CURRENT STATUS OF U.S. NUCLEAR REGULATORY COMMISSION INSPECTION MANUAL CHAPTER 0350 PANEL FORT CALHOUN STATION RESTART CHECKLIST AND BASIS DOCUMENTS
Dear Mr. Cortopassi:
The purpose of this letter is to provide the current status of the U.S. Nuclear Regulatory Commission (NRC) actions regarding the items contained in the Restart Checklist, dated February 26, 2013, and the Restart Checklist Basis Document, dated March 7, 2013.
The Restart Checklist describes those actions Omaha Public Power District (OPPD) committed to take prior to the restart of Fort Calhoun Station to address post flood recovery actions, following the Missouri River flood during the summer of 2011, and to address performance issues at the station. The Restart Checklist Basis Document provides 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.
An updated version of both the Restart Checklist and the Restart Checklist Basis Document are enclosed with this letter, and highlights the current status of NRC reviews for the items. The Basis Document includes references to the relevant inspection reports that document our closure of specific items. Closure of the Restart Checklist areas indicates that all inspections related to the area have been satisfactorily completed and the results reviewed by the Inspection Manual Chapter 0350 Panel as acceptable for closure. The remaining items associated with the Restart Checklist are currently under NRC review, with the exception of those items which OPPD is in the process of addressing. Pending the completion of these items, the NRC will perform an independent assessment of the adequacy of OPPD actions.
L. Cortopassi Please direct any questions or comments regarding the enclosures to Michael Hay, Chief, Division of Reactor Projects, Project Branch F at (817) 200-1147.

U.S. Nuclear Regulatory Commission Inspection Manual Chapter 0350 Panel Fort Calhoun Station Restart Checklist Basis Document 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.
Enclosure 2
This Restart Checklist Basis Document describes the areas to be addressed within each Restart Checklist section.
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:

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.
All the security-related items were closed in two inspection reports, 05000285/2013-405 (ML13115A095) and 05000285/2013-407 (ML13213A497).
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 Closed safety culture assessment IR 2013-008 ML13197A261 1.e.2 Methods used by the third-party assessment team to Closed collect and analyze the data were adequate and IR 2013-008 appropriate ML13197A261 1.e.3 Verification that licensees assessment team members Closed were independent and qualified IR 2013-008 ML13197A261 1.e.4 Licensees activities to communicate results of the Closed assessment to various levels of management and staff IR 2013-008 ML13197A261 1.e.5 Licensees corrective actions to the assessment results Closed IR 2013-008 ML13197A261 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 15 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 Closed Performance Deficiency associated with Nuclear IR 2013-008 Safety Culture ML13197A261 1.e.7 Adequacy of extent of condition and extent of causes Closed IR 2013-008 ML13197A261 1.e.8 Adequacy of corrective actions Closed IR 2013-008 ML13197A261 1.e.9 Licensee Assessment of the Fundamental Closed Performance Deficiency associated with Safety IR 2013-008 Conscience Work Environment ML13197A261 1.e.10 Adequacy of extent of condition and extent of causes Closed IR 2013-008 ML13197A261 1.e.11 Adequacy of corrective actions Closed IR 2013-008 ML13197A261 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 Closed Organizational Effectiveness assessment IR 2013-008 ML13197A261 1.f.2 Methods used by assessment team to collect and Closed analyze the data were adequate and appropriate IR 2013-008 ML13197A261 1.f.3 Verification that licensees assessment team members Closed were independent and qualified IR 2013-008 ML13197A261 1.f.4 Licensees activities to communicate results of the Closed assessment to various levels of management and staff IR 2013-008 ML13197A261 1.f.5 Licensees corrective actions to the assessment results Closed IR 2013-008 ML13197A261 The site performed an integrated assessment and identified 15 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 Closed Effectiveness Fundamental Performance Deficiency IR 2013-008 ML13197A261 1.f.7 Adequacy of extent of condition and extent of causes Closed IR 2013-008 ML13197A261 1.f.8 Adequacy of corrective actions Closed IR 2013-008 ML13197A261 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.
This item remains open pending completion of NRC review of the licensees revised root cause and corrective actions for the trend in safety system functional failures.

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 its 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) furnishes 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.

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 elements 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 Closed Exposure Controls IR 2012-011 ML12366A158 5.g.2 IP 71124.02, Occupational ALARA Planning and Closed Controls 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.
