U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 1 of 47 REQUEST FOR ADDITIONAL INFORMATION RAI 2.3-01 General Items
Background:
Title 10 of the Code of FederalRegulations (10 CFR) 54.4(a) provides criteria for determining whether systems or components are in scope for license renewal.
Issue: Sections of the Crystal River Unit 3 Nuclear Generating Plant (CR-3) license renewal application (LRA) indicate that parts of various systems are in scope because they contain components that are relied upon during postulated fires per 10 CFR 54.4(a)(3). Section 2.1 of the CR-3 LRA describes the process for selecting components that are in scope under 10 CFR 54.4(a)(3). However, numerous systems identified with components that are included in scope under 10 CFR 54.4(a)(3) to operate during postulated fires contain no discussion of the (a)(3) components in the CR-3 LRA system description text, the CR-3 final safety analysis report (FSAR) discussion, or on the CR-3 LRA drawings provided. It is not possible to identify components that are included in scope under 10 CFR 54.4(a)(3) for components that are relied upon during postulated fires without an understanding of the components that were selected by the process. Specific examples of systems with components that are not identified within scope under 10 CFR 54.4(a)(3) include:
- 2.3.3.25 Circulating Water System
- 2.3.3.28 Fuel Oil System 0 2.3.3.32 Demineralized Water System
- 2.3.3.38 Instrument Air System
- 2.3.3.42 Make Up and Purification System
- 2.3.4.3 Condensate Chemical Treatment System
- 2.3.4.4 Condensate System
- 2.3.4.18 Secondary Plant System Request: Provide sufficient information to permit the staff to identify all portions of the systems within the license renewal boundary as specified in 10 CFR Section 54.4(a)(3).
Response
Consistent with the methodology utilized in previous Progress Energy License Renewal Applications (LRA), the CR-3 scoping process for 10 CFR 54.4(a)(3) was based on a review of component level data in the Passport Equipment Database (EDB), supplemented by topical reviews as necessary, to ensure a comprehensive result. CR-3 utilizes the EDB to maintain the licensing basis for regulated events by translatingcompliance requirements in plant design and licensing basis documents into component level parameters.
The EDB provides individual component parameters associated with compliance with Station Blackout (SBO), Fire Protection (FP), Anticipated Transients Without Scram (ATWS), and Environmental Qualification (EQ) requirements. Fire Protection parameters can be further broken down into Appendix R and classical fire protection, and within classical fire protection, a separate EDB parameteris also assigned to credited fire barrierpenetrations. CR-3 considered
U. S. Nuclear Regulatory Commission Enclosure 3F17109-05 Page 2 of 47 that components credited in the EDB for regulated events are in License Renewal scope.
Likewise, systems containing credited components are in scope, with the associated system intended function being compliance with the applicable regulatedevent(s).
The mechanical systems identified in Table 2.2-1 of the CR-3 LRA also include electrical and civil components that are credited in licensing evaluations for compliance with 54.4(a)(3) events.
Since scoping was done on a system basis, these civil and electrical components are subject to scoping as part of the system they are assigned to in the EDB, and their scoping results are reflected in the resulting list of system intended functions presented in the LRA. A review of scoping results for the examples given in this RAI shows that 54.4(a)(3) scoping for each of these systems was coupled to electrical and civil components that do not appear on License Renewal boundary drawings, and that most of these systems have no mechanical components or mechanical intended function associated with 54.4(a)(3) scoping. For example, the Condensate Chemical Treatment, Condensate, Circulating Water, Demineralized Water, Instrument Air, and Makeup & Purification Systems all have fire barrierseals (a civil feature) associated with the 54.4(a)(3) system intended function for Fire Protection. Generally, where 54.4(a)(3) scoping is associatedwith a mechanical intended function, the function is not unique to the regulated events involved, and is encompassed by the system descriptions provided in Section 2.3 of the CR-3 LRA. The following table addresses the 54.4(a)(3) scoping basis for the examples presented in this RAI.

RAI 2.3-02 General Items
Background:
10 CFR 54.21(a)(1) requires the applicant to provide a list of structures and components subject to an aging management review (AMR). The staff reviews the LRA, FSAR, and license renewal boundary drawings to verify that the list of components provided for each system is complete.
Issue: The CR-3 LRA does not specify which version of the FSAR is to be used as a reference. The last revision of the FSAR submitted to the NRC was Revision 30.
Subsequently, a complete copy of Revision 31 of the CR-3 FSAR was provided following the June 2009 NRC site audit. As a result of the June 2009 NRC site audit, it was determined that most of the calculations for the CR-3 LRA were performed using CR-3 FSAR Revision 30.
Request: Provide revisions to the FSAR that would affect any systems within the scope of license renewal since Revision 30.
Response
The CR-3 LRA was submitted to the NRC by letter dated December 16, 2008. The Final Safety Analysis Report (FSAR) revision submitted to the NRC, and in effect at the time of the LRA submittal, was Revision 31. FSAR Revision 31 was submitted by CR-3 to NRC letter, 3F0508-13, dated May 28, 2008, "CrystalRiver Unit 3 - Final Safety Analysis Report, Revision 31 and 10 CFR 50.59 Report." Copies of FSAR Revision 31, on CD format, were provided during the June 2009 audit as an aid to the NRC auditors.
Regardless of the FSAR revision that was in effect during preparation of the basis documents (i.e., the calculations) that support the LRA, the technical informnation supporting the LRA was reviewed and updated prior to submittal of the LRA. In addition, the basis documents supportingthe LRA were updated as necessary to reflect the results of this review.
The next revision of the FSAR will be submitted following the current refueling outage at CR-3 in accordance with 10 CFR 50.71(e). Future changes to the Current Licensing Basis that materially affect the contents of the LRA will be provided to the NRC in accordance with 10 CFR 54.21(b).
U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 4 of 47 RAI 2.3-03 General Items Backqround: 10 CFR Section 54.21(a)(1) requires applicants to identify and list components subject to an AMR. The staff confirms inclusion of all components subject to an AMR by reviewing the components within the license renewal boundary.
Issue: During the scoping and screening review process, the continuation from one drawing to another could not be established. Drawing numbers and/or locations for continuations were not identified and could not be located where identified, the continuation drawing was not provided, and piping expected to be in scope based on one drawing led to a different conclusion on a connecting drawing.
Given below is a table that indicates the systems identified with these drawing inconsistencies.
License Renewal Continuation Location / Issue Application (LRA)
Section/Drawing Number 2.3.3.24 INDUSTRIAL COOLING SYSTEM Four feedwater (FW) system relief valves are shown at locations E-4 (connected to CIHE-2A and 2B), F-3 (near CIV-279), and G-3 (near CIV-280). The relief LRA.302..762-LR, SH01 line from each of these valves is shown to be within scope of the license renewal. However, the lines from these four valves are not continued on another CR-3 LRA drawing, nor do they terminate at another valve or structure.
2.3.3.26 EFP-3 DIESEL AIR STARTING SYSTEM Two lines connected to two solenoid operators in locations C-6 and E-6 are highlighted in scope for LRA-302-778-LR, SH01 license renewal. However they are not continued on another CR-3 LRA drawing, nor do they terminate at another valve or structure.
The drawing depicts four lines to the building sump pump as included in scope of license renewal under 10 CFR 54.4(a)(1). The connecting drawing is not noted. Therefore, it is not possible to evaluate the LRA-302-778-LR, SH01 interaction of the sump pump piping on the EFP-3 diesel air starting system. CR-3 LRA drawing 302-114-LR, SH02, depicts an EFP area sump, but it is not clear if this is the building sump referenced on CR-3 LRA drawing 302-778-LR, SH01.
U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 5 of 47 2.3.3.27 DECAY HEAT CLOSED CYCLE COOLING SYSTEM Relief valves are shown in structures that contain 10 CFR 54.4(a)(1)components. The discharge path of these relief valves is not indicated. An example of this on the referenced drawing occurs at locations LRA-302-631-LR, SH01 E-3, C-7, D-8, D-9, and B-10. However, similar relief valves appear in numerous system drawings. Identify the relief path from the relief valves for all systems inside structures that contain 10 CFR 54.4(a)(1) components so that spatial interaction can be evaluated.
2.3.3.29 JACKET COOLING SYSTEM The drawing depicts a pipe line marked 300-1 (shown at D-9 on each drawing) as included in scope of LRA-302-283-LR, license renewal under 10 CFR 54.4(a)(1). This pipe SH01A&302-SH01 &02 has an unidentified continuation arrow. Without

further information on this interface, it is not possible to evaluate the interaction of the connected piping on the jacket coolant system.
2.3.3.32 DEMINERALIZED WATER SYSTEM At F-8, the drawing identifies connected piping in the liquid waste disposal spent resin transfer system at the decant pump suction as included in scope of LRA-302-182-LR, SH01 license renewal under 10 CFR 54.4(a)(2). The associated drawing, 302-681-LR, SH05 does not identify any piping in scope at the decant pump suction.
At C-4, the drawing identifies connected piping in the liquid waste disposal reactor coolant subsystem at the deborating demineralizers as included in scope of license renewal under 10 CFR 54.4(a)(2). The associated drawing, 302-681-LR, SH03 identifies this connection as the boundary to an area exclusion where spatial interaction concerns do not exist.
Therefore, there is a conflict as to what the applicant is identifying as in scope and what is excluded.
U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 6 of 47 2.3.3.38 INSTRUMENT AIR SYSTEM The drawing depicts the backup air system for automatic dump valves (ADVs) as in scope of license renewal under 10 CFR 54.4(a)(2). Continuation arrows are depicted in the intermediate building to MSV-25 and MSV-26. However the various air piping to the ADVs is not depicted on any instrument air LRA-302-271-LR, SH01 system drawing or on the main steam drawings.
Without a more extensive discussion of the instrument air piping to MSV-25 and MSV-26, it is not possible to validate that all components associated with the backup air system have been included in scope and evaluated for inclusion in an aging management program (AMP).
No connection is shown from the instrument air system to the backup air system. A connection through IAV-546 and IAV-548 was expected.
The drawing depicts an unlabeled drawing continuation mark as in scope of license renewal under 10 CFR 54.4(a)(2) at drawing location E-2.
The CR-3 FSAR, Rev 31, drawing shows this connection to the condensate demineralizer system.
This reference is not included with the license renewal drawings.
The drawing inconsistently depicts American Society of Mechanical EngineersSection III, Class 2 and Class 4 flags on either side of containment penetrations 111 and 112 at location C-9. The depicted labeling confuses the evaluation of the boundaries for 10 CFR 54.4(a)(1) and (a)(2) piping and piping components.
2.3.3.41 MISCELLANEOUS DRAINS SYSTEM The drawing depicts a pipe continuation to a drain as in scope of license renewal at drawing location H-4. It is not clear if this continuation depicts a pipe run or an opening to another drain sump. No boundary flag is depicted. It is not possible to completely evaluate piping that may be in scope of license renewal for spatial interaction without further discussion.
U.'S. Nuclear Regulatory Commission Enclosure 3F1109-05 Page 7 of 47 2.3.3.49 NUCLEAR SERVICE AND DECAY HEAT SEA WATER SYSTEM The line leaving valve RWV-1 11 shown at location F-6 is shown to be within the scope of license LRA-302-611-LR, SH01 renewal. However, it is not continued on another CR-3 LRA drawing, nor is it terminated at another valve or structure.
The discharge lines from RWV-61 (at location E-3) and RWV-62 (at location E-4) are shown to be within the scope of license renewal. However, the lines from these two valves are not continued on another CR-3 LRA drawing, nor do they terminate at another valve or structure.
2.3.3.50 STATION AIR SYSTEM The drawing depicts connections to fire service valves (FSV-1 145, FSV-1 146, and FSV-1 147) as in LRA-302-271-LR, SH09 scope for license renewal. No connecting piping is depicted for a continued scoping and spatial interaction evaluation.
2.3.3.52 STATION DRAINS SYSTEM The line coming into isolation valve SDV-133 at location G-7 is shown to be within the scope of LRA-302-113-LR, SH02 license renewal. However, it is not continued on another CR-3 LRA drawing, nor is it terminated at another valve or structure.
Instrument air supply to SDV-90 shown at location A-8 is shown to be within the scope of license LRA-302-163-LR, SH01 renewal. However, the line into this valve is not continued on another CR-3 LRA drawing, nor is it terminated at another valve or structure.
2.3.3.60 WASTE SAMPLING SYSTEM The air supply line to flow control, RM-A6-FC, at location G-5 is shown to be within the scope of LRA-302-693-LR, SH01 license renewal. However, it is not continued on another CR-3 LRA drawing, nor is it terminated at another valve or structure.

U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 8 of 47 2.3.4.1 CONDENSER AIR REMOVAL SYSTEM At location G-3, the applicant shows a line that goes into valve ARV-164. The drawing indicates that this LRA-302-131-LR, SH01 line is within the scope of AMR, but it does not indicate where the line originates from or to what the line connects.
2.3.4.4 CONDENSATE SYSTEM Locations B-4 and B-9 show an exhaust line from the main feedwater pumps turbines (FWTB-1A at location B-4, FWTB-1 B at location B-9) to an open area of the drawing. These exhaust lines are also labeled "By LRA-302-101-LR, SH01 Foster Wheeler Corp." However, it is not clear if the FWTB exhaust to the atmosphere within theturbine building or to some other component or heat sink.
Also, these two lines show no visible means of support or anchor.
2.3.4.10 MAIN FEEDWATER SYSTEM Four FW system relief valves are shown at locations B-1 (FWV-263), B-2 (FWV-262), D-2 (FWV-16), and D-3 (FWV-17). The relief line from each of these LRA-302-081-LR SH02 valves is shown to be within scope of the license renewal. However, the lines from these four valves are not continued on another CR-3 LRA drawing, nor do they terminate at another valve or structure.
Two FW system relief valves are shown at locations D-7 (FWV-4) and D-9 (FWV-3). However, the relief line from each of these valves (FWV-3 & -4) are not shown on the drawing. Also, the lines are not continued on another CR-3 LRA drawing, nor do they terminate at another valve or structure.
Request: Provide sufficient information for the continuation issues identified above to permit the staff to review all portions of the systems within the license renewal boundary as specified in 10 CFR Section 54.21(a)(1).
Response
CR-3 flow diagrams often do not depict, in their entirety, all relief valve discharge piping, instrument air piping to point of use devices, sample piping/tubing and drain piping. These piping components are included in scope in Class I structures. In addition, CR-3 has revised its methodology for spatial interactionscoping to be more inclusive than the original LRA submittal scope as discussed in the response to RAI 2.1-2 in CR-3 to NRC letter, 3F0909-04, "Crystal

Background:
10 CFR Section 54.21 (a)(1) requires applicants to identify and list components subject to an AMR. The staff confirms inclusion of all components subject to an AMR by reviewing the components within the license renewal boundary.
Issue: During the scoping and screening review process, several structures were found on the CR-3 LRA drawings that were not included within the scope of license renewal. These structures were sumps, waste collectors, canals, pits, etc. In the table below it is indicated which systems are associated with these structures.

Background:
10 CFR Section 54.21 (a)(1) requires applicants to identify and list components subject to an AMR. The staff confirms inclusion of all components subject to an AMR by reviewing the components within the license renewal boundary.
Issue: The applicant used a definition for piping, piping components, and piping elements that are based on Section IX of NUREG-1801, Volume 2. The CR-3 definition of "Piping, piping components, and piping elements" replaces various combinations of the following: piping, fittings, tubing, flow elements/indicators,
-filter/demineralizer housings, nozzles, orifices, flex hoses, expansion joints, pump casing and bowl, safe ends, sight glasses, spray head body, strainer housings, thermowells, valve body and bonnet, and closure bolting. However, in the LRA, components such as expansion joints, filters, strainers, and flexible connections are specifically identified in the AMR for one or more mechanical systems, but not the associated, tables for other similar mechanical systems.
Also, components that have an intended function in addition to M-1, pressure boundary, such as M-2, filtration, and M-5, heat transfer, are frequently not listed separately with the additional intended function. Rather, these components are frequently only listed under piping components with an M-1 function.
Furthermore, some systems list tanks with piping and some systems list tanks separately. The staff is unable to discern a consistent CR-3 methodology for identifying components on the mechanical system AMR tables in the Scoping and Screening Results-Mechanical Systems section of the CR-3 LRA.
Consequently, the staff is unable to verify that all components subject to an AMR are adequately represented in the AMR tables. Given below is a table with examples of systems identified with these table inconsistencies.

This tank is a significant system component and the tank is not specifically included on Table 2.3.3-32 or Table 3.3.2-32 with intended function M-1, pressure boundary. Other systems, such as the fuel oil system, identify significant system tanks that are subject to an AMP separately.
The drawing depicts the post treatment filter as included in scope of license renewal under 10 CFR 54.4(a)(2) at the discharge of demineralized water pumps DWP-1A and DWP-1 B (shown at D-7 on the drawing). The filter is not included on Table 2.3.3-32 or Table 3.3.2-32 with intended function M-2, filtration.
2.3.3.33 EMERGENCY DIESEL GENERATOR SYSTEM Filters are depicted as included in scope of license renewal under 10 CFR 54.4(a)(1) in numerous system drawings. An example of this on the referenced drawing occurs at locations D-1 and D-8. However, similar filters appear in numerous LRA-302-282-LR, SH01 system drawings, and the filters are not specifically included on Table 2.3.3-33 nor Table 3.3.2-33 with intended function M-1, pressure boundary or M-2, filtration. Filters do not appear to meet the CR-3 definition for piping, piping components and piping elements.

Nuclear Regulatory Commission Enclosure 3F1109-05 Page 35 of 47 The drawing depicts flexible connections in the drawing as included in scope of license renewal under 10 CFR 54.4(a)(1) at locations E-1 (near EGV-35) and E-8 (near EGV-39). These components are not included on Table 2.3.3-33 or Table 3.3.2,33 with intended function M-1, pressure boundary.
2.3.3.41 MISCELLANEOUS DRAINS SYSTEM The drawing depicts a flash tank as in scope of license renewal at drawing location H-3. Typically, a pressure and temperature change allows entrained steam in the drains to change state to LRA-302-114-LR, SH02 liquid and cool in the flash tank. Table 2.3.3-41 and Table 3.3.2-41 in the LRA only identify components with an intended function of pressure-boundary (M-1). The flash tank is not identified with an intended function of heat transfer (M-5).
2.3.3.42 MAKE UP AND PURIFICATION SYSTEM The drawing depicts Y-strainers as in scope of license renewal at drawing locations E-3 and E-7.
These components are not included on Table 2.3.3-42 or Table 3.3.2-42 with intended function LRA-302-661-LR, SH01 M-2, filtration. Strainers are identified in other systems such as the nuclear services closed cycle cooling system. The applicant should identify Y-strainers in all systems and verify that they are included in an AMP.
2.3.3.49 NUCLEAR SERVICE AND DECAY HEAT SEA WATER SYSTEM Expansion joint encapsulation sleeves, RWEJ-1 through RWEJ-10, shown at locations F-2, D-2, LRA-302-611-LR, SH01 F-10, D-9, E-9, D-8, E-8, D-7, E-7 and D-6, respectively, are not specifically included in Tables 2.3.3-49 or 3.3.2-49.
Request: Explain the CR-3 methodology for identifying components on the mechanical system aging management program tables in the scoping and screening results-mechanical systems section of the CR-3 LRA. Justify the exclusion of the listed components with a specific intended function from an AMR. Evaluate all systems for similar excluded components.

Response
NEI 95-10, Section 4.1, discusses that it may be beneficial to create commodity groups of like structures or components to disposition the entire group with a single aging management review. The basis for group structures or components can be such characteristicsas similar design, similar materials of construction, similar aging management practices and similar environments. The Structure and Component Screening process described in Section 2.1.2 of the CR-3 LRA states:
During the screening process, some SCs were incorporated into commodity groups based on similarity of their design or materials of construction. Use of commodity groups made it possible to address an entire group of SCs with a single evaluation. This approach is consistent with the changes made in Revision 1 of NUREG-1801, "Generic Aging Lessons Learned (GALL) Report" to enhance. its applicability to future plant License Renewal applications. One of these revisions was the simplification and generalization of terms used to make the component/commodity line items more generic and less prescriptive. As an example based on the definitions in Section IX of NUREG-1801, Volume 2, the CR-3 definition of "Piping,piping components, and piping elements" replaces various combinations of the following: piping, fittings, tubing, flow elements/indicators, filter/demineralizer housings, nozzles, orifices, flex hoses, expansion joints, pump casing and bowl, safe ends, sight glasses, spray head body, strainerhousings, thermowells, valve body and bonnet, and closure bolting.
As with the definition in GALL, Volume 2,Section IX, the list of component types associatedwith the definition of "piping,piping components, and piping elements" in Section 2.1.2 of the CR-3 LRA was not intended to be prescriptive. Consistent with the methodology recently used and accepted in the Harris Nuclear Plant License Renewal Application, CR-3 utilizes this term to generically address piping system components whose sole component intended function is to provide a pressure boundary. In some cases, components are included that potentially have multiple intended functions, but for the application at hand, have only the "M-1" pressure boundary function. Common examples are found in systems that are only in scope for potential spatial interaction with safety related components. The intended function for components in these systems would be to maintain their pressure boundary so as not to leak; and component level functions for straining/filtration,heat transfer, and flow restriction would not apply. Under this circumstance, the line item "Piping,piping components, and piping elements" would be expanded to include strainer/flow element housings and heat exchanger shells, as applicable.
Deference was given to systems having small miscellaneous tanks (expansion chambers, accumulators, etc.) to use the GALL variant "Piping,piping components, piping elements and tanks" to reflect the presence of these components.
It is important to note that the term "Piping,piping components, and piping elements" was only used to generically represent piping components having the M-1 intended function.
Components/commodities having other component intended functions were broken out into separate line items and associated with the applicable component intended function(s). CR-3 did provide separate listings of major system components to improve in accounting during the review process. The intent was to account for system components consistent with the extent reflected in NUREG-1801 Volume 1 and Volume 2 AMR tables, with additional consideration given to providing line items identifying major system pumps, tanks, and heat exchangers as an aid to reviewers.
The following table resolves scoping results for the individual examples provided in this RAI:

Background:
10 CFR Section 54.21 (a)(1) requires each applicant to describe and justify the methods used to identify and list those structures and components subject to an AMR.
Issue: The LRA includes the control complex chiller lube oil pumps and oil cooler tubes in an AMR. These components are not shown on CR-3 LRA drawing 302-756-LR, SH01. Without a drawing or a more extensive discussion of the system components, it is not possible to validate that all components associated with the lube oil system have been included in scope and evaluated for inclusion in an AMR.
Request: Provide supplemental information for staff to verify that all control complex chilled water lube oil components are included in scope of license renewal under 10 CFR Section 54.21 (a)(1) and evaluated for an AMP.
Response
The CR-3 Control Complex Chiller lubrication system consists of the lubrication oil pumps, oil filter, oil cooler, and interconnectingpiping. These skid mounted components are not depicted on CR-3 flow diagrams. The oil cooler has no shell, but ratherthe tubes transfer heat directly to the refrigerant in the refrigerant reservoir. The lubrication oil filter is a cartridge filter that is replaced regularly, and the short-lived filter cartridge is not subject to aging management. As such, aging management requirements for the lubrication system are limited to the piping system pressure boundary (M-1) function, and the heat transfer (M-5) function for the lube oil cooler tubes. The Control Complex Chiller Lube Oil Pumps and Control Complex Chiller Oil Cooler Tubes are identified individually in component/commodity line items in LRA Table 2.3.3-
- 22. Lube oil piping components having the M-1 intended function, including the oil filter housing, are included in "Piping,piping components, and piping elements."
RAI 2.3.3.27-01 Decay Heat Closed Cycle Cooling System

Response
Valves DCV-212 and DCV-213 are in the scope of license renewal for 10 CFR 54.4(a)(2), and should have been highlighted on their respective LRA drawings. These valves are represented within "Piping,piping components, and piping elements" in Table 2.3.3-27.
RAI 2.3.3.32-01 Demineralized Water System
Background:
10 CFR Section 54.21(a)(1) requires applicants to identify and list components subject to an AMR. The staff confirms inclusion of all components subject to an AMR by reviewing the components within the license renewal boundary.
Issue: On CR-3 LRA drawing 302-182-LR, SH01, the drawing identifies numerous area exclusions where spatial interaction concerns do not exist. In the CR-3 LRA, the applicant states that "...non-safety related piping (including air/gas systems) and ducting components located inside seismic Class I structures have been conservatively included in scope unless specific evaluations were performed to justify exclusion." However, the demineralized water system area exclusions are not described in any detail in the CR-3 LRA. Without a more extensive discussion of these area exclusions, it is not possible to validate that all components associated with the demineralized water system have been included in scope and evaluated for inclusion in an AMP.
Request: Provide justification for excluding the component types from the scope of license renewal to permit the staff to identify all portions of the systems within the license renewal boundary as specified in 10 CFR 54.21 (a)(1).
Response
CR-3 has revised its methodology for spatial interaction scoping to narrowly permit exclusions only in areas where there are no safety related components, that are adequately protected and isolated from other areas of the plant, and are equipped with drain systems which are themselves in the scope of license renewal (See RAI 2.1-2 response in CR-3 to NRC letter, 3F0909-04, "Crystal River Unit 3 - Response to Requests for Additional Information for the Review of the Crystal River Unit 3 Nuclear GeneratingPlant, License Renewal Application (TAC NO. ME0274)," dated September 18, 2009 (ML092650272)). Based on these criteria, spatial interaction scoping exclusions associated with the Demineralized Water System are limited to three demineralized water supply valves (DWV-235, DWV-237, and DWV-238) and associated piping located in the Radwaste Processing Area of the AB. The balance of Demineralized Water System piping components located inside Seismic Class 1 Structures has been included in License Renewal scope. These components are represented by the component/commodity group "Piping,piping components, piping elements, and tanks"in Table 2.3.3-32.
RAI 2.3.3.38-01 Instrument Air System
Background:
10 CFR Section 54.21(a)(1) requires applicants to identify and list components subject to an AMR. The staff confirms inclusion of all components subject to an AMR by reviewing the components within the license renewal boundary.
U. S. Nuclear Regulatory Commission Enclosure 3F1109-05 Page 42 of 47 Issue: On CR-3 LRA drawing 302-271-LR, SH01, the drawing depicts the backup air system for ADVs as in scope of license renewal under 10 CFR 54.4(a)(2) for the instrument air system. However, in LRA Section 2.3.4.16, Main Steam System, the applicant identified the following two 10 CFR 54.4(a)(1) functions for the main steam system:
The system provides relief capacity to protect the steam generators from overpressurization for a loss of electric power.
The system controls steam generator pressure and thereby provides a mechanism for controlled decay heat removal for a loss of electrical power, steam line failure, loss of coolant accident, feedwater line break, and steam generator tube failure.
The ADV support of the 10 CFR 54.4(a)(1) functions of the main steam system would seem to indicate that the backup air system should be included as in scope of license renewal under 10 CFR 54.4(a)(1). It follows that equipment in the turbine building may be included as in scope of license renewal under 10 CFR 54.4(a)(2), nonsafety related components that could potentially affect the function of 10 CFR 54.4(a)(1) components.
Request: Justify the exclusion of the backup air system as within scope of license renewal under 10 CFR 54.4 (a)(1).
Response
FSAR Section 10.2.1.4 discusses the atmospheric dump valves (ADVs) and states that the atmospheric dump valve relief capacity or control functions are not required to mitigate any limiting FSAR accident. The backup bottled air system for the ADVs provides a backup source of motive power to comply with the operability requirements for the coping period following a Station Blackout (SBO), which is a 10 CFR 54.4 (a)(3) function.
RAI 2.3.3.38-02 Instrument Air System
Background:
10 CFR 54.21(a)(1) requires applicants to identify and list all SSCs subject to an AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: In the response letter to NRC request for additional information, dated May 11, 2009, the applicant provided 10 CFR 54.4(a)(1)and (a)(2) functions for LRA systems. In the instrument air system, the applicant identified an 10 CFR 54.4(a)(1) function that indicates the system contains components associated with air reservoirs that provide an assured source of air to various safety related components. However, the main instrument air receivers were identified on the CR-3 LRA drawings 302-271-LR, SH01 and SH02. No individual component air reservoirs were identified on the drawings or included in the AMR tables for the instrument air system.
- U. S. Nuclear Regulatory Commission Enclosure 3F1109-05 Page 43 of 47 Request: Provide an explanation on why individual air reservoirs were excluded from being in scope of license renewal under 10 CFR 54.4(a).
Response
Individual air reservoirs were not excluded from the scope of License Renewal. The referenced air receivers are small passive tanks and are included in the scope of License Renewal in the Air Handling Ventilation and Cooling System, Control Complex Ventilation System, Industrial Cooling System, Circulating Water System, Main Feedwater System, Main Steam System, Make Up & Purification System, Secondary Services Closed Cycle Cooling System, and the Nuclear Services Closed Cycle Cooling System. As an example, the subject Main Steam System air receivers are in scope, and included in LRA Table 2.3.4-12 as "Piping, piping components, piping elements, and tanks."
RAI 2.3.3.52-01 Station Drains System
Background:
10 CFR 54.4(a) requires applicants to identify and list all SSCs subject to an AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: On CR-3 LRA drawing 302-281-LR, SH01, the drawing shows two "2" to Nearest Floor Drain" lines at locations E-3 and E-6. These lines appear to exit the building through a dividing wall and are shown to be within the scope of license renewal. If these lines are fluid-filled and go to the auxiliary building they can affect a safety-related component if they break.
Request: Describe where these lines go, and if any additional components should be included in the scope of license renewal.
Response
The two 2 in. lines routed to the nearest floor drains, shown at locations E-3 and E-6 on drawing 302-281-LR, SH01, exit the Diesel GeneratorBuilding into the Clean Maintenance Shop.
The portion of these lines that are within the Diesel GeneratorBuilding are included in the scope of License Renewal. These piping components are included in LRA Table 2.3.3-52 as "Piping, piping components, and piping elements,"
RAI 2.3.3.53-01 Spent Fuel Cooling System
Background:
10 CFR 54.21(a)(1) requires applicants to identify and list all SSCs subject to AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: On CR-3 LRA drawing 302-621-LR, SH01, the drawing indicates two heat exchangers in the spent fuel storage pools "A" and "B" that are not included in the scope of license renewal. Heat exchanger FHX-2 is shown at location B-6 and heat exchanger FHX-3 is shown at location B-9.
U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 44 of 47 Request: Provide the function of these heat exchangers and justify their exclusion from being in scope of license renewal under 10 CFR 54.4(a).
Response
Tag numbers FHX-2 and FHX-3 are not heat exchangers, but fuel pool gates, as denoted by the term "Gate"immediately over FHX-2.
RAI 2.3.4.3-01 Condensate Chemical Treatment System
Background:
10 CFR 54.21 (a)(1) requires applicants to identify and list all SSCs subject to an AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: LRA Section 2.3.4.3, states that the condensate chemical treatment system is located within the turbine building, but has components in scope under 10 CFR 54.4 (a)(2), because the system has non-safety related components whose failure could prevent satisfactory accomplishment of the safety related functions.
However, LRA Section 2.4.2.18, states that the turbine contains only non safety-related components.
The hydrazine addition tank is part of the chemical treatment system. LRA Figure 2.2-1 indicates that the hydrazine addition tank is within the scope of license renewal; however, 'tank' is not included as mechanical component type in the scope of license renewal. Yet, LRA Section 2.4.2.15, Miscellaneous Structures, describes the hydrazine addition tank foundation as being within the scope of license renewal because of a calculation for non-safety affecting safety identified the tank as required to support a design basis event.
Request: Provide an explanation for why the hydrazine tank foundation was included in the scope of license renewal for possible interaction with safety-related components; indicate which safety-related component interacts with the hydrazine addition tank, and provide justification of the exclusion of the hydrazine addition tank on the foundation from the scope of license renewal.
Response
The Hydrazine Batch Tank, referred to in LRA Section 2.3.4.3, is in the Condensate Chemical Treatment System, and is not in the scope of License Renewal. The Hydrazine Addition Tank is part of the Condensate System and is included in LRA Table 2.3.4-3 as "Piping, piping components, piping elements, and tanks." The Hydrazine Addition Tank is not adjacent to any Class I structure and is therefore not a seismic interaction concern. The topical calculationfor 10 CFR 54.4(a)(2) scoping identified the Condensate System as a non-safety related system necessary to support main condenser vacuum during a steam generator tube rupture event. The Hydrazine Addition Tank was included in scope for 10 CFR 54.4(a)(2) as part of the Condensate System. As such, the Hydrazine Addition Tank foundation is within the scope of License Renewal.
U. S. Nuclear Regulatory Commission Enclosure 3F1109-05 Page 45 of 47 RAI 2.3.4.3-02 Condensate Chemical Treatment System
Background:
10 CFR 54.21 (a) requires applicants to identify and list all SSCs subject to an AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: The LRA stated the 10 CFR 54.4(a)(2) function for this system describes pressure boundary seals that support the control complex habitability envelope.
The seals are also considered to be civil components. The LRA does not contain any AMR tables listing mechanical components for the chemical treatment system, but does indicate that there are civil and electrical components in this system that are in scope for license renewal. The LRA does not provide details on what type of components (mechanical or electrical) are associated with these pressure boundary seals.
Request: Identify the components transitioning through these seals; and if they are liquid filled, then justify their exclusion from the scope of license renewal under 10 CFR 54.4(a)(2). Also, identify the LRA table depicting the AMR for these pressure boundary seals.
Response
The Condensate Chemical Treatment System includes three in-scope civil discipline fire barrier penetration seals located in the control complex. These fire barrierpenetration seals are age-managed as identified in LRA Table 3.5.2-6, Containments, Structures, and Component Supports - Summary of Aging Management Evaluation - Control Complex. The Condensate Chemical Treatment System does not contain any liquid-filled piping inside the control complex.
RAI 2.3.4.7-01 Condensate Demineralizer System
Background:
10 CFR 54.21(a)(1) requires applicants to identify and list all SSCs subject to an AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: LRA Section 2.3.4.7 refers to an acid/caustic drain line in paragraph 4 that is located in the auxiliary building. The staff could not locate this drain line on the LRA drawings.
Request: Identify this drain line referred to in the text located in the auxiliary building.
Response
LRA Subsection 2.3.4.7 refers to two drain lines, one acid and one caustic, associated with the Condensate DemineralizerSystem. These two lines have been cut, capped, and disconnected from the Condensate DemineralizerSystem.
One drain line is associatedwith a connection to the neutralizertank and is identified on License Renewal scoping drawings 302-681-LR, Sheet 1 (G-1) and 302-163-LR, Sheet 2 (H-4). This drain line and associated piping components have been brought into the scope of License Renewal per the response to RAI 2.1-2. The response to RAI 2.1-2 was submitted to the NRC
a U. S. Nuclear Regulatory Commission Enclosure 3F1 109-05 Page 46 of 47 in CR-3 letter, 3F0909-04, "Crystal River Unit 3 - Response to Requests for Additional Information for the Review of the Crystal River Unit 3 Nuclear Generating Plant, License Renewal Application (TAC NO. ME0274)," dated September 18, 2009 (ML092650272).
The second drain line is associated with a connection to the spare mix tank and is identified on License Renewal scoping drawings 302-671-LR, Sheet I (A-I) and 302-163-LR, Sheet 2 (H-4).
Since the two cut, capped, and disconnected drain lines could not be verified as non-pressurized in the plant, the lines have been included in scope as non-safety related pressure boundary components in Seismic Class 1 structureshaving the potential for spatial interactions with safety related SSCs.
RAI 2.3.4.8-01 Emergency Feedwater System Back.ground: 10 CFR 54.21(a)(1) requires applicants to identify and list all SSCs subject to an AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: The main condenser is located within the turbine building and the Emergency Feedwater (EFW) pumps are located within the intermediate building (as noted in FSAR Section 10.5.3). CR-3 LRA Drawing 302-082-LR, SH01 shows a cross-connect between main condenser 3B and the suction for EFW pumps Emergency Feedwater Pump (EFP)-I and EFP-2. The cross-connect for EFP-1, the motor driven EFW pump, is through a normally-locked-closed motor operated gate valve shown at location F-7 (EFV-2). Similarly, the cross-connect for EFP-2, the turbine driven EFW pump, is also through a normally-locked-closed motor operated gate valve shown at location E-7 (EFV-1).
The condensate-boundary side of both these valves shows a change from ANSI 31.1 ES to ANSI B31.1 Non-Safety Related, and a change from seismic class III to seismic class I. However, where the change between seismic class occurs for these valves (EFV-1, -2) is not indicated on CR-3 LRA drawing 302-082-LR, SH01, nor does it also indicates where the system piping, components, or structures transition from the turbine building to the intermediate building.
Request: Provide supplemental information on CR-3 LRA drawing 302-082-LR, SH01 to identify where the condensate system supply line to the EFW pumps enters the intermediate building and if there are any changes in the piping classification.
Response
The condensate supply line to the EFW pumps enters the lB between the connection to the Auxiliary Feedwater Pump (which is installed in the TB) and the tee where it splits to go to EFP-1 and EFP-2 (which is located in the IB).
As identified on CR-3 LRA drawing 302-082-LR, SH01, the piping class break from Seismic Class Ill to Seismic Class I does not occur until the upstream connections to EFV-1 and EFV-2, which are downstream of the tee located inside the lB.
RAI 2.3.4.16-01 Main Steam System
U. S. Nuclear Regulatory Commission Enclosure 3F1109-05 Page 47 of 47
Background:
10 CFR 54.21(a)(1) requires applicants to identify and list all SSCs subject to AMR. The staff confirms inclusion of these SSCs subject to an AMR by reviewing the component types within the license renewal boundary.
Issue: On CR-3 LRA drawing 302-011-LR, SH01, there are two unidentified components (RM-G25/G28) shown at locations B-2 and E-2. Both components are attached to an atmospheric line from a normally-closed valve (MSV-25).
Both components are shown as being included in the scope of license renewal.
Request: Provide clarification on what the components are and their intended function for being in scope of license renewal under 10 CFR 54.4(a).
Response
The two components (RM-G25/G28) are main steam line radiationmonitors, and are included in the scope of License Renewal in the Radiation Monitoring (RM) system. A sample line from the Main Steam System is routed past the radiationmonitors. These two radiationmonitors perform a post-accident monitoring function in accordance with Regulatory Guide 1.97.
Radiation monitors RM-G25 (MSV-25) and RM-G28 (MSV-26) monitor a sample from the atmospheric dump valve discharge for gamma dose rate and provide confirmatory indication of atmospheric dump valve position during a Steam GeneratorTube Rupture.
