License Conditions; ITAAC Introduction Part 8 - License Conditions; Inspections, Tests, Analyses &

Acceptance Criteria (ITAAC) 1.0 Introduction This document presents the information developed for the NuScale Power Plant US460 standard design Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC).

NuScale US460 SDAA 1 Revision 0

License Conditions; ITAAC Introduction 1.1 Definitions The definitions below apply to terms that may be used in the NuScale Power Plant Inspections, Tests, Analyses, and Acceptance Criteria and ITAAC Design Descriptions.

Acceptance Criteria refers to the performance, physical condition, or analysis result for structures, systems, and components (SSC), or programs that demonstrate 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.

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 SSC following the completion of their 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 before installation, provided that subsequent fabrication, handling, installation, and testing do not alter the properties.

ASME Code meansSection III of the American Society of Mechanical Engineers (ASME)

Boiler and Pressure Vessel Code, as incorporated 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. These data are recorded on a form approved by the ASME.

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.

Design Commitment means that portion of the ITAAC design description that is verified by ITAAC.

Inspect or Inspection means visual observations, physical examinations, or reviews of records based on visual observation or physical examination that compare (a) the SSC condition to one or more design commitments or (b) the program implementation elements to one or more program commitments, as applicable. Examples include walkdowns, configuration checks, measurements of dimensions, or nondestructive examinations. The terms, inspect and inspection, also apply to the review of Emergency Planning ITAAC requirements to determine whether ITAAC are met.

NuScale US460 SDAA 2 Revision 0

License Conditions; ITAAC Introduction The ITAAC are those Inspections, Tests, Analyses, and Acceptance Criteria identified in the combined license (COL) that if met by the licensee are necessary and sufficient to provide reasonable assurance that the facility has been constructed and will be operated in conformity with the license, the provisions of the Atomic Energy Act, as amended, and the Commission's rules and regulations.

Module-Specific or Unit-Specific ITAAC means ITAAC that are associated with SSC that are specific to and support operation of a single, individual NuScale Power Module (NPM). Module-specific ITAAC shall be satisfactorily completed for each NuScale Power Module.

NuScale Power Module is a collection of systems, sub-systems, and components that together constitute a modularized, movable, nuclear steam supply system. The NPM comprises a reactor core, a pressurizer (PZR), and two steam generators (SGs) integrated within a reactor pressure vessel (RPV) and housed in a compact steel containment vessel (CNV).

Reconciliation or Reconciled means the identification, assessment, and disposition of differences between a design feature as described in the UFSAR and an as-built plant design feature. For ASME Code piping systems, it is the reconciliation of differences between the design as described in the UFSAR and the as-built piping system. For structural features, it is the reconciliation of differences between the design as described in the UFSAR and the as-built structural feature.

Report, as used in the ITAAC table Acceptance Criteria column, means a document that verifies that the acceptance criteria of the subject ITAAC have been met and references the supporting documentation. The report may be a simple form that consolidates necessary information related to the closure package for supporting successful completion of the ITAAC.

Safe Shutdown Earthquake (SSE) Ground Motion is the site-specific vibratory ground motion for which safety-related SSC are designed to remain functional. The SSE for a site is a smoothed spectra developed to envelop the ground motion response spectra. The SSE is characterized at the free ground surface.

Shared or Common ITAAC means ITAAC that are associated with shared SSC and activities that support multiple NPMs. This includes (1) SSC that are shared by multiple NPMs, and for which the interface and functional performance requirements between the 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 shared ITAAC for the lead NPM shall constitute satisfactory completion of the shared ITAAC for associated NPMs.

Test means actuation or operation, or establishment of specified conditions, to evaluate the performance or integrity of as-built SSC, unless explicitly stated otherwise, to determine whether ITAAC are met.

NuScale US460 SDAA 3 Revision 0

License Conditions; ITAAC Introduction Type Test means a test on one or more sample components of the same type and manufacturer to qualify other components of the same type and manufacturer. A type test is not necessarily a test of an as-built SSC.

NuScale US460 SDAA 4 Revision 0

License Conditions; ITAAC Introduction 1.2 General Provisions 1.2.1 Systems Within the Scope of Inspections, Tests, Analyses, and Acceptance Criteria The results of the ITAAC screenings of SSC that are either fully or partially within the scope of the NuScale Power Plant standard design are provided in each systems ITAAC system description tables. These tables identify those SSC that are addressed by ITAAC.

ITAAC does not include systems that have been determined to not contain top-level design features or performance characteristics that require verification through ITAAC.

1.2.2 Inspections, Tests, Analyses, and Acceptance Criteria Design Descriptions The ITAAC design descriptions pertain only to the SSC of the standard design and not to their operation and maintenance after fuel load. In the event of an inconsistency between the ITAAC design descriptions and the FSAR information, the FSAR shall govern.

The ITAAC design descriptions consist of ITAAC system descriptions, ITAAC system description tables, ITAAC system description figures, and design commitments. The ITAAC system description tables and ITAAC system description figures are only used when appropriate. The ITAAC system description provides a concise description of the scope and top-level design features and performance characteristics of the SSC system functions. The ITAAC system description only describes those portions of the system or structure that are important to the top-level design features and performance characteristics of the system or structure. Design commitments are provided in numbered paragraphs that are used to develop the Design Commitment column in the ITAAC table. These commitments address top-level design features and performance characteristics such as:

  • seismic classification
  • ASME Code classification
  • equipment to be qualified for harsh environments
  • instrumentation and controls (I&C) equipment to be qualified for other than harsh environments When the term operate, operates, or operation is used with respect to equipment discussed in the acceptance criteria, it refers to the actuation or control of the equipment.

NuScale US460 SDAA 5 Revision 0

License Conditions; ITAAC Introduction 1.2.3 Interpretation of Inspections, Tests, Analyses, and Acceptance Criteria System Description Tables Cells with no values in ITAAC system description tables contain an N/A to denote that the cell is not applicable.

1.2.4 Interpretation of Inspections, Tests, Analyses, and Acceptance Criteria System Description Figures Figures are provided for some systems or structures with the amount of information depicted based on their safety significance. These figures may represent a functional diagram, general structural representation, or other general illustration. Unless specified, these figures are not indicative of the scale, location, dimensions, shape, or spatial relationships of as-built SSC. In particular, the as-built attributes of SSC may vary from the attributes depicted on these figures, provided that the top-level design features discussed in the ITAAC design description pertaining to the figure are not adversely affected. Valve position indications shown on system description figures do not represent a specific operational state.

The figure legends in FSAR Section 1.7 are used to interpret ITAAC system description figures.

1.2.5 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 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 one or more associated acceptance criteria in the third column of the ITAAC tables that demonstrate the Design Commitment in the first column is 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 before fuel load, including before issuance of the COL for those ITAAC that do not require as-built equipment.
  • performed at a location other than the construction site.

NuScale US460 SDAA 6 Revision 0

License Conditions; ITAAC Introduction 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 criterion 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.

Many of the Acceptance Criteria state that a report or analysis exists and concludes that.... When these words are used, it indicates that the ITAAC for that Design Commitment will be met when it is confirmed that appropriate documentation exists and the documentation shows that the Design Commitment is met.

For the acceptance criteria, appropriate documentation may be a single document or a collection of documents that show that the stated acceptance criteria are met. The following are examples of appropriate documentation:

  • design reports
  • test reports
  • inspection reports
  • analysis reports
  • evaluation reports
  • design and manufacturing procedures
  • certified data sheets
  • quality assurance records
  • calculation notes
  • equipment qualification data packages Conversion or extrapolation of test results from the test conditions to the design conditions may be necessary to satisfy an ITAAC. Suitable justification should be provided for any conversions or extrapolations of test results necessary to satisfy an ITAAC.

1.2.6 Acronyms and Abbreviations The acronyms and abbreviations contained in FSAR Table 1.1-1 are applicable to ITAAC.

NuScale US460 SDAA 8 Revision 0

Module-Specific Structures, Systems, and Components Inspections, Tests, License Conditions; ITAAC Analyses, and Acceptance Criteria (ITAAC) Design Descriptions and ITAAC 2.1 NuScale Power Module 2.1.1 Inspections, Tests, Analyses, and Acceptance Criteria Design Description ITAAC System Description The scope of this section is the NPM and its associated systems. The systems contained within the boundary of the NPM are the

  • reactor coolant system (RCS), including the RPV, PZR, SG, reactor vessel internals (RVI), and associated piping and valves. The RCS piping is located inside the CNV and connects to containment piping located outside the CNV via CNV nozzles. Steam generator system (SGS) piping is located inside the CNV.

The SGS steam piping connects to containment system (CNTS) steam piping located outside the CNV via CNV nozzles. The SGS feedwater piping connects to the decay heat removal system (DHRS) condenser condensate line inside the CNV.

  • CNTS, including the CNV and CIVs and associated piping. Containment piping is located outside the CNV with the exception of CNTS piping used for containment flooding and drain.
  • DHRS, including associated piping and valves. The DHRS steam piping is located outside the CNV and connects to containment piping outside the CNV. The DHRS condensate lines connect the DHR condensers to the SGS feedwater piping inside the CNV.

The NPM includes the pressure retaining structures of these systems because they are part of either the reactor coolant pressure boundary (RCPB) or the CNV pressure boundary. Therefore, the mechanical design and arrangement of the piping, CRDS, and NPM valves (emergency core cooling, reactor safety, and containment isolation) are included in this section.

The NPM performs the following safety-related functions that are verified by ITAAC:

  • The RCS supports the CNTS by supplying the RCPB and a fission product boundary via the RPV and other appurtenances.
  • The CRDS supports the RCS by maintaining the pressure boundary of the RPV.
  • The SGS supports the RCS by supplying part of the RCPB.
  • The ECCS supports the RCS by providing a portion of the RCPB for maintaining the RCPB integrity.
  • The CNTS supports the Reactor Building (RXB) by providing a barrier to contain mass, energy, and fission product release from a degradation of the RCPB.

  • The CNTS supports the RCS by providing structural support for the RPV.
  • The CNTS supports the ECCS by providing structural support of the trip and reset valves for the ECCS reactor vent valves (RVVs) and reactor recirculation valves (RRVs).
  • The CNTS supports the RCS by closing the CIVs for PZR spray, chemical and volume control system (CVCS) makeup, CVCS letdown, and RPV high point degasification when actuated by the module protection system (MPS) for RCS isolation.
  • The CNTS supports the RXB by providing a barrier to contain mass, energy, and fission product release by closure of the CIVs upon containment isolation signal.
  • The CNTS supports the DHRS by closing CIVs for main steam and feedwater and opening DHRS actuation valves when actuated by MPS for DHRS operation.
  • The ECCS supports the RCS by opening the ECCS reactor vent valves and RRVs when their respective trip valve is actuated by MPS.
  • The DHRS supports the RCS by opening the DHRS actuation valves on a DHRS actuation signal.
  • The CNTS supports the MPS by providing MPS actuation instrument information signals through the CNV.
  • The ECCS supports the RCS by providing boric acid to recirculated coolant from containment to ensure the core remains subcritical for design basis events.

ITAAC No. Discussion 02.01.01 As required by ASME Code Section III NCA-1210, each ASME Code Class 1, 2, and 3 component (including piping systems) of a nuclear power plant requires a Design Report in accordance with NCA-3550. NCA-3551.1 requires that the drawings used for construction be in agreement with the Design Report before it is certified and be identified and described in the Design Report. It is the responsibility of the N Certificate Holder to furnish a Design Report for each component and support, except as provided in NCA-3551.2 and NCA-3551.3. NCA-3551.1 also requires that the Design Report be certified by a registered professional engineer when it is for Class 1 components and supports, Class CS core support structures, Class MC vessels and supports, Class 2 vessels designed to NC-3200 (NC-3131.1), or Class 2 or Class 3 components designed to Service Loadings greater than Design Loadings.

A Class 2 Design Report shall be prepared for Class 1 piping NPS 1 or smaller that is designed in accordance with the rules of Subsection NC. NCA-3554 requires that any modification of any document used for construction, from the corresponding document used for design analysis, shall be reconciled with the Design Report.

An ITAAC inspection is performed of the NuScale Power Module ASME Code Class 1, 2, and 3 as-built piping system Design Reports and the ASME Code Class 1, 2, 3, and CS as-built component Design Reports to verify that the requirements of ASME Code Section III are met.

The inventory of the NuScale Power Module ASME Code Class, 1, 2, and 3 piping systems verified by ITAAC 02.01.01 is contained in Table 2.1-3. The inventory of the NuScale Power Module ASME Code Class, 1, 2, 3, and CS components verified by ITAAC 02.01.01 is contained in Table 2.1-4.

ITAAC No. Discussion 02.01.04 FSAR Section 3.6, Protection against Dynamic Effects Associated with Postulated Rupture of Piping, provides the design bases and criteria for the analysis required to demonstrate that safety-related SSC are not impacted by the adverse effects of a high-and moderate-energy pipe failure within the plant.

An ITAAC inspection is performed to verify that the as-built protective features credited in the reconciled Pipe Break Hazards Analysis Report such as pipe whip restraints, pipe whip or jet impingement barriers, jet impingement shields, or guard pipe have been installed in accordance with design drawings of sufficient detail to show the existence and location of the protective hardware. The as-built inspection is intended to verify that changes to postulated pipe failure locations and protective features or protected equipment made during construction do not adversely affect the safety-related functions of the protected equipment.

02.01.05 Quality Control inspection hold points are used to ensure the as-built ECCS supplemental boron dissolvers and CNV lower mixing tubes are installed consistent with their associated installation specifications, and therefore capable of performing their safety functions.

To demonstrate the acceptance criterion for ITAAC 02.01.05 is satisfied and the associated design commitment fully met, a report will exist and conclude Quality Control inspection hold points exist and have been completed in accordance with the Quality Assurance Program for the ECCS supplemental boron dissolvers and CNV lower mixing tubes.

02.01.06 The CNTS electrical penetrations listed in Table 2.1-5 may be one of two types, one with or without a circuit interrupting device. An ITAAC confirms that each type of penetration is evaluated to confirm it can withstand its maximum fault current.

A circuit interrupting device coordination analysis confirms and concludes in a report that the as-built containment electrical penetration assembly listed in Table 2.1-5 that has a circuit interrupting device can withstand fault currents for the time required to clear the fault from its power source.

FSAR Section 8.3.1 discusses electrical penetration assemblies that are not equipped with protection devices whose maximum fault current in these circuits would not damage the electrical penetration assembly if that fault current is available indefinitely. An analysis of a CNTS as-built containment penetration without a circuit interrupting device confirms and concludes in a report that the maximum fault current is less than the current carrying capability of the CNTS containment electrical penetration.

02.01.07 FSAR Section 6.2.6, Containment Leakage Testing, provides a discussion of the leakage testing requirements of the CNV, which serves as an essentially leak-tight barrier against the uncontrolled release of radioactivity to the environment. As discussed in FSAR Section 6.2.6, the NuScale CNV is exempted from the integrated leak rate testing specified in the General Design Criterion (GDC) 52.

In accordance with FSAR Table 14.2-38, a preoperational test demonstrates that the leakage rate for local leak rate tests (Type B and Type C) for pressure containing or leakage-limiting boundaries and CIVs meet the leakage acceptance criterion of 10 CFR Part 50 Appendix J.

02.01.08 FSAR Section 6.2.4, Containment Isolation System, provides a discussion of how the CNTS containment isolation valves close within the required closure time after receipt of a containment isolation signal to meet containment isolation requirements following a radiological release in the CNV.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that each automatic CIV listed in Table 2.1-5 travels from the full open to full closed position in less than or equal to the time listed in FSAR Table 6.2-5 after receipt of a containment isolation signal.

02.01.09 FSAR Section 6.2.4, provides a discussion of the isolation valves outside containment that are located as close to the containment as practical.

An ITAAC inspection is performed to verify the length of piping between each containment penetration and its associated outboard CIVs is less than or equal to the length identified in Table 2.1-3.

ITAAC No. Discussion 02.01.10 FSAR Section 8.3.1, Alternating Current Power Systems, discusses the electrical design requirements for EPAs with respect to RG 1.63.

An analysis determines the required design electrical rating needed to power the design loads of each NuScale Power Module CNTS containment EPA listed in Table 2.1-5.

An ITAAC inspection is performed to verify that the electrical rating of each NuScale Power Module CNTS containment EPA listed in Table 2.1-5 is greater than or equal to the required design electrical rating. This ITAAC inspection may be performed any time after manufacture of the CNTS containment EPAs.

02.01.11 Quality Control inspection hold points are used to ensure the as-built ECCS valves, CIVs, DHRS actuation valves, and their associated hydraulic lines are installed consistent with their associated installation specifications, and therefore capable of performing their safety functions. To demonstrate the acceptance criterion for ITAAC 02.01.26 is satisfied and the associated design commitment fully met, a report will exist and conclude the following:

1) Quality Control inspection hold points exist and have been completed in accordance with the Quality Assurance Program for each of the following attributes of the ECCS valves, CIVs, and DHRS actuation valves:
a. geometric configuration
b. orientation
c. accessibility
2) Quality Control inspection hold points exist and have been completed in accordance with the Quality Assurance Program for each of the following attributes of routing of the hydraulic lines of the ECCS valves, CIVs, and DHRS actuation valves:
a. twisting
b. bend radii
c. crimping
d. support
e. line separation
f. safe shipment feature removal 02.01.12 FSAR Section 6.2.6, Containment Leakage Testing, provides the test requirements for a preservice design pressure leakage test of the CNV. The test verifies no observed leakage at the CNV bolted flange connections under design pressure.

The test may be performed any time after manufacture of the CNV, before the NPM being placed into service.

02.01.13 The CNTS remotely-operated CNTS containment isolation valves are tested by remote operation to demonstrate the capability to perform their function to transfer open and transfer closed under preoperational temperature, differential pressure, and flow conditions.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that the CNTS remotely operated CNTS containment isolation valves listed in Table 2.1-4 stroke fully open and fully closed by remote operation under preoperational test conditions.

Preoperational test conditions are established that approximate design-basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

For the first NPM only, a test is conducted under preoperational test conditions that approximate design-basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations. The test is initiated with an initial RPV to CNV differential pressure greater than the inadvertent actuation block threshold pressure of 900 psid in accordance with FSAR Table 14.2-40 and demonstrates that the ECCS safety-related valves listed in Table 2.1-4 stroke fully open by remote operation. In accordance with FSAR Table 14.2-56, a test is performed that demonstrates that the ECCS safety-related valves listed in Table 2.1-4 stroke fully closed by remote operation.

For subsequent NPMs, a test is conducted at reduced pressure and temperature in accordance with FSAR Table 14.2-56 to demonstrate that the ECCS safety-related valves listed in Table 2.1-4 stroke fully open and fully closed by remote operation.

02.01.15 The DHRS safety-related valves are tested by remote operation to demonstrate the capability to perform their function to transfer open and transfer closed under preoperational temperature, differential pressure, and flow conditions.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that the DHRS safety-related valves listed in Table 2.1-4 stroke fully open and fully closed by remote operation under preoperational test conditions.

Preoperational test conditions are established that approximate design basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

02.01.16 FSAR Section 9.1.5, Overhead Heavy Load Handling Systems, discusses that the CNV top support structure represent a single-failure-proof lifting device in accordance with the requirements of ANSI N14.6.

As described in FSAR Section 9.1.5, the CNV top support structure is load tested to 150 percent (+5%,

-0%) of the manufacturer's rating in accordance with ANSI N14.6. As part of the rated load test, critical areas of the CNV top support structure, including load-bearing welds, will undergo nondestructive testing as required by ANSI N14.6.

This ITAAC test may be performed any time after manufacture of the CNV top support structure (at the factory or later).

02.01.17 FSAR Section 9.1.5 discusses that the CNV top support structure represents a single-failure-proof lifting device in accordance with the requirements of ANSI N14.6.

An ITAAC inspection is performed of the CNV top support structure to verify the existence of dual load paths.

This ITAAC inspection may be performed any time after manufacture of the CNV top support structure (at the factory or later).

ITAAC No. Discussion 02.01.18 The CNTS safety-related hydraulic-operated valves are tested to demonstrate the capability to perform their function to fail to or maintain their safety-related position on loss of motive power under preoperational temperature, differential pressure, and flow conditions.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that each CNTS safety-related hydraulic-operated valves listed in Table 2.1-4 repositions to or maintains its safety-related position on loss of motive power (electric power to the valve actuating solenoid(s) is lost, or hydraulic pressure to the valve(s) is lost).

Preoperational test conditions are established that approximate design-basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

02.01.19 The ECCS safety-related RRVs and RVVs are tested to demonstrate the capability to perform their function to fail to or maintain their safety-related position on loss of electrical power under preoperational temperature, differential pressure, and flow conditions.

For the first NPM only, a test is conducted under preoperational test conditions that approximate design-basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

For subsequent NPMs a test is conducted at reduced pressure and temperature in accordance with FSAR Table 14.2-56 to demonstrate that each ECCS safety-related valve listed in Table 2.1-4 fails open on loss of electrical power to its corresponding trip valve.

02.01.20 The DHRS safety-related hydraulic-operated valves are tested to demonstrate the capability to perform their function to fail to or maintain their safety-related position on loss of motive power under preoperational temperature, differential pressure, and flow conditions.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that each DHRS safety-related hydraulic-operated valves listed in Table 2.1-4 fails open loss of motive power (electric power to the valve actuating solenoid(s) is lost, or hydraulic pressure to the valve(s) is lost).

Preoperational test conditions are established that approximate design basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

02.01.21 The CNTS safety-related check valves are tested to demonstrate the capability to perform their function to transfer open and transfer closed (under forward and reverse flow conditions, respectively) under preoperational temperature, differential pressure, and flow conditions. Check valves are tested in accordance with the requirements of the ASME OM Code, ISTC-5220, Check Valves.

ITAAC Discussion No.

02.05.01 MPS Design and Implementation FSAR Section 7.2.1, Quality, discusses the software life-cycle phases for the MPS. The purpose is to verify software implementation based on licensing commitments to 10 CFR Part 50, Appendix A, GDC 1 (Quality), Appendix B (Quality Assurance Criteria), RGs 1.28, 1.152, 1.168, 1.169, 1.170, 1.171, 1.172, and 1.173, and the associated IEEE standards. The licensee shall perform analyses for each phase and generate technical reports to conclude that the life-cycle phases are implemented per the licensing commitments. The requirements of IEEE Std 829-2008 "IEEE Standard for Software and System Test Documentation," are tailored to the NuScale I&C development life cycle, which is different than that of the conceptual waterfall life cycle listed in RG 1.152.

The ITAAC verifies that output documentation of each software life-cycle phase satisfies the requirements of that phase for the MPS, and that software are implemented per licensing commitments to 10 CFR Part 50, Appendix A, GDC 1 (Quality), Appendix B (Quality Assurance Criteria), RGs 1.28, 1.152, 1.168, 1.169, 1.170, 1.171, 1.172, and 1.173, and the associated IEEE standards.

Tunable Parameters FSAR Section 7.2.9, Control of Access, Identification, and Repair, discusses the protective measures that prevent modification of the MPS tunable parameters without proper configuration and authorization.

Guidance on this issue is provided in DI&C-ISG-04, "Highly-Integrated Control Rooms - Communications Issues," under interdivisional communications, staff position 10.

A test demonstrates that protective measures restrict modification to the MPS tunable parameters without proper configuration and authorization. This test will be performed by attempting to modify the tunable parameters with the MPS not in the correct configuration or without authorization.

Communication Independence FSAR Section 7.1.2, Independence, discusses the communication independence between redundant Class 1E digital communication system divisions. The purpose is to verify proper data isolation between redundant divisions. Requirements for independence are given in IEEE Std. 603-1991. Guidance for providing independence between redundant divisions of the Class 1E digital communication system is provided in Digital I&C Interim Staff Guidance (ISG) 04.

The MPS initiates an automatic ESF actuation signal when the associated plant condition(s) exist.

A test demonstrates that an automatic ESF actuation signal is automatically initiated for each of the ESF functions listed in Table 7.1-4.

The actuation of ESFs equipment is not required for this test. The verification of the existence of an ESF actuation signal is accomplished using MCR displays.

RTBs Open, Automatic Trip FSAR Section 7.1.1, Design Bases and Additional Design Considerations, describes automatic and manual reactor trips, variables that are monitored to provide input into automatic reactor trip signals, and the features of the RTS. The reactor trip functions are listed in FSAR Table 7.1-3: Reactor Trip Functions.

The reactor trip logic for the monitored variables is provided in figures in FSAR Section 7.1.1.

The MPS initiates an automatic reactor trip signal for the reactor trip functions when the associated plant condition(s) exist.

A test demonstrates that the RTBs open when any one of the automatic reactor trip functions is initiated from the MCR. The RTBs are only opened once to satisfy this test objective.

RTBs Open, Manual Trip FSAR Section 7.1.1, Design Bases and Additional Design Considerations, describes automatic and manual reactor trips, variables that are monitored to provide input into automatic reactor trip signals, and the features of the RTS. A manual reactor trip is one of the MPS manually actuated functions.

A test demonstrates that the RTBs open when a reactor trip is manually initiated from the MCR.

Reactor Trip Logic FSAR Section 7.1.1, Design Bases and Additional Design Considerations, describes that consistent with GDC 23, the MPS has sufficient functional diversity to prevent the loss of a protection function, to fail into a safe state or into a state demonstrated to be acceptable if conditions such as disconnection of the system, loss of power, or postulated adverse environments are experienced.

A test demonstrates that when the loss of electrical power is detected in a separation group of the MPS that separation group fails to a safe state resulting in a reactor trip state for that separation group.

ESF Trip Logic Guidance provided in Design Specific Review Standard Section 7.2.3, Reliability, Integrity, and Completion of Protective Action, states that the design incorporate protective measures that provide for I&C safety systems to fail in a safe state, or into a state that is demonstrated to be acceptable on some other defined basis, if conditions such as disconnection of the system, loss of power, or adverse environments, are experienced.

FSAR Section 7.1.1, Design Bases and Additional Design Considerations, describes that consistent with GDC 23, the MPS has sufficient functional diversity to prevent the loss of a protection function, to fail into a safe state or into a state demonstrated to be acceptable if conditions such as disconnection of the system, loss of power, or postulated adverse environments are experienced. For an ESF function this predefined safe state may be that the actuated component remains as-is.

A test demonstrates that when the loss of electrical power is detected in a separation group of the MPS that separation group fails to a safe state for that separation group.

MPS Interlocks FSAR Section 7.2.4, Operating and Maintenance Bypasses, describes MPS operating bypasses for reactor trip functions and ESF actuations. The operating bypasses are applied automatically when plant conditions dictate that the safety function is not needed, or that the safety function prevents proper plant operation at a specific mode of operation.

A test demonstrates that the MPS interlocks listed in FSAR Table 7.1-5 automatically establish an operating bypass for the specified reactor trip or ESF actuations when a real or simulated signal simulates that the associated interlock condition is met; and are automatically removed when the real or simulated signal simulates that the associated permissive condition is no longer satisfied.

MPS Permissives FSAR Section 7.2.4, Operating and Maintenance Bypasses, describes MPS operating bypasses for reactor trip functions and ESF actuations. The only manual operating bypasses used for the design use a permissive in conjunction with the manual bypass in order to achieve the function of the bypass.

A test demonstrates that the MPS permissives listed in FSAR Table 7.1-5 allow the manual bypass of the specified reactor trip or ESF actuations when a real or simulated signal simulates that the associated permissive condition is met; and are automatically removed when the real or simulated signal simulates that the associated permissive condition is no longer satisfied.

MPS Overrides FSAR Section 7.2.4, Operating and Maintenance Bypasses, describes MPS operating bypasses for reactor trip functions and ESF actuations. For beyond design-basis events and for a limited number of actuated equipment, a safety-related Override switch can be used to prioritize a nonsafety signal over certain automatic signals.

A test demonstrates that the MPS overrides listed in FSAR Table 7.1-5 are established when the manual Override switch is active and a real or simulated RT-1 interlock is established.

Maintenance Bypass FSAR Section 7.2.4, Operating and Maintenance Bypasses, describes the MPS maintenance bypass operation mode. An individual protection channel can be placed in a maintenance bypass operation mode to allow manual testing and maintenance during power operation, while ensuring that the minimum redundancy required by the Technical Specifications is maintained. The reactor trip functions are listed in FSAR Table 7.1-3: Reactor Trip Functions. The ESFs functions are listed in FSAR Table 7.1-4:

Engineered Safety Feature Actuation System Functions.

A test demonstrates that with a safety function module out of service switch activated, the safety function is placed in trip or bypass based on the position of the safety function module trip/bypass switch. Each separation group of the reactor trip functions listed in FSAR Table 7.1-3 and each separation group of the ESFs signals listed in FSAR Table 7.1-4 is tested by placing the separation group in maintenance bypass.

02.05.02 FSAR Sections 7.1.2, Independence, discusses the independence of the MPS Class 1E I&C current-carrying circuits per the guidance of RG 1.75, which endorses IEEE Std. 384-1992. Physical separation is provided to maintain the independence of Class 1E I&C current-carrying circuits so that the safety functions required during and following any design basis event can be accomplished. Minimum separation distance (as defined in IEEE Std. 384-1992), or barriers or any combination thereof may achieve physical separation as specified in IEEE Std. 384-1992.

Separate ITAAC inspections are performed to verify the independence provided by physical separation and the independence provided by electrical isolation. This ITAAC verifies the independence of Class 1E current-carrying circuits by physical separation. An ITAAC inspection is performed of physical separation of the MPS Class 1E current-carrying circuits. The physical separation ITAAC inspection results verify that the following physical separation criteria are met:

Physical separation between redundant divisions of the MPS Class 1E I&C current-carrying circuits is provided by a minimum separation distance, or by barriers (where the minimum separation distances cannot be maintained), or by a combination of separation distance and barriers; and such physical separation satisfies the criteria of RG 1.75. The configuration of each as-built barrier agrees with its associated as-built drawing.

Physical separation between the MPS Class 1E I&C current-carrying circuits and non-Class 1E I&C current-carrying circuits is provided by a minimum separation distance, or by barriers (where the minimum separation distances cannot be maintained), or by a combination of separation distance and barriers; and such physical separation satisfies the criteria of RG 1.75. The configuration of each as-built barrier agrees with its associated as-built drawing.

02.05.03 FSAR Sections 7.1.2, Independence, discusses the independence of the MPS Class 1E I&C circuits per the criteria of RG 1.75, which endorses IEEE Std. 384-1992. Electrical isolation is provided between the redundant divisions of the MPS Class 1E I&C circuits, and between Class 1E I&C circuits and non-Class 1E I&C circuits by Class 1E isolation devices so a failure in an I&C circuit does not prevent safety-related function completion in a different Class 1E I&C circuit.

An ITAAC inspection is performed to verify the following electrical isolation criteria are met: (1) Class 1E electrical isolation devices that satisfy the criteria of RG 1.75 are installed between redundant divisions of the MPS Class 1E I&C circuits. (2) Class 1E electrical isolation devices that satisfy the criteria of RG 1.75 are installed between the MPS Class 1E I&C circuits and non-Class 1E I&C circuits.

02.05.04 FSAR Sections 7.1.2, Independence, discusses the independence of MPS Class 1E circuits per the criteria of RG 1.75, which endorses IEEE Std. 384-1992. Electrical isolation is provided between Class 1E circuits and non-Class 1E circuits by Class 1E isolation devices so a failure in a non-Class 1E circuit does not prevent the safety-related function completion in the Class 1E circuit.

The ITAAC verifies that: (1) an equipment qualification data report exists for the Class 1E isolation devices, and (2) the equipment qualification data report concludes that the Class 1E isolation devices performs its safety-related function under the design basis environmental conditions specified in the equipment qualification data report.

02.05.05 FSAR Section 7.1.2, Independence, discusses the communication independence between Class 1E digital communication systems and non-Class 1E digital communication systems. The purpose is to verify that logical or software malfunction of the nonsafety-related system cannot affect the functions of the safety system. Requirements for independence are given in IEEE Std. 603-1991. Guidance for providing independence between the Class 1E digital communication system and non-Class 1E digital communication systems is provided in Digital Instrumentation and Controls ISG 04.

A vendor test demonstrates that independence between the Class 1E MPS and non-Class 1E digital systems is provided.

02.05.06 FSAR Section 7.1.1, Design Bases and Additional Design Considerations, describes automatic and manual ESFs actuations, variables that are monitored to provide input into automatic ESFs signals, and the features of the ESF systems. The ESFs functions are listed in FSAR Table 7.1-4: Engineered Safety Feature Actuation System Functions. The ESFs logic for the monitored variables is provided in figures in FSAR Section 7.1.

The MPS initiates an automatic ESF actuation signal for the functions listed in FSAR Table 7.1-4 when the associated plant condition(s) exist.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that ESF equipment automatically actuates to perform its safety-related function listed in FSAR Table 7.1-4 upon an injection of a single simulated MPS signal.

02.05.07 FSAR Section 7.1.1, Design Bases and Additional Design Considerations, describes manual ESFs actuation variables that are monitored to provide input into automatic ESFs signals, and the features of the ESF system. The ESFs functions that can be manually actuated are shown in figures in FSAR Section 7.1.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that the MPS actuates the ESF equipment to perform its safety-related function listed in FSAR Table 7.1-4 when manually initiated.

02.05.08 FSAR Section 7.2.3, Reliability, Integrity, and Completion of Protective Action, describes compliance with requirements for completion of protective actions, which requires that, once initiated, the reactor trip and ESF proceed to completion and remain in their required position/condition until the actuation system is reset and operator action is taken. IEEE 603-1991 Clause 5.2 states that The safety systems shall be designed so that, once initiated automatically or manually, the intended sequence of protective actions of the execute features shall continue until completion. Deliberate operation action shall be required to return the safety systems to normal. This requirement shall not preclude the use of equipment protective devices identified in [Clause] 4.11 of the design basis or the provisions for deliberate operator interventions. Seal-in of individual channels is not required."

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that

i. upon an MPS reactor trip signal listed in FSAR Table 7.1-3, the RTBs open and the RTBs do not automatically close when the MPS reactor trip signal clears.

ii. upon an MPS ESF actuation signal listed in FSAR Table 7.1-4, the ESF equipment actuates to perform its safety-related function and continues to maintain its safety-related position and perform its safety-related function when the MPS ESF actuation signal clears.

02.05.09 FSAR Section 7.2.12, Automatic and Manual Control, describes the signals and initiating logic for each reactor trip and ESF actuation.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that the measured time for the reactor trip functions listed in FSAR Table 7.1-3 is less than or equal to the maximum values assumed in the accident analyses.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that the measured time for the ESF functions listed in FSAR Table 7.1-4 is less than or equal to the maximum values assumed in the accident analyses.

Technical Specification SR 3.0.1 bases states that surveillances may be performed by means of any series of sequential, overlapping, or total steps provided the entire surveillance is performed within the specified frequency. The technical specification bases also describe an allowance for response time to be verified by any series of sequential, overlapping, or total channel measurements.

02.05.10 FSAR Section 7.2.4, Operating and Maintenance Bypasses, describes the MPS operating bypasses.

These bypasses either automatically or manually block certain protective actions that otherwise prevent mode changes during plant operation. Indication is provided in the control room if some part of the system has been bypassed or taken out of service.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that each operational MPS manual or automatic bypass is indicated in the MCR.

02.05.11 FSAR Section 7.2.4, Operating and Maintenance Bypasses, describes the MPS maintenance bypass operation mode. An individual protection channel can be placed in a maintenance bypass operation mode to allow manual testing and maintenance during power operation, while ensuring that the minimum redundancy required by the technical specifications is maintained. FSAR Section 7.2.4 discusses the status indication of MPS maintenance bypasses placed in maintenance bypass operation mode.

In accordance with FSAR Table 14.2-56, a preoperational test demonstrates that each MPS maintenance bypass is indicated in the MCR.

02.05.12 This ITAAC is intended to address self-testing features credited towards surveillance or other operational testing. Given the nature of this ITAAC, it is acceptable to verify ITAAC completion during the factory acceptance testing. Self-testing features include, but are not limited to, watchdog timers, automated channel checks, and signal input comparisons.

FSAR Section 7.2.15, Capability for Test and Calibration, discusses the self-testing features of the MPS, including the types of faults that should be detected, the system responses to such faults, the required response times, and the ability for alarms and displays in the MCR to provide indication of such faults' existence.

These tests of the MPS self-testing features ensure that a) faults requiring detection are detected, b) the system responds appropriately to each fault based on the type of fault, c) the response occurs within a sufficient time frame to ensure safety function is not lost, and d) that alarms and indications in the MCR indicate the type of fault present.

A vendor test demonstrates and a report exists and concludes that

  • self-testing features verify that faults requiring detection are detected.
  • self-testing features verify that upon detection, the system responds according to the type of fault.
  • self-testing features verify that faults are detected and responded within a sufficient time frame to ensure safety function is not lost.
  • self-testing features verify that detected faults are indicated by alarms and displays.

02.05.13 FSAR Section 7.1.1, Design Bases and Additional Design Considerations, and FSAR Section 7.2.13, Displays and Monitoring, describe the PAM Type B and C displays and alarms indicated on the SDIS displays in the MCR. The PAM Type B and C variables are developed in accordance with the guidance in RG 1.97, "Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants," which endorses (with certain clarifying regulatory positions specified in Section C of this guide) IEEE Std. 497-2016, "IEEE Standard Criteria for Accident Monitoring Instrumentation for Nuclear Power Generating Stations."

In accordance with FSAR Table 14.2-59, a preoperational test demonstrates the ability to retrieve and display the various PAM Type B and C parameters at the as-built safety display indication displays in the MCR. The intent is to verify that the displays function during testing of the integrated as-built system; however, separate testing of the actual operation of the PAM displays using simulated signals may be acceptable where this is not practicable.

Physical separation is provided to maintain the independence of Class 1E I&C current-carrying circuits so that the safety functions required during and following any design basis event can be accomplished. Minimum separation distance (as defined in IEEE Std. 384-1992), or barriers or any combination thereof may achieve physical separation as specified in IEEE Std. 384-1992.

Separate ITAAC inspections are performed to verify the independence provided by physical separation and the independence provided by electrical isolation. This ITAAC verifies the independence of Class 1E current-carrying circuits by physical separation. An ITAAC inspection is performed of physical separation of the NMS Class 1E current-carrying circuits. The physical separation ITAAC inspection results verify that the following physical separation criteria are met:

i. Physical separation between redundant divisions of the NMS Class 1E I&C current-carrying circuits is provided by a minimum separation distance, or by barriers (where the minimum separation distances cannot be maintained), or by a combination of separation distance and barriers; and such physical separation satisfies the criteria of RG 1.75. The configuration of each as-built barrier agrees with its associated as-built drawing.

ii. Physical separation between the NMS Class 1E I&C current-carrying circuits and non-Class 1E I&C current-carrying circuits is provided by a minimum separation distance, or by barriers (where the minimum separation distances cannot be maintained), or by a combination of separation distance and barriers. The configuration of each as-built barrier agrees with its associated as-built drawing.

02.06.03 FSAR Section 7.1.2, Independence, discusses the independence of the NMS Class 1E I&C circuits per the criteria of RG, which endorses IEEE Std. 384-1992. Electrical isolation is provided between the redundant divisions of the NMS Class 1E I&C circuits, and between Class 1E I&C circuits and non-Class 1E I&C circuits by Class 1E isolation devices so a failure in an I&C circuit does not prevent safety-related function completion in a different Class 1E I&C circuit.

An ITAAC inspection is performed to verify the following electrical isolation criteria are met:

i. Class 1E electrical isolation devices that satisfy the criteria of RG 1.75 are installed between redundant divisions of the NM system Class 1E I&C circuits.

ii. Class 1E electrical isolation devices that satisfy the criteria of RG 1.75 are installed between the NMS Class 1E I&C circuits and non-Class 1E I&C circuits.

03.01.01 Testing is performed on the CRE in accordance with RG 1.197, Demonstrating Control Room Envelope Integrity at Nuclear Power Reactors, Revision 0, to demonstrate that air exfiltration from the CRE is controlled. RG 1.197 allows two options for CRE testing; either integrated testing (tracer gas testing) or component testing. FSAR Section 6.4, Control Room Habitability, describes the testing requirements for the CRE habitability program and provides the maximum air exfiltration allowed from the CRE.

In accordance with FSAR Table 14.2-15, a preoperational test using the tracer gas test method demonstrates that the air exfiltration from the CRE does not exceed the assumed unfiltered leakage rate for the dose analysis. Tracer gas testing in accordance with ASTM E741 will be performed to measure the unfiltered in-leakage into the CRE with the CRHS operating.

03.01.02 The CRHS valves are tested by remote operation to demonstrate the capability to perform their function to transfer open and transfer closed under preoperational temperature, differential pressure, and flow conditions.

In accordance with FSAR Table 14.2-15, a preoperational test demonstrates that each CRHS valve listed in Table 3.1-3 strokes fully open and fully closed by remote operation under preoperational test conditions.

Preoperational test conditions are established that approximate design-basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

03.01.03 The CRHS solenoid-operated valves are tested to demonstrate the capability to perform their function to fail open on loss of motive power under preoperational temperature, differential pressure, and flow conditions.

In accordance with FSAR Table 14.2-15 a preoperational test demonstrates that each CRHS solenoid-operated valve listed in Table 3.1-3 repositions to the open position on loss of motive power (electric power to the valve actuating solenoid(s) is lost, or pneumatic pressure to the valve(s) is lost).

Preoperational test conditions are established that approximate design basis temperature, differential pressure, and flow conditions to the extent practicable, consistent with preoperational test limitations.

03.01.04 FSAR Section 6.4.4, Design Evaluation, discusses the thermal mass of the CRB and its contents limit the temperature increase as shown in Table 6.4-2 within the CRE within an acceptable range for the first 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> following a DBA.

FSAR Table 6.4-1, Control Room Habitability System Design Parameters, provides the required positive pressure in the MCR relative to the adjacent areas.

In accordance with FSAR Table 14.2-15, a preoperational test demonstrates that the CRHS maintains a positive pressure of greater than or equal to 1/8 inches water gauge in the MCR relative to adjacent areas, while operating in a DBA alignment.

03.02.01 The CRVS control room envelope isolation dampers are tested to demonstrate the capability to perform their function to fail to the closed position on loss of motive power.

In accordance with FSAR Table 14.2-16, a preoperational test demonstrates that each CRVS air-operated CRE isolation damper listed in Table 3.2-3 repositions to the closed position on loss of motive power (electric power to the valve actuating solenoid is lost, or pneumatic pressure to the damper is lost).

Preoperational test conditions are established that approximate design differential pressure conditions to the extent practicable, consistent with preoperational test limitations. A manual signal, actual automatic signal, or simulated automatic signal may be used to operate the valves because the control logic of the valves is not being verified by this ITAAC.

03.02.02 FSAR Section 9.4.1.2, System Description, discusses the operation of the CRVS, which maintains a positive pressure in the CRB relative to the outside environment. This is consistent with the requirements of 10 CFR Part 20, Subparts E and H and 10 CFR Part 50, Appendix I.

In accordance with FSAR Table 14.2-16 a preoperational test demonstrates that the CRVS will maintain a positive pressure of greater than or equal to 1/8 inches water gauge in the CRB relative to the outside environment, while operating in a normal operating alignment.

03.02.03 FSAR Section 9.4.1, Control Room Area Ventilation System, provides a discussion of how the CRVS maintains the hydrogen concentration levels in the CRB battery rooms containing batteries below one percent by volume.

In accordance with FSAR Table 14.2-16, a preoperational test demonstrates that the airflow capability of the CRVS maintains the hydrogen concentration levels in the CRB battery rooms containing batteries below one percent by volume.

03.07.01 FSAR Section 9.5.1, Fire Protection Program, discusses how the FPS meets the guidance provided by RG 1.189 and applicable NFPA standards. Two separate dedicated 100 percent capacity freshwater storage tanks are provided.

An ITAAC inspection is performed to verify that the minimum usable water volume of each firewater storage tank is greater than or equal to 300,000 gallons. If the storage tanks are also used as backup water sources for other non-fire emergencies, the ITAAC inspection verifies that the non-fire emergencies cannot drain the tank below the minimum dedicated useable water volume of 300,000 gallons required for firefighting.

03.07.02 FSAR Section 9.5.1, Fire Protection Program, discusses how the capacity of each FPS pump is adequate to supply the total flow demand at the pressure required at the pump discharge and provides the design flow of the fire pumps.

An analysis confirms that the as-built fire pumps provide the flow demand for the largest sprinkler or deluge system plus an additional 500 gpm for fire hoses assuming failure of the largest fire pump or loss of off-site power.

In accordance with FSAR Table 14.2-22, a preoperational test demonstrates that each fire pump delivers the design flow to the FPS.

03.07.03 FSAR Section 9.5.1 discusses that (a) safe-shutdown can be achieved assuming that all equipment in any one fire area (except for the MCR and containment) is rendered inoperable by fire and that reentry into the fire area for repairs and operator actions is not possible, (b) that smoke, hot gases, or fire suppressant cannot migrate from the affected fire area into other fire areas to the extent that they could adversely affect safe shutdown capabilities, including operator actions, and (c) an independent alternative shutdown capability that is physically and electrically independent of the MCR exists.

A safe shutdown analysis of the as-built plant will be performed, including a post-FSSD circuit analysis performed in accordance with RG 1.189 and NEI 00-01 for all possible fire-induced failures that could affect the safe shutdown success path, including multiple spurious actuations.

The safe shutdown analysis will verify that

  • safe shutdown can be achieved assuming that all equipment in any one fire area (except for the MCR and containment) is rendered inoperable by fire and that reentry into the fire area for repairs and operator actions is not possible.
  • smoke, hot gases, or fire suppressant cannot migrate from the affected fire area into other fire areas to the extent that they could adversely affect safe shutdown capabilities, including operator actions.
  • I&C equipment rooms within the RXB used as the alternative shutdown capability are physically and electrically independent of the MCR.

03.07.04 FSAR Appendix 9A, Fire Hazards Analysis, discusses the methodology and presents the FHA for each fire area. The FHA must reflect the as-built configuration of the plant. The FHA is an analysis of the fire hazards, including combustible loading and ignition sources, and analysis of the fire protection features required to mitigate each postulated fire.

An FHA of the as-built plant will be performed in accordance with RG 1.189, as described in FSAR Appendix 9A. The FHA will verify (1) combustible loads and ignition sources are accounted for, and (2) fire protection features are suitable for the hazards for which they are intended.

03.11.01 FSAR Section 9.5.1, Fire Protection Program, discusses that fire and smoke barriers separate: (1) safety-related systems from any potential fires in nonsafety-related areas that could affect the ability of safety-related systems to perform their safety-related function, (2) redundant divisions or trains of safety-related systems from each other to prevent damage that could adversely affect a safe shutdown function from a single fire, (3) equipment within a single safety-related electrical division that present a fire hazard to equipment in another safety-related division, and (4) electrical circuits (safety-related and nonsafety-related) whose fire-induced failure could cause a spurious actuation that could adversely affect a safe shutdown function.

An ITAAC inspection is performed to verify that the following RXB as-built fire barriers and smoke barriers are installed in accordance with the FHA and are qualified for the fire rating specified in the FHA:

  • fire-rated doors
  • smoke barriers
  • fire-rated walls, floors, and ceilings The objective of the inspection is to verify that the fire and smoke barriers meet the design requirements, meet the location requirements, and are qualified for their intended use based upon visual inspection and review of the as-built drawings and qualification documentation.

03.11.02 FSAR Section 3.4.1, Internal Flood Protection for Onsite Equipment Failures, discusses the features used to mitigate the consequences of internal flooding, which include structural enclosures, barriers, curbs, sills, and watertight seals.

An ITAAC inspection is performed to verify that the following RXB as-built internal flooding barriers are installed in accordance with the internal flooding analysis report and are qualified as specified in the internal flooding analysis report:

  • flood resistant doors
  • curbs and sills
  • walls
  • NEMA enclosures The objective of the inspection is to verify that the flooding barriers meet the design requirements, meet the location requirements, and are qualified for their intended use based upon visual inspection and review of the as-built drawings and qualification documentation.

03.11.04 FSAR Section 12.3, Radiation Protection Design Features, provides the design bases for radiation shielding, including type, form and material properties utilized in specific locations. Radiation shielding is provided to meet the radiation zone and access requirements for normal operation and post-accident conditions, and to demonstrate compliance with 10 CFR 50.49, GDC 4, PDC 19, GDC 61, 10 CFR 50.34(f)(2)(vii), and other relevant requirements. Compartment walls, ceilings, and floors, or other barriers provide shielding.

An ITAAC inspection is performed of the RXB radiation barriers to verify wall materials and thicknesses.

The required thicknesses are specified in FSAR Table 12.3-6. Attenuation capabilities are determined based on wall materials and thicknesses, and an analysis and report will conclude that attenuation capabilities are greater than or equal to the approved design.

03.11.05 FSAR Section 12.3.2 provides the design bases for radiation shielding. Radiation shielding is provided to meet the radiation zone requirements for normal operation and control room access requirements for post-accident conditions. Radiation attenuating doors must meet or exceed the radiation attenuation capability of the wall within which they are installed.

An ITAAC inspection is performed to verify that the RXB radiation attenuating doors are installed in their design location and have a radiation attenuation capability that meets or exceeds that of the wall within which they are installed in accordance with the approved door schedule design.

03.11.06 FSAR Section 3.8.4 and Appendix 3B provide descriptive information, including plans and sections of each Seismic Category I structure, to establish that there is sufficient information to define the primary structural aspects and elements relied upon for the structure to perform the intended safety functions. Critical dimensions are identified in FSAR Appendix 3B. The RXB and its design basis loads are discussed in FSAR Section 3.8.4. Critical sections are the subcomponents of individual Seismic Category I structures (i.e., shear walls, floor slabs and roofs, structure-to-structure connections) that are analytically representative of an essentially complete design. Design basis load combinations are shown in FSAR Tables 3.8.4-1 and 3.8.4-2.

A reconciliation analysis of the as-built RXB is performed to ensure the RXB maintains its structural integrity in accordance with the approved design under the actual design basis loads, and the in-structure responses for the RXB are enveloped by those in the approved design. The design summary report provides criteria for the reconciliation between design and as-built conditions, as described in FSAR Section 3.8.4.

03.11.07 FSAR Section 3.2.1, Seismic Classification, discusses that per RG 1.29, some SSC that perform no safety-related functions could, if they failed under seismic loading, prevent or reduce the functioning of Seismic Category I SSC.

An ITAAC inspection and analysis is performed to verify that the as-built non-Seismic Category I SSC where there is a potential for adverse interaction with the RXB or a Seismic Category I SSC in the RXB will not impair the ability of Seismic Category I SSC to perform their safety functions as demonstrated by one or more of the following criteria:

i. Seismic Category I SSC are isolated from non-Seismic Category I SSC so that interaction does not occur.

ii. Seismic Category I SSC are analyzed to confirm that the ability to perform their safety functions is not impaired as a result of impact from non-Seismic Category I SSC.

A non-Seismic Category I restraint system designed to Seismic Category I requirements is used to ensure that no interaction occurs between Seismic Category I SSC and non-Seismic Category I SSC.

03.12.02 FSAR Section 12.3 provides the design bases for radiation shielding. Radiation shielding is provided to meet the radiation zone requirements for normal operation and post-accident conditions, and to demonstrate conformance to RG 4.21 and RG 8.8. Radiation attenuating doors must meet or exceed the radiation attenuation capability of the wall within which they are installed.

An ITAAC inspection is performed to verify that the RWB radiation attenuating doors are installed in their design location and have a radiation attenuation capability that meets or exceeds that of the wall within which they are installed in accordance with the approved door schedule design.

03.12.03 The RW-IIa RWB and its design basis loads are discussed in FSAR Section 3.8.4. Design basis loads for RW-IIa structures as listed in RG 1.143.

A reconciliation analysis of the as-built RW-IIa RWB is performed to ensure that deviations between the drawings used for construction and the as-built RW-IIa RWB are reconciled and the RW-IIa RWB maintains its structural integrity under the design basis loads in accordance with the approved design under the actual design basis loads, and the in-structure responses for the RWB are enveloped by those in the approved design.

03.13.01 FSAR Section 9.5.1, Fire Protection Program, discusses that fire and smoke barriers separate: (1) safety-related systems from any potential fires in nonsafety-related areas that could affect the ability of safety-related systems to perform their safety-related function., (2) redundant divisions or trains of safety-related systems from each other to prevent damage that could adversely affect a safe shutdown function from a single fire., (3) equipment within a single safety-related electrical division that present a fire hazard to equipment in another safety-related division, and (4) electrical circuits (safety-related and nonsafety-related) whose fire-induced failure could cause a spurious actuation that could adversely affect a safe shutdown function.

An ITAAC inspection is performed to verify that the following CRB as-built fire barriers and smoke barriers are installed in accordance with the FHA and are qualified for the fire rating specified in the FHA:

  • fire-rated doors
  • smoke barriers The objective of the inspection is to verify that the fire and smoke barriers meet the design requirements, meet the location requirements, and are qualified for their intended use based upon visual inspection and review of the as-built drawings and qualification documentation.

03.13.02 FSAR Section 3.4.1, Internal Flood Protection for Onsite Equipment Failures, discusses the features used to mitigate the consequences of internal flooding, which include structural enclosures, barriers, and watertight seals.

An ITAAC inspection is performed to verify that the following CRB as-built internal flooding barriers are installed in accordance with the internal flooding analysis report and are qualified as specified in the internal flooding analysis report:

  • flood resistant doors
  • walls
  • NEMA enclosures The objective of the inspection is to verify that the flooding barriers meet the design requirements, meet the location requirements, and are qualified for their intended use based upon visual inspection and review of the as-built drawings and qualification documentation.

03.13.03 FSAR Section 2.4.2, Floods, discusses that the maximum flood elevation (including wind-induced wave run-up) is one foot below baseline plant elevation. FSAR Section 3.4.2.1, Probable Maximum Flood, states that the design basis flood level (including wave action) is one foot below the baseline top of concrete elevation at the ground level floor.

An ITAAC inspection is performed to verify that the CRB as-built floor elevation at ground entrances is located above the maximum external flood elevation to protect the CRB from external flooding. The inspection will compare the maximum external flood elevation against the CRB as-built design drawings to verify that the floor elevation at ground entrances is a minimum of one foot above the maximum external flood elevation.

03.13.04 FSAR Section 3.8.4 and FSAR Appendix 3B provide descriptive information, including plans and sections of each Seismic Category I structure, to establish that there is sufficient information to define the primary structural aspects and elements relied upon for the structure to perform the intended safety functions.

Critical dimensions are identified in Appendix 3B. The CRB design basis loads are discussed in FSAR Section 3.8.4. Critical sections are the subcomponents of individual Seismic Category I structures (i.e.,

shear walls, floor slabs and roofs, structure-to-structure connections) that are analytically representative of an essentially complete design. Design basis loads load combinations are shown in FSAR Tables 3.8.4-1 and 3.8.4-2.

A reconciliation analysis of the as-built Seismic Category I areas of the CRB is performed to ensure the CRB maintains its structural integrity in accordance with the approved design under the actual design basis loads, and the in-structure responses for the CRB are enveloped by those in the approved design.

The design summary report provides criteria for the reconciliation between design and as-built conditions, as described in FSAR Section 3.8.4.

03.13.05 FSAR Section 3.2.1, Seismic Classification, discusses that per RG 1.29, some SSC that perform no safety-related functions could, if they failed under seismic loading, prevent or reduce the functioning of Seismic Category I SSC.

An ITAAC inspection and analysis is performed to verify that the as-built non-Seismic Category I SSC located where a potential for adverse interaction with a Seismic Category I SSC exists will not impair the ability of Seismic Category I SSC to perform their safety functions as demonstrated by one or more of the following criteria:

i. The collapse of the non-Seismic Category I structure will not cause the non-Seismic Category I structure to strike a Seismic Category I SSC.

ii. The collapse of the non-Category I structure will not impair the integrity of Seismic Category I SSC, nor result in incapacitating injury to control room occupants.

iii. The non-Category I structure will be analyzed and designed to prevent its failure under SSE conditions.
