DESIGN CRITERIA ctures, systems, and components (SSCs) present in the SHINE facility are identified in les 3.1-1 and 3.1-2, including the applicable FSAR section(s) which describe each SSC and applicable SHINE design criteria. Design criteria derived from external codes, guides, and dards specific to the design, construction, or inspection of SSCs are included in the licable FSAR section describing those SSCs. For each SSC, the FSAR section identifies tion, function, modes of operation, and type of actuation for specific SSCs, as applicable.
lear Safety Classification ety-related SSCs at SHINE are those physical SSCs whose intended functions are to prevent idents that could cause undue risk to health and safety of workers and the public; and to trol or mitigate the consequences of such accidents.
eptable risk is achieved by ensuring that events are highly unlikely or by reducing sequences less than the SHINE safety criteria. The SHINE safety criteria are:
- An intake of 30 milligrams or greater of uranium in a soluble form by any individual located outside the owner controlled area.
- An acute chemical exposure to an individual from licensed material or hazardous chemicals produced from licensed material that could lead to irreversible or other serious, long-lasting health effects to a worker or could cause mild transient health effects to any individual located outside the owner controlled area.
- Criticality where fissionable material is used, handled, or stored (with the exception of the target solution vessel).
- Loss of capability to reach safe shutdown conditions.
me SSCs are nonsafety-related but perform functions that impact safety-related SSCs. These safety-related SSCs have design basis requirements necessary to prevent unfavorable ractions with safety-related SSCs due to failure of the nonsafety-related SSCs.
ety-related SSCs are identified in Table 3.1-1 and nonsafety-related SSCs are identified in le 3.1-2.
NE Design Criteria SHINE facility uses design criteria to ensure that the SSCs within the facility demonstrate quate protection against the hazards present. The design criteria are selected to cover:
- The complete range of irradiation facility and radioisotope production facility operating conditions.
- The response of SSCs to anticipated transients and potential accidents.
- Design features for safety-related SSCs including redundancy, environmental qualification, and seismic qualification.

manmade or natural conditions.
- Quality standards.
- Analyses and design for meteorological, hydrological, and seismic effects.
- The bases for technical specifications necessary to ensure the availability and operability of required SSCs.
SHINE design criteria are described in Table 3.1-3.
terms used in Table 3.1-3 include primary system boundary, primary confinement boundary, process confinement boundary, which are defined in Sections 4a2.2, 6a2.2, and 6b.2, pectively.

tornado differential pressure is defined in Regulatory Guide 1.76, Table 1 as 1.2 pounds per are inch (psi) (8.3 kilopascals [kPa]) for Region I (USNRC, 2007a). The tornado differential ssure is applied as an outward pressure to the exterior walls of the building, as well as the

2.3 Effect of Failure of Structures, Systems, or Components Not Designed for Tornado Loads Cs whose failure during a tornado event could affect the safety-related portions of the facility either designed to resist the tornado loading or the effect on the safety-related structures the failure of these SSCs or portions thereof are shown to be bounded by the tornado sile or aircraft impact evaluations.
Seismic Category I boundary provides missile walls to protect safety-related systems from age due to tornado missiles. SSCs that are credited to prevent or mitigate potential idents caused by a tornado event are protected by the design of the enclosed structure. The ctural analysis does not credit venting of the Seismic Category I boundary during a tornado nt. The differential pressure on all surfaces as an enclosed structure results in higher ssures, and the differential pressure would be reduced by the effects of venting. Therefore, e are no consequences to venting the building during a tornado event.
3 SNOW, ICE, AND RAIN LOADING subsection discusses the criteria used to design the main production facility to withstand ditions due to snow, ice, and rain loading. Rain loading is not considered in the structural ign of the building as the sloped roofs do not result in rain accumulation. As a result of the of rain accumulation, load due to ice is anticipated to be minimal and is enveloped by the ign snow load.
3.1 Applicable Design Parameters w load design parameters pertinent to the main production facility are provided in Chapter 7 SCE 7-05 (ASCE, 2006) and adjusted for a mean recurrence interval of 100 years, per le C7.3 of ASCE 7.05 (ASCE, 2006).
3.2 Determination of Applied Forces sloped roof snow load is calculated in accordance with Sections 7.3 and 7.4 of ASCE 7-05 CE, 2006). The combined equation utilized to calculate the sloped roof load is:

design basis precipitation, flood levels, and ground water levels for the main production lity are as follows:
- Design basis flood level: 50 feet (ft.) (15.2 meters [m]) below grade.
- Design basis precipitation level: at grade.
- Maximum ground water level: 50 ft. (15.2 m) below grade.
Subsection 2.4.2.3, a design basis rainfall event creates a water level about level with grade.
first floor of the building is at least 4 inches (in.) (10.2 centimeters [cm]) above grade; efore, water will not infiltrate the door openings in the case of a design basis rainfall event.
Subsection 2.4.3, a local probable maximum flood (PMF) event creates a water level roximately 50 ft. (15.2 m) below grade. The water elevation for the PMF is derived from MA flood profiles. The lowest point of the facility is 26 ft. (7.9 m) below grade; therefore, ding does not cause any structural loading in the case of a local PMF event.
impact of internal flooding is determined by the maximum flow rate and the volume of water ilable to feed the flood. No active response is assumed to terminate the flow and the entire me of available water is assumed to spill into the main production facility. For water sources ide the building (fire water), automatic or operator actions are required to terminate the flow.
ms and ramps are used within the facility to:
- Capture and contain water collected in the RCA resulting from postulated water system ruptures or fire system discharges above grade.
- Prevent water intrusion into the uranium receipt and storage system (URSS) and target solution preparation system (TSPS) rooms.
- Prevent a release of water from the RCA due to the postulated failure of the radioisotope process chilled water system (RPCS) room, the process chilled water system (PCHS), or the facility demineralized water system (FDWS).
- Prevent bulk release of water into the radioactive drain system (RDS) sump tanks thereby overfilling the sump collection piping.
ety-related equipment vulnerable to water damage is protected by locating it in flood-ective compartments and/or installing it above flood elevation.
1 FLOOD PROTECTION subsection discusses the flood protection measures that are applicable to safety-related Cs for both external flooding and postulated flooding from failures of facility components taining liquid.
lyses of the worst flooding due to pipe and tank failures and their consequences are ormed in this subsection.
NE Medical Technologies 3.3-1 Rev. 2
tulated flooding from component failures in the building compartments is prevented from ersely affecting plant safety or posing any hazard to the public. Exterior or access openings penetrations into the main production facility are above the maximum postulated flooding l and thus do not require protection against flooding.
1.1.1 Flood Protection from External Sources ety-related components located below the design flood level are protected using the dened protection approach described below. The safety-related systems and components are d-protected because they are enclosed in a reinforced concrete safety-related structure, ch has the following features:
- a. Exterior walls below flood level are not less than 2 ft. (0.61 m) thick.
- b. Water stops are provided in construction joints below flood level.
- c. Waterproofing is applied to external surfaces exposed to flood level.
- d. Roofs are designed to prevent pooling of large amounts of water.
erproofing of foundations and walls of Seismic Category I structures below grade is omplished principally by the use of water stops at construction joints.
ddition to water stops, waterproofing of the main production facility is provided up to 4 in.
2 cm) above the plant ground level to protect the external surfaces from exposure to water.
1.1.2 Flood Protection from Internal Sources suppression systems within the RCA consist of manual discharge via fire hoses from dry dpipes, except in those areas of the RCA in which gaseous fire suppression is provided, as cribed in Section 9a2.3. The total discharge from the fire protection discharge consists of the bined volume from any firefighting hoses. In accordance with National Fire Protection ociation (NFPA) 801, Section 5.10 (NFPA, 2008), the credible volume of discharge is sized a manual fire-fighting flow rate of 500 gallons per minute (1893 liters per minute) for a ation of 30 minutes (min.). Therefore, the total discharge volume is 15,000 gallons 782 liters). This bounds the total water available in the PCHS and RPCS cooling systems could cause internal flooding. When the total discharge volume of fire water is distributed r the entire RCA, the depth is less than 2 in. (5.1 cm). When the total discharge volume of fire er is distributed only over the minimum open floor area in the irradiation facility (IF), the depth ss than 12 in. (30.5 cm).
safety-related function(s) of systems within the RCA that are subject to the effects of a harge of the fire suppression system are appropriately protected by redundancy and aration. Where redundant equipment is unable to be effectively separated, fire response s are established to ensure redundant trains of water sensitive safety-related equipment are both subject to damage due to discharge of the fire suppression system. The floors of the SS/TSPS rooms are elevated to prevent water intrusion in the event of an internal flood.
er sensitive safety-related equipment is raised from the floor a minimum of 12 in. (30.5 cm) in RCA, with the exception of the RPCS room, where water sensitive safety-related equipment ised a minimum of 24 in. (61.0 cm) from the floor to provide defense in depth. Therefore, the NE Medical Technologies 3.3-2 Rev. 2
side of the RCA there is limited water discharge from fire protection systems. The safety-ted function(s) of systems outside the RCA that are subject to the effects of a discharge of fire suppression system are appropriately protected by redundancy and separation. The terruptible electrical power supply system (UPSS) has two trains to provide redundancy.
se trains are isolated from each other to prevent one train from being damaged by discharge he fire protection system in the vicinity of the other train. Any water sensitive safety-related ipment outside the RCA is installed a minimum of 8 in. (20.3 cm) above the floor slab at de.
od scenarios have been considered for the pipe trenches and vaults. Process piping, vessels, tanks containing special nuclear material (SNM) or radioactive liquids are seismically lified. There is no high-energy piping within these areas. Any pipe or tank rupture in the oisotope production facility (RPF) vaults is routed to the radioactive drain system (RDS). The S is sized for the maximum postulated pipe or tank failure as described in Subsection 9b.7.6.
design of the shield plugs over the pipe trenches and vaults prevents bulk leakage of liquid the vaults from postulated flooding events within the remainder of the RCA.
light water pool in the irradiation unit cell (IU) is filled to an elevation approximately equal to top of the surrounding area floor slab. Given the robust design of the light water pool proximately 4 ft. thick reinforced concrete) and the stainless steel liner, loss of a significant ount of pool water is not credible.
1.2 Permanent Dewatering System re is no permanent dewatering system provided for the flood design.
2 STRUCTURAL DESIGN FOR FLOODING ce the design basis rainfall event elevation is at the finished plant grade and the PMF ation is approximately 50 ft. (15.2 m) below grade, there is no dynamic force due to cipitation or flooding.
load from build-up of water due to discharge of fire water in the RCA is supported by slabs grade, with the exception of the mezzanine floor. Openings that are provided in the zzanine ensure that the mezzanine slab is not significantly loaded. The mezzanine floor slab esigned to a live load of 250 pounds per square foot (1221 kilograms per square meter).
refore, the mezzanine floor slab is capable of withstanding temporary water collection that y occur while water is draining from the mezzanine floor.

smic analysis criteria for the main production facility structure (FSTR) are supported by the ailed guidance provided by the referenced Regulatory Guides and sections of NUREG-0800, ndard Review Plan for the Review of Safety Analysis for Nuclear Power Plants (SRP).
FSTR includes the irradiation facility (IF), the radioisotope production facility (RPF), the
-radiologically controlled seismic area, and a nonsafety-related area. The IF contains the diation units (IUs) and tritium purification system (TPS), and the RPF contains the supercell below-grade tanks. The non-radiologically controlled seismic area contains the control room, ery rooms, uninterruptible electrical power supply rooms, and other miscellaneous support ms. The RPF, IF, and non-radiologically controlled seismic area are within the seismic ndary and are classified as Seismic Category I. These areas contain the safety-related ctures, systems, and components (SSCs). To the south of the seismic boundary are the ping and receiving areas, as well as other areas that contain nonsafety-related support tems and equipment. This part of the structure is not Seismic Category I. The areas outside seismic boundary do not contain safety-related SSCs.
IF, RPF, and non-radiologically controlled seismic area comprise the safety-related portion he FSTR. The dimensions of the safety-related portion of the FSTR at grade level are roximately 212 feet (ft.) (64.6 meters [m]) in the north-south direction and 158 ft. (48.2 m) in east-west direction. Each of the three main areas of the safety-related portion of the FSTR is arallel, single-story box-type structure designed with cast-in-place reinforced concrete shear
- s. The major structural elements include the foundation mat, mezzanine floor, roof slab, and ar walls. Depending on their function, interior walls are cast-in-place reinforced concrete, forced masonry, or gypsum mounted to metal studs.
IF and RPF have a shared sloped main roof slab with a low point elevation of approximately
- t. (13.7 m) and a high point elevation of approximately 56 ft. (17 m). The IF and RPF roof ensions are approximately 212 ft. (64 m) in the north-south direction and 126 ft. (38.4 m) in east-west direction. The IF and RPF roof slab is 12 inches (in.) (0.3 m) thick and has a 5 in.
3 m) thick leave-in-place form slab on metal deck beneath it. The IF and RPF roof slab is ported by a series of roof trusses, which are made out structural steel shapes having a yield ngth of 50 kilopounds per square inch (ksi) (6.89 MPa).
non-radiologically controlled seismic area roof slab is 20 in. (0.51 m) thick and has a high t elevation of approximately 22 ft. (6.71 m). The non-radiologically controlled seismic area dimensions are approximately 148 ft. (45.1 m) in the north-south direction and 32 ft. (9.75 m) e east-west direction.
rior to the IF and RPF there is a mezzanine with 8 in. (0.2 m) thick reinforced concrete slab metal deck, vertically supported by structural steel beams and columns (structural shapes yield strength of 50 ksi [6.9 MPa]), and laterally restrained by interior reinforced concrete

The exterior above grade walls and major shear walls range from inimum of 2 ft. (0.61 m) thick to a maximum of 2.33 ft. (0.71 m) thick. The reinforced concrete ctures are founded on a 3 ft.

5 m) in the north-south direction and 158 ft. (48.2 m) in the east-west direction. Additionally, southwest corner of the safety-related basemat contains a part of the nonsafety-related ion of the FSTR. The dimensions of this nonsafety-related part are approximately 63 ft.
2 m) in the north-south direction and 32 ft. (9.8 m) in the east-west direction. The safety-ted portion of the FSTR is seismically isolated from the nonsafety-related portion of the FSTR a seismic separation joint (i.e., seismic gap).
nonsafety-related portion of the FSTR is a two-story steel framed structure with a roof height pproximately 40 ft. (12.2 m). The concrete on metal deck mezzanine slab and metal deck roof are diaphragms that transfer the lateral loads to a series of vertical brace systems. The R also includes a nonsafety-related, isolated, self-supporting steel on reinforced-concrete ndation cantilevered exhaust stack with a height of approximately 67 ft. (20.4 m) located east he nonsafety-related portion of the FSTR.
FSTR is modeled to the analyses described in this chapter. The concrete walls, slabs, and emat are modeled using thick shell elements. The steel structural members are modeled g three-dimensional beam elements. Interior partition walls made of concrete are modeled g thick shell elements. Interior partition walls made of masonry or gypsum are isolated from lateral load resisting system of the building and are not explicitly modeled, but their mass is ounted for. Interior partition walls that are co-located with safety-related SSCs, and must ntain structural integrity to prevent unacceptable interactions with safety-related SSCs, are sified as Seismic Category II. The excavated soil volume of the soil-structure interaction I) analysis is modeled using solid elements. Seismic mass is considered in the model in ordance with SRP Section 3.7.2 (USNRC, 2013a). Figure 3.4-1 and Figure 3.4-2 provide e-dimensional views of the structural model.

1.1 Design Response Spectra safe shutdown earthquake (SSE) ground motion is defined with a maximum ground eleration of 0.2 g and design response spectra in accordance with Regulatory Guide 1.60, ision 2, Design Response Spectra for Seismic Design of Nuclear Power Plants (USNRC, 4a).
sistent with SRP Section 3.7.2 (USNRC, 2013a), the location of the ground motion should be he ground surface. The competent material (material with a minimum shear wave velocity of 00 feet per second [ft./sec] [305 meters per second {m/s}]) is 7.5 ft. (2.3 m) below the ground ace for the site. Hence, the SSE response spectra are defined as an outcrop at a depth of ft. (2.3 m) below grade.
1.2 Design Time Histories SSI analysis and for generating in-structure response spectra, design acceleration time ories are required. Synthetic acceleration time histories are generated to envelop the design ponse spectra. Mutually orthogonal synthetic acceleration time histories are generated for h horizontal direction and one for the vertical direction. Each of these time histories meets the ign response spectra enveloping requirements consistent with Approach 2, Option 1 of SRP tion 3.7.1 (USNRC, 2014b). The specifics of each of these time histories are:
- Each synthetic time history has been generated starting with seed recorded earthquake time histories.
- The strong motion durations (Arias intensity to rise from 5 percent to 75 percent) of synthetic time histories are greater than a minimum of 6 seconds.
- The time history has a sufficiently small increment and sufficiently long duration. Records shall have a Nyquist frequency of at least 50 hertz (Hz) and a total duration of at least 20 seconds. The time step increment will be 0.005 seconds, which meets the Nyquist requirement for frequencies up to 100 Hz.
- Spectral acceleration at 5 percent damping is computed at a minimum of 100 points per frequency decade, uniformly spaced over the log frequency scale from 0.1 Hz to 50 Hz or the Nyquist frequency.
- Comparison of the response spectrum obtained from the synthetic time history with the target response spectrum shall be made at each frequency computed in the frequency range of interest.
- The computed 5 percent damped response spectrum of the acceleration time history shall not fall more than 10 percent below the target response spectrum at any one frequency and shall have no more than 9 adjacent frequency points falling below the target response spectrum.
- The computed 5 percent damped response spectrum of the artificial time history shall not exceed the target spectrum at any frequency by more than 30 percent in the frequency range of interest.
mparison of the response spectra obtained from the artificial acceleration time histories with target design response spectra illustrates that the enveloping criteria of SRP Section 3.7.1 NRC, 2014b) are satisfied. The seismic design parameters used in the seismic analysis of FSTR, including the artificial acceleration time histories, target design response spectra, and NE Medical Technologies 3.4-3 Rev. 5
1.3 Critical Damping Values ctural damping values for various structural elements used in the seismic analyses are vided in Section 1.1 of Regulatory Guide 1.61, Revision 1, Damping Values for Seismic ign of Nuclear Power Plants (USNRC, 2007d). Seismic SSI analysis of the FSTR is ormed in the program SASSI2010, Version 1.0, which performs the analysis in the frequency ain. The variations in damping are accounted for in the seismic SSI analysis through the plex frequency response analysis method which incorporates damping as an imaginary ponent in the stiffness matrix.

- The type of finite element used for modeling a structural system should depend on structural details, the purpose of analysis, and the theoretical formulation upon which the element is based. The mathematical discretization of the structure should consider the effect of element size, shape, and aspect ratio on solution accuracy.
- In developing a finite element model for dynamic response, it is necessary to consider that local regions of the structure, such as individual floor slabs or walls, may have fundamental vibration modes that can be excited by the dynamic seismic loading. These local vibration modes are represented in the dynamic response model, in order to ensure that the in-structure response spectra include the additional amplification.

2.2 Soil-Structure Interaction (SSI) Analysis SSI model provides structural responses for design basis level seismic loading of the main duction facility, including transfer functions, maximum seismic acceleration (zero period eleration [ZPA]), and in-structure response spectra (ISRS) (horizontal and vertical directions) various damping values. The SSI model is developed using the computer program SSI2010.
d elements are only used in the modelng of the excavated soil volume. No solid elements are d in the modeling of the building structure. Major structural elements of the main production lity, including walls, slabs, beams and columns, are modeled with appropriate mass and ness properties. Major openings within walls and slabs are included in the SSI model. The del uses thick shell elements to represent concrete slabs and walls, and beam elements to esent steel members, mostly comprising the truss components in the facility. Elements are deled at the geometric centerline of the structural member they represent with the following eptions:
- The below grade and mezzanine slabs are modeled at their actual top-of-slab elevation.
- Minor adjustments are made to the dimensions and locations of wall openings to maximize mesh regularity in the model.
- Roof truss locations are adjusted to align with the roof shell element mesh.
ddition to self-weight of the structure, floor loads and equipment loads are converted to mass included in the model. A mass equivalent to a 50 pounds per square foot (psf) floor load is ed to floor slabs to represent miscellaneous loads from minor equipment, piping, and eways. A portion of the loads are considered mass sources in the following manner according RP Section 3.7.2 (USNRC, 2013a):
- Dead Load 100 percent
- Live Load25 percent
- Snow Load.75 percent ddition, 100 percent of the hydrodynamic mass of the water in the IU cells and 100 percent of parked crane mass is included.
SSI analyses are performed separately on an equivalent linear-elastic basis for mean (best mate [BE]), upper bound (UB), and lower bound (LB) soil properties to represent potential ations in in-situ and backfill soil conditions around the building in accordance with SRP tion 3.7.2 (USNRC, 2013a). SSI analysis requires detailed input of the soil layers supporting structure. Strain dependent soil properties were determined from geotechnical investigations free field site response analysis. The free-field site response analysis is performed for the BE, and UB soil properties. In accordance with SRP Section 3.7.2, the UB and LB values of soil shear modulus, G, are obtained in terms of their BE through the equations shown below.
ations 3.4-2 and 3.4-3 are used to calculate the low strain properties for the LB and UB. The l soil properties are calculated from the SHAKE2000 program, version 3.5.

(Equation 3.4-3) ere, COV is the coefficient of variation. A COV of 0.5 is used because the site is
-investigated.
2.3 Combination of Earthquake Components rder to account for the responses of the structures subjected to the three directional (two zontal and the vertical) excitations, the maximum co-directional responses are combined g either the square root of the sum of the squares (SRSS) method or the 100-40-40 rule as cribed in Section 2.1 of Regulatory Guide 1.92, Revision 3, Combining Modal Responses and tial Components in Seismic Response Analysis (USNRC, 2012).
2.4 Seismic Analysis Results seismic loads are applied to the structural analysis model as described in Subsection 3.4.2.6 utilized to develop in-structure response spectra of the facility for use in sizing equipment components. Response spectra accelerations are output from SASSI at the 75 standard uencies between 0.2 Hz and 34 Hz as suggested by Regulatory Guide 1.122, Revision 1, elopment of Floor Design Response Spectra for Seismic Design of Floor-Supported ipment or Components (USNRC, 1978). In addition, response spectra accelerations are cified to be output at frequencies of 37 Hz, 40 Hz, 43 Hz, 46 Hz and 50Hz.
results of the seismic analysis demonstrate that the design of the FSTR meets the seismic uirements of SHINE Design Criterion 2.

Seismic excitation in each ction is considered using the 100-40-40 percent combination rule as specified in section 3.4.2.3 above.
lateral driving forces applicable to the seismic stability evaluation of the main production lity include active lateral soil force, static surcharge lateral soil force, dynamic surcharge ral soil, dynamic lateral soil force, and seismic lateral inertial force. The resistance for sliding ue to the static friction at the soil-basemat interface for sliding evaluation and passive lateral resistance. The self-weight of the structure is considered in the resistance to overturning cts.
seismic stability evaluation of the main production facility determined the minimum factor of ty against sliding to be 1.11 and the minimum factor of safety against overturning to be 1.99.
such, the main production facility is considered stable.

includes minimum live loads driven by occupancy and non-permanent loads caused by ipment or required during plant operations.
following categories encompass the live loads for the main production facility:
- A distributed live load of 125 psf (5.99 kPa) is used for areas designated as light manufacturing.
- A distributed live load of 250 psf (12.0 kPa) is used for areas designated as heavy manufacturing.

2.6.4.5 Earthquake Load amic analysis is conducted with a portion of the loads considered as mass sources in the wing manner according to SRP Section 3.7.2 (USNRC, 2013a):
- Dead Load 100 percent
- Miscellaneous Load.100 percent
- Live Load25 percent
- Snow Load.75 percent
- Parked Crane Load.100 percent
- Hydrodynamic Load100 percent thquake load is applied in a SAP2000 model (version 17.2) on an equivalent static basis. The ivalent static model represents the soil as dynamic springs, developed in accordance with CE 4-98 (ASCE, 2000). Maximum seismic acceleration at each node of the structure is ermined by SSI analysis using SASSI2010, as discussed in Subsection 3.4.2.2. Figures 3.4-3 ugh 3.4-6 show selected response spectra locations throughout the FSTR.
SAP2000 and SASSI2010 models are both three-dimensional models that represent the ctural elements with equivalent mass and stiffness properties. The lumped masses at each e of the SAP2000 analysis are multiplied by the peak accelerations determined from the SSI lysis to determine an equivalent static earthquake load at each node. The direction of load lication is iterated to obtain nine seismic force terms.
2.6.4.6 Crane Load building is evaluated for loads associated with two overhead bridge cranes, one servicing IU cell area and one servicing the RPF area.

2.6.4.7 Soil Pressure
-grade walls of the main production facility are designed to resist static lateral earth pressure s, compaction loads, static earth pressure, dynamic surcharge loads, and elastic dynamic pressure loads. Static earth pressure consists of at-rest, active, and passive soil pressure s, which are applied as required to ensure the stability of the building.
NE Medical Technologies 3.4-10 Rev. 5
hydrostatic loading is calculated based on the actual dimensions of the IU cells and applied e model as lateral hydrostatic pressure on the walls and vertical hydrostatic pressure on the om slabs.
hydrodynamic loading is applied to the model by considering hydrodynamic masses rigidly ched to the IU cells in accordance with Section 3.1.6.3 of ASCE 4-98 (ASCE, 2000) and pter 6 of TID-7024, Nuclear Reactors and Earthquakes (AEC, 1963). The provisions, as ined in the referenced documents, require that the impulsive and convective masses be lied to the model to capture the dynamic effects due to seismic motion.
2.6.4.9 Tornado Load tornado load is based on a tornado wind speed of 230 mph (370 kph) and a tornado missile ctrum as described in Table 2 of Regulatory Guide 1.76 (USNRC, 2007a). The tornado load, is further defined by the following combinations:
W t = Wp (Equation 3.4-7)
Wt = Ww + 0.5Wp (Equation 3.4-8)
Wt = Ww + 0.5Wp + Wm (Equation 3.4-9) ere:
Wp = load from tornado atmospheric pressure change Ww = load from tornado wind Wm = load from tornado missile impact 2.6.4.10 Accidental Eccentricity equired by Section 3.1.1(e) of ASCE 4-98, Seismic Analysis of Safety-Related Nuclear ctures and Commentary (ASCE, 2000), the structure is evaluated for a torsional moment due ccidental eccentricity. The torsional moment is taken equal to the story shear at the elevation in the direction of interest times a moment arm equal to 5 percent of the building dimension.
torsional moment is distributed to the building shear walls based on the relative rigidity of the s in plane. The loads are applied statically and account for variability in the load direction.
2.6.5 Structural Analysis Model ree-dimensional finite element model of the main production facility structure was created g the computer program SAP2000 (version 17.2) to represent the mass and stiffness of the or structural elements, equipment, and components of the FSTR.

- Roof truss locations are adjusted to align with the roof shell element mesh.
adjustments described above are intended to maintain mesh regularity to the extent sible.
2.6.6 Structural Analysis Results crete walls and slabs in the main production facility are designed for axial, flexural, and shear s per provisions of ACI 349-13 (ACI, 2014) considering all applicable design basis load binations. Walls and slabs are modeled in SAP2000 using shell elements. To determine the itudinal and transverse reinforcement required within a wall or slab, the design is performed an element basis. Using resultant forces obtained from SAP2000 model data, the element is igned as a reinforced concrete section per ACI 349-13 (ACI, 2014). The required area of steel etermined for combined axial and flexural loads, in-plane shear loads, and out-of-plane shear

3 SEISMIC CLASSIFICATION AND QUALIFICATION subsection discusses the methods by which the SHINE facility SSCs are classified and lified to ensure functional integrity.
3.1 Seismic Classification ility SSCs, including their foundations and supports, that must perform safety function(s) after SSE are designated as Seismic Category I. Safety-related SSCs are classified as Seismic egory I.
Cs that are co-located with a Seismic Category I SSC and must maintain structural integrity in event of an SSE to prevent unacceptable interactions with a Seismic Category I SSC, but are required to remain functional, are designated as Seismic Category II.
seismic classifications of SSCs are shown in Table 3.4-1.
3.2 Seismic Qualification eneral, one of the following four methods of seismically qualifying the SSCs is chosen based n the characteristics and complexities of the subsystem:
- Dynamic analysis.
- Testing.
- Comparison with existing databases.
- A combination of analysis and testing.
methods to be used for qualification are stated below. These methods will depend on the of equipment and supporting structure. The following defines some of the possible cases associated analytical methods which may be used in each case.
NE Medical Technologies 3.4-12 Rev. 5
tems, quantitative evaluation criteria are applied only to the most seismically vulnerable ions of these systems.
3.2.1 Qualification by Analytical Methods lytical calculations may be used as a qualification method when maintaining the structural grity is an assurance for the safety function. This method can be used for equipment and ng systems when expected response to the earthquake excitations can be characterized as ar or simple non-linear behavior (e.g., piping, skids, and large equipment).
S from Subsection 3.4.2.2 are used in the response spectrum analysis of piping and ipment. These response spectra are used to determine the seismic requirements at the ponent mounting locations for qualification purposes and for piping subsystem dynamic lysis.
tic Analysis equipment, as well as its support, can be considered rigid, and may be analyzed by static lysis, if it can be shown that its fundamental natural frequency does not fall in the frequency ge below the high frequency asymptote (ZPA) of the required response spectrum (RRS).
rigid equipment supported by a rigid structure, the equipment motion shall be the same as floor motion without amplification. The horizontal and vertical dynamic accelerations shall be n as the ZPA from the applicable response spectrum. These acceleration values are used to orm a static analysis. In this case, the dynamic forces are determined by multiplying the ss of the subassembly or parts of the equipment by the ZPA of the RRS. These forces should applied through the center of gravity of the subassembly or the part of the equipment.
stresses resulting from each force (in each of the three directions) should be combined by an ropriate combination method to yield the dynamic stresses. The dynamic deflections lections due to dynamic loads) may be calculated in the same manner. These dynamic sses and deflections are combined with stresses and deflections from other loads per the combinations defined in the applicable design codes.
plified Dynamic Analysis mplified dynamic analysis may be performed in cases where the equipment and support tems natural frequency falls in the frequency range below the high frequency asymptote A) of the applicable RRS. This is similar to the static analysis described above but requires g different values for the accelerations. The accelerations to be used are obtained from the ropriate ISRS curves at each natural frequency in the frequency range of interest. If the uency information is not available, the simplified dynamic analysis (sometimes referred to as equivalent static analysis) is performed using 1.5 times the maximum peak of the applicable r response spectra. Once the dynamic forces are determined using the 1.5 times the peak eleration values from the RRS, stresses and deformations may be computed following the e procedures used for static analysis.
NE Medical Technologies 3.4-13 Rev. 5
en acceptable justification for static or simplified dynamic analysis cannot be provided, a ailed dynamic analysis is performed. A mathematical model may be constructed to represent dynamic behavior of the equipment. A finite element model may be constructed and analyzed g the response spectrum modal analysis or time-history analysis. The maximum inertia es, at each mass point, from each mode, are applied at that point to calculate the modal ctions (forces and moments) and modal deformations (translations and rotations). The ous modal contributions are combined by an appropriate combination method. Closely ced modes are combined by using an approach from Regulatory Guide 1.92 (USNRC, 2012).
stresses and deflections resulting from each of the three directions are combined to obtain dynamic stresses and deflections. These dynamic stresses and deflections are combined stresses and deflections from other loads per the load combinations defined in the licable design codes.
3.2.2 Qualification by Tests smic qualification by testing is the preferred method of qualification for complex equipment suitable for analysis, and for equipment required to perform an active function (e.g., valves instrumentation). Qualification by testing may be performed using applicable procedures cified by Institute of Electrical and Electronics Engineers (IEEE) and/or ASME qualification of ve mechanical equipment (QME) standards.
vibration inputs for the seismic tests are the response spectra or Required Input Motion ical for line-mounted equipment) at the mounting location of the equipment. ISRS are used to elop Test Response Spectra for testing.
test samples shall be mounted to simulate the recommended service mounting. If this not be done, the effect of the actual supporting structure shall be considered in determination he input motion. The project specification will state the expected (or calculated) piping nozzle ction loads on the equipment which shall be used in the qualification. Any other loads that y act on the component (mechanical, electrical, or instrument) during the postulated dynamic nt must be simulated during the test, unless the supporting test (or calculations) shows that are insignificant.
he completion of the tests, inspection shall be made by the test conductor to assure that no ctural damage has occurred. Sufficient monitoring devices shall be used to evaluate the ormance of the active components during the tests. For acceptability, the components shall onstrate their ability to perform their intended safety functions when subjected to all licable loads.
3.2.3 Comparison with Existing Databases S are used to develop RRS for comparison with existing response from a database. The didate equipment must be similar to equipment in the existing seismic experience databases.
NE Medical Technologies 3.4-14 Rev. 5
ed on the available information, component complexity, and functional requirements, the ve mentioned analytical and test methods may be combined in various sequence and content chieve seismic qualification of the subject components.
4 SEISMIC INSTRUMENTATION smic instrumentation is not required under Section IV(a)(4) of Appendix S to 10 CFR 50 or tion VI(a)(3) of Appendix A to 10 CFR 100 because the main production facility is not a lear power plant. However, the facility has nonsafety-related seismic instrumentation to ord accelerations experienced at the site during a seismic event.
seismic instrumentation establishes the acceptability of continued operation of the plant wing a seismic event. This system provides acceleration time histories or response spectra erienced at the facility to assist in verifying that safety-related SSCs at the main production lity can continue to perform their safety functions.
smic monitoring is performed by the process integrated control system (PICS), which is cribed in Section 7.3. Indication of a seismic event results in an alarm in the facility control m.
5 SEISMIC ENVELOPE DESIGN FOR EXTERNAL HAZARDS 5.1 AIRCRAFT IMPACT ANALYSIS safety-related structures at the SHINE facility are evaluated for aircraft impact loading ulting from small aircraft which frequent the Southern Wisconsin Regional Airport (SWRA).
analysis consists of a global impact response analysis and a local impact response analysis.
global impact response analysis is performed using the energy balance method, consistent U.S. Department of Energy (DOE) Standard DOE-STD-3014-2006 (DOE, 2006). The missible ductility limit for reinforced concrete elements is in accordance with Appendix F of 349-13 (ACI, 2014). The permissible ductility limit for truss members is determined from pter NB of ANSI/AISC N690-12 (ANSI/AISC, 2012). The calculated values are then used to ate the appropriate elastic or elastic-plastic load deflection curves. From these curves, the ilable energy absorption capacity of the structure at the critical impact locations is ermined. The Challenger 605 was selected as the critical aircraft for the global impact lysis based on a study of the airport operations data. The Challenger 605 is evaluated as a ign basis aircraft impact. The probabilistic distributions of horizontal and vertical velocity of act are determined from Attachment E of Lawrence Livermore National oratory UCRL-ID-123577 (UCRL, 1997) to correspond to 99.5 percent of impact velocity bability distribution.
h wall that protects safety-related equipment was evaluated for perpendicular impacts at the ter of the wall panel and at critical locations near the edge of the wall panel. Each roof that ects safety-related equipment was evaluated for perpendicular impacts near the end of the truss, at the center of the roof truss, at the center of the roof panel between trusses or walls.
evaluation of the roof slab for horizontal seismic loading bounds any aircraft impact scenario NE Medical Technologies 3.4-15 Rev. 5
local response evaluation was conducted using empirical equations in accordance with E-STD-3014-2006 (DOE, 2006). The structure was shown to resist scabbing and perforation.
unching shear failure was not postulated because all sections are shown to have a thickness percent greater than the thickness required to prevent perforation, based on Appendix F of 349-13 (ACI, 2014). Scabbing and perforation thickness requirement was calculated using E-STD-3014-2006 (DOE, 2006).
ause engine diameter and engine weight are both critical for the local evaluation, the local act evaluation was performed for the Hawker 400 as well as the Challenger 605 aircraft. The llenger 605 and Hawker 400 are evaluated as design basis aircraft impacts.
evaluate the capability of the structure to withstand impact from an aircraft, each wall that is ject to potential impact from an aircraft missile is evaluated. Figure 3.4-7 shows the openings e building which are evaluated as missile barriers.
design basis aircraft impacts have been evaluated against the acceptance criteria of 349-13 (ACI, 2014) for concrete and ANSI/AISC N690-12 (ANSI/AISC, 2012) for steel and it been demonstrated that all components of the FSTR structure that are relied upon to provide act protection have adequate energy absorption capacity to perform their design basis tion.
5.2 EXPLOSION HAZARDS ause the SHINE facility is not licensed as an operating nuclear reactor, explosions postulated result of the design basis threat as defined in Regulatory Guide 5.69, Guidance for the lication of Radiological Sabotage Design-Basis Threat in the Design, Development and lementation of a Physical Security Program that Meets 10 CFR 73.55 Requirements NRC, 2007e), are not considered. However, accidental explosions due to transportation or age of hazardous materials outside the facility and accidental explosions due to chemical ctions inside the facility are assessed.
maximum overpressure at any safety-related area of the facility from any credible external rce is discussed in Subsection 2.2.3). The seismic area is protected by outer walls and roofs sisting of reinforced concrete robust enough to withstand credible external explosions as ned in Regulatory Guide 1.91, Revision 2, Evaluations of Explosions Postulated to Occur at rby Facilities and on Transportation Routes Near Nuclear Power Plants (USNRC, 2013c).

design of the SHINE facility and systems is based on defense-in-depth practices. Defense-epth practices means a design philosophy, applied from the outset and through completion of design, that is based on providing successive levels of protection such that health and safety not wholly dependent upon any single element of the design, construction, maintenance, or ration of the facility. The net effect of incorporating defense-in-depth practices is a servatively designed facility and systems that exhibit greater tolerance to failures and rnal challenges.
SHINE facility and system design incorporates a preference for engineered controls over inistrative controls, independence to avoid common mode failures, and incorporates other ures that enhance safety by reducing challenges to safety-related components and systems.
sical separation and electrical isolation are used to maintain the independence of safety-ted control circuits and equipment among redundant safety divisions or with nonsafety tems so that the safety functions required during and following design basis events can be omplished.
undancy is also incorporated into system designs. Two divisions of safety-related protection tems and two divisions of safety-related emergency power are provided for active engineered trols that depend on control and/or continued power to perform their safety functions. Active ineered safety-related SSCs requiring control or power may be reduced to a single division n redundancy of the function is provided by other means (e.g., when a check valve is used in bination with an automatically actuated isolation valve).
design bases for the SSCs of the SHINE facility are described in detail throughout the FSAR.
FSAR sections where SSCs are described also provide information that is used in the nical specifications. This includes limiting conditions for operation, setpoints, design ures, and means for accomplishing surveillances. In addition, these FSAR sections also sent information that is applicable to, and may be referenced by, the technical specification es.
NE Medical Technologies 3.5-1 Rev. 0
nitrogen purge system (N2PS) structure is a safety-related structure which contains a ion of the N2PS. The N2PS structure is located adjacent to the main production facility, as wn in Figure 1.3-3.
1 METEOROLOGICAL DAMAGE N2PS structure is designed to withstand the same potential meteorological damage as cribed in Section 3.2 for the main production facility structure (FSTR). The Regulatory des, codes, and standards associated with the FSTR analysis described in Section 3.2 are licable to the N2PS structure. Rain loading is not considered in the structural design of the S structure as the sloped roof does not result in rain accumulation. As a result of the lack of accumulation, load due to ice is anticipated to be minimal and is enveloped by the design w load. The N2PS structure is categorized as an enclosed building and, as a result, both rnal and internal pressures are applied to the structure when considering wind loading.
d, tornado, and snow loading is applied to the N2PS structure as described in Section 3.2 for FSTR with the following exceptions:
- The applied N2PS structure uniform snow load of 60 pounds per square foot (psf) is conservative considering 30 psf ground snow load with 1.2 importance factor for the 100-years mean recurrence interval.
- The N2PS structure tornado load includes tornado generated missile load, tornado wind load, and differential pressure consistent with the methodology described in Section 3.2 for the FSTR; however, normal wind load is not considered because the tornado wind load bounds the normal wind load.
- Due to the proximity of the N2PS structure to the main production facility, tornado missile protection is not required for penetrations in the N2PS structure on the west wall facing the FSTR as the FSTR shields that wall from tornado generated missiles.
2 WATER DAMAGE 2.1 External Flooding main production facility design basis precipitation, flood levels, and ground water levels, vided in Section 3.3, are also applicable to the N2PS structure, and are as follows:
- Design basis flood level: 50 feet (ft.) (15.2 meters [m]) below grade.
- Design basis precipitation level: at grade.
- Maximum ground water level: 50 ft. (15.2 m) below grade.
Subsection 2.4.2.3, a local probable maximum precipitation (PMP) event creates a water l about level with grade. The N2PS structure floor is raised at least 4 inches above grade; efore, water will not infiltrate the door openings in the case of a local PMP event.
Subsection 2.4.3, a local probable maximum flood (PMF) event creates a water level roximately 50 ft. (15.2 m) below grade. The lowest point in the N2PS structure is above de; therefore, flooding does not cause any structural loading in the case of a local PMF event.
NE Medical Technologies 3.6-1 Rev. 0
re is no risk of internal flooding as there are no water sources internal to the N2PS structure.
3 SEISMIC DAMAGE N2PS structure seismic analysis is based on the equivalent static load method and uses the mic analysis of the FSTR described in Section 3.4. The N2PS structure seismic loads are ulated using the in-structure-response-spectra (ISRS) for FSTR grade level with an plification factor of 1.5. The N2PS structure seismic analysis can be realistically represented simple model, and the equivalent static load method with a 1.5 amplification factor produces servative results in terms of responses. The N2PS structure has a footprint of approximately
- t. by 13 ft., and is located adjacent to the FSTR, which has an approximate footprint of 212 ft.
58 ft. The N2PS structure seismic analysis, based on the equivalent static load method, servatively accounts for relative motion. Comparing the two structures and locations, the S structure response will be driven by the FSTR response and the N2PS structure will not ct the FSTR response. The use of FSTR grade level ISRS at N2PS structure grade level, with amplification factor of 1.5, conservatively accounts for the structure-soil-structure interaction SI) effects of the FSTR structure on the N2PS structure.
