ATTACHMENT 1 10 CFR 50.54(q)(5) Procedure Change Summary Analysis Page 1 of 2

. 1 O CFR 50.54(g)(5) Procedure Change Summary Analysis ProcedurefTitle Exelon Generation Company, LLC (EGC) is submitting the following Emergency Plan Addendum revision for Three Mile Island Nuclear Station (TMI):

EP-AA-1009, Addendum 1, Revision 2, "Three Mile Island Station On-Shift Staffing Technical Basis" Description of Procedure EP-AA-1009, Addendum 1 provides the technical basis for the Emergency Response Organization (ERO) minimum on-shift staffing at TMI.

Description of Changes The changes to EP-AA-1009, Addendum 1, clarify the task assignments for four (4) on-shift Radiation Protection (RP) and Chemistry ERO minimum staff positions.

The activities for the RP Technicians and Chemistry technicians are identified in Table 4 for each scenario in Attachment 1 of the Addendum. For the RP technician actions, the actions were distributed across the three (3) RP technicians. Review by Site RP staff determined that, although there are currently three (3) RP technicians assigned to the ERO minimum on-shift staff complement, the assigned tasks only require the resources of two (2) RP technicians.

Given the procedural direction and priorities for each scenario, there are no more than two (2) required actions in any of the scenarios requiring RP technician support. Based upon this assessment by the site RP staff, the Table 4 Notes for each of the affected attachments were revised to more accurately reflect the required personnel resources for each scenario. The revision reassigned tasks, but did not change or delete any of the identified tasks.

For the Chemistry technician, the site Chemistry staff confirmed that the tasks assigned to the Chemistry technician in Attachments 3C, 3F, and 3G of the Addendum are not time critical and would not typically be performed within the first 60 minutes for these scenarios (i.e., Table 4).

Based upon this assessment by the site Chemistry.staff, the Table 4 Notes for each of the affected attachments were revised to more accurately reflect the non-time-critical nature of these tasks.

Description of How the Changes Still Comply with Regulations Planning Standard 1 O CFR 50.47(b)(2) requires that on-shift facility licensee responsibilities for emergency response are unambiguously defined and that adequate staffing to provide initial facility accident response in key functional areas is maintained at all times. Program Element from NUREG-0654, Section 11.B requires licensees to specify the emergency response organization and funCtions. 1 O CFR 50, Appendix E,Section IV.A, requires licensees to have a detailed analysis demonstrating that on-shift personnel assigned emergency plan implementation functions are not assigned responsibilities that would prevent the timely performance of their assigned functions as specified in the emergency plan. The changes Page 2 of 2 1 O CFR 50.54(q)(5) Procedure Change Summary Analysis support the applicable Planning Standard requirements and Program Element guidance by ensuring that the technical basis for the required on-shift minimum staffing remains consistent with the guidance provided in NSIR/OPR-ISG-01and the methodology specified in NEI 10-05.

These changes clarify that the resources of two (2) RP technicians are sufficient to perform the applicable tasks specified under EP-AA-1009, Addendum 1, Attachments 3C, 30, 3F, 3G, 31, and 3J. Assessment by TMI RP staff concluded that the required RP tasks for each Table 4 scenario can be performed by two (2) RP technicians with no un*acceptable collateral duties.

The RP staff assessment is demonstrated in the revised Attachments 3C, 30, 3F, 3G, 31, and 3J. Specifically, the assessment shows that the identified tasks can be performed by two (2) RP technicians without impacting their respective emergency response functions or the station's response to the emergency.

These changes also clarify that there are no required Chemistry technician tasks within the first 60 minutes following an event. The specific actions involve sampling of the Reactor Building (RB) sumps following a Loss of Coolant Accident (LOCA) or Control Rod Ejection, or Turbine Building sumps for a Steam Generator Tube Rupture (SGTR). Review of these actions with the station Chemistry and Operations staff determined that these actions would be directed by Operations and would not be expected to be performed during the initial 60 minutes following the initiating event.

Existing requirements and capabilities under TMl's Emergency Plan have not been deleted or reduced as part of this revision and as such, the station Emergency Plan continues to meet regulatory requirements. A review of existing regulatory commitments was made to ensure all

• existing commitments continue to be met.

Description of Why the Changes are Not a Reduction in Effectiveness (RIE)

Existing requirements and capabilities under TMl's Emergency Plan have not been deleted or reduced as part of this revision and as such, the station's Emergency Plan continues to meet regulatory requirements. A review of existing regulatory commitments was made to ensure all existing commitments continue to be met. The changes do not impact the capability or timeliness of the on-shift staff to perform any time sensitive emergency response tasks and do not constitute a reduction in effectiveness of the Emergency Plan at TMI.

1.0 INTRODUCTION

An On-Shift Staffing Analysis (OSA) was conducted at Three Mile Island (TMI). This OSA satisfies the requirement of Section IV.A.9 of 1 O CFR 50, Appendix E, which states that nuclear power reactor licensees shall perform "a detailed analysis demonstrating that on-shift personnel assigned emergency plan implementation functions are not assigned responsibilities that would prevent the timely performance of their assigned functions as specified in the emergency plan." A structured approach was utilized to perform this analysis using the guidance found in NEI 10-05, Rev 0, "Assessment of On-Shift Emergency Response Organization Staffing and Ca,pabilities" and EP-AA-130, "10 CFR 50, On-Shift Staffing Assessment". This analysis examined the ability of the minimum staff listed in Table TMI 2-1 of the Three Mile Island Station Emergency Plan Annex (EP-AA-1009, Rev 19) to perform all of the actions necessary to respond to each of the event scenarios specified in NEI 10-05, as well as implement all of the required actions required by the Emergency Plan. The analysis considered both Unit 1 and the permanently shutdown Unit 2.

• This analysis was conducted by a joint team of corporate Emergency Preparedness (EP) persohnel and station personnel from the Operations, Radiation Protection and Emergency Preparedness (EP) departments. Additionally, personnel from Engineering, Security, and Chemistry provided input to the analysis.

SUMMARY

The OSA team determined that an on-shift staff of twenty (20) is required to support all of the Emergency Plan functions for the scenarios evaluated in the staffing

• assessment. The on-shift staff consists of individuals necessary to support each of the following Emergency Plan Functional Areas:

Plant Operations & Safe Shutdown

• . Fire Fighting Radiation Protection & Chemistry Emergency Plan Implementation July 2016 Page 2 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear NEI 10-05 states it is acceptable for certain functions to be assigned to personnel already assigned other functions/tasks. These include Repair and Corrective Action, Rescue Operations and First Aid.

The On-Shift Staffing Assessment identified gaps between the technical bases identified through this assessment and the current staffing practices. These gaps were identified and corrected using the station's Corrective Action Program (TMI IR 1425128)., Three Mile Island On-Shift Staff provides the on-shift assessment results presented in the NU REG 0654, Table B-1 format. Attachment 3, NEI 10-05 Appendix B Staffing Tables for Three Mile Island Station contains the final NEI 10-05 Assessment tables providing the results of each scenario assessment.

2.1.

Emergency Plan Minimum Staffing Per 1 O CFR 50.54 (q)(1)(iii), Emergency planning function means a capability or resource necessary to prepare for and respond to a radiological emergency, as set forth in the elements of section IV of appendix E to this part and, for nuclear power reactor licensees, the planning standards of§ 50.47(b).

The following table indicates the result of the NEI 10-05 staffing analysis of on-shift personnel to perform the required emergency planning functions and the licensing basis requirement for each on-shift position.

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear a~o ANALYSIS PROCESS This analysis was conducted by a joint team of corporate Emergency Preparedness (EP) personnel and station personnel from the Operations, Radiation Protection and Emergency Preparedness (EP) departments. Additionally, personnel from Chemistry, Engineering and Security provided input to the analysis.

The emergency response to each event was determined by conducting a tabletop of the event using the emergency plan and procedures and the applicable department procedures such as Operations emergency and abnormal operating procedures.

Each scenario was reviewed by the cross disciplinary team to determine what plant actions and emergency plan implementation actions were required based on plant procedures prior to staff augmentation. These actions were then compared to the minimum staffing for Emergency Plan implementation as described in the Emergency Plan Annex, EP-AA-1009, Table 2-1, ensuring that no actions were assigned to staff members that conflicted with either their dedicated emergency plan role or their dedicated operational role as appropriate. In cases where multiple tasks were assigned to an individual in their role, the team assessed timing of the tasks to ensure that they could be performed by the individual in series within any specified time requirements.

The results of the analysis for each of the scenarios are included in Attachment 3, NEI 10-05 Appendix 8 Staffing Tables for Three Mile Island Station.

Note that NSIR DPR-ISG-01, "Interim Staff Guidance - Emergency Planning for Nuclear Power Plants" states that only OBA accidents "which would result in an emergency declaration" should be evaluated in the staffing assessment. Each of TMl's DBA's were evaluated and classified according to its UFSAR Chapter 14 description. If the accident description alone did not result in a classification, the projected accident dose rate at the site boundary was utilized to determine if an EAL threshold would be exceeded within the first 90 minutes using the Abnormal Rad Level EAL thresholds. hi cases where several projected dose rates were provided or July 2016 Page 5 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear release data was not detailed significantly to determine an EAL, the assessment used the radiological consequences associated with the realistic case in accordance with NEI 10-05.

4.0 SCENARIO SELECTION AND ATTRIBUTES The OSA scenarios were chosen using the guidance of NEI 10-05 and NSIR/DPR-ISG-01. The evaluation considered the station Design Basis Accidents along with 4 additional scenarios specified by the guidance documents. The scenarios consisted of:

Design Basis Threat (DBT) ground assault Aircraft Probable Threat Fire requiring evacuation of the Control Room and plant shutdown from remote location, (Appendix R *Fire)

Large Break Loss of Coolant Accident, (LOCA)

Station Blackout, (SBO)

Main Steam Line (MSL) Break Accident Steam Generator Tube Rupture Control Rod ejection accident Fuel Handling Accident Waste Gas Tank Rupture Fire in ESAS Room Feedwater Line Break Accident Reactor Coolant Pump Shaft Seizure The results of the analysis for each of the scenarios are included in Attachment 2, NEI 10-05 Scenario Tables. The selection of OBA accidents for inclusion in this assessment was based in part on the guidance contained in NSIR DPR-ISG-01 which states that only OBA accidents "which would result in an emergency declaration" should be evaluated in the staffing assessment. Each of TMl's DBAs were evaluated and classified according to its UFSAR description. Additionally, the projected accident dose rate at the site boundary was considered in classification. In cases where several projected dose rates were provided, the assessment used the July 2016 Page 6 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear radiological consequences associated with the realistic case in accordance_ with NEI 10-05.

Each scenario was assessed by the cross disciplinary team to determine what plant actions and emergency plan implementation actions were required based on plant procedures prior to staff augmentation. These actions were then compared to the minimum staffing for Emergency Plan implementation as described in the Emergency Plan Annex, EP-AA-1009, Table 2-1, ensuring that no actions were assigned to staff members that conflicted with either their dedicated emergency plan role or their dedicated operational role as appropriate. In cases where multiple tasks were assigned to an individual in their role, the team considered task prioritization and duration to ensure that they could be performed by the individual in series within any specified time requirements.

4.1.

Severe Accident Mitigation Guidelines (SAMG)

NEI 10-05 guidance required one scenario to evaluate implementation of the Severe Accident Mitigation Guidelines. The Large Break Loss of Coolant Accident was chosen for this purpose at TMI. The analysis of the ability to implement severe accident management guidelines focused on the reasonably expected initial mitigation actions that would be performed by on-shift personnel other than licensed and non-licensed operators consistent with NEI 10-05 guidance.

4.2.

Station Blackout TMI elected to evaluate a Station Blackout as part of this analysis as recommended in NEI 10-05. It was assumed that designated station equipment (e.g., blackout diesel generators, SBO dedicated source) were available as credited in the Station Blackout Analysis. This assumption is consistent with the NEI 10-05 position that unplanned/unexpected actions that address equipment failures are contingent in nature and cannot be specified in advance.

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear 5.0 ACCIDENT SCENARIOS Except as noted, all scenarios assume the plant is operating with minimum staff at full power and no abnormal conditions exist.

Design Basis Threat - A HOSTILE FORCE breaches the Protected Area fence, but is neutralized with no adverse consequences to plant safety.

Aircraft Probable Threat - Notification is received from the NRC that a probable aircraft threat exists (> 5 minutes, < 30 minutes).

Fire Requiring Control Room Evacuation - A fire occurs in the Control Room requiring the room to be evacuated and Remote Shutdown procedures to be implemented.

Design Basis Loss of Coolant Accident - A OBA LOCA occurs with all automatic actions occurring as designed and expected. Concurrent with the LOCA, the unit experiences a radiological release. The classification for this scenario is stipulated to be a General Emergency per NEI 10-05 guidance. After the notifications are complete, it is assumed that the SAMGs are required to be implemented. A review of the SAMGs associated with the initial site-specific Candidate High Level Actions concluded that no actions would require on-shift personnel other than Licensed and Non-Licensed Operators.

Station Blackout - A loss of all offsite AC power occurs coincident with the trip of the unit. Both Unit 1 emergency diesel generators fail to start. Operator successfully starts SBO diesel generator.

Steam Generator Tube Rupture - Double-ended Steam Generator Tube Rupture occurs (leak exceeds charging pump capacities). Unit TRIP occurs on Low Reactor Coolant System Pressure.

Control Rod Ejection Accident - The most reactive control rod assembly is suddenly and violently ejected from reactor vessel from the rod insertion limit position. Reactor Protection System actuates a reactor trip and an automatic July 2016 Page 8 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear Safety Injection. Containment and RCS indications are consistent with a loss of coolant accident.

Waste Gas Tank Rupture - Rupture of a waste gas tank resulting in the release of its radioactive contents to the Auxiliary Building environment.

Fire in the ESAS Room - A fire in the ESAS Room occurs requiring the shift to implement contingency procedures to ensure plant control is maintained while simultaneously fighting the fire. This is the most manpower limiting Appendix R fire.

5.1.

DBAs not evaluated under the Staffing Assessment Main Steam Line Break - The postulated accident is a sudden, complete severance of one main steam line outside containment with subsequent release of steam and water containing fission products to the intermediate building and the turbine building. This OBA would not result in classification from plant conditions or resultant dose.

Feedwater Line Break - The postulated accident is a sudden, circumferential break downstream of the outermost isolation valve. This OBA would not result in classification from plant conditions or resultant dose.

Reactor Coolant Pump Shaft Seizure - The postulated accident is indication of reactor coolant pump shaft seizure resulting in loss of the Reactor Coolant Pump.

This OBA would not result in classification from plant conditions or resultant dose.

Fuel Handling Dropped Fuel Assembly - The postulated event involves the drop of a fuel assembly on top of the reactor core, resulting in clad damage. NRG EPFAQ 2013-008 concluded this accident did not need to be evaluated under this analysis.

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear 6.0 GENERAL ASSUMPTIONS AND LIMITATIONS 6.1.

RP and Chemistry:

TMI utilized the analysis approach described by NEI 10-05 to identify all tasks assigned to on-shift radiation protection and chemistry technicians. Required tasks were plotted on a timeline considering task duration and priority. There were no overlapping times identified for TMI. It should be noted that there were no time critical activities identified in station procedures for the scenarios reviewed. Tasks would be identified and prioritized by the Emergency Director. Station procedure EP-AA-112-1 OO-F-01, Shift Emergency Director Checklist, contains a generic step requiring one RP technician to be assigned to support shift activities. This includes any acce~s control or RP coverage tasks as identified in station procedures and documented in each staffing assessment scenario evaluation.

The RP and Chemistry tasks reviewed were those directed by the Shift Manager to support actions in Abnormal Operating Procedures (AOP), Emergency Operating Procedures (EOP), and Emergency Implementing Procedures (EIP). Any additional tasks directed by the Technical Support Center (TSC), Operations Support Center (OSC), or Emergency Operations Facility (EOF) procedures were not reviewed.

6.2.

Repair and Corrective Action:

Per the guidance of NUREG-0654, Table B-1, repair and corrective action tasks may be performed by dedicated shift personnel or qualified shift personnel assigned other functions/tasks. Repair and corrective action is defined as:

An action that can be performed promptly to restore a non-functional component to functional status (e.g., resetting a breaker), or to place a component in a desired configuration (e.g., open a valve), and which does not require work planning or implementation of tag out controls to complete.

In accordance with NEI 10-05 section 2.5, the staffing analysis included a review of the maintenance and corrective action tasks. These tasks are allowed to be performed by personnel having other EP functions. For the purpose of this analysis, the tasks were considered to fall into two broad categories:

July 2016 Page 10 of 98 EP-AA-1009 Addendum 1 (Revision 2)

\\

}

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear Unplanned/unexpected actions that address equipment failures. These actions are contingent in nature and cannot be specified in advance.

Planned/expected actions performed in support of operating procedure implementation, including severe accident management guidelines.

At TMI, the repair and corrective action tasks are performed by plant equipment operators and maintenance personnel. Equipment operators at TMI are qualified to install jumpers, lift & land leads, and other tasks as directed by the plant operating procedures. There were no tasks identified that would require performance by non-operations personnel.

6.3.

Rescue Operations and First Aid:

In accordance with NEI 10-05 section 2.6, the analysis also included a review of the Rescue Operations and First Aid Responses. These functions are also allowed to be performed by personnel assigned other EP functions. Rescue Operations and First Aid include the tasks of locating missing personnel, removing them from hazardous areas, if needed, and providing necessary initial medical treatment. Personnel performing initial medical treatment are trained to the level of Red Cros_s Basic First Aid. At TMI, these functions are performed by the Fire Brigade Incident Commander and a Radiation Protection Technician.

6.4.

1 OCFR50.54(hh) Aircraft Threat The analysis included a review of the implementation of the requirement to maintain continuous communications with the notification source during an aircraft threat in accordance with 1 OCFR50.54(hh) and Reg Guide 1.214. There are no specific qualifications required to perform this task and the function is not required to be assigned in advance. This review identified that there are sufficient personnel on-shift to perform this action during the aircraft event. Specifically, a Reactor Operator, the Radiation Protection technicians and the Chemistry personnel were all available to fill this function.

July 2016 Page 11 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear 6.5.

Site Specific Event Notifications The requirements for additional corporate specific notifications were reviewed and identified. Exelon procedure OP-M-106-101, "Significant Event Reporting" permits delegation of the Event Notifications to the Duty Station Manager or Corporate Nuclear Duty Officer (NDO). The initial notification to the Duty Station Manager constitutes a simple and brief communication in accordance with NEI 10-05 se.ction 3.1.13 and does not require further assessment.

6.6.

ERO Response Time - Evaluation of 90 Minutes As stated in NEI 10-05, section 2.14, the staffing assessment methodology may be used to evaluate proposed changes to on-shift staffing levels or augmented ERO response times. The TMI staffing assessment evaluation utilized an ERO response time of 60 minutes. However, the assessment team reviewed the identified emergency response functions and actions through the first 90 minutes following the declaration.

It was determined the on-shift operations staff would have no additional actions or require additional staff in implementing actions to mitigate and stabilize the accident within the additional 30 minutes. Note that the analysis methodology did not require any assumptions of additional equipment failures to complicate the event.

Additionally, RP and Chemistry staff would be able to continue to support and prioritize activities during the additional 30 minutes until the augmented staff arrives.

This is indicated on Table 4 of the scenario assessments for RP and Chemistry. The Fire Brigade would continue to be available to support plant activities as required by the scenario.

6. 7.

Emergency Plan Legacy Staffing Functions Repair and Corrective Action - Functional Area 5 was revised to both clarify the existing requirements for Repair and Corrective Action (R&CA) personnel and to identify and maintain the legacy application of these requirements. TMI Emergency Plan Annex Table 2-1 stipulates the following for R&CA:

July 2016 Page 12 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Maintenance/RadWaste(n) (OSC)

Electrical Maintenance I l&C (n) (OSC)

OSC Director 1(f)I3 1(f)I3 1

Exelon Nuclear Note (n) states in part, a total of six personnel, in addition to two (2) Auxiliary Operators listed under Control Room Staff, are available to support shift repair I corrective actions: Two (2) additional Auxiliary Operators; three (3) Maintenance personnel; and One (1) Senior Maintenance Technician....

Note (f) states that these positions can be filled by personnel assigned other functions.

The OSC Director position is filled by a Maintenance Supervisor, who also is the Fire Brigade Leader. For clarity, TMI has revised the annotation of the R&CA functions on Table 2-1.

Maintenance/RadWaste(n) (OSC)

Electrical Maintenance I l&C (n) (OSC)

OSC Director Note (a) states the position can be filled by personnel assigned other functions.

NU REG 0654 and NEI 10-05 discuss the R&CA functions as a collateral duty that can be performed by persons assigned other positions. However, in order to maintain the existing total number of on-shift staff at TMI, two of the positions are annotated without having the ability to perform concurrent functions. This was done to maintain the current staffing numbers at TMI such that there would not be a reduction in staff resulting from this assessment. This was not done as a result of any identified need to have dedicated Maintenance Techs as part of the assessment results.

The TMI Staffing Assessment results still maintain the legacy requirements for six (6)

Repair and Corrective Action persons plus an OSC Director, just as before.

However, four (4) of R&CA and the OSC director are now annotated as being filled by personnel assigned other functions. These positions were shared by members of the Fire Brigade. Historically, the Fire Brigade function did not contain the assigned July 2016 Page 13 of 98 EP-AA-1009 Addendum 1 (Revision 2)

' \\

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear number of personnel since these members were already accounted for under R&CA function. Following the guidance of NEI 10-05, it was decided to account for the specific number of Fire Brigade members under the Fire Brigade function instead of accounting for them under the R&CA function, and to annotate under the R&CA function that these positions can be assigned to personnel filling other functions.

This revision is appropriate because it continues to allow the same personnel to fill both the Fire Brigade and R&CA positions, as is the present practice, while preventing the Fire Brigade from being assigned concurrent duties such as Safe Shutdown, STA or EP Communicator. This revision had no impact on the total on-shift staffing numbers or the historical dedication of ERO personnel, but rather allowed the flexibility for the R&CA function to be a shared function, which is consistent with both NU REG 0654 and NEI 10-05.

Note that TMI exceeds the industry norm for personnel supporting the Repair and Corrective Action function. The revision to the Table 2-1 R&CA Function was intended to 1) provide additional clarity on appropriate utilization of on-shift personnel since the Fire Brigade numbers were added to Table 2-1, 2) maintain current station staffing levels, ar:id 3) establish the basis that these R&CA persons had no actions or tasks in the Staffing Assessment.

Security Supervisor - The function of Security Supervisor was removed from Table 2-.

1. The Security Supervisor is staffed per the requirements of the TMI Security Plan.

Deleting this position does not reduce the requirement to staff this position and the annotation is consistent with NU REG 0654. Note that the function of Accountability is still maintained on Table 2-1.

Shift Communicator - Section 2.1.2 of the TMI Emergency Plan annex describes the position of the Emergency Communicator. At TMI, Reactor Operators and Maintenance (l&C) personnel are both qualified as Shift Communicators. TMl's practice has been to have the flexibility to utilize either of these staff to perform the Shift Communicator function. The TMI table 2-1 is being revised to state this position is filled by Plant Personnel who is not assigned any other EP function. The annotation of which department performs this function is removed.

July 2016 Page 14 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear Additionally, the Emergency Annex section 2.1 was revised to remove reference to specific departments filling the shift communicator function. The Staffing Assessment determined that one communicator is sufficient to fill this function as long as the communicator has no other concurrent EP responsibilities. The table reflects one person assigned to this position but does not alter or change the option to utilize other qualified personnel to perform the task if requested.

6.8.

NEI 10-05 General Assumptions

1.

Response time used for this analysis was the maximum acceptable number of minutes elapsed between emergency declaration and the augmented ERO position holder at a location necessary to relieve an on-shift position of the emergency response task. As discussed in NEI 10-05, the evaluation was extended to 90 minutes to support future licensing actions.

2.

On-shift personnel complement was limited to the minimum required number and composition as described in the site emergency plan. If the plan commitments allow for different minimum staffing levels (e.g., a variance between a n,ormal dayshift and a backshift), the staffing with the smallest total number of personnel was used for the analysis.

3.

Although the temporary absence of a position may be allowed by Tech Specs, the analysis was performed assuming that all required on-shift positions are filled.

4.

The event occurred during off-normal work hours where the ERO was offsite and all required minimum on-shift positions were filled.

5.

On-shift personnel reported to their assigned response locations within timeframes sufficient to allow for performance of assigned actions.

6.

On-shift staff had necessary Radiation Worker qualification to obtain normal dosimetry and enter the radiological control area (RCA) (but not locked high or very high radiation areas) without the aid of a RP technician.

July 2016 Page 15 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear

7.

Personnel assigned plant operations and SSD met the requirements and guidance (analyzed through other programs such as operator training) and were not evaluated as part of this assessment unless a role/function/task from another major response area was assigned as a collateral duty.

8.

In-plant (manual) safety related operator actions to manipulate components and equipment from locations outside the control room to achieve and maintain safe shutdown was performed by a member of the on-shift staff.

9.

Fire brigade (FB) staff performance is analyzed through other station programs (e.g., fire drills) and was not evaluated as part of this assessment unless a role/function/task from another major response area was assigned as a collateral duty.

1 O.

Individuals holding the position of RP technician or Chemistry technician are qualified to perform the range of tasks expected of their position.

11.

Security was not evaluated unless a role or function from another major response area was assigned as a collateral duty.

12.

Communications, briefings, and peer checks are acceptable collateral duties.

13.

The Staffing Analysis specified the resources available to perform "Repair and Corrective Actions" and "Rescue Operations and First Aid" but these may be assigned as collateral duties to a designated on-shift responder.

14.

For assessment purposes, NRC notifications were treated as a continuous action per 10CFR50.72(c)(3) and 73.71(b)(1). This means once the initial NRC communications are established, the NRC will request an open line be maintained with the NRC Operations Center.

15. Unless otherwise specified in NSIR/DPR-ISG-01, Interim Staff Guidance -

Emergency Planning for Nuclear Power Plants, or by the initial conditions of a OBA analysis, it was assumed that the unit was in Mode 1.

16.

DBT assumed a hostile force breached the protected area fence but was neutralized with no adverse consequences to plant safety. Damage inflicted on plant systems, structures and components was not sufficient to prevent safe shutdown or cause a radiological release. There was no fire significant enough to warrant firefighting efforts prior to arrival of offsite resources and/or the augmented ERO.

17.

The Staffing Analysis used OBA analysis assumptions, inputs, timing of events as documented in the UFSAR.

18.

In cases where a OBA analysis included a radiological release, and the starting point of the release was not clearly defined, the staffing analysis assumed that the release began at the time of declaration of the initiating event.

19.

Severe Accident Management Guideline (SAMG) - It is sufficient to simply assume that the accident progressed to conditions requiring a severe accident response; it did not include determining specific failures and the accident sequence.

20.

SAMG - The actions analyzed included those that implement the initial site-specific actions assuming the core is not ex-vessel (i.e., no reactor vessel failure), and there is no actual or imminent challenge to containment integrity.

7.0 CONCLUSION

The report documents the completion of the TMI On-Shift Staffing Assessment per NEI 10-05. The analysis concluded the following:

The results of the On-Shift Staffing Assessment concluded that 20 persons are required. The staffing required by EP-AA-1009, Table TMI 2-1 of the Emergency Plan Annex reflects the required staff to perform all of the EP and operational actions required to respond to each NEI 10-05 scenario in addition to legacy staff commitments currently identified in the Emergency Plan.

It is important to note that this assessment specifically addressed the ability of the Site minimum staffing to support required EP and Operations functions for the July 2016 Page 17 of 98 EP-AA-1009 Addendum 1 (Revision 2)

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear scenarios analyzed. Table 2-1 does not address functions or tasks that are outside of the procedures utilized in the evaluated scenarios. For example, additional personnel may be required on-shift to support some offsite functions unrelated to this assessment (e.g., routine switchyard, waste treatment plant, intake structure_

operations). Additional staffing may be required through station administrative procedures to accomplish these tasks. reflects the results of the staffing assessment as well as including the legacy staff commitments from the c~rrent Emergency Plan.

TMI Station On-Shift Staffing Technical Basis Exelon Nuclear 0 Large Break Loss of Coolant Accident (LOCA)

1.

Accident Summary:

A OBA LOCA occurs with all automatic actions occurring as designed and expected. Concurrent with the LOCA, the unit experiences a radiological release. The classification for this scenario is stipulated to*

be a General Emergency per NEI 10-05 guidance. After the notifications are complete, it is assumed that the Severe Accident Mitigation Guidelines are required to be implemented.

A review of the SAMGs associated with the initial site-specific Candidate High Level Actions concluded that no actions would require on-shift personnel other than Licensed and Non-Licensed Operators.

2.

Accident Specific Assumptions:

There was no other plant damage and all equipment operates as designed.
