{{#Wiki_filter:0 0 0 S 0** Section 6: Surveillance Program Status 0 and Recommendations 0A description of the surveillance materials and current RVSP of all the U.S.* PWRs along with the recommended program for the CRVSP is contained in*this section. For each plant, the existing RVSP and results to date (e.g., capsules tested, and fluence) are reviewed, and then the recommended changes (if any) are 0discussed. | |||
The following plants are not included in this section because these plants have no remaining capsules: | |||
Arkansas Nuclear One Unit 1, Oconee Units 1-3, and Three Mile Island Unit 1. A total of 16 capsules were tested at these plants and all of the withdrawal fluences were below 1.8x10 1 9 n/cm 2 , which is less* than the fluence range of interest for this program (3x10`9 to 10xl0 9 n/cm 2).*These plants participate in the B&W Master Integrated Reactor Vessel Surveillance Program (MIRVP) [15, 16].*The CRVSP will continue to allow the MIRVP plants to participate in the B&W Master Integrated Reactor Vessel Surveillance Program. Surry Unit 2 and*Turkey Point Unit 4 are the only MIRVP participants to which the CRVSP*makes recommended changes to the plant specific RVSP. The MIRVP does not require Surry Unit 2 to test any additional capsules, so the CRVSP recommendation for Surry Unit 2 to test an additional capsule does not* negatively impact the MIRVP. The MIRVP states that Turkey Point Unit 4 will test capsule X at the end of cycle 27, which is between once and twice the projected 60-year peak RPV fluence. The CRVSP recommends that Turkey*Point Unit 4 test capsule X at the projected 80-year peak RPV fluence, which is between once and twice the projected 60-year peak RPV fluence. Since Turkey Point is the only MIRVP participant that will use the data from capsule X, this*recommended change does not negatively impact the MIRVP.Where changes to existing RVSPs have been recommended as part of this 0optimized, coordinated program, they are identified as bulleted items in the 5"Recommended Program" discussion for each plant.*When changes to a plant's RVSP capsule withdrawal schedule are recommended,*those recommendations are expressed in terms of the plant's peak RPV fluence at*some future time in life. For example, a recommendation may be made to defer capsule withdrawal from a planned date of 2016 to a future time when the Scapsule has attained a fluence equal to that plant's 80 year peak RPV fluence. To implement that recommendation, the plant determines the appropriate outage<6-1 >0 0 0 S 0 (or year) to withdraw the capsule in order to achieve that fluence, based on its 0 current fluence and capacity factor projections and using the same methodology that would be used to. calculate, for example, the appropriate withdrawal date for*its 60 year license renewal capsule.*After recommended changes are identified (bulleted items in the "Recommended Program" section for each plant), a "Discussion" is generally provided that describes the estimated withdrawal date(s) and capsule fluence(s) that would be achieved by implementation of the recommendations. | |||
These estimates are for*coordinated planning purposes only -used by the CRVSP to estimate capsule data availability to fill high fluence data gaps -and are not meant for any other*analysis. | |||
Final determination of the appropriate capsule withdrawal year that*achieves the CRVSP recommendation is the responsibility of the plant, based on data deemed by the plant to be authoritative and appropriate. | |||
For many plants, the statement provided in the "Recommended Program" section may be "No changes are recommended to the current capsule withdrawal plan, test schedule, or related commitments." This statement is intended to*address whether or not a change is recommended in order to obtain the*objectives of the CRVSP. The statement is not intended to discourage any plant from taking an appropriate action to increase the amount of surveillance data or the fluence level of surveillance data if the plant deems such an action to be in its*best interest and compliant with 10 CFR 50 Appendix H [3] requirements. | |||
For example, this report may provide a discussion that consideration was given to asking a plant to move a capsule from the spent fuel pool back into the reactor for further irradiation, but that it was decided not to make that recommendation. | |||
Moving the capsule may be in the plant's best long-term interest, and there is no intent to discourage such an action, even though the CRVSP did not deem it*necessary for the objectives of the CRVSP.0Arkansas Nuclear One Unit 2 0*Material Description | |||
*Six surveillance capsules containing beltline materials fabricated from ASME*SA-533, Grade B, Class 1 (low Cu) and weld flux Linde 91 (low Cu) were*inserted in the reactor prior to initial start-up [19, 20].0Current Program Two of the original six surveillance capsules (W-97 and W-104) have been*removed and tested, [19]. The lead factor of 1.47 for capsule W-104 was calculated using the capsule fluence (2.937x10 1 9 n/cm 2) and the peak RPV at the time of capsule removal (2.001xlO' 9 n/cm 2) [19]. The lead factor for capsule W-284 is assumed to be the same as capsule W-104 based on the symmetry of the*capsule locations | |||
[19]. Arkansas Nuclear One (ANO) Unit 2 received approval*for a 60-year (48 EFPY) license renewal in 2005, which requires a standby capsule be removed at the fluence equivalent to EOL peak RPV fluence of* 5.277x10'9 n/cm 2 [21].<6-2>0 0 0 0 0 S 0 0 Using the capsule lead factor and the linear relationship between EFPY and the peak RPV fluence, the EFPY required for capsule W-284 to reach 5.277x10 9 n/cm2 was calculated to be 29.8. This linear relationship was based on 3.791x10'9* n/cm 2 at 32 EFPY and 5.580x10 9 n/cm 2 at 48 EFPY [19].

Supplemental capsule A should be removed during the first scheduled outage after the capsule is estimated to attain a fluence equal to the BV1 projected 80-year peak RPV fluence. At a minimum, the BV1 capsule Y Linde 1092 weld metal contained in capsule A should then be tested.Discussion BV2 Capsule A: The following information was provided by the utility for the purpose of developing the CRVSP. The projected 80-year (68 EFPY) peak RPV fluence for BV1 is 7.62x10 1 9 n/cm 2.Capsule A will reach a fluence of 7.67x10'9 n/cm 2 in 2025 (32 EFPY). The previously irradiated material from BV1 capsule Y contained in capsule A will have an approximate cumulative fluence of 9.72x10 1 9 n/cm 2 in 2025. The projections resulting from these estimations are shown in the table below.Testing additional BV1 surveillance material is not required for the BV1 60-year license, but it could support a potential BV1 license renewal to 80 years. Testing the BV1 capsule Y Linde 1092 weld metal contained in capsule A will help fill high fluence data gaps in the Linde 1092 (high Cu) material group, as shown in Figure 4-13.<6-5> | |||
S 0 S 0* BV2 Capsule Y:* 'As noted above, plant personnel provided input during development of the* CRVSP that testing of Capsule Y is already planned by the plant. Therefore,* testing Capsule Y is not identified as a recommended change because it is not a change from the current program. However, testing Capsule Y makes a valuable* contribution to the CRVSP and warrants additional discussion. | |||
Although testing* an additional capsule is not required for the BV2 60-year license, testing capsule Y or Z as currently planned will help fill high fluence data gaps in the SA-533* (low Cu) and Linde 91 (low Cu) material groups, as shown in Figure 4-1 and* Figure 4-9.* Table 6-4* Beaver Valley Unit 2 Estimated Results of Recommended Changes to Withdrawal Schedule......... | |||

Discussion The value of reinserting Capsule V and continuing irradiation to achieve a higher 0fluence was assessed, but that action is not recommended because the benefit to the plant or the PWR surveillance database (SDB) is low. The remaining capsules contain low copper SA-508 base metal and low copper Linde 80 weld metal. High fluence surveillance data will be well represented in the low copper* SA-508 category above the projected 2x60-year peak RPV fluence of 6.6x10 9 n/cm 2 without the Capsule V data. The low copper Linde 80 weld metal is unique to Braidwood and Byron units. Therefore, reinsertion of Capsule V for*further irradiation provides minimal benefit to the PWR fleet SDB.Furthermore, the data will be available when the capsule is tested for license renewal, if the plant applies for a renewed license. Therefore, there is no need for 0the CRVSP to recommend any change to the Braidwood 1 RVSP. When the need develops in the future to test a capsule, however, it is suggested that preferential consideration be given to testing the capsule with highest fluence.0 0 0 0 0 0 0 0~<6-7 *0 0 0 0 0 0 0* Braidwood Unit 2*Material Description 0 Six surveillance capsules containing beltline materials fabricated from ASME SA-508 Class 3 (low Cu) and Linde 80 flux (low Cu) were inserted in the reactor*prior to initial start-up [27].0Current Program* Half of the original surveillance capsules (U, X and W) have been removed and tested while capsules Z and Y have been removed without testing, Table 6-6[26].

*For the purpose of developing the CRVSP, the projected capsule fluence and year of withdrawal were estimated as follows: The estimated removal fluence value of 5.66x10'9 n/cm 2 is twice the 60-year (48 EFPY) RPV peak fluence of*2.83x10 1 9 n/cm 2.The EFPY of capsule S at 5.66x10 1 9 n/cm 2 was estimated to be*about 36 by using the cumulative lead factor at 36 EFPY (2.7) and the projected peak RPV fluence at 36 EFPY (2.06x10 1 9 n/cm 2) [46].

Capsule B should be removed at the last outage before the capsule is estimated to receive a neutron fluence equal to two times the peak RPV neutron fluence at the end of the period of extended operation. | |||
Capsule B should then be tested.Discussion For the purpose of developing the CRVSP, the projected 2x60-year peak RPV fluence and year of withdrawal were estimated as follows: The removal fluence value of 4.12x10 1 9 n/cm 2 is twice the 60-year (54 EFPY) RPV peak fluence of 2.06x10 1 9 n/cm 2 [49]. Using the capsule lead factor and linear relationship between the reported peak RPV fluences and their corresponding EFPY values, the EFPY required for capsule B to go from 3.23x10 1 9 n/cm 2 to 4.12x10'9 n/cm 2 was calculated to be 7 EFPY. Assuming a 0.95 capacity factor starting in 2002 and the projected removal EFPY of 30.2, the capsule will reach the specified fluence in about 2018. The projections resulting from these estimations are shown in the table below. The plant is responsible for formal determination of the planned withdrawal year, based on the latest RPV fluence data.< 6-23 > | |||

M Capsule W-275S should be removed at 47.2 EFPY (rather than at 33.6*EFPY) to obtain higher fluence data for the limiting RV welds. [See note in Discussion.] | |||
*I Discussion | |||
*For the purpose of developing the CRVSP, the projected 80-year peak RPV*fluence and year of withdrawal were estimated as follows: The 80-year (67 EFPY) fluence of 4.72x10 9 n/cm 2 was extrapolated from the linear relationship between the peak RPV fluence and the corresponding EFPY values. The 67*EFPY value was determined by assuming a 0.95 capacity factor starting after 60 years of operation. | |||
Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and their corresponding EFPY values,* capsule W-45 should reach the specified fluence at 42 EFPY, which will occur in*about 2022. The projections resulting from these estimations are shown in the<6-27 )0 0 0 0 0 0 0 table below. The plant is responsible for formal determination of the planned 0year of withdrawal, based on latest vessel fluence data.Note: The change in withdrawal schedule for W-275S from 33.6 EFPY to 47.2 0EFPY is not a recommendation from the CRVSP and is not required to obtainthe objectives of the CRVSP; it was added to the list of recommended changes at*the request of the plant.*Table 6.27 Fort Calhoun Estimated Results of Recommended Changes and Plant's Changes to Withdrawal Schedule 00 Capule Loctio Led simateiReova MEstim ted-0.Factr Reova (EFY) luence 0* W-45 450 1.51 ...2022 ... .40 4...!7200°'9(a) | |||

Discussion 9* For the purpose of developing the CRVSP, the projected 80-year peak RPV fluence and withdrawal year were estimated as follows: The projected EFPY for 0 the 80-year license was determined using a conservative capacity factor of 0.95.* Based on the 32 EFPY fluence of 3.37x10" 9 n/cm 2 and the 60-year (54 EFPY)fluence of 5.162x10 1 9 n/cm 2 [93], the 80-year (73 EFPY) peak RPV fluence was determined by extrapolation to be 6.7x101 9 n/cm 2.For the purpose of this O discussion, it is assumed that Capsule T will be withdrawn, although the plant* may choose to withdraw Capsule N. Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and their corresponding O EFPY values, the EFPY required for capsule T to reach 6.7x10 1 9 n/cm 2 was 9 calculated to be 34.1. Assuming a 0.95 capacity factor starting in 1996 and the projected removal EFPY of 34.1, capsule T should reach the specified fluence in*about 2013.

*1 Discussion For the purpose of developing the CRVSP, the projected 80-year peak RPV 0fluence and removal year were estimated as follows: The projected EFPY for the 80-year license was determined using a conservative capacity factor of 0.95. Based* on the 32 EFPY fluence of 3.32x10 1 9 n/cm 2 and the 60-year (54 EFPY) fluence of 5.196x10 9 n/cm 2 [93], the 80-year (73 EFPY) peak RPV fluence was determined by extrapolation to be 6.82x101 9 n/cm 2.Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and their corresponding EFPY values, the EFPY required for capsule N to reach 6.82x10 1 9*n/cm 2 was calculated to be 39.5. Assuming a 0.95 capacity factor starting in 1997*and the projected removal EFPY of 39.5, capsule N should reach the specified fluence in about 2020.

*For the purpose of developing the CRVSP, the projected 40-year peak RPV*fluence and year of withdrawal were estimated as follows: The projected 40-year (32 EFPY) peak RPV fluence is 4.19x101 9 n/cm 2 [106]. Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and*their corresponding EFPY values, the EFPY required for capsule 830 to reach 4.19x101 9 n/cm 2 was extrapolated to be 26.5 EFPY. This linear relationship is based on 2.01x10'9 n/cm 2 at 14.93 EFPY and 4.19x10 1 9 n/cm 2 at 32 EFPY*[106]. Assuming a 0.95 capacity factor starting in 2003 and the projected removal EFPY of 26.5, capsule 830 should reach the specified fluence in about 2016.

Assuming a 0.95 capacity factor starting in 2005 and the projected removal EFPY of 26.13, capsule X should reach the specified fluence in about 2019.

0 0 DiscussionFor the purpose of developing the CRVSP, the projected 2x60-year peak RPV fluence and year of withdrawal were estimated as follows: The projected EFPY for the 60-year license was determined using a conservative capacity factor of 0.95. Based on the 60-year (54 EFPY) fluence of 3.01xl0 1 9 n/cm 2 , twice the 60-* year (54 EFPY) peak RPV fluence was determined to be 6.02x10'9 n/cm 2.Using the capsule lead factor and the linear relationship between the reported peak*RPV fluences and their corresponding EFPY values, the EFPY required for capsule V to reach 6.02x10'9 n/cm 2 was calculated to be 25.7. Assuming a 0.95 capacity factor starting in 2006 and the projected removal EFPY of 25.7, capsule V should reach the specified fluence in about 2023. The projections resulting*from these estimations are shown in the table below. The plant is responsible for determination of the actual removal year, based on the latest RPV fluence data.*Table 6-78 Watts Bar Estimated Results of Recommended Changes to Withdrawal Schedule 058.50 4.31 2023 25.7 6.02x1019(a)(a) Twice projected 60-year (54 EFPY) peak RPV fluence.*Wolf Creek Unit 1*Material Description | |||

The CRVSP does not reduce, alter, or otherwise affect each plant's*responsibility to comply with 10 CFR 50 Appendix H[3] and relevant licensing commitments, but it may require a plant to submit a request to the NRC to modify the details (e.g., schedule) of how the plant will comply with Appendix H*and applicable license commitments. | |||
0 NEI 03-08 Implementation Protocol This program is a 'work product' of the EPRI MRP, an 'Issue Program (IP)' as defined in NEI 03-08 [5]. Addendum D to NEI 03-08, Implementation Protocol, defines the processes and expectations for implementing industry*guidance issued under the Materials Initiative, and requires that IPs identify the*specific implementation category for 'requirements' identified guideline-type work products.*The three implementation categories described in NEI 03-08 are as follows:* Mandatory-to be implemented at all plants where applicable; | |||
* Needed -to be implemented wherever possible, but alternative approaches | |||
*are acceptable; and* Good Practice -implementation is expected to provide significant operational and reliability benefits, but the extent of use is at the discretion of*the individual utility.*The CRVSP recommended changes detailed in Section 6 of this report have 0been designated as "Needed" requirements, as explained below. A failure to meet 9a Needed requirement is a deviation from the guidelines and a written justification for the deviation must be prepared and approved as described inAppendix B to NEI 03-08 [5]. A copy of the deviation is sent to the MRP so*that improvements to the guidelines can be developed. | |||
0Implementation of this guidance as a Needed requirement is justified because the*ability of the CRVSP to achieve the objectives of obtaining higher fluence PWR surveillance data is dependent on all plants with recommended changes implementing those recommendations. | |||
It was discussed earlier in this report that*the paucity of high fluence PWR data without the CRVSP is likely to result in an embrittlement trend correlation based in large part on test reactor data at<7-1 >0 0 0 0 | |||
*0 fluences above 3x10 1 9 n/cm 2; such an ETC could result in significantly increased* RPV embrittlement predictions because test reactor data typically exhibits higher rates of embrittlement. | |||
This in turn could have significant financial impact on the industry, ranging from increased startup/shutdown times and costs (and regulatory action) to the possible need for some plants to mitigate RPV 0embrittlement resulting from application of embrittlement correlations that are not representative of power reactor trends. The Yankee Rowe experience clearly demonstrated the ability of RPV embrittlement issues to shorten the useful*financial life of a unit. Thus, the issue fulfills either of the following conditions | |||
*for implementation under the "Needed" category:* "Element addresses a material degradation mechanism | |||
[neutron embrittlement] | |||
that has significant financial impact on the entire industry, especially where failure at one plant could affect many other plants.M A consensus of the responsible materials IP believes the element should be designated | |||
*as 'Needed"." 0Coordinated Surveillance Program Requirement | |||
* Needed: Following issuance ofMRP-326, Rev. 0, each commercial US. PWR unit for which a change to its reactor vessel surveillance program has been recommended in Section 6 shall Submit a request to the NRC to revise the plant's surveillance capsule program and/or schedule as required to implement the recommendation(s). | |||
The changes covered by this requirement are presented as bulleted items in the 'Recommended Program" section for each plant in Section 6; plants with no bulleted recommendations require no action. When submission ofprogram change request is* required, the submission shall be made per the following schedule.- | |||
-If the change affects a capsule withdrawal/test which is scheduled before January 1, 2014, the request should be submitted to the NRC no later than ten* months following the issuance ofMRP-326, Rev. 0.-If the change affects a capsule withdrawal/test which is scheduled after January 1, 2014, the request should be submitted to the NRC no earlier than ten months nor later than 18 months after issuance ofMRP-326, Rev. 0.0 The phased submission of RVSP change requests to the NRC will make the flow of requests arrive in general order of calendar urgency and will permit plants with*near-term needs to receive priority review.*An optional template for use in generating the letter request to the NRC is*provided in Appendix B of this document. | |||
The template provides a format that*will demonstrate the plant's continued compliance with 10 CFR 50, Appendix H, after implementation of the recommended changes.0 0 0~<7-2>*0 0 0 0 0 0 0 0 0* Section 8: References | |||

S. Nuclear Regulatory Commission ATTN: Document Control Desk*Washington, DC 20555* [Plant name]*[Docket Number][License number]* Revision to Reactor Vessel Surveillance Capsule Withdrawal Schedule 0Pursuant to 10 CFR 50, Appendix H, 1m1.C.3, [Owner name] is requesting Nuclear Regulatory 0Commission (NRC) review and approval of the enclosed revision to the surveillance capsule removal schedule for [plant name]. The proposed reactor vessel surveillance capsule removal schedule was developed to implement recommendations for [plant name] in MRP-326, CoordinatedPWR Reactor Vessel*Surveillance Program (CR VSP) Guidelines. | |||
MRP-326 addresses the need for reactor vessel property data at fluences representative of 60 years of operation and beyond for [Plant Name] and the industry. | |||
The requested change to the Appendix H program for [Plant Name] satisfies the requirements of 10 CFR 50, Appendix H and ASTM E-185-82, "Standard Practice for Conducting Surveillance Tests for Light-Water Cooled Nuclear Power Reactor Vessels", dated July 1, 1982, and is consistent with the guidance of*NUREG-1801, Rev. 2, Generic Aging Lessons Learned 0Approval of this proposed change is requested no later than [date].0Summary of Commitments This letter contains no new commitments and no revisions to existing commitments. | |||
[if applicable](License renewal commitments and issues should be looked at and addressed, if applicable) 0 0 0 0 9 0 0 0 0 0 0 0 0 0 0 0 0 ENCLOSURE*REVISION TO REACTOR VESSEL SURVEILLANCE PROGRAM* [PLANT NAME]I. BackgroundAppendix H to 10 CFR Part 50 describes reactor vessel material surveillance program requirements. | |||
Paragraph (III)(B)(3) of this Appendix states that a proposed material withdrawal schedule must be 0 submitted with a technical justification per 10 CFR 50.4, and approved prior to implementation. | |||
0 Industry has developed a Coordinated PWR Reactor Vessel Surveillance Program (CRVSP), which is* documented in MRP-326, Coordinated PWR Reactor Vessel Surveillance Program (CR VSP) Guidelines. | |||
The purpose of the CRVSP is to increase the fluence levels of future surveillance capsules at withdrawal while*maintaining compliant with 10 CFR 50 Appendix H and consistent with the guidance of NUREG-1801, Rev. 2, GALL Report. The CRVSP will help generate high fluence PWR surveillance data in support of extended life operations. | |||
The proposed withdrawal schedule satisfies the requirements of American Society for Testing and*Materials (ASTM) E 185-xx, the version that was current at the time the reactor vessel surveillance | |||
*program was designed.Table (1) shows the currently approved withdrawal schedule for [plant name] reactor vessel surveillance | |||
*capsules (Updated Final Safety Analysis Report Table x-xx).0 II. Proposed Revision 0 Table (2) provides the proposed revision to the reactor vessel surveillance capsule withdrawal schedule for[plant name]. The revised schedule is based on the recommendations for [plant name] in MRP-326, and reflects updated fluence information from the surveillance capsule removed in [year] with appropriate adjustment made for fuels loaded in subsequent cycles. As shown below in Section III, the proposed withdrawal schedule satisfies the requirements of ASTM E 185-xx, the version that was current at the time the reactor vessels were designed. | |||
Therefore, the withdrawal schedule satisfies the requirements of*Appendix H to 10 CFR Part 50.0 III. Justification 0The [plant name] reactor vessel was designed to the [year] through [idenity of applicable addenda]*Addenda, edition of the American Society of Mechanical Engineers Code. American Society for Testing and Materials E 185-xx was the current standard when the surveillance program was designed. | |||
As stated in the [Plant name] Updated Final Safety Analysis Report, the reactor vessel surveillance program meets*the requirements of ASTM E 185-xx.The guidance provided in ASTM E 185-82 is consistent with, but more specific than, the guidance*provided in earlier editions, including ASTM E 185-xx to which the [plant name] reactor vessel*surveillance program is required to conform. Therefore, compliance with the ASTM E185-82 withdrawal schedule guidance ensures compliance with ASTM E 185-xx withdrawal schedule guidance. | |||
ASTM E 0 0 0 0 0 0 0 185-82 provides a withdrawal schedule in terms of years of operation but also provides the option to 0 develop a schedule tied to target fluences accumulated in the vessel. As in the case of the currently approved withdrawal schedule, the proposed withdrawal schedule follows the guidance that ties the withdrawal schedule to vessel fluence targets.0 This request proposes to revise the reactor vessel surveillance capsule withdrawal schedule to [detail the specific change as recommended byMRP-326]. | |||
A detailed explanation of the change for [plant name] is provided in MRP-326.* The [capsule name] capsule meets the requirements of ASTM E 185-82 to withdraw the third capsule at a time when the accumulated neutron fluence on the capsule corresponds to the approximate end of life peak fluence at the reactor vessel 1 T location. | |||
As noted on Table (2), we would withdraw the [capsule name] capsule during the [year or RFO number] refueling outage and designate the [capsule name] capsule as the standby capsule [if applicable]. | |||
This proposed change meets the requirements of Appendix H to 10 CFR Part 50.* If applicable: | |||
[Plant name] received approval of license renewal in [year]. The [plant name] license renewal application (LRA) referenced GALL Revision 1, and Capsule [capsule name] was identified as the capsule to be tested to meet the recommendations of GALL Rev. 1. GALL Rev. 1 recommends that the plant"...withdraws one capsule at an outage in which the capsule receives a neutron fluence equivalent to the 60-year fluence...." As aresult, the current capsule withdrawal schedule is based on withdrawing Capsule[capsule name] at Refueling Outage (RFO)-xx. | |||
NUREG-1801, Rev. 2 (GALL Report) recommends that 0* e "The plant-specific or integrated surveillance program shall have at least one capsule with a projected neutron fluence equal to or exceeding the 60-year peak reactor vessel wall neutron 0 fluence prior to the end of the period of extended operation. | |||
The program withdraws one capsule at an outage in which the capsule receives a neutron fluence of between one and two times the peak reactor vessel wall neutron fluence at the end of the period of extended operation and tests* the capsule in accordance with the requirements of ASTM E 185-82.""Plant-specific and fleet operating experience should be considered in determining the withdrawal schedule for all capsules..." 0 The proposed withdrawal date for Capsule [capsule name] meets both of these recommendations. | |||
The operating experience of both [Plant name] and the U.S. PWR fleet were considered in the development of the revised capsule withdrawal schedule, as discussed in MRP-326. The capsule fluence at the proposed 0 withdrawal date will meet the guidance that the license renewal capsule should achieve a fluence between one and two times the peak reactor vessel wall neutron fluence at the end of the period of extended* operation. | |||
* [I[f applicable.] | |||

0 0 0 S 0** Section 6: Surveillance Program Status 0 and Recommendations 0A description of the surveillance materials and current RVSP of all the U.S.* PWRs along with the recommended program for the CRVSP is contained in*this section. For each plant, the existing RVSP and results to date (e.g., capsules tested, and fluence) are reviewed, and then the recommended changes (if any) are 0discussed.
The following plants are not included in this section because these plants have no remaining capsules:
Arkansas Nuclear One Unit 1, Oconee Units 1-3, and Three Mile Island Unit 1. A total of 16 capsules were tested at these plants and all of the withdrawal fluences were below 1.8x10 1 9 n/cm 2 , which is less* than the fluence range of interest for this program (3x10`9 to 10xl0 9 n/cm 2).*These plants participate in the B&W Master Integrated Reactor Vessel Surveillance Program (MIRVP) [15, 16].*The CRVSP will continue to allow the MIRVP plants to participate in the B&W Master Integrated Reactor Vessel Surveillance Program. Surry Unit 2 and*Turkey Point Unit 4 are the only MIRVP participants to which the CRVSP*makes recommended changes to the plant specific RVSP. The MIRVP does not require Surry Unit 2 to test any additional capsules, so the CRVSP recommendation for Surry Unit 2 to test an additional capsule does not* negatively impact the MIRVP. The MIRVP states that Turkey Point Unit 4 will test capsule X at the end of cycle 27, which is between once and twice the projected 60-year peak RPV fluence. The CRVSP recommends that Turkey*Point Unit 4 test capsule X at the projected 80-year peak RPV fluence, which is between once and twice the projected 60-year peak RPV fluence. Since Turkey Point is the only MIRVP participant that will use the data from capsule X, this*recommended change does not negatively impact the MIRVP.Where changes to existing RVSPs have been recommended as part of this 0optimized, coordinated program, they are identified as bulleted items in the 5"Recommended Program" discussion for each plant.*When changes to a plant's RVSP capsule withdrawal schedule are recommended,*those recommendations are expressed in terms of the plant's peak RPV fluence at*some future time in life. For example, a recommendation may be made to defer capsule withdrawal from a planned date of 2016 to a future time when the Scapsule has attained a fluence equal to that plant's 80 year peak RPV fluence. To implement that recommendation, the plant determines the appropriate outage<6-1 >0 0 0 S 0 (or year) to withdraw the capsule in order to achieve that fluence, based on its 0 current fluence and capacity factor projections and using the same methodology that would be used to. calculate, for example, the appropriate withdrawal date for*its 60 year license renewal capsule.*After recommended changes are identified (bulleted items in the "Recommended Program" section for each plant), a "Discussion" is generally provided that describes the estimated withdrawal date(s) and capsule fluence(s) that would be achieved by implementation of the recommendations.
These estimates are for*coordinated planning purposes only -used by the CRVSP to estimate capsule data availability to fill high fluence data gaps -and are not meant for any other*analysis.
Final determination of the appropriate capsule withdrawal year that*achieves the CRVSP recommendation is the responsibility of the plant, based on data deemed by the plant to be authoritative and appropriate.
For many plants, the statement provided in the "Recommended Program" section may be "No changes are recommended to the current capsule withdrawal plan, test schedule, or related commitments." This statement is intended to*address whether or not a change is recommended in order to obtain the*objectives of the CRVSP. The statement is not intended to discourage any plant from taking an appropriate action to increase the amount of surveillance data or the fluence level of surveillance data if the plant deems such an action to be in its*best interest and compliant with 10 CFR 50 Appendix H [3] requirements.
For example, this report may provide a discussion that consideration was given to asking a plant to move a capsule from the spent fuel pool back into the reactor for further irradiation, but that it was decided not to make that recommendation.
Moving the capsule may be in the plant's best long-term interest, and there is no intent to discourage such an action, even though the CRVSP did not deem it*necessary for the objectives of the CRVSP.0Arkansas Nuclear One Unit 2 0*Material Description
- Six surveillance capsules containing beltline materials fabricated from ASME*SA-533, Grade B, Class 1 (low Cu) and weld flux Linde 91 (low Cu) were*inserted in the reactor prior to initial start-up [19, 20].0Current Program Two of the original six surveillance capsules (W-97 and W-104) have been*removed and tested, [19]. The lead factor of 1.47 for capsule W-104 was calculated using the capsule fluence (2.937x10 1 9 n/cm 2) and the peak RPV at the time of capsule removal (2.001xlO' 9 n/cm 2) [19]. The lead factor for capsule W-284 is assumed to be the same as capsule W-104 based on the symmetry of the*capsule locations
[19]. Arkansas Nuclear One (ANO) Unit 2 received approval*for a 60-year (48 EFPY) license renewal in 2005, which requires a standby capsule be removed at the fluence equivalent to EOL peak RPV fluence of* 5.277x10'9 n/cm 2 [21].<6-2>0 0 0 0 0 S 0 0 Using the capsule lead factor and the linear relationship between EFPY and the peak RPV fluence, the EFPY required for capsule W-284 to reach 5.277x10 9 n/cm2 was calculated to be 29.8. This linear relationship was based on 3.791x10'9* n/cm 2 at 32 EFPY and 5.580x10 9 n/cm 2 at 48 EFPY [19]. Assuming a capacity factor of 0.95 starting in 2001, capsule W-284 should reach the projected fluence*in about 2016.0Table 6-1*ANO Unit 2 Current Withdrawal Schedule [19, 21]0 W-83 830 -- Standby ..~~~~~~~W -97 970 -1.[ (1_98_2) 1........

- Beaver Valley Unit I S Material Description
- Eight surveillance capsules containing beltline materials fabricated from ASME*SA-533, Grade B Class 1 (high Cu) and Linde 1092 flux (high Cu) were inserted in the reactor vessel prior to initial start-up [22].5Current Program*Half of the original eight surveillance capsules (V, U, W and Y) have been*removed and tested, Table 6-2 [22]. Beaver Valley Unit 1 (BV1) was approved for a 60-year license renewal in 2009 [23]. Per utility input, the projected 60-year (50 EFPY) peak RPV fluence is 5.58x10 1 9 n/cm 2.Capsule T was moved to 650 at*the end of cycle 10 (10.8 EFPY). Capsule Z was moved to 165' at the end of*cycle 10 (10.8 EFPY). These capsules were moved to increase the flux, thus producing higher fluence specimens.
Based on utility input, capsule X is planned* to be withdrawn at a fluence of 5.01xl0 1 9 n/cm 2 in 2013 (26.5 EFPY).Per utility input, capsule Z will be withdrawn after reaching the projected 60-*year (50 EFPY) peak RPV fluence, which is currently estimated to be at 36.6*EFPY.

Supplemental capsule A should be removed during the first scheduled outage after the capsule is estimated to attain a fluence equal to the BV1 projected 80-year peak RPV fluence. At a minimum, the BV1 capsule Y Linde 1092 weld metal contained in capsule A should then be tested.Discussion BV2 Capsule A: The following information was provided by the utility for the purpose of developing the CRVSP. The projected 80-year (68 EFPY) peak RPV fluence for BV1 is 7.62x10 1 9 n/cm 2.Capsule A will reach a fluence of 7.67x10'9 n/cm 2 in 2025 (32 EFPY). The previously irradiated material from BV1 capsule Y contained in capsule A will have an approximate cumulative fluence of 9.72x10 1 9 n/cm 2 in 2025. The projections resulting from these estimations are shown in the table below.Testing additional BV1 surveillance material is not required for the BV1 60-year license, but it could support a potential BV1 license renewal to 80 years. Testing the BV1 capsule Y Linde 1092 weld metal contained in capsule A will help fill high fluence data gaps in the Linde 1092 (high Cu) material group, as shown in Figure 4-13.<6-5>
S 0 S 0* BV2 Capsule Y:* 'As noted above, plant personnel provided input during development of the* CRVSP that testing of Capsule Y is already planned by the plant. Therefore,* testing Capsule Y is not identified as a recommended change because it is not a change from the current program. However, testing Capsule Y makes a valuable* contribution to the CRVSP and warrants additional discussion.
Although testing* an additional capsule is not required for the BV2 60-year license, testing capsule Y or Z as currently planned will help fill high fluence data gaps in the SA-533* (low Cu) and Linde 91 (low Cu) material groups, as shown in Figure 4-1 and* Figure 4-9.* Table 6-4* Beaver Valley Unit 2 Estimated Results of Recommended Changes to Withdrawal Schedule.........

- Six surveillance capsules containing beitline materials fabricated from ASME* SA-508 Class 3 (low Cu) and Linde 80 flux (low Cu) were inserted in the reactor* prior to initial start-up [25].0 Current Program Half of the original surveillance capsules (U, X and W) have been removed and* tested, Table 6-5 [25].

- The fluence for capsules Z, V and Y were estimated using the capsules' lead factors and the linear relationship between the reported peak RPV fluences and their corresponding EFPY values. This linear relationship was based on a fluence* of 1.97x10 1 9 n/cm 2 at 32 EFPY, 2.94x10'9 n/cm 2 at 48 EFPY and 3.3x10 9 n/cm 2* at 54 EFPY [25].6 0, 0 <6-6>0 0 0 S J 0 0 0* Table 6-5 Braidwood Unit 1 Current Withdrawal Schedule [25, 26]0 0 U 58.50 4.37 1 1.10 3.87x10 1 8 X 238.50 4.23 4 4.234 1.24x10'9* W 121.50 4.20 7 7.61 2.09x10 9 (a)Z 301.50 4.20 Storage 12.01 3.21x10'9 (b)V 61.00 3.92 Storage 17.69 4.34x 0 1 9 (c)..Y 241.0.. 3.92 Storage 1 2.01 2.9g19 (a) A x .....

Discussion The value of reinserting Capsule V and continuing irradiation to achieve a higher 0fluence was assessed, but that action is not recommended because the benefit to the plant or the PWR surveillance database (SDB) is low. The remaining capsules contain low copper SA-508 base metal and low copper Linde 80 weld metal. High fluence surveillance data will be well represented in the low copper* SA-508 category above the projected 2x60-year peak RPV fluence of 6.6x10 9 n/cm 2 without the Capsule V data. The low copper Linde 80 weld metal is unique to Braidwood and Byron units. Therefore, reinsertion of Capsule V for*further irradiation provides minimal benefit to the PWR fleet SDB.Furthermore, the data will be available when the capsule is tested for license renewal, if the plant applies for a renewed license. Therefore, there is no need for 0the CRVSP to recommend any change to the Braidwood 1 RVSP. When the need develops in the future to test a capsule, however, it is suggested that preferential consideration be given to testing the capsule with highest fluence.0 0 0 0 0 0 0 0~<6-7 *0 0 0 0 0 0 0* Braidwood Unit 2*Material Description 0 Six surveillance capsules containing beltline materials fabricated from ASME SA-508 Class 3 (low Cu) and Linde 80 flux (low Cu) were inserted in the reactor*prior to initial start-up [27].0Current Program* Half of the original surveillance capsules (U, X and W) have been removed and tested while capsules Z and Y have been removed without testing, Table 6-6[26].

Three capsules (S, V and Y) also contain Linde 1092 flux (high Cu) in addition to the ASME SA-533 Grade B Class 1 (low Cu) [49].Replacement capsules (A, B, C and D) were inserted after cycle five [50] and contain ASME SA-533 Grade B Class 1 (high Cu) and Linde 1092 flux (high*Cu) Charpy specimens.
In addition, Capsules B, C and D contain Charpy*specimens supplied by EPRI including Linde 124, Linde 0091 and Linde 80 flux. Capsules B and D also CVN weld specimens that had been irradiated in*Capsule S.0 Current Program 5Three of the twelve surveillance capsules (S, Y and V) have been removed and tested, Table 6-21 [51]. Capsules A, B, C and D were inserted at the end of cycle five after 5.86 EFPY of plant operation.

Capsule B should be removed at the last outage before the capsule is estimated to receive a neutron fluence equal to two times the peak RPV neutron fluence at the end of the period of extended operation.
Capsule B should then be tested.Discussion For the purpose of developing the CRVSP, the projected 2x60-year peak RPV fluence and year of withdrawal were estimated as follows: The removal fluence value of 4.12x10 1 9 n/cm 2 is twice the 60-year (54 EFPY) RPV peak fluence of 2.06x10 1 9 n/cm 2 [49]. Using the capsule lead factor and linear relationship between the reported peak RPV fluences and their corresponding EFPY values, the EFPY required for capsule B to go from 3.23x10 1 9 n/cm 2 to 4.12x10'9 n/cm 2 was calculated to be 7 EFPY. Assuming a 0.95 capacity factor starting in 2002 and the projected removal EFPY of 30.2, the capsule will reach the specified fluence in about 2018. The projections resulting from these estimations are shown in the table below. The plant is responsible for formal determination of the planned withdrawal year, based on the latest RPV fluence data.< 6-23 >

Fort Calhoun Unit 1 Material Description Six surveillance capsules containing beltline materials fabricated from ASME SA-533 Grade B Class 1 (low Cu) and weld flux Linde 1092 (high Cu) were inserted in the reactor prior to initial start-up [55].Three supplemental capsules (W-225S, W-265S and W-275S) containing materials fabricated from weld flux Linde 1092 (high Cu) were inserted at a later date. Capsules W-225S and W-265S contain Linde 1092 weld heat 305414 while W-275S (installed in 1993) contains weld heats 27204 and 12008/13253
[56].Current Program Three of the original six surveillance capsules (W-225, W-265 and W-275) have been removed and tested, Table 6-26 [57]. Capsule W-275S was inserted at the end of cycle 14 [56]. Fort Calhoun received approval for a 60-year (48 EFPY)license renewal in November 2003. The projected 60-year (48 EFPY) peak RPV fluence is 3.5x10'9 n/cm 2 [58]. Fort Calhoun takes credit for surveillance data irradiated in Mihama Unit 1, Diablo Canyon Unit 1 and Palisades
[57].The capsule lead factors were provided per correspondence with the utility.Per utility input, there are plans to change withdrawal and test of capsule W-275S (which is currently scheduled to be removed and tested at 33.6 EFPY) to 47.2 EFPY (2028) with a fluence of 3.0x10 1 9 n/cm 2.< 6-26 >
S S 0 Capsule W-95 will be removed and tested after 48 EFPY [57]. Using the capsule 0 lead factor and the linear relationship between the peak RPV fluence and the*corresponding EFPY values, the capsule fluence at 48 EFPY was calculated to be* 3.92x10 9 n/cm 2.Assuming a capacity factor of 0.95 starting in 1993, capsule W-95 should reach 3.92x10'9 n/cm 2 in about 2029.0*Table 6-26 Fort Calhoun Current Withdrawal Schedule [55, 57]*W-265 2650 10 5. li 9.0x1 0 1 8 W-275 275' 1.05 14 (1993) _13.6 1.380010 9 0 W-45 450 1.51 Standby -- 5 W-85 850 1.17 Standby ..--* W-95 950 1.17 Planned 48.0 3.92X100"(a)

Capsule W-45 should then be tested.2 Capsule W-95 should remain in the reactor on standby until needed to fulfill*future 10 CFR 50 Appendix H [3] or license renewal requirements.
M Capsule W-275S should be removed at 47.2 EFPY (rather than at 33.6*EFPY) to obtain higher fluence data for the limiting RV welds. [See note in Discussion.]
- I Discussion
- For the purpose of developing the CRVSP, the projected 80-year peak RPV*fluence and year of withdrawal were estimated as follows: The 80-year (67 EFPY) fluence of 4.72x10 9 n/cm 2 was extrapolated from the linear relationship between the peak RPV fluence and the corresponding EFPY values. The 67*EFPY value was determined by assuming a 0.95 capacity factor starting after 60 years of operation.
Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and their corresponding EFPY values,* capsule W-45 should reach the specified fluence at 42 EFPY, which will occur in*about 2022. The projections resulting from these estimations are shown in the<6-27 )0 0 0 0 0 0 0 table below. The plant is responsible for formal determination of the planned 0year of withdrawal, based on latest vessel fluence data.Note: The change in withdrawal schedule for W-275S from 33.6 EFPY to 47.2 0EFPY is not a recommendation from the CRVSP and is not required to obtainthe objectives of the CRVSP; it was added to the list of recommended changes at*the request of the plant.*Table 6.27 Fort Calhoun Estimated Results of Recommended Changes and Plant's Changes to Withdrawal Schedule 00 Capule Loctio Led simateiReova MEstim ted-0.Factr Reova (EFY) luence 0* W-45 450 1.51 ...2022 ... .40 4...!7200°'9(a)

Discussion 9* For the purpose of developing the CRVSP, the projected 80-year peak RPV fluence and withdrawal year were estimated as follows: The projected EFPY for 0 the 80-year license was determined using a conservative capacity factor of 0.95.* Based on the 32 EFPY fluence of 3.37x10" 9 n/cm 2 and the 60-year (54 EFPY)fluence of 5.162x10 1 9 n/cm 2 [93], the 80-year (73 EFPY) peak RPV fluence was determined by extrapolation to be 6.7x101 9 n/cm 2.For the purpose of this O discussion, it is assumed that Capsule T will be withdrawn, although the plant* may choose to withdraw Capsule N. Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and their corresponding O EFPY values, the EFPY required for capsule T to reach 6.7x10 1 9 n/cm 2 was 9 calculated to be 34.1. Assuming a 0.95 capacity factor starting in 1996 and the projected removal EFPY of 34.1, capsule T should reach the specified fluence in*about 2013.

- For the purpose of developing the CRVSP, the projected 40-year peak RPV*fluence and year of withdrawal were estimated as follows: The projected 40-year (32 EFPY) peak RPV fluence is 4.19x101 9 n/cm 2 [106]. Using the capsule lead factor and the linear relationship between the reported peak RPV fluences and*their corresponding EFPY values, the EFPY required for capsule 830 to reach 4.19x101 9 n/cm 2 was extrapolated to be 26.5 EFPY. This linear relationship is based on 2.01x10'9 n/cm 2 at 14.93 EFPY and 4.19x10 1 9 n/cm 2 at 32 EFPY*[106].

0 0 DiscussionFor the purpose of developing the CRVSP, the projected 2x60-year peak RPV fluence and year of withdrawal were estimated as follows: The projected EFPY for the 60-year license was determined using a conservative capacity factor of 0.95. Based on the 60-year (54 EFPY) fluence of 3.01xl0 1 9 n/cm 2 , twice the 60-* year (54 EFPY) peak RPV fluence was determined to be 6.02x10'9 n/cm 2.Using the capsule lead factor and the linear relationship between the reported peak*RPV fluences and their corresponding EFPY values, the EFPY required for capsule V to reach 6.02x10'9 n/cm 2 was calculated to be 25.7. Assuming a 0.95 capacity factor starting in 2006 and the projected removal EFPY of 25.7, capsule V should reach the specified fluence in about 2023.

0 NEI 03-08 Implementation Protocol This program is a 'work product' of the EPRI MRP, an 'Issue Program (IP)' as defined in NEI 03-08 [5]. Addendum D to NEI 03-08, Implementation Protocol, defines the processes and expectations for implementing industry*guidance issued under the Materials Initiative, and requires that IPs identify the*specific implementation category for 'requirements' identified guideline-type work products.*The three implementation categories described in NEI 03-08 are as follows:* Mandatory-to be implemented at all plants where applicable;
- Needed -to be implemented wherever possible, but alternative approaches
- are acceptable; and* Good Practice -implementation is expected to provide significant operational and reliability benefits, but the extent of use is at the discretion of*the individual utility.*The CRVSP recommended changes detailed in Section 6 of this report have 0been designated as "Needed" requirements, as explained below. A failure to meet 9a Needed requirement is a deviation from the guidelines and a written justification for the deviation must be prepared and approved as described inAppendix B to NEI 03-08 [5]. A copy of the deviation is sent to the MRP so*that improvements to the guidelines can be developed.
0Implementation of this guidance as a Needed requirement is justified because the*ability of the CRVSP to achieve the objectives of obtaining higher fluence PWR surveillance data is dependent on all plants with recommended changes implementing those recommendations.
It was discussed earlier in this report that*the paucity of high fluence PWR data without the CRVSP is likely to result in an embrittlement trend correlation based in large part on test reactor data at<7-1 >0 0 0 0
- 0 fluences above 3x10 1 9 n/cm 2; such an ETC could result in significantly increased* RPV embrittlement predictions because test reactor data typically exhibits higher rates of embrittlement.
This in turn could have significant financial impact on the industry, ranging from increased startup/shutdown times and costs (and regulatory action) to the possible need for some plants to mitigate RPV 0embrittlement resulting from application of embrittlement correlations that are not representative of power reactor trends. The Yankee Rowe experience clearly demonstrated the ability of RPV embrittlement issues to shorten the useful*financial life of a unit. Thus, the issue fulfills either of the following conditions
- for implementation under the "Needed" category:* "Element addresses a material degradation mechanism
[neutron embrittlement]
that has significant financial impact on the entire industry, especially where failure at one plant could affect many other plants.M A consensus of the responsible materials IP believes the element should be designated
- as 'Needed"." 0Coordinated Surveillance Program Requirement
- Needed: Following issuance ofMRP-326, Rev. 0, each commercial US. PWR unit for which a change to its reactor vessel surveillance program has been recommended in Section 6 shall Submit a request to the NRC to revise the plant's surveillance capsule program and/or schedule as required to implement the recommendation(s).
The changes covered by this requirement are presented as bulleted items in the 'Recommended Program" section for each plant in Section 6; plants with no bulleted recommendations require no action. When submission ofprogram change request is* required, the submission shall be made per the following schedule.-
-If the change affects a capsule withdrawal/test which is scheduled before January 1, 2014, the request should be submitted to the NRC no later than ten* months following the issuance ofMRP-326, Rev. 0.-If the change affects a capsule withdrawal/test which is scheduled after January 1, 2014, the request should be submitted to the NRC no earlier than ten months nor later than 18 months after issuance ofMRP-326, Rev. 0.0 The phased submission of RVSP change requests to the NRC will make the flow of requests arrive in general order of calendar urgency and will permit plants with*near-term needs to receive priority review.*An optional template for use in generating the letter request to the NRC is*provided in Appendix B of this document.
The template provides a format that*will demonstrate the plant's continued compliance with 10 CFR 50, Appendix H, after implementation of the recommended changes.0 0 0~<7-2>*0 0 0 0 0 0 0 0 0* Section 8: References

The proposed reactor vessel surveillance capsule removal schedule was developed to implement recommendations for [plant name] in MRP-326, CoordinatedPWR Reactor Vessel*Surveillance Program (CR VSP) Guidelines.
MRP-326 addresses the need for reactor vessel property data at fluences representative of 60 years of operation and beyond for [Plant Name] and the industry.
The requested change to the Appendix H program for [Plant Name] satisfies the requirements of 10 CFR 50, Appendix H and ASTM E-185-82, "Standard Practice for Conducting Surveillance Tests for Light-Water Cooled Nuclear Power Reactor Vessels", dated July 1, 1982, and is consistent with the guidance of*NUREG-1801, Rev. 2, Generic Aging Lessons Learned 0Approval of this proposed change is requested no later than [date].0Summary of Commitments This letter contains no new commitments and no revisions to existing commitments.

BackgroundAppendix H to 10 CFR Part 50 describes reactor vessel material surveillance program requirements.
Paragraph (III)(B)(3) of this Appendix states that a proposed material withdrawal schedule must be 0 submitted with a technical justification per 10 CFR 50.4, and approved prior to implementation.
0 Industry has developed a Coordinated PWR Reactor Vessel Surveillance Program (CRVSP), which is* documented in MRP-326, Coordinated PWR Reactor Vessel Surveillance Program (CR VSP) Guidelines.
The purpose of the CRVSP is to increase the fluence levels of future surveillance capsules at withdrawal while*maintaining compliant with 10 CFR 50 Appendix H and consistent with the guidance of NUREG-1801, Rev. 2, GALL Report. The CRVSP will help generate high fluence PWR surveillance data in support of extended life operations.
The proposed withdrawal schedule satisfies the requirements of American Society for Testing and*Materials (ASTM) E 185-xx, the version that was current at the time the reactor vessel surveillance
- program was designed.Table (1) shows the currently approved withdrawal schedule for [plant name] reactor vessel surveillance
- capsules (Updated Final Safety Analysis Report Table x-xx).0 II. Proposed Revision 0 Table (2) provides the proposed revision to the reactor vessel surveillance capsule withdrawal schedule for[plant name]. The revised schedule is based on the recommendations for [plant name] in MRP-326, and reflects updated fluence information from the surveillance capsule removed in [year] with appropriate adjustment made for fuels loaded in subsequent cycles. As shown below in Section III, the proposed withdrawal schedule satisfies the requirements of ASTM E 185-xx, the version that was current at the time the reactor vessels were designed.
Therefore, the withdrawal schedule satisfies the requirements of*Appendix H to 10 CFR Part 50.0 III. Justification 0The [plant name] reactor vessel was designed to the [year] through [idenity of applicable addenda]*Addenda, edition of the American Society of Mechanical Engineers Code. American Society for Testing and Materials E 185-xx was the current standard when the surveillance program was designed.
As stated in the [Plant name] Updated Final Safety Analysis Report, the reactor vessel surveillance program meets*the requirements of ASTM E 185-xx.The guidance provided in ASTM E 185-82 is consistent with, but more specific than, the guidance*provided in earlier editions, including ASTM E 185-xx to which the [plant name] reactor vessel*surveillance program is required to conform. Therefore, compliance with the ASTM E185-82 withdrawal schedule guidance ensures compliance with ASTM E 185-xx withdrawal schedule guidance.
ASTM E 0 0 0 0 0 0 0 185-82 provides a withdrawal schedule in terms of years of operation but also provides the option to 0 develop a schedule tied to target fluences accumulated in the vessel. As in the case of the currently approved withdrawal schedule, the proposed withdrawal schedule follows the guidance that ties the withdrawal schedule to vessel fluence targets.0 This request proposes to revise the reactor vessel surveillance capsule withdrawal schedule to [detail the specific change as recommended byMRP-326].
A detailed explanation of the change for [plant name] is provided in MRP-326.* The [capsule name] capsule meets the requirements of ASTM E 185-82 to withdraw the third capsule at a time when the accumulated neutron fluence on the capsule corresponds to the approximate end of life peak fluence at the reactor vessel 1 T location.
As noted on Table (2), we would withdraw the [capsule name] capsule during the [year or RFO number] refueling outage and designate the [capsule name] capsule as the standby capsule [if applicable].
This proposed change meets the requirements of Appendix H to 10 CFR Part 50.* If applicable:
[Plant name] received approval of license renewal in [year]. The [plant name] license renewal application (LRA) referenced GALL Revision 1, and Capsule [capsule name] was identified as the capsule to be tested to meet the recommendations of GALL Rev. 1. GALL Rev. 1 recommends that the plant"...withdraws one capsule at an outage in which the capsule receives a neutron fluence equivalent to the 60-year fluence...." As aresult, the current capsule withdrawal schedule is based on withdrawing Capsule[capsule name] at Refueling Outage (RFO)-xx.
NUREG-1801, Rev. 2 (GALL Report) recommends that 0* e "The plant-specific or integrated surveillance program shall have at least one capsule with a projected neutron fluence equal to or exceeding the 60-year peak reactor vessel wall neutron 0 fluence prior to the end of the period of extended operation.
The program withdraws one capsule at an outage in which the capsule receives a neutron fluence of between one and two times the peak reactor vessel wall neutron fluence at the end of the period of extended operation and tests* the capsule in accordance with the requirements of ASTM E 185-82.""Plant-specific and fleet operating experience should be considered in determining the withdrawal schedule for all capsules..." 0 The proposed withdrawal date for Capsule [capsule name] meets both of these recommendations.
The operating experience of both [Plant name] and the U.S. PWR fleet were considered in the development of the revised capsule withdrawal schedule, as discussed in MRP-326. The capsule fluence at the proposed 0 withdrawal date will meet the guidance that the license renewal capsule should achieve a fluence between one and two times the peak reactor vessel wall neutron fluence at the end of the period of extended* operation.
