- NORTHWEST MEDfCAl ISOTOP(S N WMl-2013-021, R ev. 1 Chapter 3.0 -Des i gn of Structures, Syste m s a n d Components 3.0 DESIGN OF STRUCTURES, SYSTEMS, AND COMPONENTS This chapter identifies and describes the principal architectural and engineering design criteria for the facility structures , systems and components (SSC) for the Northwest Medical Isotopes , LLC (NWMI) Radioisotope Production Facility (RPF). The information presented emphasizes the safety and protective functions and related design features that help provide defense-in-depth against the uncontrolled re l ease of radioactive material to the environment.
The bases for the design criteria for some of the systems discussed in this chapter are developed in other chapters of the Construction Permit App l ication and are appropriately cross-referenced , when required. NWMI's RPF design is based on applicable standards , guides , codes , and criteria and provides reasonable assurance that the RPF SSCs , including electromechanical systems , are: * * * * * *
- Built and will function as designed and required by the analyses in Chapter 13. 0 , "Accident Analysis" Built to have acceptable protection of the public health and safety and environment from radiologica l risks (e.g., radioactive materials , exposure) resulting from operations Protected against potential meteorological damage Protected against potential hydrologica l (water) damage Protected against seismic damage Provided surveillance activities and technical specifications required to respond to or mitigate consequences of seismic damage Based on technical specifications developed to ensure that safety-related functions of electromechanical systems and components will be operable and protect the health and safety of workers , the public , and environment The design of the RPF and SSCs are based on defense-in-depth practices. The NRC defines design-in-depth as the following:
An approach to d es igning and op e rating nucl e ar faciliti es that prevent s and mitigate s ac c id e nt s that rel e a se radiation or ha z ardou s materials. Th e k ey i s creating multipl e ind e p e ndent and r e dundant la ye r s of d e f e n se to c omp e n s at e for potential human and m ec hanical failur es s o that no s ingl e la y er , no matter how r obu s t , i s e x clu s iv e l y r e li e d upon. D efe n se in d e pth i nclud es th e u se of access control s, phy s i c al barri e r s, r e dundant and div e rs e k ey s af e ty funct i on s , and e m e rg e n cy r es pon se m e asur es. Defense-in-depth is a de s ign phi l osophy , applied from the outset and through completion of the design , that is based on providing successive levels of protection such that health and safety are not wholly dependent on any single element of the design , construction , maintenance , or operation of the facility. The net effect of incorporating defense-in
-depth pract i ces is a conservatively designed faci l ity and systems that exhibit higher to l erances to fa il ures and external challenges. The risk insights obtained through performance of accident ana l ysis can then be used to supplement the final design by focusing attention on the prevention and mitigation of the higher risk potential accidents.

NORTMWEST MUHCAL lSOTOPH NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components This application to the U.S. Nuclear Regulatory Commi ss ion (NRC) seeks to obtain a license for a production facil i ty under Title l 0 , Code of F e d e ral R e gulation s (CFR), Part 50 (10 CFR 50), " Domestic Licensing of Production and Utilization Facilities." Embedded in the 10 CFR 50-licensed facility will be several activities subject to 10 CFR 70 , " Domestic Lic e nsing of Special Nuclear Material," to receive , possess , use , and transfer special nuclear material (SNM) and 10 CFR 30 , " Rule s of General Applicability to Domestic Licensing of Byproduct Material ," to proces s and transport molybdenum-99 (99 Mo) for medical application
- s. This 10 CFR 50 license application for the RPF follow s the guidance in NUREG-1537 , Guid e lin es for Pr e paring and R ev i e wing A ppli c ation s for th e Li ce n si n g of Non Po we r R e a c t o r s -F o rmat and Cont e nt , that encompas s e s activities regulated under different NRC requirements (e.g., 10 C FR 70 and I 0 CFR 30), in accordance w ith 10 CFR 50.31 , " Combining Applications," and 10 CFR 50.32 , " Elimination o f Repetition
." The NRC has determined that a radioisotope separation and processing facility , which also conducts separation of SNM , will be considered a production facility and as such , will be s ubject to licensing under 10 CFR 50. The operation of the NWMI RPF will primarily be focused on the di s a ss embly of irradiated low-enriched uranium (LEU) targets , separation and purification of fi s sion product 99 Mo , and the recycle of LEU that is licen s ed under I 0 CFR 50. RPF operations will also include the fabrication of LEU targets , which will be licensed under 10 CFR 70. These targets will be shipped to NWMI's network of re s earch or test reactors for irradiation (con s idered a c onnected action) and returned to the RPF for proce ss ing. The LEU u s ed for the production of LEU tar g et material s will be obtained from the U.S. Department of Energy (DOE) and from LEU reclaimed from processing the irradiated targets. NWMI's licensing approach for the RPF defines the following unit processe s and areas that fall under the following NRC regulation s: * *
- 10 CFR 50 , " Dome s tic Licensing of Production and Utilization Facilities" Target receipt and disassembly system Target dissolution system Molybdenum (Mo) recovery and purification system Uranium reco v ery and recycle system Waste management system Associated laboratory and support area s 10 CFR 70 , " Domestic Licensing of Special Nuclear Material" Target fabrication s ystem F r esh LEU (from DOE) receipt area A ss ociated laboratory and support areas 10 CFR 30 , " Rules of General Applicability to Domestic Licensing of Byproduct Material" Any byproduct materials produced or extracted in the RPF Design information for the complete range of normal operating conditions for various facility systems i s provided throughout the Construction Permit Application , and includes the following.

The basis for the structural design of the RPF is described in NWMI-2013-043 , NWM! Radioisotope Production Facility Structural D esign Ba s i s. Updates and development of technical specifications associated with the meteorological design of the RPF SSCs will be provided in Chapter 14.0 as part of the Operating License Application.
The demands on structural elements due to applied loads are evaluated using the criteria and methodology discussed below. The effect of each load case is determined separately, and total demand is determined by combining the load effects using the load combinations for evaluating strength and evaluating the serv iceability criteria given below. Four categories of load cases are used: normal , severe environmental, extreme environmental, and abnormal load s. The definition of each load is the following: * * *
- Normal loads are loads that are expected to be encountered during normal plant operations and shutdown, and load due to natural hazard phenomena likely to be encountered during the service life of the facility.
Severe environmental loads are loads that may be encountered infrequently during the service life of the facility. Extreme environmental loads are loads that are credible but are highly improbable to occur during the service life of the facility.
Abnormal loads are loads generated by a postulated high-energy pipe break accident used as a de s ign basis. Definitions of load case symbols are provided in Table 3-8. Table 3-8. Load Symbol Definitions (2 pages) Symbol Definition Norma l Load Cases D Dead loads due to the weight of the structural elements , fixed-position equipment, and other permanent appurtenant items; weight of crane trolley and bridge F Load due to fluids with well-defined pre ss ur es a nd maximum heights H Load due to lateral earth pressure, groundwater pressure , or pressure of bulk materials L Live load due to occupancy and moveabl e equipment, includin g impact Lr Roof live load C cr Rated capacity of crane (will include the ma x imum wheel load s of the crane and the vertical, lateral , and l ongitudinal forces induced by th e moving crane) S Snow load as stipu lated in ASCE 7" for risk category IV facilities R Rain load T 0 Self-staining load, thermal effects, and loads during normal operating, startup, or shutdown conditions, based on the most critical transient or steady-state condition Ro Pipe reaction s during normal operating, s tartup , or s hutdown conditions , b ase d on th e mo s t critical transient or stea dy-state co ndition 3

- 0 NOITifMST MEDICAL ISOTOP£S NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components Structural loads are due to the following: * * *
- Self-weight of building materials and SSC s Occupancy and normal use of the RPF Off-normal conditions and accidents Natural phenomena hazards Section 3.1 de s cribes the s tructural discipline s ource requirements for these crit e ria. Structural load c riteria are summar i zed below. Site-specific natural phenomena hazard criteria a re based on the phy s ical location of the RPF given in Chapter 2.0 , Sections 2.3 and 2.5. 3.2.3.1.1 Dead Loads Dead loads consist of the weight of all materials of construction comprising the building , including walls , floors , roofs , ceilings , confinement doors , stairways , built-in partitions , wall and floor finishes , and cladding. Dead loads also consist of the weight of fixed equipment , including the weight of cranes. The density of all interconnections (e.g., heating , ventilation , and air conditioning
[HV AC] ductwork , conduits , cable trays , and piping) between equipment will be conservatively estimated and included in the final design for dead load for fixtures attached to ceiling s or anchored to floors in the RPF. 3.2.3.1.2 Lateral Earth and Ground Water Pressure Loads Lateral earth and ground w ater pressure loads are lateral pressures due to the weight of adjacent soil and groundwater , respecti v ely. The design lateral earth load is a function of the composition of the soil. The Discovery Ridge Phase I En v ironmental Assessment (Terracon , 2011 a) indicates that the soils present are clayey gravels consistent with the Unified Soil Classification "GC." In addition , the assessment indicates that expansi v e soils are pre s ent. Chapter 2.0 , Section 2.5.3 present s additional on-s ite soil information. The de s ign lateral earth pre ss ure load for the RPF i s based on ASCE 7 , Table 3.2.1 , and ha s been augmented to account for the expansi v e s oils (e.g., s urcharge load is applied to account for the weight of the facility above the soils a djacent to the tank hot cell). The design groundwater depth is estimated to be approximately 5.5 meters (m) (18 feet [ft]) ground surface and will be v erified pending final g eotechnical investigation.
Additional information i s presented in Chapter 2.0 , Section 2.4.2. The lateral earth pressure loads for the RPF are presented in Table 3-12. Table 3-12.

In addition, based on NUREG-0800 , Standard Revi e w Plan for the R e view of Saf e ty Anal ys is R e port s for Nuclear Pow e r Plants , Section 3.3.1 , the wind speed will be transformed to equivalent pressure per ASCE 7-05. For RPF SSCs per current applicable 2012 IBC guidance , ASCE 7-10 is used for this transformation of wind speed to equivalent pressure.
From Table 1.5-1 of ASCE 7-10 and based on u s e and occupancy of the RPF , a Risk Category IV is assigned to RPF SSCs. Figure 26.5-I B for a Risk Category IV building of ASCE 7-10 is used to obtain the basic wind speed for the RPF site. The mean recurrence interval (MRI) of the basic wind speed for Risk Category IV buildings is 1 , 700 years. Since the MRI stipulated in ASCE 7-10 is more stringent than NUREG-1537 100-year wind speeds , wind loads will be determined in accordance with ASCE 7-10 , Chapters 26 through 30 , as applicable , for a Risk Category IV building.
The surface roughness surrounding RFP SSCs is currently Surface Category C , which in turn indicates Exposure Category C for the RFP per ASCE 7-10. The RPF main building is an enclosed building.
The wind loading criteria are provided in Table 3-15. The basic wind speed given in Table 3-15 is a 3-second (sec) gust wind speed at 10 m (33 ft) aboveground for Exposure Category C and Risk Category IV. The wind loading criteria will be updated in the Operating License Application.

NORTHWUT MEDICAL tsOTOPH NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components 3.2.4.2.1 Maximum Tornado Wind Speed Tornado wind field characteristics used to calculate tornado wind pressures on the RPF are provided in Table 3-16 per NRC Regulatory Guide 1.76. The maximum tornado wind speed has two components: translational and rotational.
The maximum total tornado wind speed is the sum of these two components and is applied to the RPF building from each direction separately. Based on NUREG-0800 , Section 3.3.2 , ASCE 7-05 may be used to transform maximum tornado wind speed to equivalent pressure. Table 3-16.

For RPF SSCs per current applicable 2012 IBC guidance , Chapters 26 and 27 of ASCE 7-10 is used for this transformation of tornado wind speed to equivalent pressure.
From Table 1.5-1 of ASCE 7-10 and based on use and occupancy of the RPF , a Risk Category IV is assigned to RPF SSCs. Per NUREG-800 , Section 3.3.2 , tornado wind speed is assumed not to vary with the height aboveground.
Additional information is provided in Chapter 2.0 , Section 2.3.1.5 , and Chapter 13.0 , Section 13.2.6. l. 3.2.4.2.2 Atmospheric Pressure Change NRC Regulatory Guide 1. 76 provides guidance for determining the pressure drop and the rate of pressure drop caused by the passing of a tornado. Depending on the final design of the RPF building and whether it is enclosed (unvented) or partially enclosed (vented structure), the procedures outlined in NUREG-800 Section 3.3.2 will be used to account for atmospheric pressure change effects. At the preliminary stage of the design, the RPF building is known not to be open. The value for atmospheric pressure drop, corresponding to the design-basis tornado is given in Table 3-16. 3.2.4.2.3 High Straight-Line Winds Similar to the tornado , high straight-line winds can also damage the facility structure, which in tum can lead to damage to SSCs relied on for safety. This evaluation demonstrates how the facility design addressed straight-line winds with a return interval of 100 years or more, as required by building codes. The RPF is designed as a Risk Category IV structure , a s tandard industrial facility with equivalent chemical hazards , in accordance with ASCE 7. The return frequency of the basic (design) wind speed for Risk Category IV structures is 5.88 x J0-4/year (MRI= 1 , 700 year). The provisions of ASCE 7 , when used with companion standards such as American Concrete Institute (ACI) 318 , Building Code Requir e ment s for Structural Concrete , and American Institute of Steel Construction (AISC) 360 , Sp ec ification for Stru c tural Ste e l Buildings , are written to achieve the target maximum annual probabilities of established in ASCE 7. The highest maximum probability of failure targeted for Risk Category IV structures is 5.0 x l0-6. 3.2.4.2.4 Tornado-Generated Missile Impact Effects Tornado-generated missile impact effects are based on the standard design missile spectrum from NRC Regulatory Guide 1. 7 6 and are presented in Table 3-17. These requirements are considered more severe than the characteristics from DOE-STD-1020 , Natural Ph e nomena Ha z ards D e sign and Evaluation Crit e ria for D e partment of En e rgy Faciliti es, that are cited in NUREG-1520 , Section 3.

The tornado load criteria will be updated by using tornado loading in accordance with 10-5 annual probability of exceedance in the Operating License Application and accordingly, the design-basis tornado missile spectrum will also be updated. 3.2.4.2.5 Combined Tornado Load Effects After tornado-generated wind pres s ure effects, atmospheric pres sure change effects and mi ssile impact effects are determined
- the combination thereof will be established in accordance with procedure s outlined n NUREG-800, Section 3.3.2. The effect of atmospheric pressure drop by itself will be considered, and the total effects of wind pressure and mis s ile impact effects with one-half of the atmospheric pressure drop effects will be considered jointly. 3.2.4.3 Effect of Failure of Structures, Systems, or Components Not Designed for Tornado Loads SSCs, in which failure during a tornado event could affect the safety-re lated portions of the RPF , are either de s igned to

3.2.5 Rain, Snow, and Ice Loading 3.2.5.1 Rain Loads From the National Weather Service (NWS)/National Oceanic and Atmospheric Administration (NOAA) Hydrometeorological Report No. 51 , Probable Maximum Pr ec ipitation Estimates , United States East of the 105th Meridian, the probable maximum precipitation (PMP) is defined as "t heoretical greatest depth of precipitation for a given duration that is physicall y possible over a particular drainage area at a certain time of yea r." Per NUREG-1537, Section 2.3.1 , " General and Local Climate," rain loads will be based on the estimate of the weight of the 48-hour (hr) probable maximum precipitation , as specified by the U.S. Geological Survey. This rain load estimate is compared with the local building code rain load (i.e., ASCE 7-10), and the greater value is used in design of the RPF roof. The roof of the RPF is de signe d to prevent rainwater from accumulating on the roof. In accordance with 2012 IBC and ASCE 7-10 , the roof structure is designed to safely support the weight of rainwater accumulation with the primary drainage system blocked and the secondary drainage system at its design flow rate when subjected to a rainfall intensity based on the 48-hr probable maximum precipitation.

The rain load criteria will be updated in the Operating License Application. 3.2.5.2 Snow Load Per the guidance in DC/COL-ISG-007, two types of snow load are considered
- normal snow load and the extreme winter precipitation load. The normal snow load will be included in normal load combinations given below. Per the guidance in the DC/COL-ISG-007 , the extreme winter precipitation load i s included in the extreme environmental load combinations.
The snow load criteria will be updated in the Operating License Application. 3.2.5.2.1 Normal Snow Load Per NUREG-1537 , Section 2.3.1 and DC/COL-ISG-007 , the normal snow load is the 100-year ground snow , modified using the procedures of ASCE 7 to determine the roof snow load , including snow drifting. The 100-year ground snow load is calculated by factoring the ground snow load stipulated in the City of Columbia Code of Ordinances amendments (City of Columbia , 2014) and IBC 20 I 2 and is equivalent to the mapped ground snow load from Figure 7-1 of ASCE 7. Thi s information is determined using the conversion factor provided in ASCE 7 , Table C7-3. The exposure factor provided in ASCE 7 , Table 7-2 , for partially exposed roof in terrain category C is similar with the exposure used for determining wind loads. Since the RPF does not fall into any of the special cases indicated in ASCE 7 , Table 7-3 , the thermal factor is assumed to be 1.0. The importance factor is taken to be unity from ASCE 7-10 , Table 1.5-2 , for the RPF , which is designated Risk Category N.

The RPF is a production facility, as opposed to a nuclear power reactor , as such 10 CFR 50.150(a)(3) is interpreted to mean that the requirement for the aircraft impact assessment is not applicable to this facility. Sources of accidental external explosions have been considered and were found to not be an accident of concern. The RPF is c onstructed of robust, noncombustible materials, and adequate setbacks from transportation routes and landscaping consisting of fire fuels are provided such that externals fires are not an accident of concern. 3-34 3.3 WATER DAMAGE NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components This section identifies the requirements and guidance for the water damage de s ign of the RPF SSCs. NUREG-1520 and ASCE 7 , Chapter 5 , provide guidance on flood protection of nuclear safety-related SSCs. Updates and development of technical specifications associated with the water damage design of the RPF SSCs will be provided in Chapter 14.0 as part of the Operating License Application. 3.3.1 Flood Protection This subsection discusses the flood protection measures that are applicable to safety-related SSCs for both external flooding and postulated flooding from failures of facility components containing liquid. A compliance review will be conducted of the as-built design against the assumptions and requirements that are the basi s of the flood evaluation presented below. Additional information is presented in Chapter 2.0 , Section 2.4.3 and Chapter 13.0 , Section 13.2.6.4. This as-built evaluation will be documented in a flood analysis report and be part of the Operating License Application.
3.3.1.1 Flood Protection Measures for Structures, Systems, and Components 3.3.1.1.1 Flooding from Precipitation Events Regional flooding from large precipitation events raising the water le v els of local streams and rivers to above the 500-year flood level can have an adverse impact on the structure and SSCs within. These impacts include the structural damage from water and the damage to power supplies and instrument control systems for SSCs relied on for safety. The infiltration of flood water into the facility could cause the failure of moderation control requirements and lead to an accidental nuclear criticality.
Direct damage or impairment of SSCs could also be caused by flooding in the facility. The site will be graded to direct the stormwater from localized downpours with a rainfall inten s ity for the 100-year storm for a I-hr duration around and away from the RPF. Thus , no flooding from local downpours i s expected based on standard industrial de s ign. Rainwater that falls on the waste management truck ramp and accumulates in the trench drain has low to no consequence for radiolo g ical , chemical , and criticality ha z ards. Situated on a ridge , the RPF will be located above the 500-year flood plain according to the flood insurance rate map for Boone County , Mi ss ouri , Panel 295 (FEMA , 2011). The s ite is above the elevation of th e nearest bodie s of water (two small ponds and a lake), and no dams are located upstream on the local streams. This data conservatively provides a 2 x 10-3 year return frequency flood , which can be considered an unlikely e vent according to performance criteria.
However , the site is located at an elevation of 248.4 m (815 ft), and the 500-year flood plain starts at an elevation of 231.6 m (760 ft), or 16.8 m (55 ft) below the site. Since the s ite , located only 6.1 m (20 ft) below the nearest high point on a ridge (relative to the local topography), is well above the beginning of the 500-year flood plain , and is considered a dry s ite , the probable maximum flood from regional flooding is considered highly unlikely , without further e v aluation.

- HOITHWEST MEDtCAL tsOTOPH NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components Per NUREG-1520, Section 3.2.3.4(1)(c), and ASCE 7 , Chapter 5, flood loads will be based on the water level of the 100-year flood (one percent probability of exceedance per year). The facility has been determined to be above both the 100-year and the 500-year flood plain. Chapter 2 , Section 2.4.3, provides additional detail for flood protection measures.
Postulated flooding from component failures in the building compartments will be prevented from adversely affecting plant safety or posing any hazard to the public. Exterior or access openings and penetrations into the RPF will be above the maximum postulated flooding level. Therefore , flood loads are considered highly unlikely and are not considered design loads. 3.3.1.1.2 Flooding from Inadvertent Discharge of Fire Protection System Water Design of fire suppression systems using water (e.g., automatic sprinklers, hose stations) includes elements such as the grading and channeling of floors , raising of equipment mounts above floors , shelving and floor drains , and other passive means. These features will ensure sufficient capacity for gravity-dri ven collection and drainage of the maximum water discharge rate and duration to avoid localized flooding and resulting water damage to equipment within the area. In addition, particularly sensitive systems and components, whether electrical, optical , mechanical and/or chemical, are typically protected within enclosures designed for the anticipated adverse environmental conditions resulting from these types of water discharges. If critical for safety, these water-sensitive systems and components will be installed within the appropriate severe environment-rated enclosures in accordance with the relevant industry standard(s) (e.g., Nationa l Electrical Manufacturers Association
[NEMA] enclosure standards).
Selection of specific fire suppression systems for facility locations will be guided by recommendations in relevant industry standards (e.g., NFPA 801, Standard for Fire Protection for Faciliti e s Handling Radioactive Materials) and will depend on the level of fire hazards at those lo cations , as determined from the final facility and process systems designs. These final detailed designs will include any facility design elements and sensitive equipment protection measures deemed necessary for addressing the maximum inadvertent rate and duration of water discharges from the fire protection systems. The final comprehensive facility design , along with commitments to design codes , standards , and other referenced documents (including any exceptions or exemptions to the identified requirements), will be identified and provided as part of the Operating License Application.
3.3.1.2 Flood Protection from External Sources Safety-related components located below-grade will be protected using the hardened protection approach. The safety-related systems and components will be protected from external water damage by being enclosed in a reinforced concrete safety-related structure.
The RPF will have the following characteristics:
- * *
- Exterior safety-r elated walls below-grade will be 0.6 I m (2-ft) thick minimum Water stops will be provided in all construction joints below-grade Waterproof coating will be applied to external surfaces below-grade and as required above-grade Roofs will be designed to prevent pooling of large amounts of water in accordance with Regulatory Guide 1.102 , Flood Protection for Nuclear Power Plants Waterproofing of foundations and walls of safety-related structures below-grade will be accomplished primarily by the use of water stops at expansion and construction joints. In addition to water stops , waterproofing of the RPF will be provided to protect the external surfaces from exposure to water. The level above the RPF first level where waterproofing is to be used will be determined in the Operating License Application. 3-36

- NOllTIIWEST MEDICAi. ISOTOHS NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components The flood protection measures that are described above will also guard against flooding from the rupture of the on-site fire protection water storage tank (if future design development determines that a fire protection storage tank is necessary).
Any flash flooding that may result from tank rupture will drain away from the RPF and thereby cause no damage to facility equipment.
3.3.1.3 Compartment Flooding from Fire Protection Discharge The total discharge from the failure of fire protection piping consists of the combined volume from any sprinkler and hose systems. The sprinkler system , if used , is capable of delivering a water density of 20 gallons per minute (gal/min) (76 liters per minute [L/min]) over a 139 m 2 (1 , 500 ft 2) design area; therefore, the sprinkler system is calculated to have a flow rate of 1, 136 L/min (300 gal/min).
The hose stream will be a manually operated fire hose capable of delivering up to 946 Umin (250 gal/min). In accordance with NFP A 801 , Section 5 .10 , the credible volume of discharge is sized for the suppression system operating for a duration of 30 min. The design of water-sensitive , safety-related equipment will ensure that potential flooding from sprinkler discharge will not adversely affect the safety features.
For example , equipment may be raised from the floor sufficiently such that the potential flooding due to sprinkler discharge will not impact the criticality analyses.
Outside of the radiologically controlled area (RCA), as defined in Chapter 11.0 , " Radiation Protection and Waste Management,'
' there is limited water discharge from fire protection systems. Any sensitive, safety-related equipment will be installed above the floor slab at-grade to ensure that the equipment remains above the flooded floor during sprinkler discharge. 3.3.1.4 Compartment Flooding from Postulated Component Failures Piping, vessels , and tanks with flooding potential in the safety-related portions of the RPF will be seismically qualified.
Water-sensitive, safety-related equipment will be raised above the floor. The depth of water on the floor will be minimized by using available floor space to spread the flood water and limiting the water volumes. Analyses of the worst flooding due to pipe and tank failures and their consequences will be developed in the Operating License Application.
3.3.1.4.1 Potential Failure of Fire Protection Piping The total discharge from the operation of the fire protection system bounds the potential water collection due to the potential failure of the fire protection piping. 3.3.1.5 Permanent Dewatering System There is no permanent dewatering system provided for the flood design. 3.3.1.6 Structural Design for Flooding Since the design PMP elevation is at the finished plant-grade and the probable maximum flood (PMF) elevation is approximately 6.1 m (20 ft) below-grade , there is no dynamic force due to precipitation or flooding. The lateral surcharge pressure on the structures due to the design PMP water level is calculated and does not govern the design of the below-grade walls. The load from buildup of water due to discharge of the fire protection system in the RCA is supported by slabs-on-grade, with the exception of the mezzanine floor. Drainage is provided for the second level in the RCA to ensure that the second level slab is not significantly loaded. The second level slab is designed to a live load of 610 kilograms (kg)/m 2 (125 lb/ft 2); therefore , the slab is capable of withstanding any temporary water collection that may occur while water is draining from that floor. 3-37

Regulatory Guide 1.60 is not indexed to any specific soil type , with its frequency content sufficiently broad to cover all soil types. Therefore , soil type for the RPF will not be a parameter used to determine the RPF's design response spectra. The composition of soil in which the RPF is embedded will be included in the interaction analysis as part of the building response analysis.
This information will be provided in the final safety analysis report (FSAR) as part of Operating License Application.
This peak ground acceleration matches that of the University of Missouri Research Reactor and the Calloway Nuclear Generating Station , which both are within 80.5 km (50 mi) of the RPF , as suggested by the NRC staff during the November I 0 , 2016 Public Meeting. The analysis procedure develops ground motion acceleration time histories that match or exceed the Regulatory Guide 1.60 spectrum as i nput to the building finite element model. Structural damping will follow the recommendations of Regulatory Guide 1.61, Damping Values for Seismic Design of Nuclear Pow e r Plants , which range from about 3 to 7 percent. Response spectra corresponding to the recommended damping values of Regulatory Guide 1.61 will be used to derive seismic loads. Damping varies depending on the type of SSC. Structural damping will follow Regulatory Guide 1.61 guidance (ranging from about 3 to 7 percent).
Plotting response spectra at 5 percent damping for purposes of illustration is a convention within the nuclear industry, but for analysis loads , damping will vary depending on the earthquake level (operating basis earthquake or safe-shutdown earthquake) and the type of SSC. Soil-Structure Interaction and Dynamic Soil Pressures The structure is supported on a shallow foundation system on stiff competent soils. The Phase 1 Assessment (Terracon, 201 la/b) stated the site is classified as Site Class C. Prescribed in ASCE 7 , Table 20.3-1 , the typical shear wave velocities for the soils present at the site are 1 , 200 to 2 , 500 ft/sec. Typical practice is to define competent soil as having a shear wave velocity greater than 1 , 000 ft/sec. The analysis of the RPF building structure to the safe shutdown earthquake will include the effects of a structure interaction. Dynamic so il pressures were determined using ASCE 4 , S e i s mic Anal y si s of Saf eR e lat e d Nucl e ar Structur es and Comm e ntary , Section 3.5.3.2, and applied to the earth retaining walls in the hot cell area.

- NOITKW£ST MEDICAL ISOTOPO Operating Basis Earthquake NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures , Systems and Components For preliminary design , the operating basis earthquake was selected to be one-third the safe-shutdown earthquake defined previously (based on Regulatory Guide 1.6 1 ). Since this option was se lected , explicit design and analysis of the facility structure for the operating basis earthquake ground-motion is not required.
3.4.1.2 Method of Analysis The effect of loads other than earthquake-induced (seismic) loads is determined by static analysis methods in accordance with ASCE 7 and the fundamental principles of engineering.
Seismic analysis of SSCs will be performed by either equivalent-static methods or dynamic analysis method s in accordance wi th ASCE 4 and ASCE 43, Seismic D esign Criteria for Structures, Systems, and Compo n e nt s in Nuclear Facilities.
The equivalent-static and dynamic seismic analysis methods are discussed below. 3.4.1.2.1 Equivalent-Static Analysis E quivalent-static seismic analysis of commercial type st ructure will be performed in accordance with ASCE 7 , Section 12.8. Direction of Seismic Loading Design ofIROFS will consider seismic loads in all three directions using a combination of the-sum-of-squared or 10/40/40 methodologies per Regulatory Guide 1.92, Combining Modal R esponses and Spatial Components in Seismic R esponse Analysis.
The I 0/40/40 methodology will be used in the development of the final RPF design and included as part of the Operating License Application. 3.4.1.2.2 Dynamic and Static Analysis Dynamic analyses are only u se d for the evaluation of RPF structural components.
A static analysis will be completed during final design by using a combination of static load computations to ensure the SSCs remain in place and intact , and a combination of existing s hake table te s t data and existing earthquake experience to ensure that the equipment functions following the earthquake.
The analysis of related s tructures may be either completed by the: *
- Linear-elastic response spectra method performed in accordance with ASCE 4 , Section 3.2.3.1, and ASCE 43 , Section 3.2.2 Linear-elastic time hi s tory method performed in accordance with ASCE 4, Section 3.2.2, and ASCE 43 , Section 3.2.2 Damping -The damping values used for dynamic analysis for the s tructural system considered will be taken from Regulatory Guide 1.6 1. Inelastic energy adsorption factors and damping values used for the analysis of nuclear safety-related structures will be selected from ASCE 43 , Table 5-1. Modeling -Finite element models will only be used for the RPF building structures.
The mesh for plate elements and member nodes will be selected to provide adequate discretization and distribution of the mass. Further , the aspect ratio of plate elements will be limited to no greater than 4: l to ensure accurate analysis results. Direction of seismic loading -Three orthogonal directions of seismic loading are used in the RPF de s ign, two horizontal and one vertical.
The modal components of the dynamic analysis and the spatial components ofresponse analysis are combined as described below. 3-39

-Spatial components are calculated separately and combined using the square-root-sum-of-the-squares method to determine the combined earthquake effect and resulting demands. Seismic Qualification of Subsystems and Equipment This subsection discusses the methods by which the RPF systems and components are qualified to ensure functional integrity.
Based on the characteristics and complexities of the subsystem or equipment , seismic qualification will be done by a combination of static load computations to ensure that the SSCs remain in place and intact , and a combination of existing shake table test data and existing earthquake experience to ensure that the equipment functions following the earthquake.
3.4.2.1 Qualification by Analysis NWMI will define specific acceptable qualification methods in the procurement packages to demonstrate seismic qualifications.
Seismic qualification of IROFS will include three options of: (1) calculations and verification that the main structural components of the SSC can withstand the seismic loads derived from the in-structure floor response spectra at the damping value derived from Regulatory Guide 1.61 , (2) reference to available shake table testing that demonstrates the seismic capacity of the SSC or of multiple similar items, and (3) demonstrat i on of the seismic capacity through the performance of the type of SSC in actual earthquakes. 3.4.2.1.1 Equivalent Static Analysis The equivalent static analysis of nuclear safety-related subsystems and equipment is performed in accordance ASCE 43, Section 8.2.1.1. The equivalent static analysis of subsystems and equipment that are not relied on for nuclear safety but are designated as a component of a seismic system per IBC 2012 , Chapter 17 , is performed in accordance with ASCE 7 , Chapter 13. 3.4.2.1.2 Static Analysis The static analysis of non-structural , safety-related subsystems and equipment is performed in accordance ASCE 4 , Section 3.2.3.1 , and ASCE 43 , Section 8.2.1.2. A portion of the seismic qualification process will involve simple static analysis of the main structural elements (anchorage and primary framing) of IROFS components , using seismic loads from in-structure response spectra derived from the RPF building structure dynamic response analysis.
In-structure response spectra are determined using ASCE 4 , Section 3 .4.2, and NRC Regulatory Guide 1.122, Development of Floor Design Response Sp e ctra for Sei s mic Design of Floor-Supported Equipm e nt or Compon e nts. In-structure floor response spectra will be developed through a finite element model of the RPF building using an artificial time history that matches or envelops the Regulatory Guide 1.60 spectrum at a peak ground acceleration

Seismic qualification of IROFS will include three options of: (1) calculations and verification that the main s tructural components of the SSC can withstand the se ismic loads derived from the in-structure floor respon se spectra at the damping value derived from Regulatory Guide 1.61, (2) reference to available s hake table te s ting that demonstrates the seismic capacity of the SSC or of multiple similar items , and (3) demonstration of the seismic capacity through the performance of the type of SSC in actual earthquakes.
Per NRC Regulatory Guide 1.100 , Seismic Qualification of Electrical and Active Mechanical Equipment and Functional Qualification of Active M ec hani ca l Equipment for Nuclea r Power Plants: *
- Active mechanical equipment relied on for or important to nuclear safety will be required to be seismically qualified in accordance with Regulatory Guide 1.100. Active electrical equipment important to or relied on for nuclear safety will be required to be seismically qualified in accordance with IEEE 344, IEEE Standard for Seismic Qualifi cation of Equipment for Nuclear Pow er Generating Stations.
Subsystems and equipment not relied on for nuclear safety but de s ignated as a component of a seismic syste m per IBC 2012, Chapter 17 , will be required.
Existing databa ses of past shake table tests will be used , such as the Office of Statewide Health Planning and Development database provided by the state of California.
These tests have typically been done based on the ICC-ES AC156, "Acce ptance Criteria for Seismic Certification by Shake-Table Testing of Nonstructural Components," spectrum.
The capacity of the standard s upport design for overhead fixtures mounted above RPF IROFS will be checked to ensure that the supports can withstand the seismic loads derived from the floor spectra (e.g., remain stable during and after postulated earthquake effects) of the attachment floor slab. Thi s information will be provided in the FSAR as part of the Operating License Application.
The RPF seismic design will also include a check to ensure that pounding or sway impact will not occur between adjacent fixtures (e.g., rattle space). Estimates of the maximum displacement of any fixture can be derived from the appropriate floor response spectrum and an estimate of the fixture's lowest response frequency.
This information will be provided as part of the Operating License Application.
3.4.3 Seismic Instrumentation Seismic recording instrumentation will be triaxial digital systems that record accelerations versus time accurately for periods between 0 and 10 sec. Recorders will have rechargeable batteries such that if there is a loss of power , recording will still occur. All instrumentation will be housed in appropriate weather and creature-proofed enclosures.
As a minimum , one recorder should be located in the free-field mounted on rock or competent ground generally representative of the site. In addition , at sites classified as Seismic Design Category D , E , or Fin accordance with ASCE 7 , Chapter 11 , using Occupancy Category IV , recorders will be located and attached to the foundations and roof s of the RPF and in the control room. The systems will have the capability to produce motion time histories. Response spectra will be computed separately.
The purpose of the instrumentation is to (1) permit a comparison of measured responses of C-1 structures and selected components with predetermined results of analyses that predict when damage might occur, (2) permit facility operators to understand the possible extent of damage within the facility immediately following an earthquake, and (3) be able to determine when an safe-shutdown earthquake event has occurred that would require the emptying of the tank(s) for inspection as specified in NFPA 59A , Standard for the Production , Storage , and H and ling of Liquefied Natural Gas , Section 4.1.3.6( c ). 3-41

- NORTHW(n 11(01CA1.ISOTOP£S NWMl-2013-021, Rev. 1 Chapter 3.0 -Design of Structures, Systems and Components Seismic instrumentation for the RPF site is not an IROFS; it provides no safety function and is therefore not "safety-related." Although the seismic recorders have no safety function , they must be designed to withstand any credible level of shaking to ensure that the ground motion would be recorded in the highly unlikely event of an earthquake. This capability requires verification of adequate capacity from the manufacturer (e.g., prior shake table tests of their product line), provision of adequate anchorage (e.g., manufacturer-provided anchor specifications to ensure accurate recordings), and a check for seismic interaction hazards such as water spray or falling fixtures.
With these design features , the instrumentation would be treated as if it were safety-related QL-2. Additional information on seismic instruction will be provided as part of the Operating License Application. 3.4.3.1 Location and Description Seismic instrumentation is installed for structural monitoring.
The seismic instrumentation consists of solid-state digital , tri-axial strong motion recorders located in the free-field , at the structure base , and at the roof of the RPF. 3.4.3.2 Operability and Characteristics The seismic instrumentation operates during all modes of RPF operations.

- NORTHWEST llEDtCAl ISOTGnS NWMl-2013-021, Rev. 1 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 SS Cs 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 ofregulatory guidance reviews , hazards and operability analysis , accident analysis , integrated s afety analysis , and national consensus code requirements is presented below. The RPF systems identified in Table 3-1 and their a s sociated 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 analy s is (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 event s for which SSCs 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 off-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.

NOkTHWEST MEOK:Al lSOTOl'lS NW Ml-2013-021, Rev. 1 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 compo n ents 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

Capability to shut down the facility and maintain it in a safe shutdown condition Capability to prevent or mitigate the consequences of postulated accidents identified through accident analyses that could result in potential offsite and worker exposures comparable to the applicable guideline exposures set forth in 10 CFR 70.6l(b), 10 CFR 70.6l(c), and 10 CFR 70.61 (d) Operation of the facility without undue risk to the health and safety of workers , the public, and the environment to meet 10 CFR 20 norma l release or exposure limits for radiation doses and applicable limits for chemical exposures Safety-related IROFS -SSCs identified through accident analyses that are required to meet the performance requirements of 10 CFR 70.6l(b), 10 CFR 70.6l(c), and 10 CFR 70.6l(d) (Table 3-2).

-SSCs that provide reasonable assurance that the facility can be operated without undue risk to the health and safety of workers, the public, and environment , and includes SSCs to meet 10 CFR 20 normal release or exposure limits. Non-safety-related
-SSCs related to the production and delivery of products or services that are not in the above safety classifications 3.5.1.3.1 Quality Group Classifications for Structures, Systems, and Components The assignment of safety-related classification and use of codes and standards conforms to the requirements NWMI's Quality Assurance Program Plan (QAPP) for the development of a Quality Group classification and the use of codes and standards.
The classification system provides a recognizable means of identifying the extent to which SSCs 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 3-7. 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. The failure of a single QA Level 1 item could result in a high or intermediate consequence. The failure of a QA Level 2 item , in conjunction with the failure of an additional item, could result in a high or intermediate consequence.
All building and structural IROFS associated with credible external events are QA Level 1. QA Level 1 items also include those attributes of items that could interact with IROFS due to a seismic event and result in high or intermediate consequences , 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) 3-45

Acceptance methods shall be specified (including acceptance and other applicable performance criteria), documented , and verified before use of the item or s ervice. Some of the required characteristics may be examined less rigorously than for QA Level 1. Examples of QA Level 2 items include: * * *

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.
These quality activities are embodied in NWMI's QAPP and will be further specified in the Operating License Application , and when necessary. 3.5.1.3.2 Seismic Classification for Structures, Systems, and Components SSCs identified as IROFS will be designed to satisfy the general seismic criteria to withstand the effects of natural phenomena (e.g., earthquakes , tomados , hurricanes , floods) without loss of capability to perform their safety functions.
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 , S e ismic De s ign Classification.
The methodology classifies SSCs into three categories:
seismic Category I (C-I), 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 of IROFS , the failure of which during a safe-shutdown earthquake could result in loss of function of IROFS , are designated as C-11. Specifically:
- C-I applies to IROFS. C-I also applies to those SSCs required to support shutdown of the RPF and maintain the facility 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. 3-46

- Instrumentation and controls Defense-in-depth Safety-related systems and components will be qualified using the applicable guidance in the Institute of Electrical and Electronics Engineers (IEEE) Standard IEEE 323, IEEE Standard for Qualifying Class 1 E Equipment for Nuclear Power Generating Stations.
The qualification of each safety-related system or component needs to demonstrate the ability perform the associated safety function: *
- Under environmental and dynamic service conditions in which they are required to function For the length of time the function is required Additionally, non-safety-related components and systems will be qualified to withstand environmental stress caused by environmental and dynamic service conditions under which their failure could prevent satisfactory accomplishment of the safety-related functions.
The RPF instrumentation and control (l&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 significa nt to safety over anticipated ranges for normal operations and abnormal operations.
The FPC system will perform as the overall production process controller.
This sys tem 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 i s designed to fail into a safe state or to assume a state demonstrated to be acceptable if conditions such as lo ss 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 BMS primary functions will be to monitor the facility ventilation system and monitor and control (turn on and off) the mechanical utility systems. ESF systems will operate independently from the FPC system or BMS. Each ESF safe ty function will use hard-wired analog controls/interlocks to protect workers, the public, and environment.
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 sta tus 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 279, Criteria for Protection Systems for Nuclear Power Generating Stations.
In addition, the RPF is designed to meet IEEE 603, Standard Criteria for Safety Systems for Nuclear Power Generating Stations, for se paration and isolation of safety-related systems and components.

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
- Codes include national consensus codes, national standards, and national guidance documents
- Design of safety-related systems (including protection systems) is consistent with IEEE 3 79 , Standard Application of th e Single-Failure Criterion to Nuclear Power G e nerating Station Safety Systems, and Regulatory Guide 1.53 , Application of the Single-Failure Criterion to Nuclear Power Plant Prot ectio n Systems
- Protection system is designed to provide two or three channels for each protective systems and functions and two logic train circuits: Redundant channels and trains will be electrically isolated and physically separated in areas outside of the RPF control room Redundant design will not prevent protective action at the system level 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 3-24) will be qualified for operation under the design basis earthquake (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 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 Electrica l C-1 instrumentation and electrical equipment (identified in Table 3-24) 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 will be 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 information will be completed during final design of the RPF and provided in the Operating License Application.

SUMMARY
DESCRIPTION Engineered safety features are active or passive features designed to mitigate the consequences of accidents and to keep radiological exposures to workers , the public , and environment within acceptable values. The engineered safety features associated with confinement of the process radionuclides and hazardous chemicals for the Northwest Medical Isotopes , LLC (NWMI) Radioisotope Production Facility (RPF) are summarized in Table 6-1 , including the accidents mitigated; structures , systems, and components (SSC) used to provide the engineered safety features; and references to subsequent sections providing a more detailed engineered safety feature description. Confinement is a general engineered safety feature that is credited as being in place as part of the preliminary hazards analysis (PHA) described in Chapter 13.0, " Accident Analysis." Additional items relied on for safety (IROFS) associated with the confinement system were derived from the accident analyses in Chapter 13 .0. The derived IROFS are also listed in Table 6-1 , with reference to more detailed descriptions in Section 6.2.1. The current design approach does not anticipate requiring containment or an emergency cooling system as engineered safety features , as discussed in Sections 6.2.2 and 6.2.3. Nuclear criticality safety is discussed in Section 6.3. Criticality safety controls are described in Section 6.3.1. The currently defined criticality safety controls are derived from a combination of preliminary criticality safety evaluations (CSE) and accident analyses , which are described in Chapter 13.0. The criticality safety analyses produce a set offeatures needed to satisfy the contingency requirements for nuclear criticality control. These features are evaluated by major systems within the RPF and listed by major system in Section 6.3.1.1 , Table 6-6 through Table 6-13. The accident analyses in Chapter 13.0 identify IROFS for the prevention of nuclear criticality , which are summarized in Table 6-2 , with reference to more detailed descriptions in Section 6.3.1.2. 6-1

- UEDICAl lSOTOPH NWMl-2013-021 , Rev. 1 Chapter 6.0 -Engineered Safety Features 6.2 DETAILED DESCRIPTIONS The PHA used to identify accidents in Chapter 13.0 , Section 13.1.3 , assumed the following known and credited safety features , or IROFS, are in place for normal operations:
- *
- Hot cell shielding boundary, credited for shielding workers and the public from direct exposure to radiation (a normal hazard of the operation)
Hot cell confinement boundaries , credited for confining the fissile and high-dose solids , liquids , and gases , and controlling gaseous releases to the environment Administrative and passive design features on uranium batch , volume , geometry , and interaction controls on the activities, credited for maintaining normal operations involving the handling of fissile material subcritical (the PHA identified initiators for abnormal operations that require further evaluation for IROFS satisfying the double-contingency principle)
This section provides detailed descriptions of the engineered safety features identified by the accident analyses shown in Chapter 13.0. 6.2.1 Confinement The PHA was based on a definition for confinement , a s follows: Confinement
-An enclosure of the facility (e.g., the hot cell area in the RPF) that is designed to limit the exchange of effluents between the enclosure and its external environment to controlled or defined pathways. A confinement should include the capability to maintain sufficient internal negative pressure to ensure inleakage (i.e., prevent uncontrolled leakage outside the confined area), but need not be capable of supporting positive internal pressure or significantly shielding the external environment from internal sources of direct radiation.
Air movement in a confinement area could be integrated into the heating , ventilation , and air conditioning (HVAC) system s, including exhaust stacks or vents to the externa l environment , filters , blowers , and dampers (ANSl/ANS-15.1 , The D eve lopm e nt of T ec hni c al Sp ec ifi c ation s for R ese ar c h R e a c tor s). Confinement describes the low-leakage boundary surrounding radioactive or hazardous chemical materials released during an accident to facility regions surrounding the physical process equipment containing process materials. The confinement systems localize releases of radioactive or hazardous materials to controlled areas and mitigate the consequences of accidents. The principal design and safety objective of the confinement system is to protect on-site workers , the public , and environment.
Personnel protection control features (e.g., adequate shielding and ventilation control) will minimize hazards normally associated with radioactive or chemical materials. The second design objective is to minimize the reliance on administrative or complex active engineering contro l s and provide a confinement system that is as s imple and fail-safe as reasonably possible. This subsection describes the confinement systems for the RPF. The RPF confinement areas will consist of hot cell and glovebox enclosures housing process operations , tanks , and piping. Confinement will be provided by a combination of the enclosure boundarie s (e.g., walls , floor , and ceiling), enclosure ventilation , and ventilation control system. The enclosure boundaries will restrict bulk quantities of process materials , potentially present in solid or liquid forms , to the confinement and limit in-leakage of gaseous components controlled by the ventilation system. The ventilation and ventilation control systems will restrict the gaseous components (including gas phase components and solid/liquid dispersions) to the confinement.
Figure 6-1 provides a simplified schematic of the confinement ventilation system , which is described in more detail as the Zone I ventilation system in Chapter 9.0 , "Auxiliary Systems." 6-5

Lower Level Confinement Boundary During normal operation, passive confinement is provided by the contiguous boundary between the hazardous materials and the surrounding environment and is credited with confining the hazards generated as a result of accident scenarios.
The boundary includes the enclosure st ructures and extension of the structures through the Zone I ventilation components.
The intent of the pa ssive boundary is to confine hazardous materials while also preventing disturbance of the ha z ardou s material inventory by ex ternal energy s ources. This passive confinement boundary extends from the isolation valve downstream of the intake high-efficienc y particulate air (HEPA) filter to the exhaust s tack. An event that results in a release of process material to a confinement enclosure wi ll be confined by the enclosure structural components.
Each process line that connects with vessels located outside of a confinement boundary with vesse ls located inside a confinement boundary will be provided with backflow prevention de v ices to prevent releases of gaseous or liquid material.
The backflo w prevention devices on piping penetrating the confinement boundary are designed as passive devices and will be located as near as practical to the confinement boundary or take a position that provide s greater safety on loss of actuating power. The consequences of an uncontrolled release within a confinement enclosure, and the off-site consequences of releasing fission products through the ventilation system, will be mitigated by use of an active component in the form of bubble-tight isolation dampers as IROFS on the inlet ventilation ducting to each enclosure.
This engineered safety feature reduce s the ducting to the confinement v olume that needs to remain intact to achieve enclosure confinement.
The dampers will close automatically (fail-closed) on lo ss of power , and the ve ntilation system will automatically be placed into the passive ventilation operating mode. Overall performance a ssurance of the active confinement components will be achieved through factory testing and in-place testing. Duct and housing leak tests will be performed in accordance with minimum acceptance criteria, as specified in ASME AG-I , Cod e o n N ucl ear Ai r and Ga s Tr e atment. Specific owner requirements with respect to acceptable leak rates will be based on the safety analysis.

Accidents mitigated consist of equipment malfunction events that result in the release of radioactive material or hazardous chemicals to a confinement enclosure.
The confinement system is also credited with mitigating the impact of a non-specific initiating event resulting in release of the iodine inventory in the dissolver off gas treatment system. 6.2.1.3 Functional Requirements Functional requirements of the confinement structural components include: *
- Capturing and containing liquid or solid releases to prevent the material from exiting the boundary and causing high dose to a worker or member of the public or producing significant environment contamination Preventing spills or sprays of radioactive solution that are acidic or caustic from causing adverse exposure to personnel through direct contact with skin , eyes, and mucus membranes where the combination of chemical exposure and radiologica l contamination would lead to serious injury and long-lasting effects Functional requirements of the confinement ventilation components include: * *
- Providing negative air pressure in the hot cell (Zone I) relative to lo wer zones outside of the hot cell using exhaust fans equipped with HEPA filters and high-efficiency gas adsorbers (HEGA) to reduce the release of radionuclides (both particulate and gaseous) outside the primary confinement boundary to below Title I 0 , Cod e of F e deral Regulations , Part 20, "Standards for Protection Against Radiation" (10 CFR 20) release limits during normal and abnormal operations.
Mitigating high-dose radionuclide releases to maintain exposure to acceptable levels to workers and the public in a highly reliable and available manner.

As an active engineered control (AEC), the primary off gas relief system wi ll be a component includ ed in the offgas train for the two irradiated target dissolvers.
The dissolver offgas system is intended to operate at a pressure that is less than the confinement enclosures to maintain gaseous components generated during dissolution within the vessels and route the gaseo us components through the offgas treatment unit operations.
The primary off gas relief system, or pressure relief tank, will be u sed to confine gases to the dissolver and a portion of the dissolver off gas equipment , if the off gas motive force (vac uum pumps) ceases operation during di ssolutio n of a dissolver batch. 6-13

Figure 6-6. Dissolver Offgas Hot Cell Equipment Location The pressure relief tank will be evacuated to a specified, subatmospheric pressure prior to initiating dissolution of a target batch and selected valves (indicated as 2 , 3, and 4 on Figure 6-5) closed. Valve I will be open during normal dissolver operation.
An upset during the dissolver operation (e.g., loss of vacuum pump operation) will result in closing Valve 1 and opening Valve 2 to contain dissolver offgas within the dissolver and off gas vessels. Due to the short duration of dissolver operation , dissolution is assumed to go to completion independent of an off gas system upset. The pressure relief tank will contain the offgas as dissolution is completed. Valves 3 , 4 , and 5 are provided for upset recovery.
After correction of the upset cause , gases collected in the pressure relief tank will be routed to the downstream treatment unit operations via Valve 3 or returned to a caustic s crubber via Valve 4. Liquid condensed in the pressure relief tank as a result of activation will be routed to the dissolver offgas liquid waste collection tank via Valve 5 for disposal.

The primary focus of the validation was to determine the bias and bias uncertainty for intermediate-enriched uranium (IEU) systems. However , sufficient experiments for low-enriched uranium (LEU) and high-enriched uranium were included to demon s trate that there is no v ariation in the USL with varying enrichment.
Similarly , the primary focus of the validation was on thermal neutron energy systems. Sufficient experiments for intermediate and fast energy experiments were also included to demonstrate that there is no variation in the USL with increasing neutron energy. The purpose of the computer code validation is to determine values of k et rthat are demonstrated to be subcritical (at or below the USL) for areas of applicability similar to systems or operations being analyzed.

NORTHWEST MED.CAL tSOTOP£S NWMl-2013-021, Rev. 1 Chapter 6.0 -Engineered Safety Features Each of the preliminary CSEs indicates that the process areas evaluated will be within the detector and alarm coverage of the CAAS. Evaluation of the CAAS coverage will be performed after final design is complete and prior to facility startup. To ensure the CAAS coverage is adequate for the facility, NWMI will conduct a coverage analysis using the minimum accident of concern that produces a detector response when the dose rate at the detector is equivalent to 20 rad/min at 2 m (6.6 ft) from the reacting material.
Using the source from the minimum accident of concern , NWMI will conduct one-dimensional deterministic computations , when practical , to evaluate CAAS coverage.
For areas of the facility where the use of one-dimensional deterministic computations is not practical , NWMI will use 3D Monte Carlo analysis to determine adequate CAAS coverage.
The CAAS will be designed to meet the following.
- *
- 6.3.1.2 The facility CAAS: Will be capable of detecting a criticality that produces an absorbed dose in soft tissue of 20 radiation dose absorbed (rad) of combined neutron and gamma radiation at an unshielded distance of 2 m from the reacting material within 1 minute; two detectors will cover each area needing CAAS coverage Will use gamma and neutron sensitive radiation detectors that energize clearly audible alarm signals if an accidental criticality occurs Will comply with ANSl/ANS-8
.3 , as modified by NRC Regulatory Guide 3.71 Will be appropriate for the type of radiation detected, the intervening shielding , and the magnitude of the minimum accident of concern Will be designed to remain operational during design basis accidents Will be clearly audible in areas that must be evacuated or there will be alternative notification methods that are documented to be effective in notifying personnel that evaluation is necessary Operations will be rendered safe , by shutdown and quarantine , if necessary , in any area where CAAS coverage has been lost and not restored within a specified number of hours. The number of hours will be determined on a process-by-process basis , because shutting down certain processes, even to make them safe , may carry a larger risk than being without a CAAS for a short time. Compensatory measures (e.g., limiting access , halting SNM movement, or restoring CAAS coverage with an alternate instrument) when the CAAS is not functional will be determined for inclusion in the Operating License Application.
Emergency power will be provided to the CAAS by the uninterruptable power supply system . Derived N u clear Criticality Safety Items Relied o n for Safety The following subsections describe engineered safety features that are derived from the accident scenarios that could result in a nuclear criticality, as described in Chapter 13.0. 6.3.1.2.1 IROFS CS-04, Interaction Contro l Spacing Provided by Passively Designe d Fixtures and Wo r kstation Placement IROFS CS-04 , " Interaction Control Spacing Provided by Passively Designed Fixtures and Workstation Placement," is identified by the accident analyses in Chapter 13.0.

LEU target material (including movement of LEU target material to and from the fabrication workstation and handling of the completed targets) Disassembly of targets following irradiation Laboratory sampling and analysis activities (albeit in smaller quantities) . Each activity is assigned a mass or batch limit for safe handling.
Accident Mitigated The accident occurs when a safe mass or batch limit is exceeded beyond some bounding extent based on the management measures on the control. Note that this accident involves normal condition criticality controlled limits for safe handling, and the upset represents failure of an associated administrative control. The most limiting activity would involve processing the LEU target material from [Proprietary Information].
If the IROFS fails , accidental nuclear criticality is possible without additional control. System Components As a PEC , fixed interaction control fixtures or workstations will be provided for holding or processing approved containers containing approved quantities of uranium metal , [Proprietary Information], batches of targets , and batches of samples. Functional Requirements The fixtures are designed to hold only the approved container or batch and are fixed with 2-ft edge spacing from all other fissile material containers , workstations , or fissile solution tanks, vessels, and ion exchange (IX) columns. Where LEU target material is handled in open containers , the design will prevent spills from readily spreading to an adjacent workstation or storage location. Design Basis Final workstation and fixture spacing will be determined in final design when all process upsets are evaluated.

The PHA in Chapter 13.0 identified a number of individual potential initiating events that could lead to a spill of fissile solution from the geometrically safe confinement tanks , vessels , or piping that provide the primary safety functions of the processes.
Four processing systems will handle fissile solutions:
Target fabrication (from the [Proprietary Information])
Target dissolution system First stage of molybdenum recovery and purification Entire uranium recovery and recycle sy s tem Three of these systems will be at least partially located within the hot cell wall boundary due to the dose of the fission products.
Initiating events include the general categories of tank , vessel , or piping failure due to operator error (valves out of position), valves leaking , equipment leaking (pumps , piping , vessels , etc.), high pressure events from various causes including high temperature solutions (locked in boundary valves), hydrogen detonation , and exothermic reactions with the wrong resins or reagents used in the respective systems. Some of the initiators result in small leaks that are identified and mitigated (e.g., pump seal and small valve leaks). Over the life of the facility , these types of leaks are to be expected , but do not challenge the overall safety of RPF operations.
Accident Mitigated The accident of concern involves fissile process solution in quantities necessary to sustain accidental nuclear criticality.
Larger catastrophic leaks or ruptures of equipment must occur for enough material to be released. Such leaks would represent a failure of the safe-geometry confinement IROFS for the respective equipment.
Thus , scenarios leading to this accident sequence involve the failure of these IROFS. Due to the nature of the process , the worst-case accident involves the tanks with the largest capacity and the highest normal case concentrations.
System Components As a PEC , pencil tanks and other standalone vessels are designed and will be fabricated with a geometry diameter for safe storage and processing of fissile solutions.
The safe diameters of various tanks , vessels , or components will be provided in the Operating License Application.
Functional Requirements The safety function of safe diameter vessels is also one of confinement of the contained solution.
The safe-geometry confinement of fissile solutions will prevent accidental nuclear criticality, a high consequence event. The safe-geometry confinement diameter will conservatively include the outside diameter of the tank wall or out to the outside diameter of any heating or cooling jackets (or any other void spaces that may inadvertently capture fissile solution) on the vessels. Where insulation is used on the outside wall of a vessel , the insulation will be closed foam or encapsulated type (so as not to soak up solution during a leak) and will be compatible with the chemical nature of the contained solution. Design Basis The safe-geometry diameter of tanks , vessels , and piping will be determined in final design after finalizing the reference CSEs. Note that preliminary vessel sizes for activity groups are listed in the double-contingency parameters described in Section 6.3.1.1. 6-61

System Components As a PEC , pencil tanks and other standalone vessels (controlled with s afe geometry or volume constraints) are designed and will be fabricated with a fixed interaction spacing for safe storage and processing of the fissile solutions.
Tanks, vessels, and components requiring fixed interaction control spacing of the barrels within each set of pencil tanks and between various tanks , vessels , or components will be provided in the Operating License Application.
Functional Requirements The safety function of fixed interaction spacing of individual tanks in pencil tank s and between other single processing vessels or components is designed to minimize interaction of neutrons between vessels such that under normal and credible abnormal process upsets , the systems remain subcritical.
The fixed interaction control of tanks , vessels , or components containing fissile solutions will prevent accidental nuclear criticality , a high consequence event. The fixed interaction spacing will be measured from the outside of the respective tanks, vessels, or component or from the outside of any heating or cooling jackets (or any other void spaces that may inadvertently capture fissile solution) on the vessels or component.
The fixed interaction control distance from the safe slab depth spill containment berm will also be specified where applicable.
Design Basis Actual interaction control parameters will be defined during final design. In addition , the following generic interaction control parameters apply during design. *
- Connecting piping between fissile material components will not exceed a cross-sectional density to be determined during final evaluation of systems. Edge-to-edge spacing between fissile material-bearing vessels and components and the concrete reflector presented by the hot cell shielding walls will be fixed at a distance to be determined during final evaluation of all components.

System Components As a PEC, the floor under designated tanks , vessels , and workstations will be constructed with a spill containment berm using a safe-geometry slab depth , and one or more collection sumps with diameters or depths, to be determined in final design. Functional Requirements The safety function of a spill containment berm is to contain spilled fissile solution from systems overhead and prevent an accidental nuclear criticality if one of the tanks or related piping leaks , ruptures , or overflows (if so equipped with overflows to the floor). Each spill containment berm will be sized for the largest single credible leak associated with overhead systems. The sump will have a monitoring system to alert the operator that the IROFS has been used and may not be available for a follow-on event. A spill containment berm is operable if it contains reserve volume for the largest single credible spill. Spill containment berm sizes and locations will be determined during final design. Design Basis The safe-geometry slab depth under designated tanks , vessels , and workstations will be determined during final design after finalizing the reference CSEs. Note that the preliminary slab depth for the activity groups are listed in the double-contingency parameters described in Section 6.3.1. l.

," is identified by the accident a n a l yses described in Chapter 13.0. As an AEC , the condensate tanks will use a continuous active uranium detection system to detect high carryover of uranium that s hut s down the evaporator feeding the tank. The purpose of this system is to (I) detect an anomaly in the evaporator or concentrator indicating high uranium content in the condenser (due to flooding or excessive foaming), and (2) prevent high concentration uranium solution from being available in the condensate tank for discharged to a favora ble geometry system or in the condenser for l eaking to the non-safe geometry coo ling loop. Accident Mitigated The s afety function of this IROFS is to prevent an accidenta l nuclear critica lit y because of excessive uranium in the condensate carryover to a non-geometrically favorable waste collection tank.

NWMI ..*... ..* *.. **** 0 :.!! *. 0 NORTHWEn MEOK:Al tSOTOPEI Functional Requirements NWMl-2013-021, Rev. 1 Chapter 6.0 -Engineered Safety Features The detection system works by continuously monitoring condensate uranium content and detecting high uranium concentration, and then shutting down the evaporator to isolate the condensate from the condenser and condensate tank. At a limiting setpoint, the uranium monitor detecting device will close an isolation valve in the inlet to the evaporator (or otherwi se secures the evaporator) to stop the discharge of high uranium content solution into the condenser and condensate collection tank. The uranium monitor is designed to produce a valve-open permissive signal that fails to an open state, closing the valve on loss of electrical power. The isolation valve is designed to fail-closed on loss of instrument air, and the solenoid is designed to fail-closed on loss of signa l. Locations where these IROFS are u sed will be determined during final design. Design Basis Design basis information will be provided in the Operating License Application.

6.3.1.2.15 IROFS CS-26, Processing Component Safe Volume Confinement IROFS CS-26 , " Processing Component Safe Volume Confinement," is identified by the accident analyses described in Chapter 13.0 (see description in Section 6.3.1.2.2).
Accident Mitigated See description in Section 6.3.1.2.2. System Components As a PEC , some processing components (e.g., pump s, filter housings , and IX columns) will be controlled to a safe volume for safe storage and proce ssi ng of the fissile solutions.
Components that may be controlled to a safe volume will be described in the Operating License Application. Functional Requirements The safety function of a safe-volume component is also one of confinement of the contained solution.
The safe-volume confinement of fissile solutions will prevent accidental nuclear criticality , a consequence event. The safe-volume confinement will conservatively include the outside diameter of any heating or cooling jackets (or any other void spaces that may inadvertently capture fissile solution) on the component.
Where insulation is used on the outside wall of the component , the insulation will be foam or encapsulated type (so as not to soak up solution during a leak) and will be compatible with the chemical nature of the contained solution. Design Basis The safe-volume confinement components will be determined in final design after finalizing the referenced CSEs. 6-70

6.3.1.2.16 IROFS CS-27 , Closed Heating or Cooling Loop with Monitoring and Alarm IROFS CS-27 , " Closed Heating or Cooling Loop with Monitoring and Alarm ," is identified b y the accident analyses in Chapter 13.0. As a PEC , closed cooling water loops with monitoring for breakthrough of proce ss solution will be provided on the evaporator or concentrator condensers to contain process solution that leak s across this boundary , if the boundary fails. This IROFS will be applied to those high-heat capacity cooling jackets (requiring very large loop heat exchangers) servicing condensers where the leakage is always from the cooling loop to the condenser.
The inherent characteristics of the leak path will reduce back-leakage into the closed loop syste m , and the risk of product solutions entering the condenser will be very low by evaporator and concentrator de sign. System Components The purpose of this safety function i s to monitor the he a lth of the condenser cooling jacket to ensure that in the unlikel y event that a co ndenser overflow occurs , fissile and/or high-dose process solution will not flow into thi s non-safe-geo metry cooling loop and cause nuclear criticality.
The closed loop will also isolate any high-dose fis s ile product solids , from the same event, from penetratin g the hot cell s hielding boundary , and any high-do se fission gases from penetratin g the hot cell shielding boundary during normal operations.
Functional Requirements The heat exchanger materials will be compatible with the harsh chemical environment of the tank or vesse l proce ss (t hi s may vary from application to application).
Sampling of the cooling media (e.g., coo lin g water radiological activ ity , or uranium concentration) will be conducted to alert the operator that a breach ha s occurred, and that a dditional co rr ect i ve actions are required to identify and i so late the failed component and re s tore the c lo se d-loop integrity.
Closed-loop pres sure will also b e monitored to identify a leak from the closed loop to the proc ess sys tem. Di sc har ge d so lutions from this sys tem will be handled as potentiall y fissile and sa mpled prior to discharge to a non-safe geometry.

SUMMARY
DESCRIPTION The Northwest Medical Isotopes , LLC (NWMI) Radioisotope Production Facility (RPF) preliminary instrumentation and control (I&C) configuration includes the special nuclear material (SNM) preparation and handling processes (e.g., target fabrication , and uranium recovery and recycle), radioisotope extraction and purification processes (e.g., target receipt and disassembly , target dissolution , molybdenum
[Mo] recovery and purification , and waste handling), process utility systems , criticality accident alarm system (CAAS), and sy s tems associated with radiation monitoring.
The SNM processes will be enclosed predominately by hot cells and glovebox designs except for the target fabrication area. The facility process control (FPC) system will provide monitoring and control of the process systems within the RPF. In addition, the FPC system will provide monitoring of related components within the RPF. The process strategy for the RPF involves the use of batch or batch processes with relatively simple control steps. The building management system (BMS) (a subset of the FPC system) will monitor the RPF ventilation system and mechanical utility systems. The BMS primary functions will be to monitor the facility ventilation system and monitor and control (turn on and off) the mechanical utility systems. Engineered safety feature (ESF) systems will operate on actuation of an alarm setpoint reached for a specific monitoring instrument/device. For redundancy , this will be in addition to the FPC system or BMS ability to actuate ESF as needed. Each ESF safety function will use hard-wired analog controls/interlocks to protect workers, the public , and environment.
The ESF parameters and alarm functions will be integrated into and monitored by the FPC system or BMS. The preliminary concept for the RPF l&C system configuration is shown in Figure 7-1. The green circles identify the FPC and the BMS distributed process control or programmable logic controller (PLC) s ystems. The solid lines and dashed lines show how the SNM processes , support systems , utilities , radiation and criticality systems , and building functions relate to the FPC and BMS and to local machine interface (HMI) stations.
Solid lines indicate the control functions , and dashed lines indicate the monitoring functions. 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. Process control systems are described further in Section 7.3. The fire protection system will have its own central alarm panel (green circle). The fire protection system will report the status of the fire protection equipment to the central alarm station and the RPF control room. The fire protection s ystem is discussed further in Section 7.2.3.5. 7-1

The FPC system will be a digital control system (DCS) that monitors safety-related components within the RPF. The ESFs will be integrated into the FPC systems and provide a common point of HMI , monitoring , and alarming at the control room and , as necessary , local HMI workstations.
Control Console and Display Instruments The control room will be the primary interface location for the RPF support systems and provide centralized process controls, monitoring, alarms, and acknowledgement.
Mechanical utility systems with vendor packages and integrated controls will be controlled at associated local HMi s. The BMS will provide primarily on/off control and system monitoring from the control room. The tank hot cell processes will be controlled primarily in the control room, with surveillance monitoring of the FPC subsystems.
The FPC system will have annunciation, alarms, and HMI displays.
From the consoles, operators will view and trend essential measurement values from the HMI display, and evaluate real-time data from the essential measurements used to control and monitor the RPF process. This system is further described in Section 7.5. Process utility and support systems with vendor package and integrated controls will be operated at associated local HMis. These systems are discussed further in Section 7.5. Local HMis are anticipated in the following locations:

NORTHWEST MEDUl ISOTOPH NWMl-2013-021, Rev. 1 Chapter 7.0 -Instrumentation and Control Systems 7.2.3.1 Facility Process Control System The FPC system controls and monitors the target fabrication system, hot cell area (e.g., Mo recovery and purification, uranium recovery and recycle system), process utility and support systems , and waste handling activities.
The FPC system functions also include radiation monitoring, CAAS , HMis , safe shutdown control and initiation , supervisory information , and alarms. The BMS is a subsystem to the FPC system and monitors the facility ventilation system. The primary control location of the FPC system is in the control room. The control room FPC system operates with a synchronized hot standby redundant system structure. The hot standby workstations provide redundant hardware with identical PLC software systems as automatic backup control systems. The primary and backup PLC systems monitor each other. On loss of synchronizing signal from one system, the other system continues with control and monitoring.
This automatic backup control system minimizes the likelihood of downtime during Mo production processing. 7.2.3.2 Engineered Safety Feature Actuation Systems The operator will have direct visualization of critical values and the ability to observe status of the features described in Table 7-13 (Section 7.4.1). The engineered safety feature actuation system dedicated displays will perform the following functions: * *
- Static display -This display will show critical measurement values and perform the function of an annunciator panel. This fixed display panel will not provide any interactive control functionality.
Alarm/event annunciator display panel -This panel will display any event or alarm that is defined for the process. The display will enable the operator to acknowledge current events and alarms , and will provide a historical record of events. Dynamic interface display panel or HMI -This panel will enable the operator to perform tasks , change modes, enable/disable overrides , and other tasks that require operator input to allow , perform , or modify a task or event. The set of displays will be arranged in a workstation. This workstation will also include a keyboard and mouse that will be used to interface with the system. 7.2.3.3 Control Room/Human-Machine Interface Description The operator will have direct visualization of critical values and the ability to input control functions into the FPC system. The FPC system dedicated displays will perform the following functions: * *
- Static display -This display will show critical measurement values and perform the function of an annunciator panel. This fixed display panel will not provide any interactive control functionality.

The primary purpose of the BMS is to control the air balance of the facility ventilation system and to shut down the facility ventilation system in the event of receiving an alarm from the fire protection system or off-normal conditions indicated by the FPC or engineered safety features.
The operator will have direct visualization of critical va lues and the ability to input control functions into the BMS. The BMS dedicated displays will perform the following functions in the control room: * *
- Static display -This display will show critical measurement values and perform the function of an annunciator panel. This fixed display panel will not provide any interactive control functionality.
Alarm/event annunciator display panel -This panel will display any event or alarm that is defined for the process. The display will enable the operator to acknowledge current events and alarms, and will provide a historical record of events. Dynamic interface display panel or HMI -This panel will enable the operator to perform task s , change modes , enable/disable overrides, and other ta s ks that require operator input to allow , perform , or modify a task or event. The set of displays will be arranged in a workstation.
This workstation will also include a keyboard and mouse that will be used to interface with the system. 7.2.3.5 Fire Protection System The fire protection system will report the status of the fire protection equipment to the central alarm s tation and the RPF control room with sufficient information to identify the general location and progres s of a fire within the protected area boundaries.
Initiating devices for the fire detection and alarm s ubsystem , including monitoring devices for the fire s uppression subsystem, will indicate the presence of a fire within the facility.
Once an initiating device activates, signals will be sent to the fire alarm control panel. The fire alarm co ntrol panel will transmit signa ls to the central alarm station and perform any ancillary functions. As an example , signals from the fire control panel may initiate actions such as shutdown of the ventilation equipment or actuating the deluge valves. The fire protection system is described in Chapter 9.0 , Section 9.3. 7.2.3.6 Facility Communication Systems The RPF communication sys tems will relay information within the facility durin g normal and emergency conditions.
The sys tems are designed to enable the RPF operator on duty to be in communication with the supervisor on duty , health physics staff, and other personnel required by the technical specifications, and to enable the operator , or other staff, to announce the existence of an emergency in all areas of the RPF complex.

Samples from the process will be collected , transported to the laboratory , and prepared in the laboratory gloveboxes and hoods, depending on the analysis to be performed. The analytical laboratory equipment will be provided as vendor package units. Control room monitoring of the analytical laboratory will be limited to the facility systems , including ventilation and radiation monitoring systems. Analytical laboratory system is described in Chapter 9.0 , Section 9.7.3. 7.2.4 System Performance Analysis The RPF I&C system will monitor the processes and ESFs when required.
The IROFS will be managed by the FPC system. The FPC system will provide the central decision-making processor that evaluates monitored parameters from the various plant instrumentation and from the radiation monitoring systems of the CAMs , CAAS , and RAMs. The analysis herein discusses safety as it relates to the IROFS design criteria and design basis. Potential variables , conditions , or other items that will be probable subjects of technical specifications associated with the RPF I&C systems are provided in Chapter 14.0 , "Technical Specifications
." 7.2.4.1 Facility Trip and Alarm Design Basis The design basis information for the FPC system trip functions is based on the following two requirements from Title 10, Cod e of F e d e ral R e gulation s, Part 70 (10 CFR 70), " Domestic Licensing of Special Nuclear Material." *
- Double-contingency principle
-Process designs should incorporate sufficient factors of safety to require at least two unlikely, independent , and concurrent changes in process conditions before a criticality accident is possible (baseline design criteria of 10 CFR 70.64 , "Requirements for New Facilities or New Processes at Existing Facilities
," paragraph
[9]). The safety program will ensure that each IROFS will be available and reliable to perform its intended function when needed and in the context of the performance requirements of this section (10 CFR 70.61, " Performance Requirements
," paragraph
[e]). The FPC system trip and alarm annunciation are protective functions and will be part of the overall protection and safety monitoring systems for the RPF. The specific equipment design basis for the instrumentation and equipment used for the FPC system trip and alarming functions is discussed in Section 7.2.2. The following discussion relates to the design basis used for monitoring specific signal values for RPF trips and alarms , requirements for performance , requirements for specific modes of operation of the RPF and the FPC system , and the general design criteria noted in Table 7-1. 7.2.4.1.1 Safety Functions Corresponding Protective or Mitigative Actions for Design Basis Events IEEE 603-2009, IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations (Sections 4a and 4b). The results of the integrated safety analysis (ISA) for the RPF structures , systems, and components (SSC) are discussed in Chapter 13.0 , " Accident Analysis." Conditions that require monitoring and the subsequent action to be taken are described in Chapter 13.0. 7-16

The associated design criteria are discussed in Sections 7.2.1 and 7.2.2. The following discussions relate to conformance to the criteria for the FPC system trip function. 7.2.4.2.2 General Functional Requirement Conformance IEEE 603-2009 (Section 5). The FPC system will initiate and control ESF activation and isolation when the system detects an off-normal event appropriate for activation. The FPC system trips are discussed in Section 7 .2.4.1. These monitored values and subsequent trips are a re s ult of the preliminary accident analysis in Chapter 13.0 and provide a means to mitigate or reduce the consequences from the design basis accident to acceptable levels. 7.2.4.2.3 Requirements on Bypassing Trip Functions Conformance IEEE 603-2009 (Sections 5.8, 5.9, 6.6, and 6.7). Trip override or bypass is recognized as a design requirement.
Channel bypass will be allowed based on the nature of the signal. No channel bypass will be allowed without a visual indication on the FPC system display and recording the bypass event in the historical log. 7.2.4.2.4 Requirements on Setpoint Determination and Multiple Setpoint Conformance IEEE 603-2009 (Section 6.8). Table 7-1 discusses the criteria to be used for setpoint derivation. Setpoints will be calculated in accordance with ISA-RP-67.04.02 , M e thodologi es f o r th e D e t e rmination of S e tpoints for N ucl e ar Saf ety-R e lat e d Instrum e ntation. 7.2.4.2.5 Requirements for Completion of Trip Conformance IEEE 603-2009 (Section 5.2). The ESF and the interaction of a mitigative action going to completion will be provided in the design. The FPC system will monitor for a complete trip of the ESF. This information will be available on the operator display for the FPC system and at the local HMI terminals near the hot cell. An alarm/event annunciation will be displayed to the operator.
Section 7.4.1 describes the activation of the ESF , alarm/event strategy , and operator requirements to manually reset the system after a facility trip. 7.2.4.2.6 Requirements for Manual Control of Trip Conformance IEEE 603-2009 (Section 6.2). The FPC system will have the ability to perform a manual activation of the ESF. Section 7.4.1 describes the activation of the ESF , alarm/event strategy , and operator requirements to manually reset the system after a facility trip. 7-17 "NWMI ...... *.t: ** :.::: .. *****. * *. *

SNM preparation and handling processes include uranium recovery and recycle , and target fabrication. Radioisotope production processes include target receipt and disassembly , target dissolution , Mo recovery and purification , and waste handling. The RPF process control will be administered by the FPC system and is described in Section 7.2.3. The FPC system will perform the following high-level process functions.

Monitor and control inter-equipment process fluid transfers in the RPF -For transport requiring a pump , the FPC system will control the ability of the pump to be energized.
For specific transfers , the FPC system will provide controlled fluid flow transfers based on a loop flow control. The operator wil 1 initialize the transfer of fluids. Other process fluid transfers , including: Dissolved low-enriched uranium (LEU) solution to the Mo recovery and purification system Uranium solution to the uranium recovery and recycle system Liquid wastes to the waste handling system The I&C system for process utilities and support systems and for the ventilation systems will be described in more detail in the Operating License Application.

Two cycles of uranium purification will be included to separate uranium from unwanted fission products using ion exchange. The first ion exchange cycle will separate the bulk of the fission product contaminant mass from the uranium product. Product will exit the ion exchange column as a dilute uranium stream that is concentrated to control the stored volume of process solutions.
Uranium from the first cycle will then be purified by a nearly identical second cycle system to further reduce fission product contaminants to satisfy product criteria.
Each ion exchange system feed tank will include the capability of adding a reductant and modifying the feed chemical composition such that adequate separations are achieved , while minimizing uranium losses. 7-22

The collection container will move through the pass-through to a dissolver basket positioned over a dissolver , the target material will then be dissolved and the resulting solution transferred to the Mo recovery and purification system. Target dissolution of irradiated LEU will result in gaseous fission products (iodine [I], krypton [Kr], and xenon [Xe]) with very high radiation fields. A primary function of the process offgas systems will be to control release of these gases both internal and external to the facility. The dissolver off gas treatment system will include the nitrogen oxide (NO x) treatment and fission gas treatment subsystems. Due to the variety of process activities performed during target dissolution , the system description is divided into the following subsystems:

The control room will consist of a properly sized and shaped control console with two or three operator interface stations or HMis (one being a dedicated engineering interface), a master PLC or distributed controller , and all related and necessary cabinetry and subcomponents (e.g., input/output boards , gateways , Ethernet switches , power supplies , and UPS). This control system will be supported by a data highway of sensing instrument signals in the facility process areas that will be gathered onto the highway throughout the facility by an Ethernet communication-based interface backbone and brought into the control room and onto the console displays.
Dedicated controllers and human-machine monitoring interfaces or stations for other equipment systems will also be in the control room. This equipment includes the facility crane , closed-circuit television system, CAAS , and radiation monitoring system. A control panel for all facility on-site and off-site (if required) communications (e.g., telephone , intercom) will likely also be located there. The control room door into the facility will be equipped with controlled access. The BMS will be primarily controlled and monitored from the control room. Utility systems with vendor packages and integrated controls will provide surveillance monitoring to the control room. The FPC system will operate with a synchronized hot s tandby redundant system structure for all hot cell processes.
Each hot cell process will be an independent subsy s tem having a local HMI with monitoring and control functions from the control room. Workstations for each system within the control room will be hot standby redundant.
The redundant stations will run software on identical PLC systems. The PLC systems will monitor each other. On loss of synchronizing signal from one system, the other system will continue with control and monitoring. Process systems that will be primarily controlled in the control room include uranium recovery and recycle , target dissolution , and liquid waste handling. The target receipt system will be controlled with local HMis in the irradiated target basket receipt bay or target cask preparation airlock. Mo production process hot cell systems , including target disassembly and Mo recovery and purification, will be controlled with local HMis in the hot cell operating gallery. The hot cell processes will have monitoring and redundant control functions from the control room. The FPC subsystem for target fabrication processes will be controlled with local HMis in the target fabrication area , with surveillance monitoring in the control room. Local HMis will be provided in Room W107 , which houses equipment for low-dose waste solidification. Low-dose liquid waste will be piped in from the holding tanks in the utility area above Room W107 , and drums of solidified waste will be transported out by pallet jack. This local HMI will be the primary control location for the high-dose liquid waste solidification , high-dose waste decay, spent resin dewatering , and solid waste handling hot cell operations. 7.5.4 System Performance Analysis and Conclusion The system performance analysis for each process system will be provided in the Operating License Application.

NORTifWESTMEDtcAllSOTOP£S NWMl-2013-021, Rev. 1 Chapter 7.0 -Instrumentation and Control Systems 7.6 RADIATION MONITORING SYSTEMS The radiation monitoring systems will include CAMs , continuous monitoring at the exhaust stacks, process control instruments , and personnel monitoring and dosimetry. Process control instruments used to analyze for uranium concentrations are described in each respective process system in Section 7.3. The objective of the radiation monitoring system is to provide the RPF control room personnel with a continuous record and indication of radiation levels at selected locations where radioactive materials may be present , stored, handled , or inadvertently introduced.
The system is also designed to ensure that there is accurate and reliable information concerning radiation safety as related to personnel safety. The design considerations for the radiation monitoring system include the following: * *
- Provision of information to RPF operators so that in the event of an accident resulting in a release of radioactive material , decisions on deployment of personnel can be properly made. Indication and recording in the control room of the gamma and airborne radiation levels in selected areas as a function of time , and , if necessary, alarming to indicate any abnormal radiation condition.
These indicators aid in maintaining plant contamination levels as low as reasonably achievable (ALARA) and in minimizing personnel exposure to radiation.
Provision oflocal alarms and/or indicators positioned at key points throughout the RPF where a substantial increase in radiation levels might be of immediate importance to personnel frequenting or working in the area. Radiation Monitoring Locations RAMs will be located in areas where personnel may be present and where radiation levels could become significant based on the following considerations
- * *
- Occupancy status of the area , including time requirements of personnel in the area , the proximity to primary and secondary radioactive sources , and shielding Potential for increase in the background radioactivity level Desirability of surveillance of infrequently v i s ited areas CAMs will be located in work areas where there is a potential for airborne radioactivity. The CAMs will have the capability to detect derived air concentrations within a specified time. 7.6.1 Design Criteria Design criteria for the radiation monitoring I&C sy s tems are described in Section 7.2. 7.6.2 Design Basis and Safety Requirements The design basis and safety requirements for the radiation monitoring I&C systems are described in Section 7.2. The ESFs for this system are listed in Chapter 6.0. 7.6.3 System Description The radiation safety monitoring system will include CAMs , continuous monitors at the exhaust stacks , and personnel monitoring and dosimetry.

- NO<<rHW£STMEOfCALISOTOPES NWMl-2013-021 , Rev. 1 Chapter 7.0 -Instrumentation and Control Systems Three basic types of personnel monitoring equipment will be used at the facility:
count rate meters (friskers), hand/foot monitors , and portal monitors. All personnel whose duties require entry to restricted areas will wear individual external dosimetry devices (e.g., passive dosimeters such as thermoluminescent dosimeters that are sensitive to beta , gamma, and neutron radiation) from a National Voluntary Laboratory Accreditation (NAVLAP)-certified vendor. Personnel monitoring and dosimetry is described in Chapter 11.0, "Radiation Program and Waste Management." 7.6.3.1 Air Monitoring Continuous air monitors -CAM units will consist of a particulate measuring channel with a filter to capture particulate. Air will be drawn through the system by a pump assembly.
The sample will be withdrawn from inside the appropriate area , room , or cell through an isokinetic nozzle with the sampling volume flow at a known fixed rate , so that the accumulation of radioactive particles can be interpreted as a quantitative sample. After passing through the nozzle , the sample will be drawn through tubing and through a fixed or moving filter tape before being discharged to the atmosphere.
The samplers also have a purging system for flushing the volume cell surrounding the gas sample chamber with clean air for purposes of calibration and the removal of crust activity. Replaceable liners will be changed out periodically when contamination becomes excessive. Flow regulating will ensure that flow through the filters remains constant.
Each instrument channel will include a detector , preamplifier , count rate meter , and power supply. The detector may be a scintillation counter or similar device having a gamma sensitive crystal , and a photo multiplier whose output pulses are counted by the rate meter. Each readout module will be equipped with a light that illuminates when the radiation level exceeds preset limits. The setpoint will be adjustable over the entire detection range. Pressing a button will cause the meter to indicate the alarm setpoint.
Visible alarms will be accompanied by a simultaneous local audible a larm with an alarm light in the control room. A normally energized light will deenergize when there is a detector signal failure , circuit failure , power failure , or failure due to a disconnected cable. Power for the monitor s that initiates a safety signal will be provided from the UPS. Loss of power and signal failure will be monitored for each detector.
CAMs will be provided with a check source. This check source will simulate a radiation field and will be used as a convenient operational and gross calibration check of the detectors and readout equipment.
CAM calibration will include , where practical , exposures to the s pecific isotopes that the particular system monitors in the field. Instrument calibrations will be performed at prescribed frequencies. An electronic test signal and/or radioactive check source drift indication may also require CAM recalibration. Radiation area monitors -The RAM detector unit will be housed in an environmentally suitable container that is mounted in a duct , on a wall , or other suitab l e surface. The sensitivity of each detector will be sufficient to have the alarm setpoint an order of magnitude higher than the detection threshold. The detectors are designed to be operational over a wide range of temperatures. The design of the detectors will meet expected normal and abnormal environmental design conditions , as appropriate. Saturation will not be expected to adversely affect operation of the detector within its calibrated range. Sensors will be mounted as close as practical to the most probable radiation sources with no objects , persons, pillars , and piping serving as shielding. The sensors will also be mounted so as to minimize inaccuracies due to any directionality of the detector.
A udible and vis ual alarm devices -When the radiation exceeds predetermined levels , alarms will actuate in the control room and at selected detector locations. 7-48
