SUBJECT:

ISSUANCE OF REVISED U.S. NUCLEAR REGULATORY COMMISSION MANUAL CHAPTER 0350 PANEL FORT CALHOUN STATION RESTART CHECKLIST BASIS DOCUMENT On June 11, 2012, the NRC issued a Confirmatory Action Letter (CAL) documenting the actions that Fort Calhoun Station will take prior to restart to address the issues that resulted in prolonged performance decline. Included in the CAL was the Restart Checklist which listed the specific items that will be reviewed by the NRC.

On November 13, 2012, the enclosed basis document was issued providing details and clarification for the scope and breadth of the Restart Checklist items and the minimum actions that the NRC plans to take to verify that Fort Calhoun Station has adequately addressed the specific items. This is a living document that will be periodically updated to reflect status of inspection activities and when new inspection items are added following MC 0350 Panel review.

Changes to this document will be identified by a change bar as seen below in the next paragraph.

On February 26, 2013, a revised CAL was issued that added items to the Restart Checklist following MC 0350 Panel review. As a result, the enclosed basis document is being revised.

Specifically, as reported by the licensee in the 2012, 3rd quarter Performance Indicator data, the Safety System Functional Failure performance indicator moved into the White region. This item was added to Section 1 of the Restart Checklist, Causes of Significant Performance Deficiencies and Assessment of Organizational Effectiveness. Two items involving the qualifications for containment electrical penetrations and the containment internal structure were added to Section 2.c, Qualification of Containment Electrical Penetrations, and Section 2.d, Containment Internal Structure, respectively, under the element of Flood Restoration and Adequacy of Structures, Systems, and Components. Additionally, several items were added that related to events reported to the NRC involving recently identified equipment problems.

U.S. Nuclear Regulatory Commission Manual Chapter 0350 Panel Fort Calhoun Station Restart Checklist Basis Document, Revision 1 The Restart Checklist is a list of items that require resolution prior to restart. The purpose of the Restart Checklist is to verify the issues that resulted in the prolonged performance decline at Fort Calhoun Station are resolved. The Restart Checklist includes an assessment of each of the key attributes described in NRC Inspection Procedure (IP) 95003, Supplemental Inspection for Repetitive Degraded Cornerstones, Multiple Degraded Cornerstones, Multiple Yellow Inputs or One Red Input.

This basis document provides details and clarification of the scope and breadth of the Restart Checklist items and the actions, at a minimum, that the NRC plans to take to verify Fort Calhoun Station adequately addressed the specific items. These actions that the NRC plans to perform were developed to ensure safe operation of the facility following restart. The Restart Checklist includes broad areas for resolution, including the following items that are described in NRC IP 95003:

• involve inspection findings that were determined to be of more than very low safety significance

• address a cited violation of the facilitys license, technical specifications, or regulations

• concern a loss of ability to maintain and operate the facility in accordance with the design and licensing basis

• address a licensing action that is necessary to be completed prior to restart

• address a failure of licensee management controls to effectively address previous significant concerns to prevent their recurrence (for example, repetitive examples of inadequate root cause evaluations and corrective actions that affect risk-significant equipment and plant operation or both)

The outcomes of the Restart Checklist will provide the NRC a thorough assessment of the causes of the performance decline at Fort Calhoun Station, provide assurance that planned corrective actions are sufficient to address the root causes and contributing causes and to prevent their recurrence, and to verify that adequate qualitative or quantitative measures for determining the effectiveness of the corrective actions are in place. These assessments will be used by the NRC to independently determine if plant personnel, equipment, and processes are ready to support the safe restart and continued safe operation of Fort Calhoun Station.

This basis document is a living document and will be updated as necessary. Any additional significant performance deficiencies identified may be added to the Restart Checklist. Items not requiring resolution prior to restart will be evaluated during the NRCs review of the post-restart sustained improvement plan.

This Restart Checklist Basis Document describes the areas to be addressed within each Restart Checklist section.

Enclosure

Section 1: Causes of Significant Performance Deficiencies and Assessment of Organizational Effectiveness Section 1 of the Restart Checklist contains those items necessary to develop a comprehensive understanding of the root causes of the performance deficiencies identified at Fort Calhoun Station for all greater than green findings. In addition, Section 1 includes the independent safety culture assessment with the associated root causes and findings. The integration of the assessments under Item 1.f will identify the fundamental aspects of organizational performance in the areas of organizational structure and engagement, values, standards, culture, and human behaviors that have resulted in the protracted performance decline and are critical for sustained performance improvement. Section 1 reviews will also include an assessment against appropriate NRC Inspection Procedure 95003 key attributes as described in Section 5.

As additional critical areas for improvement are identified during the root cause evaluations and other assessments, it may be necessary to supplement the Restart Checklist or the Restart Checklist Basis Document to reflect those new items.

Item 1.a Flooding Issue - Yellow Finding Item 1.a is included in the restart checklist for the failure of Fort Calhoun Station to maintain procedures and equipment that protects the plant from the effects of a design basis flood.

These deficiencies resulted in a Yellow (substantial safety significance) finding as documented in NRC Inspection Report 05000285/2010007, (ML102800342). With respect to this finding the NRC will verify that the licensee adequately identifies the root and contributing causes of the risk significant issue; verify that the extent of condition and extent of causes of the risk significant issue are identified, and verify that the corrective actions adequately address the causes to preclude repetition. The following licensee actions will be reviewed by the NRC:

Item Actions to be Verified Prior to Restart Status 1.a.1 Flooding Yellow Finding root and contributing cause evaluation 1.a.2 Flooding Yellow Finding extent of condition and cause evaluation 1.a.3 Flooding Yellow Finding corrective actions addressing root and contributing causes The NRC will verify that the actions related to the Yellow Finding being implemented by the licensee are adequate to support plant restart. These items are listed in the Fort Calhoun Station Flooding and Recovery Action Plan, Revision 3, dated July 9, 2012, and consist of the following:

Action Actions to be Verified Prior to Restart Status Item Number Review / observe all external flood barrier configurations and verify that they have not been altered during flood response or outage 4.2.1.1 activities 4.2.1.2 Issue SO-G-124, Flood Barrier Impairment program Document external flood barrier impairments as applicable in 4.2.1.3 accordance with SO-G-124 Identify flood barriers which will not have adequate qualification 4.2.1.6 basis before leaving Cold Shutdown.

The following NRC open items are specifically related to the Yellow finding and therefore need to be evaluated prior to restart of the facility. For these specific items the NRC will verify that the licensee has performed adequate root cause and extent of condition evaluations related to the associated deficiencies that protect the plant from the effects of a design basis flood. In addition, the NRC will verify that adequate corrective actions were identified associated with the licensees root and contributing causes and extent of condition evaluations and that implementation of these corrective actions are either implemented or appropriately scheduled for implementation.

Information about these findings is located in NRC Inspection Reports 05000285/2011404 (ML111460688) and 05000285/2011406 (ML12108A186).

With respect to these findings, the NRC will verify that the licensee adequately identifies the root and contributing causes of the risk significant issues; verify that the extent of condition and extent of causes of the risk significant issues are identified, and verify that the corrective actions adequately address the causes to preclude repetition.

A description of the security findings and the specific licensee actions to be reviewed by the NRC are contained in a separate document which contains Security Related Information in accordance with 10 CFR 2.390(d)(1) and its disclosure to unauthorized individuals could present a security vulnerability and will not be made publicly available.

Item 1.e Third Party Safety Culture Assessment Item 1.e is included in the restart checklist because the NRC recognizes the importance of nuclear plant licensees establishing and maintaining a strong safety culturea work environment where management and employees are dedicated to putting safety first. In addition, nuclear power plants should have a work environment where employees are encouraged to raise safety concerns, and where concerns are promptly reviewed, given the proper priority based on their potential safety significance, and appropriately resolved with timely feedback to the originator of the concerns and to other employees.

The NRC will assess and inspect the results of the safety culture assessment performed by an organization independent of Fort Calhoun Station. The scope of the inspection related to safety culture will be based on the results of the validation of the licensees third party safety culture assessment and root cause evaluation. The outcome of this item is an NRC graded safety culture assessment. With respect to the licensees third party safety culture assessment the NRC will assess the following items:

Item Actions to be Verified Prior to Restart Status 1.e.1 Verification of comprehensiveness of licensee third party safety culture assessment 1.e.2 Methods used by the third-party assessment team to collect and analyze the data were adequate and appropriate 1.e.3 Verification that licensee=s assessment team members were independent and qualified 1.e.4 Licensees activities to communicate results of the assessment to various levels of management and staff 1.e.5 Licensees corrective actions to the assessment results If substantial weaknesses are identified with the licensees third-party safety culture assessment or the NRC has low confidence in the validity of the licensees results, the NRC will conduct an independent safety culture assessment in order to gain accurate insights on the contribution of weaknesses in safety culture components to licensee performance.

The site performed an integrated assessment and identified fifteen Fundamental Performance Deficiencies (FPDs) that resulted in the overall performance decline at the station. Nuclear Safety Culture and Safety Conscience Work Environment were identified as areas for improvement. With respect to these Fundamental Performance Deficiencies the NRC will assess the following:

Item Actions to Be Verified Prior to Restart Status 1.e.6 Licensee Assessment of the Fundamental Performance Deficiency associated with Nuclear Safety Culture 1.e.7 Adequacy of extent of condition and extent of causes 1.e.8 Adequacy of corrective actions 1.e.9 Licensee Assessment of the Fundamental Performance Deficiency associated with Safety Conscience Work Environment 1.e.10 Adequacy of extent of condition and extent of causes 1.e.11 Adequacy of corrective actions Item 1.f Integrated Organizational Effectiveness Assessment Item 1.f is included on the restart checklist because organizational effectiveness was identified as a potential key contributor to the overall station performance. Organizational effectiveness can impact multiple activities and programs across multiple functional areas at the facility.

At the completion of the assessments performed under Restart Checklist Items 1.a through 1.e, Fort Calhoun Station will integrate the outcomes of each of those assessments to determine what aspects of its organization and human performance need additional focus and improvement. The integration of the root cause and safety culture assessments under Item 1.f will identify those fundamental aspects of organizational performance in the areas of organizational structure and engagement, values, standards, culture and human behaviors that have resulted in the protracted performance decline, and are critical for sustained performance improvement. The licensee will perform this assessment using qualified individuals with independent oversight.

The NRC will review the licensees assessments of organizational effectiveness and any connections to safety culture insights (from Item 1.e). The NRC will ensure that proper corrective actions are established and incorporated to resolve organizational effectiveness issues that adversely affected station performance.

With respect to this item the NRC will review the following:

Item Actions to be Verified Prior to Restart Status 1.f.1 Verification of comprehensiveness of licensee Integrated Organizational Effectiveness assessment 1.f.2 Methods used by assessment team to collect and analyze the data were adequate and appropriate 1.f.3 Verification that licensee=s assessment team members were independent and qualified 1.f.4 Licensees activities to communicate results of the assessment to various levels of management and staff 1.f.5 Licensees corrective actions to the assessment results The site performed an integrated assessment and identified fifteen FPDs that resulted in the overall performance decline at the station. These deficiencies included Leadership/Organizational Effectiveness, Nuclear Safety Culture, Safety Conscious Work Environment, Corrective Action Program, Site Operational Focus, Resource Management, Processes for Meeting Regulatory Requirements, Equipment Reliability/Work Management, Engineering Design/Configuration Control, Performance Improvement, Procedure Quality/Procedure Management, Nuclear Oversight, Emergency Response Organization, and Security.

The licensee identified that the most significant FPD that resulted in performance decline at the station was Leadership/Organizational Effectiveness. Examples included lack of accountability throughout the organization; standards, policies, and administrative controls are outdated, ineffective, and sometimes ignored; programs such as the Corrective Action Program, Maintenance Rule Program, and Equipment Service Life Program, were not managed to a level ensuring station improvement. The NRC will review the adequacy of licensee actions regarding this FPD.

Item Actions to Be Verified Prior to Restart Status 1.f.6 Licensee Assessment of Leadership/Organizational Effectiveness Fundamental Performance Deficiency 1.f.7 Adequacy of extent of condition and extent of causes 1.f.8 Adequacy of corrective actions Item 1.g Safety System Functional Failures White Performance Indicator The Safety System Functional Failure Performance Indicator for the 3rd quarter of 2012 moved into the White region based on a number of events being identified, mainly during the licensees discovery efforts to improve overall safety at the facility. This indicator reflects the number of events or conditions that alone prevented, or could have prevented, the fulfillment of the safety function of structures or systems in the previous four quarters. In the past four quarters, nine functional failures were identified and reported by the licensee.

With respect to these functional failures, the NRC will verify that the licensee adequately identifies the root and contributing causes; verify that the extent of condition and extent of causes are identified, and verify that the corrective actions adequately address the causes.

These events are already captured in this basis document as items that will be reviewed by the NRC. The following table provides a reference to the section in this document where these items are addressed:

The review is structured consistent with NRC Inspection Procedure 95003 (Sections 02.03 and 03.03), and is accomplished by review in the six key attributes.

The selected systems for detailed review (vertical slice) as part of the Reactor Safety Strategic Performance Area were based on their high risk significance, input from system health reports, performance indicators, condition reports, and licensee event reports. Teams of Omaha Public Power District and independent external experts will perform the Reactor Safety Strategic Performance Area reviews.

Systems selected are:

• AC and DC Electrical Distribution Systems. These systems include the 4160V breakers, 480V breakers, batteries, and battery chargers. Electrical distribution systems at Fort Calhoun Station provide necessary power for Mitigating Systems. The AC and DC systems provide power to key pumps, motors, valves, and instruments required to monitor and respond to plant conditions. From the plants probabilistic assessment, the AC and DC electrical systems account for a substantial portion of plant risk. The electrical distribution system was selected for self assessment by the licensee based on both identified issues and their importance to safety.

• High Pressure Injection System. This system is important to provide mitigation for postulated accident conditions in the reactor plant. This review will assess and validate key aspects of the suction and discharge pathways, system alignments, power sources, and emergency actuation.

• The Emergency Diesel Generator System (EDGs) furnish a reliable source of 4160V AC power for safe plant shutdown and operation of engineered safeguards when the normal sources of off-site power are lost. The EDGs are safety related and are required to mitigate the consequences of events that have the potential to cause a release of radioactivity. The emergency diesel generators function as an emergency power source during all phases of reactor operation.

• The Reactor Protection System (RPS) is designed to rapidly shut down the nuclear chain reaction prior to reaching a condition that could damage the reactor core.

The NRC will assess the adequacy for each of the licensees detailed reviews and select samples for independent verification that the licensee properly assessed each system.

NRC inspections activities and site assessment activities have determined that Fort Calhoun Station did not consistently conduct adequate Operability Evaluations to ensure that the impacts of degraded conditions on plant operations are fully understood. Additionally, NRC inspection determined that some equipment identified as operable but degraded remained degraded until subsequent failure occurred. Fort Calhoun Station processes did not adequately identify degraded equipment or restore equipment from a degraded condition to full qualifications in a timely manner.

The site performed an integrated assessment and identified fifteen Fundamental Performance Deficiencies that resulted in the overall performance decline at the station. One of the deficiencies identified was Processes to Meet Regulatory Requirements. Examples in this area included the site does not consistently recognize degraded-nonconforming conditions; and operability determinations and functional assessments are not sufficiently rigorous.

The NRC will evaluate the effectiveness of the licensees assessment of the Operability Determination Process, extent of condition and extent of causal analysis, and adequacy of associated corrective actions.

Item Actions to Be Verified Prior to Restart Status 3.e.1 Licensee Assessment of the Fundamental Performance Deficiency associated with Processes to Meet Regulatory Requirements specifically related to the Operability Determination Process 3.e.2 Adequacy of extent of condition and extent of causes 3.e.3 Adequacy of corrective actions Item 3.f Quality Assurance Quality Assurance is an important program at nuclear power plants. It is designed to be an independent group that assesses plant workers in the performance of a broad range of safety-related work or evaluations. Through quality assurance assessments or audits, problems and tends can be identified before they become significant plant problems.

The site performed an integrated assessment and identified fifteen Fundamental Performance Deficiencies that resulted in the overall performance decline at the station. One of these deficiencies involved the effectiveness of Nuclear Oversight (NOS). Examples included NOS did not identify many of the substantive issues that have resulted in the decline in station performance; NOS has not performed critical and intrusive reviews focused on behaviors; NOS neither collected nor integrated performance data from line organizations; and issues identified by NOS are not communicated in a manner that compels site leaders to act.

The NRC will review the adequacy of the licensees assessment, extent of condition and causes, and corrective actions being implemented to improve performance of the Nuclear Oversight function. This will include a review of the Quality Assurance processes and a review of sampled assessments or audits performed by the Quality Assurance department. In addition, the NRC will assess the effectiveness of the oversight provided by the Safety Audit and Review Committee.

Item Actions to Be Verified Prior to Restart Status 3.f.1 Licensee assessment of the Fundamental Performance Deficiency associated with Nuclear Oversight effectiveness 3.f.2 Adequacy of extent of condition and extent of causes 3.f.3 Adequacy of corrective actions 3.f.4 Adequacy of recent Nuclear Oversight audits 3.f.5 Effectiveness of Safety Audit and Review Committee Section 4: Review of Integrated Performance Improvement Plan Section 4 of the Restart Checklist is provided to assess Fort Calhoun Stations Integrated Performance Improvement Plan. OPPD has docketed the Integrated Performance Improvement Plan, which details the plans and actions needed to address the conditions that transitioned FCS to NRC oversight under IMC 0350.

The Integrated Performance Improvement Plan (IPIP) should address pre-restart and post-restart actions. The IPIP should have a sufficient level of detail so that the NRC staff will be capable of developing inspections plans to assess and review the plans actions.

The NRC will review the IPIP and all changes to the IPIP to ensure its pre-startup and post-startup actions and plans are adequate to address the conditions that led to the protracted decline in plant performance.

Item Description Status 4.1 Review of Integrated Performance Improvement Plan Section 5: Assessment of NRC Inspection Procedure 95003 Key Attributes Section 5 of the Restart Checklist is provided to assess the key attributes of NRC Inspection Procedure 95003. The key attributes are listed as separate subsections below. It is intended that the activities in these subsections be conducted in conjunction with reviews and inspections for Sections 1 - 4, rather than a stand-alone review. In addition, the NRC will review the effectiveness of licensee short term and long term corrective actions associated with these areas to ensure they are adequate to support sustained plant performance improvement.

Item 5.a Design The NRC will independently assess the extent of risk significant design issues. The review will cover the as-built design features of the auxiliary feedwater system. This review will verify its capability to perform its intended functions with a sufficient margin of safety. The basis for selecting the auxiliary feedwater system was its high risk significance in the specific individual plant evaluation, and input from system health reports, performance indicators, condition reports, and licensee event reports. Focus will be on modifications rather than original system design. Information from this inspection will be used to assess the licensees ability to maintain and operate the facility in accordance with the design basis. The NRC review includes the following:

• assessment of effectiveness of corrective actions for deficiencies involving design

• selection of several modifications to the auxiliary feedwater system to determine if the system is capable of functioningas specified by the current design and licensing documents, regulatory requirements, and commitments for the facility

• determination if the auxiliary feedwater system is operated consistent with the design and licensing documents

• evaluation of the interfaces between engineering, plant operations, maintenance, and plant support groups Item Description Status 5.a.1 Perform NRC design engineering team inspection of the Auxiliary Feedwater System The site performed an integrated assessment and identified fifteen Fundamental Performance Deficiencies that resulted in the overall performance decline at the station. One of the deficiencies identified was Engineering Design/Configuration Control. Examples in this area included changes to plant configuration and design and licensing basis are not effectively analyzed, controlled, and implemented; incomplete documentation and poorly written justifications in modification packages; and evaluations of fit, form, and function have been inadequate.

The NRC will evaluate the thoroughness of the licensees Engineering Design/Configuration Control assessment, adequacy of extent of condition and extent of causal analysis, and adequacy of associated corrective actions.

The facility is required to maintain fixed and portable radiation survey equipment (for airborne and external hazards), respiratory protection, communication equipment, temporary ventilation and shielding, and anti-contamination clothing to protect workers. This equipment is also needed to conduct adequate radiation monitoring and surveillance activities. Routine calibration and maintenance of this equipment ensures its continued operability. The NRC will inspect and assess the plant facilities, equipment, and instrumentation for occupational radiation safety.

Worker performance has an obvious, important impact on work activities in radiological areas.

Two of the major components are health physics technician and general radiation worker (crafts) groups. Human performance is impacted by several vital factors - qualification and training. The selection, qualification, and training requirements for facility personnel are generally governed by a licensing commitment in the plant technical specifications (to an American Nuclear Society standard). The NRC will inspect and assess the human performance attributes of occupational radiation safety.

The following NRC Inspection Procedures will be implemented:

Item Description Status 5.g.1 IP 71124.01, Radiological Hazard Assessment and Completed Exposure Controls IR 2012-011 ML12366A158 5.g.2 IP 71124.02, Occupational ALARA Planning and Controls Completed IR 2012-011 ML12366A158 Item 5.h Public Radiation Safety To prevent the inadvertent release of licensed radioactive material from the licensees control requires the use of sensitive radiation survey equipment that is properly setup and calibrated.

The NRC will assess and inspect the plant equipment, systems, and instrumentation of public radiation safety.

The performance of radiation surveys on equipment and material to be released from the licensees facility requires appropriate policy and technical procedural guidance for handling and processing a wide variety of potentially contaminated materials. The NRC will inspect and assess the procedures and programs of public radiation safety.

Human performance can directly affect radioactive waste processing, radioactive effluent processing, and transportation programs. It is important to ensure that plant workers are adequately trained and qualified to perform their job function. Periodic retraining is also needed to ensure that workers maintain their qualifications and are updated with new information and requirements. The NRC will inspect and assess the human performance elements of public radiation safety.

The following NRC Inspection Procedures will be implemented:

Item 6.b Review of Licensing Commitments Necessary for Restart The NRC will conduct a commitment management audit, focusing on the implementation of regulatory commitments.

Item Description Status 6.b.1 Perform commitment management audit Section 7: Readiness for Restart Fort Calhoun Station has been shut down for a prolonged period of time (since April 2011). This section is provided to ensure final restart items are appropriately addressed to allow for power operation to recommence.

Item 7.a Operations Organization Ready for Restart After long periods in a shutdown condition, particularly where significant performance issues were also identified, a performance-based and risk-informed inspection should be conducted by the NRC. The NRC performs such inspections using Operational Readiness Assessment Team inspections, under the guidance of Inspection Procedure 93806, Operational Readiness Assessment Team Inspections. The NRC plans to perform an operational readiness inspection during plant heat up prior to start up to assess operational performance.

Item Description Status 7.a.1 Perform Operational Readiness Assessment Team inspection The site performed an integrated assessment and identified fifteen Fundamental Performance Deficiencies that resulted in the overall performance decline at the station. Site Operational Focus was identified as one of these areas for improvement. Examples identified by the licensee included decisions do not demonstrate the use of a systematic process; station personnel lack understanding of the design and licensing basis of the plant in a manner that drives conservative, operational decision making; inconsistent recognition and evaluation of risk significant conditions; and excessive backlogs in preventative maintenance, surveillances, procedure revisions, drawing changes, corrective maintenance, and low margin issues.

The NRC will evaluate the thoroughness of the licensees evaluation involving Site Operational Focus, adequacy of extent of condition and extent of causal analysis, and adequacy of associated corrective actions.

Item Description Status 7.a.2 Licensee Assessment of the Fundamental Performance Deficiency associated with Site Operational Focus 7.a.3 Adequacy of extent of condition and extent of causes 7.a.4 Adequacy of corrective actions Item 7.b Systems Ready for Restart and Mode Restraints Properly Addressed This item is a final review, by the NRC, of system lineups and preparations for restart. This will also include a specific review of how Fort Calhoun Station addressed, reviewed, and closed particular mode restraints.

Item Description Status 7.b.1 Final system readiness and mode restraint review Item 7.c Final Review of Corrective Action Program for Restart Items This item is a final NRC review of the Corrective Action Program actions that were required prior to facility restart. The NRC will inspect to ensure corrective actions associated with equipment operability, design, or qualification were appropriately addressed and closed prior to restart, or that they are specifically tied to a restart or mode restraint.

Item Description Status 7.c.1 Final corrective action program review for restart items prior to restart Section 8: Confirmatory Action Letter Resolution Item 8.a Verification that all Restart-Related Confirmatory Action Letter Items are Appropriately Resolved The NRC will inspect and independently verify that the required actions in the Confirmatory Action Letter are completed prior to restart.

Item Description Status 8.a.1 All Confirmatory Action Letter items addressed Item 8.b Conduct Public Meeting Regarding Plant Readiness for Restart Item Description Status 8.b.1 Conduct public meeting to discuss plant readiness for restart Section 9: Final Recommendation for Restart Item 9.a Final Recommendation for Restart If warranted, the Manual Chapter 0350 Panel recommends restart to the Region IV Administrator. The Region IV Administrator obtains concurrence for restart from the Deputy Executive Director for Reactor and Preparedness Programs, and the Director of the Office of Nuclear Reactor Regulation. Plant restart will be recommended when the NRC has determined that Fort Calhoun Station can operate safely, and has completed the required sections of the Confirmatory Action Letter and Restart Checklist.
