Proprietary Information - Withheld from public disclosure under 10 CFR 2.390(a)(4)
Export Controlled Information - Withheld from public disclosure under 10 CFR 2.390(a)(3)
Chapter 4 - Irradiation Unit and Radioisotope Production Facility Description Subcritical Assembly 4a2.2.4.3 Source Strength The source is required to provide greater than 6.53.0E+056 neutrons per second (n/s).
4a2.2.4.4 Interaction with the System The placement of the source is inside of a stainless steel capsule that is located below the tritium target chamber. This capsule is accessible when the target chamber is removed and the source is able to be inserted and removed using long-handled tools.
4a2.2.4.5 Physical Environment The nominal temperature of the cooling water surrounding the source is approximately 68°F (20°C). The neutron source will be exposed to external neutron radiation up to [
]PROP/ECI and external gamma radiation up to [
]PROP/ECI.
4a2.2.4.6 Verification of Integrity and Performance Leak and contamination tests of the subcritical multiplication source are performed prior to use in the SHINE facility. Neutron strength measurements are made to ensure the stated activity prior to operation using the source.
4a2.2.4.7 Technical Specifications There are no technical specifications applicable to the subcritical multiplication source.
4a2.2.5 SUBCRITICAL ASSEMBLY SUPPORT STRUCTURE The TSV maintains the location and shape of the target solution during irradiation. The SASS positions the TSV relative to the neutron driver, neutron multiplier, subcritical multiplication source, and neutron flux detectors as shown in Figure 4a2.1-2. The SASS contains the TSV and supports TSV dump lines, TSV overflow lines, TOGS components, and associated instrumentation.
The SASS channels cooling water around the TSV and neutron multiplier. The PCLS is attached to the SASS upper and lower plenums. The PCLS forces cooling water to pass [
]PROP/ECI along the TSV inner and outer shells, and around the neutron multiplier to remove heat from the TSV and neutron multiplier during operation.
The SASS and PSB components are designed to withstand the design basis loads, including thermal, seismic, and hydrodynamic loads imposed by the light water pool during a seismic event. Hydrodynamic loads to safety-related equipment submerged within the light water pools were applied considering hydrodynamic added mass and drag forces from sloshing pool water.
These hydrodynamic loads were calculated using the maximum vertical displacement of sloshing pool water determined using the methods in Section 9 of ACI 350.3-06, Seismic Design of Liquid-Containing Concrete Structures and Commentary (ACI, 2006). In addition, the SASS and supported PSB components are designed to withstand normal operating loads imposed by the SHINE Medical Technologies 4a2.2-10 Rev. 5

Chapter 6 - Engineered Safety Features Nuclear Criticality Safety The mass of fissile material in the drums is controlled to less than the single parameter limit on uranium-235 mass. The mass is further restricted by waste acceptance limits on uranium-235 activity. A barrel which meets the waste acceptance limits meets the criticality safety limits.
Sample analysis of solution transferred to RLWI is performed and compared to previous sample results and verify uranium concentration is within the established limits. The proper amount of solidification agents is added to a barrel and weighed prior to transfer of uranium-bearing solution to the barrel to ensure waste acceptance limits are satisfied for downstream storage of the waste barrels within the material staging building.
Interaction between barrels is controlled by limiting the number of barrels present within the immobilization skid.
Precipitation of uranium requires application of the DCP to prevent criticality accidents. Reagent vessels have unique nozzle connections to prevent inadvertent transfer of reagents, and the volume of the vessels is limited. Process lines are sloped, and equipment are equipped with drains to prevent holdup of fissile material. Additionally, solutions transferred to the RLWI system undergo dual, independent sample analysis to verify the pH of the solution is within limits prior to transferring the solution.
6b.3.2.10 Laboratories The LABS receive, store, and process liquid and solid analytical samples of oxides, metals, and irradiated and unirradiated target solution.
The laboratory is controlled by an overall limit on mass which is significantly below the subcritical limit on mass for uranium-235 and is subcritical under all conditions.
Criticality Safety Basis The NCSE for the LABS shows that the entire process will remain subcritical under normal and credible abnormal conditions.
The LABS system is administratively controlled to ensure the combined total uranium mass is significantly below the subcritical mass for uranium-235.
6b.3.2.11 Material Staging Building The material staging building exists to process, characterize, and store byproduct material and SNM, used in the production of medical isotopes. The material staging building provides a location for the packaged radioactive material to decay until it can be transported to an off-site final disposal location. The material staging building will mostly store standard-sized 55-gallon drums containing cured, solidified waste. Other forms of radioactive waste are stored in the material staging building (e.g., used neutron drivers, glassware). Transient processing of column waste drums, including encapsulation and loading into appropriate shipping containers, also occurs in the material staging building. Column waste drums are not stored in the material staging building.

Chapter 6 - Engineered Safety Features Nuclear Criticality Safety Criticality Safety Basis The NCSE for the material staging building shows that the entire process will remain subcritical under normal and credible abnormal conditions.
The material stored in the material staging building is comprised entirely of exempt fissile material. To protect against damage to the material, the lift height of a barrel is limited so that if a barrel drop were to occur the barrel would remain undamaged. Solidified liquid waste meets the requirements for exemption from classification as fissile material under 10 CFR 71.15(c). As-generated solid waste meets the requirements for exemption from classification as fissile material under 10 CFR 71.15(a). Because the SNM stored in the material staging building is exempt fissile material and, there is no credible means of changing the state of the material, there is no need for additional controls. by which a criticality would occur.
Transient processing of column waste drums requires application of the DCP. The total non-exempt fissile material in a fissile material area is limited to 600 grams. Additionally, packages with non-exempt fissile material are limited to a maximum fissile material content of 50 grams.
6b.3.2.12 Iodine Extraction and Purification System The IXP is designed to separate iodine from irradiated uranyl sulfate target solution [
]PROP/ECI. The iodine is then purified into a sodium hydroxide solution. Xenon is collected from [
]PROP/ECI. The IXP is in a hot cell.
One operating line of the IXP is part of the RPF.
Criticality Safety Basis The NCSE for the IXP shows that the entire process will remain subcritical under normal and credible abnormal conditions.
The piping and equipment in the IXP containing target solution is favorable geometry within the single parameter limits. The IXP cell is equipped with a drain to RDS that is adequately sized to prevent buildup of solution in the cell.
The inadvertent transfer of target solution to the IXP eluate tank requires application of the DCP to prevent criticality accidents. A three-way valve is designed to prevent transfer of target solution to the eluate tank during extraction processing. Additionally, an isolation valve located between the three-way valve and eluate tank is administratively closed during processing of target solution.
Prevention of target solution backflow into the FCRS requires application of the DCP to prevent criticality accidents. A check valve is installed to prevent the flow of solution upstream to FCRS.
Additionally, an isolation valve located between the check valve and the FCRS is administratively closed during processing of target solution.
Precipitation due to inadvertent addition of caustic reagents requires application of the DCP to prevent criticality accidents. The IXP is equipped with unique nozzle hookups for each reagent to prevent improper FCRS hookups. Additionally, the wash sequence of the column is administratively controlled to prevent precipitation.

Chapter 7 - Instrumentation and Control Systems Summary Description NuScale Topical Report TR-1015-18653, Design of the Highly Integrated Protection System Platform (Nuscale, 2017), and is further described in Subsection 7.4.5.
7.1.5 CONTROL CONSOLE AND DISPLAYS The operator workstations and main control board are provided as the HSI subset of components for the FCR. These components are included as part of the PICS and are classified as nonsafety-related.
The two operator workstations provide operators with interactive displays to perform daily activities for the SHINE facility. The displays at the operator workstation are capable of being changed to the appropriate screen applicable to the activities that the operator is performing during day-to-day operations of the SHINE facility. Additional equipment, located between the two operator workstations and usable by either operator, is dedicated to controlling the eight NDAS units located in the IU cells.
The main control board, located in front of the two operator workstations, includes both digital displays and limited manual interfaces.
The main control board provides the operator with multiple digital displays, configured to continuously display variables important to safety-related system status for individual IUs and the balance of the SHINE facility. The displays on the main control board are used to support manual actuation of safety-related systems and to verify correct operation of the safety-related systems in the event of an actuation.
The main control board provides operator interfaces for:
- manual actuation of the TRPS and ESFAS protective functions,
- the enable nonsafety function, which allows PICS control of the actuation and priority logic (APL) output state (i.e., deenergized or energized), and
- the facility operating permissive key, which is used to place the main production facility into a secure state.
The supervisor workstation is located at the rear of the facility control room and acts as an extension of the operator workstations. The supervisor workstation is equipped with equipment display screens that allow the supervisor to monitor system status, but not and control facility components.
Facility controls are designed and located using consideration of human factors engineering principles. SHINE uses human factors engineering principles to facilitate the safe, efficient, and reliable performance of operations, maintenance, tests, inspections, and surveillance tasks, and to ensure the implementation of operator interfaces, indicators, and controls are standardized across vendors.
These systems are further described in Section 7.6.

Chapter 7 - Instrumentation and Control Systems Process Integrated Control System 7.3 PROCESS INTEGRATED CONTROL SYSTEM The SHINE facility is provided with nonsafety-related control systems necessary to perform normal operational activities within the facility. The process integrated control system (PICS) is a nonsafety-related digital control system that performs various functions throughout the SHINE facility. The PICS is the primary interface for operators to perform tasks in both the irradiation facility (IF) and the radioisotope production facility (RPF). PICS functions include signal conditioning, system controls, interlocks, and monitoring of the process variables and system status.
Vendor-provided nonsafety-related control systems, which interface and communicate with the PICS, are also present within the SHINE facility and are used to monitor and control specific facility systems.
The main control board and operator workstations in the facility control room are also part of the PICS and are described in Section 7.6.
7.3.1 SYSTEM DESCRIPTION The PICS is a collection of instrumentation and control equipment located throughout the facility to support monitoring, indication, and control of various systems. A portion of the PICS supports the main control board and operator workstations in the facility control room by receiving operator commands and collecting and transmitting facility information to the operators, as described in Section 7.6. The PICS system network routes signals to the main distribution switch located in the server room. Information from the facility control room, remote input/output cabinets, remote human machine interface panels, programmable logic controllers, vendor-provided control systems, and virtual machines communicates through the main distribution switch with a combination of copper cabling and fiber optic cabling. An architecture of the PICS is provided in Figure 7.3-1.
The following vendor-provided nonsafety-related control systems are also provided for the SHINE facility:
- The building automation system is a digital control system capable of integrating multiple building functions, including equipment supervision and control, alarm management, energy management, and trend data collection. It provides control for the facility heating water system (FHWS), the facility chilled water system (FCHS), the process chilled water system (PCHS), the radioisotope process facility cooling system (RPCS), facility ventilation zone 4 (FVZ4) air handling, and radiological ventilation zone 1, 2, and 3 (RVZ1/2/3) air handling. The building automation system receives commands from the PICS to start and stop select control sequences and provides information to the PICS for monitoring.
- The supercell contains a local control system and human system interface equipment for controlling hot cell functions including interior lighting, interior temperature and pressure, and operation of the doors, ports, and waste export system. The supercell control system provides information to PICS for monitoring only.
- The radioactive liquid waste immobilization (RLWI) system contains a local control system and human system interface equipment for controlling RLWI equipment functions including operation of equipment used to handle solidified waste. The RLWI control system provides information to PICS for monitoring only.

Chapter 7 - Instrumentation and Control Systems Process Integrated Control System active sequences. Components that are capable of being actuated by TRPS or ESFAS are controlled by PICS as described in Subsection 7.3.1.3.11.
When initiated by the operator, the PICS starts or stops the VTS by enabling or disabling the vacuum system pressure control loop.
The PICS automatically starts and stops the second of two VTS vacuum pumps to maintain vacuum system pressure within an allowable range.
The supercell control system is used by the operator to manually control hot cell (non-process) functions.
Interlocks and Permissives The PICS provides interlocks and permissives to:
- Close or prevent opening of individual VTS lift tank or target solution sample line vacuum valves when the corresponding VTS lift tank or target solution sample line high level switch signal is active.
- Close or prevent opening VTS vacuum buffer tank vacuum valves, and stop or prevent from starting the VTS vacuum pumps, and open the VTS vacuum buffer tank drain valve on high level in the VTS vacuum buffer tank.
- Close the VTS vacuum supply valves after being energized for a predetermined amount of time.
- Prevent the vacuum transfer sequence from starting if level in the destination tank selected is above an allowable limit.
- Prevent VTS vacuum pumps from starting if any buffer tank vacuum valve is open.
- Prevent VTS vacuum valves from energizing if PVVS flow is below an allowable limit.
Indication to the operator is provided on the PICS operator workstation displays when an interlock or permissive is bypassed.
7.3.1.2.6 Target Solution Staging System The TSSS is used in conjunction with the VTS (Subsection 7.3.1.2.5), and consists of hold tanks and storage tanks located in subgrade vaults. The TSSS is described in more detail in Subsection 4b.4.1.1.
Monitoring and Alarms The PICS monitors and provides alarms for two diverse methods of level indication for the individual TSSS tanks, and temperature indication for the individual TSSS tanks. The PICS additionally provides alarms when tank level or transfer time is outside of expected parameters during a solution transfer sequence.
Control Functions When manually initiated by the operator, the PICS executes a programmed sequence to transfer solution from one manually selected TSSS tank to another manually selected tank using the VTS. The PICS opens and closes the appropriate system isolation valves based on feedback SHINE Medical Technologies 7.3-15 Rev. 5
Chapter 7 - Instrumentation and Control Systems Process Integrated Control System The PICS directly monitors and provides alarms for battery room and UPS equipment room temperatures, battery room hydrogen concentration, battery charge level, battery charger current, inverter bypass status, inverter current, and various other system parameters for both divisions of the UPSS. The PICS also provides alarms for fault conditions of UPSS components (e.g., battery fault, battery charger fault, UPS fault, DC bus ground) and unexpected system alignments (e.g., battery charger breakers open, bypass transformer breakers open, inverter bypass breaker closed, load breakers open).
Control Functions None Interlocks and Permissives None 7.3.1.4.3 Standby Generator System The SGS provides nonsafety-related backup power for the SHINE facility, as described in Subsection 8a2.2.6. The SGS generator includes a vendor-provided nonsafety-related controller.
Monitoring and Alarms The PICS provides monitoring and alarms for SGS voltage, current, and power. The internal vendor-provided SGS generator controller additionally monitors for generator status and faults, including oil pressure, water temperature, engine temperature, fuel pressure, coolant level, overcrank or overspeed conditions, and other generator parameters. The SGS controller provides a subset of these monitored parameters to the PICS for display and alarming.
Control Functions The PICS provides the operator the ability to manually start or stop the generator by providing a signal to the SGS automatic transfer switch(es), and to manually transfer loads between the generator and the off-site utility by opening and closing breakers.
The SGS generator controller automatically starts the generator in response to a loss of off-site power event. PICS automatically sequences the loads onto the generator.
Interlocks and Permissives The generator automatic transfer switch design prevents paralleling the generator with either service entrance.
7.3.1.4.4 Nitrogen Purge System The nitrogen purge system (N2PS) provides a backup supply of sweep gas to each IU and to all tanks normally ventilated by the PVVS during a loss of normal power or loss of normal sweep gas flow. The off-gas resulting from the nitrogen purge is treated by passive PVVS equipment prior to being discharged to the alternate vent path in the PVVS and the stack. The N2PS is described in Subsections 6b.2.3 and 9b.6.2.

Chapter 7 - Instrumentation and Control Systems Process Integrated Control System PICS Criterion 3 - The PICS software development lifecycle process requirements shall be described and documented in appropriate plans which shall address verification and validation (V&V) and configuration control activities.
The PICS is developed in accordance with the PICS validation master plan, which addresses V&V and configuration control activities, as described in Subsection 7.3.3.4. The development of other vendor-provided nonsafety-related control systems is also described in Subsection 7.3.3.4.
PICS Criterion 4 - The configuration control process shall assure that the required PICS hardware and software are installed in the appropriate system configuration and ensure that the correct version of the software/firmware is installed in the correct hardware components.
The PICS validation master plan assures that the required PICS hardware and software are installed in the appropriate system configuration and ensures that the correct version of the hardware/firmware is installed in the correct hardware components as described in Subsection 7.3.3.4. Configuration control of other vendor-provided nonsafety-related control systems is also described in Subsection 7.3.3.4.
7.3.2.2.3 Fail Safe PICS Criterion 5 - The PICS shall assume a defined safe state with loss of electrical power to the PICS.
Components controlled by the PICS assume a defined safe state on loss of electrical power (Subsection 7.3.3.6).
7.3.2.2.4 Effects of Control System Operation/Failures PICS Criterion 6 - The PICS shall be designed so that it cannot fail or operate in a mode that could prevent the TRPS or ESFAS from performing its designated functions.
Nonsafety-related PICS inputs into the TRPS and ESFAS are designed and controlled so they do not prevent the TRPS or ESFAS from performing its safety functions as described in Subsections 7.4.3.4 and 7.5.3.3. Other vendor-provided nonsafety-related control systems do not provide input to the TRPS or ESFAS.
The failure modes and effects analysis for the TRPS and ESFAS (Subsection 7.4.5.2.2) evaluates the interfaces with PICS for any direct impacts and ensures that no failures within the PICS could directly impact the ability of the TRPS or ESFAS to perform its functions.
To assess whether PICS could indirectly affect the ability of the TRPS or ESFAS to perform its functions or any other control credited in the SHINE Safety Analysis (Section 13a2) from being performed, a review of monitored variables within the TRPS and the ESFAS and credited controls is performed. The assessment includes an evaluation of whether any condition could exist in the facility, caused by the failure of one or more PICS-controlled components, that could:
(1) cause an unsafe condition to exist but the system not to see it, or (2) could interfere with a safety function being completed. The assessment identifies the necessary design controls to ensure that PICS could not indirectly affect the ability of the TRPS or ESFAS from performing its functions or a credited control in the SHINE Safety Analysis from being performed.

An IU Cell Safety Actuation causes a transition of the TRPS to Mode 3 operation, isolation of the primary system boundary, and isolation of the primary confinement boundary via transition of each of the following components to their deenergized state.
Mode 3 Transition Components
- TSV dump valves
- NDAS high voltage power supply (HVPS) breakers Primary System Boundary Components
- TSV fill isolation valves
- TSV dump tank drain isolation valve
- TOGS gas supply isolation valves

- High source range neutron flux
- High time-averaged neutron flux*
- High wide range neutron flux
- High RVZ1e IU cell radiation SHINE Medical Technologies 7.4-20 Rev. 5

Target Solution Vessel Chapter 7 - Instrumentation and Control Systems Reactivity Protection System
- High TOGS condenser demister outlet temperature (Train B)
- ESFAS loss of external power 7.4.3.1.3 IU Cell TPS Actuation An IU Cell TPS Actuation is initiated when monitored variables indicate a release of tritium in a TPS glovebox, within the IU cell, or within the TPS IU cell supply/exhaust lines. An IU Cell TPS Actuation results in isolating the TPS lines into and out of the IU cell, isolating the RVZ1 exhaust out of the IU cell, and deenergizing the neutron driver.
An IU Cell TPS Actuation consists of an automatically or manually initiated transition of each of the following components to their deenergized state and initiating a Driver Dropout (see Subsection 7.4.3.1.4):
- TPS target chamber supply isolation valves
- TPS deuterium supply isolation valves
- TPS target chamber exhaust isolation valves
- TPS neutron driver evacuation isolation valves
- RVZ1e IU cell isolation valves The TRPS initiates an IU Cell TPS Actuation based on the following variables:
- ESFAS IU Cell TPS Actuation
- ESFAS TPS Process Vent Actuation
- Facility master operating permissive 7.4.3.1.4 Driver Dropout A Driver Dropout responds to monitored variables that indicate a loss of neutron driver output or a loss of cooling to allow the SCAS to recover from NDAS or PCLS transients. A Driver Dropout functions differently depending on whether it was initiated based on loss of neutron driver output or loss of cooling.
A Driver Dropout is relied upon as a safety-related control for insertion of excess reactivity events (Subsection 13a2.1.2, Scenario 4), and reduction in cooling events (Subsection 13a2.1.3, Scenarios 1 and 2). The TRPS initiates a Driver Dropout based on:
- Low power range neutron flux
- Low PCLS flow
- High PCLS temperature
- IU Cell TPS Actuation
- Facility master operating permissive The TRPS initiates a loss of neutron driver Driver Dropout on low power range neutron flux by opening the NDAS HVPS breakers with a timed delay. Driver Dropout on low power range neutron flux is bypassed until the power range neutron flux has reached the power range driver dropout permissive. After the bypass of Driver Dropout on low power range neutron flux has been removed, it remains removed until a mode transition or both HVPS breakers are open. The TRPS implements a timed delay of [ ]PROP/ECI from the time the low power range neutron flux signal is initiated, indicating that the neutron flux has exceeded its lower limits, to SHINE Medical Technologies 7.4-22 Rev. 5
Target Solution Vessel Chapter 7 - Instrumentation and Control Systems Reactivity Protection System when the TRPS output to the HVPS breakers is deenergized. If fewer than two-out-of-three low power range neutron flux actuation signals are present before the timer has expired, then the low power range neutron flux timer resets. This delay allows the neutron driver to be restarted or to restart automatically within analyzed conditions.
The TRPS initiates a loss of cooling Driver Dropout on low PCLS cooling water flow or high PCLS cooling water supply temperature to open the NDAS HVPS breakers without a timed delay. This shuts down the neutron driver to prevent overheating of the target solution, while allowing the target solution to remain within the TSV. The breakers are then interlocked open until the PCLS flow and temperature are in the allowable range. If PCLS flow and temperature are not in the allowable range within 180 seconds, an IU Cell Safety Actuation is initiated, as described in Subsection 7.4.3.1.1.
7.4.3.2 Mode Transition The design of the TRPS includes use of permissives and interlocks to control transition between IU operating modes to ensure safe operation of the main production facility. IU operating modes are described in Subsection 7.3.1.1.
Each mode transition in the TRPS is initiated manually through the PICS; however, transition to Mode 3 can occur automatically by an IU Cell Safety Actuation or by use of the control key to deactivate the facility master operating permissive. Before an operator is able to manually transition to a different mode, the transition criteria conditions must be met. Figure 7.4-1 shows a state diagram of the mode transitions.
Mode 0 to Mode 1 Transition Criteria The TRPS permissives prevent transitioning from Mode 0 to Mode 1 until theboth TSV dump valves and at least one TSV fill isolation valves have been confirmed to be closed and TOGS mainstream flow is at or above the low flow limit. Normal control of actuation component positions when going from Mode 0 to Mode 1 is manual and independent from TRPS mode transition.
Mode 0 to Mode 3 Transition Criteria Transition from Mode 0 to Mode 3 is initiated automatically by TRPS or manually by an operator via manual actuation or the facility master operating permissive (Subsection 7.4.4.2). Initiation of this transition generates an IU Cell Safety Actuation.
Mode 1 to Mode 2 Transition Criteria The TRPS permissives prevent transitioning from Mode 1 to Mode 2 until theat least one TSV fill isolation valves indicates fully closed. Normal control of actuation component positions when going from Mode 1 to Mode 2 is manual and independent from TRPS mode transition.
Mode 1 to Mode 3 Transition Criteria Transition from Mode 1 to Mode 3 is initiated automatically by TRPS or manually by an operator via manual actuation or the facility master operating permissive (Subsection 7.4.4.2). Initiation of this transition generates IU Cell Safety Actuation.
SHINE Medical Technologies 7.4-23 Rev. 5
Target Solution Vessel Chapter 7 - Instrumentation and Control Systems Reactivity Protection System 7.4.4.1.13 High TOGS Condenser Demister Outlet Temperature The high TOGS condenser demister outlet temperature signal protects against adverse effects on TOGS instrumentation and zeolite beds, causing them to fail to perform their safety functions (Subsection 13a2.1.9.2, Scenario 1). The signal is generated by TRPS when a TOGS condenser demister outlet temperature input exceeds the high level setpoint. TOGS condenser demister outlet temperature is measured independently for both TOGS Train A and TOGS Train B. The TOGS condenser demister outlet temperature signal is measured with a temperature interface on three different channels, one for each TRPS division. When two-out-of-three or more TOGS condenser demister outlet temperature inputs exceed the allowable limit, an IU Cell Safety Actuation and an IU Cell Nitrogen Purge are initiated.
7.4.4.1.14 ESFAS Loss of External Power The ESFAS loss of external power signal is an anticipatory protection against the impending loss of TOGS blowers and recombiners after the runtime of that equipment on the UPSS has been exceeded (Subsection 13a2.1.9.2, Scenario 1). The signal is generated by ESFAS and provided to each of the eight TRPS subsystems when ESFAS senses a loss of external (i.e., normal) power being provided to the UPSS as described in Subsection 7.5.4.1.19. TRPS does not receive the loss of external power signal from ESFAS until three minutes after the external power loss. The ESFAS loss of external power signal is measured with a discrete input signal on two different channels, one for each Division A and Division B of TRPS. When an ESFAS loss of external power signal indicates power has been lost, the division receiving the discrete signal initiates an IU Cell Nitrogen Purge.
7.4.4.1.15 High RVZ1e IU Cell Exhaust Radiation The high RVZ1e IU cell exhaust radiation signal protects against a breach in the primary system boundary (Subsection 13a2.1.4.2, Scenario 4; and Subsection 13a2.1.9.2, Scenario 2). The high RVZ1e IU cell exhaust radiation is measured on the exhaust of the PCLS expansion tank located in each IU cell. The signal is generated by TRPS when an RVZ1e IU cell exhaust radiation input exceeds the high level setpoint. The RVZ1e IU cell radiation is measured with an analog interface on three different channels, one for each division of TRPS. When two-out-of-three or more RVZ1e IU cell exhaust radiation channels exceed the allowable limit, an IU Cell Safety Actuation is initiated.
7.4.4.1.16 TSV Fill Isolation Valve Position Indication Not Closed A TSV fill isolation valve position indication not closed signal protects against the inadvertent addition of target solution to the TSV (Subsection 13a2.1.2.2, Scenario 6) via an inappropriately opened TSV fill isolation valve. The TSV fill isolation valve position indication is received by the TRPS as a discrete input from redundant position indicating limit switches on two different channels for each valve. When one-out-of-two or more TSV fill isolation valve position indication signals indicate the associated valve is not closed for eitherboth of the TSV fill isolation valves, an IU Cell Safety Actuation is initiated. IU Cell Safety Actuation on TSV fill isolation valve position indication is only applicable when the IU cell is undergoing irradiation (Mode 2).
SHINE Medical Technologies 7.4-34 Rev. 5
Target Solution Vessel Chapter 7 - Instrumentation and Control Systems Reactivity Protection System associated SBVMs within the division. When associated permissives are satisfied and the manual operator action for mode transition occurs, the TRPS progresses to the next mode and the SBVMs will: (1) automatically bypass the final trip determinations for safety actuations that are not required for that particular mode of operation, and (2) will automatically remove any bypasses of the final trip determinations for safety actuations that are required for that particular mode of operation. See the TRPS mode state diagram in the TRPS logic diagrams (Figure 7.4-1) for the transitional sequence of the TRPS.
If the permissive conditions are not met for transitioning to the next mode and the operator action occurs, the TRPS will not advance to the next mode of operation. Below are the required conditions that must be satisfied before a transition to the following mode in the sequence can be initiated.
- The TRPS shall only transition from Mode 0 to Mode 1 if all TSV dump valve position indications indicate valves are fully closed and all TSV fill isolation valve position indications indicate at least one valve is are fully closed and the TOGS mainstream flow is above the minimum flow rate.
- The TRPS shall only transition from Mode 1 to Mode 2 if the TSV fill isolation valve position indications indicate both at least one valve is are fully closed.
- The TRPS shall only transition from Mode 2 to Mode 3 if all HVPS breaker position indications indicate the breakers are open.
- The TRPS shall only transition from Mode 3 to Mode 4 if an IU Cell Safety Actuation is not present.
- The TRPS shall only transition from Mode 4 to Mode 0 if the TSV dump tank level is below the low-high TSV dump tank level.
In each mode of operation, the TRPS bypasses different actuation channels when the actuation channel is not needed for initiation of an IU Cell Safety Actuation, an IU Cell Nitrogen Purge, an IU Cell TPS Actuation, or Driver Dropout. The lists below identify each variable that is bypassed during the different modes of operation.
Safety actuations based on the following instrumentation channels are bypassed in Mode 0:
- Low power range neutron flux
- Low PCLS temperature
- High PCLS temperature
- Low PCLS flow
- Low TOGS mainstream flow (Train A) (Train B)
- Low TOGS dump tank flow
- High TOGS condenser demister outlet temperature (Train A) (Train B)
- ESFAS loss of external power
- TSV fill isolation valve position indication not closed Safety actuations based on the following instrumentation channels are bypassed in Mode 1:
- Low power range neutron flux
- TSV fill isolation valve position indication not closed
- Low PCLS flow
- High PCLS temperature SHINE Medical Technologies 7.4-36 Rev. 5

Chapter 7 - Instrumentation and Control Systems Neutron Flux Detection System The NFDS provides continuous indication of the neutron flux from zero counts per second (cps) to at least 250 percent power with twoone decades of overlap (Subsection 7.8.3.1).
NFDS Criterion 3 - The NFDS power range channels shall provide reliable TSV power level while the source range channel provides count rate information from detectors that directly monitor the neutron flux.
The NFDS power range provides a signal proportional to TSV power level from 0 to 125 percent of the licensed power limit. The source range provides a current signal proportional to count rate for all expected startup count rates (Subsection 7.8.3.1).
NFDS Criterion 4 - The NFDS log power range channel (i.e., wide range channel) and a linear flux monitoring channel (i.e., power range channel) shall accurately sense neutrons during irradiation, even in the presence of intense high gamma radiation.
Each NFDS division includes an ionization chamber detector and a Boron Trifluoride (BF3)fission chamber detector pair. These detector types are primarily sensitive to thermal neutrons.
NFDS Criterion 5 - The NFDS shall provide redundant TSV power level indication through the licensed maximum power range.
The NFDS is comprised of three redundant divisions of detectors, preand NFDS amplifiers, and processing circuits for single failure protection (Subsection 7.8.3.3). The wide range neutron flux monitors percent power up to 250 percent of the licensed power limit (Subsection 7.8.3.1.3). The power range neutron flux signal has a range of 0 percent to 125 percent of the licensed power limit (Subsection 7.8.3.1.2).
NFDS Criterion 6 - The location and sensitivity of at least one NFDS detector in the source range channel, along with the location and emission rate of the subcritical multiplication source, shall be designed to ensure that changes in reactivity will be reliably indicated even with the TSV shut down.
The positioning of the NFDS source range detectors, and the location, and emission rate of the subcritical multiplication source, is designed so that all three channels are on scale throughout filling. This includes while the TSV is empty of solution. NFDS source range signal increases with increasing target solution volume, and in this way, increasing reactivity will always produce an increase in count rate.
NFDS Criterion 7 - The NFDS shall have at least one detector in the power range channel to provide reliable readings to a predetermined power level above the licensed maximum power level.
The wide range neutron flux monitors percent power up to 250 percent of the licensed power limit (Subsection 7.8.3.1.3). The power range neutron flux signal has a range of 0 percent to 125 percent of the licensed power limit (Subsection 7.8.3.1.2).
NFDS Criterion 8 - The NFDS shall be separated from the PICS to the extent that any removal of a component or channel common to both the NFDS and the PICS preserves the reliability, redundancy, and independence of the NFDS.
SHINE Medical Technologies 7.8-5 Rev. 4
Chapter 7 - Instrumentation and Control Systems Neutron Flux Detection System The power range neutron flux signal has a range of 0 percent to 125 percent of the licensed power limit and has an accuracy of less than or equal to 1 percent of the full linear scale.
7.8.3.1.3 Wide Range The wide range neutron flux connects the gap between the source range and the power range with overlap and is usable during both source and power range levels. The wide range neutron flux monitors percent power up to 250 percent of the licensed power limit.
The NFDS transmits the following wide range analog signals to the TRPS:
- NFDS wide range The NFDS wide range neutron flux signal is input to the safety-related trip determination by the TRPS. The TRPS initiates an IU Cell Safety Actuation on high wide range neutron flux, as described in Subsection 7.4.4.
The wide range neutron flux signal has an accuracy of less than or equal to 1 percent of the full logarithmic scale.
7.8.3.2 Simplicity The NFDS is an analog system with no digital communications for simplicity. In the source range, the NFDS provides voltage pulses corresponding to pulses from the associated fission chamber detector. In the wide range and power range, the signal from the compensated ion chambers is input to log and linear amplifiers corresponding to the neutron flux and is output to the TRPS as a 0 to 4 volt signal. Communications from the NFDS to the TRPS and PICS (via TRPS) are continuous through isolated outputs. The output isolation devices only allow for the data to be transmitted out of the system so that no failure from an interfacing system can affect the functions of the NFDS.
7.8.3.3 Single Failure The NFDS is comprised of three redundant divisions of detectors, preand NFDS amplifiers, and processing circuits. A single failure of any one of the divisions will not affect the functionality of the other two redundant divisions ensuring the required safety functions perform as designed during a design basis event. There are no shared signals from the NFDS that have both a TRPS safety-related protection function and a nonsafety-related control function. Failures of nonsafety-related systems do not impact the NFDS from performing its safety function.Interfacing systems with the NFDS are downstream of the NFDS such that a failure of an interfacing nonsafety system will not impact the NFDS.
7.8.3.4 Independence The three divisions of the NFDS are physically and electrically independent of each other.
Detectors are installed approximately 120 degrees equidistant around the SASS in relation to the target solution vesselTSV. The detector cables are routed back to the TRPS electronics in physically separated electronics enclosures.

(a) Management personnel, (b) Radiation safety personnel, and (c) Other operations personnel.
Staffing requirements are included in the technical specifications.
The role of the operator in the SHINE facility is to perform the manual actions required to safely and efficiently manufacture medical isotopes. There are no postulated accident sequences that credit operator action to mitigate the consequences of the event after initiation of the event.
Should an initiating event of a postulated accident sequence occur, operator actions provide a defense-in-depth, nonsafety-related, diverse means of actuating components.
12.1.4 SELECTION AND TRAINING OF PERSONNEL SHINE establishes and maintains training programs for personnel performing, verifying, or managing facility operation activities to ensure that suitable proficiency is achieved and maintained. The Training Manager (TM) reports to the Director of Corporate Support (DCS) and is responsible for development and implementation of training that ensures satisfactory operational behavior and performance in the areas of nuclear, industrial, and radiological safety.
American National Standards Institute/ American Nuclear Society (ANSI/ANS) 15.4-2016 is used in the selection and training of personnel (ANSI/ANS, 2016a). Records of personnel training and qualification are maintained.
In general, operations personnel have the combination of academic training, job-related experience, health, and skills commensurate with their level of responsibility that provides reasonable assurance that decisions and actions during normal and abnormal conditions are SHINE Medical Technologies 12.1-3 Rev. 3
Chapter 12 - Conduct of Operations Organization 12.1.4.1 Initial Training and Requalification The licensed operator training program, including the requalification training program, is implemented in accordance with 10 CFR Part 55 as it pertains to non-power facilities and the guidance provided in ANSI/ANS 15.4-2016 (ANSI/ANS, 2016a). The SHINE facility operator training and requalification programs are described in Section 12.10.
12.1.4.2 10 CFR Part 19 Training Individuals whose assigned duties involve exposure to radiation or radioactive material, and in the course of their employment are likely to receive, in a year, an occupational dose of radiation greater than 100 millirem (mrem) (1 millisievert [mSv]), receive instruction commensurate with their duties and responsibilities, as required by 10 CFR 19.12.
The design and implementation of the radiation protection training program complies with the requirements of 10 CFR 19.12.
12.1.5 RADIATION SAFETY The RPP is described in greater detail in Subsection 11.1.2. The RPP meets the requirements of 10 CFR Part 20, Subpart B, and is consistent with the guidance provided in Regulatory Guide 8.2, Revision 1, Administrative Practices in Radiation Surveys and Monitoring, and ANSI/ANS 15.11-2016, Radiation Protection at Research Reactor Facilities (ANSI/ANS, 2016b).
Development and implementation of the RPP is commensurate with the risks posed by a medical isotope production facility. Procedures and engineering controls are based upon sound RP principles to achieve occupational doses to on-site personnel and doses to members of the public that are as low as reasonably achievable (ALARA).
The organizational structure and responsibilities, including the radiation safety function, are described in Sections 12.1.1 and 12.1.2.
The RP Department is independent of facility operations. This independence ensures that the RP Department maintains its objectivity and is focused only on implementing sound RP principales necessary to achieve occupational doses and doses to members of the public that are ALARA.
RP staff maintain the ability to raise safety issues with the review and audit committee or executive management. The RP staff encompasses the clear responsibility and ability to interdict or terminate licensed activities that it believes are unsafe. This does not mean that the RP staff possesses absolute authority. If facility managers, the review and audit committee, and executive management agree, the decision of the RP staff could be overruled. However, this would be a rare occurrence that would be carefully analyzed and considered.
12.1.6 NUCLEAR SAFETY PROGRAM The production facility safety program is implemented within the nuclear safety program and developed using methodologies as described in Interim Staff Guidance Augmenting NUREG-1537, Part 1, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors: Format and Content, for Licensing Radioisotope Production Facilities and Aqueous Homogeneous Reactors (USNRC, 2012a); and Interim Staff Guidance Augmenting SHINE Medical Technologies 12.1-5 Rev. 3
Chapter 12 - Conduct of Operations Review and Audit Activities 12.2 REVIEW AND AUDIT ACTIVITIES The Diagnostics General Manager (DGM) establishes the review and audit committee and ensures that the appropriate technical expertise is available for review and audit activities. The DGM holds approval authority for review and audit activities. Independent audits of the SHINE facility are conducted periodically.
The review and audit committee will interact with facility management through the dissemination of meeting minutes and meeting reports. SHINE will submit a written report or minutes of the findings and recommendations of the review group to Level 1 management and the review and audit group members in a timely manner after the review has been completed. SHINE will immediately report deficiencies uncovered that affect nuclear safety to Level 1 management.
12.2.1 COMPOSITION AND QUALIFICATIONS The review and audit committee shall have the appropriate expertise and experience such that members provide the SHINE management an independent assessment of the operation. The DGM or designee chairs the review and audit committee and appoints additional members. The minimum number of the members shall be three. The qualifications for the review and audit committee members shall include a broad spectrum of technical, operational, and managerial expertise. At a minimum, the committee shall include members with expertise in facility operations, engineering, and radiation protection. Non-SHINE employees may be appointed as committee members, at the discretion of the chair. Assignment of non-SHINE employees to the committee will be necessary in circumstances when the required expertise to perform an activity is not available from SHINE employees (e.g., to perform an audit of an area where the only personnel with expertise in that area are immediately responsible for that area).
12.2.2 CHARTER AND RULES The charter for the review and audit committee requires at least one meeting per year, with a quorum being a minimum of 50 percent of the voting committee membership where the facility operationg staff s personnel does not constitute a majority. Facility operations personnel consist of all facility personnel organizationally subordinate to, and including, the Director of Plant Operations (DPO). Dissemination, review, and approval of minutes shall occur within three months. The review and audit committee charter shall include provisions for the use of subgroups. Committee reports and reviews shall be distributed by memorandum to Level 1 management and other management as designated in the charter. Voting may be conducted at the meeting or by polling members with a majority required for approval.
12.2.3 REVIEW FUNCTION At a minimum, the following items shall be reviewed:

SUMMARY
PUBLIC VERSION PHASED STARTUP OPERATIONS APPLICATION SUPPLEMENT MARKUP
Chapter 7 - Instrumentation and Control Systems Individual inputs to the ESFAS are disabled using the maintenance workstation (MWS).
Physically, this process occurs in a similar manner to modifying a setpoint with the MWS. The technician performing the modification accesses the MWS with a password, selects the ESFAS, the division, the specific safety function module (SFM), and the individual input to be disabled.
The technician then activates a hardwired switch near the MWS to allow for physical connection of the MWS to the calibration and test bus (CTB). The technician then toggles the input disable switch on the MWS that indicates the individual input is disabled. The technician asserts the disable function to complete disabling of the individual input. The disable status associated with the disabled input is stored in a location on the SFMs non-volatile memory (NVM). The NVM location is loaded to the triplicated logic designs on the field programmable gate array (FPGA) during startup or a manual NVM data load command from the modules front panel switch. The SFMs safety function logic is independent (i.e., different logic resources on the FPGA) from both the logic used to store information to the NVM and the logic used to load information from the NVM to the safety function logic.
Individual inputs for each safety actuation not required to be operable and that would prevent facility operation in a given phase are disabled across all divisions. The disabling of these inputs causes the ESFAS to not process them as an actuation request, and hence, does not initiate unnecessary protection actions based upon them. The MWS continues to function as described in Subsection 7.4.5.3.3 of the FSAR. Information for inputs that are disabled will be transmitted to the PICS and displayed to the operator as described in Section 7.6.3.
The TRPS IU Cell 1/2/3/4/5/6/7/8 Nitrogen Purge signals are actuation signals that are transmitted from the TRPS to the ESFAS. Because these signals are not transmitted into the appropriate SFMs but rather the schedule, voting, and bypass modules (SBVMs), there is no ability to disable the inputs. However, these signals are not asserted for TRPS instances that are not applicable to a phase of operation.
The modification to the generic HIPS platform to disable individual inputs does not impact how the TRPS and ESFAS satisfy application specific action items (ASAIs) 24 and 54 described in the HIPS topical report Safety Evaluation Report (SER) (USNRC, 2017) or how the TRPS and ESFAS comply with IEEE Standard 7-4.3.2-2003 (IEEE, 2003), as described in Subsection 7.4.5.1 of the FSAR.
The HIPS design attributes provided in Subsection 7.4.5.2 of the FSAR are not affected by phased startup operations. Since the TRPS is being implemented in instances associated with individual IUs, the HIPS design is being implemented in full for each instance. The disabling of individual inputs to the ESFAS do not impact the independence, redundancy, and diversity of the ESFAS in a given phase. No new failure modes are introduced by disabling individual inputs, so the failure modes and effects analysis (FMEA), diversity and defense-in-depth assessment, and single failure analysis are not affected. The descriptions of independence, redundancy, predictability and repeatability, diversity, and simplicity provided in Subsection 7.4.5.2 of the FSAR are not affected by phased startup operations. The HIPS platform timing shown in Figure 7.4-2 of the FSAR is not affected by phased startup operations.
The access control and cyber security considerations provided in Subsection 7.4.5.3 of the FSAR are not affected by phased startup operations.
The software requirements development considerations provided in Subsection 7.4.5.4 of the FSAR are not affected by phased startup operations. For cabinets not in operation, implementation and verification of the appropriate software version occurs during the testing SHINE Technologies 7-6 Rev. 01

Additional discussion for each variable listed in Table 3.7.1-a is provided below:
- a. The supercell PVVS hot cell contains equipment for the PVVS and VTS, which contain fission product gases. The RVZ1 supercell area 1 radiation monitors provide an actuation signal that isolates the affected hot cell and initiates a VTS Safety Actuation to minimize the spread of radioactive material, as described in FSAR Subsection 7.5.4.1.2. The setpoint of 7.6E-05 µCi/cc considers instrument uncertainties and provides margin to an analytical limit of 1.2E-04 µCi/cc. Three channels of radiation monitoring are provided.

The RVZ1 supercell exhaust ventilation (PVVS hot cell) channels may be rendered temporarily inoperable in accordance with LCO 3.0.1.4 to facilitate resetting ESFAS and restoring the RVZ1 system to normal operations.
- b. The supercell extraction and IXP hot cells periodically contain irradiated target solution. The RVZ1 supercell area 2/6/7/10 radiation monitors provide an actuation signal that isolates the affected hot cell to minimize the spread of radioactive material, as described in FSAR Subsections 7.5.4.1.3 and 7.5.4.1.4. The setpoint of 7.6E-05 µCi/cc considers instrument uncertainties and provides margin to an analytical limit of 1.2E-04 µCi/cc. Two channels of radiation monitoring are provided per area.

- d. The RVZ1 RCA exhaust location is monitored for elevated radiation originating from RVZ1 spaces, including the supercell and the PCLS expansion tanks, which communicate with the IU cell atmospheres. The RVZ1 RCA exhaust radiation monitors provide an actuation signal that performs an RCA Isolation to minimize the spread of radioactive material, as described in FSAR Subsection 7.5.4.1.1. The setpoint of 1.3E-05 µCi/cc considers instrument uncertainties and provides margin to an analytical limit of 1.9E-05 µCi/cc. Three channels of radiation monitoring are provided.

- e. The RVZ2 RCA exhaust location is monitored for elevated radiation originating from RVZ2 spaces, which include the general area of the Page B 3.7-7 Revision 6
Proprietary Information - Withheld from public disclosure under 10 CFR 2.390(a)(4)
Export Controlled Information - Withheld from public disclosure under 10 CFR 2.390(a)(3) irradiation facility (IF) and RPF. The RVZ2 RCA exhaust radiation monitors provide an actuation signal that performs an RCA Isolation to minimize the spread of radioactive material, as described in FSAR Subsection 7.5.4.1.1.
The setpoint of 9.1E-07 µCi/cc considers instrument uncertainties and provides margin to an analytical limit of 1.4E-06 µCi/cc. Three channels of radiation monitoring are provided.
With one channel inoperable the SFM for the associated channel is placed in trip within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and must be restored to Operable within 30 days72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

- f. The RVZ1e IU cell exhaust location is monitored for elevated radiation in the PCLS or IU cell atmosphere for each IU. The RVZ1e IU cell radiation monitors provide an actuation signal that results in an IU Cell Safety Actuation to minimize the spread of radioactive material, as described in FSAR Subsection 7.4.4.1.15. The setpoint of 9.6E-03 µCi/cc considers instrument uncertainties and provides margin to an analytical limit of 1.5E-02 µCi/cc. Three channels of radiation monitoring are provided per IU.
With one channel inoperable the SFM for the associated channel is placed in trip within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and must be restored to Operable within 30 days72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
With fewer than two required channels Operable, the associated IU is placed in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> by automatic or manual transitions. At least one RVZ1e IU cell ventilation damper for the associated IU cell is also required to be closed within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. This completion time allows for the performance of minor repairs and allows for the affected IU to be shut down or the affected processes to be halted in an orderly manner. The completion time is acceptable based on the continued availability of the redundant TRPS Division(s) to sense adverse conditions and actuate equipment in response to an event. Transfer of target solution out of the IU to achieve Mode 0 requires the target solution to be held in the TSV dump tank for at least the minimum period of time specified in LCO 3.1.8 prior to transfer. Approximately [
]PROP/ECI are required to complete the transfer of target solution to the RPF.
The RVZ1e IU cell exhaust channels may be rendered temporarily inoperable in accordance with LCO 3.0.1.4 to facilitate resetting TRPS and restoring the RVZ1e system to normal operations.
- g. The TPS confinement A, B, and C atmospheres are monitored for tritium.
There is normally a low tritium concentration on the order of less than 1 mCi/m3 in the TPS glovebox due to process equipment leakage and tritium permeation. The TPS glovebox tritium concentration setpoint of 927 Ci/m3 considers instrument uncertainties and is based on an analytical limit of Page B 3.7-8 Revision 6
1000 Ci/m3. A tritium concentration in excess of this limit is indicative of excessive amounts of tritium leaking from TPS process equipment, as described in FSAR Subsection 7.5.4.1.13. The radiation monitors provide an actuation signal that isolates the associated glovebox and ventilation of the TPS room to minimize the spread of radioactive material. Two channels of radiation monitoring are provided.
With fewer than two required channels Operable, tritium is required to be returned to its storage location within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (i.e., a depleted uranium bed) or at least one redundant TPS Train Isolation device per associated TPS glovebox confinement flow path is closed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to provide the isolation function. A completion time of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allows for the performance of minor repairs and is acceptable based on the low likelihood of a tritium release during the allowed time.
The TPS confinement A/B/C channels may be rendered temporarily inoperable in accordance with LCO 3.0.1.4 to facilitate resetting ESFAS and restoring the associated TPS train to normal operations.
- h. The TPS exhaust to the facility stack is monitored for tritium. The TPS secondary enclosure cleanup (SEC) normally reduces tritium concentrations that enter RVZ1e to less than 10 µCi/m3. The TPS exhaust to the facility stack tritium concentration setpoint of 0.96 Ci/m3 considers instrument uncertainties and is based on an analytical limit of 1 Ci/m3. A tritium concentration in excess of this limit is indicative of a malfunction of the TPS or a tritium release, as described in FSAR Subsection 7.5.4.1.12. The radiation monitors limit the spread of tritium throughout and outside the facility via the ventilation system by providing an actuation signal that isolates the potential release paths to the facility stack from all three TPS gloveboxes via a TPS Process Vent Actuation. Three channels of radiation monitoring are provided.
With one channel inoperable, the SFM for the associated channel is placed in trip within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and must be restored to Operable within 30 days72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
With two or three required channels inoperable, tritium is required to be returned to its storage location within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (i.e., a depleted uranium bed) or at least one redundant TPS Process Vent Actuation device per TPS exhaust flow path is closed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to provide the isolation function. A completion time of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allows for the performance of minor repairs and is acceptable based on the low likelihood of a tritium release during the allowed time.
- i. The ESFAS monitors radiation in the MEPS heating water loop to protect against a leakage of high radiation solutions into the MEPS hot water heating loops, as described in FSAR Section 4b.3 and Subsection 7.5.4.1.6. The MEPS heating loops extend outside of the supercell; radioactive material in the loop would lead to increased radiological doses to workers, as described in FSAR Subsection 13b.1.2.3 (Scenario 14). Two channels of radiation monitors are provided for each extraction hot cell. Radiation exceeding 1000 1100 mR/hr results in a MEPS Heating Loop Isolation for that heating loop for the associated extraction cell, and provides margin to an analytical limit of 2500 mR/r.
