motorized Rotating Pancake Coil (MRPC) eddy current techniques from the lower tube sheet secondary face to the bottom of the first tube support plate during each inservice inspection of the B OTSG."

FPC feels this text revision remains technically consistent with TSTF-449, Revision 4, and therefore it does not change the description or the assessment presented in Attachment B to this amendment request.

NRC Request

4. The proposed structure for TS 5.6.2.10.c could result in misinterpreting the requirements since the first sentence indicates that alternate repair criteria are discussed below and the next sentence is not an alternate tube repair criteria. Please discuss your plans to clarify the requirements.

Clarity could be achieved by: (1) numbering the first sentence (as number 1) and replacing "below" with "in Technical Specification 5.6.2.10.c.3"; (2) number the second sentence (as number 2); (3) numbering the third clause (as number 3) and adding "in Technical Specification 5.6.2.10.c.a" at the end of the clause; and (4) renumbering "1" and "2" as "a" and "b."

FPC Response

4. To address this concern, text in ITS 5.6.2.10.c was restructured, but not as described above.

The second paragraph (starting with "Tubes shall be plugged..." and ending with

"...sleeve/tube assembly. ") was moved to the first paragraph after the first sentence of that paragraph. The remaining of what had been the first paragraph (the text starting with "The non-sleeved region of a tube..." and ending with "...an alternate tube repair criteria discussed below. ") has become the second paragraph. No text has been added or deleted.

Reflecting the changes described above, the requested revision to ITS 5.6.2.10.c in Attachments C and D has been changed to read as follows:

"Provisions for OTSG tube repair criteria. Tubes shall be plugged if the sleeved region of a tube is found by inservice inspection to contain flaws in the (a) sleeve or (b) the pressure boundary portion of the original tube wall in the sleeve/tube assembly.

U.S. Nuclear Regulatory Commission Attachment A 3F0307-07 Page 4 of 5 "The non-sleeved region of a tube found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged or repaired except if the flaws are permitted to remain in service through application of an alternate tube repair criteria discussed below.

"The following alternate tube repair criteria may be applied as an alternative to the 40% depth based criteria..."

FPC feels this text revision remains technically unchanged and consistent with TSTF-449, Revision 4. Therefore, this revision does not change the description or the assessment presented in Attachment B to this amendment request.

NRC Request

5. In the second sentence of proposed TS 5.6.2.10.c.2, it would appear that the sentence should read, "provided the combined projected leakage from all sources of primary to secondary leakage." Please discuss your plans to clarify this requirement.

FPC Response

5. ITS 5.6.2.10.c.2 in Attachments C and D has been changed to include the words "sources of" in the second sentence of the first paragraph. The revised sentence now reads as follows:

"Tubes with axially oriented TEC may be left in-service using the method described in Topical Report BAW-2346P, Revision 0, provided the combined projected leakage from all sources of primary-to-secondary leakage, including axial TEC indications left in-service, does not exceed the Main Steam Line Break (MSLB) accident leakage limit of one gallon per minute, minus 150 gallons per day, per OTSG. "

FPC feels this text revision remains technically unchanged and consistent with TSTF-449, Revision 4.

Therefore, this revision does not change the description or the assessment presented in Attachment B to this amendment request.

NRC Request

6. In the first sentence of the second paragraph of proposed TS 5.6.2.10.c.2, you indicate that tubes identified with tube end cracking that meet the alternate repair criteria will be added to the existing list of tubes in the surveillance procedure. In TSTF-449, the phrase "satisfy the tube repair criteria" is used to indicate that an indication exceeds the tube repair criteria (i.e., the tube must be plugged or repaired). However, in the sentence in TS 5.6.2.10.c.2, the phrase "meet the alternate repair criteria" is used to indicate that if a tube is allowed to remain in service (i.e., it does not exceed the alternate repair criteria), then-it should be added to the list of tubes in the surveillance procedure. To ensure consistent terminology throughout this specification, discuss your plans to clarify TS 5.6.2.10.c.2 by indicating that tubes identified with tube end cracking that are allowed to remain in service under the alternate repair criteria will be added to the list.

U.S. Nuclear Regulatory Commission Attachment A 3F0307-07 Page 5 of 5 FPC Response

6. FPC agrees that text should be added to ITS 5.6.2.10.c.2 to clarify that the subject tubes do not just meet the alternate repair criteria, but have been allowed to remain in service under that criteria. The first sentence in the second paragraph of ITS 5.6.2.10.c.2 in Attachments C and D has been changed to read as follows (the line-out indicates deleted text and the bold text indicates added text):

"Tubes identified with TEC that meet are allowed to remain in service under the alternate repair criteria will be added to the existing list of tubes in the OTSG Inservice Inspection Surveillance Procedure."

FPC feels this text revision remains technically unchanged and consistent with TSTF-449, Revision 4. Therefore, this revision does not change the description or the assessment presented in Attachment B to this amendment request.

Program A Steam Generator Program shall be established and implemented td ensure that OTSG tube integrity is maintained.

In addition, the'

,Steam Generator Program shall include the following provisions:

a._ 1Provisions for condition monitoring assessments.

Condition monitoring assessment means an evaluation of the "as found" condition of the tubing with respect to the performance criteria for structural integrity and accident induced-Ileakage.

The "as found" condition refers to the condition of the tubing during an OTSG inspection outage, as,

'determined from the inservice inspection results or by other means, prior to the plugging or repair of tubes.

Condition monitoring assessments shall be conducted during each outag-during which the OTSG tubes are inspected, plugged, orL repaired to confirm that the performance criteria are being met.

b. Performance criteria for OTSG tube integrity.

OTSG tub integrity shall be maintained by meeting the performance criteria for tube structural integrity, accident induced leakage, and operational LEAKAGE.I---

11.

Structural integrity performance criterion:

All in-iservice steam generator tubes shall retain structural integrity over the full range of normal operating conditions (including startup, operation in the power, range, hot standby, and cool down and all anticipated transients included in the design specification) and design basis accidents.

This includes retaining aF safety factor of 3.0 against burst under normal steadyL state full power operation primary-to-secondary pressure differential and a safety factor of 1.4 against burstF applied to the design basis accident primary-to---.-

secondary pressure differentials.

Apart from the b-a-e Srequirements, additional loading conditions associated with the design basis accidents, or combination of

,accidents in accordance with the design and licensing' basis, shall also be evaluated to determine if the -

associated loads contribute significantly to burst orI collapse.

In the assessment of tube integrity, those, loads that do significantly affect burst or collapse' shall be determined and assessed in combination with thý loads due to pressure with a safety factor of 1.2 on the' combined primary loads and 1.0 on axial secondary loads.

Program A Steam Generator Program shall be established and implemented to ensure that OTSG tube integrity is maintained.

In addition, the Steam Generator Program shall include the following provisions:

a.

Provisions for condition monitoring assessments.

Condition monitoring assessment means an evaluation of the "as found" condition of the tubing with respect to the performance criteria for structural integrity and accident induced leakage.

The "as found" condition refers to the condition of the tubing during an OTSG inspection outage, as determined from the inservice inspection results or by other means, prior to the plugging or repair of tubes.

Condition monitoring assessments shall be conducted during each outage during which the OTSG tubes are inspected, plugged, or repaired to confirm that the performance criteria are being met.

b.

Performance criteria for OTSG tube integrity.

OTSG tube integrity shall be maintained by meeting the performance criteria for tube structural integrity, accident induced leakage, and operational LEAKAGE.

1.

Structural integrity performance criterion:

All in-service steam generator tubes shall retain structural integrity over the full range of normal operating conditions (including startup, operation in the power range, hot standby, and cool down and all anticipated transients included in the design specification) and design basis accidents.

This includes retaining a safety factor of 3.0 against burst under normal steady state full power operation primary-to-secondary pressure differential and a safety factor of 1.4 against burst applied to the design basis accident primary-to-secondary pressure differentials.

Apart from the above requirements, additional loading conditions associated with the design basis accidents, or combination of accidents in accordance with the design and licensing basis, shall also be evaluated to determine if the associated loads contribute significantly to burst or collapse.

In the assessment of tube integrity, those loads that do significantly affect burst or collapse shall be determined and assessed in combination with the loads due to pressure with a safety factor of 1.2 on the combined primary loads and 1.0 on axial secondary loads.

2.

Accident induced leakage performance criterion: The primary to secondary accident induced leakage rate for any design basis accident, other than an OTSG tube rupture, shall not exceed the leakage rate assumed in the accident analysis in terms of total leakage rate for all OTSGs and leakage rate for an individual OTSG.

Leakage is not to exceed one gallon per minute per OTSG.

3.

The operational LEAKAGE performance criterion is specified in LCO 3.4.12, "RCS Operational LEAKAGE."

c.

Provisions for OTSG tube repair criteria.

Tubes shall be plugged if the sleeved region of a tube is found by inservice inspection to contain flaws in the (a) sleeve or (b) the pressure boundary portion of the original tube wall in the sleeve/tube assembly.

The non-sleeved region of a tube found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged or repaired except if the flaws are permitted to remain in service through application of an alternate tube repair criteria discussed below.

The following alternate tube repair criteria may be applied as an alternative to the 40% depth based criteria:

1.

Pit-like Intergranular Attack (IGA) indication means a bobbin coil indication confirmed by Motorized Rotating Pancake Coil (MRPC) or other qualified inspection techniques to have a volumetric, pit-like morphology characteristic of IGA.

Inservice tubes with pit-like IGA indications in the first span of the B OTSG are acceptable provided the depth of the indication is less than 40% of the nominal tube wall thickness.

Inservice tubes with pit-like IGA indications in the first span of the B OTSG with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged.

Tube End Cracks (TEC) are those crack-like eddy current indications, circumferentially and/or axially oriented, that are within the Inconel clad region of the primary face of the upper and lower tubesheets, but do not extend into the carbon steel-to Inconel clad interface.

Tubes with axially oriented TEC may be left in-service using the method described in Topical Report BAW-2346P, Revision 0, provided the combined projected leakage from all sources of primary-to-secondary leakage, including axial TEC indications left in-service, does not exceed the Main Steam Line Break (MSLB) accident leakage limit of one gallon per minute, minus 150 gallons per day, per OTSG.

The contribution to MSLB leakage rates from TEC indications shall be determined utilizing the methodology in Addendum B dated August 10, 2005 to Topical Report BAW-2346P, Revision 0. The projection of TEC leakage that may develop during the next operating cycle shall be determined using the methodology in Addendum C dated August 30, 2005 to Topical Report BAW-2346P, Revision 0.

Tubes identified with TEC that are allowed to remain in service under the alternate repair criteria will be added to the existing list of tubes in the OTSG Inservice Inspection Surveillance Procedure.

The inspection data for tubes with axially oriented TEC indications shall be compared to the previous inspection data to monitor the indications for growth.

Tubes with crack-like indications within the carbon steel portion of the tubesheet, circumferentially oriented TEC, or volumetric indications within the Inconel clad region of the tubesheet shall be repaired using the appropriate method from 5.6.2.10.f or removed from service by plugging the tube.

Provisions for OTSG tube inspections.

Periodic OTSG tube inspections shall be performed.

The number and portions of the tubes inspected and methods of inspection shall be performed with the objective of detecting flaws of any type (e.g., volumetric flaws, axial and circumferential cracks) that may be present along the length of the tube, from the tube-to-tubesheet weld at the tube inlet to the tube-to-tubesheet weld at the tube outlet, and that may satisfy the applicable tube repair criteria.

The tube-to-tubesheet weld is not part of the tube.

In tubes repaired by sleeving, the portion of the original tube wall between the sleeve's joints is not an area requiring re-inspection.

In addition to meeting the requirements of d.1 through d.8 below, the inspection scope, inspection methods, and inspection intervals shall be such as to ensure that OTSG tube integrity is maintained until the next OTSG inspection.

An assessment of degradation shall be performed to determine the type and location of flaws to which the tubes may be susceptible and, based on this assessment, to determine which inspection methods need to be employed and at what locations.

1.

Inspect 100% of the tubes in each OTSG during the first refueling outage following OTSG replacement.

2.

Inspect 100% of the tubes at sequential periods of 60 effective full power months.

The first sequential period shall be considered to begin after the first inservice inspection of the OTSGs.

No OTSG shall operate for more than 24 effective full power months or one refueling outage (whichever is less) without being inspected.

3.

If crack indications are found in any OTSG tube, then the next inspection for each OTSG for the degradation mechanism that caused the crack indication shall not exceed 24 effective full power months or one refueling outage (whichever is less).

If definitive information, such as from examination of a pulled tube, diagnostic non-destructive testing, or engineering evaluation indicates that a crack-like indication is not associated with a crack(s), then the indication need not be treated as a crack.

Inservice tubes with pit-like IGA indications in the "B" OTSG first span shall be monitored for growth of these indications by using a test probe equivalent to the high frequency bobbin probe used in the 1997 inspection.

The indicated percentage through-wall value from the current inspection shall be compared to the indicated percentage through-wall value from the 1997 inspection.

5.

Tubes in-service with axially oriented tube end cracks (TEC) are identified in the OTSG Inservice Inspection Surveillance Procedure.

The portion of the tube with the axial TEC must be inspected using the motorized rotating coil eddy current technique every 24 effective full power months or one refueling outage, whichever is less.

6.

If the plant is required to shut down due to primary-to-secondary leakage and the cause is determined to be degradation of the TEC portion of the tubes, 100% of the tubes with TEC in that OTSG shall be examined in the location of the TEC.

If more than 1% of the examined tubes satisfy the tube repair criteria, 100% of the tubes with TEC in the other OTSG shall be examined in the location of the TEC.

7.

The repair roll in each tube will be inspected every 24 effective full power months or one refueling outage (whichever is less) while the tube with a repair roll is in service.

RCS Operational LEAKAGE B 3.4.12 B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.12 RCS Operational LEAKAGE BASES BACKGROUND During the life of the plant, the joint and valve interfaces contained in the RCS can produce varying amounts of reactor coolant LEAKAGE, through either normal operational wear or mechanical deterioration.

The purpose of the RCS Operational LEAKAGE LCO is to limit system operation in the presence of LEAKAGE from these sources to amounts that do not compromise safety.

This LCO specifies the types and amounts of LEAKAGE.

10 CFR 50, Appendix A, GDC 30 (Ref.

1),

requires means for detecting and, to the extent practical, identifying the source of reactor coolant LEAKAGE.

Regulatory Guide 1.45 (Ref. 2) describes acceptable methods for selecting leakage detection systems.

OPERABILITY of the leakage detection systems is addressed in LCO 3.4.14, "RCS Leakage Detection Instrumentation."

The safety significance of RCS LEAKAGE varies widely depending on its source, rate, and duration.

Therefore, detecting, monitoring, and quantifying reactor coolant LEAKAGE is critical.

Quickly separating the identified LEAKAGE from the unidentified LEAKAGE is necessary to provide quantitative information to the operators, allowing them to take corrective action should a leak occur.

A limited amount of leakage inside containment is expected from auxiliary systems that cannot be made 100% leaktight.

Leakage from these systems should be detected, located, and isolated from the containment atmosphere, if possible, to not interfere with RCS leakage detection.

APPLICABLE SAFETY ANALYSES Except for primary to secondary LEAKAGE, the safety analyses do not address operational LEAKAGE.

However, other operational LEAKAGE is related to the safety analyses for a LOCA in that the amount of leakage can affect the probability of such an event.

The safety analysis for an event resulting in steam discharge to the atmosphere assumes 1: gpI primary to seeondary LEAKAGE as the initial ondition.

RCS Operational LEAKAGE B 3.4.12 BASES APPLICABLE that primary to secondary LEAKAGE from all steam generators]

SAFETY ANALYSES (OTSGs) is one gallon per minute or increases to one gallon (continued) per minute as a result of accident induced conditions.

The ILCO requirement to limit primary to secondary LEAKAGE, through any one OTSG to less than or equal to 150 gall6oins per day is significantly less than the conditions assumed in the safety analysis.l The FSAR (Ref.

3) analysis for steam generator tube rupture (SGTR) assumes the contaminated secondary fluid is only briefly released via safety valves and the majority is steamed to the condenser.

The 1 gpm primary to secondary LEAKAGE sfet-ynalysis assumption is relatively inconsequential in terms of offsite dose.

The safety analysis for the Steam Line Break (SLB) accident assumes the enti-r 1 gpm primary to secondary LEAKAGE +n one [is through the affected generator as an initial condition (Ref.

4).

The dose consequences resulting from the SLB accident meet the acceptance criteria defined in 10 CFR 50.67.

RCS operational LEAKAGE satisfies Criterion 2 of the NRC Policy Statement.

LCO RCS operational LEAKAGE shall be limited to:

a.

Pressure Boundary LEAKAGE No pressure boundary LEAKAGE is allowed, being indicative of material deterioration.

LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE.

Violation of this LCO could result in continued degradation of the reactor coolant pressure boundary (RCPB).

LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.

b.

Unidentified LEAKAGE One gallon per minute (gpm) of unidentified LEAKAGE is allowed as a reasonable minimum detectable amount that the containment atmosphere and sump level monitoring equipment can detect within a reasonable time period.

Violation of this LCO could result in continued degradation of the RCPB, if the LEAKAGE is from the pressure boundary.

This action reduces the LEAKAGE and also reduces the stresses that tend to degrade the pressure boundary.

The Completion Times allowed are reasonable, based on operating experience, to reach the required conditions from full power conditions in an orderly manner and without challenging plant systems.

In MODE 5, the pressure stresses acting on the RCPB are much lower and further deterioration is much less likely.

Pressure boundary LEAKAGE would at first appear as unidentified LEAKAGE and can only be positively identified by inspection.

RCS Operational LEAKAGE B 3.4.12 B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.12 RCS Operational LEAKAGE BASES BACKGROUND During the life of the plant, the joint and valve interfaces contained in the RCS can produce varying amounts of reactor coolant LEAKAGE, through either normal operational wear or mechanical deterioration.

The purpose of the RCS Operational LEAKAGE LCO is to limit system operation in the presence of LEAKAGE from these sources to amounts that do not compromise safety.

This LCO specifies the types and amounts of LEAKAGE.

10 CFR 50, Appendix A, GDC 30 (Ref.

1), requires means for detecting and, to the extent practical, identifying the source of reactor coolant LEAKAGE.

Regulatory Guide 1.45 (Ref.

2) describes acceptable methods for selecting leakage detection systems.

OPERABILITY of the leakage detection systems is addressed in LCO 3.4.14, "RCS Leakage Detection Instrumentation."

The safety significance of RCS LEAKAGE varies widely depending on its source, rate, and duration.

Therefore, detecting, monitoring, and quantifying reactor coolant LEAKAGE is critical.

Quickly separating the identified LEAKAGE from the unidentified LEAKAGE is necessary to provide quantitative information to the operators, allowing them to take corrective action should a leak occur.

A limited amount of leakage inside containment is expected from auxiliary systems that cannot be made 100% leaktight.

Leakage from these systems should be detected, located, and isolated from the containment atmosphere, if possible, to not interfere with RCS leakage detection.

APPLICABLE SAFETY ANALYSES Except for primary to secondary LEAKAGE, the safety analyses do not address operational LEAKAGE.

However, other operational LEAKAGE is related to the safety analyses for a LOCA in that the amount of leakage can affect the probability of such an event.

The safety analysis for an event resulting in steam discharge to the atmosphere assumes (conti nued)

Crystal River Unit 3 B 3.4-53 Revision No.

RCS Operational LEAKAGE B 3.4.12 BASES APPLICABLE that primary to secondary LEAKAGE from all steam generators SAFETY ANALYSES (OTSGs) is one gallon per minute or increases to one gallon (continued) per minute as a result of accident induced conditions.

The LCO requirement to limit primary to secondary LEAKAGE through any one OTSG to less than or equal to 150 gallons per day is significantly less than the conditions assumed in the safety analysis.

The FSAR (Ref.

3) analysis for steam generator tube rupture (SGTR) assumes the contaminated secondary fluid is only briefly released via safety valves and the majority is steamed to the condenser.

The 1 gpm primary to secondary LEAKAGE safety analysis assumption is relatively inconsequential in terms of offsite dose.

The safety analysis for the Steam Line Break (SLB) accident assumes the entire 1 gpm primary to secondary LEAKAGE is through the affected generator as an initial condition (Ref.

4).

The dose consequences resulting from the SLB accident meet the acceptance criteria defined in 10 CFR 50.67.

RCS operational LEAKAGE satisfies Criterion 2 of the NRC Policy Statement.

LCO RCS operational LEAKAGE shall be limited to:

a.

Pressure Boundary LEAKAGE No pressure boundary LEAKAGE is allowed, being indicative of material deterioration.

LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE.

Violation of this LCO could result in continued degradation of the reactor coolant pressure boundary (RCPB).

LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.

b.

Unidentified LEAKAGE One gallon per minute (gpm) of unidentified LEAKAGE is allowed as a reasonable minimum detectable amount that the containment atmosphere and sump level monitoring equipment can detect within a reasonable time period.

Violation of this LCO could result in continued degradation of the RCPB, if the LEAKAGE is from the pressure boundary.

(continued)

Crystal River Unit 3 B 3.4-54 Revision No.

RCS Operational LEAKAGE B 3.4.12 BASES LCO

c.

Identified LEAKAGE (conti nued)

Up to 10 gpm of identified LEAKAGE is considered allowable because LEAKAGE is from known sources that do not interfere with the detection of unidentified LEAKAGE and is well within the capability of the RCS makeup system.

Identified LEAKAGE includes LEAKAGE to the containment from specifically known and located sources, but does not include pressure boundary LEAKAGE or controlled reactor coolant pump (RCP) seal leakoff (a normal function not considered LEAKAGE).

Violation of this LCO could result in continued degradation of a component or system.

d.

Primary to Secondary LEAKAGE through Any One OTSG The limit of 150 gallons per day per OTSG is based on the operational LEAKAGE performance criterion in NEI 97-06, Steam Generator Program Guidelines (Ref.

5).

The Steam Generator Program operational LEAKAGE performance criterion in NEI 97-06 states, "The RCS operational primary to secondary leakage through any one SG shall be limited to 150 gallons per day."

The limit is based on operating experience with OTSG tube degradation mechanisms that result in tube leakage.

The operational leakage rate criterion in conjunction with the implementation of the Steam Generator Program is an effective measure for minimizing the frequency of steam generator tube ruptures.

Crystal River Unit 3 B 3.4-55 Revision No.

RCS Operational LEAKAGE B 3.4.12 BASES ACTIONS A.1 If unidentified LEAKAGE or identified LEAKAGE is in excess of the LCO limits, the LEAKAGE must be reduced to within limits within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

This Completion Time allows time to verify leakage rates and either identify unidentified LEAKAGE or reduce LEAKAGE to within limits before the reactor must be shut down.

This action is necessary to prevent further deterioration of the RCPB.

B.1 and B.2 If any pressure boundary LEAKAGE exists or primary to secondary LEAKAGE is not within limits, or if unidentified or identified LEAKAGE cannot be reduced to within limits within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, the reactor must be placed in a lower pressure condition to reduce the severity of the LEAKAGE and its potential consequences.

The reactor must be placed in MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

This action reduces the LEAKAGE and also reduces the stresses that tend to degrade the pressure boundary.

The Completion Times allowed are reasonable, based on operating experience, to reach the required conditions from full power conditions in an orderly manner and without challenging plant systems.

In MODE 5, the pressure stresses acting on the RCPB are much lower and further deterioration is much less likely.

OTSG Tube Integrity B 3.4.16 B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.16 Steam Generator (OTSG)

Tube Integrity BASES BACKGROUND Steam generator (OTSG) tubes are small diameter, thin walled tubes that carry primary coolant through the primary to secondary heat exchanges.

The OTSG tubes have a number of important safety functions.

Steam generator tubes are an integral part of the reactor coolant pressure boundary (RCPB) and, as such, are relied on to maintain the primary system's pressure and inventory.

The OTSG tubes isolate the radioactive fission products in the primary coolant from the secondary system.

In addition, as part of the RCPB, the OTSG tubes are unique in that they act as the heat transfer surface between the primary and secondary systems to remove heat from the primary system.

This Specification addresses only the RCPB integrity function of the OTSG.

The OTSG heat removal function is addressed by LCO 3.4.4, "RCS Loops -

MODE 3,"

LCO 3.4.5, "RCS Loops -

MODE 4," LCO 3.4.6, "RCS Loops -

MODE 5, Loops Filled," and is implicitly required in MODES 1 and 2 in order to prevent a Reactor Protection System actuation (LCO 3.3.1).

OTSG tube integrity means that the tubes are capable of performing their intended RCPB safety function consistent with the licensing basis, including applicable regulatory requirements.

Steam generator tubing is subject to a variety of degradation mechanisms.

Steam generator tubes may experience tube degradation related to corrosion phenomena, such as wastage, pitting, intergranular attack, and stress corrosion cracking, along with other mechanically induced phenomena such as denting and wear.

These degradation mechanisms can impair tube integrity if they are not managed effectively.

The OTSG performance criteria are used to manage OTSG tube degradation.

Specification 5.6.2.10, "Steam Generator (OTSG)

Program,"

requires that a program be established and implemented to ensure that OTSG tube integrity is maintained.

Pursuant to Specification 5.6.2.10, tube integrity is maintained when the OTSG performance criteria are met.

There are three OTSG performance criteria: structural integrity, accident induced leakage, and operational LEAKAGE.

The OTSG (continued)

Crystal River Unit 3 B 3.4-75 Revision No.

OTSG Tube Integrity B 3.4.16 BASES BACKGROUND performance criteria are described in Specification (continued) 5.6.2.10.

Meeting the OTSG performance criteria provides reasonable assurance of maintaining tube integrity at normal and accident conditions.

The processes used to meet the OTSG performance criteria are defined by the Steam Generator Program Guidelines (Ref.

1).

APPLICABLE SAFETY ANALYSES The steam generator tube rupture (SGTR) accident is the limiting design basis event for OTSG tubes and avoiding an SGTR is the basis for this Specification.

The analysis of a SGTR event assumes a bounding primary to secondary LEAKAGE rate equal to the operational LEAKAGE rate limits in LCO 3.4.12, "RCS Operational LEAKAGE,"

plus the leakage rate associated with a double-ended rupture of a single tube.

The accident analysis for a SGTR assumes the contaminated secondary fluid is only briefly released to the atmosphere via safety valves and the majority is discharged to the main condenser.

The analysis for design basis accidents and transients other than a SGTR assume the OTSG tubes retain their structural integrity (i.e., they are assumed not to rupture).

In these analyses, the steam discharge to the atmosphere is based on the total primary to secondary LEAKAGE from all OTSGs of one gallon per minute or is assumed to increase to one gallon per minute as a result of accident induced conditions.

For accidents that do not involve fuel damage, the primary coolant activity level of DOSE EQUIVALENT 1-131 is assumed to be equal to the LCO 3.4.15, "RCS Specific Activity," limits.

For accidents that assume fuel damage, the primary coolant activity is a function of the amount of activity released from the damaged fuel.

The dose consequences of these events are within the limits of GDC 19 (Ref.

2),

10 CFR 50.67 (Ref.

3) or the NRC approved licensing bases (e.g., a small fraction of these limits).

Steam generator tube integrity satisfies Criterion 2 of 10 CFR 50.36(c)(2)(ii).

LCO The LCO requires that OTSG tube integrity be maintained.

The LCO also requires that all OTSG tubes that satisfy the repair criteria be plugged or repaired in accordance with the Steam Generator Program.

OTSG Tube Integrity B 3.4.16 BASES LCO During an OTSG inspection, any inspected tube that (continued) satisfies the Steam Generator Program repair criteria is repaired or removed from service by plugging.

If a tube was determined to satisfy the repair criteria but was not plugged or repaired, the tube may still have tube integrity.

In the context of this Specification, an OTSG tube is defined as the entire length of the tube, including the tube wall and any repairs made to it, between the tube-to-tubesheet weld at the tube inlet and the tube-to-tubesheet weld at the tube outlet.

The tube-to-tubesheet weld is not considered part of the tube.

An OTSG tube has tube integrity when it satisfies the OTSG performance criteria.

The OTSG performance criteria are defined in Specification 5.6.2.10, "Steam Generator Program," and describe acceptable OTSG tube performance.

The Steam Generator Program also provides the evaluation process for determining conformance with the OTSG performance criteria.

There are three OTSG performance criteria: structural integrity, accident induced leakage, and operational LEAKAGE.

Failure to meet any one of these criteria is considered failure to meet the LCO.

The structural integrity performance criterion provides a margin of safety against tube burst or collapse under normal and accident conditions, and ensures structural integrity of the OTSG tubes under all anticipated transients included in the design specification.

Tube burst is defined as, "The gross structural failure of the tube wall.

The condition typically corresponds to an unstable opening displacement (e.g., opening area increased in response to constant pressure) accompanied by ductile (plastic) tearing of the tube material at the ends of the degradation."

Tube collapse is defined as, "For the load displacement curve for a given structure, collapse occurs at the top of the load versus displacement curve where the slope of the curve becomes zero."

The structural integrity performance criterion provides guidance on assessing loads that have a significant effect on burst or collapse.

In that context, the term "significant" is defined as "An accident loading condition other than differential pressure (continued)

Crystal River Unit 3 B 3.4-77 Revision No.

OTSG Tube Integrity B 3.4.16 BASES LCO (continued) is considered significant when the addition of such loads in the assessment of the structural integrity performance criterion could cause a lower structural limit or limiting burst/collapse condition to be established."

For tube integrity evaluations, except for circumferential degradation, axial thermal loads are classified as secondary loads.

For circumferential degradation, the classification of axial thermal loads as primary or secondary loads will be evaluated on a case-by-case basis.

The division between primary and secondary classifications will be based on detailed analysis and/or testing.

Structural integrity requires that the primary membrane stress intensity in a tube not exceed the yield strength for all ASME Code,Section III, Service Level A (normal operating conditions) and Service Level B (upset or abnormal conditions) transients included in the design specification.

This includes safety factors and applicable design basis loads based on ASME Code,Section III, Subsection NB (Ref.

4) and Draft Regulatory Guide 1.121 (Ref.

5).

The accident induced leakage performance criterion ensures that the primary to secondary LEAKAGE caused by a design basis accident, other than a SGTR, is within the accident analysis assumptions.

The accident analysis assumes that accident induced leakage does not exceed one gallon per minute per OTSG.

The accident induced leakage rate includes any primary to secondary LEAKAGE existing prior to the accident in addition to primary to secondary LEAKAGE induced during the accident.

The operational LEAKAGE performance criterion provides an observable indication of OTSG tube conditions during plant operation.

The limit on operational LEAKAGE is contained in LCO 3.4.12, "RCS Operational LEAKAGE,"

and limits primary to secondary LEAKAGE through any one OTSG to 150 gallons per day.

This limit is based on the assumption that a single crack leaking this amount would not propagate to a SGTR under the stress conditions of a LOCA or a main steam line break.

If this amount of LEAKAGE is due to more than one crack, the cracks are very small, and the above assumption is conservative.

Crystal River Unit 3 B 3.4-78 Revision No.

OTSG Tube Integrity B 3.4.16 BASES APPLICABILITY Steam generator tube integrity is challenged when the pressure differential across the tubes is large.

Large differential pressures across OTSG tubes can only be experienced in MODE 1, 2,

3, or 4.

RCS conditions are far less challenging in MODES 5 and 6 than during MODES 1, 2,

3, and 4.

In MODES 5 and 6, primary to secondary differential pressure is

low, resulting in lower stresses and reduced potential for LEAKAGE.

ACTIONS The ACTIONS are modified by a Note clarifying that the Conditions may be entered independently for each OTSG tube.

This is acceptable because the Required Actions provide appropriate compensatory actions for each affected OTSG tube.

Complying with the Required Actions may allow for continued operation, and subsequent affected OTSG tubes are governed by subsequent Condition entry and application of associated Required Actions.

A.1 and A.2 Condition A applies if it is discovered that one or more OTSG tubes examined in an inservice inspection satisfy the tube repair criteria but were not plugged or repaired in accordance with the Steam Generator Program as required by SR 3.4.16.2.

An evaluation of OTSG tube integrity of the affected tube(s) must be made.

Steam generator tube integrity is based on meeting the OTSG performance criteria described in the Steam Generator Program.

The OTSG repair criteria define limits on OTSG tube degradation that allow for flaw growth between inspections while still providing assurance that the OTSG performance criteria will continue to be met.

In order to determine if an OTSG tube that should have been plugged or repaired has tube integrity, an evaluation must be completed that demonstrates that the OTSG performance criteria will continue to be met until the next refueling outage or OTSG tube inspection.

The tube integrity determination is based on the estimated condition of the tube at the time the situation is discovered and the estimated growth of the degradation prior to the next OTSG tube inspection.

If it is determined that tube integrity is not being maintained, Condition B applies.

(continued)

Crystal River Unit 3 B 3.4-79 Revision No.

OTSG Tube Integrity B 3.4.16 BASES ACTIONS A.1 and A.2 (continued)

A Completion Time of 7 days is sufficient to complete the evaluation while minimizing the risk of plant operation with an OTSG tube that may not have tube integrity.

If the evaluation determines that the affected tube(s) have tube integrity, Required Action A.2 allows plant operation to continue until the next refueling outage or OTSG inspection provided the inspection interval continues to be supported by an operational assessment that reflects the affected tubes.

However, the affected tube(s) must be plugged or repaired prior to entering MODE 4 following the next refueling outage or OTSG inspection.

This Completion Time is acceptable since operation until the next inspection is supported by the operational assessment.

B.1 and B.2 If the Required Actions and associated Completion Times of Condition A are not met or if OTSG tube integrity is not being maintained, the reactor must be brought to MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

The allowed Completion Times are reasonable, based on operating experience, to reach the desired plant conditions from full power conditions in an orderly manner and without challenging plant systems.

SURVEILLANCE SR 3.4.16.1 REQUIREMENTS During shutdown periods the OTSGs are inspected as required by this SR and the Steam Generator Program.

NEI 97-06, Steam Generator Program Guidelines (Ref. 1),

and its referenced EPRI Guidelines, establish the content of the Steam Generator Program.

Use of the Steam Generator Program ensures that the inspection is appropriate and consistent with accepted industry practices.

During OTSG inspections a condition monitoring assessment of the OTSG tubes is performed.

The condition monitoring assessment determines the "as found" condition of the OTSG tubes.

The purpose of the condition monitoring assessment is to ensure that the OTSG performance criteria have been met for the previous operating period.

OTSG Tube Integrity B 3.4.16 BASES SURVEILLANCE SR 3.4.16.1 (continued)

REQUIREMENTS The Steam Generator Program determines the scope of the inspection and the methods used to determine whether the tubes contain flaws satisfying the tube repair criteria.

Inspection scope (i.e., which tubes or areas of tubing within the OTSG are to be inspected) is a function of existing and potential degradation locations.

The Steam Generator Program also specifies the inspection methods to be used to find potential degradation.

Inspection methods are a function of degradation morphology, non-destructive examination (NDE) technique capabilities, and inspection locations.

The Steam Generator Program defines the Frequency of SR 3.4.16.1.

The Frequency is determined by the operational assessment and other limits in the OTSG examination guidelines (Ref.

6).

The Steam Generator Program uses information on existing degradations and growth rates to determine an inspection Frequency that provides reasonable assurance that the tubing will meet the OTSG performance criteria at the next scheduled inspection.

In addition, Specification 5.6.2.10 contains prescriptive requirements concerning inspection intervals to provide added assurance that the OTSG performance criteria will be met between scheduled inspections.

SR 3.4.16.2 During an OTSG inspection, any inspected tube that satisfies the Steam Generator Program repair criteria is repaired or removed from service by plugging.

The tube repair criteria delineated in Specification 5.6.2.10 are intended to ensure that tubes accepted for continued service satisfy the OTSG performance criteria with allowance for error in the flaw size measurement and for future flaw growth.

In addition, the tube repair criteria, in conjunction with other elements of the Steam Generator Program, ensure that the OTSG performance criteria will continue to be met until the next inspection of the subject tube(s).

Reference 1 provides guidance for performing operational assessments to verify that the tubes remaining in service will continue to meet the OTSG performance criteria.

Steam generator tube repairs are only performed using approved repair methods as described in the Steam Generator Program.
