SUMMARY

PUBLIC VERSION FINAL SAFETY ANALYSIS REPORT MARKUP

Chapter 7 - Instrumentation and Control Systems Process Integrated Control System Control Functions None Interlocks and Permissives None 7.3.1.3.11 Target Solution Vessel Reactivity Protection System and Engineered Safety Features Actuation System The TRPS and ESFAS are the safety-related control systems for the main production facility, as described in Sections 7.4 and 7.5, respectively.

Safety-related radiation monitors are also within the scope of the TRPS and ESFAS, as described in Subsection 7.7.1. These components are used to monitor radiation in the radiological ventilation (RV) system and are discussed in Subsection 7.3.1.4.5 Monitoring and Alarms The PICS receives input from the TRPS and ESAFS and provides alarms related to the status and functionality of the safety-related control systems (e.g., communication errors, faulted modules, failed power supplies).

Control Functions The PICS provides signals to the TRPS and ESFAS to provide normal control ofSafety-related components that are capable of being actuated by the TRPS or ESFAS. C, but also have a nonsafety-related function related to production, achieve their safe state by having power removed. PICS controls these components directly by cycling power through the use of relays and contacts and does not send a signal to the TRPS or ESFAS during these normal operations.

Should a safety actuation be required, the TRPS or ESFAS opens a contact in series with the power supply to the component, causing it to achieve its safe state regardless of the control signals from the PICS are only accepted by. Following the safety actuation, the PICS provides a nonsafety-related control signal to the TRPS andor ESFAS whento allow for component repositioning. The actuation and priority logic (APL) in the TRPS or ESFAS processes these signals based upon the position of the associated enable nonsafety switch located on the main control board is in the enable position. Details of the control signals provided by PICS are described in Subsections 7.4.3.4 and 7.5.3.3.

Safety-related components that are capable of being actuated by the TRPS or ESFAS and do not have a nonsafety-related production function are not controlled directly by PICS. Following the safety actuation, the PICS sends a nonsafety-related control signal to the TRPS or ESFAS and the APL in the TRPS or ESFAS processes this signal based upon the position of the enable nonsafety switch. If not prevented by higher priority inputs to the APL, the TRPS or ESFAS will position the component as requested by the PICS.

Engineered Safety Features Chapter 7 - Instrumentation and Control Systems Actuation System Each division of the ESFAS contains three redundant 125 VDC to 24 VDC converters. The 24 VDC power is distributed to each of three chassis mounting bays, where it is then used to power two redundant 24 VDC to 5 VDC converters located beneath each chassis bay. These provide independent +5-volt (V) A and +5V B power channels to each chassis. This configuration allows for the architecture to handle a single failure of a power supply.

7.5.3.4 Operating Conditions The ESFAS control and logic functions operate inside of the facility control room where the environment is mild and not exposed to the irradiation process, and is not subject to operational cycling. However, the cables for the ESFAS are routed through the radiologically controlled area to the process areas. The routed cables have the potential to be exposed to more harsh conditions than the mild environment of the facility control room. The sensors are located inside the process confinement boundary; therefore, the terminations of the cables routed to the sensors are exposed to the high radiation environment.

During normal operation, the ESFAS equipment will operate in the applicable normal radiation environments identified in Table 7.2-1 for up to 20 years, replaced at a frequency sufficient such that the radiation qualification of the affected components is not exceeded. The radiation qualification of the affected components is based upon the total integrated dose (TID) identified in Table 7.2-1 being less than the threshold values identified in industry studies.

The environmental conditions for ESFAS components are outlined in Table 7.2-1 through Table 7.2-3. The facility heating, ventilation and air conditioning (HVAC) systems are relied upon to maintain the temperature and humidity parameters in these areas. The facility HVAC systems are described in Section 9a2.1.

7.5.3.5 Seismic, Tornado, Flood The ESFAS equipment is installed in the seismically qualified portion of the main production facility where it is protected from earthquakes, tornadoes, and floods. The ESFAS equipment is Seismic Category I, tested using biaxial excitation testing and triaxial excitation testing, in accordance with Section 8 of IEEE Standard 344-2013 (IEEE, 2013) (Subsection 7.5.3.12).

7.5.3.6 Human Factors The ESFAS provides manual actuation capabilities for the safety functions identified in Subsection 7.5.3.1, except for the IU Cell Nitrogen Purge signal which originates in the TRPS, via the following manual push buttons located on the main control board:

  • Supercell Isolation (performs Supercell Areas 1 through 10 Isolations and MEPS A/B/C Heating Loop Isolations)
  • VTS Actuation
  • TPS Isolation (performs TPS Train A/B/C Isolation and TPS Process Vent IsolationActuation)
  • Carbon Delay Bed Group 1 Isolation
  • Carbon Delay Bed Group 2 Isolation
  • Carbon Delay Bed Group 3 Isolation
  • Extraction Column A Alignment Actuation SHINE Medical Technologies 7.5-34 Rev. 6

Engineered Safety Features Chapter 7 - Instrumentation and Control Systems Actuation System 7.5.4.1.7 High PVVS Carbon Delay Bed Exhaust Carbon Monoxide The high PVVS carbon delay bed group 1/2/3 exhaust carbon monoxide signals protect against a fire in the PVVS delay bed (Subsection 13b.1.2.5, Scenario 1). The signal is generated by ESFAS for the associated carbon delay bed group (Group 1, 2, or 3) when a carbon delay bed group 1/2/3 exhaust carbon monoxide input exceeds the high level setpoint. The PVVS carbon delay bed group 1/2/3 exhaust carbon monoxide is measured with an analog interface on two different channels, one for each Division A and Division B of ESFAS. When one-out-of-two or more PVVS carbon delay bed group 1/2/3 exhaust carbon monoxide channels exceed their setpoint, then a Carbon Delay Bed Isolation for the affected group is initiated.

7.5.4.1.8 VTS Vacuum Header Liquid Detection The VTS vacuum header liquid detection signal protects against an overflow of the vacuum lift tanks to prevent a potential criticality event as described in Subsection 6b.3.2.5. The VTS vacuum header liquid detection signal is received by the ESFAS as a discrete input from a liquid detection switch on two different channels, one for each Division A and Division B of ESFAS.

When one-out-of-two or more (Division A and Division B) VTS vacuum header liquid detection channels indicate liquid is detected, then a VTS Safety Actuation is initiated.

7.5.4.1.9 RDS Liquid Detection The RDS liquid detection signal detects leakage or overflow from other tanks and piping (Subsection 13b.1.2.3, Scenarios 8, 10, 11, 12, and 16). The RDS liquid detection signal is received by the ESFAS as a discrete input from a liquid detection switch on two different channels, one for each Division A and Division B of ESFAS. When one-out-of-two or more RDS liquid detection channels indicate liquid is detected, then a VTS Safety Actuation is initiated.

7.5.4.1.10 High TPS IU Cell 1/2/3/4/5/6/7/8 Target Chamber Exhaust Pressure The high TPS IU Cell 1/2/3/4/5/6/7/8 target chamber exhaust pressure signal protects against a break in the tritium exhaust lines in the IU cell (Subsection 13a2.1.6.2, Scenario 3 and Subsection 13a2.1.12.2, TPS Scenario 3). The signal is generated by ESFAS when a target chamber exhaust pressure input exceeds the high level setpoint. The TPS IU Cell 1/2/3/4/5/6/7/8 target chamber exhaust pressure is measured with an analog interface on two different channels, one for each Division A and Division B of ESFAS. When one-out-of-two or more TPS IU Cell 1/2/3/4/5/6/7/8 target chamber exhaust pressure inputs exceed the allowable limit, the appropriate TPS Train A/B/C Isolation isand an RCA Isolation are initiated.

7.5.4.1.11 High TPS IU Cell 1/2/3/4/5/6/7/8 Target Chamber Supply Pressure The high TPS IU Cell 1/2/3/4/5/6/7/8 target chamber supply pressure signal protects against a break in the tritium supply lines in the IU cell (Subsection 13a2.1.6.2, Scenario 3 and Subsection 13a2.1.12.2, TPS Scenario 3). The signal is generated by ESFAS when a target chamber supply pressure input exceeds the high level setpoint. The TPS IU Cell 1/2/3/4/5/6/7/8 target chamber supply pressure is measured with an analog interface on two different channels, one for each Division A and Division B of ESFAS. When one-out-of-two or more TPS IU Cell 1/2/3/4/5/6/7/8 target chamber supply pressure inputs exceed the allowable limit, the appropriate TPS Train A/B/C Isolation isand an RCA Isolation are initiated.

Engineered Safety Features Chapter 7 - Instrumentation and Control Systems Actuation System 7.5.4.1.12 High TPS Exhaust to Facility Stack Tritium The high TPS exhaust to facility stack tritium signal protects against a release of tritium from the TPS glovebox pressure control exhaust and VAC/ITS process vent exhaust into the facility ventilation systems (Subsection 13a2.1.12.2, TPS Scenario 3 and TPS Scenario 4). The signal is generated by ESFAS when a TPS exhaust to facility stack tritium input exceeds the high level setpoint. The TPS exhaust to facility stack tritium is measured with an analog interface on three different channels, one for each division of ESFAS. When two-out-of-three or more TPS exhaust to facility stack tritium channels exceed their setpoint, then a TPS Process Vent Actuation is initiated.

7.5.4.1.13 High TPS Confinement Tritium The high TPS confinement A/B/C tritium signals protect against a release of tritium from TPS equipment into the associated TPS glovebox (Subsection 13a2.1.12.2, TPS Scenario 1). A signal is generated by ESFAS when a TPS confinement A/B/C tritium input exceeds its high level setpoint. There is an independent and separate tritium measurement for each of the three TPS trains. TPS confinement tritium concentration is measured using an analog interface on two different channels per glovebox, one for each Division A and Division B of ESFAS. When one-out-of-two or more TPS confinement A/B/C tritium channels exceed their setpoint (for a particular glovebox), then a TPS Train A Isolation, TPS Train B Isolation, or TPS Train C Isolation is initiated for the respective TPS train along with an RCA Isolation.

7.5.4.1.14 TRPS IU Cell 1/2/3/4/5/6/7/8 Nitrogen Purge The TRPS IU cell 1/2/3/4/5/6/7/8 nitrogen purge signal protects against a loss of hydrogen mitigation capabilities in the irradiation units (Subsection 13a2.1.2.2, Scenario 5 and Subsection 13a2.1.9.2, Scenario 1). The signal is generated by an affected TRPS subsystem and provided to the ESFAS when the TRPS initiates an IU Cell Nitrogen Purge, as described in Subsection 7.4.3.1.2. The TRPS IU cell 1/2/3/4/5/6/7/8 nitrogen purge signal is transmitted as a discrete input from the TRPS on two different channels, one for each Division A and Division B of ESFAS. When a TRPS IU cell 1/2/3/4/5/6/7/8 nitrogen purge indicates purging, then an ESFAS IU Cell Nitrogen Purge is initiated.

7.5.4.1.15 Low PVVS Flow The PVVS flow signal protects against loss of hydrogen mitigation capabilities in the RPF (Subsection 13a2.1.6.2, Scenario 7). The signal is generated by ESFAS when a PVVS flow input exceeds the low level setpoint. The PVVS flow is measured with an analog interface on three different channels, one for each division of ESFAS. When two-out-of-three or more PVVS flow channels exceed their setpoint, then an RPF Nitrogen Purge is initiated.

7.5.4.1.16 MEPS Area A/B/C Three-Way Valve Position Indication The MEPS area A/B/C three-way valve position indication signals protect against a misalignment of the extraction column upper and lower three-way valves, degrading one of the barriers preventing misdirection of chemical reagents or target solution (Subsection 13b.1.2.3, Scenario 15).

Chapter 7 - Instrumentation and Control Systems Control Console and Display Instruments Transmission of information between systemsPICS and TRPS or ESFAS is through unidirectional data transfers. Each of the safety system communications to the nonsafety PICS system is through one-way data communications from the safety systems to the nonsafety system. There are no inputs to the TRPS or ESFAS from the PICS that are used in the determination of protective actions, as described in Subsections 7.4.2.1.6 and 7.5.2.1.6. There are no unidirectional communications that allowfrom the nonsafety system to communicate back to the safety systems preventing the ability tothat would propagate a failure from the nonsafety control system displays to the safety control systems. The PICS communication to the FDCS is through a one-way data diode such that no communication from outside of the PICS (other than the inputs from the safety-related control systems) can have an impact on the operation of the PICS. CIn normal use, communications of the indication and diagnostic information of the TRPS and ESFAS to the maintenance workstation are through a unidirectional point-to-point communication bMonitoring and Indication Bus so that the maintenance workstation does not have an effect oninfluence the TRPS or ESFAS. The maintenance workstation is provided with a separate switch-controlled Calibration and Test Bus for performance of inputs to TRPS and ESFAS for updating parameters and testing activities.

A failure in the display systems results in distinct display changes, which directly indicate that depicted plant conditions are invalid.

The PICS is designed in a manner that allows operators to remove static display screens and equipment control displays from service without impacting the operation of the remaining portions of the PICS displays.

The PICS has in-service self-testing capabilities such that the system will alarm if individual points or an entire rack or cabinet loses communications or faults.

7.6.4.6 Technical Specifications and Surveillance Certain material in this section provides information that is used in the technical specifications.

This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be referenced in, the bases that are described in the technical specifications.

6.5 CONCLUSION

The SHINE facility control room is located in the non-radiologically controlled area of the main production facility and contains the necessary workstations, displays, and control cabinets needed for the operation of the main production facility. The main control board, PICS operator and supervisor workstations, and associated control cabinets are considered part of the PICS.

As part of the PICS, the main control board, operator workstations, and supervisor workstation are not credited with performing safety functions and only assist operators in performance of normal operations or diverse actuations to the safety systems.

5. Tritium migrates to the IF through the IU cell plugs and is released to the environment.
6. Detection of high radiation in the RCATPS target chamber supply pressure or high TPS target chamber exhaust pressure actuates ventilation dampers between the RCA and the environment and minimizes the transport of radioactive material to the environment.
7. Personal dosimeters, local radiation alarms, and alarms in the facility control room notify facility personnel of radiation leakage.
8. Facility personnel evacuate the immediate area within 10 minutes upon actuation of the radiation alarms.

Radiation transport is driven primarily by barometric breathing between the IU cell and the IF.

The safety-related SSCs in the IU cell do not fail during a seismic event, but the NDAS and its internal components are not safety-related and cannot be relied upon to remain intact following a design basis earthquake.

No operator actions are taken or required to reach a stabilized condition or to mitigate dose consequences.

Safety Controls The safety controls credited for mitigation of the dose consequences for this accident are:

  • Primary confinement boundary
  • TPS Train Isolation on high TPS target chamber supply pressure or high TPS target chamber exhaust pressure
  • Ventilation isolation mechanisms
  • Holdup volume in the RVZ1e
  • Facility personnel evacuate the immediate area within 10 minutes after receipt of electronic dosimeter or local radiation alarms It is assumed that the primary confinement is intact and performs a mitigation function with respect to radionuclide transport from the IU cells to the IF. The primary confinement boundary components are designed to maintain their integrity under postulated accident conditions and are maintained in accordance with the facility configuration management and maintenance systems.

13a2.2.6.4 Damage to Equipment Failure of the NDAS vacuum boundary does not cause subsequent damage to equipment. While the NDAS vacuum boundary integrity is not seismically qualified to maintain integrity, the NDAS is designed to maintain structural integrity during and following a design basis earthquake.

After the initial IU cell pressurization has reached equilibrium, leakage between the IU cells and the IF is driven primarily by barometric breathing. The leakage between the cells and the IF is not impacted by the accident sequence.

Chapter 13 - Accident Analysis Accident Analysis and Determination of Consequences 13a2.2.12.1.1 Initial Conditions Initial conditions for facility-specific events are described in Subsection 13a2.1.12.1.

13a2.2.12.1.2 Initiating Event An internal NDAS vacuum boundary component fails and causes a pressurized release of tritium and SF6 gas into the IU cell. Potential causes of the initiating event are discussed in Subsection 13a2.1.12.2.

13a2.2.12.1.3 Sequence of Events It is assumed that the primary confinement is intact and performs a mitigation function with respect to radionuclide transport from the IU cell to the IF. The primary confinement is designed to maintain its integrity under postulated accident conditions and is maintained in accordance with the facility configuration management and maintenance programs.

1. The initiating event is a vacuum boundary component failure in the NDAS, which instantaneously releases tritium and SF6 gas into the IU cell.
2. The IU cell becomes slightly pressurized due to the mass of released SF6 gas.
3. Tritium is transported into the IF through penetrations in the confinement boundary.
4. Detection of high TPS target chamber supply pressure or high TPS target chamber exhaust pressure actuates the primary confinement boundary isolation valves and an irradiation unit trip within 20 seconds of detection. A sufficient time delay is provided by the holdup volume in RVZ1e to prevent radioactive gases from exiting through RVZ1e prior to isolation.
5. Tritium migrates to the IF through penetrations in the primary confinement boundary and is released to the environment.
6. Detection of high radiation in the RCATPS target chamber supply pressure or high TPS target chamber exhaust pressure actuates ventilation dampers between the RCA and the environment and minimizes the transport of radioactive material to the environment.
7. Personal dosimeters, local radiation alarms, and alarms in the facility control room notify facility personnel of radiation leakage.
8. Facility personnel evacuate the immediate area within 10 minutes upon actuation of the radiation area monitor alarms.

Radiation transport is primarily driven by barometric breathing between the IU cell and the IF.

Safety Controls The safety controls credited for mitigation of the dose consequences for this accident are:

  • Primary confinement boundary (IU cell plugs and seals)
  • TPS Train Isolation on high TPS target chamber supply pressure or high TPS target chamber exhaust pressure
  • IU cell ventilation isolations
  • Holdup volume in the RVZ1e
  • Facility personnel evacuate the immediate area within 10 minutes after receipt of electronic dosimeter or local radiation alarms SHINE Medical Technologies 13a2.2-25 Rev. 6

Chapter 13 - Accident Analysis Accident Analysis and Determination of Consequences confinement boundary is described in detail in Section 6a2.2. Potential causes of the initiating event are discussed in Subsection 13a2.1.12.3.

13a2.2.12.2.3 Sequence of Events It is assumed that the tritium confinement boundary is intact and performs a mitigation function with respect to radionuclide transport from the TPS to the IF. The tritium confinement boundary components are designed to maintain their integrity under postulated accident conditions and are maintained in accordance with the facility configuration management and maintenance programs.

1. The initiating event is a seismic event that causes a break in two TPS trains and instantaneously releases the tritium inventory into their respective TPS gloveboxes.
2. For the first 20 seconds, tritium escapes from each of the gloveboxes to the IF through the glovebox pressure control exhaust process vent to RVZ1.
3. The glovebox ventilation shuts down after 20 seconds due to high TPS confinement A/B/C tritium monitors.
4. During the 30 seconds after the initiating event, the TPS room vents to the IF at an elevated rate due to the facility RVZ2 ventilation system.
5. The RVZ2 ventilation damper from the TPS room isolates after 30 seconds due to high TPS confinement A/B/C tritium monitors.
6. The radioactive material is then dispersed throughout the IF and exits the facility to the environment through building penetrations.
7. Detection of high TPS confinement A/B/C tritium actuates ventilation dampers between the RCA and the environment and minimizes the transport of radioactive material to the environment.
8. Personal dosimeters, local radiation alarms, and alarms in the facility control room notify facility personnel of radiation leakage.
9. Facility personnel evacuate the immediate area within 10 minutes upon actuation of the radiation area monitor alarms.

Throughout the accident sequence, the leakage rate between each TPS glovebox and the TPS room is constant. After the TPS room ventilation is isolated, radiation transport is driven by air exchange between each TPS glovebox and the IF. Transport to the environment occurs through RCA boundary leak paths. The accident duration used in this analysis is 10 days, after which it is assumed that recovery actions will have occurred to stop further release and dispersion of radioactive material.

Safety Controls The safety controls credited for mitigation of this accident are:

  • TPS room ventilation isolations
  • Glovebox pressure control and VAC/ITS ventilation isolations
  • TPS confinement A/B/C tritium monitors
  • Tritium confinement boundary, as described in Section 6a2.2
  • Facility personnel evacuate the immediate area within 10 minutes after receipt of electronic dosimeter or local radiation alarms
  • Tritium release event recovery actions are completed within 10 days SHINE Medical Technologies 13a2.2-27 Rev. 6
