INSERT 8 DOC M11 5.5.18 Setpoint Control Program 25 16 This program shall establish the requirements for ensuring that setpoints for automatic protective devices are initially within and remain within the technical assumptions of specification requirements. This program provides a means for processing the applicable safety analyses, changes to instrumentation setpoints and identifies setpoint methodologies to shall ensure instrumentation will function as required. The program also ensures that testing of automatic protective devices related to variables having significant safety functions as delineated by 10 CFR 50.36(c)(1)(ii)(A) verify that instrumentation will function as required.

- 6. LCO 3.3.8, "Fuel Building Air Cleanup System (FBACS) Actuation Instrumentation;"
- b. The program shall require the Nominal Trip Setpoint (NTSP), Allowable Value (AV), As-Found Tolerance (AFT), and As-Left Tolerance (ALT) (as applicable) of the Functions described in Paragraph a. are calculated using the NRC approved setpoint methodology, as listed below. In addition, the program shall contain the value of the NTSP, AV, AFT, or ALT (as applicable) for each Function described in paragraph a. and shall identify the setpoint methodology used to calculate these values.

REVIEWERS NOTE --------------------------------------
A license amendment request to implement a Setpoint Control Program must list the instrument functions to which the program requirements of paragraph
- d. will be applied. Paragraph d shall apply to all Functions in the Reactor Trip System and Engineered Safety Feature Actuation System specifications unless one or more of the following exclusions apply:
- 1. Manual actuation circuits, automatic actuation logic circuits or to instrument functions that derive input from contacts which have no associated sensor or adjustable device, e.g., limit switches, breaker position switches, manual actuation switches, float switches, proximity detectors, etc. are excluded. In addition, those permissives and interlocks that derive input from a sensor or adjustable device that is tested as part of another TS function are excluded.
- 2. Settings associated with safety relief valves are excluded. The 15 performance of these components is already controlled (i.e., trended with as-left and as-found limits) under the ASME Code for Operation and Maintenance of Nuclear Power Plants testing program.
- 3. Functions and Surveillance Requirements which test only digital components are excluded. There is no expected change in result between SR performances for these components. Where separate as-left and as-found tolerance is established for digital component SRs, the requirements would apply.

DOC M11 d. The program shall identify the Functions described in Paragraph a. that are automatic protective devices related to variables having significant safety functions as delineated by 10 CFR 50.36(c)(1)(ii)(A). The NTSP of these Functions are Limiting Safety System Settings. These Functions shall be demonstrated to be functioning as required by applying the following requirements during CHANNEL CALIBRATIONS, CHANNEL OPERATIONAL TESTS, and TRIP ACTUATING DEVICE OPERATIONAL TESTS that verify the NTSP.
- 1. The as-found value of the instrument channel trip setting shall be compared with the previous as-left value or the specified NTSP.
- 2. If the as-found value of the instrument channel trip setting differs from the previous as-left value or the specified NTSP by more than the pre-defined test acceptance criteria band (i.e., the specified AFT), then the instrument channel shall be evaluated before declaring the SR met and returning the instrument channel to service. This condition shall be entered in the plant corrective action program.
- 3. If the as-found value of the instrument channel trip setting is less conservative than the specified AV, then the SR is not met and the instrument channel shall be immediately declared inoperable.
- 4. The instrument channel setpoint shall be reset to a value that is within the as-left tolerance around the NTSP at the completion of the surveillance (setpoints test; otherwise, the channel is inoperable. Setpoints may be more conservative than the NTSP provided that the as-found and as-left tolerances apply to the actual setpoint used to confirm channel performance.

Response
3/1/2010 3:30 PM Date/Time Closure Statement Response KPS has reviewed the errata to TSTF-493, Rev. 4 and determined that the Statement draft markup attached to the previous KPS response to KAB-069 did not include the NRC reviewer's requested change. In lieu of the NRC reviewer recommended wording for ITS 5.5.16.e to include the program name from what is specified in the originally submitted ITS 5.5.16.b.1 (i.e., Technical Report EE-0116), the TSTF errata allows the name of a document incorporated by reference into the facility FSAR. KPS will specify the Technical Requirements Manual (TRM) as the document. The TRM is currently referenced in the KPS USAR. Using the TRM as the reference document is also consistent with many other CTS requirements that are being relocated to the TRM as part of the ITS conversion. A draft markup regarding these changes is attached, and supersedes the previous draft markup. Changes from the previous markup are identified in green (see pages 2 and 3 of the attachment). These changes will be reflected in the supplement to this section of the ITS conversion amendment.

- 1. Manual actuation circuits, automatic actuation logic circuits or to instrument functions that derive input from contacts which have no associated sensor or adjustable device, e.g., limit switches, breaker position switches, manual actuation switches, float switches, proximity detectors, etc. are excluded. In addition, those permissives and interlocks that derive input from a sensor or adjustable device that is tested as part of another TS function are excluded.
- 2. Settings associated with safety relief valves are excluded. The 15 performance of these components is already controlled (i.e., trended with as-left and as-found limits) under the ASME Code for Operation and Maintenance of Nuclear Power Plants testing program.
- 3. Functions and Surveillance Requirements which test only digital components are excluded. There is no expected change in result between SR performances for these components. Where separate as-left and as-found tolerance is established for digital component SRs, the requirements would apply.

- 1. Kewaunee Power Station (KPS) is a single unit site. Therefore, the allowance provided by this reviewers Note is not needed and has not been adopted in the KPS ITS.
- 2. The ISTS contains bracketed information and/or values that are generic to all Westinghouse vintage plants. The brackets are removed and the proper plant specific information/value is provided. This is acceptable since the generic specific information/value is revised to reflect the current plant design.
- 3. Changed the ISTS 5.6.2 submittal date to be consistent with the current KPS submittal date in CTS 6.9.b.2.
- 4. ISTS 5.6.4, "Reactor Coolant System (RCS) PRESSURE AND TEMPERATURE LIMITS REPORT (PTLR)," is not adopted in the ITS. CTS Figures TS 3.1-1 and TS 3.1-2, which provide Reactor Coolant System heatup and cooldown limitations, respectively, were adopted in ITS 3.4.3, "RCS Pressure and Temperature (P/T) Limits." Subsequent Specifications are renumbered accordingly.
- 5. The bracketed ISTS 5.6.6, "Tendon Surveillance Report," is not included in the Kewaunee Power Station (KPS) ITS since KPS does not have pre-stressed concrete tendons. Subsequent Specifications are renumbered accordingly.
- 6. The punctuation corrections have been made consistent with the Writer's Guide for the Improved Standard Technical Specifications, TSTF-GG-05-01, Section 5.1.3.
- 7. ISTS 5.5.3, "Post Accident Sampling," and ISTS 5.5.6, "Pre-Stressed Concrete Containment Tendon Surveillance Program," are not included in the KPS ITS.
As a result, subsequent programs in ITS Section 5.5 have been renumbered and Specification 5.5.9 is now 5.5.7.
- 8. Changes have been made due to changes made to another Specification. Condition F in ITS 3.3.3 has not been adopted, thus it is being deleted in ITS 5.6.4.

Notification NRC/LICENSEE Supervision Victor Cusumano Jerry Jones Bryan Kays Ray Schiele Added By Robert Hanley Date Added 11/16/2009 4:14 PM Modified By Date Modified Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 27 of 169 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=801 06/07/2010
Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 28 of 169 DISCUSSION OF CHANGES ITS 5.2, ORGANIZATION 10 CFR 50.54(m)(2)(iv). This change is designated as administrative because it does not result in technical changes to the CTS.
A03 CTS 6.2.d states that changes not affecting safety may be made to the off-site and facility organizations and that such changes that are described in the Technical Specifications shall be reported to the NRC in the form of an application for license amendment within 60 days of the implementation of the change. This allowance is not being maintained in the ITS. This changes the CTS by deleting an allowance to make certain changes to the CTS prior to actually receiving a Technical Specification change.
The purpose of CTS 6.2.d was to allow Dominion Energy Kewaunee (DEK) to make changes to the unit staff organization, such as title changes, without waiting for prior NRC approval. However, License Amendment 193 (ADAMS Accession No. ML072880065) changed the CTS by deleting all plant specific titles and replacing them with generic titles, and specifying that the plant specific titles are in administrative documents. Furthermore, as stated in CTS 6.2.a and b, the off-site and facility organization is described in the quality assurance program. Thus, with the approval of License Amendment 193, this CTS 6.2.d allowance is unnecessary - no changes that do not affect safety are necessary, since all plant-specific titles have been removed from the CTS. Therefore, this change is acceptable and is considered administrative since KPS does not believe the current CTS 6.2.d allowance can be used at this time.
A04 CTS 6.3.b states that "The shift technical advisor shall have a bachelor's degree or equivalent in a scientific or engineering discipline with specific training in the 2
design of the Kewaunee Plant and plant transients. ITS 5.5.2.e states that "An individual shall provide advisory technical support to the unit operations shift crew in the areas of thermal hydraulics, reactor engineering, and plant analysis with regard to the safe operation of the unit. This individual shall meet the qualifications specified by the Commission Policy Statement on Engineering Expertise on Shift." This changes the CTS by referencing the Commission Policy Statement on Engineering Expertise on Shift for qualification requirements instead of specific qualifications.
The purpose of 6.3.b requirements is to specify the minimum qualification requirements for the shift technical advisor. This change is acceptable because the qualification requirements included in the Commission Policy Statement on Engineering Expertise on Shift (Generic Letter 86-04, dated February 13, 1986) encompass the current shift technical advisor qualification requirements. This change is designated as administrative because it does not result in a technical change to the CTS.
MORE RESTRICTIVE CHANGES M01 CTS 6.1.a describes that the plant manager is responsible for overall plant operation. CTS 6.2.a states that the off-site organization for plant management and technical support shall be as described in the quality assurance manual.
CTS 6.2.b states that the plant organization shall be as described in the quality assurance program. ITS 5.2.1 states:

Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 29 of 169 DISCUSSION OF CHANGES ITS 5.2, ORGANIZATION RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES None LESS RESTRICTIVE CHANGES L01 (Category 1 - Relaxation of LCO Requirements) CTS 6.2.b.1.B requires two licensed reactor operators to be on duty at all times as part of the shift complement. This requirement is being deleted from the Technical Specification since it is duplicative of 10 CFR 50.54(m)(2)(i). This is discussed in DOC A02.
However, 10 CFR 50.54(m)(2)(i) only requires one licensed Operator to be on duty when in MODE 5 or 6 or defueled. This changes the CTS by only requiring one licensed Operator to be on duty when in MODE 5 or 6 or defueled.
The purpose of CTS 6.2.b.1.B is to ensure the proper number of licensed Operators are on duty as required by NRC regulations. This change is acceptable since the NRC has already approved, as documented in 10 CFR 50.54(m)(2)(i), the minimum number of Licensed Operators required to be on duty in MODES 5 and 6 and defuled. This change is designated as a less restrictive change since the LCO requirements are less restrictive than are currently required in the CTS.
L02 (Category 1 - Relaxation of LCO Requirements) CTS 6.2.b.1.E requires one radiation technologist to be on duty at all times as part of the shift complement.
2 ITS 5.5.2.c only requires one radiation technologist to be on duty when there is fuel in the reactor vessel. This changes the CTS by not requiring a radiation technologist to be on duty when the reactor is defueled.
The purpose of CTS 6.2.b.1.E is to ensure the proper number of radiation technologists are duty when required. This change is acceptable since the NRC has already approved, as documented in ISTS NUREG-1431, Rev. 3.0 (as well as the other four ISTS NUREGs), allowing no radiation technologists to be on duty when the reactor is defueled. This change is designated as a less restrictive change since the LCO requirements are less restrictive in the ITS than in the CTS.
L03 (Category 1 - Relaxation of LCO Requirement) CTS 6.2.b.7 states that "When the reactor is above the COLD SHUTDOWN condition, a qualified shift technical advisor shall be within 10 minutes of the control room." ITS 5.2.2.e requires the shift technical advisor to be on duty when the unit is in MODE 1, 2, 3, or 4, but does not require the individual to be within 10 minutes of the control room. This changes the CTS by deleting the requirement that the shift technical advisor be within 10 minutes of the control room.

- 1. The ISTS contains bracketed information and/or values that are generic to all Westinghouse vintage plants. The brackets are removed and the proper plant specific information/value is provided. This is acceptable since the generic specific information/value is revised to reflect the current Technical Specifications.
- 2. CTS 6.2.c allows the plant-specific titles of those personnel fulfilling the responsibilities of the positions delineated in the Technical Specifications to be maintained in appropriate plant documents, in lieu of the ISTS requirement that they be in the FSAR/QA Plan. This allowance was approved by the NRC as part of License Amendment 193, dated 10/31/07 (ADAMS Accession No. ML072880065). Therefore, ISTS 5.2.1.a has been changed to reflect this allowance.
- 3. Kewaunee Power Station includes only one unit. Therefore, the words in ITS 5.2.2.a have been modified to reflect a single unit site.
- 4. The Reviewers Note has been deleted. This information is for the NRC reviewer to be keyed into what is needed to meet this requirement. This is not meant to be retained in the final version of the plant specific submittal.
- 5. Typographical error corrected.
- 6. ITS 5.2.2.b has been revised to allow additional time for the shift crew composition to be below the minimum requirements of 10 CFR 50.54 "when severe weather conditions exist." ITS 5.2.2.c has been revised to allow additional time for a vacant radiation protection technician when severe weather conditions exits. This change is consistent with current Kewaunee Power Station (KPS) licensing requirements.
- 7. The generic positions have been used. Also, the terms in 10 CFR 55.4 and 10 CFR 50.54(m) are "Senior Operator" and "Operator," not "Senior Reactor Operator" and "Reactor Operator."

Requested NRC In TS Section 5.5.10 "Explosive Gas and Storage Tank Radioactivity Question Monitoring Program" (VOL 16 Page 95 of 167) you have chosen to delete the ISTS paragraph stating the methodology used to determine the quantities of radioactive gasses and liquid radwaste materials. While the methodology cited in that paragraph is bracketed, the paragraph itself is not.
Please explain how, without a defined methodology, you ensure that this determination provides accurate and reliable results. As you state in DOC M07, your CTS does not have this program. Since there is no current method in use to retain from CTS, please describe the methodology you plan to use, and the basis for not including it in the program description.
In JFD16 you justify the deletion by stating that the program details are described in ITS 5.5.10 parts a, b, and c. These parts do not define a methodology.

1/29/2010 2:25 PM Date/Time Closure Statement Response The current methodology used at Kewaunee Power Station is the Statement methodology described in the bracketed ISTS paragraph. This methodology is currently under KPS control; it is not in the CTS. The ITS submittal did not include this information for that reason, and this same reason has been previously accepted by the NRC during a recent ITS conversion (Davis-Besse, NRC SER dated November 20, 2008).
However, after further review, Kewaunee Power Station (KPS) will agree to put the methodology into the ITS, since it is not believed that the methodology will change in the near future.

Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 35 of 169 JUSTIFICATION FOR DEVIATIONS ITS 5.5, PROGRAMS AND MANUALS final version of the plant specific submittal. Therefore, the Reviewer's Note has been deleted.
- 16. The program details of the Explosive Gas and Storage Tank Radioactivity Monitoring Program are described in ISTS 5.5.12 (ITS 5.5.10) part a, b, and c.
Therefore, the sentence in the introductory paragraph that specifies a method to Not used. determine the explosive gas and storage tank radioactivity is not necessary.
Additionally, this change is consistent with the requirements in ODCM Sections 3/4.3 and 3/4.4.
- 17. ISTS 5.5.13.c requires the total particulate concentration of the fuel oil to be tested every 31 days. The current test frequency at KPS is 92 days (per plant procedures). ITS 5.5.11.c has been changed to be consistent with current KPS practices. KPS has reviewed the maintenance history of this test and determined that the proposed 92 day Frequency is sufficient to ensure total particulates stays within the new ITS 5.5.11.c limit of 10 mg/l. In addition, the KPS diesel storage tanks are outdoor tanks, subject to the weather. Thus, minimizing the number of times the tanks must be opened to obtain fuel oil samples will also benefit keeping snow, rain water, and other contaminants out of the storage tanks.
- 18. Changes are made to the ISTS which reflect the plant specific nomenclature.
- 19. Kewaunee Power Station (KPS) complies with Option B of 10 CFR 50, Appendix J. Therefore, the ISTS 5.5.16 Option A and combined Option A and B provisions have been deleted.
- 20. ISTS 5.5.16.a (ITS 5.5.14.a) contains exceptions to Regulatory Guide (RG) 1.163. The KPS Containment Leak Rate Testing Program does not take any exceptions to the RG 1.163 requirements. Therefore, these exceptions are deleted.
- 21. ISTS 5.5.16.b contains a statement with a bracketed value for the containment design pressure. The containment design pressure limit specified in ISTS 5.5.16.b has not been included because it currently does not exist in the KPS CTS, and because this limit does not provide any useful input to the Containment Leakage Rate Testing Program. Pa is the test pressure and thus is included in the ITS.
- 22. KPS does not include a separate overall air lock leakage limit; it is only included as part of the combined Types B and C leakage limit (0.60 La). Therefore, ISTS 5.5.16.d.2.a) has not been included. Due to this, there is no reason to include the requirements of ISTS 5.5.16.d.2.b) separate from ISTS 5.5.16.d.2. Thus it has been combined into ISTS 5.5.16.d.2. Furthermore, ISTS 5.5.16.d.2.b) states, in part, the air lock acceptance criteria for each door. The CTS 6.20.c states, in part, the air lock acceptance criteria for each air lock door seal. ITS 5.5.14.d.2) is written to address each air lock door seal. This is acceptable since the ITS is edited to reflect the text in the CTS and for clarification. Lastly, ISTS 5.5.16.d.2.b) (ITS 5.5.14.d) contains a bracketed value for the air lock door seal containment leakage rate acceptance criteria and the pressure to which each door seal is tested.

Requested NRC In VOL 16 Page 100 of 167 you delete 5.5.14.f under Containment Question Leakage Rate Testing Program. This section reads: "Nothing in these Technical Specifications shall be construed to modify the testing Frequencies required by 10 CFR 50, Appendix J."
The justification for this deletion is in your JFD 23 and reads: "This phrase is not consistent with the allowances in ISTS 5.5.16.a (ITS 5.5.14.a), which states that the program shall be in accordance with the guidelines contained in Regulatory Guide 1.163, "Performance-Based Containment Leak-Test Program," dated September, 1995, as modified by the following exceptions." These exceptions stated in ITS 5.5.14.a are modifications to the testing Frequencies required by 10 CFR 50, Appendix J."

Response
2/4/2010 6:45 AM Date/Time Closure Statement Response KPS agrees that no exceptions were added to the ITS and that the ISTS Statement exceptions were not included. However, ISTS specifically allows exceptions to 10 CFR 50 Appendix J to be specified in the ISTS Program, which is in the Technical Specifications. Thus, a statement that nothing in the Technical Specifications shall be construed to modify the testing Frequencies required by 10 CFR 50, Appendix J is incorrect. The ISTS allows exceptions to be made. If in the future an exception is requested by KPS, this statement could imply that it cannot be allowed. Furthermore, the statement itself is not necessary, even if there are no exceptions. The Program clearly states the requirements, and states that it is required by 10 CFR 50.54(o) and 10 CFR 50, Appendix J, Option B, as modified by approved exemptions. Thus, the CTS already states it must comply with 10 CFR 50 Appendix J (as modified by approved exemptions). Thus a statement that this cannot be modified by another Specification is unnecessary. It appears that it may be here to ensure the Frequency exceptions of SR 3.0.2 (i.e., the 25% extension allowance) are not applied.
However, SR 3.0.2 is not applicable to the Administrative Controls Chapter (or any other chapter other than Chapter 3.0) unless a specific allowance is provided (i.e., SR 3.0.2 is applicable), similar to that provided in ITS 5.5.11, Diesel Fuel Oil testing Program.

Response
2/8/2010 3:25 PM Date/Time Closure Statement Response This response supersedes the previous KPS response.
Statement KPS agrees that no exceptions were added to the ITS and that the ISTS exceptions were not included. However, the point is that the ISTS specifically allows exceptions to 10 CFR 50 Appendix J to be specified in the ISTS Program, which is in the Technical Specifications. Thus, a statement that nothing in the Technical Specifications shall be construed to modify the testing Frequencies required by 10 CFR 50, Appendix J is incorrect. The first sentence of ISTS 5.5.16.a (ITS 5.5.14.a) states "A program shall establish the leakage rate testing of the containment as required by 10 CFR 50.54(o) and 10 CFR 50, Appendix J, Option B, as modified by approved exemptions." (Italics added for emphasis) Thus, the ISTS clearly allows exceptions to be made, and a further statement saying that nothing in the Technical Specifications can be construed to modify 10 CFR 50 Appendix J is incorrect. However, KPS does note that the referenced Justification for Deviation discusses the second part of the ITS 5.5.14.a paragraph and the deleted exceptions to RG 1.163. Therefore, KPS will clarify JFD 23 to discuss the first part f the statement, as described above. Furthermore, it is believed that the deleted ISTS 5.5.16.f requirement was included in the ISTS to ensure the Frequency exceptions of SR 3.0.2 (i.e., the 25% extension allowance) are not applied. However, SR 3.0.2 is not applicable to the Administrative Controls Chapter (or any other chapter other than Chapter 3.0) unless a specific allowance is provided (i.e., SR 3.0.2 is applicable), similar to that provided in ITS 5.5.11, Diesel Fuel Oil Testing Program. In addition, the ISTS clearly states that "This program shall be in accordance with the guidelines contained in Regulatory Guide 1.163," and RG 1.163 includes the appropriate Surveillance test Frequencies and how they can be adjusted.

Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 46 of 169 DISCUSSION OF CHANGES CTS 6.0, ADMINISTRATIVE CONTROLS changes the CTS by moving the requirements for the Radiological Environmental Monitoring Program to the Offsite Dose Calculation Manual (ODCM).
The purpose of CTS 6.16.b.2 is to provide representative measurements of radioactivity in the highest potential exposure pathways, and verification of the accuracy of the effluent monitoring program and modeling of environmental exposure pathways. The removal of the requirements for this program from the Technical Specifications is acceptable because this type of information is not 5.6.1 necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. ITS 5.6.2 still requires an annual report of the results of the "Radiological Environmental Monitoring Program." Also, this change is acceptable because these requirements will be adequately controlled in the ODCM. Changes to the ODCM are controlled by the ODCM change control process in ITS 5.5.1, which ensures changes are properly evaluated.
This change is designated as a less restrictive removal of requirement change because the requirements for a program are being removed from the Technical Specifications.
LA05 (Type 4 - Removal of LCO, SR, or other TS Requirements to the TRM, USAR, ODCM, NFQAPD, CLRT Program, IST Program, ISI Program, or Setpoint Control Program) CTS Definition 1.0.o.3 contains the definition for the Process Control Program (PCP). CTS 6.16.a.1 requires written procedures for the PCP.
CTS 6.17 describes the control for changes to the PCP. The ITS does not include these requirements. This changes the CTS by moving the requirements of the PCP to the USAR.
The removal of these requirements from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The PCP implements the requirements of 10 CFR 20, 10 CFR 61, and 10 CFR 71. Compliance with these regulations is required by Kewaunee Power Station (KPS) Operating Licenses, and procedures are the method to ensure compliance with the program. Regulations provide an adequate level of control for the affected requirements and inclusion of this requirement in the Technical Specification is not necessary. Also, this change is acceptable because these details will be adequately controlled in the USAR. Any changes to the USAR are made under 10 CFR 50.59 or 10 CFR 50.71(e), which ensures changes are properly evaluated. This change is designated as a less restrictive removal of requirements because details for meeting Technical Specification and regulatory requirements are being removed from the Technical Specifications.
LA06 (Type 4 - Removal of LCO, SR, or other TS Requirement to the TRM, USAR, ODCM, NFQAPD, CLRT Program, IST Program, ISI Program, or Setpoint Control Program) CTS 6.19 requires reporting major modifications to the liquid, gaseous, and solid radwaste treatment system to the Commission as part of the Radioactive Effluent Release Report and explains what needs to be included in the report and the approval process. The ITS does not contain this requirement.
This changes the CTS by moving the requirement for reporting major modifications to the liquid, gaseous, and solid radwaste treatment system to the Offsite Dose Calculation Manual (ODCM).

Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 52 of 169 Kewaunee Diesel Fuel Oil Testing Program.
Improved Standard Technical Specification (ISTS) Section 5.5.13c requires the total particulate concentration of the emergency diesel generator fuel oil to be tested every 31 days. The current test frequency at KPS is 92 days. The licensee has proposed a deviation to ISTS to maintain the test frequency at 92 days based on:
- 1. Minimizing the number of times the outdoor fuel oil storage tanks (FOSTS) are opened, minimizes the potential for introduction of foreign materials into the tanks.
- 2. Past history indicates that 92 day test frequency was adequate for maintaining particulate content within TS limits.
Majority of the nuclear plants have a TS requirement to test fuel oil at 31 day interval.
- 1) Has KPS evaluated industry operating experience (OE) to substantiate that there is a higher incidence of introduction of foreign materials into the storage tanks at the plants with 31 day frequency?
- 2) Has KPS investigated OE methods used to exclude introduction of foreign materials into the FOSTS?
- 3) Provide details on fuel oil vendor(s) and refinery used for the last 10 years to obtain fuel oil.
- 4) Provide details on the specification, testing and quality assurance requirements imposed on the fuel oil vendor.
- 5) Provide details on measures taken to assure that future fuel oil purchases will maintain the pedigree of fuel oil received on site.
- 6) ASTM D-975 "Standard Specification for Diesel Fuel Oils" has been revised to permit up to 5% bio-diesel to be included in commercial diesel fuel without notification to the end-user. Bio-diesel is hydrophilic (attracts water) and oxidizes rapidly in storage to form corrosive acids and insoluble polymers that can adversely affect components in the EDG system and cause rapid fuel oil filter plugging. Provide details on evaluations performed to consider impact of inadvertent introduction of bio-diesel in fuel oil for 92 days.
- 7) Provide details on the material, age and the last inspection performed on the storage tank liner.

3/12/2010 10:25 AM Date/Time Closure Statement
Response
Statement KPS is adopting the requirement in ISTS 5.5.13.c to determine the total particulate concentration of the diesel fuel oil is within the limit. The ISTS Frequency for this test is every 31 days. However, this requirement is currently being performed at KPS every 92 days. KPS evaluated the maintenance history and has determined that the current licensing basis Frequency of 92 days is sufficient to ensure the total particulates stays within the new 10 mg/l limit. Therefore, KPS has submitted a 92 day Frequency in ITS 5.5.11.c, in lieu of the ISTS Frequency of 31 days.
It is the KPS position that this proposed ITS Frequency is acceptable for ensuring the total particulates remains within the 10 mg/limit. The NRC reviewer requested further information concerning the fuel oil at KPS. The following are the NRC questions and the KPS responses to the questions:
- 1. Has KPS evaluated industry operating experience (OE) to substantiate that there is a higher incidence of introduction of foreign materials into the storage tanks at the plants with 31 day frequency?
KPS response: There was no OE on the INPO web site that documents foreign material introduction into the fuel oil storage tanks from sampling. However, in KPS's situation, there is neither a sample valve nor a low point drain on the fuel oil storage tanks, which are located underground. Chemistry must remove the 4 inch flange on the top of each tank and lower the sampling equipment down into the associated tank for sampling. The connection for each tank is outside of the plant buildings (i.e., the tanks are not inside any plant building) in a gravel area with the turbine building exhaust directed to the sample area.
While KPS has not had a situation where foreign material was introduced into the tanks, there have been some near-misses. The carbon steel pipe is approximately 6 feet to the top of the tanks and is beginning to show signs of corrosion in the portion of the pipe that does not see fuel oil. Any increase in the sampling frequency will increase the possibility of introducing foreign material.
- 2. Has KPS investigated OE methods used to exclude introduction of foreign materials into the FOSTS?

Kewaunee ITS Conversion Database Page 2 of 3 Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 54 of 169 KPS response: See response to question number 1 above.
- 3. Provide details on fuel oil vendor(s) and refinery used for the last 10 years to obtain fuel oil.
KPS response: For the last 10 years, KPS has used two vendors. The current vendor is being used only because the first vendor went out of business. Both the current vendor and the previous vendor provide KPS fuel oil from the British Petroleum (BP) refinery in Whiting, Indiana.
The fuel oil is piped from the refinery to Milwaukee, Wisconsin, where it is trucked to the KPS site.
- 4. Provide details on the specification, testing and quality assurance requirements imposed on the fuel oil vendor.
KPS response: The purchase order for Amoco Premium fuel oil includes the requirement that the fuel oil must meet the requirements of ASTM D975-06 and that the vendor must provide laboratory results of the fuel oil from the tank that is used to supply KPS. Each fuel oil delivery is sampled and sent to an approved qualified laboratory for confirmation analysis. Over the last 30 years there have been no parameters found out of specification from the applicable revision of ASTM D975.
- 5. Provide details on measures taken to assure that future fuel oil purchases will maintain the pedigree of fuel oil received on site.
KPS response: The purchase specification for diesel fuel oil is a QA document and requires a Procurement Technical Evaluation performed to any changes. This document includes the references (ASTM, Calculations, basis). The changes to this document would require a full QA evaluation for revision. Furthermore, the ITS Bases for SR 3.8.3.3 provides the various required ASTM Standards to which the fuel oil is to be tested. Changes to the ITS Bases are controlled by the Bases Control Program in ITS Chapter 5. Furthermore, ITS 5.5.11 requires the diesel fuel oil program to include sampling, testing requirements, and acceptance criteria, all in accordance with applicable ASTM standards.
Thus, fuel oil purchases would have to continue to meet the ITS 5.5.11 program requirements.
- 6. ASTM-975 Standard Specification for Diesel Fuel Oils has been revised to permit up to 5% bio-diesel to be included in commercial diesel fuel without notification to the end-user. Bio-diesel is hydrophilic (attracts water) and oxidizes rapidly in storage to form corrosive acids and insoluble polymers that can adversely affect components in the EDG system and cause rapid fuel oil filter plugging. Provide details on evaluations performed to consider impact of inadvertent introduction of bio-diesel in fuel oil for 92 days.
KPS response: This concern over Bio-diesel was communicated to KPS Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 54 of 169 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2551 06/07/2010
Kewaunee ITS Conversion Database Page 3 of 3 Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 55 of 169 in the form of an Information Notice and the response to this IN was documented in the KPS corrective action program. The KPS fuel oil purchase order specifically states that Bio-diesel will not be allowed.
KPS is purchasing laboratory equipment to analyze for Bio-diesel and the contract laboratory also analyzes for Bio-diesel as part of each shipment. All results indicate less than detectable Bio-diesel.
- 7. Provide details on the material, age and the last inspection performed on the storage tank liner.
KPS response: The two fuel oil storage tanks are made of carbon steel and are original equipment (i.e., circa 1971). The last inspection of the two fuel oil storage tanks was completed in 2001. The results of the inspection only found some indications from initial installation and no other concerns.

Response
Statement Kewaunee Power Station (KPS) recently had an informal phone conversation with the NRC reviewer discussing his comment provided in VGC-008 and the subsequent KPS response. During the conversation, many issues were discussed concerning the sampling of diesel fuel oil at KPS. The following is a list, provided by the NRC, of the various issues discussed, including the NRC's understanding of what transpired during the phone call. For each of the listed issues, KPS is providing a confirmation or follow-up response to the issue.
- 1. Sampling method, I believe the licensee said according to ASTM D4057, "Standard Practice for Manual Sampling of Petroleum and Petroleum Products."
KPS Response: Both SP-10-225, the relevant KPS-specific surveillance procedure, and CY-AA-AUX-310, the relevant Dominion fleet procedure include reference to ASTM D4057. A comparison of SP-10-225 with ASTM D4057 indicates that this sampling methodology is in accordance with ASTM D4057.
- 2. "All- level" sample method is used every 92 days.
KPS Response: KPS surveillance procedure SP-10-225 specifies a quarterly sampling frequency for each Diesel Fuel Oil Storage Tank.
The Dominion fleet procedure CY-AA-AUX-310 specifies a 92 day sampling frequency and in accordance with the KPS surveillance procedure (i.e., SP-10-225). The "All-level" sample method is used for the fuel oil storage tanks.
- 3. By procedure, delivery tank is steam cleaned prior to filling by supplier.
KPS Response: By purchase order, the following quality assurance requirement is invoked: "Prior to filling, transporters and hoses are to be steam cleaned and dried. Vendor shall provide documented evidence of cleaning prior to or with shipment. All hoses to be used for off load shall be capped to prevent road contaminates from entering during transit."

Kewaunee ITS Conversion Database Page 2 of 3 Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 57 of 169
- 4. A certificate is provided by the fuel oil supplier indicating conformance with purchase order.
KPS Response: The purchase order requires that the fuel oil shall be supplied in accordance with the requirements, analysis, and limits specified in Dominion fleet procedure CY-AA-AUX-310. Per the purchase order requirement, the supplier provides a laboratory analysis report for the last shipment received at the local fuel oil facility at or before the shipment to Kewaunee, and documented evidence of steam cleaning and drying of transporter compartments prior to, or with, shipment of fuel.
- 5. Fuel oil sample from delivery truck taken by onsite Chemistry personnel prior to filling the fuel oil storage tank.
KPS Response: KPS surveillance procedure SP-10-225 requires a fuel oil sample to be taken from the transporter, and the Immediate Fuel Oil Acceptance Criteria confirmed acceptable prior to transferring (i.e.,
offloading) fuel oil into a fuel oil storage tank.
- 6. Fuel sample from every new delivery is sent to a recognized lab for analyses and response is required within 20 days.
KPS Response: KPS surveillance procedure SP-10-225 requires fuel oil samples to be sent to the offsite vendor laboratory for analysis within 5 days of obtaining the samples. The procedure states that analytical results should be received from the offsite vendor within 14 days of the vendors receipt of the sample. Kewaunees review and evaluation of sample analytical results are required to be completed within 30 days of sampling new diesel fuel receipt.
- 7. The fuel sample from the fuel oil storage tank is taken using a tygon tube and no canisters, bacon bombs, glass containers, etc., are introduced into the tank.
KPS Response: The fuel oil sample from each fuel oil storage tank is taken using tygon tubing and a peristaltic pump. No sample canisters, sample thieves, bacon bombs, glass containers, etc., are introduced into the tank during the acquisition of these samples.
- 8. Day tank oil is sampled every 30 days.
KPS Response: The current KPS Preventive Maintenance Procedure PMP-10-02 includes the DG A/B Day Tanks fuel oil sampling, and is scheduled on a monthly basis. This is consistent with the proposed ITS SR 3.8.1.5; a new surveillance procedure is in development for this purpose.
- 9. Tanks are directly buried carbon steel. Check on corrosion protection Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 57 of 169 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2881 06/07/2010
Kewaunee ITS Conversion Database Page 3 of 3 Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 58 of 169 (cathodic protection, coating, etc.).
KPS Response: The fuel oil storage tanks are buried, coal tar mastic coated carbon steel tanks. Additional corrosion protection is provided by a cathodic protection system.
- 10. The 'sump' part of the tank is not known, i.e. if the tank is built on a slant, the water and debris will settle at one end, which may be the suction end for the transfer pumps. Need to identify the height elevation of the suction line in relation to the elevation of the bottom of the tank to provide assurance that water and sediment will not be introduced into the EDG. 10 year cleaning did not show any concerns.
KPS Response: The fuel oil storage tanks are horizontal right circular cylinders, with no sump. Calculation C10033, Rev. 2, Safeguards Diesel Fuel Oil Storage Volume Calculation, indicates that the installed fuel oil transfer pump suction is 4 3/8 inches above the bottom of the tank, providing reasonable assurance that water and other sediment will not be introduced into the suction of the fuel oil transfer pumps.
Additionally, the quarterly fuel oil sampling (i.e., KPS surveillance procedure SP-10-225) includes a bottom sample which serves to remove settled contaminants and water. Further, the most recent cleaning and visual inspection of the underground fuel oil storage tanks indicated no unacceptable degradation.

RE: ME 2139 - Kewaunee TS 5.5 Diesel Fuel Oil Testing Program RAI Close-out Date: Thursday, May 06, 2010 9:58:54 AM Vic, This e-mail confirms my concurrence to the responses provided by Kewaunee for LAR converting Current Technical Specification (CTS) requirements to Standard Technical Specification (STS) format related to Emergency Diesel Generator (EDG)
Fuel Oil Storage Tank (FOST) sampling.
Specifically, Kewaunee CTS does not require sampling of EDG fuel oil in the FOSTs. The licensee currently has plant procedures (non-TS) that call out testing the particulate concentration of the fuel every 92 days, and they would like to maintain that frequency rather than adopting the 31 days in the STS.
The licensee has provided details on current procedures that ensure that new particulate or bio-diesel products are not introduced into the FOSTs. The licensee has not noticed significant moisture or particulate accumulation in the FOSTs during the clean up required every 10 years. The licensee will sample the day tanks every month (per STS requirement) providing assurance that any excessive moisture and sediment build up in the FOSTs that gets carried into the day tanks will be detected during the monthly surveillance. Based on the licensee's responses to staff 's request for additional information and subsequent supplemental questions related to fuel oil sampling methods, the staff finds the proposed sampling of fuel oil in the FOSTs, every 92 days instead of 31 days, as acceptable.
Please retain all the responses provided by the licensee, related to this Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 59 of 169 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2891 06/07/2010

Response
4/22/2010 2:10 PM Date/Time Closure Statement Response The current Kewaunee Power Station (KPS) commitment is to Regulatory Statement Guide (RG) 1.52, Rev 1, with respect to replacement HEPA filters and charcoal adsorbers. Therefore, this is the current version of the RG KPS uses as guidance to perform the inplace HEPA filters and charcoal adsorbers. However, KPS has reviewed Revision 2 of the RG and will adopt the Revision 2 testing methods for these two tests. A draft markup regarding this change is attached. Note that this attached change includes changes due not only to this response, but also includes changes identified in the KPS responses to VGC-010 and VGC-011. This change will be reflected in the supplement to this section of the ITS conversion amendment. In addition, a clean draft markup of ITS 5.5.9, which shows how the ISTS Markup will look when the revision to the ITS submittal is made (i.e., the Rev. 1 version of the ISTS Markup), is also included to assist in understanding the changes.

In WPS letter of August 25, 1976 to Mr. Al Schwencer (NRC) from Mr. E. W. James, we relayed test results for flow distribution for tests performed in accordance with ANSI N510-1975. This standard refers to flow distribution tests performed upstream of filter assemblies.
Since the test results upstream of filters were inconclusive due to high degree of turbulence, A07 tests for flow distribution were performed downstream of filter assemblies with acceptable results (within 20%). The safety evaluation attached to Amendment 12 references our letter of August 25, 1976 and acknowledges acceptance of the test results.

Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 68 of 169 DISCUSSION OF CHANGES ITS 5.5, PROGRAMS AND MANUALS found in ITS 5.5.13. This change is designated as more restrictive because it imposes additional programmatic requirements in the Technical Specifications.
M10 The CTS does not include a requirement for Battery Monitoring and Maintenance Program. The ITS includes a requirement for this program. This changes the CTS by adding the ITS 5.5.15, "Battery Monitoring and Maintenance Program."
The Battery Monitoring and Maintenance Program is included to provide for battery restoration and maintenance. The specific wording associated with this program may be found in ITS 5.5.15. This change is acceptable because it supports implementation of the requirements of the ITS. This change is designated as more restrictive because it imposes additional programmatic requirements in the Technical Specifications.
M11 The CTS does not have a program for Setpoint Control. ISTS 5.5.18 (ITS 5.5.16) requires a program to satisfy the regulatory requirement of 10 CFR 50.36(c)(1)(ii)(A) that Technical Specifications will include items in the category of limiting safety system settings (LSSS), which are settings for automatic protective devices related to those variables having significant safety functions. This changes the CTS by incorporating the requirements of ISTS 5.5.18 (ITS 5.5.16).
The purpose of the program is to establish, implement, and maintain instrument setpoint controls for automatic protective devices related to those variables having significant safety functions. This change is designated as more restrictive because it imposes new programmatic requirements in the Technical Specifications.
NSERT DOC M13 RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES LA01 (Type 3 - Removing Procedural Details for Meeting TS Requirements or Reporting Requirements) CTS 6.18.b.1 requires changes to the ODCM to be documented and records of reviews performed to be retained as required by the quality assurance program. CTS 6.18.b.2 requires changes to the ODCM to be effective after review and acceptance by the PORC. ITS 5.5.1.c.1 requires changes to the ODCM to be documented and records of reviews performed to be retained. ITS 5.5.1.c.2 requires changes to the ODCM to become effective after the approval of the plant manager. This changes the CTS by moving the record retention requirements reference and the PORC review and approval requirements to the Nuclear Facility Quality Assurance Program Description (NFQAPD). DOC M01 describes the addition of the plant manager approval.
The removal of these details, which are related to meeting Technical Specification requirements, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Kewaunee Power Station Page 7 of 8 Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 68 of 169
Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 69 of 169 INSERT M13 CTS 3.6.c.3.A, 3.6.c.3.C, 3.8.a.9.b.1, 3.8.a.9.b.3, 3.12.c.1, 3.12.c.3, 4.4.c.1.a, 4.4.c.3, 4.4.d.1, 4.12.a.1, and 4.17.a.1 require certain Ventilation System filter tests to be performed at the system design flow rate. However, no specific value of the various Ventilation System design flow rates is provided. ITS 5.5.9.a, b, d, and e require performance of similar Ventilation System filter tests, and include the specific value of the design flow rate for each required Ventilation System. This changes the CTS by adding the specific design flow rate values into the filter test requirements of the ITS.
The various Ventilation System filter tests are performed at the system design flow rate.
However, the specific values are currently controlled in plant procedures and the USAR. This change will add the values into the Technical Specifications, and thus any change will require NRC approval in lieu of changing it by the 10 CFR 50.59 process. Therefore, this change is considered acceptable. This change is designated as more restrictive because new Ventilation System design flow rate values are being included in the ITS that are not required in the CTS.
Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 69 of 169
Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 70 of 169 DISCUSSION OF CHANGES ITS 5.5, PROGRAMS AND MANUALS Specifications to provide adequate protection of public health and safety.
ITS 5.5.1 still retains the requirement for changes to the ODCM to be documented and retained. Also, this change is acceptable because these types of procedural details will be adequately controlled in the NFQAPD. Any changes to the NFQAPD are made under 10 CFR 50.54(a), which ensure changes are properly evaluated. This change is designated as a less restrictive removal of detail change because procedural details for meeting Technical Specifications requirements are being removed from the Technical Specifications.
LA02 (Type 4 - Removal of LCO, SR, or other TS requirement to the TRM, USAR, ODCM, NFQAPD, CLRT Program, IST Program, ISI Program, or Setpoint Control Program) CTS 4.2.a and 4.2.a.1 provide requirements for the In-Service Inspection Program. The ITS does not include In-Service Inspection Program requirements. This changes the CTS by moving these requirements from the Technical Specifications to the In-Service Inspection (ISI) Program.
The removal of these requirements is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The Technical Specifications still retain requirements for the affected components to be OPERABLE. Also, this change is acceptable because these requirements will be adequately controlled by the ISI Program, which is required by 10 CFR 50.55a.
Compliance with 10 CFR 50.55a is required by the Kewaunee Operating License. This change is designated as a less restrictive removal of requirement change because requirements are being removed from the Technical Specifications.
LESS RESTRICTIVE CHANGES L01 (Category 1 - Relaxation of LCO Requirements) CTS 6.20.b states, in part, that the leakage rate acceptance criteria prior to unit startup for the Type A test is
< 0.75 La. ITS 5.5.14.d.1 states, in part, that the leakage rate acceptance criteria prior to unit startup for the Type A test is 0.75 La. This changes the CTS by allowing the leakage rate to be exactly equal to 0.75 La in lieu of being < 0.75 La.
The purpose of ITS 5.5.14.d.1 is to ensure that prior to a unit startup the overall containment leakage rate with a certain amount of margin, does not exceed the value assumed in the accident analysis. This change is acceptable because the acceptance criteria limit in ITS 5.5.14.d.1 (the 1.0 La limit) continues to ensure the containment leakage is within the value assumed in the accident analysis. The 10CFR50 Appendix J Option B states that for Type A tests the leakage rate must not exceed the allowable leakage rate (La) with margin, as specified in the Technical Specifications. The ITS now provides a margin that includes allowing the limit to be exactly 0.75 La. This change is designated as less restrictive because the acceptance criteria applicable prior to a unit startup for the Type A leakage tests is now allowed to be exactly equal to 0.75 La in lieu of being
< 0.75 La.

Enclosure, Q&A to Attachment 1, Volume 16 (Chapter 5.0) 71 of 169 L02 (Category 1 - Relaxation of LCO Requirements) CTS 4.4.c.1.a provides the pressure drop test acceptance criteria for the Shield Building Ventilation System (SBVS) and the Auxiliary Building Special Ventilation (ASV) System. The acceptance criteria are a pressure drop across the combined HEPA filters and charcoal adsorber banks < 10 inches of water and a pressure drop across any HEPA filter bank < 4 inches of water. CTS 4.17.a.1 provides the pressure drop test acceptance criteria for the Control Room Post Accident Recirculation (CRPAR) System. The acceptance criteria are a pressure drop across the combined HEPA filters and charcoal adsorber banks < 6 inches of water and a pressure drop across any HEPA filter bank < 4 inches of water. ITS 5.5.9.d provides the pressure drop test acceptance criteria for all three systems, and requires the pressure drop across the combined prefilters, HEPA filters, and charcoal adsorber banks to be < 6.3 inches of water for the SBVS and the ASV System, and < 2.4 inches of water for the CRPAR System. This changes the CTS by reducing the acceptance criteria for the combined dP, including the prefilters as part of the combined dp test, and deleting the HEPA filter only dP criteria.
Performance testing demonstrating that dP is within prescribed limits assures that fans operate within +/- 10% of design flow, and thus ensures that filters perform adequately to satisfy the accident analyses. That is, if the performances are as specified, the calculated doses would be less than the guidelines stated in 10CFR Part 100 for the accidents analyzed.
During the development of Design Basis Documents for these ventilation systems it was identified that the analytical basis for the CTS dP acceptance criteria could not be verified. KPS has recently performed calculations, based on a newly developed analytical basis. These calculations have determined that the current dP acceptance criteria are non-conservative. KPS has implemented, in procedures, these more restrictive acceptance criteria. This change to the CTS replace the non-conservative dp acceptance criteria with the current acceptance criteria from the recent calculation. This change is acceptable because it will incorporate newly calculated, and more conservative, dP acceptance criteria.
Combined dP testing across the prefilter, HEPA filter and charcoal adsorber banks, per the ISTS format, in lieu of CTS combined HEPA filter and charcoal adsorber bank and HEPA-only dP testing, will still adequately demonstrate that the filters are not clogged and capable of performing their design function.
The change related to the reduction of the combined dP limit is more restrictive, since it is reducing the limit and adding another component (prefilter) to the testing. However, the change related to removing the HEPA filter only dP limit is less restrictive. Therefore, this change is designated as less restrictive because the acceptance criteria applicable to the HEPA filter only dP test is being deleted.

ASTM D 3803-1989 is a more stringent testing standard because it does not differentiate between used and new charcoal, it has a longer equilibration period performed at a temperature of 30°C (86°F) and a relative humidity (RH) of 95%
(or 70% RH with humidity control), and it has more stringent tolerances that improve repeatability of the test.

Safety factor 2 for systems with or without humidity control. 15 Humidity control can be provided by heaters or an NRC-approved analysis that demonstrates that the air entering the charcoal will be maintained less than or equal to 70 percent RH under worst-case design-basis conditions.
If the system has a face velocity greater than 110 percent of 0.203 m/s (40 ft/min), the face velocity should be specified.

- 9. The Inservice Testing Program (ISTS 5.5.8) has been modified to state that the IST Program provides control for ASME Code Class 1, 2, and 3 "pumps and valves" in place of the current "components." 10 CFR 50.55a(f) provides the regulatory requirements for the IST Program. It specifies that ASME Code Class 1, 2, and 3 pumps and valves are the only components covered by an IST Program. 10 CFR 50.55a(g) provides regulatory requirements for an Inservice Inspection (ISI) Program. It specifies that ASME Code Class 1, 2, and 3 components are covered by the ISI Program, and that pumps and valves are covered by the IST Program in 10 CFR 50.55a(f). The ISTS does not include ISI Program requirements as these requirements have been relocated to a plant specific document. Therefore, the components to which the IST Program applies (i.e., pumps and valves) have been added for clarity. In addition, the statement "The program shall include the following:" has been deleted because not all of the statements that follow are really part of the program requirements.
Furthermore, the terms weekly, semiannually, and every 9 months have been deleted since these terms are not used in the ASME OM Code.
- 10. ITS 5.5.9.a, b, and d include a requirement for the system nominal flowrate value to be specified. ITS 5.5.9.a, b, and d do not include the specific nominal flowrate.
ITS 5.5.9.a, b, and d specify that the flowrate is the "system design flowrate."
Not used. This is consistent with the CTS, since the CTS does not include specific values for each of the safety related ventilation systems. The CTS (CTS 3.6.c.3.C, 3.12.c.3, 4.4.c.1.a, 4.4.c.3, and 4.17.a.1) only includes the requirement that the tests be conducted at the system design flowrate (+10%).
- 11. ISTS 5.5.11 uses the term "Engineered Safety Feature (ESF)" to describe the ventilation systems tested as part of this Specification. The three ventilation systems covered in ITS 5.5.9 are the Shield Building Ventilation System (SBVS),
Auxiliary Building Special Ventilation (ASV) System, and Control Room Post Accident Recirculation (CRPAR) System. The KPS CRPAR System is not an ESF. Therefore, the term has been changed to "safety related," since all three of the ventilations systems are safety related.
- 12. The Reviewer's Note to ISTS 5.5.9.c and the subsequent wording states alternate tube repair criteria that are currently permitted by the plant technical specifications should be provided in the ITS. ISTS 5.5.9.f (ITS 5.5.7.f), including the Reviewer's Note, states, in part, the tube repair methods currently permitted by plant technical specifications should be provided in the ITS. The bracketed allowance to provide steam generator tube repair criteria and methods are not included since the current KPS Steam Generator Program does not allow repair; only plugging is allowed.
- 13. Kewaunee Power Station has steam generators with Alloy 690 thermally treated tubing. Therefore the third option is maintained, consistent with the current Technical Specifications.

A draft markup regarding this change is attached to the KPS response to VGC-009. Note that the attached change includes changes due not only to this response, but also includes changes identified in the KPS responses to VGC-009 and VGC-011. This change will be reflected in the supplement to this section of the ITS conversion amendment. In addition, a clean draft markup of ITS 5.5.9, which shows how the ISTS Markup will look when the revision to the ITS submittal is made (i.e., the Rev. 1 version of the ISTS Markup), is also included and attached to the KPS response to VGC-009 to assist in understanding the changes.

Response
4/22/2010 2:15 PM Date/Time Closure Statement Response The current Kewaunee Power Station (KPS) licensing basis is as the Statement proposed ISTS markup shows. That is, the specific flow rates are not identified in the CTS; only a statement that the flow rates are the design flows. However, KPS has re-reviewed the issue and will include the current design flows in the ITS. Furthermore, due to a recent calculation that recalculated the design flows, the dp acceptance criteria for ITS 5.5.9.d has also been affected. Therefore, the dp acceptance criteria has also been changed and is included as part of this change. A draft markup regarding this change is attached to the KPS Response to VGC-009. Note that the attached change includes changes due not only to this response, but also includes changes identified in the KPS responses to VGC-009 and VGC-010. This change will be reflected in the supplement to this section of the ITS conversion amendment. In addition, a clean draft markup of ITS 5.5.9, which shows how the ISTS Markup will look when the revision to the ITS submittal is made (i.e., the Rev. 1 version of the ISTS Markup), is also included and attached to the KPS response to VGC-009 to assist in understanding the changes. Furthermore, the calculations that support the design flows and the dp acceptance criteria for the three affected systems (Shield Building Ventilation System, Auxiliary Building Special Ventilation System, and Control Room Post Accident Recirculation System) are attached to this response.

2.0 BACKGROUND
Currently there is conflicting infonnation regarding the proper design flow rate of the SBV system. Reference 5.1 states that the SBV System Design Flow rate is 5,000 SCFM. Reference 5.2 states that the SBV System flow rate is 6,000 CFM +/-10%. The Reference 5.33 and 5.34 SBV filter test procedures state that the SBV fan flow during SBV filter testing should be between 4,500 and 6,600 CFM. The technical specifications (tech spec) state that the allowable SBV system flow rate is the system design flow rate +/-10%. The maximum permissible value of 6,600 CFM given in the test procedures is higher than the Reference 5.1 design flow rate of5,000 CFM
+10% (5,500 CFM). Further, the Reference 5.24 through 5.27 test data show that the actual SBV flow rates are around 5,700 SCFM, which is also above 5,500 CFM. From this conflicting information, the recommended system design flow rate needs to be determined. A PROTO-HVAC model of the SBV system will be constructed and used to determine the required system design flow rate. After the correct SBV design flow rate is determined, the pressure drops across the filter and certain filter components at the design flow rate and the design flow rate -10% (tech spec minimum permissible value) will be compared to the current tech spec pressure drops.
3.0 INPUTS AND ASSUMPTIONS 3.. 1 DESIGN INPUTS 3.1.1 Duct physical infonnation, such as lengths, number and type of fittings, and damper information, was taken from References 5.1 through 5.8 and Reference 5.21.
3.1.2 Fan curve data was provided by Reference 5.9.
3.1.3 Test data filter pressure drop and flow information for all filter components was provided by References 5.24 through 5.27. An uncertainty analysis was not perfonned for this calculation because test data uncertainty infonnation was not available.
3.1.4 Vendor supplied pressure drop values for clean filter conditions for the electric heating coil, prefilter, and charcoal filter were provided by Reference 5.19. Reference 5.19 includes components purchased for the filter assemblies in this calculation. Reference 5.20 confinns that the data pages in Attachment H are from Reference 5.19..

3.1.6 Where duct sections contained more than 2 different angled bends, subsequent bends were input as Misc. K fixed resistances, as calculated per Reference 5.28.
3.2 ASSUMPTIONS 3.2.1 For all analyses in this calculation, it is assumed that the SBV system is operating with the modulating dampers positioned to maintain an annulus pressure of -0.6" WC based on Reference 5.10, section 1.4.
3.2.2 It is assumed that dampers CD34124 and CD34127 in the recirculation lines are positioned at 5/8 open (33.75° from centerline in PROTO-HVAC model) and dampers CD34125 and CD34128 in the exhaust lines are positioned at 3/8 open (56.25° from centerline in PROTO-HVAC model) when these dampers are in service. The SBV Monthly test data in References 5.11 through 5.17 all list the dampers positioned thusly. All other dampers are either fully opened or fully closed based on the train being run.
3.2.3 It is assumed that atmospheric pressure at Kewaunee Power Station is 14.375 psia based on the analysis in Reference 5.18.
3.2.4 The clean pressure drop across the moisture separator is assumed to be 0.09" WG at 5,776 SCFM
(.067" WG at 5,000 SCFM) because this is the lowest value for this component from the Reference 5.24 through 5.27 test data. This is a reasonable clean DP because it is considerably less than the value of 0.5" WG given in Reference 5.32 for when the moisture separator should be changed due to a dirty filter.
3.2.5 For all analyses, air conditions of 70°F and 50% relative humidity were assumed, which are typical conditions for HVAC applications.
3.2.6 Reference 5.1 shows four backdraft dampers downstream of fans 1A and 1B without tags. For the PROTO-HVAC model, these dampers were labeled as "BD" followed by the number of the duct in which they are located. The backdraft damper in duct 17.1 is given the number 171 to avoid complications in using a decimal point in the label.
3.2.7 Reference 5.8 shows dampers without tags just upstream of the duct outlets. For the PROTO-HVAC model, these dampers were labeled as "Damper" followed by the number of the duct in which they are located.
3.2.8 It is assumed that all filter components, with the exception of the heater and charcoal filter, become clogged at the same rate. This is conservative because if only one filter component Form No.: P030105 sheet 1 of 1 Rev.: 0-01 Date: Ref.: P 3-1

3.2.9 The maximum combined filter pressure drop permissible across the charcoal and REPA filter banks is assumed to be lOin WG and the maximum pennissible pressure drop across a REPA filter bank is 4 in WG, per Reference 5.29.
3.2.10 The Reference 5.26 test data does not contain a DP for the moisture separator (demister), so the pressure drop for this component was assumed the same as that given in the Reference 5.24 data.
3.2.11 It is assumed that the flow resistance of the heaters will not increase above the value given in Reference 5.19. The heaters are heating coils and not filters and are thus not likely to become clogged with debris the way filters become clogged. Thus, for all analyses, the Reference 5.19 pressure drop and flow values, or the equivalent resistance at a different flow rate, were used for the heater.
3.2.12 It is assumed that the pressure drop across the charcoal filters will not increase beyond the values given in the Reference 5.24 through 5.27 test data because the charcoal filters do not filter particulate matter.
3.2.13 The pressure drop across the REPA filters for vendor specified clean conditions is assumed to be 0.789" WG since the Reference 5.19 data did not specify a pressure drop for the REPA filters.
This value was obtained as follows: The total filter pressure drop for clean conditions through the filters is 3+/-0.3in WG per Reference 5.20, which means the lowest pressure drop can be 2.7" WG.
This value will be used to detennine the HEPA pressure drop because the minimum possible DP will yield the highest flow rate, and for case run in section 6.2 where this value is used, the objective is to maximize the flow rate. The sum of the pressure drops across the filter components, excluding the REPA filters is 1.122 in WG per Reference 5.19 and Assumptions 3.2.4 and 3.2.11. The pressure drop across the REPA filters is calculated as the difference between the total pressure drop and the non-REPA pressure drop, 2.7" WG -1.122" WG =
1.578" WO. The pressure drop for each REPA filter bank is half this value, 0.789" WG.
3.2.14 The maximum SBV system flow rate is assumed to be the design flow rate +10% and the minimum is assumed to be the design flow rate -10%, per Reference 5.29.
3.2.15 All analysis was done for one train operation because filter testing is done one train at a time per References 5.33 and 5.34 and all test data is thus for one train operation. Flow rate and pressure drop values are specified on a per train basis.
3.2.16 The material for all ducts except duct #1 and 7 was assumed to be "Galvanized Sheet Duct (12 joints!! 00 ft)" from the PROTO-HVAC library. The material for duct #1 and 7 is "Spiral Form No.: P030105 sheet 1 of 1 Rev.:

It was assumed that this material applied to the entire duct section, not just the section shown on the Referenced drawing. This reference also indicates that several other duct sections are constructed of spiral galvanized duct. However, during the benchmarking process, the roughness of these ducts was changed from galvanized sheet duct to spiral galvanized duct, and this change had a negligible impact on the calculated flow rates; the flow rates were reduced very slightly.
Since the calculated flows were already below the test flows, the galvanized sheet duct was used to better match the test flow rates.
3.2.17 Flow rate values in Reference 5.19 were assumed to be in SCFM, as this is typical for fan curve flow rates.
nd 3.2.18 The location of the heaters in the filter assembly is assumed to be after the 2 bank of HEPA filters. The arrangement of the filter components in the flow path is inconsequential since the components are all in series and total pressure drop is simply the sum of component pressure drops.
4.0 METHODOLOGY This calculation has been developed using PROTO-HVAC Version 1.01. The PROTO-HVAC software was developed and validated in accordance with Zachry's Nuclear Software Quality Assurance Program (SQAP), Reference 5.22. This program meets the requirements of IOCFR50 Appendix B, 10CFR21, and ANSI NQA-l, and was developed according to the guidelines and standards contained in ANSI/IEEE Standard 730/1984 and ANSI NQA-2b-1991.
The creation of the Shield Building Ventilation System model database consisted of the following steps:
- 1. Define the system from a schematic as a network of connecting node points.
- 2. Gather detailed data including duct lengths, fitting and component infonnation for the ducting and components between each node point.
- 3. Enter this information into the appropriate field within PROTO-HVAC. Once this system data has been entered into the database, system operation can be evaluated for the desired operating conditions.
Three case files were created to complete the analyses in the calculation. File SBV-BENCHMARK.DBD was used for the analysis in section 6.1 to compare the PROTO-HVAC results to test data. After the model was benchmarked, this case was used to determine the recommended system design flow rate. File SBV-VENDCLEAN.DBD was used in section 6.2 Form No.: P030105 sheet 1 of 1 Rev.:

File SBV-MINFLOW.DBD was used in section 6.4 to determine the filter component pressure drops that would yield the minimum flow rate of the recommended design flow rate -10%.
Fan performance is modeled with the fan curve on page 135 of Attachment A. On the fan curve, several pressure data points for flow values lower than 4,500 SCFM were artificially added to the curve to create a fan curve that had a continuously decreasing discharge pressure with increasing flow. This type of fan curve is required for PROTO-HVAC to converge successfully. The actual fan curve does not have continuously decreasing discharge pressure with increasing flow for flow rates below approximately 4,500 SCFM, so below this value the curve was modified to create a constantly decreasing discharge pressure. For flow rates above 4,500 SCFM, the fan curve in the PROTO-HVAC model is accurate. Since in the model the fan is operating on its curve at a value above 4,500 SCFM, when the model converges the fan operating point will be on the accurate portion of the fan curve and model accuracy will not be affected. If the model is used in the future for flow rates less than 4,500 SCFM, the fan curve will have to be changed to obtain accurate results.
Once the model was created, it was benchmarked against the Reference 5.24 through 5.27 test data. Model Filter component DPs were set to match the filter DPs given in the test data at the flow rates given in the test data. The model was run to obtain a calculated system flow rate and a comparison was made between the calculated flow rates and the test flow rates. With the model adequately benchmarked, the calculated flows and test flows were used to determine the proper design flow rate for the system. Once the design flow rate was detennined, the component filter pressure drops that yielded the minimum pennissible system flow of the design value -10% were detennined to compare these values to the tech. spec. component filter pressure drop values.
PROTO-HVAC calculates flow in ACFM, so calculated flows were corrected to SCFM as follows:
Pf Qs =Qfx- (equation 1)
Ps Where, Qf == actual volume flow rate (ACFM)
Qs == standard volume flow rate (SCFM)
Ps == air density at standard conditions, 0.075 Ibm/ft3 (Reference 5.30)
Pf == air density at the applicable duct section (lbm/ft3)

6.0 CALCULATIONS AND RESULTS 6.1 BENCHMARK C011PARISON The Reference 5.24 through 5.27 test data was used to benchmark the PROTO-HVAC model to measured flow and pressure drop information. Benchmarking was done for each train, A and B.
Benchmarking was done by setting the filter component pressure drop and corresponding flow rate in the model to match the test data (see Table 2 and Table 4 for measured flow rates), and then running the model and comparing the calculated fan flow rate to the measured fan flow rate.
The DP and flow values for each train were averaged together, and the average values were used in the PROTO-HVAC model. A verification was done to compare the equivalent component DPs at the average flow rates to the average DP values in Table 1 and Table 2 and this showed that the error introduced in averaging these values was less than the amount of significant figures reported in the tables. For Train A, the pressure drop test data for the filter components is listed in Table 1 and the benchmarking results are in Table 2. For Train B, the pressure drop test data is listed in Table 3 and the benchmarking results are in Table 4. The model file "SBV-BENCHMARK.DBD" was used for this analysis, and pertinent output reports are included in Attachment B.

6.2 FLOW RATE WITH VENDOR-SUPPLIED COMPONENT PRESSURE DROPS Each train of the SBV system was run with the vendor component pressure drops given for clean filter conditions. The flow rate entered into the model corresponding to the pressure drop is 5,000 SCFM. Where the vendor data gave a component pressure drop at a flow rate other than 5,000 SCFM, the pressure drop was converted to a value at 5,000 SCFM using the following fonnula:
(equation 2) where:
Ql = given flow rate LlPl = pressure drop at Ql Q2 = flow rate for which pressure drop is desired LlP 2 = pressure drop at Q2 The pressure drops used for both trains are given in Table 5, below:

- 1. See Assumption 3.2.4
- 2. See Assumption 3.2.13 The model was run using the Table 5 pressure drops to determine the system flow rate under these filter conditions. The system flow rates calculated for each train, as determined using the PROTO-HVAC Fan Status Report (included in Attachment C), are given in Table 6, below. The model file "SBV-VENDCLEAN.DBD" was used for this analysis and the pertinent output reports are included in Attachment C.
Table 6 - Calculated System Flow rates for Vendor Supplied Filter DPs flow rate flow rate (ACFM) (SCFM)
TrainA 5837 5565 TrainB 5761 5523 The analysis in this section was completed to determine if the system flow rates when the filters were at clean conditions as specified in the vendor data would be substantially higher than the flow rates observed in the test data. When the component pressure drops in Table 5 are converted to the equivalent pressure drops at the test flow rates of 5,735 SCFM for Train A and 5,751 SCFM for Train B, the total filter resistance is higher than the filter resistance given in the test data, and thus the system flow rates are lower, as indicated in Table 6. If the flow rates determined here were substantially higher than the test data flow rates, the higher flow rates would be an indication of the maximum possible system flow rate. Since the calculated system flow rates obtained when using the vendor supplied clean filter DPs are less than the flow rates calculated when using the test data filter DPs in Section 6.1, this means that the current system filters are less restrictive than the filters meeting the vendor specified flow and DP values for clean filters and it is conservative to use the benchmark case as the clean filter case.
6.3 RECOMl\1ENDED SYSTEM DESIGN FLOW RATE The recommended SBV system design flow rate is 5,700 SCFM. In order for the charcoal filters to effectively remove contaminants from the air flow, the flow through the filters must be between 4,510 SCFM - 6,600 SCFM, per Reference 5.~3, and 5,700 SCFM is soundly within this range. The Reference 5.2 accident analysis uses a SBV system flow rate of 6,000 SCFM
+/-10%, which gives a range of 5,400 SCFM - 6,600 SCFM, and 5,700 SCFM is within this range also. References 5.33 and 5.34 state that the fan flow must be between 4,500 SCFM and 6,600 SCFM when the system is tested, and 5,700 SCFM is also within this range. If+/-10% is applied to 5,700 SCFM, the flow range is 5,130 SCFM - 6,270 SCFM, and this range is within the flow P030105 sheet 1 of 1 Rev.: 0-01 Date: Ref.: P 3-1 Form No.:

The PROTO-HVAC analyses and test data show that the SBV system flow is around 5,700 SCFM, and given the system resistance using vendor supplied component pressure drops for clean filters, it is unlikely that the system flow rate will be substantially above 5,700 SCFM in the current configuration. Since the model and test data show system operation of approximately 5,700 8CFM and 5,700 SCFM meets all the requirements discussed for fan flow, charcoal filter flow, and accident analysis flow, it is recommended that 5,700 SCFM be the SBV system design flow rate.
6.4 MINIMUM FLOW WITH DIRTY FILTERS The component pressure drops were increased above the test data values until the system flow was reduced to the minimum permissible value of the design flow rate -10%, which is 5,130 SCFM. The average test data pressure drops were used as the starting values rather than the vendor supplied clean pressure drops because the test data pressure drops are less restrictive than the vendor supplied clean pressure drops, as shown in Section 6.2. The test data pressure drops were converted to pressure drops at 5,130 SCFM from the average test data flow rates using equation 2 to facilitate the comparison in DP between design flow and minimum flow. The values used as the starting values for each component are given in Table 7.

The charcoal filter pressure drop was also kept at its benchmarked value because the charcoal filter does not remove particulate matter. All other filter component pressure drops were increased by the same percentage from their test data value until the system flow rate for each train reached the target of 5,130 SCFM. The pressure drops at this condition are reported in Table 8 for both trains. The model file "8BV-MINFLOW.DBD" was used for this analysis and the pertinent output reports are included in Attachment D.

6.5 MOTOR HORSEPOWER REQUIRED Reference 5.9 shows that the SBV fan blade setting is halfway between #8 and #10. Using the horsepower curves for a #8 and #10 blade to extrapolate the fan BHP at 5,700 SCFM halfway between these 2 HP curves gives 20HP. Per Reference 5.10 and 5.36, the SBV fan serial number is SF 27913. Reference 5.10 states that the motor with this serial number is 25 HP, thus the SBV fan motor is sufficient for the recommended design flow rate of 5,700 SCFM.
7.0 CONCLUSION
S AND RECOMMENDATIONS 7.1
SUMMARY
OF RESULTS 7.1.1 FLOW RESULTS The proper design flow rate of the SBV system has been determined to be 5,700 SCFM based on the PROTO-HVAC analysis and system test data. 5,700 SCFM is acceptable for the filter flow rate as it is within the acceptable range given in Design Input 3.1.5. It is also within the acceptable range for SBV fan flow that is given in References 5.33 and 5.34 of 4,500 and 6,600 CFM. 5,700 SCFM is below the flow rate of 6,000 SCFM used in Reference 5.2, so this reference will need to be evaluated to determine the impact of this lower flow on the Reference 5.2 analysis.
7.1.2 FILTER PRESSURE DROP RESULTS The technical specification for the SBV filter units states that the pressure drop across the combined REPA filters and charcoal adsorber banks must be less than 10" WG and must be less than 4" WG across any HEPA filter bank. at the system design flow rate (+/- 10%). The fan static pressure for the no-flow condition is 11" WG, as determined from Reference 5.9, and the filter components must be able to withstand this pressure. The pressure at the no-flow condition is less than the maximum fan total pressure of 14.5" WG which occurs at approximately 4,500 SCFM.

These files are suitable for use with flow rates above 4,500 SCFM as discussed in section 4.0. The results in this calculation are valid for the as-modeled configuration which was benchmarked to test data.

7.3 ACCEPTANCE CRITERIA 7.3.1 The system flow rate for the SBV filter conditions should not exceed 6,600 SCFM per Design Input 3.1.5. The recommended system design flow rate of 5,700 SCFM is below this value, as are all calculated and test data flow rates.
7.3.2 The maximum allowed filter DPs should not exceed the vendor recommended pressure drop values given. Table 9 shows that the calculated maximum allowable filter DPs at the minimum allowable system flow are below the vendor recommended values.
7.4 00ACT TO SYSlEMS, SlRUCTURES AND COMPONENTS This calculation impacts the Shield Building Ventilation System filter maximum DP.
Documents impacted by this change are listed in section 7.14.
7.5 CONSERVATIVENESS OF CALCULATION AND AVAILABLE MARGIN The calculation is conservative since it uses minimum allowable flow rates when calculating pressure drops. Based on the margin values calculated in Table 9, the filter component with the lowest margin available is the Train A prefilter, with a margin of 0.163" WO.
7.6 UNCERTAINTY OF RESULTS An uncertainty analysis was not performed for this calculation. Uncertainty may either be covered in the licensing basis or calculated in another calculation if needed in the future.
7.7 CONSISlENCY wrrn DESIGN AND OPERATION OF PLANT There is currently an inconsistency between plant operation and the SBV system design flow rate. The SBV System Design Flow is listed differently in different documents as described in section 2.0 and the SBV test data flow rates show different values. The results of this calculation resolve this discrepancy by recommending a system design flow rate. This will also resolve CA081875 (CR106464) which addresses the issue of the different flow rate values.

7.10 OPEN ITEMS (NEW OR CLOSURE)
This calculation will resolve CA081875 (CRI06464) and CA).28813 (CR323062). CA081875 addresses the discrepancies in SBV flow rate among the fan acceptance criteria given in SP-24..
122A&B, filter design flow rate, and flow rate used in calculation CN-CRA-00-2. The results of this calculation show that the actual S~V flow rate is 5,700 SCFM. To resolve the discrepancy in flow rates, the SBV system design flow rate should be changed to 5,700 SCFM. This flow rate is within the range of the fan flow acceptance criteria. Reference 5.23 shows that 5,700 SCFM is an acceptable flow rate for the system filters. A new corrective action will need to be initiated to revise CN-CRA-00-2 as recommended in CA081875 since the 6,000 SCFM used in CN-CRA-OO-2 will need to be changed to 5,700 SCFM. A procedure change as recommended in CA081875 will need to be initiated for SP-24-122A and SP-24-122B to change the maximum DP values listed for the filters and the allowable flow rates.
CA128813 calls for calculation 12123 to be revised to detennine the maximum allowed DP for the REPA and charcoal filters. The maximum allowed DPs for these components have been detennined and are presented in Table 9. The results in this table may be used to initiate a follow-on to revise tech spec 4.4.c.1.a as indicated in CA128813.
7.11 REASONABLE ASSURANCE OF SAFETY There are no reasonable assurance of safety (RAS) issues associated with this calculation since RASs generally do not apply to the SBV system as it is tech spec equipment, per Reference 5.31.
7.12 SUPERSEDED CALCULATIONS This calculation supersedes Revision 0 of calculation 12123 and calculation 1171.M3.
7.13 lMPAClED CALCULATIONS Calculation CN-CRA-00-2 is impacted since the SBV flow rate used in that calculation is 6,000 SCFM and this calculation changes the SBV system flow rate to 5,700 SCFM. Based on a review of the Dominion Portal, this calculation does not impact any other calculations.

The results of this calculation may be used to resolve CA081875 (CRI06464) and CA128813 (CR323062). Procedure SP-24-107C, SP-24-107D, SP-24-122A and SP-24-122B may require updates. Drawings M-602, OPERM-602 and XK-300-2 may require updates.
7.15 ANOMALIES The fan curve in the PROTO-HVAC model does not match the actual fan curve for values below 4,500 SCFM. This was done to allow the PROTO-HVAC model to converge as discussed in section 4.0 and does not affect the accuracy of the calculation since the flow rates herein are above 4,500 SCFM. If this PROTO-HVAC model is used for SBV flow rates below 4,500 SCFM the fan curve will have to be modified to give accurate results.
7.16 EFFECTIVENESS OF CALCULATION The purpose of the calculation has been met.
