NWMI interpreted NUREG-1537, Guidelines for Preparing and jReviewing Applications for the Licensing of Non-Power Reactors: Plan and 1Acceptance Criteria, Part 2, Chapter 13, as augmented by the Interun Staff Gui.dance (ISG) (NRC, ]2012), as requiring.an analysis consistent with both 10 CFR 70.61, "Performance Requirements," and lwith the MHA approach. Additionally, the PSAR combined the two in its approach to the MHA, jproducing an analysis inconsistent with the intended requirements of an MHA analysis. t fThe accident analyses in the final safety analysis report (FSAR); as part of the Operating License !Application, will be consistent with the requirements of 10 CFR 70.61. As stated in Chapter 13b, !"Radioisotope Production Facility Accident Analyses,'.' of the ISG Augmenting NUREG-1537, Part 1: I . l NRC staff has determined that the use of Integrated Safety Analysis methodologies as described in 10 CFR Part 70 Subpart Hand NUREG-1520, application of the radiological and chemical consequence and likelihood criteria contained in the performance requirements of 10 CFR 70. 61, designation of items relied on for safety, and establishment of management measures, are acceptable ways of demonstrating adequate safety for the medical isotopes production facility. fThe accident analyses in the PSAR are based on (1) use of integrated safety analysis (ISA) !methodologies, as described in 10 CFR 70 Subpart Hand NUREG-1520, Standard Review Plan for the !Review of a License Application for a Fuel Cycle Facility, (2) application of the radiological and !chemical consequence and likelihood criteria contained in the performance requirements of 10 CFR l?0.61, (3) designation of items relied on for safety (IROFS), and (4) establishment of management jmeasures to demonstrate adequate safety. \The ISA includes a systematic analysis and discussion of credible accidents for determining the limiting ievents for several accident categories. The limiting event in each category is analyzed quantitatively to !determine consequences. Radiological accident consequences, as mitigated by structures, systems, and jcomponents (SSC) and administrative safety measures, are evaluated against the performance !requirements of 10 CFR 70.61. The safety measures are designated as IROFS. 2 of96 NWMl-2016-RAl-004, Rev. 0 '-Request for Additional Information !Based on the response to RAI G-3, PSAR.Section 13.2, "Analysis ofAccidents with Radiological and !Criticality Safety Consequences" Will be revised and the MHA discussion in PSAR Section 13.2.1 will \be deleted. f'G . '.itiidili !SSCs will be designed to protect against both high and immediate consequences. PSAR Section 3.5.1.3.1 jdescribed both the high and the immediate consequence performance requirements from 10 CFR 70.61. jTo eliminate confusion and ensure completeness, these bullets were removed from PSAR .Section 3.5.1.3 j(see Attachment A), and the 10 CFR 70.61 performance requirements are referenced. 3 of96 NWMl-2016-RAl-004, Rev. 0 CHAPTER 2.0 -SITE CHARACTERISTICS No. Request for additional information if;,;; 4.

The three airports include:
• Columbia Regional Airport (public) located approximately 10.4 km (6.5 mi) south of the RPF site 1
• Cedar Creek Airport (private) located approximately 10.6 km (6.6 mi) northeast of the RPF site Sugar Branch Airport (private) located approximately 15.6 km (9.7 mi) northwest of the RPF site iTuese airports are identified in PSAR Chapter 2.0, Figure 2-30, of the Construction Permit Application. :The nearest airport to the RPF is the Columbia Regional Airport, which is used by commercial and 'privately owned aircraft. The airport is situated on approximately 0.532 ha (1,314 acres) and is owned :and operated by the City of Columbia. This airport is the only public use airport located in Boone ;county, Missouri, for which records are kept. For the 12-month period ending October 31, 2013, the 'airport had 16,610 aircraft operations for an average of 26 flights per day, including: ' . l
• 81 percent general aviation 16 percent air taxi 2 percent military 1 percent air carrier :Cedar Creek airport is a private turf landing strip approximately 10.6 km (6.6 mi) northeast of the RPF ; '.site. The facility houses two private single engine aircraft. The specific number of flights to and from the i ;facility is not available. The Sugar Branch airport is a private, turf landing strip approximately 15.6 km (9.7 mi) northwest of the ;RPF site. The facility houses one single engine aircraft. The specific number of flights to and from the :facility are not available. 'Three helicopter ports are located within 16 km ( 10 mi) of the RPF site and support hospital operations, ,including:
• University of Missouri Hospitals and Clinics heliport located 6 km (3. 7 mi) northwest
• University of Missouri (MU) heliport located 6 km (3.7 mi) northwest Boone Hospital Center heliport located 6.3 km (3.9 mi) northwest. 4 of96 NWMl-2016-RAl-004, Rev. 0 .. *:.* * ".. .. NqrtrnwuT,MflMCAl tsotOPfS !No operations data are available for these heliports. ! 1Based on NUREG-1537, sites located between 8 km (5 mi) and 16 km (10 mi) from an existing or . \projected commercial or military airport with more than approximately 200 d2 (where dis the distance in ; !kilometers from the airport to the RPF site) commercial or military aircraft movements per year, the )probability of aircraft accidents is considered less than an order of magnitude of 10-7 per year. * !Tue number of operations at the Cedar Creek and Sugar Branch airports are not available. However, daily) 1operations were assumed based on the aircraft housed, including two operations per day from Cedar '. iCreek (730 operations/year) and one operation per day from Sugar Branch (365 operations/year). Based '. jon the results presented in Table 1, all three airports are under the 200 d2 limits.
• i Airport Table 1. 200 D2 Limits Distance km (mi) Flights per year i is the distance in from the airport to the .RPF site (200. x qistance, squared) ..... 200 d2 limitsa !Based on this requirement, none of these airports needs to be further evaluated. The guidance also jrequires that special consideration be given to facilities sited within the trajectory of a runway of any ;airport. The RPF site is not located within a trajectory of a runway of the airport. ' iBecause the three heliports are closer than 8 km (5 mi) to the RPF site, the frequency of an aircraft jcrashing into the site needs to be evaluated. NUREG-0800, Standard Review Plan for the Review of iSafety Analysis Reports for Nuclear Power Plants, Subsection 3 .5 .1. 6, provides a methodology for , !determining the probability of an aircraft crash into a facility from airways. However, the approach requires : !knowledge of the number of flights per year along the airway. Because this information is not available 1for the flight paths near the RPF, DOE-STD-3014-2006, Accident Analysis for Aircraft Crash into !Hazardous Facilities, was used to determine the frequency of crashes. The following equation is used. !Where: : I Fh N Ph fh(x,y) Fh = Nh x Ph x fh(x,y) x Ah Crash impact frequency Flight per year Probability of a crash Probability, given a crash, that the crash occurs in a l-mi2 area surrounding the facility = Effective plant area. \The effective area for an aircraft was determined by two components: the aircraft crashing into the !facility either by skidding or by flying directly into it. The effective area was calculated based on an laircraft skidding or flying into the facility in the direction that produces the largest area (i.e., crashing in a; jdirection perpendicular to the largest diagonal of the building). , ' iThe following formula was used to calculating the skid and fly in areas of an aircraft crashing into the !facility. , \Where: , (2 xL x W x WS) Ar = (WS + R) x H x cot</J + R + L x W 5 of 96 L ..

NWMl-2016-RAl-004, Rev. 0 '.DOE-STD-3014-2006 notes that in calculating an effective area, the analyst needs to be cognizant of the ;"critical areas" of the facility. The critical areas are locations in a facility that contain hazardous material and/or locations that, once impacted by a crash, can lead to cascading failures (e.g., a fire, collapse, '.and/or explosion that would impact the hazardous material). The critical areas of the RPF are considered , *to be the hot cell and waste management areas. * *The critical areas dimensions are estimated at 30.5 x 24 meters (m) (100 x 80 feet [ft]), which provides a ; diagonal (R) of39 m (128 ft). The facility height (H) of22.9 m (75 ft) was used. DOE-STD-3014-2006 l . provides estimates for aircraft wingspan, mean of the cotangent of the aircraft impact angle, and skid .distance for five different aircraft types. For helicopters, the cot<l> value is 0.58 and the skid length is 'typically assumed to be 0. The effective area is calculated in Table 2. Aircraft Helicopter : Wing spana ws (ft) 50 Table 2. Affective Area for Helicopter cot<l>a 0.58 Skid distancea s (ft) 0 Effective plant area Ah (mi2) 0.00079 a DOE-STD-3014-2006, Accident Analysis for Aircraft Crash into Hazardous Facilities, U.S. Department of Energy, Washington, D.C., 1996 (R2006). For a helicopter, fh(x,y) is estimated based on half the average length of a flight with the lateral :variations in crash locations assumed to be one-quarter mile on the average from the centerline of the *flight path or 2/L. The probability Ph (2.50E-05) is taken from DOE-STD-3014-2006, Appendix B :Table B-1. The total number of flights from the three helipads are estimated at 1,825 per year. A ; !conservation estimate is that 5 percent of these helicopters overfly the facility. In addition, a conservative i :estimate of total flight path is the distance to the closest helipad or 6 km (3.7 mi). I !Based on these assumptions, the helicopter impact frequency is calculated as follows: 2 Fh = 91 x 2.SE-05 x 3_7 x 7.9£-04 Fh = 9.7E-o7 The calculated crash impact frequency from the heliport is less than the requirement ofNUREG-0800 of f '.being within an order of magnitude of 10-7 per year. Therefore, no further analysis is required. This ; 'information will be added to PSAR Section 2.2.2. 6 of 96 NWMl-2016-RAl-004, Rev. 0 -Request for additional information iPSAR Section 2.2.2.1 had a typographical error. 10.4 km (6.5 mi) is the correct distance from the !Columbia Regional Airport to the RPF site, based on Google Earth measurements, and 10.4 km (6.5 mi) \is the distance used in the associated calculations.

• f .. iSection 5.1 of the validation report (NWMI-2014-RPT-006), including Figures 5, 6, and 7, evaluates :trends in important validation parameters. The calculation methodology should have a method bias that :has neither dependence on a characteristic nor is a smooth function of a parameter. If a trend in a parameter exists, the bias will vary as a function of that trend over the parameter range. If no trend in the ;Parameter exists, then the bias will be constant over the parameter range . . Figure 5 groups individual experiments into sets that correspond to common moderators that include .water, graphite, carbon fluoride (CF2), hydrogen bound in uranium trihydride (UH3), and no moderator. 'When the calculation results for these experiment sets are graphed, some of the experimental results lie ;below akeffof 1.0. Figure 5 does not represent a bias calculation; it is an evaluation to determine if a ;trend exists in the moderator parameter that would suggest the method bias (calculated in Section 5.3 of -the validation report) has a dependence on moderation. In the Section 5.1.5 discussion of conclusions ,regarding the trending evaluation depicted in Figure 5, rather than stating the evaluation demonstrates no l ;significant bias with the various moderators, the statement should read, "the evaluation demonstrates no :significant trend with respect to moderation that would influence the method bias." *Similarly, for Figure 6, the intent is to determine if a trend exists in the reflector parameter that would : suggest the method bias (calculated in Section 5 .3) has a dependence on reflection. The Section 5 .1. 6 1discussion will be modified to "the evaluation demonstrates no significant trend with respect to reflection! 'that would influence the method bias." * :For Figure 7, the intent is to determine if a trend exists with respect to chemical form that would suggest 'the method bias has a dependence on chemical form. Section 5.1.7 will be modified to "the evaluation :demonstrates no significant trend with respect to chemical form that would influence the method bias." 'The method bias is developed in Section 5.3, and all of the experiment sets included in Figures 5 through! 7 are evaluated there for the method bias calculation. * ,* *.

Zones I, Il, and ID will potentially be ; contaminated areas, with Zone Ill being the cleanest of the potentially contaminated areas, and each isubsequent zone being more contaminated and having lower pressures, as shown below: Pzone I <PZone II< Pzone III i Details of the facility ventilation system provided in PSAR Section 9 .1.2 were intended to meet this (philosophy. PSAR Section 3.1 provides the codes and standards that the ventilation system will be !designed to. I !The RPF preliminary design of ventilation and containment systems was developed to ensure the !sufficiency of the principal design criteria, design bases, general arrangement, and approximate !dimensions sufficient to provide reasonable assurance that the final design will conform to the design ;basis. The final facility design of the ventilation and confinement system will be described in the FSAR ias part of the Operating License Application. *--*:-"**-*-, :..--., *. -.:.* *. *-<*/.._._, *-* ',-<.: __ :.,.:;; .-C';'.""'"""-:-4 )'.* RAI 11.'.3-J;*i*S'.ecqon 20.1701' ojl'O C:F'RPart 20 states thai the shall'itse, to. the extent pfaci:ical, prqcess" .; \ , , * , * " _ * * * * * , .' ** *, ",*. * > ' ' ' ' '" , r '.

The basis for the :difference in QL-1 and QL-2 is a graded approach to quality, by which the level of analysis, :documentation, and actions necessary to comply with a requirement is commensurate with the safety :significance. The graded approach permits the implementing organization to focus resources on those that are deemed, by qualitative analysis, to reduce the associated risks and hazards.

A graded approach! !permits the implementing organization to focus resources on those activities that are deemed, by ! 1qualitative analysis, to reduce the associated risks and hazards. Activities and tasks are performed in accordance with the quality level definitions.

• Quality Level 1 will be applied to IROFS (SSCs and activities). IROFS are QL-1 items in which ; failure or malfunction could directly result in a condition that adversely affects workers, the public, l and/or environment, as described in 10 CFR 70.61. Quality Level 2 will be applied to safety SSCs that are non-QL-1 SSCs. Some of the required characteristics may be examined less rigorously than for QL-1 items. Quality Level 3 items include those items that are not classified as QL-1 or QL-2. QL-3 items are controlled in accordance with standard commercial practices. 78 of96

A rupture disk vent path has been included in current !equipment descriptions as the feature that mitigates a potential accident resulting in exothermic reactions 1 \within the ion exchange column. The research and development results will either:
• I 1. Confirm that a pressure relief system is feasible to design for an ion exchange column operating at approximately 45 lb/in2 gauge and the uranium separation process approach will continue, or 2. Require a design change to the system or implementation of additional controls/process parameters to reduce the likelihood of a reaction or change of separation technology. jl ,.* . .; * * "7-,.,;.. -::;" = */-*.:t* '"< .. . ***";-: ....

Procedures will be developed to \place equipment/plant conditions in a proper configuration for outages, including surveillance and imonitoring activities. The radioactive inventory after a one-month shutdown is only 5 percent of the lincoming inventory of eight MURR targets 8 hours after end of irradiation.

• NORTHWESTMEDlCAl.ISOTOPES NWMl-2015-021, Rev. OA Chapter 3.0 -Design of Structures, Systems and Components 3.5 SYSTEMS AND COMPONENTS Certain systems and components of the RPF are considered important to safety because they perform safety functions during normal operations or are required to prevent or mitigate the consequences of abnormal operational transients or accidents. This section summarizes the design basis for design, construction, and operating characteristics of safety-related SSCs of the RPF. 3.5.1 General Design Basis Information 3.5.1.1 Classification of Systems and Components Important to Safety The RPF systems and components will be classified according to their importance to safety, quality levels, and seismic class. The guidance used in developing these classifications during preliminary design with the support of regulatory guidance reviews, hazards and operability analysis, accident analysis, integrated safety analysis, and national consensus code requirements is presented below. The RPF systems identified in Table 3-1 and their associated subsystems and components are discussed in the subsections that follow. 3.5.1.2 Classification Definitions The definitions used in the classification of SSCs include the following. In accordance with 10 CFR 50 .2, "Definitions," design basis refers to information that identifies the specific functions to be performed by an SSC of a facility and the specific values or ranges of values chosen for controlling parameters as reference bounds for design. These values may be: *
• Restraints derived from generally accepted state-of-the-art practices for achieving functional goals Requirements derived from analysis (e.g., calculation, experiments) of the effects of a postulated accident for which a SSC must meet its functional goals These reference bounds are to include the bounding conditions under which SSCs must perform design basis functions and may be derived from normal operation or any accident or events for which SS Cs are required to function, including anticipated operational occurrences, design basis accidents, external events, natural phenomena, and other events specifically addressed in the regulations. Safety-related is a classification applied to items relied on to remain functional during or following a design basis event (DBE) to ensure the: * *
• Integrity of the facility infrastructure Capability to shut down the facility and maintain it in a safe shutdown condition Capability to prevent or mitigate the consequences of accidents that could result in potential site exposures comparable to the applicable guideline exposures set forth in 10 CFR 70.61, "Performance Requirements," as applicable Design basis accident is a postulated accident that a nuclear facility must be designed and built to withstand, without loss to the SSCs necessary to ensure public health and safety. Design basis event (DBE) is an event that is a condition of normal operation (including anticipated operational occurrences), a design basis accident, an external event, or natural phenomena for which the facility must be designed so that the safety-related functions are achievable. 3-43

• NOflTHVJESTMEDICALISOTOPES NWMl-2015-021, Rev. OA Chapter 3.0 -Design of Structures, Systems and Components Design basis accidents and transients are those DBEs that are accidents and transients and are postulated in the safety analyses. The design basis accidents and transients are used in the design of the facility to establish acceptable performance requirements for SSCs. Single failure is considered a random failure and can include an initiating event (e.g., component failure, natural phenomenon, external man-made hazard) or consequential failures. Mechanical, instrumentation, and electrical systems and components required to perform their intended safety function in the event of a single failure are designed to include sufficient redundancy and independence. This type of design verifies that a single failure of any active component does not result in a loss of the capability of the system to perform its safety functions. Mechanical, instrumentation, and electrical systems and components are designed to ensure that a single failure, in conjunction with an initiating event, does not result in the loss of the RPF's ability to perform its intended safety function. Design techniques such as physical separation, functional diversity, diversity in component design, and principles of operation, will be used to the extent necessary to protect against a single failure. An initiating event is a single occurrence, including its consequential effects, that places the RPF (or some portion) in an abnormal condition. An initiating event and its resulting consequences are not considered a single failure. Active components are devices characterized by an expected significant change of state or discernible mechanical motion in response to an imposed demand on the system or operation requirements (e.g., switches, circuit breakers, relays, valves, pressure switches, motors, dampers, pumps, and analog meters). An active component failure is a failure of the component to complete its intended safety function(s) on demand. Passive components are devices characterized by an expected negligible change of state or negligible mechanical motion in response to an imposed design basis load demand on the system. Defense-in-depth is an approach to designing and operating nuclear facilities that prevents and mitigates accidents that release radiation or hazardous material through the creation of multiple independent and redundant layers of defense to compensate for potential human and mechanical failures so that no single layer, no matter how robust, is exclusively relied on. Defense-in-depth includes the use of access controls, physical barriers, redundant and diverse key safety functions, and emergency response measures. The RPF structure and system designs are based on defense-in-depth practices. The RPF design incorporates: * *
• Preference for engineered controls over administrative controls Independence to avoid common mode failures Other features that enhance safety by reducing challenges to safety-related components and systems Safety-related systems and components identified in this section are described in Chapters 4.0; 5.0, "Coolant Systems;" 6.0; 7.0; 8.0, Electrical Power Systems;" and 9.0, "Auxiliary Systems," as appropriate. 3.5.1.3 Nuclear Safety Classifications for Structures, Systems, and Components SSCs in the RPF are classified as safety-related and non-safety-related. The safety-related SSCs include IROFS to meet the performance requirement of 10 CFR 70.61 and other safety related SSCs to meet the requirements of 10 CFR 20. The purpose of this section is to classify SSCs according to the safety function being performed. 3-44

The classification system provides a recognizable means of identifying the extent to which SS Cs are related to safety-related and seismic requirements, including ANS nuclear safety classifications, NRC quality groups, ASME Code Section III classifications, seismic categories, and other applicable industry standards, as shown in Table 3-T. Quality assurance (QA) requirements are defined in the NWMI QAPP (Chapter 12.0, "Conduct of Operations," Appendix C). The definitions of QA Levels 1, 2, and 3 are provided below. QA Level 1 will implement the full measure of the QAPP and will be applied to IROFS. IROFS are QA Level 1 items in which failure or malfunction could directly result in a condition that adversely affects workers, the public, and/or environment, as described in 10 CFR 70.61. Examples include:
• Items to prevent nuclear criticality accidents (e.g., preventive controls and measures to ensure that under normal and credible abnormal conditions, all nuclear processes are subcritical)
• Items credited to withstand credible design-bases external events (e.g., seismic, wind)
• Items to prevent degradation of structural integrity (e.g., failure or malfunction of facility) QA Level 2 will be applied to non-QA Level 1 safety SSCs. The QA program is important to the acceptability and suitability of the item or service to perform as specified. Acceptance methods shall be specified (including acceptance and other applicable performance criteria), documented, and verified before use of the item or service. Some of the required characteristics may be examined less rigorously than for QA Level 1. Examples of QA Level 2 items include: * * * *
• SSCs to meet 10 CFR 20 normal release or exposure limits Fire protection systems Seismic detection systems Safeguards and security systems Material control and accountability systems QA Level 3 will include non-safety-related quality activities performed by NWMI that are deemed necessary to ensure the manufacture and delivery of highly reliable products and services to meet or exceed customer expectations and requirements. QA Level 3 items include those items that are not classified as QA Level 1 or QA Level 2. QA Level 3 items are controlled in accordance with standard commercial practices. 3-45 . '1

ASCE 7, Chapter 11, sets forth the criteria to which the plant design bases demonstrate the capability to function during and after vibratory ground-motion associated with the shutdown earthquake conditions. The seismic classification methodology used for the RPF complies with the preceding criteria, and with the recommendations stated in Regulatory Guide 1.29, Seismic Design Classification. The methodology classifies SSCs into three categories: seismic Category I (C-1), seismic Category II (C-11), and seismic (NS). Seismic C-1 applies to both functionality and integrity, while C-11 applies only to integrity. SSCs located in the proximity ofIROFs, the failure of which during a safe-shutdown earthquake could result in loss of function of IROFs, are designated as C-11. Specifically:

• C-1 applies to IROFs. C-1 also applies to those SSCs required to support to shut down the RPF and maintain it in a safe shutdown condition.
• C-11 applies to SSCs designed to prevent collapse under the safe-shutdown earthquake. SSCs are classified as C-11 to preclude structural failure during a safe-shutdown earthquake, or where interaction with C-1 items could degrade the functioning of a safety-related SSC to an unacceptable level or could result in an incapacitating injury to occupants of the main control room.
• NS SSCs are those that are not classified seismic C-1 or C-11. 3.5.2 Radioisotope Production Facility Systems and components within the RPF are presented in Section 3 .5 .1. The RPF design basis evaluated the general design criteria from 10 CFR 70.64, "Requirements for New Facilities or New Processes at Existing Facilities." This evaluation is presented in Table 3-23. These general design criteria provide a rational basis from which to initiate design but are not mandatory. There are some cases where conformance to a particular criterion is not directly measurable. For each of the criteria, a specific assessment of the RPF design is made, and a complete list of references is included to identify where detailed design information pertinent to each criterion is treated. The Chapter 13. 0 accident sequences for credible events define the DBE. The safety-related parameter limits ensure that the associated design basis is met for the events presented in Chapter 13.0. 3-46

• The RPF instrumentation and control (I&C) system (also known as the facility process control [FPC] system) will provide monitoring and control of the process systems within the RPF that are significant to safety over anticipated ranges for normal operations and abnormal operations. The FPC system will perform as the overall production process controller. This system will monitor and control the process instrumented functions within the RPF, including monitoring of process fluid transfers and controlled inter-equipment pump transfers of process fluids. The FPC system will also ensure that process and utility systems operate in accordance with their safety function. Controls will be provided to maintain variables and systems within the prescribed operating ranges under all normal conditions. In addition, the FPC system is designed to fail into a safe state or to assume a state demonstrated to be acceptable if conditions such as loss of signal, loss of energy or motive power, or adverse environments are experienced. The building management system (BMS) (a subset of the FPC system) will monitor the RPF ventilation system and mechanical utility systems.

The ESF parameters and alarm functions will be integrated into and monitored by the FPC system or BMS. ' The fire protection system will have its own central alarm panel. The fire protection system will report the status of the fire protection equipment to the central alarm station and the RPF control room. This integrated control system will be isolated from safety-related components consistent with IEEE 2 79, Criteria for Protection Systems for Nuclear Power Generating Stations.

SSCs co-located with C-I systems are reviewed and supported in accordance with II over I criteria. This avoids any unacceptable interactions between SSCs. C-1 structures should be designed using dynamic analysis procedures, or when justified, equivalent static procedures using both horizontal and vertical input ground motions. For dynamic analyses, either response spectra or time history analyses approaches may be used. Dynamic analysis should be performed in accordance with the procedures of ASCE 4, with the exception of the damping limitations presented in Section 3 .4 .1. Table 3-25 lists the RPF SSCs and associated safety and seismic classifications and quality level group for the top-level systems.

• Safety classification accounts for highest classification in the system. Systems that are classified as safety-related may include both safety-related and non-safety-related components. Only safety-related components will be used to satisfy the safety functions of the system, whereas non-safety-related components can be used to perform non-safety functions. For example, there are non-safety-related components, such as fans, within the safety-related ventilation systems that perform safety-related functions. b Seismic category may be locally revised to account for II over I design criteria and to eliminate potential system degradation due to seismic interactions. c Ventilation zone classifications vary -Ventilation Zone I and II are considered safety-related, C-I and QL-1; Ventilation Zone III and N are considered non-safety-related, C-II and QL-2. IROFS = items relied on for safety. RPF NSR = non-safety related. SR = Radioisotope Production Facility. = safety-related (not IROFS). SSCs that must maintain structural integrity post-DBE, but are not required to remain functional are C-11. All other SSCs that have no specific NRC-regulated requirements are designed to local jurisdictional requirements for structural integrity and are C-III. All C-1 SSCs are analyzed under the loading conditions of the DBE and consider margins of safety appropriate for that earthquake. The margin of safety provided for safety-class SSCs for the DBE are sufficient to ensure that their design functions are not put at risk. Table 3-26 presents the likelihood index limit guidelines and associated event frequency and risk index limits. 3-53 ,f.

The preliminary design basis functions and values for each major system are provided in the following subsections. Design Basis Functions *

• License conditions, orders, or technical specifications Functions credited in the safety analysis to ensure safe shutdown of the facility is achieved and maintained, prevent potential accidents, or mitigate the potential consequences of accidents that could result in consequences greater than applicable NRC exposure guidelines Design Basis Values *
• Values or ranges of values of controlling parameters established as reference bounds for RPF design to meet design basis function requirements Values may be established by an NRC requirement, derived from or confirmed by the safety analysis, or selected by the designer from an applicable code, standard, or guidance document Design Basis Criteria
• Code-driven requirements established for the RPF fall into seven categories, including fabrication, construction, operations, testing, inspection, performance, and quality * *

OA Chapter 3.0 -Design of Structures, Systems and Components 3.5.2.4 System Functions/Safety Functions The NWMI RPF will provide protection against natural phenomena hazards for the personnel, SNM, and systems within the facility. The facility will also provide protection against operational and accident hazards to personnel and the public. Table 3-2 lists the IROFS defined by the preliminary hazards analysis. 3.5.2.5 Systems and Components 3.5.2.5.1 Mechanical RPF C-1 mechanical equipment and components (identified in Table 3-25) will be qualified for operation under the DBEQ seismic conditions by prototype testing, operating experience, or appropriate analysis. The C-1 mechanical equipment is also designed to withstand loadings due to the DBEQ, vibrational loadings transmitted through piping, and operational vibratory loading, such as floor vibration due to other operating equipment, without loss of function or fluid boundary. This analysis considers the natural frequency of the operating equipment, the floor response spectra at the equipment location, and loadings transmitted to the equipment and the equipment anchorage. The qualification documents and all supporting analysis and test reports will be maintained as part of the permanent plant record in accordance with the requirements of the NWMI QAPP. The safety-related equipment and components within the RPF will be required to function during normal operations and during and following DBEs. This equipment will be capable of functioning in the RPF environmental conditions associated with normal operations and design basis accidents. Certain systems and components used in the ESF systems will be located in a controlled environment. This controlled environment is considered an integral part of the ESF systems. 3.5.2.5.2 Instrumentation and Electrical C-1 instrumentation and electrical equipment (identified in Table 3-25) is designed to resist and withstand the effects of the postulated DBEQ without functional impairment. The equipment will remain operable during and after a DBEQ. The magnitude and frequency of the DBEQ loadings that each component experiences will be determined by its location within the RPF. In-structure response curves at various building elevations have been developed to support design. The equipment (e.g., batteries and instrument racks, control consoles) has test data, operating experience, and/or calculations to substantiate the ability of the components and systems to not suffer loss of function during or after seismic loadings due to the DBEQ. This certification of compliance with the specified seismic requirements, including compliance with the requirements of IEEE 344, is maintained as part of the permanent plant record in accordance with the NWMIQAPP. 3.5.2.6 Qualification Methods Environmental qualification of safety-related mechanical, instrumentation, and electrical systems and components is demonstrated by tests, analysis, or reliance on operating experience. Testing will be the preferred method of qualification. Qualification testing will be accomplished either by tests on the particular equipment or by type tests performed on similar equipment under environmental conditions at least as severe as the specified conditions. The equipment will be qualified for normal and accident environments. Qualification data will be maintained as part of the permanent plant record in accordance with the NWMI QAPP. 3-55 NWM I .......... *. ' ......... !:* * *. ! .
