However, the flame arrestor housing that is not listed in Table 2.3.3-8 as a component type subject to an AMR.
The staff requests the applicant to justify the exclusion of the flame arrestor housing component type from LRA Table 2.3.3-8.
RAI 2.3.3.8-05 License renewal boundary drawings LR-M-20 Sheets 3 and 9, location F-5, depict diesel generators 1AG501 and 2AG501 as not being within the scope of license renewal. The continuation lines to diesel generators, at locations B-5 and B-6 on both sheets, also depict the three other diesel generators at each plant (Unit 1 1BG501, 1CG501, 1DG501, and Unit 2 2BG501, 2CG501, and 2DG501) as not being within the scope of license renewal.
The staff requests the applicant to justify why all the emergency diesel generators indicated on license renewal boundary drawings LR-M-20 Sheets 3 and 9 are indicated as not being within the scope of license renewal.
2.3.3.12 Nonsafety-Related Service Water System RAI 2.3.3.12-01 License renewal boundary drawings LR-M-10 Sheets 5 and 10, locations H-2 and H-4, depict the 6 JBD-107/207 and 6 JBD-132/232 lines to be within the scope of license renewal for 10 CFR 54.4(a)(2) with continuations to and from license renewal boundary drawings LR-M-10 Sheets 3 and 8. However, the continuations of these lines on license renewal boundary drawings, LR-M-10 Sheets 3 and 8, are depicted as not being within the scope of license renewal.
The staff requests the applicant to clarify the correct scoping classification of these pipe lines.
2.3.3.13 Plant Drainage System RAI 2.3.3.13-01 On license renewal boundary drawing, LR-M-64 Sheet 1, location G-8, the continuation of the pipe line depicted within the scope of license renewal could not be found in any other license renewal boundary drawings.
The staff requests the applicant to locate the continuation line for the above location. If the continuation line 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.
2.3.3.14 Primary Containment Instrument Gas System RAI 2.3.3.14-01 LRA Section 2.1 describes the applicants 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.
On license renewal boundary drawing LR-M-59 Sheet 1, location C-6, the applicant depicts Note 5, which states This piping is included in scope out to the seismic anchor credited for structural support of the safety-related piping located as shown. The non-safety-related piping beyond this anchor location is not in scope. However, the 1 JCD-109 pipe continues in red, designating the piping as being within the scope of license renewal for 10 CFR 54.4(a)(2), from Note 5 to the end of the pipe and including the drawing continuation marker to drawing LR-M-59 Sheet 2, at location F-1. The continuation marker on Sheet 2 also shows the pipe still in scope for 10 CFR 54.4(a)(2) and has another Note 5, the same as Sheet 1, where the transition is actually made from red to black to indicate the 1 JCD-109 pipe continuation changed to not being in scope for license renewal. For Unit 2, LRA drawing LR-M-59 Sheet 3, location C-6, the 1JCD-209 pipe has the same Note 5 and there is an immediate transition from red to black, so the remainder of the pipe up to and including the continuation marker is no longer in scope as the Note 5 indicates. There also is no duplicate Note 5 on Sheet 4.
The staff requests the applicant to clarify why the 1 JCD-109 pipe scope does not agree with Note 5 on LRA drawing LR-M-59 Sheet 1. Also clarify why there are differences in scoping between the 1 JCD-109 pipeline on Sheets 1 and 2 and the 1 JCD-209 pipeline on Sheets 3 and 4.
RAI 2.3.3.14-02 License renewal boundary drawing LR-M-59 Sheet 3, location H-6, depicts a line not highlighted within the scope of license renewal. However, the line is connected to a continuation marker from drawing LR-M-42 Sheet 3, location A-3, which depicts the continuation marker to be highlighted green and in scope for 10 CFR 54.4(a)(1).
The staff requests the applicant to clarify the scoping classification of the pipe line.
2.3.3.17 Process Radiation Monitoring System RAI 2.3.3.17-01 License renewal boundary drawings LR-M-26 Sheets 1 and 7, location C-2, and LR-M-26 Sheet 4, location B-7, depict sample chambers in Detail K that are within the scope of license renewal for 10 CFR 54.4(a)(2), but are not listed in Table 2.3.3-17 as a component type subject to an AMR.
The staff requests the applicant to justify the exclusion of the sample chamber component type from LRA Table 2.3.3-17.
RAI 2.3.3.17-02 License renewal boundary drawing LR-M-26 Sheet 5, location E-3, depicts filter and detector housings in Detail G that are within the scope of license renewal for 10 CFR 54.4(a)(1), but are not listed in Table 2.3.3-17 as a component type subject to an AMR.

2.3.4.3 Condenser and Air Removal System RAI 2.3.4.3-01 License renewal boundary drawings LR-M-07 Sheets 1 and 3, location H-2, depict air inlets with screens that are within the scope of license renewal for 10 CFR 54.4(a)(2), but are not listed in Table 2.3.4-3 as a component type subject to an AMR.
The staff requests the applicant to justify the exclusion of the air inlet with screen component type from LRA Table 2.3.4-3.
2.3.4.6 Main Steam System RAI 2.3.4.6-01 On license renewal boundary drawing, LR-M-05 Sheet 1, locations G-3, G-4 and G-6, the continuation of the 1 1/2 Bearing Drain to Oily Waste pipe from the condenser could not be found on the following license renewal boundary drawings because the drawings were not included in the license renewal boundary drawings package:
M-19 Sheet 3 M-19 Sheet 6 The staff requests the applicant to provide the license renewal boundary for the 1 1/2 Bearing Drain to Oily Waste pipe for the license renewal boundary drawings described above. If the continuation line cannot be shown on these 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.
2.3.4.7 Main Turbine RAI 2.3.4.7-01 Drawing LR-M-07 Sheet 2, location F-6, shows in scope pipeline 1 HBD-359, however the continuation on this same drawing at location B-4 shows this pipeline as not in scope.
The staff requests the applicant to provide additional information to clarify the scoping boundary of this pipe section.
RAI 2.3.4.7-02 License renewal boundary drawings LR-M-07 Sheets 2 and 4, location E-7, depict drain pipelines 1 HBD-359, and 1 HBD-459 within the scope of license renewal for 10 CFR 54.4(a)(2). However, license renewal boundary drawings LR-M-06 sheets 2 and 5, location D-8, depict the continuation lines as not being within the scope of license renewal.
The staff requests the applicant to clarify the scoping boundaries for the pipe lines.
