GRAND GULF NUCLEAR STATION LICENSE RENEWAL APPLICATION REQUESTS FOR ADDITIONAL INFORMATION SET 15 RAI2.3.4-1 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 aging management (AMR) by reviewing the results of the screening of components within the license renewal boundary. For the license renewal boundary drawing locations identified in the table below, the continuation of piping in scope for license renewal could not be located.

! Drawing Number & Location Continuation Issue

• 2.3.4.2, Miscellaneous Steam and Power Conversion Systems in Scope for 10 CFR 54.4(a)(2)

LRA-M-1 051 B, locations C-4 & C-SI Downstream of reactor feed pump turbi ne rupture disks.

LRA-M-11168, location C-6 1"-HCD-407 piping "to CHRW." A continuation was not provided.

LRA-M-1117F, location D-1 1 Y2" piping "to lube oil tank." A continuation was not provided.

Provide sufficient information to locate the license renewal boundaries. If the continuation cannot be shown on license renewal boundary drawings, then provide additional information describing the extent of the scoping boundary and if 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.

RAI 2.3.4.1-1 LRA Section 2.1.2.1 states that nonsafety-related SSCs attached to safety-related SSCs are within the scope of license renewal for 10 CFR 54.4(a)(2) up to the first seismic anchor past the safety-related/nonsafety interface. On the following license renewal boundary drawings the staff could not locate seismic anchors on the non-safety related lines:

! Number & Location LRA-M-106S, location B-4 12"-HBC-203 upstream of valve 01 P11 F061 LRA-M-106S, location C-4 12"-HBC-204 upstream of valve 01 P11 F067 Provide additional information to locate the seismic anchors or anchored components between the safety-related/nonsafety-related interface and the end of the 10 CFR S4.4(a)(2) scoping boundary.

RAI 2.3.4.1-2 License renewal boundary drawing LRA-M-106S, locations B-6 and C-6, shows expansion joints XJ-GS21 to be within the scope of license renewal. However, similar expansion joints (XJ-GS22) at location E-S are not shown as within the scope of license renewal, and noted as "not long-lived."

Provide additional information to clarify the difference in scoping classification.

RAI 2.3.4.2-1 In the following instances, license renewal boundary drawings show piping "to & from turbine bldg. cooling water system" and vent piping as not within scope of license renewal. However, these piping sections are shown on license renewal boundary drawing LRA-M-1062B as within the scope of license renewal for 10 CFR S4.4(a)(2).

License Renewal Drawing Location LRA-M-1066B Sht. 001 and 002 C-7 LRA-M-1066C B-8 LRA-M-1120B B-3, B-4, B-S, B-6, B-7, B-8, E-6 LRA-M-1117 A B-2, B-3 LRA-M-1121 B-3, C-3, C-4, C-S LRA-M-1092A C-8 Provide additional information to clarify the scoping classification of these pipe sections.

RAI 2.3.4.2-2 Condensate and feedwater system license renewal boundary drawing LRA-M-10S3E, locations F-4, F-6, and F-8, shows 1/2"-GBD-188, 1/2"-GBD-187, and 1/2"-GBD-186, "oxygen flow control rack," piping to the condensate system as not within the scope of license renewal. However, the piping is connected to in-scope piping without a separation (Le., valve).

Provide additional information to justify the scoping classification of these pipe sections.

- 3 RAt 2.3.4.2-3 Circulating water system license renewal boundary drawing LRA-M-10598, locations 8-3 and 8-4, shows injection nozzles of the condenser tube cleaning system "A" & "8" as within the scope of license renewal. LRA Table 2.3.4-2-18 does not list these injection nozzles.

Provide additional information to justify the exclusion of injection nozzles from LRA Table 2.3.4-2-18.

RAI 2.3.4.2-4 Main and reheat steam system license renewal boundary drawing LRA-M-1051A, locations C-3 and C-4, shows two 48" lines to the low pressure turbines A and C from the moisture separator reheaters as not within the scope of license renewal. However, the 48" line to the low pressure turbine 8 from the moisture separator reheater is shown as within the scope of license renewal for 10 CFR 54.4(a)(2).

Additionally, moisture separator reheater vents and drains system license renewal boundary drawings LRA-M-1056A & 8, locations G-4 & G-5, show 1" vent piping to the moisture separator reheater hot reheat line as not within scope of license renewal. However, these lines are connected to the moisture separator reheaters, which are in scope for 10 CFR 54.4(a)(2).

Provide additional information to justify the scoping classification of these pipe sections.

RAI 2.3.4.2-5 Main and reheat steam system license renewal boundary drawing LRA-M-10510, location F-7, shows 6"-H80-1145 piping from the 2nd stage reheater "8" excess steam bypass to the moisture separator/reheater as not within the scope of license renewal. However, on license renewal boundary drawing LRA-M-10568, location G-8, this pipe is shown as within the scope of license renewal for 10 CFR 54.4(a)(2).

Provide additional information to clarify the scoping classification of this pipe section.

RAI 2.3.4.2-6 Lube oil system license renewal boundary drawing LRA-M-10660 was included in the drawing package but is not included in the table of license renewal boundary drawings in LRA Section 2.3.4.2.

Clarify why license renewal boundary drawing LRA-M-10660 is not included in the list of drawings associated with the lube oil system.

- 4 RAJ 2.3.4.2-7 Seal oil system license renewal boundary drawings LRA-M-1116A & B show details for miscellaneous vents and drains for turbine generator equipment. However, there are inconsistencies between the information presented in drawing LRA-M-1116A, Table 1, and the highlighted detail drawings for valves and piping in scope for 10 CFR 54.4(a)(2). For example, valve NIN44F119 is highlighted in scope on LRA-M-1116A, Table 1 but is not highlighted in the connection M52 drawing or the associated detail drawing. Another example is the %"-HCD-410 that is shown as within the scope of license renewal in the connection M38 drawing and drawing LRA-M-1116A, detail 5, but shown as not within scope of license renewal in LRA-M-1116A, Table 1.

Provide additional information to clarify the discrepancies between the scoping boundaries shown in LRA-M-1116A, Table 1, and the connection and detail drawings.

RAI 2.3.4.2-8 Seal oil system license renewal boundary drawing LRA-M-1116B, location G-8, shows the detail for connection M51 as within the scope of license renewal for 10 CFR 54.4(a)(2). However, drawing LRA-M-1116A, Table 1, does not have any information on connection M51.

Provide additional information to clarify the scoping classification for connection M51.

RAI 2.3.4.2-9 Generator primary water system license renewal boundary drawing LRA-M-1044A, location G-6, shows "Cooler B003" as not within the scope of license renewal. However lines 1"-,JBD-1341 and 1"-JBD-1342 run through the cooler and are within the scope of license renewal for 10 CFR 54.4(a)(2).

Provide additional information to clarify why cooler B0003 is not shown as within the scope of license renewal.

RAI 2.3.4.2-10 Generator primary water system license renewal boundary drawing LRA-M-1044A, locations F-1 and E-6, show traps D035 & D037 as within the scope of license renewal. LRA Table 2.3.4-2-14 does not list traps as a component type subject to AMR.

Provide additional information to justify the exclusion of a trap component type from Table 2.3.4-2-14.

RAI 2.3.4.2-11 Main turbine and auxiliaries system license renewal boundary drawing LRA-M-1117A, locations D-3 and D-4, show valves PV F505A and PV 505B with associated piping as not within the

-5 scope of license renewal. However, these valves are shown on drawing LRA-M-1 057A, location H-4, as within the scope of license renewal for 10 CFR 54.4(a)(2).

Provide additional information to clarify the scoping classification of these pipe sections.

RAI 2.3.4.2-12 Main turbine and auxiliaries system license renewal boundary drawing LRA-M-1117 A, location A-2, shows the "control fluid purifier skid" as not within the scope of license renewal. However, the lines connecting to this skid are within the scope of license renewal for 10 CFR 54.4(a)(2).

Provide additional information to justify the exclusion of the "control fluid purifier skid" from the scope of license renewal.
