24 2 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Executive Summary This report documents the results of an assessment of the capability of the Duane Arnold Energy Center (DAEC) minimum on-shift staff and augmented Emergency Response Organization (ERO) to respond to a beyond design basis external event (BDBEE). The assumptions for the scenario are based on accepted industry guidance and postulate that the BDBEE involves a large-scale external natural event that results in: A. An extended loss of AC power (HAP) B. An extended loss of the ultimate heat sink (LUHS) C. Unit in operation at the time of the event D. Impeded access to the unit by off-site responders as follows: *
- Oto 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> post event -No site access. (Initial Phase)
- 6 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> post event -Limited site access. Individuals may access the site by walking, personal vehicle or via alternate tran-sportation capabilities (e.g., private resource providers or public sector support). (Transition Phase)
- 24+ hours post event -Improved site access. Site access is restored to a normal status and/or augmented transportation resources are available to deliver equipment, supplies, and large numbers of personnel. (Final Phase) The assessment of the minimum on-shift staffing was performed by a team of DAEC subject matter experts from Operations, Radiation Protection, Security, Emergency Preparedness, and the FLEX project team. The team performed the staffing assessment on March 23-24 2016. The participants reviewed the assumptions and applied existing procedural guidance, including applicable draft Severe Accident Management Procedures (SAMPs) for coping with a BDBEE using minimu*m on-shift staffing.
Particular attention was given to the sequence and timing of each procedural step, its duration, and the on-shift individual performing the step to account for both the task and the time duration analyses of NEI 10-05, Assessment of On-Shift Emergency Response Organization and Capabilities.
The on-shift staffing analysis concluded that there were no task overlaps for the activities that were assigned to the on-shift personnel.
However, SAMP task training was not complete at the time of this assessment.
Training will be delivered to E-plan on-shift staff and applicable qualifications applied and maintained to implement the FLEX strategies.
These training 3 FUKUSHTh1A RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER activities are tracked by AR 1744135-24.
No additional shift staffing is necessary to implement the mitigating strategies for DAEC. The evaluation utilized the minimum E-plan .on-shift staff from Operations, Radiation Protection, Chemistry, Fire and Security to accomplish all applicable event response tasks. 4 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Introduction This report documents a preliminary staffing assessment for a Beyond Design Basis External Event for Duane Arnold Energy Center. The assessmen*t was performed using guidance in NEI 12-01, "Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communication Capabilities," and NEI 12-06, "Diverse and Flexible Coping Strategies (FLEX) Implementation Guide," to determine the response of on-shift and augmented resources to an Extended Loss of Power (ELAP). The assessment addresses Phase 1 and 2 of the analysis applicable to implementation of existing and preliminary FLEX strategies for prolonged loss of offsite power initial and transition phases of the event, utilizing the methodology of NEI 10-05, "Assessment of On-Shift Emergency Response Organization Staffing and Capabilities." The procedures, at the time of the assessment, were in a draft development state. When the procedures are finalized, a review will be conducted to ensure inputs to this staffing analysis remain valid. The assessment was conducted using draft Severe Accident Management Procedures (SAMPs) and Emergency Operating Procedure (EOP) revisions.
Use of these procedures is acceptable in accordance with NEI 12-01: "In accordance with the Order, each licensee must develop new strategies for mitigating the effects of beyond-design-basis external events. To ensure accurate results, the staffing assessment for response functions related to NTTF Recommendation 4.2 must be based on actions delineated in the procedures and guidelines developed in response to the Order. Once the site-specific actions associated with the new response strategies are defined (e.g., down to the procedure or guideline step level), the staffing needed to perform these actions can be assessed with the necessary level of accuracy." The assessment considers required actions performed during the Initial and Transition Phases of an ELAP (first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). Evaluation of the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of response is acceptable in accordance with NEI 12-01, Section 3.1 and NEI 12-06, Section 12.1: "Following successful implementation of Transition Phase coping strategies, there is a , third phase characterized by the ability to cope indefinitely; this is referred to as the Final Phase (Phase 3). The Final Phase would involve the use of equipment and consumables transported to the site from offsite locations, including ongoing replacement and replenishment as needed. The demands placed upon the ERO during this phase are not significantly different than those associated with Transition Phase coping." 5 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER "On-site resources will be used to cope with the first two phases of the casualty for a minimum of the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the event." Staffing Assessment Process Overview Draft strategies for responding to an ELAP and draft Severe Accident Management Procedures (SAMPs) were evaluated during the NEI 12-01 Phase 2 Staffing Assessment by a disciplined team .. The staffing assessment also addressed the ability of the on-shift staff to perform any required emergency response functions prior to the delayed arrival of the augmented Emergency Response Organization (ERO).
- The Phase 2 staffing assessment requires that the ELAP scenario be evaluated based on the minimum staffing in the Emergency Plan (NEI 12-01) and the supplemental staff allowed by the minimum administrative staffing procedures (NEI 12-06). DAEC Radiological Emergency Plan Table B-1, Revision 37 documents the approved minimum Emergency Plan on-shift staff. Table 1 below summarizes the available personnel.

FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER The DAEC FIRE PROTECTION PROGRAM FP-AB-100 identifies Fire Brigade staffing as being composed of the Assistant Nuclear Station Operating Engineer (RO) as the Fire Brigade Leader, Maintenance (2), Security, (1) and the Radwaste operator (1). NEI 12-01 Phase 2 Assessment Results No conflicts or overlaps in functions or tasks required to be performed by on-shift operations and support personnel were identified during this analysis.
Transition Phase actions were within the first six hours of the event. Using NEI 12-01 and NEI 12-06 guidance, the minimum on-shift staff (as defined in the DAEC Emergency Plan B Response Organization" Rev 37, Table B-1) performed all actions required by operating and emergency plan procedures in the first phase relying only on installed structures, systems and components in the initial phase of the response.
After the ELAP condition was declared, functional draft Severe Accident Management Procedures and applicable attachments were successfully implemented.
They were performed using on-shift resources during the first six (6) hours and augmented responders from six (6) to twenty-four
{24) hours as necessary for relief. DAEC's phase 2 FLEX response relies upon the use of portable equipment.
An evaluation of the SAMPs was conducted for the scenario.
Validation
& Verification (V & V} of the FLEX portable equipment deployment was conducted prior to the table top evaluation.
The V & V was completed to determine the resources needed and estimated durations of each task associated with the strategy.
The staffing assessment used the total number of resources identified and task durations to ensure DAEC can respond to an ELAP. The primary response to an ELAP event at DAEC is with installed equipment in phase one and portable equipment in phase 2. A review of draft SAMPs was conducted to determine the resources needed and estimated durations of each task associated with the strategy.
The total number of resources identified and task duration were then used to identify the two most resource limiting FLEX strategies.
This analysis identified that the two most resource limiting FLEX strategies are:
- SAMP 724, FLEX Damage Assessment and Portable Equipment Deployment
- SAMP 722, FLEX Repowering Battery Chargers from FLEX 480 VAC DG There were no required staffing or Emergency Plan changes identified during this assessment.
7 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Phase 2 Staffing Assessment Details The Phase 2 staffing assessment for DAEC was conducted on March 24 and 25, 2016 with a Simulator Validation Scenario on March 25, 2016, using the guidance of NEI 12-01, NEI 12-06 and NEI 10-05. The following personnel were present to complete the assessment:

NEI 12-01-Assumptions for Staffing Assessment:
- 1. A large-scale external event occurs that results in:
- extended loss of AC power
- impeded access to the unit 2. Initially, the reactor is operating at full power and is successfully shut down. 3. A Hostile Action directed at the affected site does not occur during the period that the site is responding to the event. 4. The event impedes site access as follows: a. Post-event time: 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> -No site access. This duration reflects the time necessary to clear roadway obstructions, use different travel routes, mobilize alternate transportation capabilities (e.g., private resource providers or public sector support), etc. b. Post-event time: 6 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> -Limited site access. Individuals may access the site by walking, personal vehicle or via alternate transportation capabilities (e.g., private resource providers or public sector support).
- c. Rost-event time: 24+ hours -Improved site access. Site access is restored to a near-normal status and/or augmented transportation resources are . available to deliver equipment, supplies and large numbers of personnel.
- 5. On-shift personnel are limited to the minimum complement allowed by the site emergency plan and Fire Protection Program. 9 FUKUSHIMA RESPONSE NEI 12-01PHASE2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER NEI 10-05 -Applicable Assumptions:
- 1. On-shift personnel can report to their assigned response locations within
- timeframes sufficient to allow for performance of assigned actions, 2. The on-shift staff possesses the necessary Radiation Worker qualifications to obtain normal dosimetry to enter Radiological Controlled Areas (but not locked high or very high radiation areas) without the aid of a Radiation Protection Technician . . 3. Personnel assigned to the major response area of Plant Operations
& Safe Shutdown meet the requirements and guidance established by NRC regulations and are able to satisfactorily perform the functions and tasks necessary to achieve and maintain safe shutdown.
Staff performance within this area is not evaluated as part of this assessment, unless a role/function/task from another major response_
area is assigned as a collateral duty. 4. On-site security organization:
Performance of this function is regularly analyzed through other station programs and will not be evaluated here, unless a role or function from another major response area is assigned as a collateral duty. 5. Individuals holding the position of radiation Protection technician or chemistry technician are qualified to perform the range of tasks expected of their position.
- 6. The task of making a simple and brief communication has minimal impact on the ability to perform other assigned functions/tasks, and is therefore an acceptable collateral duty for all positions.
This assumption does not apply to emergency notification to an Offsite Response Organization (ORO) or the NRC. These actions must be assessed.
- 7. The task of performing a peer check has minimal impact on the ability to perform other assigned functions/tasks, and is therefore an acceptable collateral duty for all positions.
- 8. The analyzed events occur during off-normal work hours at a time when most augmented ERO responders are not at the site (e.g., during a backshift, weekend or holiday).
For purposes of this analysis, and consistent with NEI 12-01 assumption
- 4, 360 minutes (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) will be used as the time period for the conduct of on-shift ERO response actions. 10 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER NEI 12-06 Assumptions

METHODOLOGY An assessment of on-shift staffing was performed using NEI 12-01, NEI 12-06 and NEI 10-05 guidance.
Subject matter_ experts were assembled to provide analysis support. The assessment was conducted via a tabletop procedural analysis using DAEC procedures to determine iftasks have been sufficiently analyzed for performance by the minimum on-shift staff as designated in the Emergency Plan as allowed by NEI 12-06. The following provides a summary of the process that was used. Each on-shift position from Emergency Plan Section 'B' Emergency Response Organization TABLE B-1 and any additional administrative on-shift position were entered in NEI 10-05 Appendix 1, Table 1. For position titles with more than one position holder, a unique sequential number was assigned to each position.
The site emergency plan reference that
- describes the requirement for the position to be on-shift was then entered into column 3 of Appendix 1, NEI 10-05 Table 1. Firefighting was not applicable for this assessment.
Using only the on-shift positions entered in the table, the following Appendix 1 tables were completed by entering the shift position that fills a described role, or performs a specific function or tasks:

For _each position, the table number and associated line number was then entered in column 4, "Role in Table#/Line#".
If the associated task required additional actions, a "Yes" was placed in the last column and the additional action recorded in the results section ofthis report. The On-Shift Staffing Assessment (OSA) was conducted using the following process: 1. Selection of_ the multi-disciplined work group 2. Scheduling the tabletop at the DAEC Operations support Center (OSC) to allow ready access to required procedures and administrative documents
- 3. Conduct of a pre-jolJ briefing outlining the requirements of NEI 12-01, NEI 12-06 and NEI 10-05 4. Review of the event initial conditions and assumptions*
- 5. Performance of the procedural analysis 6. Documentation of the results of the tabletop by Fukushima project group using the NEI 10-05 forms modified to extend to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This review provided the team with a basic understanding of the event and resulting emergency classifications.
The SRO reviewed EOP, AOP and SAMP actions and identified them to the team. The procedures for FLEX strategies are in draft status which is adequate for a staffing assessment.
When the procedures are finalized a review of the staffing assessment will be performed to ensure that the staffing assessment results have not changed. This activity is tracked by AR 2126130. Resources needed to perform the initial and transition phase response actions were identified from the EOP, AOP, or SAMP procedures and documented.
The team determined when other on-shift resources, such as the RP or Chemistry Technician, would be required and identified 14 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER the time required to perform expected emergency plan functions.
This information was documented on the applicable tables in this report. Finally, the on-shift resources and their actions were summarized in the tables using the NEI 10-05 documentation process in Appendix 1, NEI 10-05 Table 1. One scenario, ELAP with loss of Ultimate Heat Sink was reviewed.
15 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Security Considerations Existing emergency procedures do not require the use of Security Officers to perform duties unrelated to their assigned roles. However, planned mitigation strategies require Members of the Security Force (MSF) to perform duties unrelated to their assigned roles, (e.g., debris removal and equipment staging).
Security Officers will perform functions within their current roles such as monitoring, damage assessment and controlling sites access and providing compensating measures for any vital area doors that may need to remain open to facilitate room environmental conditions and hose and personnel passage. To the extent practical; security posture and security functions will be relaxed to facilitate immediate onsite and offsite response to the emergency.
No additional events or failures are assumed to occur prior to or during a BDBEE including security events. In preparation for response to an ELAP and a LUHS an alternative security_approach has been developed.
This alternative approach will enable event mitigation, while ensuring a level of protection appropriate for the circumstance.
This approach is a site specific plan which includes elements such as establishing unassisted access for event mitigation and providing security personnel to assist with event mitigation.
The site security department will be trained and prepared to implement the alternative approach when properly authorized.
This training activity is tracked by AR 1744135-24.
Security personnel shall be the last group requested for assistance and the first group relieved once additional emergency response personnel arrive onsite. Security positions selected for reassignment to FLEX response activities are tiered and sequenced and consider position reassignment impacts to security responses under the protective strategy from the "least impactful".
This is in line with the NRC guidance for an ELAP event for reassigning Security officers to FLEX response activities.
Site specific staffing assessments have estimated that 28 MSFs will be trained as FLEX Auxiliary Responders and will be responsible for debris removal from travel paths, transporting onsite portable equipment to staged locations, and assisting in deployment of hoses and cables. Of the possible 5 shift responders, 2 will be assigned per shift as FLEX Auxiliary Responders, -available as needed for postulated beyond design basis events. 16 FUKUSHIMA RESPONSE NEI 12-01PHASE2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER DAEC responses to Staffing Assessment Questions Related to Use of Security Personnel during a BOB Event Response 1.
- How has the site evaluated the use of on-shift personnel (excluding security) to address staffing and the movement of equipment for a beyond design basis event in phases 1, 2, and 3 mitigating strategies?
DAEC Response:
The site has evaluated the use of on-shift personnel (excluding security) to address staffing and the movement of equipment for a beyond design basis event in phases 1, 2, and 3 mitigating strategies in accordance with the NRC staff-endorsed guidance contained in NEI 12-01, Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communications Capabilities.
NOTE -The Mitigating Order and NRC JLD-ISG-2012-01 refers to' Phases 1, 2 and 3 as the Initial Phase, Transition Pbase and Final Phase, respectively.
- 2. All apparent immediate actions taken to address the condition without the use of security (e.g., the exhaustive use of other site personnel).
a.) How is "immediately" defined for the use of security personnel to support the site event? DAEC Response:
Immediately is defined as the moment at which the senior license operator in the Control Room determines that an event has occurred, or plant conditions are present, which will require implementation of Severe Accident Management procedures (e.g., deployment of Initial Phase and/or Transition Phase Mitigating strategies).
17 FUKUSHIMA RESPONSE NEI 12-01PHASE2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER b.) What are the other actions that may be taken before using 10 CFR 73.SS(p)?
DAEC Response:
Through implementation of the appropriate procedures and guidelines, Control Room operators will select the appropriate mitigating strategies for responding to the post-event plant conditions, and direct the performance of the in-field/plant actions necessary to implement these strategies.
Consistent with the goal of protecting public health and safety, implementation of strategies will utilize the site staff in such a way as to ensure that equipment retrieval and operation occurs within the timeframes necessary to maintain safety functions.
- 3. Is the site considering the use of security personnel for other beyond design basis events that are not characterized by the conditions outlined within the guidance document?
If so what are these events and the associated rationale for using security personnel?
DAEC Response:
No; the site is not considering the use of Security personnel for other beyor:id design basis events that are not characterized by the conditions outlined within the , guidance document.
- 4. Technical information concerning why the use of Security P.ersonnel would address the condition.
DAEC response:
The use of security personnel would address the condition because of their availability as a response resource to the Control Room and will help to ensure that mitigating strategies are implemented within the timeframes necessary to maintain safety functions.
Such implementation will preclude or minimize offsite radiological consequences, and thus contribute to the protection of public health and safety. [NOTE: No additional events or failures are assumed to occur immediately prior to or during the event including security events] Security personnel will be supporting implementation of the following event mitigation procedures and guidelines:
- SAMP 724-FLEX Damage Assessment and Portable Equipment Deployment 18 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER 5. If security is used to meet staffing requirements and the placement of equipment, what phase(s) would require their support? DAEC Response:
Security support would be necessary during Phase 1 and Phase 2 (Initial Phase and Transition Phase). 6. The rationale concerning the use of security personnel:
a.) How many secu.rity personnel are necessary to support the event? DAEC Response:
Two (2) security personnel are necessary to support the event. b.) What security requirements in part or total are impacted by the use of the security personnel?
DAEC Response:
An Assessment Table below represents the response to 6b. Non-Safeguards Staffing Assessment Table Position Mitigating Strategy Duty Operate pre-staged heavy equipment and Auxiliary Responder
- 1 perform debris removal. 'May also include assisting plant Operations with deployment of FLEX equipment as necessary.
Operate pre-staged heavy equipment and Auxiliary Responder
- 2 perform debris removal. May also include assisting plant Operations with deployment of FLEX equipment as necessary.
c.) What is the estimated duration for the use of security personnel?
DAEC Response:
Notwithstanding the uncertainties associated with a beyond design basis event, the estimated duration is bounded as stated below. 19 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER
- As noted earlier, the "start time" is the moment at which the senior licensed operator in the Control Room determines that an event has or plant conditions are present, which will require implementation of Severe Accident Management Procedures (e.g., deployment of Initial Phase and/or Transition Phase mitigating strategies).
- With respect to the "end time", it is anticipated that augmented ERO staff would be able to access the site at around 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> following the event. Allowing for some margin in the arrival times of ERO
- personnel, the need to do job briefings and turnovers, the release of security personnel from mitigating strategies duties should occur . during the period of approximately 6 to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the initiating event. d.) What are the duties that will be assigned to security personnel?
DAEC Response:
See response to question 6b, above. The staffing assessment has verified that the designated security personnel do not have non-security related task assignments that would prevent them from performing their mitigating strategy implementation duties (i.e., no assigned collateral duties). Response training for security personnel will be developed in accordance with the guidance in NEI 12-06. e.) What actions will be required to restore security to its normal posture? DAEC Response:
The actions that will allow for dismissal of security personnel from duties associated with implementation of mitigating strategies would be the arrival of a sufficient number of augmented ERO personnel.
Once dismissed, security personnel may resume their normal duties. Appropriate procedures and guidelines will contain instructions to the effect that absent an overriding safety consideration, security personnel will receive priority consideration for mitigating strategy duty relief by the augmented ERO. 7. Is the use of security personnel conducted via a tiered approach to minimize impact to security response capability?
Use of security personnel should be sequenced such 20 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER that security personnel whose reassignment will adversely
- impact security the least are reassigned first (e.g. use security personnel who are performing admini.strative functions before those who are implementing the protective strategy).
DAEC Response:
Yes; the use of security personnel was determined via a tiered approach to minimize the impact to security response capability.
The selection of personnel considered assigned functions and potential impacts to the protective strategy.
The assignments were .made such that security personnel with the least impact to the protective str;;itegy were reassigned first. The assignment shown in the Table above (response to question 6b) reflects the selection rationale; least to greater impact Strategy Resource Loading Selected SAMPs were reviewed to determine the resources needed and estimated durations of each task associated with the FLEX strategy.
The resources and time frames have been incorporated into Table 2B for ELAP response.

24 2 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Executive Summary This report documents the results of an assessment of the capability of the Duane Arnold Energy Center (DAEC) minimum on-shift staff and augmented Emergency Response Organization (ERO) to respond to a beyond design basis external event (BDBEE). The assumptions for the scenario are based on accepted industry guidance and postulate that the BDBEE involves a large-scale external natural event that results in: A. An extended loss of AC power (HAP) B. An extended loss of the ultimate heat sink (LUHS) C. Unit in operation at the time of the event D. Impeded access to the unit by off-site responders as follows: *
- Oto 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> post event -No site access. (Initial Phase)
- 6 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> post event -Limited site access. Individuals may access the site by walking, personal vehicle or via alternate tran-sportation capabilities (e.g., private resource providers or public sector support). (Transition Phase)
- 24+ hours post event -Improved site access. Site access is restored to a normal status and/or augmented transportation resources are available to deliver equipment, supplies, and large numbers of personnel. (Final Phase) The assessment of the minimum on-shift staffing was performed by a team of DAEC subject matter experts from Operations, Radiation Protection, Security, Emergency Preparedness, and the FLEX project team. The team performed the staffing assessment on March 23-24 2016. The participants reviewed the assumptions and applied existing procedural guidance, including applicable draft Severe Accident Management Procedures (SAMPs) for coping with a BDBEE using minimu*m on-shift staffing.
Particular attention was given to the sequence and timing of each procedural step, its duration, and the on-shift individual performing the step to account for both the task and the time duration analyses of NEI 10-05, Assessment of On-Shift Emergency Response Organization and Capabilities.
The on-shift staffing analysis concluded that there were no task overlaps for the activities that were assigned to the on-shift personnel.
However, SAMP task training was not complete at the time of this assessment.
Training will be delivered to E-plan on-shift staff and applicable qualifications applied and maintained to implement the FLEX strategies.
These training 3 FUKUSHTh1A RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER activities are tracked by AR 1744135-24.
No additional shift staffing is necessary to implement the mitigating strategies for DAEC. The evaluation utilized the minimum E-plan .on-shift staff from Operations, Radiation Protection, Chemistry, Fire and Security to accomplish all applicable event response tasks. 4 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Introduction This report documents a preliminary staffing assessment for a Beyond Design Basis External Event for Duane Arnold Energy Center. The assessmen*t was performed using guidance in NEI 12-01, "Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communication Capabilities," and NEI 12-06, "Diverse and Flexible Coping Strategies (FLEX) Implementation Guide," to determine the response of on-shift and augmented resources to an Extended Loss of Power (ELAP). The assessment addresses Phase 1 and 2 of the analysis applicable to implementation of existing and preliminary FLEX strategies for prolonged loss of offsite power initial and transition phases of the event, utilizing the methodology of NEI 10-05, "Assessment of On-Shift Emergency Response Organization Staffing and Capabilities." The procedures, at the time of the assessment, were in a draft development state. When the procedures are finalized, a review will be conducted to ensure inputs to this staffing analysis remain valid. The assessment was conducted using draft Severe Accident Management Procedures (SAMPs) and Emergency Operating Procedure (EOP) revisions.
Use of these procedures is acceptable in accordance with NEI 12-01: "In accordance with the Order, each licensee must develop new strategies for mitigating the effects of beyond-design-basis external events. To ensure accurate results, the staffing assessment for response functions related to NTTF Recommendation 4.2 must be based on actions delineated in the procedures and guidelines developed in response to the Order. Once the site-specific actions associated with the new response strategies are defined (e.g., down to the procedure or guideline step level), the staffing needed to perform these actions can be assessed with the necessary level of accuracy." The assessment considers required actions performed during the Initial and Transition Phases of an ELAP (first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). Evaluation of the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of response is acceptable in accordance with NEI 12-01, Section 3.1 and NEI 12-06, Section 12.1: "Following successful implementation of Transition Phase coping strategies, there is a , third phase characterized by the ability to cope indefinitely; this is referred to as the Final Phase (Phase 3). The Final Phase would involve the use of equipment and consumables transported to the site from offsite locations, including ongoing replacement and replenishment as needed. The demands placed upon the ERO during this phase are not significantly different than those associated with Transition Phase coping." 5 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER "On-site resources will be used to cope with the first two phases of the casualty for a minimum of the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the event." Staffing Assessment Process Overview Draft strategies for responding to an ELAP and draft Severe Accident Management Procedures (SAMPs) were evaluated during the NEI 12-01 Phase 2 Staffing Assessment by a disciplined team .. The staffing assessment also addressed the ability of the on-shift staff to perform any required emergency response functions prior to the delayed arrival of the augmented Emergency Response Organization (ERO).
- The Phase 2 staffing assessment requires that the ELAP scenario be evaluated based on the minimum staffing in the Emergency Plan (NEI 12-01) and the supplemental staff allowed by the minimum administrative staffing procedures (NEI 12-06). DAEC Radiological Emergency Plan Table B-1, Revision 37 documents the approved minimum Emergency Plan on-shift staff. Table 1 below summarizes the available personnel.

FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER The DAEC FIRE PROTECTION PROGRAM FP-AB-100 identifies Fire Brigade staffing as being composed of the Assistant Nuclear Station Operating Engineer (RO) as the Fire Brigade Leader, Maintenance (2), Security, (1) and the Radwaste operator (1). NEI 12-01 Phase 2 Assessment Results No conflicts or overlaps in functions or tasks required to be performed by on-shift operations and support personnel were identified during this analysis.
Transition Phase actions were within the first six hours of the event. Using NEI 12-01 and NEI 12-06 guidance, the minimum on-shift staff (as defined in the DAEC Emergency Plan B Response Organization" Rev 37, Table B-1) performed all actions required by operating and emergency plan procedures in the first phase relying only on installed structures, systems and components in the initial phase of the response.
After the ELAP condition was declared, functional draft Severe Accident Management Procedures and applicable attachments were successfully implemented.
They were performed using on-shift resources during the first six (6) hours and augmented responders from six (6) to twenty-four
{24) hours as necessary for relief. DAEC's phase 2 FLEX response relies upon the use of portable equipment.
An evaluation of the SAMPs was conducted for the scenario.
Validation
& Verification (V & V} of the FLEX portable equipment deployment was conducted prior to the table top evaluation.
The V & V was completed to determine the resources needed and estimated durations of each task associated with the strategy.
The staffing assessment used the total number of resources identified and task durations to ensure DAEC can respond to an ELAP. The primary response to an ELAP event at DAEC is with installed equipment in phase one and portable equipment in phase 2. A review of draft SAMPs was conducted to determine the resources needed and estimated durations of each task associated with the strategy.
The total number of resources identified and task duration were then used to identify the two most resource limiting FLEX strategies.
This analysis identified that the two most resource limiting FLEX strategies are:
- SAMP 724, FLEX Damage Assessment and Portable Equipment Deployment
- SAMP 722, FLEX Repowering Battery Chargers from FLEX 480 VAC DG There were no required staffing or Emergency Plan changes identified during this assessment.
7 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Phase 2 Staffing Assessment Details The Phase 2 staffing assessment for DAEC was conducted on March 24 and 25, 2016 with a Simulator Validation Scenario on March 25, 2016, using the guidance of NEI 12-01, NEI 12-06 and NEI 10-05. The following personnel were present to complete the assessment:

NEI 12-01-Assumptions for Staffing Assessment:
- 1. A large-scale external event occurs that results in:
- extended loss of AC power
- impeded access to the unit 2. Initially, the reactor is operating at full power and is successfully shut down. 3. A Hostile Action directed at the affected site does not occur during the period that the site is responding to the event. 4. The event impedes site access as follows: a. Post-event time: 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> -No site access. This duration reflects the time necessary to clear roadway obstructions, use different travel routes, mobilize alternate transportation capabilities (e.g., private resource providers or public sector support), etc. b. Post-event time: 6 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> -Limited site access. Individuals may access the site by walking, personal vehicle or via alternate transportation capabilities (e.g., private resource providers or public sector support).
- c. Rost-event time: 24+ hours -Improved site access. Site access is restored to a near-normal status and/or augmented transportation resources are . available to deliver equipment, supplies and large numbers of personnel.
- 5. On-shift personnel are limited to the minimum complement allowed by the site emergency plan and Fire Protection Program. 9 FUKUSHIMA RESPONSE NEI 12-01PHASE2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER NEI 10-05 -Applicable Assumptions:
- 1. On-shift personnel can report to their assigned response locations within
- timeframes sufficient to allow for performance of assigned actions, 2. The on-shift staff possesses the necessary Radiation Worker qualifications to obtain normal dosimetry to enter Radiological Controlled Areas (but not locked high or very high radiation areas) without the aid of a Radiation Protection Technician . . 3. Personnel assigned to the major response area of Plant Operations
& Safe Shutdown meet the requirements and guidance established by NRC regulations and are able to satisfactorily perform the functions and tasks necessary to achieve and maintain safe shutdown.
Staff performance within this area is not evaluated as part of this assessment, unless a role/function/task from another major response_
area is assigned as a collateral duty. 4. On-site security organization:
Performance of this function is regularly analyzed through other station programs and will not be evaluated here, unless a role or function from another major response area is assigned as a collateral duty. 5. Individuals holding the position of radiation Protection technician or chemistry technician are qualified to perform the range of tasks expected of their position.
- 6. The task of making a simple and brief communication has minimal impact on the ability to perform other assigned functions/tasks, and is therefore an acceptable collateral duty for all positions.
This assumption does not apply to emergency notification to an Offsite Response Organization (ORO) or the NRC. These actions must be assessed.
- 7. The task of performing a peer check has minimal impact on the ability to perform other assigned functions/tasks, and is therefore an acceptable collateral duty for all positions.
- 8. The analyzed events occur during off-normal work hours at a time when most augmented ERO responders are not at the site (e.g., during a backshift, weekend or holiday).
For purposes of this analysis, and consistent with NEI 12-01 assumption
- 4, 360 minutes (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) will be used as the time period for the conduct of on-shift ERO response actions. 10 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER NEI 12-06 Assumptions

METHODOLOGY An assessment of on-shift staffing was performed using NEI 12-01, NEI 12-06 and NEI 10-05 guidance.
Subject matter_ experts were assembled to provide analysis support. The assessment was conducted via a tabletop procedural analysis using DAEC procedures to determine iftasks have been sufficiently analyzed for performance by the minimum on-shift staff as designated in the Emergency Plan as allowed by NEI 12-06. The following provides a summary of the process that was used. Each on-shift position from Emergency Plan Section 'B' Emergency Response Organization TABLE B-1 and any additional administrative on-shift position were entered in NEI 10-05 Appendix 1, Table 1. For position titles with more than one position holder, a unique sequential number was assigned to each position.
The site emergency plan reference that
- describes the requirement for the position to be on-shift was then entered into column 3 of Appendix 1, NEI 10-05 Table 1. Firefighting was not applicable for this assessment.
Using only the on-shift positions entered in the table, the following Appendix 1 tables were completed by entering the shift position that fills a described role, or performs a specific function or tasks:

For _each position, the table number and associated line number was then entered in column 4, "Role in Table#/Line#".
If the associated task required additional actions, a "Yes" was placed in the last column and the additional action recorded in the results section ofthis report. The On-Shift Staffing Assessment (OSA) was conducted using the following process: 1. Selection of_ the multi-disciplined work group 2. Scheduling the tabletop at the DAEC Operations support Center (OSC) to allow ready access to required procedures and administrative documents
- 3. Conduct of a pre-jolJ briefing outlining the requirements of NEI 12-01, NEI 12-06 and NEI 10-05 4. Review of the event initial conditions and assumptions*
- 5. Performance of the procedural analysis 6. Documentation of the results of the tabletop by Fukushima project group using the NEI 10-05 forms modified to extend to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This review provided the team with a basic understanding of the event and resulting emergency classifications.
The SRO reviewed EOP, AOP and SAMP actions and identified them to the team. The procedures for FLEX strategies are in draft status which is adequate for a staffing assessment.
When the procedures are finalized a review of the staffing assessment will be performed to ensure that the staffing assessment results have not changed. This activity is tracked by AR 2126130. Resources needed to perform the initial and transition phase response actions were identified from the EOP, AOP, or SAMP procedures and documented.
The team determined when other on-shift resources, such as the RP or Chemistry Technician, would be required and identified 14 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER the time required to perform expected emergency plan functions.
This information was documented on the applicable tables in this report. Finally, the on-shift resources and their actions were summarized in the tables using the NEI 10-05 documentation process in Appendix 1, NEI 10-05 Table 1. One scenario, ELAP with loss of Ultimate Heat Sink was reviewed.
15 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER Security Considerations Existing emergency procedures do not require the use of Security Officers to perform duties unrelated to their assigned roles. However, planned mitigation strategies require Members of the Security Force (MSF) to perform duties unrelated to their assigned roles, (e.g., debris removal and equipment staging).
Security Officers will perform functions within their current roles such as monitoring, damage assessment and controlling sites access and providing compensating measures for any vital area doors that may need to remain open to facilitate room environmental conditions and hose and personnel passage. To the extent practical; security posture and security functions will be relaxed to facilitate immediate onsite and offsite response to the emergency.
No additional events or failures are assumed to occur prior to or during a BDBEE including security events. In preparation for response to an ELAP and a LUHS an alternative security_approach has been developed.
This alternative approach will enable event mitigation, while ensuring a level of protection appropriate for the circumstance.
This approach is a site specific plan which includes elements such as establishing unassisted access for event mitigation and providing security personnel to assist with event mitigation.
The site security department will be trained and prepared to implement the alternative approach when properly authorized.
This training activity is tracked by AR 1744135-24.
Security personnel shall be the last group requested for assistance and the first group relieved once additional emergency response personnel arrive onsite. Security positions selected for reassignment to FLEX response activities are tiered and sequenced and consider position reassignment impacts to security responses under the protective strategy from the "least impactful".
This is in line with the NRC guidance for an ELAP event for reassigning Security officers to FLEX response activities.
Site specific staffing assessments have estimated that 28 MSFs will be trained as FLEX Auxiliary Responders and will be responsible for debris removal from travel paths, transporting onsite portable equipment to staged locations, and assisting in deployment of hoses and cables. Of the possible 5 shift responders, 2 will be assigned per shift as FLEX Auxiliary Responders, -available as needed for postulated beyond design basis events. 16 FUKUSHIMA RESPONSE NEI 12-01PHASE2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER DAEC responses to Staffing Assessment Questions Related to Use of Security Personnel during a BOB Event Response 1.
- How has the site evaluated the use of on-shift personnel (excluding security) to address staffing and the movement of equipment for a beyond design basis event in phases 1, 2, and 3 mitigating strategies?
DAEC Response:
The site has evaluated the use of on-shift personnel (excluding security) to address staffing and the movement of equipment for a beyond design basis event in phases 1, 2, and 3 mitigating strategies in accordance with the NRC staff-endorsed guidance contained in NEI 12-01, Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communications Capabilities.
NOTE -The Mitigating Order and NRC JLD-ISG-2012-01 refers to' Phases 1, 2 and 3 as the Initial Phase, Transition Pbase and Final Phase, respectively.
- 2. All apparent immediate actions taken to address the condition without the use of security (e.g., the exhaustive use of other site personnel).
a.) How is "immediately" defined for the use of security personnel to support the site event? DAEC Response:
Immediately is defined as the moment at which the senior license operator in the Control Room determines that an event has occurred, or plant conditions are present, which will require implementation of Severe Accident Management procedures (e.g., deployment of Initial Phase and/or Transition Phase Mitigating strategies).
17 FUKUSHIMA RESPONSE NEI 12-01PHASE2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER b.) What are the other actions that may be taken before using 10 CFR 73.SS(p)?
DAEC Response:
Through implementation of the appropriate procedures and guidelines, Control Room operators will select the appropriate mitigating strategies for responding to the post-event plant conditions, and direct the performance of the in-field/plant actions necessary to implement these strategies.
Consistent with the goal of protecting public health and safety, implementation of strategies will utilize the site staff in such a way as to ensure that equipment retrieval and operation occurs within the timeframes necessary to maintain safety functions.
- 3. Is the site considering the use of security personnel for other beyond design basis events that are not characterized by the conditions outlined within the guidance document?
If so what are these events and the associated rationale for using security personnel?
DAEC Response:
No; the site is not considering the use of Security personnel for other beyor:id design basis events that are not characterized by the conditions outlined within the , guidance document.
- 4. Technical information concerning why the use of Security P.ersonnel would address the condition.
DAEC response:
The use of security personnel would address the condition because of their availability as a response resource to the Control Room and will help to ensure that mitigating strategies are implemented within the timeframes necessary to maintain safety functions.
Such implementation will preclude or minimize offsite radiological consequences, and thus contribute to the protection of public health and safety. [NOTE: No additional events or failures are assumed to occur immediately prior to or during the event including security events] Security personnel will be supporting implementation of the following event mitigation procedures and guidelines:
- SAMP 724-FLEX Damage Assessment and Portable Equipment Deployment 18 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER 5. If security is used to meet staffing requirements and the placement of equipment, what phase(s) would require their support? DAEC Response:
Security support would be necessary during Phase 1 and Phase 2 (Initial Phase and Transition Phase). 6. The rationale concerning the use of security personnel:
a.) How many secu.rity personnel are necessary to support the event? DAEC Response:
Two (2) security personnel are necessary to support the event. b.) What security requirements in part or total are impacted by the use of the security personnel?
DAEC Response:
An Assessment Table below represents the response to 6b. Non-Safeguards Staffing Assessment Table Position Mitigating Strategy Duty Operate pre-staged heavy equipment and Auxiliary Responder
- 1 perform debris removal. 'May also include assisting plant Operations with deployment of FLEX equipment as necessary.
Operate pre-staged heavy equipment and Auxiliary Responder
- 2 perform debris removal. May also include assisting plant Operations with deployment of FLEX equipment as necessary.
c.) What is the estimated duration for the use of security personnel?
DAEC Response:
Notwithstanding the uncertainties associated with a beyond design basis event, the estimated duration is bounded as stated below. 19 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER
- As noted earlier, the "start time" is the moment at which the senior licensed operator in the Control Room determines that an event has or plant conditions are present, which will require implementation of Severe Accident Management Procedures (e.g., deployment of Initial Phase and/or Transition Phase mitigating strategies).
- With respect to the "end time", it is anticipated that augmented ERO staff would be able to access the site at around 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> following the event. Allowing for some margin in the arrival times of ERO
- personnel, the need to do job briefings and turnovers, the release of security personnel from mitigating strategies duties should occur . during the period of approximately 6 to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the initiating event. d.) What are the duties that will be assigned to security personnel?
DAEC Response:
See response to question 6b, above. The staffing assessment has verified that the designated security personnel do not have non-security related task assignments that would prevent them from performing their mitigating strategy implementation duties (i.e., no assigned collateral duties). Response training for security personnel will be developed in accordance with the guidance in NEI 12-06. e.) What actions will be required to restore security to its normal posture? DAEC Response:
The actions that will allow for dismissal of security personnel from duties associated with implementation of mitigating strategies would be the arrival of a sufficient number of augmented ERO personnel.
Once dismissed, security personnel may resume their normal duties. Appropriate procedures and guidelines will contain instructions to the effect that absent an overriding safety consideration, security personnel will receive priority consideration for mitigating strategy duty relief by the augmented ERO. 7. Is the use of security personnel conducted via a tiered approach to minimize impact to security response capability?
Use of security personnel should be sequenced such 20 FUKUSHIMA RESPONSE NEI 12-01 PHASE 2 STAFFING ASSESSMENT REPORT DUANE ARNOLD ENERGY CENTER that security personnel whose reassignment will adversely
- impact security the least are reassigned first (e.g. use security personnel who are performing admini.strative functions before those who are implementing the protective strategy).
DAEC Response:
Yes; the use of security personnel was determined via a tiered approach to minimize the impact to security response capability.
The selection of personnel considered assigned functions and potential impacts to the protective strategy.
The assignments were .made such that security personnel with the least impact to the protective str;;itegy were reassigned first. The assignment shown in the Table above (response to question 6b) reflects the selection rationale; least to greater impact Strategy Resource Loading Selected SAMPs were reviewed to determine the resources needed and estimated durations of each task associated with the FLEX strategy.
The resources and time frames have been incorporated into Table 2B for ELAP response.
