Response to Request for Additional Information Docket No.52-048 eRAI No.: 9681 Date of RAI Issue: 05/30/2019 NRC Question No.: 14.03-3 Please see the attachment to this Request for Additional Information.

Title 10, Section 52.47(b)(1) of the Code of Federal Regulations (CFR) requires that a design certification application contain the proposed inspections, tests, analyses, and acceptance criteria (ITAAC) that are necessary and sufficient to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, a facility that incorporates the design certification has been constructed and will operate in accordance with the design certification, the provisions of the Atomic Energy Act of 1954, as amended (AEA),

and the NRC's rules and regulations. For the ITAAC to be "sufficient," (1) the inspections, tests, and analyses (ITA) must clearly identify those activities necessary to demonstrate that the acceptance criteria (AC) are met; (2) the AC must state clear design or performance objectives demonstrating that the Tier 1 design commitments (DCs) are satisfied; (3) the ITA and AC must be consistent with each other and the Tier 1 DC; (4) the ITAAC must be capable of being performed and satisfied prior to fuel load; and (5) the ITAAC, as a whole, must provide reasonable assurance that, if the ITAAC are satisfied, the facility has been constructed and will be operated in accordance with the design certification, the AEA, and the NRC's rules and regulations.

The staff has reviewed all DCD Rev 2, Tier 1 ITAAC tables and Chapter 1 of Tier 1 against these objectives, and in light of NRC guidance, Commission policy, and lessons learned from plants that are currently under construction that are in the process of implementing ITAAC.

Based on this review, the staff has compiled the attached list of proposed ITAAC wording changes. The applicant is requested to make these changes in the Tier 1 ITAAC tables and in Chapter 1 of Tier 1, or otherwise show that the ITAAC comply with 10 CFR 52.47(b)(1).

Additionally, the applicant is requested to address the following items, or otherwise show that NuScale Nonproprietary

the ITAAC comply with 10 CFR 52.47(b)(1):

1. ITAAC 29 in Table 2.5-7 verifies that the MCR isolation switches are located in the remote shutdown station but it does not verify the functionality of the switches. Please explain how ITAAC 29 verifies that the MCR isolation switches actually isolate the manual MCR switches from the MPS in case of fire. If ITAAC 29 does not verify the functionality of the MCR isolation switches, please explain what changes to the existing ITAAC in Tier 1 would be necessary to verify the functionality of the MCR isolation switches through ITAAC. If the applicant believes that ITAAC are not necessary to verify the functionality of the MCR isolation switches, please explain this and please explain why an ITAAC is, nonetheless, necessary to verify the location of the MCR isolation switches.
2. The design commitments listed in the design descriptions of DCA Part 2, Tier 1 are not consistent with the design commitments in the corresponding ITAAC tables. Although not identified in the attachment, the design commitments in the design descriptions of DCA Part 2, Tier 1 should be revised to be consistent with the design commitment in the ITAAC tables.

Additional explanations for the basis of the staff's proposed revisions in the attachment are provided below:

1. Tier 1, Section 1.1: Propose adding a definition of "approved design" to clarify what this term refers to. Without a definition, it is not clear who the approver is or when the design is considered approved (at certification or when the ITAAC is closed?). To provide clarity and flexibility, the staff proposes to define the "approved design" in terms of the updated final safety analysis report.
2. Tier 1, Section 1.2.4: Propose adding explanatory material consistent with past design certifications as applied to the NuScale design.
3. ITAAC 12 in Table 2.1-4: To resolve the use of the ambiguous word, "approximately" in the AC.
4. ITAAC 22 in Table 2.1-4: To clarify the applicability of the ITAAC to the assemblies and to add consideration of overload currents.
5. ITAAC 1 and 2 in Table 2.3-1: To make the scope of the ITA and AC consistent with the DC.
6. ITAAC 3, 4, and 6 in Table 2.5-7: To clarify the applicability of physical separation, electrical isolation, and communications independence in the DC and ITAAC.
7. ITAAC 15 in Table 2.5-7: To clarify the DC and make the DC consistent with the AC.
8. ITAAC 21 in Table 2.5-7: To clarify the DC and resolve an inconsistency between the DC and AC.

NuScale Nonproprietary

9. ITAAC 2, 3, and 4 in Table 2.7-2: The DCs for ITAAC 2 to 4 relate to a single Chemical Volume and Control System (CVCS) high radiation signal, but the AC for each ITAAC cover all 3 CVCS radiation signals. The proposed changes consolidate ITAAC 2 to 4 so that the scope of the DC matches the scope of the AC.
10. ITAAC 1 in Table 3.4-1: To resolve an inconsistency between the DC and AC.
11. ITAAC 4 in Table 3.4-1: The DC is actually an ITA. The staff's proposed revisions correct this.
12. ITAAC 2 in Table 3.5-1: To remove an unnecessary conditional statement in the DC and to clarify what the "approved" analysis is.
13. ITAAC 3 in Table 3.7-1: To clarify in the AC the alternative shutdown capability referred to in the DC.
14. ITAAC 4, 5, and 6 in Table 3.9-2: See explanation for ITAAC 2, 3, and 4 in Table 2.7-2.
15. ITAAC 8 and 9 in Table 3.9-2: See explanation for ITAAC 2, 3, and 4 in Table 2.7-2.
16. ITAAC 1, 2, and 3 in Table 3.10-1: To resolve inconsistencies between the DC and AC.
17. ITAAC 7 in Table 3.10-1: The DC is actually an ITA. The staff's proposed revisions correct this and make it consistent with the AC.
18. ITAAC 8 in Table 3.10-1: This ITAAC could be deleted if the proposed revisions to ITAAC 7 in Table 3.10-1 are incorporated as shown in the attachment since the scope of the revised ITAAC 7 would encompass the scope of ITAAC 8.
19. ITAAC 10 in Table 3.10-1: To resolve inconsistencies between the DC and AC.
20. ITAAC 5 in Table 3.11-2: To remove unnecessary and ambiguous qualifying language in the AC.
21. ITAAC 2 in Table 3.12-2: To remove unnecessary and ambiguous qualifying language in the AC.
22. ITAAC 7 and 8 in Table 3.16-1: To make the scope of the ITAAC consistent among the DC, ITA, and AC.
23. ITAAC 9 in Table 3.16-1: To clarify the scope of the ITA.
24. ITAAC 10 in Table 3.16-1: To make the scope of the ITA and AC consistent with the DC.
25. ITAAC 2, 3, and 4 in Table 3.17-2: See explanation for ITAAC 2, 3, and 4 in Table 2.7-2.
26. ITAAC 2 and 3 in Table 3.18-2: See explanation for ITAAC 2, 3, and 4 in Table 2.7-2.

NuScale Response:

RAI 9681 Question 14.03-03 included two items to be addressed prior to a list of proposed revisions. This section address the two items.

NuScale Nonproprietary

NRC Item 1:

ITAAC 29 in Table 2.5-7 verifies that the MCR isolation switches are located in the remote shutdown station but it does not verify the functionality of the switches. Please explain how ITAAC 29 verifies that the MCR isolation switches actually isolate the manual MCR switches from the MPS in case of fire. If ITAAC 29 does not verify the functionality of the MCR isolation switches, please explain what changes to the existing ITAAC in Tier 1 would be necessary to verify the functionality of the MCR isolation switches through ITAAC. If the applicant believes that ITAAC are not necessary to verify the functionality of the MCR isolation switches, please explain this and please explain why an ITAAC is, nonetheless, necessary to verify the location of the MCR isolation switches.

NuScale Response to NRC Item 1:

ITAAC are not necessary to verify the functionality or the location of the MPS MCR isolation switches. The MCR isolation switches, when repositioned, function to isolate the MPS manual actuation switches in the main control room. This function does not establish and maintains safe shutdown conditions, and failure of this function does not prevent these conditions from being established. While there is not an explicit Design Commitment for the function, the functionality of these switches will be verified as part of Table 2.5-7 ITAAC 02.05.01. Accordingly, ITAAC 02.05.29 has been deleted.

NRC Item 2:

The design commitments listed in the design descriptions of DCA Part 2, Tier 1 are not consistent with the design commitments in the corresponding ITAAC tables. Although not identified in the attachment, the design commitments in the design descriptions of DCA Part 2, Tier 1 should be revised to be consistent with the design commitment in the ITAAC tables.

NuScale Response to NRC Item 2:

Design Commitments associated with the following ITAAC were revised to provide alignment between the Tier 1 Design Descriptions and the associated ITAAC tables:

  • Table 2.1-4 o 02.01.01 o 02.01.08 o 02.01.13 through 15 o 02.01.18 through 21 NuScale Nonproprietary

o 02.01.24

  • Table 2.2-3 o 02.02.03
  • Table 2.6-1 o 02.06.02 o 02.06.03
  • Table 3.1-2 o 03.01.01
  • Table 3.3-1 o 03.03.03
  • Table 3.6-2 o 03.06.02
  • Table 3.13-1 o 03.13.04
  • Table 3.16-1 o 03.16.01 through 05 Where the difference between the Design Commitment in the Design Description section of Tier 1 and the Design Commitment in the ITAAC table is exclusively the result of defining an abbreviation during the first use of the term in the document, the difference is intentional, and therefore no changes were made. For example, Section 2.1 contains the following Design Commitment:

The Nuscale Power Module ASME Code Class 2 piping systems and interconnected equipment nozzles are evaluated for leak-before-break (LBB).

In the associated ITAAC table, Table 2.4-1, the Design Commitment is written as:

The NuScale Power Module ASME Code Class 2 piping systems and interconnected equipment nozzles are evaluated for LBB.

The term leak-before-break is used in its entirety for the first usage, while the associated abbreviation is used thereafter.

RAI 9681 Additional Explanations The RAI included a set of additional explanations for the basis of the Staffs proposed revisions.

This section describes how each of the additional explanations were dispositioned.

NuScale Nonproprietary

1. The proposed definition for Approved design, and the proposed definition revisions for the terms ASME Code and Reconciliation were incorporated into Tier 1, Section 1.1.

The following terms were arranged alphabetically, as suggested, but unmodified:

o Common or Shared ITAAC o Module-Specific ITAAC o Type Test

2. Incorporated the proposed explanatory material into Tier 1, Section 1.2.4.
3. Proposed changes incorporated. Tier 2, Table 14.3-1 was also revised to be consistent with the incorporated changes.
4. Proposed changes incorporated.
5. Proposed changes incorporated.
6. Proposed changes partially incorporated. The proposed revision for Tier 1 Table 2.5-7 ITAAC 02.05.06 was slightly altered. The concern was that the Design Commitment, as proposed, could be misinterpreted to mean communications independence exists between the separation groups and their associated divisions. To avoid this potential confusion, the Design Commitment was divided into two distinct parts, which align with the Acceptance Criteria.
7. Proposed changes incorporated.
8. The proposed changes for the Design Commitment and Acceptance Criterion were partially incorporated. The proposed change to the ITA was unnecessary, and therefore not incorporated to remain consistent with similar ITA in Table 2.5-7. The proposed changes included changing "one of its protection channels" to "any of its protection channels." This makes the Design Commitment false, as placing all channels in bypass (which is not procedurally permitted) would prohibit the performance of a safety-related function. Additionally, the term "protection channel" was replaced with "separation group" for technical accuracy.
9. Proposed changes incorporated.
10. Proposed changes incorporated.
11. Proposed changes incorporated.
12. Proposed changes incorporated.
13. Proposed changes incorporated. Tier 2, Table 14.3-2 was also revised to be consistent with the incorporated changes.
14. Proposed changes incorporated.
15. Proposed changes incorporated.
16. Proposed changes incorporated.

NuScale Nonproprietary

17. Proposed changes incorporated. Tier 2, Table 14.3-2 was also revised to explicitly state the RBC wet hoist is included in the scope in support of deleting ITAAC 03.10.08.
18. Proposed changes incorporated. Tier 2, Table 14.3-2 was also revised to delete 03.10.08 wording.
19. Proposed changes incorporated.
20. Proposed changes incorporated.
21. Proposed changes incorporated.
22. Proposed changes incorporated.
23. Proposed changes incorporated.
24. Proposed changes incorporated.
25. Proposed changes incorporated.
26. Proposed changes incorporated.

RAI 9681 Proposed Changes In addition to the items to address and the additional explanations sections of the RAI, multiple sections and tables from Tier 1 were provided with proposed changes. This section describes how each of these proposed changes were dispositioned.

Multiple ITAAC were identified with table numbers referenced in the Acceptance Criteria, but not the associated Design Commitment and ITA. The proposal was made to add the table numbers to the Design Commitment and ITA, and that proposal was incorporated, for the following ITAAC:

  • Table 2.1-4 o 02.01.14 o 02.01.15 o 02.01.18 through 21
  • Table 2.8-2 o 02.08.01 o 02.08.06 o 02.08.08
  • Table 3.14-2 o 03.14.01 o 03.14.03 To ensure consistency, all ITAAC were reviewed to verify the use table numbers was applied to the Design Commitment and ITA when used in the Acceptance Criterion. Although not NuScale Nonproprietary

specifically proposed by the RAI, and as a result of this review, table numbers were added to the following ITAAC:

  • Table 2.1-4 o 02.01.01 through 03 o 02.01.05 o 02.01.08 through 10 o 02.01.13
  • Table 2.2-3 o 02.02.01 through 03 o 02.02.05
  • Table 2.5-7 o 02.05.11 o 02.05.13
  • Table 2.7-2 o 02.07.01 o 02.07.02
  • Table 2.8-2 o 02.08.02 through 05 o 02.08.07 o 02.08.09
  • Table 3.1-2 o 03.01.02 o 03.01.03
  • Table 3.2-2 o 03.02.01
  • Table 3.6-2 o 03.06.02
  • Table 3.14.2 o 03.14.02 NuScale Nonproprietary
  • Table 3.17-2 o 03.17.01 o 03.17.02
  • Table 3.18-2 o 03.18.01 o 03.18.02 The following proposed wording changes provided in the RAI, but not specifically identified in the additional explanations section of the RAI, were incorporated:
  • Tier 1, Section 1.2.4, last paragraph
  • Table 2.1-4 o 02.01.14 o 02.01.15 o 02.01.18 through 21 o 02.01.24
  • Table 2.2-3 o 02.02.05
  • Table 2.3-1 o 02.03.01 o 02.03.02, only the ITA change
  • Table 2.5-7 o 02.05.18 through 20 o 02.05.27
  • Table 2.8-2 o 02.08.01 o 02.08.06 o 02.08.07 o 02.08.08
  • Table 3.4-1 o 03.04.02 o 03.04.03 NuScale Nonproprietary
  • Table 3.6-2 o 03.06.02
  • Table 3.7-1 o 03.07.02, only the Design Commitment change
  • Table 3.10-1 o 03.10.04 through 06 o 03.10.09
  • Table 3.11-2 o 03.11.07 (Corresponding changes also made to Section 3.11.1, and Tier 2 Table 14.3.2.)

Not all of the changes proposed in the RAI were incorporated. The following is a list of those proposed changes, and a brief description as to why they were not incorporated:

  • Tier 1, Section 1.2.4: The word and was not added between design commitments and inspections because it is unnecessary.
  • Table 2.3-1, ITAAC 02.03.02: The acceptance criteria was not revised to add pressure instrumentation. The acceptance criteria already specifies CES inlet pressure instrumentation (PIT-1001/PIT-1019).
  • Table 3.1-2, ITAAC 03.01.01: The Acceptance Criteria was not revised as proposed.

The proposed phrase meets the air exfiltration assumed could be interpreted to mean equals the air exfiltration assumed. This ITAAC verifies the value used in the analysis was conservative. Therefore, demonstrating actual air exfiltration is less than the assumed value used in the analysis is the appropriate Acceptance Criteria. Additionally, the Design Commitment in this table was revised from meets the assumptions to does not exceed the assumptions to align with the wording used in the Design Commitment associated with this ITAAC in Section 3.1.1, Design Description.

  • Table 3.7-1, ITAAC 03.07.02: The proposed change to the Acceptance Criteria results in the elimination of an explicit requirement to test the installed FPS pumps. As such, incorporating the proposed change is inappropriate.
  • Table 3.14-2:

o ITAAC 03.14.01: The proposed change is to use the term Seismic Qualification Report instead of seismic record form. No basis was provided for this proposed change. Additionally, the same change was neither proposed for the second Acceptance Criterion for the same ITAAC (03.14.01), nor for the Acceptance NuScale Nonproprietary

Criteria of 02.08.01, which also uses the term seismic record form. The proposed change was not incorporated to maintain consistency.

o ITAAC 03.14.03: The proposed change was to remove the phrase used for processing gaseous radioactive waste from all three areas of the ITAAC. This phrase was specifically included in the ITAAC wording to clearly establish that not all RW-IIa are within scope, and some RW-IIa components were intentionally excluded from Table 3.14-1.

During the review of Tier 1 material associated with this RAI, the following additional changes were identified and incorporated:

  • Tier 1, Table 2.3-1: An editorial hyphen was added.
  • Tier 1, Section 2.7: The equipment IDs were removed from Section 2.7.1, Design Description, and Table 2.7-2. The equipment IDs were redundant to Table 2.7-1, and therefore unnecessary once reference to the table was added to the Design Commitments, ITA, and Acceptance Criteria. Tier 2 Table 14.2-38, Chemical and Volume Controls System Test #38, and Tier 2 Table 14.3-1 were revised to reflect the deletion of ITAAC 02.07.03 and 02.07.04.
  • Tier 1, Section 2.8:

o The scope of equipment portion of the Design Commitments associated with ITAAC 02.08.01 through 03 were deleted from Section 2.8.1, Design Description, and Table 2.8-2 because it is redundant to the information in the Tier 1 System Description. This information remains in the System Description portion of Tier 1 Section 2.8.1 and Tier 2 Table 14.3-1.

o The words located in a harsh environment were deleted from the Design Commitments associated with ITAAC 02.08.09 in Section 2.8.1 and Table 2.8-2 because they were redundant to words already included in the Design Commitments.

  • Tier 1, Section 3.8: Because the actions for alternative (remote) shutdown are taken in the MPS equipment rooms in the Reactor Building and not at operator workstations in the remote shutdown station (RSS), ITAAC to verify normal and emergency illumination levels at the RSS are not required. Table 3.8-1, ITAAC 03.08.03 verifies emergency lighting for the activities in the MPS equipment rooms. In this same table, ITAAC 03.08.01 and 03.08.02 were revised to remove the RSS reference. Section 3.8.1 and Tier 2 Table 14.3.2 were revised to remove the reference to the RSS. Tier 2, Table 14.2-60, Plant Lighting System Test #60, was revised to remove the ITAAC reference from the RSS lighting component level tests.

NuScale Nonproprietary

  • Tier 1, Section 3.9: The equipment IDs were removed from Section 3.9.1, Design Description, and Table 3.9-2. The equipment IDs were redundant to Table 3.9-1, and therefore unnecessary once reference to the table was added to the Design Commitments, ITA, and Acceptance Criteria. Tier 2 Tables 14.2-9, Auxiliary Boiler System Test # 9, and 14.2-36, Gaseous Radioactive Waste System Test #36, and Tier 2 Table 14.3-2 were revised to reflect the deletion of ITAAC 03.09.05, 03.09.06 and 03.09.09.
  • Tier 1, Section 3.14:

o The scope of equipment portion of the Design Commitments associated with ITAAC 03.14.01 and 03.14.02 were deleted from Section 3.14.1, Design Description, and Table 3.14-2 because it is redundant to the information in the Tier 1 System Description. This information remains in the System Description portion of Tier 1 Section 3.14.1 and Tier 2 Table 14.3-2.

o Five module specific ITAAC were relocated to Table 3.14-2. This change was made based on the Tier 1 Section 1.1 definition for Common or Shared ITAAC, which includes analyses or other generic design and qualification activities that are identical for each NPM (e.g., environmental qualification of equipment).

For a multi-module plant, satisfactory completion of a common or shared ITAAC for the lead NPM shall constitute satisfactory completion of the common or shared ITAAC for associated NPMs. To ensure future users understand these five ITAAC are only required to be performed once, they were moved from Tier 1 Section 2 tables to Tier 1 Section 3 tables. Their corresponding Tier 2 Table 14.3-1 descriptions were moved to Tier 2 Table 14.3-2, accordingly. The following is the list of ITAAC that were moved and their new ITAAC numbers:

§ Table 02.01-4 ITAAC 02.01.22 is now Table 03.14-2 ITAAC 03.14.04

§ Table 02.08-2:

  • ITAAC 02.08.03 is now Table 03.14-2 ITAAC 03.14.05
  • ITAAC 02.08.05 is now Table 03.14-2 ITAAC 03.14.06
  • ITAAC 02.08.06 is now Table 03.14-2 ITAAC 03.14.07
  • ITAAC 02.08.08 is now Table 03.14-2 ITAAC 03.14.08
  • Tier 1, Section 3.17: The equipment IDs were removed from Section 3.17.1, Design Description, and Table 3.17-2. The equipment IDs were redundant to Table 3.17-1, and therefore unnecessary once reference to the table was added to the Design Commitments, ITA, and Acceptance Criteria. Tier 2 Table 14.2-24, Balance-of-Plant Drain System Test #24, and Tier 2 Table 14.3-2 were revised to reflect the deletion of ITAAC 03.17.03 and 03.17.04.

NuScale Nonproprietary

  • Tier 1, Section 3.18: The equipment IDs were removed from Section 3.18.1, Design Description, and Table 3.18-2. The equipment IDs were redundant to Table 3.18-1, and therefore unnecessary once reference to the table was added to the Design Commitments, ITA, and Acceptance Criteria. Tier 2 Table 14.2-24, Balance-of-Plant Drain System Test #24, and Tier 2 Table 14.3-2 were revised to reflect the deletion of ITAAC 03.18.03.

Impact on DCA:

Tier 1 Chapters 1, 2, 3, and Tier 2 Chapter 14 Sections 14.2 and 14.3 have been revised as described in the response above and as shown in the markup provided in this response.

NuScale Nonproprietary

NuScale Tier 1 Definitions 1.1 Definitions The definitions below apply to terms that may be used in the design descriptions and associated Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC).

Acceptance Criteria refers to the performance, physical condition, or analysis result for structures, systems, and components (SSC), or program that demonstrates that the design commitment is met.

Analysis means a calculation, mathematical computation, or engineering or technical evaluation. Engineering or technical evaluations could include, but are not limited to, comparisons with operating experience or design of similar SSC.

RAI 14.03-3 Approved design means the design as described in the updated final safety analysis report (UFSAR), including any changes to the final safety analysis report (FSAR) since submission to the NRC of the last update of the FSAR.

As-built means the physical properties of an SSC following the completion of its installation or construction activities at its final location at the plant site. In cases where it is technically justifiable, determination of physical properties of the as-built SSC may be based on measurements, inspections, or tests that occur prior to installation, provided that subsequent fabrication, handling, installation, and testing do not alter the properties.

RAI 14.03-3, RAI 14.03.03-8 ASME Code meansSection III of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, as endorsed in 10 CFR 50.55aincorporated by reference in 10 CFR 50.55a with specific conditions or in accordance with relief granted or alternatives authorized by the NRC pursuant to 10 CFR 50.55a, unless a different section of the ASME Code is specifically referenced.

ASME Code Data Report means a document that certifies that a component or system is constructed in accordance with the requirements of the ASME Code. This data is recorded on a form approved by the ASME.

RAI 14.03-3 Common or Shared ITAAC means ITAAC that are associated with common or shared SSC and activities that support multiple NPMs. This includes (1) SSC that are common or shared by multiple NPMs, and for which the interface and functional performance requirements between the common or shared SSC and each NPM are identical, or (2) analyses or other generic design and qualification activities that are identical for each NPM (e.g., environmental qualification of equipment). For a multi-module plant, satisfactory completion of a common or shared ITAAC for the lead NPM shall constitute satisfactory completion of the common or shared ITAAC for associated NPMs.

Component, as used for reference to ASME Code components, means a vessel, concrete containment, pump, pressure relief valve, line valve, storage tank, piping system, or core support structure that is designed, constructed, and stamped in accordance with the rules of the ASME Code. ASME Code Section III classifies a metal containment as a vessel.

Tier 1 1.1-1 Draft Revision 3

NuScale Tier 1 Definitions Design Commitment means that portion of the design description that is verified by ITAAC.

Design Description means that portion of the design that is certified. Design descriptions consist of a system description, system description tables, system description figures, and design commitments.

1.2.4 Implementation of Inspections, Tests, Analyses, and Acceptance Criteria Design commitments, inspections, tests, analyses, and acceptance criteria are provided in ITAAC tables with the following format:

No. Design Commitment Inspections, Tests, Analyses Acceptance Criteria RAI 14.03-3 Each commitment in the Design Commitment column of the ITAAC tables has one or more associated requirements for inspections, tests or analyses specified in the Inspections, Tests, Analyses column. Each inspection, test, or analysis has an associated acceptance criterion in the third column of the ITAAC tables that demonstrate that the Design Commitment in the first column has been met.

Inspections, tests, or analyses may be performed by the licensee or by its authorized vendors, contractors, or consultants.

Inspections, tests, or analyses may be

  • performed by more than a single individual or group.
  • implemented through discrete activities separated by time.
  • performed at any time prior to fuel load, including before issuance of the combined license for those ITAAC that do not require as-built equipment.
  • performed at a location other than the construction site.

Additionally, inspections, tests, or analyses may be performed as part of other activities such as construction inspections and preoperational testing. Therefore, inspections, tests, or analyses need not be performed as a separate or discrete activity.

If an acceptance criteria does not specify the temperature, pressure, or other conditions under which an inspection or test must be performed, then the inspection or test conditions are not constrained.

RAI 14.03-3 Many of the Acceptance Criteria state that a report or analysis exists and concludes that...
