2.2 Plant-Level Scoping Results RAI 2.2-1
The applicant's scoping criteria is described in Section 2.1 of the Callaway Plant, Unit 1 (Callaway) License Renewal Application (LRA). LRA Section 2.2, Table 2.2-1, "Scoping Results," provides the results of applying the license renewal scoping criteria to systems, structures, and components (SSCs). The following systems, as described in the Updated Final Safety Analysis Report (UFSAR), could not be located in LRA Table 2.2-1.
The staff requests that the applicant justify its exclusion of the above system from LRA Table 2.2-1.
2.3.3.5 Service Water System RAI 2.3.3.5-1 LRA Section 2.1 describes the applicant's scoping methodology, which specifies how systems or components were determined to be included in scope of license renewal. The staff confirms the inclusion of all components subject to aging management review (AMR) by reviewing the results of the screening of components within the license renewal boundary. For the drawing locations identified in the table below, the continuation of piping within the scope of license renewal could not be located.
License Renewal Boundary Drawing Number & Location Continuation IssueLR-CW-EA-M-22EA01, location E-8 A section of (a)(2) piping (from line 036"-HBD-8" downstream of valve V160) continues to M-22KB02, location B-8, which was not submitted as part of the application. LR-CW-EA-M-22EA01, locations C-6/7 A section of (a)(2) piping (from line 039"-HBD-8" upstream of valve V159) continues to M-22KB02, location B-8, which was not submitted as part of the application. UFSAR Section System 18.1.17 Plant Safety Parameter Display System Safety Parameter Display System The staff requests the applicant to provide sufficient information to locate the license renewal boundary. If the continuation cannot be shown on license renewal boundary drawings, then provide additional information describing the extent of the scoping boundary and verify whether or not there are additional AMR component types between the continuation and the termination of the scoping boundary. If the scoping classification of a section of the piping changes over the continuation, provide additional information to clarify the change in scoping classification.
2.3.3.8 Compressed Air System RAI 2.3.3.8-1 In LRA Section 2.1.2.2 the applicant indicates nonsafety-related SSCs attached to safety-related SSCs are in scope of license renewal for 10 CFR 54.4(a)(2) up to the first seismic anchor past the safety/nonsafety interface. On the following drawings the staff could not locate seismic anchors on the nonsafety related lines:
License Renewal Application Drawing Number & Location 10 CFR 54.4(a)(2) Pipe Line(s) or IdentifierLR-CW-KA-M-22KA01, location B-1 317-JDD-1" downstream of valve V277 (No license renewal boundary drawing M-22KA09 to confirm seismic endpoint) LR-CW-KA-M-22KA04, location F-4 495-JDD- 1/2" downstream of valve V474 LR-CW-KA-M-22KA04, location F-4 Upstream of valve V474 and connected to the 1/2" line with an endpoint shown as RB2 LR-CW-KA-M-22KA04, location F-4 Downstream of valve V483 and connected to the 1/2" line with an endpoint shown as RB17
Provide additional information to locate the seismic anchors or anchored components between the safety/non-safety interface and the end of the 10 CFR 54.4(a)(2) scoping boundary.
2.3.3.20 Fire Protection System The staff has identified that the fire protection systems and components discussed in the following sections have been excluded from the scope of license renewal and an AMR. These systems and components that were not included in the license renewal boundaries appear to have fire protection intended functions required for compliance with 10 CFR 50.48, "Fire protection," as stated in 10 CFR 54.4. Therefore, in order to complete our review, the staff requires responses to the following RAIs: RAI 2.3.3.20-1

The staff requests that the applicant justify why the ejector casing component type was not included in LRA Table 2.3.3-22.
RAI 2.3.3.22-5 License renewal boundary drawings LR-CW-M-22KJ03 and LR-CW-M-22KJ06, location F-5, show oil separator casings that are in scope for 10 CFR 54.4 (a)(1) which are not listed in LRA Table 2.3.3-22 as components subject to an AMR.
The staff requests that the applicant justify why the oil separator casing component type was not included in LRA Table 2.3.3-22.
RAI 2.3.3.22-6
License renewal boundary drawings LR-CW-M-22KJ02 and LR-CW-M-22KJ05, location G-3, show four "XJ" components that are in scope for 10 CFR 54.4(a)(1) that cannot be identified and reviewed. It is uncertain what these components are, what function(s) they perform, and if they are listed in LRA Table 2.3.3-22 as component types subject to an AMR.
The staff requests that the applicant clarify what the components are and their functions, and justify why the component type was not included in LRA Table 2.3.3-22.
2.3.3.27 Floor and Equipment Drainage System
RAI 2.3.3.27-1
License renewal boundary drawing LR-CW-LF-M-22LF01, location H-4, shows A10-XND-4" piping within the scope of license renewal for 10 CFR 54.4(a)(2). However, the continuation from license renewal boundary drawing LR-CW-LF-M-22LF02, location A-4, depicts the piping within the scope of license renewal for 10 CFR 54.4(a)(3).
The staff requests the applicant to provide additional information to clarify the scoping classification of pipe section A10-XND-4".
2.3.4 Steam
and Power Conversion Systems
RAI 2.3.4-1 LRA Section 2.1 describes the applicant's scoping methodology, which specifies how systems or components were determined to be included in scope of license renewal. The staff confirms the inclusion of all components subject to AMR by reviewing the results of the screening of components within the license renewal boundary. For the drawing locations identified in the table below, the continuation of piping in scope for license renewal could not be located.
License Renewal Boundary Drawing Number & Location Continuation IssueSection 2.3.4.2 Main Steam Supply System LR-CW-AB-M-22AB02, location B-6 "F"-HBD-2 & I"-HBD-2, a continuation is not provided Section 2.3.4.4 Steam Generator Blowdown System LR-CW-BM-M-22BM01, locations B-5, C-5, E-5 & G-5 Downstream continuation of valves V039, V028, V017 & V006 continued to drawing M- 22RM01. Drawing M- 22RM01 was not provided for review.
Section 2.3.4.5, Auxiliary Feedwater System LR-CW-AL-M-22FC02, location D-4 Downstream of valve V998 a continuation was not provided.
The staff requests the applicant to provide sufficient information to locate the license renewal boundary. If the continuation cannot be shown on license renewal boundary drawings, then provide additional information describing the extent of the scoping boundary and verify whether or not there are additional AMR component types between the continuation and the termination of the scoping boundary. If the scoping classification of a section of the piping changes over the continuation, provide additional information to clarify the change in scoping classification.
2.3.4.2 Main Steam Supply System
RAI 2.3.4.2-1
License renewal boundary drawing LR-CW-AE-M-22AB02 depicts main steam piping in the auxiliary building highlighted in green, which indicates that the piping is within scope of license renewal for 10 CFR 54.4(a)(1). However, at locations C-2, D-2, F-2, and G-2, four sections of main steam piping exit the auxiliary building and continue into the turbine building. As described by Note 1 on license renewal boundary drawing LR-CW-AE-M-22AB02, the scoping classification change and seismic portion of the main steam piping occurs at the first weld within the turbine building wall. Nonsafety-related components were not identified within scope of license renewal for 10 CFR 54.4(a)(2) inside the turbine building on the license renewal boundary drawing, as required by the applicant's scoping methodology described in LRA Section 2.1.2.2.
The staff requests the applicant to provide justification for excluding the nonsafety-related components in the turbine building, which may be in proximity of the (a)(1) main steam piping, from scope of license renewal for 10 CFR 54.4(a)(2). 2.3.4.3 Main Feedwater System RAI 2.3.4.3-1
License renewal boundary drawing LR-CW-AE-M-22AE01 depicts solenoid valves, which are highlighted in green, at locations A-7, B-7, C-7, D-7, E-7, F-7, G-7, and H-7. These solenoid valves are accompanied on the license renewal boundary drawing with license renewal Note 1, which indicates that these valves are within scope of license renewal under 10 CFR 54.4(a)(1). However, there were not any nonsafety-related components, either directly attached or within spatial proximity of the solenoid valves, identified on license renewal boundary drawing LR-CW-AE-M-22AE01. The exclusion of these nonsafety-related components from scope of license renewal appears to be inconsistent with the scoping methodology described in LRA Section 2.1.2.2. The staff requests the applicant to provide justification for excluding the nonsafety-related components near the solenoid valves from scope of license renewal for 10 CFR 54.4(a)(2) on license renewal boundary drawing LR-CW-AE-M-22AE01. 2.5 Scoping and Screening Results: Electrical and Instrumentation and Control Systems RAI 2.5-1 In the license renewal application, the applicant described the station blackout recovery paths for license renewal. As the licensee did not specifically exclude the associated control circuits and structures for the switchyard circuit breakers, it is assumed that these components are included in the scope of license renewal. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) Section 54.4(a)(3) and License Renewal Sections 2.1.3.1.3 and 2.5.2.1.1 of the Standard Review Plan, the control circuits and structures associated with the circuit breaker should be in the scope of license renewal. Please confirm that these components are within the scope of license renewal.
