I. BACKGROUND The U.S. Nuclear Regulatory Commission (NRC) is responsible for ensuring that significant events involving reactor and materials facilities licensed by the NRC are investigated in a timely, objective, systematic, and technically sound manner; that the information pertaining to each event is documented; and, that the cause or causes of each event are ascertained. A significant event is any event at an NRC-licensed facility that poses an actual or potential hazard to public health and safety, common defense and security, property, or the environment. The events may prompt reactive inspections by an incident investigation team (IIT), augmented inspection team (AIT), or special inspection team (SIT), depending upon the level of response required. See table 1 for the descriptions of an IIT, AIT, and SIT.

Table 1: Reactive Inspection Teams Description Reactive Inspection Teams Description Incident Investigation Team An IIT consists of technical experts who do not have, and have not had, involvement with licensing and inspection activities at the affected facility. An NRC senior manager leads the IIT. The IIT reports to the Executive Director for Operations.

Augmented Inspection Team An AIT consists of technical experts from the region where the event took place, augmented by personnel from headquarters, other regions, or by contractors.

AIT members may have had prior involvement with licensing and inspection activities at the affected facility. The AIT reports to the Regional Administrator.

Special Inspection Team An SIT consists of technical experts from the region where the event took place and is generally not augmented by personnel from headquarters, other regions, or by contractors. The SIT reports to the Regional Administrator.

Reactive Inspection Screening Process When an event occurs, inspectors use Inspection Procedure 71153, Follow Up of Events and Notices of Enforcement Discretion,1 to assess, gather, and share information about the event with technical experts from the region where the event took place. Information gathered is evaluated against deterministic and risk assessment criteria in Inspection Manual Chapter (IMC) 0309, Reactive Inspection Decision Basis for Reactors.2 Specifically, inspectors and technical experts answer deterministic and risk questions on the Decision Documentation for Reactive Inspection evaluation form. If staff answer yes to any of the deterministic criteria questions, an IMC 0309 risk assessment is conducted. Additionally, if staff answer yes to any deterministic or risk question, the region senior management will make the decision whether to conduct a reactive inspection or follow-up on the event with a baseline inspection. In addition, under IMC 0309, factors such as openness, public interest, transparency, and public safety should be appropriately considered by the NRC when deciding whether to dispatch an IIT, AIT, or SIT.

See Figure 1 for a description of the reactive inspection screening process.

Additionally, see Appendix B for the Decision Documentation for Reactive Inspection evaluation form for deterministic criteria.

2 IMC 0309 provides guidance to the Office of Nuclear Reactor Regulation and the regional staff implementing the requirements prescribed in Management Directive 8.3, NRC Incident Investigation Program. Management Directive (MD) 8.3 is the agency-level governing document for IMC 0309 and includes some of the deterministic and risk criteria for determining the agencys appropriate event response at reactor and material facilities. MD 8.3 also delineates responsibilities at the office level for responding to significant operational events.

Reactive Inspection Evaluations The NRC conducted over 100 reactive inspection evaluations from January 1, 2018, through July 31, 2022.3 Of the 112 evaluations recorded in the Agencywide Documents Access and Management System (ADAMS), 10 resulted in special inspections. Table 2 shows the number of evaluations and reactive inspections by region.

Specifically relating to incidents at operating nuclear power plants, the Office of Nuclear Reactor Regulation (NRR) interfaces with the regional offices that have the lead responsibility for implementing the inspection program. The Division of Reactor Oversight supports the NRRs mission by leading, guiding, and coordinating the activities associated with inspecting and assessing licensee performance at commercial nuclear power plants and evaluating plant events. The regional offices coordinate with the NSIR and the NRR for events warranting consideration of investigation by an AIT or IIT at operating nuclear power plants.

3 During the audit, the OIG identified 28 additional evaluations that were not properly profiled in ADAMS, three of which resulted in special inspections.

II. OBJECTIVE The audit objective was to assess the consistency with which the NRC follows agency guidance for deploying special, augmented, and incident inspection teams in response to safety and security incidents at operating nuclear power plants.

III. FINDINGS The NRC performs reviews of significant operational events. However, it could improve its reactive inspection screening process by:

1. The NRC Should Improve Documentation of Reactive Inspection Decisions and Public Information Sharing The NRC should ensure regional staff complete Decision Documentation for Reactive Inspection forms, consistently profile completed forms in ADAMS, and share reactive inspection decision-making information with the public, whenever possible. However, NRC staff do not:
  • consistently provide sufficient information on the Decision Documentation for Reactive Inspection evaluation forms;
  • consistently profile completed evaluation forms in ADAMS, in accordance with agency guidance; and,

This occurs because NRC guidance lacks clarity on information quality, and varies across the regions. The NRC could improve oversight, efficiency, and instill greater public confidence with higher-quality and more readily accessible information regarding reactive inspection screening.

What Is Required Federal and NRC Guidance Stipulate that the Agency Should Strive to be Transparent and Maintain Reliable Records Management One of the NRCs Principles of Good Regulation is Openness, which comprises the means through which the public will be informed about, and have the opportunity to participate in, the agencys regulatory work.4 Specifically, the openness principle states that communication must be What is internal control?

Internal control is a process used by maintained with Congress, other management to help an entity achieve its government agencies, licensees, and objectives.

the public.

How does internal control work?

Additionally, the U.S. Government Internal control helps an entity:

  • Run its operations efficiently and Accountability Office, Standards for effectively; Internal Control in the Federal
  • Report reliable information about its Government (GAO Green Book),5 operations; and, states that management should use
  • Comply with applicable laws and quality information to achieve the regulations.

entitys objectives. The GAO Green Book also states that management should design control activities to ensure documentation and records are properly managed and maintained.

As relevant here, IMC 0309 and Management Directive (MD) 8.3 require NRC staff to document reactive inspection decisions by placing the evaluation forms in ADAMS.

4 The five Principles of Good Regulation are Independence, Openness, Efficiency, Clarity, and Reliability. The definitions of all the principles are available at NRC Values on the NRC public website. The Commission revised the Mission and Regulatory Philosophy section of the NRCs Five Year Plan for Fiscal Years 1991 through 1995 to promulgate the five Principles of Good Regulation. The principles were then published separately as guidance for the NRC staff from the Chairman. They have since been used by the NRC to drive improvement and by stakeholders to hold the agency accountable.

What We Found Inconsistent Completion and Profiling of Reactive Inspection Evaluation Forms and Limited Public Sharing of Reactive Inspection Decision-Making Information NRC staff do not consistently provide sufficient information on the reactive inspection screening evaluation forms; do not consistently profile completed evaluations forms in ADAMS, in accordance with agency guidance; and, do not share reactive inspection screening decision-making with the public.

Inconsistent Completion of Reactive Inspection Evaluation Forms The OIG analyzed 112 IMC 0309 reactive inspection evaluation forms for commercial power reactor safety and security events completed from January 1, 2018, through July 31, 2022. Specifically, the OIG analyzed each form to determine whether it contained information sufficient for NRC staff and independent reviewers to understand each event and its safety significance. Based on IMC 0309, MD 8.3, and our understanding, each form should include the following information:

  • Background information on what happened and how both the nuclear power reactor and licensee staff responded to the initiating event;
  • Reactor operating modes when the event happened and the nuclear power reactor conditions and related risks;
  • Safety functions of the involved systems, structures, and components;
  • The affected systems, structures, and components information should be described in enough detail to help readers understand the intended functions and safety significance. Additionally, unique features of the nuclear power reactor should be highlighted to minimize errors from extrapolating generic understanding;
  • The technical specifications affected by the incident, because among all the licensing bases, technical specifications are one of the most significant safety requirements for reactor operations. Technical specification violations are often the basis for later escalated enforcement actions; and,
  • Justification details when answering No to the screening questions on the evaluation form. While some of the generic questions may not be applicable or meaningful to the event, applicable questions should be answered with sufficient detail to enable the readers and approver to reach the same conclusion with minimal follow-up engagements.

Table 3 summarizes the results of the OIGs analysis and shows the number of reactive inspection evaluation forms that either provided or did not provide sufficient information (based on the criteria above) in specific categories for screening events at operating nuclear power reactors. In Table 3, Not Applicable represents either security-related information or indicates that question is not relevant to the reactive inspection determination.

Applicable Source: OIG generated based on completed evaluation forms in ADAMS Inconsistent Uploading and Profiling of Completed Evaluation Forms in ADAMS NRC staff should upload and profile all completed reactive inspection evaluation forms in ADAMS. NRC staff do not, however, consistently complete these actions in accordance with agency guidance. For example, the OIG reviewed special inspection reports, searched NRC regional office SharePoint sites that store evaluation forms, and communicated with regional staff to obtain an accurate count of completed evaluation forms. Through these efforts, the OIG found an additional 28 completed evaluation forms that were saved in ADAMS but not profiled correctly. The 28 additional evaluation forms were not profiled in ADAMS as, MD 8.3 Reactive Inspection Evaluation. Correct profiling of completed reactive inspection evaluation forms in ADAMS is important because it allows staff to efficiently search for and retrieve these records.

7

NRC Staff Do Not Share Reactive Inspection Decision-Making Information with the Public In the OIGs review of the 112 evaluation forms plus the additional 28 evaluation forms,6 all except one were uploaded as non-publicly available in ADAMS. Uploading evaluation forms in ADAMS as non-publicly available means the public cannot view the evaluation forms and thus has limited insight into the decision bases for reactive inspections, as well as cases where the NRC opts not to conduct a reactive inspection.

Why This Occurred NRC Guidance Lacks Clarity and Varies Across Regional Offices IMC 0309 does not provide clear guidance about completing the evaluation forms, as well as ADAMS uploading criteria. Additionally, the NRR has a separate guidance document (NRR-123),7 about uploading completed evaluation forms into ADAMS. NRR-123 requires staff to upload the evaluation forms as non-publicly available.

Furthermore, each regional office has its own supplemental guidance for completing the reactive inspection evaluation forms. Additionally, Regions I and II have exclusion lists of events and conditions that would not warrant completing the reactive inspection evaluation form unless they are exacerbated by other issues that contributed to those events and conditions or complexities. For example, the exclusion lists cover:

  • Water hammer events having little or no adverse impact on safety system inoperability;
  • Small fires extinguished that do not challenge fire safe shutdown;
  • Scaffolding found to have potentially impacted only a single safety related system operation;
  • Safety system instrumentation found out of calibration via periodic testing or surveillance;
  • Inadvertent discharge of Freon, fire water, carbon dioxide, or Halon having no adverse impact on plant operations; and,

6 The 28 additional evaluation forms resulted in three special inspections.

Why This Is Important Oversight, Efficiency, and Public Confidence Could be Improved Oversight, efficiency, and public confidence could be improved with higher quality and more readily accessible information regarding reactive inspection screenings. Providing quality information about nuclear power plant safety events helps NRC management make timely and informed decisions about whether to deploy reactive inspection teams. Additionally, providing reactive inspection screening decision-making information to the public aligns with the NRCs organizational goal of being a transparent regulator. However, withholding such information as a matter of practice could adversely affect public confidence in the NRCs public health and safety mission.8 In discussions with the OIG during the audit, NRC managers expressed concerns about changing their practice of withholding reactive inspection decision-making information from the public. Specifically, they stated that sharing this information would not benefit the publics understanding of nuclear safety issues and might raise unnecessary public fear when the agency opts not to conduct a reactive inspection based on an incidents low safety risk significance. However, the evaluation forms would not typically be considered pre-decisional documents9 (by their terms, the forms reflect NRC decisions), and oftentimes the forms do not contain other types of sensitive information. In these cases, there is no apparent basis for the NRCs failure to make the evaluation forms publicly available. Additionally, the failure to publicly share non-sensitive decision-making information can result in the appearance of a lack of transparency when questions arise regarding actions taken by the agency.

Recommendation The OIG recommends that the Executive Director for Operations:

1.1 Update agency policies to require that staff provide complete information on screening evaluation forms, correctly profile evaluation forms in 8 Licensees typically report incidents through 10 Code of Federal Regulations 50.72 Immediate Notification Requirements for Operating Nuclear Power Reactors or 50.73 Licensee Event Report System. These incidents usually result in a MD 8.3 evaluation. Therefore, the public is usually already notified of the incident, and it would be beneficial for the NRC to publicize their review of the incident to enhance the publics confidence in NRCs oversight.

ADAMS, and publicly share non-sensitive reactive inspection screening decision-making, whenever possible.

2. The NRC Should Develop Clear and Consistent Reactive Inspection Screening Guidance The NRC currently does not have clear and consistent reactive inspection screening guidance, and such should be developed. This occurs because the NRC has not recently updated its reactive inspection screening guidance. As a result, the NRCs reactive inspection screening guidance could lead to inconsistencies in screening reactor safety and security events.

What Is Required The NRC Needs Clear and Consistent Reactive Inspection Screening Guidance According to the GAO Green Book, management is responsible for internally communicating the necessary quality information to achieve the entitys objective. The GAO Green Book also states that management should implement control activities through policies, specifically by including periodic reviews of policies, procedures, and related control activities for continued relevance and effectiveness in achieving the entitys objectives or addressing related risks.

Additionally, one of the NRCs Principles of Good Regulation, Clarity, states that agency positions should be readily understood and easily applied.

What We Found The NRC Does Not Have Clear and Consistent Reactive Inspection Screening Guidance NRC staff do not have clear and consistent guidance to ensure reactive inspection screenings related to operating nuclear power reactors are consistent across all NRC regions.

The guidance in MD 8.3 and IMC 0309 lacks clarity and does not provide specific examples to staff. For example, regional office staff expressed their 10

concerns that the deterministic criteria questions on the evaluation form are not risk-informed, and are also overly broad and subjective.10 Therefore, answering the deterministic criteria questions could vary across regions, leading to regional inconsistencies. Additionally, several regional office staff interviewed by the OIG stated that they are confused by the following terminology used in the evaluation form:

  • Significant event vs. significant operational event;
  • Exceeded the design basis;
  • Degraded condition;
  • Loss of safety function;
  • Major deficiency/potential generic safety implication;
  • Repeat failures; and,
  • Licensee operational performance.

Why This Occurred The NRC has Outdated Reactive Inspection Screening Guidance The NRC last updated its primary reactive inspection screening guidance MD 8.3 and IMC 0309in June 2014 and October 2011, respectively.

The NSIR has primary responsibility for MD 8.3, which is an agency-level guidance document applicable to the NRC staffs oversight of commercial power reactors and other regulatory programs. The NSIR established an informal working group to assess and update MD 8.3 in 2020. The working group made minor editorial changes to the directive during this assessment.

However, the working group was also deliberating over other changes to MD 8.3, such as eliminating the term AIT and modifying the deterministic criteria. During our audit, one senior NRC manager stated there was not alignment between MD 8.3 and IMC 0309, and that staff were trying to reconcile differing views. Moreover, the NRR is responsible for implementing MD 8.3, and must wait for a final version of the document before updating IMC 0309.

10 Since 2018, the NRC has solicited staff input through three open Reactor Oversight Process feedback forms. The NRC uses these forms to identify and resolve problems, concerns, or difficulties encountered in implementing its inspection programs. The NRC staffs responses to these forms have highlighted their confusion about the deterministic criteria questions.

11

Why This Is Important Unclear and Outdated Guidance Could Lead to Inconsistent Incident Screening Without controls to ensure guidance is clear and up to date, regional office staff may not readily understand the reactive inspection screening process, and in turn, may not consistently risk-inform their screening of reactor safety incidents. This could lead to inconsistent judgments regarding the appropriateness of reactive inspections following safety incidents at nuclear power plants.

Recommendation The OIG recommends that the Executive Director for Operations:

2.1 Update agency policies so that they provide a well-defined incident screening process with examples for screening reactor safety and security events.

3. The NRC Should Periodically Assess the Effectiveness of Reactive Inspection Screening Guidance The NRC should periodically assess the effectiveness of reactive inspection screening guidance, but it has not done so. This occurs because NRC managers are not aware of the assessment requirement. Periodic effectiveness reviews are important to determine whether inspection screening guidance effectively helps staff meet program objectives.

What Is Required hat Is Require Assess the Effectiveness of Reactive Inspection Screening Guidance IMC 0307, Reactor Oversight Process Self-Assessment, stipulates that staff are required to assess the effectiveness of inspection manual chapters and inspection procedures. Additionally, MD 8.3 states that management is responsible for assessing the effectiveness of incident investigation program activities and recommending actions, as appropriate, to improve the program.

12

What We Found The NRC has Not Assessed the Effectiveness of Reactive Inspection Screening Guidance The NSIR and the NRR, which are responsible for providing reactive inspection screening guidance to agency staff, have not assessed the effectiveness of MD 8.3 and IMC 0309. Staff at three of the four NRC regional offices (regions I, III, and IV) have voluntarily and independently conducted Reactor Oversight Process self-assessments on the implementation of IMC 0309. However, the NRR has not completed a comprehensive review on the implementation of IMC 0309.

Why This Occurred Some NRC Managers are Unaware of Assessment Requirements Not all NRC managers are aware of the assessment requirements for MD 8.3 and IMC 0309. Specifically, the OIG interviewed three managers responsible for assessing the implementation of MD 8.3 and IMC 0309. Two of these managers were not aware of the MD 8.3 assessment requirements.

Why This Is Important Effectiveness Reviews Ensure Guidance Meets Reactor Oversight Process Goals The NRC needs assessments to monitor the effectiveness of reactive inspection screening. Periodic effectiveness reviews can help agency managers assess whether the guidance effectively helps staff screen reactor safety incidents in a consistent, risk-informed manner in accordance with program objectives and higher-level Reactor Oversight Process goals.

Recommendation The OIG recommends that the Executive Director for Operations:

3.1 Periodically assess the effectiveness of MD 8.3 and IMC 0309 implementation.

13

IV. CONSOLIDATED LIST OF RECOMMENDATIONS The OIG recommends that the Executive Director for Operations:

1.1 Update agency policies to require that staff provide complete information on screening evaluation forms, correctly profile evaluation forms in ADAMS, and publicly share non-sensitive reactive inspection screening decision-making, whenever possible; 2.1 Update agency policies so that they provide a well-defined incident screening process with examples for screening reactor safety and security events; and, 3.1 Periodically assess the effectiveness of MD 8.3 and IMC 0309 implementation.

V. NRC COMMENTS The OIG held an exit conference with the agency on May 1, 2023. Before the exit conference, agency management reviewed and provided comments on the discussion draft version of this report, and the OIG discussed these comments with the agency during the conference. Following the conference, agency management stated their general agreement with the findings and recommendations in this report and opted not to provide additional comments. The OIG has incorporated the agencys comments into this report, as appropriate.

Appendix A OBJECTIVE, SCOPE, AND METHODOLOGY Objective The audit objective was to assess the consistency with which the NRC follows agency guidance for deploying special, augmented, and incident inspection teams in response to safety and security incidents at operating nuclear power plants.

Scope This audit focused on the consistency with which the NRC follows agency guidance for screening significant events at operating nuclear power reactors.

The OIG scoped its analysis to focus on operating power reactor incidents because they represent the single largest share of incidents screened, and because power reactor incidents present potentially greater safety and security risks than incidents at non-power reactors and materials facilities.

We conducted this performance audit at NRC headquarters in Rockville, Maryland, from May 2022 to January 2023.

We assessed the reliability of the data by comparing the 112 reactive inspection evaluation forms downloaded from ADAMS to the regional SharePoint sites, special inspection reports, and by confirming with NRC regional offices that the 112 evaluation forms were complete and accurate.

Through these efforts, the OIG identified 28 additional evaluation forms that were not profiled correctly in ADAMS.

Internal controls related to the audit objective were reviewed and analyzed.

Specifically, the OIG reviewed the components of control environment, risk assessments, control activities, information and communication, and monitoring. Within those components, the OIG reviewed the principles of exercise oversight responsibility; establish structure, responsibility and authority; evaluate performance and hold individuals accountable; define objectives and risk tolerances; identify, analyze, and respond to risks; design information system and control activities; implement control activities; use of quality information; communicate internally and externally; and, perform monitoring activities.

16

The OIG conducted analyses to determine whether the agency staff consistently followed reactive inspection screening guidance for evaluating significant events at operating power reactors. The OIG analyzed all 112 reactive inspection evaluation forms conducted between January 1, 2018, and July 31, 2022, for documentation consistency. However, the OIG did not evaluate the additional 28 reactive inspection evaluations forms for documentation consistency because they were not profiled correctly in ADAMS as, MD 8.3 Reactive Inspection Evaluation, and the initial data call.

Additionally, the OIG interviewed NRC staff and management from the NRR, the NSIR, and regional offices to understand how agency staff use MD 8.3 and IMC 0309 to screen incidents at operating nuclear power reactors.

Methodology The OIG reviewed relevant criteria for this audit, including, but not limited to:

  • U.S. Government Accountability Office, Standards for Internal Control in the Federal Government, GAO-14-704G, dated September 2014;

We conducted this performance audit in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives.

Throughout the audit, auditors considered the possibility of fraud, waste, and abuse in the program.

The audit was conducted by Paul Rades, Team Leader; Avinash Jaigobind, Team Leader; Chanel Stridiron, Senior Auditor; Brigit Larsen, Senior Auditor; and, Andy Hon, Senior Technical Advisor.
