License Renewal Application (LRA)
Draft Request for Additional Information Set 11 Balance of Plant, Fire Protection, and Nickel Alloy Balance of Plant D-RAI 2.3A.2.2-1 Containment Spray The aging management review (AMR) boundary for a system is typically highlighted on license renewal drawings. However, the license renewal drawings provided to the staff did not contain a depiction of (a)(2) boundaries or components. Section 2.3.2.2 of the license renewal application (LRA) states: The containment spray system has no intended function for 10 CFR 54.4(a)(2).
On Unit 2 license renewal drawing LRA-9321-2735 (containment spray system), the piping line
- 187, including valve 872D 3/4-T58 was not highlighted, but it appears to be directly connected to safety-related spray piping. This piping is located downstream of the safety class boundary on the suction piping, 12-SI-151R- #181, from the refueling water storage tank (RWST) to the containment spray pump at branch connection, 2-SI-151R- #588, ending at valve 873B 2-T58.
Similarly, there is a non-highlighted mini-flow recirculation line from the pump. Piping downstream of the safety class boundary may not be required to perform the safety-related function, but may need to be included in scope under 10 CFR 54.4(a)(2).
Indicate whether portions of the above system(s) were evaluated for inclusion within the scope of license renewal in accordance with 10 CFR 54.4(a)(2). Identify all other instances, whereby a safety-related system, which has nonsafety-related components, was scoped in per 10 CFR 54.4(a)(1), but those nonsafety-related components were not identified as in scope for 10 CFR 54.4(a)(2).
D-RAI 2.3A.4.2-2 Auxiliary Feedwater Section 2.3.4.3 of the license renewal application (LRA) states: The AFW system has no intended function for 10 CFR 54.4(a)(2).
The following components on safety-related system(s) are not highlighted, but may need to be considered for 10 CFR 54.4(a)(2):
- auxiliary feedwater pump bearing cooling line on license renewal drawing LRA-9321-2018-0 (Unit 2),
- chemical feed line to auxiliary feedwater between 3/4 -BFD-65-19 on license renewal drawing LRA-9321-2038-0 to 2-inch piping connected to BFD-1131 on license renewal drawing LRA-9321-2019-0 (typical) (Unit 2),
- piping and associated valve SS-189 off of the auxiliary feedwater supply header on license renewal drawing LRA-9321-20183-001 (at location D-7) (Unit 3).
Indicate whether portions of the above system(s) were evaluated for inclusion within the scope of license renewal in accordance with 10 CFR 54.4(a)(2). It is noted that in D-RAI 2.3A.2.2-1, above, the extent of condition has been requested.
D-RAI 2.2B-2 Nonsafety-related SSCs directly connected to safety-related SSCs must be structurally sound in order to maintain the pressure boundary integrity of safety class piping. The nonsafety-related piping and supports up to and including the first seismic anchor beyond the safety/nonsafety interface may need to be in-scope in order to assure that the safety-related portion of the piping will be able to perform its intended function.
In the (a)(2) scoping document and LRA Table 2.2-2-IP3, the hydrogen gas system was labeled not in-scope. This system, along with the nitrogen system, has the function to provide the volume control tank (VCT) with gas for oxygen scavenging. Since the piping is directly connected to the VCT, the applicant should consider including the system in-scope for (a)(2) for potential physical interaction between the nonsafety and safety-related equipment.
Evaluate placing the hydrogen system and/or nitrogen system in-scope for (a)(2) and evaluate any other interfaces of gas system interaction with safety-related equipment.
D-RAI 2.3.0-2 Several LRA drawings identify various components as Not A Long Lived Component, i.e., the component is not subject to an aging management review (AMR).
- Drawing LRA-9321-2720 and LRA-9321-27203 for Unit 2 and Unit 3, respectively, show several components for the component cooling water system to the reactor coolant pumps 21, 22, 23, and 24.
- Drawing LRA-9321-2028 and LRA-9321-20283 show the pump for the Unit 2 and Unit 3 emergency diesel generator (EDG) water jacket cooling system.
In NUREG-1800, Rev. 1, Section 2.1.3.2.2 describes long-lived structures and components as those that are not subject to periodic replacement based on a qualified life or specified time period. Furthermore, it states that replacement programs may be based on vendor recommendations, plant experience, or any means that establishes a specific replacement frequency under a controlled program.
Other license renewal applications, typically have not designated pumps, motors, and heat exchangers as not long lived, i.e., these components, or portions thereof, are subject to an AMR.
a) Identify the component types serviced by the component cooling water system indicated in the above mentioned drawings that are shown as not long lived.
b) Provide a basis for designating these components as not long lived to include details on how the qualified life of the components was established and describe the program under which aging management activities for the components are performed, and any available plant-specific operating experience confirming the effectiveness of management activities.
Nonsafety-Related Components LRA Sections 2.1.1.2 and 2.1.2.1.2 describe the specific details for applying the methodology for identifying nonsafety-related portions of systems with a potential for adversely affecting safety-related functions in accordance with 10 CFR 54.4(a)(2). LRA Section 2.1.2.1.3 states that license renewal drawings were prepared to indicate portions of systems that support system intended functions with the exception of those systems in-scope for 10 CFR 54.4(a)(2) for physical interactions.
Because nonsafety-related system portions meeting 10 CFR 54.4(a)(2) for physical interactions are not indicated on the license renewal drawings, further information is required by the staff to complete its review to confirm that the licensee has adequately identified components in-scope for (a)(2).
For each of the following license renewal drawings identified below, describe the specific portions of the system piping that are within the scope of license renewal for meeting 10 CFR 54.4(a)(2) for physical interactions, or justify their exclusion.

Fire Protection D-RAI 3.0.3.2.7-1 LRA Table 2.4-4 lists fire stops and fire wrap as bulk commodities that perform an intended function of fire barrier. LRA Table 3.5.2-4, Bulk Commodities, identifies the material, environment and aging effect requiring aging management for these two commodities. The Fire Protection Program is identified as the aging management program along with Note J which indicates that neither the component nor the material and environment combination is evaluated in NUREG-1801. However, in LRA Section B.1.13, Fire Protection, there is no indication that fire stops and fire wrap are included as commodities whose aging effects will be managed by the AMP. Describe how the aging effects of cracking/delamination, separation (for fire stops),
and loss of material (for fire wrap) will be managed under the Fire Protection AMP.
Nickel Alloy D-RAI 3.0.3.3.5-1 The Nickel Alloy Inspection Program for the monitoring and trending program element states that records of the inspection program, examination and test procedures, examination/test data, and corrective actions taken or recommended are maintained in accordance with the requirements of ASME Section XI, Subsection IWA.
The Standard Review Plan for License Renewal (SRP-LR) Section A.1.2.3.5, and SRP-LR Table A.1-1 state that:
Monitoring and trending activities should be described, and they should provide predictability of the extent of degradation and thus effect timely corrective or mitigative actions. Plant-specific and/or industry-wide operating experience may be considered in evaluating the appropriateness of the technique and frequency. This program element describes how the data collected are evaluated and may also include trending for a forward look. This includes an evaluation of the results against the acceptance criteria and a prediction regarding the rate of degradation in order to confirm that timing of the next scheduled inspection will occur before a loss of SC intended function. Although aging indicators may be quantitative or qualitative, aging indicators should be quantified, to the extent possible, to allow trending. The parameter or indicator trended should be described. The methodology for analyzing the inspection or test results against the acceptance criteria should be described. Trending is a comparison of the current monitoring results with previous monitoring results in order to make predictions for the future.
Please describe how the monitoring and trending program elements will be addressed in the Nickel Alloy Inspection Program.
D-RAI 3.0.3.3.5-2 LRA Table 3.1.1, Item 3.1.1-31 is applicable to NUREG-1801, Rev. 1, Items IV.A2-12, IV.A2-19, and IV.C2-13, which specify that an acceptable aging management program is to comply with applicable NRC Orders and provide a commitment in the FSAR supplement to implement applicable (1) Bulletins and Generic Letters and (2) staff-accepted industry guidelines.
The statement in the Nickel Alloy Inspection Program states that Indian Point will continue to implement commitments associated with (1) NRC Orders, Bulletins and Generic Letters associated with nickel alloys and (2) staff accepted industry guidelines.
The intent of this statement is unclear. Please clarify that the applicant commits to comply with applicable Bulletins, Generic Letters and staff-accepted industry guidelines.
