Introduction This document represents the Final Safety Analysis Report (FSAR) required under 10 CFR 52.47(a) to be provided as part of an application for a standard design certification under 10 CFR 52, Subpart B and will be referred to as such throughout. It describes the NuScale Power, LLC design, including (1) the design bases and limits on its operation; (2) a safety analysis of the structures, systems, and components and of the facility as a whole; and (3) the information prescribed in 10 CFR 52.47(a) that is relevant to the NuScale design.

A NuScale Power Module (NPM) shown in Figure 1.2-6 and Figure 1.2-7, is a collection of systems, sub-systems, and components that together constitute a modularized, movable, nuclear steam supply system (NSSS). The NPM is composed of a reactor core, a pressurizer, and two steam generators integrated within a reactor pressure vessel (RPV) and housed in a compact steel containment vessel.

The NuScale advanced small modular reactor plant design is scalable, such that from one (1) to twelve (12) NPMs operate within a single Reactor Building. The information provided in this FSAR includes the design of an individual NPM, as well as plant design and interfaces for a 12 NPM facility. In general, chapters describe a single module. Multi-module information is only noted where warranted (e.g., shared systems or analyses such as seismic).

The NuScale design features:

• No AC or DC power required for safe shutdown and cooling

• Compact helical coil steam generators with reactor pressure on the outside of the tubes

• High-strength steel containment immersed in a pool of water

• Sub-atmospheric containment pressure during normal operation

• Small core with a correspondingly small source term

• Comprehensive digital instrumentation and controls (I&C) monitoring and control Important features of a multi-unit plant include:

• a scalable plant design, which allows for incremental plant capacity growth.

• a compact nuclear island.

• the ability to operate in "island mode".

1 Plant Location The NuScale Power Plant is designed to be located on a site having site characteristics (e.g.,

seismology, hydrology, meteorology, geology, and other site-related characteristics) bounded by the parameters described in Chapter 2, Site Characteristics.

Item 1.1-1: A COL applicant that references the NuScale Power Plant design certification will identify the site-specific plant location.

2 1.1-1 Revision 1

The NuScale containment vessel (CNV) is a supported, cylindrical vessel-type containment that is designed to withstand limiting high-pressure transients. The containment vessel (CNV) is an American Society of Mechanical Engineers (ASME) Boiler Pressure Vessel Code (BPVC) Class MC (steel) containment that is designed, analyzed, fabricated, inspected, tested and stamped as an ASME BPVC Class 1 pressure vessel. The CNV internal pressure is maintained at a vacuum during normal operations and as such insulation materials are not required between the reactor vessel and the CNV. The containment vessels are mounted to the Reactor Building module compartment walls and at the bottom within the Reactor Building pool.

3 Reactor Type The NuScale NSSS is a passive NuScale-designed small modular pressurized water reactor.

This design is comprised of an integral power module consisting of a reactor core, two steam generator tube bundles, and a pressurizer contained within a single reactor vessel, along with the containment vessel that immediately surrounds the reactor vessel. This design eliminates the need for external piping to connect the steam generators and pressurizer to the RPV. Natural circulation provides reactor coolant system flow, thereby eliminating the need for reactor coolant pumps.

4 Power Output A NuScale Power Plant consists of from one to12 NPMs. Each NPM is rated at 160 MWt (1,920 MWt, total), with approximately 50 MWe (600 MWe total) output. Electrical output is dependent on environmental conditions. When considering house loads, the total net output is approximately 570 MWe for a 12 NPM facility. Design power assumes an additional 2% to account for measurement uncertainty.

5 Schedule Item 1.1-2: A COL applicant that references the NuScale Power Plant design certification will provide the schedules for completion of construction and commercial operation of each power module.

6 Format and Content 6.1 Regulatory Guide 1.206 The format and content of this FSAR generally follow the format and content guidelines of Regulatory Guide 1.206. However, where applicable, Sections may be skipped or additional sections inserted. In addition, this FSAR includes Chapter 20, Mitigation of Beyond-Design-Basis Events and Chapter 21, Multi-Module Design Considerations, which are not included in Regulatory Guide (RG) 1.206.

6.2 Standard Review Plan - NuScale Design Specific Review Standard A NuScale design specific review standard (DSRS) has been developed by the NRC as a supplement to NUREG-0800, Standard Review Plan for the Review of Safety Analysis 2 1.1-2 Revision 1

NuScale design. A detailed evaluation of conformance with the NuScale DSRS and the SRP is provided in Section 1.9.

6.3 Text, Tables, and Figures Tables and figures are typically identified by the "X.Y" section in which they appear and are numbered sequentially. For example, Table 1.1-1 and Figure 1.1-1 would be the first table and figure appearing in Section 1.1. Figures consist of diagrams, plots, pictures, graphs, or other illustrations. Tables and figures are located at the end of the applicable "X.Y" section immediately following the text. The exception to this is for large "X.Y.Z" sections, in which the tables and figures are numbered sequentially in that section. For example, Table 3.9.3-1 and Figure 3.9.3-1 would be the first table and figure appearing in Section 3.9.3. Again, the tables and figures are located at the end of the applicable section intermediately following the text.

6.4 Page Numbering Section pages are numbered sequentially and are typically identified by the "X.Y" section followed by a sequential number. The exception to this convention is for chapter appendices, which are numbered by the chapter number and appendix letter followed by a sequential number. For example, 3A-1 is the first page of Appendix A to Chapter 3.

6.5 Proprietary Information This FSAR does not contain proprietary or safeguards information. Some portions of this FSAR are classified as sensitive and withheld from public disclosure pursuant to 10 CFR 2.390 and Regulatory Issue Summary (RIS) 2005-26. Such material is clearly marked and provided with the non-public version of the FSAR. A separate public version of the FSAR is provided that removes the withheld material.

Each COL Applicant will develop a Final Safety Analysis Report (FSAR) that incorporates by reference the NuScale FSAR. The NuScale FSAR includes COL items that identify where site-specific information must be provided. However, in some instances, representative information is necessary to provide context for interface requirements as specified in 10 CFR 52.47(a)(24) and 10 CFR 52.47(a)(25).

A NuScale Power Module (NPM) shown in Figure 1.2-6, is a collection of systems, sub-systems, and components that make up a modularized, movable, nuclear steam supply system (NSSS). Each NPM is comprised of a reactor core, a pressurizer, and two steam generators (SGs) integrated within a reactor pressure vessel (RPV) and housed in a compact steel containment vessel (CNV). The NuScale Power Plant is designed for 1 to 12 NPMs with the associated primary and secondary systems and components necessary to produce power and maintain the facility.

6) ((Site Cooling Water System (SCWS): provides cooling water to plant auxiliary systems.))

Additional details of the SCWS are provided in Section 1.2.1.6. 1.1 Facility Description Process Overview The reactor core is located in a core support assembly, which is seated in the lower RPV assembly. A central hot leg riser is connected to the top of the core support assembly. The reactor core transfers heat into the reactor coolant and the heated reactor coolant flows upward through the core and lower and upper riser assemblies. The heated coolant exits the upper riser assembly and is redirected downwards into the SG region between the vessel wall and the upper riser assembly. As the reactor coolant transfers heat to the SGs, it cools and becomes denser, which drives the natural circulation flow. The coolant returns to the bottom of the vessel through the downcomer and back into the reactor core, where the cycle begins again (Figure 1.2-7). On the secondary side, preheated feedwater is pumped into the tube side of the SGs where it boils. As the steam flows upward in the tubes, it is continually heated to produce superheated steam before exiting the top of the SGs. The superheated steam is directed to a dedicated steam turbine. A generator, driven by the turbine, creates electric power that is delivered to the utility grid through a step-up transformer. A turbine bypass line provides up to 100% of the rated main steam flow directly from the associated steam generators to the main condenser in a controlled manner to remove heat from the reactor following a load reduction or loss of electrical load. Steam that exits or bypasses the turbine is directed to the condenser. A shared circulating water loop removes heat and condenses the steam for up to 6 condensers. The condensate is pumped through condensate polishing equipment to the inlet of the variable speed feedwater pumps. A small amount of steam is extracted from turbine stages to preheat the feedwater and increase plant efficiency. Feedwater regulating valves control feed flow into the SGs. ((Heat from the circulating water loop from up to 6 condensers is rejected to atmosphere by a set of evaporative mechanical-draft cooling towers. Two sets of cooling towers are provided for 12 NPMs.)) 1.1.1 Principal Design Criteria The design provides a simple, safe reactor and provides the following:

• reliable, passive safety systems that are simple in design and operation, and are not reliant on electrical power to fulfill their safety functions 2 1.2-3 Revision 1
• the absence of RPV or containment penetrations below the top of the reactor core
• modularization to enable in-shop fabrication of reactor and containment components 1.1.2 Operating Characteristics The NPM is designed to operate up to full power conditions using natural circulation as the means of providing reactor coolant flow, eliminating the need for reactor coolant pumps.

The NPMs are partially immersed in a reactor pool and protected by passive safety systems. Each NPM has a dedicated emergency core cooling system (ECCS) and decay heat removal system (DHRS). Important features of the NPM include the following:

• a small, modular design
• an integral pressurized water reactor (PWR) NSSS that combines the reactor core, SGs, and pressurizer within the RPV, eliminating the need for external piping to connect the SGs and pressurizer to the RPV
• natural circulation provides the driving force for reactor coolant flow, eliminating the need for reactor coolant pumps
• an RPV housed in a steel containment partially immersed in water, providing an effective passive heat sink for long-term decay heat removal
• a steel containment operated at a vacuum, eliminating the need for insulation on the RPV
• passive safety systems that are not reliant on electrical power Table 1.2-1 presents the overall characteristics of the NuScale Power Plant.

The NPM is designed to perform normal power maneuvers. Electric power can be adjusted with turbine bypass to the condenser. In addition, core power maneuvering can be accomplished with control rods, soluble boron concentration changes, or a combination of control rods and soluble boron as described in Sections 4.2 and 4.3. Nuclear Steam Supply System The NSSS consists of a reactor core, two helical-coil SGs, and a pressurizer integrated within the RPV. The RPV is enclosed in an approximately cylindrical CNV that sits in the reactor pool. The reactor core is located below the helical-coil SGs inside the RPV. Using natural circulation, the primary reactor coolant flow path is upward through the central hot leg riser, and then downward around the outside of the SG tubes with return flow to the bottom of the core via an annular 2 1.2-4 Revision 1

fluid progresses up through the inside of the SG tubes, it is heated, boiled, and superheated to produce high pressure steam for the turbine generator unit. Reactor Core The core configuration for the NPM consists of 37 fuel assemblies and 16 control rod assemblies (CRAs). The CRAs are organized into two banks: a regulating bank and a shutdown bank. The regulating bank, consisting of four CRAs symmetrically located in the core, is used during normal plant operation to control reactivity. The shutdown bank (12 CRAs in three groups) is used during normal shutdown. All 16 CRAs are inserted for scram events. The fuel assembly design is similar to a standard 17x17 PWR fuel assembly with 24 guide tube locations for control rods and a central instrument tube. The only significant differences are the fuel assembly is nominally half the height of a standard fuel assembly and is supported by five spacer grids. The fuel is uranium dioxide, UO2, with gadolinium oxide, Gd2O3, as a burnable absorber homogeneously mixed within the fuel in select rod locations. The U-235 enrichment is less than 4.95 percent. A list of fuel design parameters is presented in Table 4.2-1. Pressurizer The pressurizer provides the primary means for controlling reactor coolant system (RCS) pressure. It is designed to maintain a stable reactor coolant pressure during operation. Reactor coolant pressure is increased by applying power to a pair of heater bundles installed above the pressurizer baffle plate. Pressure in the RCS is reduced using spray provided by the chemical and volume control system (CVCS). Steam Generator Each NPM uses two once-through, helical-coil SGs for steam production. The SGs are located in the annular space between the hot leg riser and the RPV inside diameter wall. The SG consists of tubes connected to feed and steam plenums with tube sheets. Preheated feedwater enters the lower feed plenum through nozzles on the RPV. As feedwater flows through the interior of the SG tubes, heat is transfered across the SG tube wall from the reactor coolant to the feedwater. The feedwater changes phase and exits the SG as superheated steam. Reactor Pressure Vessel The RPV consists of an approximately cylindrical steel vessel with an inside diameter of approximately 9 ft and an overall height of approximately 58 ft that is designed for an operating pressure of approximately 1,850 psia. The upper and lower heads are torispherical, and the lower portion of the vessel has a flange to provide access for refueling. 2 1.2-5 Revision 1

upper and lower sections are flanged together using bolts. The torispherical RPV head supports the control rod drive mechanisms (CRDMs) and includes penetrations ranging from 2 to 8 diameter for pressurizer spray, reactor vent valves, reactor safety valves, reactor high point degasification instrumentation and controls (I&C) instrument channels, and the CRDM nozzles. The RPV upper section is cylindrical, approximately 9 ft in diameter with slightly thicker sections at the feedwater inlet and steam outlet areas. The upper section includes penetrations ranging from 2.25 to 25 diameter for main steam piping nozzles and main steam access ports, pressurizer heaters, feedwater piping nozzles and feedwater access ports, reactor recirculation valves, CVCS, and pressure instrumentation. The RPV lower section is cylindrical, approximately 9 ft in diameter and includes a torispherical lower head that is welded in place. There are no penetrations in the lower section of the RPV. A steel pressurizer baffle plate integral with the RPV provides a barrier between the saturated water in the pressurizer and the RCS. The pressurizer baffle plate is integrated with the upper steam plenums, has flow holes to allow surges of water into and out of the pressurizer, and to act as a thermal barrier. Containment Vessel The CNV is a cylindrical, steel pressure vessel housing the RPV, CRDMs, and associated NSSS piping and components. The CNV has an overall height of approximately 76 ft and an outside diameter of approximately 15 ft and consists of an upper CNV section with a welded torispherical top head and a lower CNV section with a welded head. The upper and lower CNV sections are flanged together using bolts. The flange connection permits the CNV to be separated to provide access to the RPV for refueling and maintenance. The safety functions of the CNV are to contain the release of radioactive material following postulated accidents and to provide heat rejection to the reactor pool following ECCS actuation. The CNV also provides support for the RPV. Manways provide access to components located inside the CNV. Penetrations on the CNV upper head are provided for process piping, electrical power, and instrumentation. The CNV is supported laterally by support lugs located slightly below the steam plenum elevation and by the support skirt attached to the CNV lower head. The support skirt also provides vertical support for the CNV. Internal to the CNV, the RPV is laterally and vertically supported by four support plates located slightly below the steam plenum elevation and is laterally supported at the center of the lower RPV head. 2 1.2-6 Revision 1

environment of the reactor pool as well as the internal pressure and temperature of a design-basis accident. The CNV is maintained at a vacuum under normal operating conditions. The benefits of maintaining a vacuum in the CNV include:

• minimizes moisture content that could impact the reliability and contribute to corrosion of components within the CNV
• facilitates detection of leakage from the reactor coolant pressure boundary
• eliminates convective heat transfer and therefore, the need for RPV insulation, which reduces potential debris generated in the CNV
• limits the initial amount of oxygen in containment (severe accident combustible gas consideration)

Following an actuation of the ECCS, steam is vented from the RPV through the reactor vent valves. This results in an initial spike in containment pressure and temperature. Steam in contact with the inside surface of the CNV is passively cooled and condensed by conduction and convection to the reactor pool water. This passive process rapidly reduces containment pressure and temperature and maintains containment pressure and temperature at less than design conditions indefinitely. 1.1.3 Safety Considerations NuScale has achieved an improvement in safety over existing plants through simplicity of design, reliance on passive safety systems, and small fuel inventory. The integral design of the NPM eliminates external coolant loop piping, which eliminates large-break LOCA scenarios. The availability of passive safety systems for decay heat removal, emergency core cooling, and control room habitability eliminates the need for external power under accident conditions. With these passive safety systems, small-break LOCAs do not challenge the safety of the plant. The result is a design with a core damage frequency that is lower than the current light water reactor fleet. The reactor core has a small radioactive source term as compared to a conventional 1,000 MWe nuclear reactor. Based on the smaller fuel inventory, the amount of radioactive material available for release during a postulated accident is reduced. Table 1.2-2 provides a listing of some of the features of the NPM. 1.2 Engineered Safety Features and Emergency Systems 1.2.1 Engineered Safety Feature Materials Details are provided in Section 6.1 related to the selection and fabrication methods for metallic and organic materials used in ESF components to ensure compatibility with fluids that the component may be exposed to during normal, accident, maintenance, and testing conditions. 2 1.2-7 Revision 1

The containment is an integral part of the NPM and provides primary containment for the RCS. Section 6.2 provides further information for the containment system. 1.2.3 Emergency Core Cooling System The ECCS provides a passive means of decay heat removal in the event of a LOCA. The ECCS consists of three independent reactor vent valves and two independent reactor recirculation valves (Figure 1.2-9). All five valves are closed during normal operation. During ECCS operation, the reactor vent valves vent steam from the RPV into the CNV where the steam condenses and collects in the bottom of the containment. The reactor recirculation valves allow water to reenter the RPV and be circulated through the core. When reactor coolant temperature is reduced to below the boiling point, core cooling continues via conduction directly into the reactor pool. The cooling function of the ECCS is entirely passive, with heat being conducted through the CNV wall to the reactor pool. Section 6.3 provides design and operational information for the ECCS. 1.2.4 Control Room Habitability System The control room habitability system (CRHS) ensures that plant operators are adequately protected against the effects of accidental releases of toxic or radioactive gases. The CRHS is a passive system that provides clean, compressed, breathable air to the MCR in the event of a radioactive release or when AC power is not available. Areas served by the CRHS are maintained at positive pressure relative to adjacent areas. Compressed breathable air storage capacity can provide clean air to the MCR spaces for at least 72 hours following an initiating event. Section 6.4 provides design and operational information for the CRHS. 1.2.5 Fission Product Removal and Control Systems The only fission product removal and control system credited in the design is the CNV in conjunction with the containment isolation system. Fission product control is inherent in the design of the NPM, wherein the CNV atmosphere is depleted through the passive process of aerosol deposition. Section 6.5 provides information for this ESF. 1.2.6 In-service Inspection of Class 2 and 3 Components The in-service inspection program includes the pre-service examinations and the periodic inservice inspections and tests necessary to ensure that safety-related and risk-significant systems, structures, and components are capable of fulfilling their intended safety functions. Section 6.6 provides detailed information for the in-service inspection program. 2 1.2-8 Revision 1

The I&C architectural design philosophy incorporates clear interconnection interfaces, separation between safety and non-safety systems, and simplification of system functions. The I&C architecture primarily consists of the following systems, which are described in Section 7.0:

• module protection system (MPS) provides information from safety-related sensors monitoring temperature, flow, neutron flux, and pressure data on the NSSS.
• neutron monitoring system measures neutron flux as an indication of core power and provides safety inputs to the MPS.
• module control system (MCS) is a distributed control system that allows monitoring and control of module-specific plant components.
• plant control system supplies non-safety inputs to the human system interfaces in the MCR, the remote shutdown station, and other locations where necessary.
• fixed area radiation monitoring system continuously monitors in-plant radiation and airborne radioactivity levels.
• safety display and indication system provides visual display and indication in the MCR from the MPS and plant protection system.
• plant protection system monitors and controls systems that are common to all NPMs and are not specific to an individual NPM.
• health physics network provides the permanently installed communications infrastructure necessary to support a licensee-implemented radiation protection program.
• in-core instrumentation system monitors various parameters within the reactor core and RCS and sends the parameter values to the MCS for display and evaluation.

Under normal operating conditions the AC electrical power distribution system supplies continuous power to equipment required for startup, normal operation, and shutdown of the plant. The NuScale Power Plant does not require onsite or offsite AC electrical power to cope with design-basis events. Safety systems are not reliant on AC or DC electrical power for actuation. The power systems within the plant are described below:

• The 13.8 KV and switchyard system provides power from the turbine generators and the auxiliary AC power source to the 13.8 kV AC buses and connects the onsite AC system to the switchyard.
• Medium voltage AC electrical distribution system provides power at 4,160V AC to buses servicing medium voltage loads.
• Low voltage AC electrical distribution system provides power at 120V AC and 480V AC to buses servicing low voltage loads.
• Highly reliable DC power system provides a failure-tolerant source of 125V DC power to plant loads including emergency lighting, MPS, PPS, and post-accident monitoring loads.

2 1.2-9 Revision 1

• Backup power is provided for onsite AC power. The backup diesel generators provide power at the 480VAC level and the auxiliary AC power source provides power at the 13.8kVAC level.

1.4 Power Conversion System The power conversion systems associated with an NPM consist of a main steam system, a turbine generator set, a standard condenser and cooling tower arrangement, and a condensate and feedwater system as shown in Figure 1.2-3. With multiple NPMs per plant, individual NPMs can be placed into service incrementally to meet construction schedules and grid demand as permitted by the site license. NPMs can also be taken off-line individually for refueling outages and maintenance. 1.5 Fuel Handling and Storage Systems The fuel handling and reactor maintenance areas are located in the west end of the RXB and include space for the SFP, refueling pool, and dry dock. The pools are shown in Figure 1.2-16. 1.6 Plant Cooling Water Systems The plant cooling water systems include several systems that are important to supporting plant operation. These systems include the following:

• The reactor component cooling water system (RCCWS) is a nonsafety-related, closed-loop cooling system that transfers heat from various plant components to the site cooling water system. The RCCWS provides cooling to the CRDMs, the non-regenerative heat exchangers for each CVCS, and the primary sampling system coolers. (Section 9.2.2)
• The reactor pool cooling system and the spent fuel pool cooling system are nonsafety-related, closed-loop systems that transfer heat from the associated pool to the site cooling water system. (Section 9.1.3)
• The circulating water system is an open-loop system that provides a continuous supply of cooling water to the plant turbine condensers. Circulating water pumps draw water from a common basin to provide cooling water flow for up to six condensers in one TGB. Heated circulating water from the outlet of the condensers flows to a set of mechanical-draft cooling towers where excess heat is removed as the water gravity flows back to the common basin. (Section 10.4.5)
• The site cooling water system is an open-loop system that provides a continuous supply of cooling water to the chilled water system, the balance of plant component cooling water system, the spent fuel pool cooling system, the reactor pool cooling system, the RCCWS, and the condenser air removal system. Site cooling water pumps draw water from a common basin to provide cooling water flow to the systems serviced. Heated site cooling water from the outlet of the 2 1.2-10 Revision 1

to the common basin. (Section 9.2.7) 1.7 Radioactive Waste Management System The radioactive waste management system is discussed in detail in Chapter 11. Liquid, gaseous, and solid radioactive waste management systems are discussed in detail in Sections 11.2, 11.3, and 11.4, respectively. Process effluent radiation monitoring and sampling systems are discussed in Section 11.5. 2 General Arrangement of Major Structures and Equipment Figure 1.2-2 presents the layout of a NuScale Power Plant. This figure includes an administration and training building and a warehouse that are outside the scope of the FSAR and not discussed further. 2.1 Reactor Building As shown in Figure 1.2-2, the RXB is approximately central to the site. See Figure 1.2-5 and Figure 1.2-10 through Figure 1.2-20 for RXB drawings. Dimensions provided in Figure 1.2-5 are nominal or approximate values for illustrative purposes. The RXB houses the NPMs and systems and components required for plant operation and shutdown. The RXB is primarily a rectangular configuration that is approximately 350 ft long and 150 ft wide, and extends approximately 81 ft above nominal plant grade level. The bottom of the RXB foundation is 86 ft below grade except for the areas under the elevator pit and the refueling pool, which are approximately 92 ft below grade. The RXB is a Seismic Category I, reinforced concrete structure with design considerations for the effects of aircraft impact, environmental conditions, postulated design basis accidents (internal and external), and design basis threats. The RXB also provides radiation protection to plant operations and maintenance personnel. Each NPM is located in the common reactor pool in its own three-walled bay with the open wall towards the center of the pool. The bays are arranged into two rows with six bays per row along the north and south walls of the reactor pool at the east end of the pool. A central channel is provided between the bays to allow for movement of the NPMs between the bays and the refueling pool. The bays are approximately 20 ft wide by 20 ft long by 98 ft deep with a normal reactor pool water depth of approximately 69 ft (this correlates to an elevation of approximately 94'). Each bay has a concrete bioshield to reduce radiation levels in the RXB and to prevent deposition of foreign materials onto an NPM. The bioshield consists of a two foot thick horizontal slab comprised of reinforced concrete and polyurethane with a stainless steel surface and steel vertical faceplate that extends into the pool. The horizontal slab is bolted to the top of the bay. The bioshields are designed to be removed to access the NPM. To accommodate the removed bioshield, each bioshield is designed to have another bioshield stacked on top of it to allow for NPM movement during refueling. The NPM, reactor pool, and SFP are below grade. The surface of the reactor pool water is approximately 6 feet below grade. Also located below grade are most primary 2 1.2-11 Revision 1

Pipe fittings and electrical connections are provided above the reactor pool water level to permit manual connection and disconnection during NPM installation, refueling outages, and during replacement or removal of NPMs. There is no safety-related equipment on the 125'-0 elevation. With the exception of demineralized water isolation valves, which are located on the 50'-0" elevation, there is no safety-related equipment below the 75'-0 elevation. Table 3.2-1, Classification of Structures, Systems, and Components, provides the location and classification of systems, structures, and components. 2.1.1 Fuel Handling and Reactor Maintenance Areas The fuel handling and reactor maintenance areas are located in the west end of the RXB and include space for the SFP, refueling pool, and dry dock. The pools are shown in Figure 1.2-16. The operating areas at the west end, 100'-0" elevation of the RXB provide space for the operation of fuel handling equipment and accessing the upper portion of an NPM while the reactor core is being refueled. The refueling pool is connected directly to the reactor pool accommodating transport of an NPM through the pool water using the Reactor Building crane (RBC). A weir between the refueling pool and SFP provides access for fuel assembly transport under water during the refueling process. The fuel handling and maintenance areas are designed to provide radiation protection for plant operations and maintenance personnel who are working in those areas. The area west of the SFP contains a fuel receiving area and a jib crane for loading new fuel assemblies into the new fuel elevator. The area has pallet jack access to aid in new fuel receiving activities. Upon receipt, new fuel assemblies are inspected and temporarily stored in racks in the SFP before being placed in a reactor core. The SFP provides storage space for the accumulated spent fuel assemblies prior to removal for dry storage and for temporary short-term storage for new fuel assemblies. Spent fuel assemblies removed from the reactor core are placed in spent fuel storage racks in the SFP. The refueling pool contains the bolting tools to disassemble and reassemble the NPM during refueling. The reactor core remains in the lower head of the RPV while in the refueling pool for refueling and fuel management. A fuel handling machine moves new and used fuel through the weir between the refueling pool and SFP. The dry dock area contains the module inspection rack and is separated from the refueling pool by a gate. With the gate closed, the dry dock water level can be lowered and maintenance activities on the upper NPM can be completed. Necessary inspection and testing equipment for the NPM are moved to this area during refueling. 2 1.2-12 Revision 1

preparing them for assembly. Additionally, it provides access for shipment of used NPMs off-site. 2.1.2 Refueling Operations Refueling operations for an individual NPM is independent of the operating status of the remaining NPMs. During refueling, an NPM is moved from its operating bay in the reactor pool to the refueling pool using the RBC. The RBC lifts the NPM off its supports within the reactor bay and moves it to the open channel in the center of the reactor pool, which serves as a pathway to transport the NPM to the refueling area. In the refueling area, the NPM is set into the containment flange tool where the CNV flange is unbolted. The crane lifts the NPM, separating the lower CNV from the upper CNV with RPV still attached and intact. Next, the crane moves the upper CNV and RPV to the reactor vessel flange tool where the RPV flange is unbolted. The crane again lifts the NPM, this time separating the upper and lower RPV, leaving the lower RPV including the reactor core, in the reactor vessel flange tool. Finally, the crane transports the upper NPM (now consisting of just the upper CNV with attached upper RPV) to the module inspection rack in the dry dock. Inspection, testing, and maintenance are performed while the core is being refueled using a dedicated fuel handling machine. After inspection, maintenance, and testing are complete and the reactor core has been refueled, the upper portion of the NPM is moved from the dry dock to the refueling pool where the NPM is reassembled in reverse order using the dedicated flange tools. Following reassembly, the NPM is moved into the reactor pool and returned to its operating bay by the RBC. In the operating bay, startup tests are performed and the reactor is prepared for restart. After the NPM has passed necessary tests and inspections, and the reactor coolant is at startup conditions, the NPM is brought online, and steam and power production begins. 2.2 Control Building The CRB is located approximately 30 ft east of the RXB. See Figure 1.2-21 through Figure 1.2-27 for CRB drawings. The overall CRB footprint is rectangular, approximately 120 ft long by 80 ft wide at the 100'-0" elevation. The following portions of the CRB are nonsafety-related and Seismic Category II:

• above the 120'-0" elevation
• inside the elevator shaft (full building height)
• inside the two stairwells (full building height)
• the fire protection vestibule located on the East side of the CRB 2 1.2-13 Revision 1

concrete structure. The lowest elevation of the CRB primarily houses electrical equipment and CRHS air bottles. There is a tunnel that connects the RXB to the CRB. However, the tunnel is for electrical equipment rather than personnel travel between the two buildings. The MCR and the associated spaces are located below grade in the CRB. This is the area serviced by the CRHS. Associated spaces for the MCR include the following:

• conference room (shift turnover)
• open office area (auxiliary operator room)
• two offices
• storage room
• janitor closet
• three air locks
• viewing area
• shift managers office
• reference room
• emergency equipment room
• lavatories
• break room
• telecommunication room A tunnel allows for personnel travel between the CRB and RXB.

The technical support center (TSC) and the associated spaces are located at grade level in the CRB. Associated spaces for the TSC include:

• records storage
• three offices
• two conference rooms
• data equipment room
• lavatories
• data maintenance room
• break room Additional equipment located in the CRB includes the control room HVAC system (CRVS) equipment, the chilled water system equipment supporting the CRVS, and an elevator machine room.

2 1.2-14 Revision 1

The MCR contains control panels for all installed NPMs. Each reactor operator monitors and controls multiple NPMs from a control room panel. Figure 18.7-1 provides the layout for the MCR. Digital control systems are implemented in a manner that provides independence between safety-related protection systems and nonsafety-related control systems. Each reactor control system display provides the monitoring for a specific reactor. Additional display stations, including a separate display for shared plant systems, provide control room operators with access to a wide range of plant information for trending and diagnostics. The reactor operators monitor the automated control system for each NPM. The MCR contains all alarms, displays, and controls for effective monitoring and control by the operators. The control room supervisor station provides an overview of all NPMs using multiple monitors. All monitor displays are designed using human factors analysis to enhance simplicity. The display layout and design uses graphical representations of plant systems and components. The following monitoring and control activities are typical control room functions:

• initiate NPM startup
• initiate NPM shutdown
• set or correct selected set points that control the NPM or plant functions
• take corrective actions if an NPM or plant system does not operate as intended The MCR enhances supervisory control of the NPMs and plant systems by providing alarm annunciation on the plant group-view overview display monitor as part of the alarm management system. This system includes information from the individual NPMs via the MPS, the MCS, and the shared I&C systems common to all the NPMs. In the event that the MCR becomes uninhabitable, a remote shutdown station in the Reactor Building provides a secondary location for safe shutdown of the reactors.

2.2.2 Technical Support Center A TSC is provided, compliant with the design requirements of NUREG-0696. Section 13.3 provides additional information. 2.3 Radioactive Waste Building The RWB houses equipment and systems for processing radioactive gaseous, liquid, and solid waste and for preparing waste for off-site shipment. See Figure 1.2-28 through Figure 1.2-33 for RWB drawings. The building houses equipment to prepare low-level radioactive waste for compaction to reduce volume and provides temporary storage for radioactive waste. HVAC equipment for high-efficiency particulate air filtration of air from the RXB and RWB is located in the RWB. The building is designed to 2 1.2-15 Revision 1

2.4 Major Systems 2.4.1 Decay Heat Removal System The DHRS provides secondary side reactor cooling for non-LOCA events when normal feedwater is not available. The system, as shown in Figure 1.2-8, is a closed-loop, two-phase natural circulation cooling system. Two trains of decay heat removal equipment are provided, one attached to each SG loop. Each train is capable of removing 100 percent of the decay heat load and cooling the RCS. Each train has a passive condenser immersed in the reactor pool. In the event of a SG tube failure, the affected SG is isolated and the DHRS provides cooling through the intact SG. On receipt of an actuation signal, feedwater and main steam isolation valves are closed and the DHRS valves open. Reactor coolant continues to circulate through the RPV collecting decay heat from the core. As water from the DHRS condenser travels through the SG tubes it is converted to steam absorbing decay heat from the reactor coolant. The steam then flows back to the DHRS condenser where it gives up excess heat to the reactor pool water and is condensed, and the cycle is repeated. This transfer of heat promotes natural circulation in both the RCS and the DHRS. Section 5.4.2 provides design and operational information for the DHRS. 2.4.2 Ultimate Heat Sink The ultimate heat sink is a large, stainless steel-lined, reinforced concrete pool located in the RXB below plant grade level. The ultimate heat sink consists of the reactor pool area, the refueling pool area, and the spent fuel pool area. The pool areas are shown in Figure 1.2-16. During normal plant operations, heat is removed from the pool through the reactor pool cooling system and rejected into the atmosphere through a cooling tower or other external heat sink. The spent fuel pool has an independent spent fuel pool cooling system. In a design basis accident involving a sustained loss of all AC power, decay heat is removed from the NPMs through passive heat transfer to the pool resulting in pool heat up and boiling. Water inventory in the reactor pool is adequate to cool the NPMs for at least 72 hours without adding water. The reactor pool provides an additional means of fission product retention beyond that of the fuel, fuel cladding, RPV, and the containment for certain events. Section 9.2.5 provides design and operational information for the ultimate heat sink. 2 1.2-16 Revision 1

The CVCS is simple in design and its operation is not credited during or after an accident. During normal operation, the CVCS recirculates a portion of the reactor coolant through demineralizers and filters to maintain reactor coolant cleanliness and chemistry. A portion of the recirculated coolant is used to supply pressurizer spray for controlling reactor pressure. Reactor coolant inventory is controlled by injection of additional water when reactor coolant levels are low or letdown of reactor coolant to the liquid radioactive waste system when coolant inventory is high. Additionally, during the NPM startup process, the CVCS is used in conjunction with the module heatup system, to add heat to the reactor coolant to establish natural circulation flow in the RCS. Boron concentration in the RCS is controlled by a feed-and-bleed process. Injection pumps provide borated water or clean demineralized water that is delivered into the RCS with excess reactor coolant being letdown to the radioactive waste system. Safety-related protection is provided for an anticipated operational occurrence involving unintended dilution of the RCS due to CVCS equipment failure or operating error. Section 9.3.4 provides design and operational information of the CVCS. 2.5 Other Site Structures 2.5.1 Turbine Generator Building A NuScale Power Plant has two separate TGBs. The TGBs are nonsafety-related structures. Each building houses six turbine generator sets along with their auxiliaries, the condensers, condensate systems, and the feedwater systems. A laydown area and overhead crane are provided for installation and maintenance activities in each TGB. 2.5.2 Annex Building The ANB is a nonsafety-related structure. The ANB houses several facilities and serves several functions, including:

• controlling access to both radiologically-controlled and nonradiologically-controlled areas of the RXB
• housing various personnel support services such as locker rooms, showers, toilet facilities, lunch and conference rooms, and first aid

        *   ((providing space for personnel and component decontamination equipment and employee dosimeter processing

• housing a portion of the facilities that support plant security such as secondary alarm station, security briefing room, armory, security manager's office, etc.))

2 1.2-17 Revision 1

The SCBs are non-safety related structures that include the following structures:

• primary access control building
• main security building
• vehicle barrier system The SCBs provide the following nonsafety-related functions:
• control personnel and vehicle entry into the PA and screen personnel seeking unescorted access into the PA.
• verify identity and access status as well as search for contraband items.
• provide a structure or space to monitor access into areas of the plant as well as monitoring tamper alarm devices.

2.5.4 Central Utility Building The CUB is a nonsafety-related structure that houses common utility plant services, which include the following:

     *   ((chiller equipment

• instrument air system
• service air system
• chemical treatment equipment for demineralized water

2.5.5 ((Diesel Generator Buildings The NuScale Power Plant design includes two DGBs, each housing a single backup diesel generator. The principal functions of each DGB are to provide support and housing for the backup diesel generators and their auxiliary equipment. The DGB houses no safety-related systems and has no functional requirements that support the ESFs. The DGBs house the following:

• diesel engines and associated support equipment
• generators

This section describes the verification and confirmation tests of unique design features that support the safety analysis for the NuScale Power Plant. The testing program described in this section was developed to provide data to support the final safety analyses. 1 NuScale Testing Programs The following testing programs have been completed or are currently in progress. The tests focus on design features of the NuScale Power Module (NPM) for which applicable data or operational experience did not previously exist. Tests specific to the NuScale fuel design are summarized in Section 1.5.1.1 and Section 1.5.1.2; tests specific to the steam generator (SG) are summarized in Section 1.5.1.3 and Section 1.5.1.4; tests specific to the control rod assemblies are summarized in Section 1.5.1.6 and Section 1.5.1.7; and tests involving integrated system phenomena are summarized in Section 1.5.1.5. 1.1 Critical Heat Flux Testing - Preliminary Fuel Design The NPM employs a fuel design for heat generation that is similar to a standard pressurized water reactor (PWR), with the exception of the fuel assembly height and the reactor coolant driving force. The NuScale fuel is approximately half the height of standard PWR fuel and features low-flow natural circulation of primary coolant rather than pump-driven primary coolant flow. In order to meet fuel licensing requirements, two critical heat flux (CHF) test programs were conducted: (1) a test program described in this section for the preliminary fuel design, and (2) a second test program described in Section 1.5.1.2 for the final fuel design. The preliminary fuel design test program supported code development and safety analysis efforts, and provided data for development of NuScale's NSP2 CHF correlation for the final fuel design. The NPM reactor core design employs 37 nuclear fuel assemblies. Each assembly is composed of a 17x17 square lattice of fuel rods assembled according to a given rod-to-rod pitch. Each fuel rod is approximately 2 meters in length. Fuel rods are assembled using spacer grids placed at specified locations along the length of the fuel rods such that fuel rods are evenly spaced and adequately supported. Primary coolant enters the NPM reactor core from the bottom through the core inlet plenum and heat transfer to the coolant occurs as coolant travels upward along the length of the fuel assemblies. In off-normal conditions, such as anticipated operational occurrences and postulated accidents, it must be known how close the heat transfer mode is to transitioning to a state where a continuous steam layer covers the fuel rods or portions of the fuel rods. The point at which this transition occurs is referred to as the CHF point. In order to determine the CHF point for the reduced-length fuel under appropriate flow conditions, a CHF testing program was conducted over a wide range of operating conditions. In these tests, instrumentation was used to measure key test parameters, including: resistance temperature detectors (RTD), thermocouples, pressure transducers, mass flow rate instruments, and electrical voltage and current meters. These sensors were used to measure heater rod temperatures and fluid flow conditions at various points of the fluid loop, and the electrical power supplied to heater rods when CHF occurred. The tests allowed NuScale to obtain fuel bundle subchannel exit temperatures to determine mixing coefficients and to obtain single-phase and two-2 1.5-1 Revision 1

and evaluation was collected. Testing for the preliminary fuel design CHF test series was performed at Stern Laboratories in Ontario, Canada using their existing high-pressure flow loop, electrical power supplies, heat rejection devices, water conditioning system, and data acquisition system. The test section and fuel simulators were designed and manufactured to represent the preliminary NuScale fuel design. Fuel assembly simulators with different axial power shapes were manufactured along with two sets of spacer grids that allowed testing of a 5x5 fuel assembly simulation bundle with or without the center fuel rod replaced by a guide tube. The approach of using a 5x5 representation of the larger 17x17 fuel assembly is an industry-accepted practice for CHF testing of PWR fuel bundles. The fuel assembly simulation bundles were mounted within a square flow channel and installed in the instrumented test section. This allowed testing of three separate configurations of fuel assembly simulation bundles with different axial flux shapes and fuel assembly subchannels as described in NuScale Power Critical Heat Flux Correlations topical report (TR-0116-21012). Tests were performed to envelope a range of bounding conditions and axial power shapes for vertical 5x5 fuel assembly configurations in accordance with the test specification and program documentation, which provided detailed test matrices for steady-state and transient CHF testing, pressure drop, and thermal mixing. The vertical 5x5 fuel assembly configurations were tested using industry-accepted test and acceptance methodology. The CHF testing was conducted by flowing water over the test sections at discrete test points covering a range of hydraulic conditions sufficient to develop a CHF correlation that spanned the NPM operational envelope. At each test point, the loop was configured for the specified flow, inlet temperature, and exit pressure conditions. The bundle power was increased until CHF was detected, which was indicated by an excursion of the fuel simulator thermocouples. Loop flow conditions (temperature, pressure, and flow), bundle power, rod power, and fuel simulator temperatures were recorded for each run. As-built data for the test section and test article, such as flow channel width, fuel simulator diameters, and spacer grid dimensions, were also recorded. In conclusion, tests were performed for a variety of thermal conditions using representative 5x5 fuel assembly simulations with a 2-meter heated length, differing axial power profiles, with and without a simulated guide tube. The testing investigated the effects of shorter fuel length and low-flow natural circulation of the primary coolant, and provided data that were used to develop NuScale's NSP2 CHF correlation in support of the NuScale small modular reactor technology. This test program was inspected by the NRC in accordance with Inspection Procedures IP 35034, 35017, and 36100. 1.2 Critical Heat Flux Testing - NuFuel HTP2' Fuel Design The primary objective for this test program was to obtain CHF data for the NuScale fuel design that employs AREVA HMP'/HTP' spacer grid technology (designated as 2 1.5-2 Revision 1

to develop NuScale NSP4 CHF correlation and to validate NuScale's NSP2 CHF correlation developed using the preliminary fuel design tests for the NPM application. In addition, this test allowed NuScale to obtain bundle subchannel exit temperatures to determine mixing coefficients, and to collect single-phase and two-phase pressure drop characteristics of the assembly for a range of bundle powers and hydraulic conditions. The CHF test employed an electrically-heated test section that consisted of a 5x5 simulated fuel bundle built to prototypic geometry and employing AREVA HTP'/ HMP' grid technology. The fuel assembly simulators with different power shapes were tested using a 5x5 fuel bundle with or without the center fuel rod replaced by a guide tube. The testing was conducted by flowing water through the test section at specified flow rates over a range of hydraulic conditions of the NPM. At each test point, the loop was configured for a specified flow rate, inlet temperature, and exit pressure conditions, and the bundle power was increased until CHF was detected over a range of operating conditions and axial power shapes for vertical 5X5 fuel assembly configurations. The occurrence of CHF was indicated by an excursion of the fuel simulator temperatures. The prototypic fuel design tests were conducted at the AREVA Karlstein Thermal Hydraulics (KATHY) facility located in Karlstein, Germany. The test data was used to validate the applicability of NuScale's NSP2 CHF correlation and to develop the NSP4 correlation for the NuFuel HTP2' fuel design. 1.3 Steam Generator Thermal-Hydraulic Performance Testing - Electrically Heated Facility The NPM incorporates two collocated SGs housed within the reactor pressure vessel. The SGs provide heat transfer to and from the primary system for both normal and off-normal conditions. Through natural circulation, the reactor coolant system transfers the core power to the SG converting feed water into steam. Unlike current PWR designs, the reactor coolant flows around the outside of the SG tubes (primary side) and the feedwater and main steam flow through the inside of the tubes (secondary side). Because these design aspects of the helical SGs are different from those used in the nuclear fleet, operational experience is not available and large-scale experimental data were needed for validation of NuScale thermal-hydraulic systems and design computer codes, as well as determination of SG performance characteristics. The objective of this testing was to determine the secondary side (inside tube) thermal-hydraulic performance of individual helical tubes representative of those used in the NPM steam generator design. This required testing over a range of conditions representative of the operational envelope. Measurement data were required to evaluate the distribution of temperature and pressure on the inside of the tubes. The electrically-heated test focused on secondary-side performance and consisted of three isolated tubes that were instrumented with well-controlled boundary conditions. Heating was accomplished using Joule heating, wherein a known electrical current is passed through the tube walls to produce a constant heat flux boundary condition on 2 1.5-3 Revision 1

zone the heat flux was constant, which represents a simplification from the heat flux profile that results when fluid heating is employed, as would occur in an operating NuScale SG. This approach enabled tube wall heat flux to be controlled during testing and permitted better access to instrumentation on the outside of the tubing. The testing was performed at the Societ Informazioni Esperienze Termoidrauliche (SIET) test facility in Piacenza, Italy. Types of testing carried out included adiabatic testing, diabatic testing, transient testing, and density wave oscillation testing. Dynamic pressure measurements were recorded during test runs which supported development of power spectral density spectra that may be used to support evaluation of the potential for internal two-phase (boiling) pressure fluctuations to contribute to flow induced vibration of SG tubes. These data also were used to inform sizing of the SG inlet flow restrictors for stable secondary-side SG operation, to provide benchmarking for NuScale thermal-hydraulic design and systems computer codes, and to define steam outlet conditions as a function of primary heat generation and secondary side conditions. This test program was inspected by the NRC in accordance with Inspection Procedures IP 35034, 35017, and 36100. 1.4 Steam Generator Thermal-Hydraulic Performance Testing - Fluid-Heated Facility Subsequent to the SG tests described in Section 1.5.1.3 that used three electrically heated SG tubes, a second set of SG tests was conducted using a 252-tube bundle array that was fluid heated on the exterior of the tubes to more accurately represent primary side SG conditions. The test facility included a large pressure vessel, which was able to accommodate the tube bundle test section and allowed for testing at elevated pressures and temperatures. The test facility included heaters and pumps that provided a span of flow rates at a wide range of thermal-hydraulic conditions. The fluid-heated test focused on overall primary and secondary side performance, and consisted of a bank of 252 helical tubes, modeling five of the 21 helical coil columns, operated at near-prototypic primary- and secondary-flow conditions. Testing activities were conducted at SIET in Piacenza, Italy using their fluid-heated hydraulic loop. Types of testing carried out included: adiabatic, diabatic, transient, density wave oscillation, and fluid-elastic instability tests. Each type of test consisted of multiple test points covering a range of conditions to characterize the phenomena of interest at various combinations of primary-side and secondary-side pressures, temperatures, and flow rates. In these tests, thermocouples, pressure transducers, mass flow rate instruments, and strain gauges were used to collect temperature, pressure, flow rate, and vibration data at several locations on the primary and secondary sides of the SG. These data have been used to benchmark NuScale thermal-hydraulic design and systems computer codes, and to define steam outlet conditions as a function of primary-fluid heating and secondary-side conditions. 2 1.5-4 Revision 1

The purpose of the NuScale integral system test program was to generate thermal-hydraulic data for system characterization and safety code validation using a scaled representation of the NPM design. Tests have also informed safety methodology development. The NuScale Integral System Test Facility (NIST-1) allows NuScale to replicate the integrated thermal-hydraulic phenomenon occurring in the reactor coolant system, containment, safety systems, and reactor pool. Data collected provide system characterization data required for validation of safety-related software, NRELAP5 and PIM. The NRELAP5 code, which is based on a commercial version of RELAP5-3D, is a thermal-hydraulic analysis code developed at NuScale for use in the thermal-hydraulic design, safety analysis, and licensing of the NPM. The code incorporates models and correlations specific to the unique design features of the NPM. The PIM code is a NuScale-developed proprietary code used to assess the stability characteristics of the NPM during operation. The NIST-1 is a scaled representation of the NPM reactor, containment, and reactor pool systems. It is constructed of stainless steel and has a maximum operating pressure of 1650 psia (11.4 MPa) and temperature of 630 degrees F (605 degrees K). NIST-1 volumes, lengths, and areas are obtained by multiplying the respective NPM design volumes, lengths, active heat transfer areas, and flow areas by the applicable scale factors determined through a detailed scaling analysis. This process ensures the NIST-1 properly captures the important thermal-hydraulic phenomena and processes that would occur in the plant. A series of tests have been completed at the NIST-1, located on the Oregon State University campus in Corvallis, OR, in support of NuScale's Design Certification Application. These tests include:

• facility characterization tests used to develop the NRELAP5 model of the NIST-1.
• loss-of-coolant accident (LOCA) tests used to validate NRELAP5 for LOCA and containment analyses.
• flow-stability tests used to validate PIM for reactor stability analyses.
• non-LOCA (anticipated operational occurrence) tests used to validate NRELAP5 for non-LOCA analyses.
• long-term cooling tests used to validate NRELAP5 for long term cooling analyses.

Data obtained from the NIST-1 tests identified above have been used to successfully validate the NRELAP5 and PIM codes for LOCA and containment, non-LOCA, flow stability, and long term cooling applications. This test program was inspected by the NRC in accordance with Inspection Procedures IP 35034, 35017, and 36100. 1.6 Control Rod Drive Mechanism Proof Test The control rod drive mechanism for the NPM contains features that are not common in conventional control rod drive mechanisms: a remote disconnect mechanism and a 2 1.5-5 Revision 1

and repeatability of each system. Additional testing to determine misalignment limits is described in Section 1.5.1.7. Testing was completed at the Curtiss Wright facilities in Cheswick, PA, for both remote connect and remote disconnect operation of the coils. The test setup included a functional drive rod assembly, a prototypic remote disconnect gripper coil, a prototypic remote disconnect gripper latch, a prototypic lift coil, and weights to simulate the control rod assembly (CRA) with a prototypic CRA hub socket. The remote disconnect mechanism was found to provide a reliable and repeatable method to engage and disengage the CRA within the reactor pressure vessel. This is consistent with the results of the remote operation, lift verification, and manual disengagement testing that was performed. The tests provided a demonstration of hardware performance, which has been extended to aid in the design of drive rod position detection circuitry. Information gained from this testing has been used as a development tool to improve the design and does not create a design basis for the final control rod drive mechanism. 1.7 Control Rod Assembly Drop and Control Rod Drive Shaft Alignment Test The NPM is designed with control rod drive shafts that are longer than conventional PWR designs and have the capability to be remotely disconnected. The control rod drive shafts are aligned using the following multiple-support features:

• control rod drive mechanism nozzles in the reactor vessel head
• integrated steam plenum
• five upper control rod drive shaft supports in the upper riser section
• a control rod drive shaft alignment cone located at the top of the CRA guide tube The design uses a CRA and fuel-assembly design similar to, but shorter than, traditional operating reactors. The arrangement of a shorter fuel assembly and CRA coupled to a longer control rod drive shaft creates a unique configuration of these components with no operational or testing experience. The CRA-drop and control rod drive shaft-alignment test program was developed to confirm the operability of this unique design.

Testing is to be performed at the AREVA Technical Center in Erlangen, Germany, and is configured as an ambient pressure and temperature test. The ambient test configuration is composed of a full-length control rod drive shaft coupled with a NPM control rod assembly and fuel assembly, as well as the control rod drive shaft support structures and a CRA guide tube assembly. The CRA guide tube assembly and fuel assembly are immersed in the water under ambient conditions with no coolant flow. During the test, the coupled CRA and control rod drive shaft assembly is dropped using multiple configurations having variations in the alignment of the control rod drive shaft supports and CRA guide tube assembly and a mid-span deflection of the fuel assembly. 2 1.5-6 Revision 1

provide CRA drop time and CRA impact velocity at end of drop. 2 NuScale Test and Inspection Plans Information on NuScale test and inspection plans related to plant startup testing is provided in Section 14.2. 2 1.5-7 Revision 1

This section addresses interface requirements between the NuScale Power Plant certified design and the site-specific design provided in the combined license (COL) application. Section 1.2 identifies the structures, systems, and components that are included in the certified design. Figure 1.2-1 provides a representation of the overall facility and Figure 1.2-2 provides the general boundaries between the certified design and site-specific design. Table 1.8-1 identifies the interfaces between the NuScale certified design and the site-specific design. There are two types of interface requirements described:

• CDI: Conceptual design information that is provided for the non-certified portion of the plant to facilitate review of the certified design and to confirm the adequacy of identified interface requirements.
• COL: NuScale design assumptions related to site-specific design elements that are the responsibility of the COL applicant. This type of interface is identified as a COL information item.

1 Combined License Information Items Information that must be provided in order to license and operate a site-specific NuScale Power Plant, but is not included in the certified design, is identified throughout the Final Safety Analysis Report as COL information items. Table 1.8-2 lists the COL information items, includes the COL information item text and identifies the section where the information item is located.

This evaluation also includes an identification and description of deviations from the guidance in the NRC Regulatory Guides as well as suitable justifications for any alternative approaches proposed. The conformance evaluation was performed on the following groups of Regulatory Guides:

• Division 1, Power Reactors
• Division 4, Environmental and Siting (applies to the environmental report and should be discussed therein)
• Division 5, Materials and Plant Protection (applies to the security plan and should be discussed therein)
• Division 8, Occupational Health 2 1.9-1 Revision 1

NuScale performed a review of the SRP including Branch Technical Positions and guidance referenced within the SRP. A summary of this review was submitted to the NRC as NP-RT-0612-023, "Gap Analysis Summary Report," Revision 1, in July 2014 (Reference 1.9-1). The gap analysis review for applicability was directed towards the acceptance criteria of each SRP section. However, the review considered the relevance of sub-tier guidance whether referenced in the acceptance criteria or in other portions of the SRP section being reviewed. Additionally, NuScale considered conformance with the DSRS developed by the NRC for the review of the NuScale Power small modular reactor design. This information has been incorporated into Table 1.9-3. Conformance with NRC Interim Staff Guidance is presented in Table 1.9-4. 3 Generic Issues In accordance with 10 CFR 52.47(a)(8), conformance is assessed against technically relevant Three Mile Island (TMI) requirements identified in 10 CFR 50.34(f), except for paragraphs (f)(1)(xii), (f)(2)(ix), and (f)(3)(v). Plant characteristics and plant programs that address relevant TMI requirements are described in the appropriate FSAR sections. In accordance with 10 CFR 52.47(a)(21), proposed resolutions must be identified for any technically relevant unresolved safety issues and medium-priority to high-priority generic safety issues (GSI) identified in the version of NUREG-0933 that is current six months prior to the application for design certification. Resolution and closure of generic issues is managed via the NRC Generic Issues Program. NRC SECY-07-0110, dated July 6, 2007 provides the most recent supplemental status report of the Generic Issues Program prior to the FSAR submittal. As such, Appendix B of NUREG-0933, Rev. 21 (including the Main Report and Supplements 1-34) and NRC letter SECY-07-0110, were used to identify those generic issues applicable to the NuScale Power Plant design certification. Table 1.9-5 identifies the applicable TMI requirements and generic issues, along with an abbreviated summary description of the NRC position for each table entry. Table 1.9-5 also provides a brief conformance assessment notation, including annotation of any exceptions, and a reference to the FSAR section(s) addressing the issue. Those NUREG-0933 generic issues determined as non-applicable were eliminated from consideration in Table 1.9-5 based on these:

• Resolved: Issue has been completely resolved and removed from the latest Generic Issues Program list of Active and Regulatory Office Implementation Generic Issues.
• BWR, Ice Condenser Containment or Other: Issue applies to another nuclear power plant design concept or to the design of a nuclear facility other than a nuclear power plant.

4 Operational Experience (Generic Communications) Per 10 CFR 52.47(a)(22) requirements, applicants for design certification of new plant designs include a description of how operational experience has been incorporated into the design process. Operational experience insights are incorporated into applicable SRP 2 1.9-2 Revision 1

application docket date are incorporated into the design unless stated otherwise. The design is an evolution of nuclear power plant designs that have been operated in the United States, as addressed by 10 CFR 52.41(b)(1); hence NRC guidance for technically relevant operational experience issues is addressed in the appropriate FSAR sections. The conformance assessment relative to operational experience is provided in Table 1.9-6, "Evaluation of Operating Experience (Generic Letters and Bulletins)." Further, 10 CFR 21 notifications were reviewed for impact to the NuScale design as part of the supplier evaluation process. NuScales QA supplier evaluation program includes a review of 10 CFR 21 notifications for every Nuclear Safety Related supplier prior to use as an approved supplier for safety related items/services. The evaluation for any 10 CFR 21 notifications is also performed as part of monitoring of supplier performance by periodic annual review. There have been no 10 CFR 21 notifications impacting nuclear safety related work performed by NuScale approved safety related suppliers for the development of the NuScale Design. Therefore, all applicable 10 CFR 21 notifications have been evaluated. 5 Advanced and Evolutionary Light-Water Reactor Design Issues Guidance in SRP Section 1.0 recommends that this section address the applicable licensing and policy issues developed by the NRC and documented in SECY-93-087, "Policy, Technical, and Licensing Issues Pertaining to Evolutionary and Advanced Light-Water Reactor (ALWR) Designs," Secretary of the Commission, Office of the U.S. Nuclear Regulatory Commission, April, 2, 1993, as supplemented by the associated staff requirements memorandum (SRM) dated July 21, 1993.

formance Status Description Code forms The regulation or regulatory guidance is relevant and applicable, and can be applied as-is. The design fully conforms to the requirement or guidance described in the Section(s) identified. Where options are identified in the regulation or regulatory guidance, Conforms indicates that the design fully conforms to the option(s) selected. ially Conforms The design conforms to those portions of the requirement or guidance that can be appropriately applied as written. The underlying purpose or intent of the requirement or guidance is relevant to the design but cannot be appropriately applied as written, or some portion of the requirement or guidance is applicable while other portions are not applicable. The following are examples:

• A portion of the regulatory requirement or guidance is literally applicable, but the specific language refers to a different type of light water reactor (LWR) design or structures, systems, and components (SSC) that are not part of the design.
• The regulatory requirement or guidance is applicable except for aspects that are specific to combined license or early site permit applicants, or to BWR designs, etc.
• The intent of a regulatory requirement or guidance is applicable, but the specific language refers to one of the following:

                 - a different type of LWR design
                 - an SSC that is not part of the design, but for which a substantively equivalent function is served by other SSC within the design Applicable      The regulation or guidance is not appropriate to apply and therefore conformance is not required.

The following are examples:

• The regulatory requirement or guidance is applicable only to BWR designs.
• The regulatory requirement or guidance is applicable only to large pressurized water reactor (PWR) designs.
• The regulatory requirement or guidance is applicable to the design, but is the responsibility of the COL applicant.
• The regulatory requirement or guidance is applicable to SSC that are not part of the design.

arture For items found within the Code of Federal Regulations (CFR): the regulation is literally applicable; however NuScale intends to depart from the regulation based on the design or safety basis of the NuScale design. That is to say that conformance to the regulation would have a minimal, or even negative, impact on safety of the NuScale design and hence a departure from the regulation (that was originally created for traditional LWRs) is warranted. The form of the departure may be through an exemption request under 10 CFR 52.7 or through a specific process available for a set of regulations. For example, the introduction to 10 CFR 50, Appendix A provides a departure from the General Design Criteria as explained in Section 3.1, and the TMI action items may be identified and justified as not technically relevant to the design consistent with 10 CFR 52.47(a)(8) and 10 CFR 50.34(f).1 1 Note that some TMI action items are categorized as Partially Conforms or Not Applicable rather than Departure. The difference is that those requirements are not applicable by their own terms, for example because they apply to BWRs or to an SSC that the NuScale design lacks. A departure from a TMI requirement is appropriate where the requirement is literally applicable but is inappropriate to apply to the NuScale design. 2 1.9-4 Revision 1

However, the NuScale design is significantly different from the system designs the guidance addresses. The NuScale design complies with the guidance with respect to debris generation, debris transport, coating debris, latent debris, downstream and chemical effects. The NuScale design is passive and does not include pumps, sumps, suction strainers, debris interceptor or trash racks and the design minimizes or negates the potential effect of non-condensables on coolant flow to the core. The NuScale design also does not require operator action to mitigate debris accumulation. The NuScale design does not comply with regulatory position C1.1 with the exception that NuScale does comply with the intent of the following regulatory positions:

Specifically, this guidance provides methodology for evaluation of loading transients and structural components, including containment subcompartment analysis, when a double-ended guillotine break of reactor coolant loop piping occurs at the reactor vessel inlet. The NuScale containment vessel design does not have subcompartments. In addition, the NuScale design does not have reactor coolant loops. Notwithstanding the above, this guidance is applicable to the evaluation of loading transients and structural components for postulated breaks of chemical and volume control system (CVCS) piping and piping at the reactor vent valves. 3.9.5, Rev 3: Reactor II.6 Effects of Flow-Induced Vibration and Partially Conforms This acceptance criterion (including 3.9.5 sure Vessel Internals Acoustic Resonances (Including Appendix A) is applicable except for aspects Appendix A) that are BWR-specific. 3.9.6, Rev 3: Functional II.1 Functional Design and Qualification Partially Conforms This acceptance criterion is applicable 3.9.6 gn, Qualification, and of Pumps, Valves, and Dynamic except for aspects related to functional Conformance with Regulatory Criteria vice Testing Programs Restraints design, qualification, and testing of safety-umps, Valves, and related pumps.

Notwithstanding the above, pursuant to 10 CFR 52.47(a)(11) and consistent with DSRS 16.0, the DCA contains proposed technical specifications that are prepared in accordance with 10 CFR 50.36 and 10 CFR 50.36a. The improved standard technical specification guidance for LWRs specified in this DSRS - NUREGs-1430 through -1434, and NUREG-2194 - were utilized to the extent appropriate and practicable. Additionally, the Technical Specifications Task Force Writers Guide for Plant-Specific Improved Technical Specifications, TSTF-GG-05-01, Revision 1, August 2010 was used to draft the Conformance with Regulatory Criteria specifications. There are a number of technical and editorial differences between the NuScale proposed technical specifications and those presented in the improved standard technical specifications. Consistent with this DSRS 16.0, technical justification for such differences is provided.

Also, while the DHRS AFW system flow indication in the control room performs some of the functions of an AFW system at a (II.E.1.2) PWR, the NuScale DHRS is designed for NuScale-specific transients and system characteristics, and its actuation and indication is designed accordingly. Specifically with regard to the portion of this requirement specifying control room flow indication, the DHRS operation involves passive natural circulation flow, with flow characteristics that vary with system conditions, which makes DHRS flow a less useful measurement for the NuScale design. Control room indication for system parameters other than DHRS flow are more appropriate to ensure operators have the information necessary to adequately monitor DHRS operation and reactor core cooling. These parameters include DHRS pressure, valve position indication, and reactor coolant system pressure and temperature. 10 CFR 50.34(f)(2)(xii) is not considered applicable to the NuScale DHRS. Because the language and intent of 10 CFR 50.34(f)(1)(ii) do not apply, the requirement is not applicable to the NuScale design.
