Requests for Additional Information cc w/encl: Listserv
GRAND GULF NUCLEAR STATION LICENSE RENEWAL APPLICATION REQUESTS FOR ADDITIONAL INFORMATION SET 13 RAI2.2-1 License renewal application (LRA) Section 2.2, Tables 2.2-1-A, 2.2-1-B, 2.2-2, 2.2-3, and 2.2-4 provide the results of applying the license renewal scoping criteria to the systems, structures, and commodities. The license renewal scoping criteria is described in Section 2.1. The following updated final safety analysis report (UFSAR) systems are not located in LRA Tables 2.2-1-A, 2.2-1-B, 2.2-2, 2.2-3, or 2.2-4.
UFSAR Section System 7.5.1.2.18 Post-Accident Sampling Post-accident sampling system 18.1.7 Plant Safety Parameter Display 18.2.2 Safety Parameter Display System Safety related display instrumentation system 11.3 Gaseous Radwaste System Gaseous waste management systems 7.6.2.11 Auxiliary Building Isolation System Auxiliary Building Isolation System Provide additional information to clarify the exclusion of the above systems from Table 2.2-1.
RAI2.3.3-1 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 an 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 in scope for license renewal could not be located.
Drawing Number & Location Continuation Issue 2.3.3.5 Combustible Gas Control LRA-M-1091, location B-2 3"-HBD-924. A continuation was not provided.
2.3.3.7, Standby Service Water LRA-M-1061A, location A-4 4"-HBC-176 line from Unit 2 Pump "B" discharge.

ENCLOSURE
- 2 LRA-M-0036C, location E-8 2"-GBD-11141-"E" continued to drawing LRA-M-1053C location A-7. The continuation of this line on drawing LRA-M-1053C could not be located.
LRA-M-0046, locations E-6, E-8 Nine lines into the Control Building Sanitary Sump and one line into the Acid Neutralization Sump.
Continuations were not provided. These lines are associated with Note 5 on drawing LRA-M-0046.
LRA-M-1080A, location H-8 1 "-JBD-8 continuing from drawing LRA-M-1068A, location B5 (from service air system) could not be located.
LRA-M-1069D, location H-3 Demineralized water in LRA-M-0033B location F-4. The origin of this line on drawing LRA-M-0033B could not be located.
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.
RAI2.3.3-2 LRA Section 2.1.2.1.3, "Mechanical System Drawings," describes the applicant's development of license renewal drawings. This section of the LRA does not describe the use of a solid red line in several license renewal drawings to denote the end of the license renewal scoping boundary. Examples of this notation can be found on Drawings LRA-M-1061A, LRA-M-1094C, and LRA-M-1109F, but not necessarily limited to only these drawings.
Provide additional information to describe the use of the solid red line on license renewal drawings. For all cases where the red line is used, clarify if the piping in question leaves a space that contains components within the scope of license renewal for10 CFR 54.4(a)(1), at the point of the red line. Additionally, for all cases where the red line is used, clarify if the license renewal boundary includes a seismic anchor or equivalent support between the safety related/nonsafety-related interface and the end of the 10 CFR 54.4(a){2) scoping boundary.
RAI 2.3.3.3-1 LRA Table 2.3.3-3 appears to be incorrectly labeled "Suppression Pool Cleanup System Component Subject to Aging Management Review" when it is associated with the Suppression Pool Makeup System, LRA Section 2.3.3.3.
Clarify the title of LRA Table 2.3.3-3 and verify that all components associated with the Suppression Pool Makeup System that are subject to an AMR have been identified.
RAI2.3.3.7-1 LRA Section 2.1.1.2.2(1) states that nonsafety-related structure, system, and components (SSCs) attached to safety-related SSCs are in scope of license renewal for 10 CFR 54.4(a)(2)
- 3 up to the first seismic anchor past the safety-related/nonsafety-related interface. On the following drawings the staff could not locate seismic anchors on the 10 CFR 54.4(a)(2) nonsafety-related lines connected to safety-related lines:
License Renewal Application Drawing Number & Location 10 CFR 54.4(a)(2) Pipe Line(s) or Identifier LRA-M-1061C, location D-6 At valve F119A-A (anchor could not be located on (a)(2) branch line 1"-JCD-5 continuing from drawing LRA-M-0033B, G-1)

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 54.4(a)(2) scoping boundary.
RAI 2.3.3.11-1 License renewal boundary drawing LRA-M-1077A, locations C-6 and H-6, and LRA-M-10770, locations 0-6 and G-6, show the 1"-JOO-19 lines to be in scope for 10 CFR 54.4(a)(1) with continuations from drawing LRA-M-1 067 A. However the continuations of these lines on license renewal boundary drawing LRA-M-1 067 A are shown as not in scope.
Provide additional information to clarify the scoping classification of these pipe sections.
RAI 2.3.3.11-2 LRA Section 2.1.1.2.2(1) states that 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-related/nonsafety-related interface. On the following drawings the staff could not locate seismic anchors on the 10 CFR 54.4(a)(2) nonsafety-related lines connected to safety-related lines:
License Renewal Application Drawing Number & Location 10 CFR 54.4(a)(2) Pipe Line(s) or Identifier LRA-M-1 067 A, location B-3 2" -HCO-533 10 CFR 54.4(a)(2) line connected to line 2" -HCB-51 LRA-M-1068C, location B-3 4"-JBO-26 10 CFR 54.4(a)(2) line connected to line 4" HBC-189 (a single support is shown)
- 5 LRA-M-1068C, location D-5 4" -JBD-26 10 CFR 54.4(a)(2) line connected to line 4"-HBC-189 (a single support is shown)
LRA-M-11 01, location H-5 10 CFR 54.4(a)(2) lines connected to either side of line %"-HBB-231 Provide additional information to locate the seismic anchors or anchored components between the safety-related/nonsafety-related interface and the end ofthe 10 CFR 54.4(a)(2) scoping boundary.
RAI 2.3.3.16-1 License renewal boundary drawings LRA-M-1093B and LRA-M-1093C, location E-3 and E-7, respectively, show fuel injector casings as not within scope for 10 CFR 54.4 (a)(1) and are not listed in Table 2.3.3-16 as a component type subject to an AMR. However, the piping attached to the fuel injector casings is within the scope of license renewal for 10 CFR 54.4.(a)(1).
Justify not including the fuel injector casings within the scope of license renewal under 10 CFR 54.4(a)(1) and why the injector casing component type was excluded from LRA Table 2.3.3-16.
RAI 2.3.3.16-2 License renewal boundary drawing LRA-M-1093A shows fuel pipeline continuations between the diesel generator fuel oil day tank and both Engine A on drawing LRA-M-1093B and Engine B on drawing LRA-M-1093C. The drawings show there is only a single diesel generator fuel oil day tank and single diesel generator fuel oil storage tank for the high-pressure core spray (HPCS) Diesel Generator. The LRA Section 2.3.3.16 description of the HPCS Diesel Generator, Fuel Oil section, states, "[t]he HPCS diesel generator fuel oil system consists of storage tanks, transfer pumps, fuel oil day tanks..." This implies there are multiple storage tanks and day tanks in the system.
The staff requests that the applicant provide additional information to clarify whether there is one or multiple diesel generator fuel oil day tank(s) and diesel generator fuel oil storage tank(s) for the HPCS Diesel Generator.
