Type boundary exists at valves 2VC-1 1-60 and VC-1 1-60 from QAI (Safety Related) to QAIII (Non-Safety Related). The drain piping downstream of the normally closed valves 2VC-1 1-60 and VC-1 1-60 is not required for the Chemical and Volume Control System to accomplish its 10 CFR 54.4(a)(1) function and therefore is not in scope for 10 CFR 54.4(a)(1). A License Renewal system boundary break between the Chemical and Volume Control (VC) system and the Waste Disposal (WD) System should be shown on the downstream side of these valves.
Part 2 The analysis of record shows the seismic endpoints for the Volume Control Tank (VCT) drains are at the point the lines become embedded in the Ground Floor Elevation 695'-
0" slab. The embedded pipe, beginning at the Ground Floor Elevation 695'-0" slab (shown on Drawing LR-39248 locations E-8 and E-5) and continuing until it exits the concrete just upstream of valve WL-51 -1 (shown on Drawing LR-39248 location G-7), is within the scope of License Renewal per 10 CFR 54.4(a)(2) as a seismic anchor. A seismic anchor should be shown on drawing LR-39248, location G-7, upstream of valve WL-51 -1, where the drawing currently depicts a wall.

Request:
Provide justification for not including these components in scope for 10 CFR 54.4(a)(1).
NSPM Response to RAI 2.3.3.2-05 The boric acid storage tanks and associated components are designated as Safety Related based on plant preference. NEI 95-10 acknowledges that some components may be designated as Safety Related, but not meet the definition of the Rule. Section

====3.1.1 states====
It is conceivable that, because of plant unique considerations and preferences, applicants may have previously elected to designate some systems, structures and components as safety related that do not perform any of the requirements of 54.4(a)(1). Therefore, a system, structure or component may not meet the requirements of 54.4(a)(1) although it is designated as safety related for plant specific reasons.
License Amendments 156/147 dated April 16, 2001, removed the boric acid storage tanks (BASTs) from the Technical Specifications for the Safety Injection System because the high concentration boric acid in the BASTs is unnecessary for accident mitigation. Therefore the BASTs are not required to accomplish the functions described in 54.4(a)(1) and are not within the scope of License Renewal for 10 CFR 54.4(a) (1).
The tanks are included within the scope of License Renewal for 10 CFFR 54.4(a) (2).

Enclosure 1 NSPM Responses to NRC Requests for Additional Information Dated November 19, 2008 NSPM Response to RAI 2.3.3.4-01 Part 1 The original function of the air supplies to containment was to provide air, which when added to containment, would compress the hydrogen and thus dilute its concentration.
The penetrations were equipped with normally closed isolation valves, throttle valves and field connections for use of oil-free compressors (i.e., an Emergency Air Supply on loss of the plant instrument air supply). Field connections were also provided for an Emergency Instrument Air Supply for control of the valves within the Hydrogen Control System. License Amendments 164/154 dated June 8, 2004, eliminated the requirements that necessitated the need for a hydrogen control function, and the associated description of the system was removed from the USAR. As described in LRA Section 2.3.3.4, Function HC-02, the system is currently used to control positive pressure within the containment vessel. This is not an Intended Function.
Part 2 The four (4) Emergency Instrument Air lines do not continue on Instrument Air System Drawing LR-39244; these lines terminate at local field connections similar to the Emergency Air Supply field connections. They may be used to connect to an external air supply for control of the valves within the Hydrogen Control System on loss of the plant instrument air supply. As described above, this is not an Intended Function.

Review of LRA Section 2.3.3.16 indicated that the fuel-transfer tube and blind flange are included as part of the SF System. In the System Function Listing subsection, the fuel-transfer tube is listed under Code SF-05, which applies to SCs relied upon to perform a Primary Containment Boundary Function. The fuel-transfer tube and blank flange with double O-Ring seal constitute the containment boundary. Therefore, the fuel-transfer tube meets the criterion for 10 CFR 54.4(a)(1). The fuel-transfer tube also meets the Code SF-SB requirement because it performs a containment isolation function that demonstrates compliance with 10 CFR 50.63, Station Blackout. Therefore, the fuel transfer tube is also in scope for license renewal per 10 CFR 54.4(a) (3).

Although the fuel-transfer tube is in scope for license renewal per 10 CFR 54.4(a)(1) and (a)(3), there was little information describing the fuel-transfer tube or the license renewal boundary in the LRA. A drawing was not provided. The fuel-transfer tube and blind flange are also not included in LRA Table 2.3.3-16.
Request:
: 1. Provide reference to a LRA drawing showing the fuel-transfer tube and license renewal boundaries.
: 2. Justify why the fuel-transfer tube and blank flange are not component types requiring an AMR in LRA Table 2.3.3-16, "Spent Fuel Pool Cooling System."

Issue:
Similar piping is in scope for different criteria. Drawing LR-39253-3, location F-7, shows several lines from air compressor (#125) as in scope for license renewal for 10 CFR 54.4(a)(3). Drawing LR-39253-3, location C-7, also shows that similar lines from the air compressor (#124) are in scope for license renewal for 10 CFR 54.4 (a)(2). LRA Section 2.3.3-17, "Station and Instrument Air System," does not indicate that any portion of the station and inst'rument air system is in scope for 10 CFR 54.4 (a)(2).
Request:
: 1. Provide additional information explaining why there is a difference of scope classification between the lines out of air compressors #124 and #125 when both the compressors have essentially the same piping size, function, and destination that enables both units to meet the requirements of 10 CFR 54.4 (a).
: 2. If the sections of pipe currently in scope for 10 CFR 54.4 (a)(2) on license renewal drawing LR-39253-3 remain in scope for 10 CFR 54.4 (a)(2), explain why LRA Section 2.3.3.17 does not address components in scope for 10 CFR 54.4 (a)(2).

 #125 Station Air Compressor is required to be available as a backup for Fire Protection Safe Shutdown in compliance with 10 CFR 50, Appendix R. Therefore, the Cooling 42

Enclosure 1 NSPM Responses to NRC Requests for Additional Information Dated November 19, 2008 Water supply and return lines to #125 Station Air compressor and Aftercooler are within the scope of License Renewal for 10 CFR 54.4(a) (3): The #124 Station Air Compressor is not required for Fire Projection Safe Shutdown. Therefore, the Cooling Water supply and return lines to #124 Station Air Compressor and Aftercooler are within the scope of License Renewal for 10 CFR 54.4(a)(2). Continued functionality of the Cooling Water System following a pipe break has been demonstrated using hydraulic analysis techniques (see USAR Section 10.4.1.2.4), and therefore, only the dedicated flow path to #125 Station Air Compressor is in scope for 54.4(a)(3).
Part 2 On drawing LR-39253-3, location F-7 and C-7, the lines that are shown in scope due to different scoping criteria are the station air compressor and aftercooler Cooling Water (CL) System supply and return lines. These lines are evaluated in the LRA Section 2.3.3.6, Cooing Water System. The boundary breaks are depicted in the typical detail sketches at locations H-2 and F-i. These Cooling Water lines are addressed in LRA Section 2.3.3.6, which includes components within the scope of License Renewal for both 10 CFR 54.4(a)(2) and 10 CFR 54.4(a)(3) (see function CL-NSAS and CL-FP).
The #124 and #125 Station Air Compressor components that perform a station air pressure boundary function are in scope for 54.4(a)(3) to maintain the compressed air Fire Protection Safe Shutdown pressure boundary. LRA Section 2.3.3.17 addresses Station and Instrument Air components in scope for 10 CFR 54.4(a)(3) (see function SA-FP).

NSPM Response to RAI 2.3.3.20-06 A rupture of the waste gas decay tanks does not result in offsite exposures comparable to (i.e. greater than or equal to 10% of) those referred to in 10 CFR 100.11, and therefore, the tanks are not within the scope of License Renewal per 10 CFR 54.4(a)(1).
For a discussion related to the definition of the term "comparable" and the basis for the 10% criterion, see the response to RAI 2.1-1 contained in the NSPM letter to the NRC dated December 5, 2008.
The waste gas decay tanks are designated as safety related based on a PINGP-unique criterion of 1% of 10 CFR 100 limits contained in the PINGP USAR and plant procedures. NEI 95-10 acknowledges that some components may be designated as safety related, but not meet the definition of the Rule. Section 3.1.1 of NEI 95-10 states:
It is conceivable that, because of plant unique considerations and preferences, applicants may have previously elected to designate some systems, structures and components as safety related that do not perform any of the requirements of 54.4(a)(1). Therefore, a system, structure or component may not meet the requirements of 54.4(a)(1) although it is designated as safety related for plant specific reasons.
As shown in USAR Section 14.5.3.2, a rupture of a waste gas decay tank does not result in offsite exposures comparable to (i.e. greater than or equal to 10% of) those referred to in 10 CFR 100, and therefore, the tanks are not within the scope of License Renewal for 10 CFR 54.4(a)(1).
