Abstract

The handbook describes the procedures for reporting material ev ents to the NRC. The handbook includes what events are required to be reported, the level of detail, and how to report. A distinction is made between reporting events to the N RC Headquarters Operation Center (HOC) and written reports. Written reports are submitted to the Nuclear Material Event Database (NMED). Reporting of Agreement State nuclear material licensee events to the NRC is mandatory for purposes of compatibility.

The review and analysis of operational event information increa ses the effectiveness of the U.S. Nuclear Regulatory Commission (NRC) and Agreement State re gulatory programs by identifying safety-and security-significant events, and their causes. The information from reports of medical events, overexposures, equipment failures, and other events that have occurred involving the use of nuclear materials licensed by either the N RC or the Agreement States is invaluable in assessing trends or patterns and identifying poss ible inadequacies or unreliability of specific equipment or procedures. The reported information w ill aid in understanding why the events occurred and identify any actions necessary to prevent r ecurrence, improve the effectiveness of the NRC and Agreement States regulatory progr ams, and ensure public health and safety. The information is also used in preparation of the NRCs annual report to Congress on abnormal occurrences, and to support the United States comm itment to report to the International Atomic Energy Agencys international database of significant events. Information is also provided on obtaining Federal assistance for radiological emergencies.

This handbook has been revised to provide clear information and instruction to the staff of the Agreement States that are responsible for the preparation of re ports for events involving the use of nuclear materials that occurred in their State. Based on the regulation associated with the type of event, Agreement States will need to notify the HOC of the event and/or submit a written report to NMED. Further direction will be provided in this hand book.

1 INTRODUCTION

This handbook contains guidance for Agreement States on reporti ng nuclear material events that occurred in their State to the U. S. Nuclear Regula tory Commission (NRC).

The objectives of this handbook are to improve technical inform ation, standardize format, ensure consistency, and facilitate information retrieva l.

The NRC collects information on events to:

a. Assess the events against the Abnormal Occurrence (AO) crite ria and report to the U.S.

Congress as required by the Energy Reorganization Act of 1974.

b. Assess the events (except medical events) against the Intern ational Atomic Energy Agency (IAEA) International Nuclear Event Scale (INES) to parti cipate in international reporting.

c. Perform operating experience assessments and evaluate for ge neric applicability, including generic issues, to ensure that any safety significant issues are shared with the National Materials Program.

2 BACKGROUND

2.1 Federal Statutes

The Atomic Energy Act of 1954 (Public Law (P.L.)83-703) (AEA), Section 274, Cooperation with States, allows States to assume regulatory a uthority over byproduct, source and/or certain quantities of special nuclear materials. The AEA directs NRC to cooperate with the States in the formulation of standards to pr otect employees or the general public against hazards of radiation and to assure that State and Commission programs will be coordinated and compatible.

The Energy Reorganization Act of 1974 (P.L.93-438) (ERA), Sect ion 208, Abnormal Occurrence Reports, requires the NRC to provide information on events that meet the AO criteria to Congress on an annual basis.

Under the Government Performance and Results Act Modernization Act of 2010 (P.L. 111-352), federal agencies are required to compare actual performance achieved with the performance goals established in the agency strategic plan. The NRC maintains NUREG-1614, Strategic Plan, and NUREG-1100, Performance Budg et/

Congressional Budget Justification. Event coordination is use d to demonstrate the ability to ensure the safe and secure use of radioactive materi als.

2.2 Commission Policy Statements

The Commission adopted the policy statement Criteria for Guida nce of States and NRC in Discontinuance of NRC Regulatory Authority and Assumption Th ereof by States Through Agreement (46 FR 7540, January 23, 1981; 48 FR 33376, July 21, 1983),

which describes the specific requirements that a State must mee t for the Commission to approve an Agreement. Specifically, Criterion 26, Relations wi th Federal Government and Other States, states that there should be an interchange of Federal and State Handbook for Nuclear Material Event Reporting for the Page: 2 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

information and assistance in connection with the issuance of r egulations and licenses or authorizations, inspection of licensees, reporting of incidents and violations, and training and education problems. Criteria 26 uses the same lan guage as the original Criteria 26 adopted by the Atomic Energy Commission (AEC) in 19 61.1 The AEC was the predecessor to the NRC.

The Commission first directed NRC staff to make Agreement State reporting of events to NRC an item of compatibility in SRM-SECY-97-054, Final Recommen dations on Policy Statements and Implementing Procedures For: "Statement of Princ iples and Policy for the Agreement State Program" and "Policy Statement on Adequacy and Compatibility of Agreement State Programs," dated June 30, 1997. On May 7, 1998, NRCs Office of State Programs transmitted the All-Agreement State Letter SP-98 -040, Guidance for Reporting Material Events, whi ch included the first final version of SA-300 and the Handbook. SP-98-040 also indicated that the reporting of incide nts and events is now required for compatibility and would be evaluated under Integra ted Materials Performance Evaluation Program (IMPEP).

The Agreement State Programs Policy Statement (82 FR 48535, O ct. 18, 2017)2 also discusses the requirement for Agreement States programs to prov ide acceptable level of protection of public health and safety (adequacy) and ensure th at its program supports an overall nationwide program in radiation protection (compatib ility) by adopting program elements3 to ensure these goals.

2.3 Guidance Documents

Management Directive 5.9 Adequacy and Compatibility of Program Elements for Agreement State Programs describes the six compatibility categ ories (A, B, C, D, NRC, and health and safety (H&S)) for evaluating and classifying pro gram elements. Program elements relating to reporting requirements are used an example s of compatibility category C.4

A Program Element Table and Associated Compatibility Categorie s as Noted in SA-

1 Criteria for Guidance of States and AEC in Discontinuance of AEC Regulatory Authority and Assumption Thereof by States Through Agreement 26 FR 2536; March 24, 1961.

2 The Agreement State Programs Policy Statement consolidates and supersedes two previous policy statements "Statement of Principles and Policies for the Agreement State Program," and "Policy Statement on Adequacy and Compatibility of the Agreement State Programs, (62 FR 46517; September 3, 1997).

3 Agreement State Programs Policy Statement (82 FR 48535, 48538) Oct. 18, 2017). The policy statement defines program element to mean any component or function of a radiation control regulatory program, including regulations and other legally binding requirements imposed on regulated persons, which contributes to implementation of that program.

4 Management Directive 5.9 Adequacy and Compatibility of Program Elements for Agreement State Programs (April 26, 2018) at pg. 6-7. To be included in Compatibility Category C, an NRC program element must relate to regulatory areas that could create conflicts, duplications, gaps, or other conditions that would jeopardize an orderly pattern in the regulation of agreement material on a nationwide basis if not implemented by an Agreement State. Such Agreement State Program elements shall embody the essential objective of the corresponding NRC program element and, if not implemented, would result in an undesirable consequence.

Handbook for Nuclear Material Event Reporting for the Page: 3 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

2005 lists the compatibility designation for regulatory6 and non-regulatory program elements that States must adopt. The program elements related t o Event and Allegation Response Procedures, Event Reporting Procedures and Wrongdoing Investigation Procedures are designated compatibility category C. 7 The program element Event Reporting to the NRC is designated compatibility category B. 8

The Agreement States report nuclear material events to the NRC in accordance with interim SA-300 Reporting Material Events (ML21165A163) and SA -300 Handbook on Nuclear Material Event Reporting in Agreement States (revised i nterim)

(ML22266A093) or equivalent procedures. The procedures in SA-3 00 are considered a program element and consequently, a matter of compatibility C. As an item of compatibility, the Agreement States must provide nuclear materi al event reports to the NRC.

The reporting of events to the NRC are evaluated during an IMPE P review under the performance indicator Technical Quality of Incidents and Alleg ations Activities. (See SA-105 Reviewing the Common Performance Indicator, Technical Q uality of Incident9 and Allegation Actions (ML20196L417) and MD 5.6 Integrated Mat erials Performance Evaluation Program (IMPEP) (ML19213A024) for further informatio n on these subjects.)

The Agreement States will be evaluated against the ability to c onduct the following:

3 REPORTING MATERIAL EVENTS

Agreement States shall report to the NRC all events reported to them in accordance with their State regulations that are compatible to NRCs reporting requirements. The NRC evaluates material events reporting under IMPEP.

The NRC reporting regulations are provided in Title 10 of the U.S. Code of Federal Regulations (10 CFR) and Appendix A, NRC Reporting Requirements. Appendi x A lists the reporting requirements for the nuclear material events and provides brief descriptions of the reporting requirements, the timeliness metr ic, and where to report.

This Handbook uses the term, written report, for consistency. Written reports are submitted to NMED. For the purposes of this handbook, the terms written report and NMED report may be used interchangeably.

5 The table can be found on the Regulation Toolbox of the state communications portal Web site at:

https://scp.nrc.gov/regtoolbox.html for both regulation and non-regulation program elements 6 Id. Licensees are required to report nuclear material events in accordance with Title 10 of the U.S. Code of Federal Regulations (10 CFR) Parts 20, 30, 31, 34, 35, 36, 37, 39, 40, 70, and 71, specified in Appendix A below, or equivalent state regulations to their respective Agreement State regulatory agency.

7 Id. at pg. 5 and 6.

8 Id.at pg. 6. Program elements in Compatibility Category B are those that apply to activities that cross jurisdictional boundaries. These program elements have a particular impact on public health and safety and need to be adopted in an essentially identical manner in order to ensure uniformity of regulation on a nationwide basis.

9 The term "incident" means an event or condition that has the possibility of affecting public health and safety such as overexposure, damage to equipment or facility, release of radioactive material, equipment, or procedure failure, lost/stolen/abandoned radioactive material, leaking source, contamination event, transportation, loss of control, medical event, etc. If an Agreement State defines this term in a different fashion, this should be noted during the IMPEP review.

Handbook for Nuclear Material Event Reporting for the Page: 4 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

Agreement States shall report events to the NRC in the manner t hat is described in Appendix A. The icons in Appendix A indicate whether the report ing requirement specifies a report to the HOC or a written report. The Agreemen t States should consult with their Regional State Agreements Officer (RSAO) if they are unsure. A list of RSAOs is included on the NRC NMSS Office Directory at https://scp.nrc.gov/stpdirectr.html.

Appendix B, Reporting Methods and Contact Information, contai ns a summary of the methods available for contacting the NRC, National Response Center, and other regulatory agencies.

3.1 Timeliness

Agreement States shall notify the NRC on the same timeframe tha t licensees notify the Agreement State. (See Appendix A for reporting timeframes.) For example, if the NRC reporting requirement specifies 24-hour notification, then the licensee shall notify the Agreement State in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , and the Agreement State shall noti fy the NRC within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of receiving the notification from the licensee. In insta nces where the NRC reporting requirement specifies immediate and as soon as pos sible (ASAP), the NRC accepts Agreement State reporting on that business day. In inst ances where the NRC reporting requirement specifies on the next calendar day, the NRC accepts Agreement State reporting on the next business day. This timeliness met ric is reviewed during IMPEP reviews.

If the Agreement State receives an allegation that also meets t he reporting requirements, the Agreement State shall not report it. The time liness clock for event reporting does not start. The Agreement State should assess the concern in their allegation program. The Agreement State should assess the conce rn again after it was processed by the allegation program to determine if it meets th e reporting requirements.

3.2 Event Report Identification Number

The Agreement State shall assign and reference an Event Report Identification Number for all reports made to the HOC and all written reports. The Ev ent Report Identification Number shall consist of the two letter State agency ID, two-dig it year corresponding to the reporting year, and a sequentially assigned four-digit ID n umber.

3.3 Reports to the HOC

For immediate reports and 24-hour reports, the Agreement States shall report events to the HOC. The Agreement States should email the reports to the H OC, however any of the following communication types are acceptable:

Email: HOO.HOC@nrc.gov

Telephone: (301)-816-5100

Fax number: (301)-816-5151

When submitting an event report to the HOC, provide as much inf ormation as is known at the time the report is prepared. The HOC will request additi onal information, as needed, and will process any additional information as updates. Agreement States shall assign and provide an Event Report Identification Number for ea ch reported event.

Handbook for Nuclear Material Event Reporting for the Page: 5 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

After the event report to the HOC is completed, the Agreement S tate shall determine whether a written report is also required and verify the associ ated timeframe in Appendix A.

The Agreement States may voluntarily report an occurrence to th e HOC that they believe has safety significance, generic interest, or involves media interest. The Agreement State should describe the situation and provide any e xplanation of why they are reporting. The HOC shares the information with NMSS with a Logbook Entry.

3.4 Written Reports

The expectations are to ensure that the event is reported in a timely manner with as much information as possible. As new information is obtained, this information should be provided to NMED (preferred method) or to the NRC as soon as possible (See Section 3.4.3 below).

Agreement States shall submit written reports to NMED (preferre d method) or to the NRC when specified in Appendix A. In some cases, the written re port is required to be submitted within a timeframe after the report to the HOC is mad e. In other cases, the written report is the only reporting that is required by Append ix A.

The Agreement States shall provide as much information as is kn own at the time the written report is prepared. A written report should be comprehe nsive and easy to understand. Appendix C, Minimum Required Event Information, p rovides a list of the minimum event information to be provided. Written reports may b e incomplete if the investigation and/or follow-up actions are not completed within the timeframe provided in the reporting requirements. In those cases, Agreement States sh all provide follow-up written reports later.

3.4.1 Sensitive Information

Personal or sensitive information should not be included in wri tten reports (e.g., names, personal addresses, or social security-numbers). Do not include security-related sensitive unclassified non-safeguards information. If such info rmation is required to describe the event, the Agreement State shall provide a bracket ed copy of the information that identifies the information to be protected and a redacted copy of the information that deletes such information. Additional guidance is included in NRC Regulatory Issue Summary (RIS) 2005-031 Revision 1, Control of Security-Related Sensitive Unclassified Non-sa feguards Information Handled by Individuals, Firms, and Entities Subject to NRC Regulation of the Use of Source, Byprod uct, And Special Nuclear Material.

3.4.2 Units

All event reports should include the international system of un its (SI system) as well as conventional units. Include the SI units first with the convent ional unit equivalent following in parentheses (e.g., 730 megabecquerel (MBq) (20.4 m Ci)).

Spell out the dose unit the first time it appears and then cont inue with an abbreviation.

Handbook for Nuclear Material Event Reporting for the Page: 6 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

For example, a dose should be described as 1,000 centiGray (cGy ) (1,000 rad) the first time and continue with 1,000 cGy (1,000 rad).

3.4.3 Submission Methods for Written Reports

Based on the regulation associated with the type of event, Agre ement States will need to submit a written report. Agreement States may submit a written report to NMED (preferred option) or to the NRC. Agreement States have the op tion of using NMED, email, or the mail to submit their written reports. Submitting written reports electronically is the most time-efficient option. When creating a written repo rt, NMED allows users to create a file (report) to either upload or email.

a. Submit the written reports electronically using the document Upload function in NMED;

b. Email an attached file to NMED@inl.gov; or

c. Submit through mail and include a cover page (see Table B.5 in Appendix B) to ensure that the written report is handled appropriately by the Document Control Desk staff. Written reports submitted through the mail shall be in a n optical character recognition format.

Address the mail to:

Director Division of Materials Safety, Security, State, and Tribal Programs Office of Nuclear Material Safety and Safeguards U.S. Nuclear Regulatory Commission 11545 Rockville Pike Rockville, MD 20852-2738 Attention: Chief, Medical Safety & Events Assessment Branch, Mail Stop T5B60

For this option, the NRC will send the written report to the NM ED contractor and the NMED contractor will add the NMED report to NMED.

3.4.4 Follow-up Written Reports

After submitting the initial written report, the Agreement Stat es shall determine if the NMED record includes the minimum required event information as detailed in Appendix C. If additional information is needed or becomes available aft er the initial notification, the Agreement States shall submit follow-up written reports. Fo llow-up written reports should include:

a. The results of investigations as to what, where, when, and h ow the event or conditions occurred.

b. The root cause(s) and/or the corrective actions made to prev ent recurrence, if applicable.

Handbook for Nuclear Material Event Reporting for the Page: 7 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

c. All investigative information obtained through closeout of t he event.

d. The document(s) or clear reference to documents on file that the Agreement State used to generate the NMED record (e.g., a licensee inspection r eport dated mm/dd/yy), if applicable and appropriate.

e. Any follow-up information that revises earlier information o r provides additional information on a given event to ensure a complete historical re cord.

4 REPORTING THEFT OR TERRORIST ACTIVITIES

10 CFR Part 37, Physical Protection of Category 1 and Category 2 Quantities of Radioactive Material, or equivalent Agreement State regulation s, contains, in part, reporting requirements. Licensees are required to immediately n otify their appropriate Local Law Enforcement Agency in cases involving actual or attem pted theft, sabotage, or diversion of radioactive material containing quantities grea ter than or equal to the quantities of concern of radioactive material in accordance wit h 10 CFR 37.57, Reporting of Events, or the equivalent Agreement State regula tion. For the purposes of reporting events for these risk significant radioactive materials, the Agreement States should have compatible or more restrictive regulations (10 CFR 37.57 is a Compatibility Category C).

The Agreement State shall determine if their licensee reported to the Local Law Enforcement Agency. If the licensee did not report the quantity of concern, the Agreement State shall determine if the radioactive materials ex ceeds the threshold for quantities off concern. If the reporting threshold was met, the Agreement State shall report to law enforcement and the NRC. If their licensee alread y engaged law enforcement, then the Agreement States shall report only to the NRC. See Appendix A for more specific instructions. If it is not clear whether an e vent should be categorized as a possible theft or terrorist activity, the Agreement State sho uld contact the HOC for assistance in determining if the event is required to be report ed.

Agreement States should consider notifying their local law enfo rcement and/or the U.S.

Federal Bureau of Investigation (FBI) in all cases of actual th eft, sabotage, diversions, and possible terrorism of radioactive material, regardless of t he quantity of radioactive material involved. Additionally, they should coordinate their c ommunications with other local, Federal and State Agencies (including the HOC) to ensure that shared information is accurate and consistent. The Agreement State should consider issuance of a press release, based on the H&S significance of the event.

The U.S. Code assigns lead responsibility for material events i nvolving theft or terrorist activities to the FBI. The All-Agreement State Letter SP-98-038, dated May 5, 1998, addressed the revision to the U.S. Code regarding the expansion of the FBI criminal investigative jurisdiction to include byproduct material.

5 NUCLEAR MATERIALS EVENTS DATABASE

NMED is a database that contains a historical collection of inf ormation on the occurrence, description, and resolution of events involving the use of nuclear material in the United States. The data includes information on material ev ents from January 1990 Handbook for Nuclear Material Event Reporting for the Page: 8 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

through the present.

Agreement States should email the NRC NMED Project Manager at NMEDNRC@nrc.gov to gain access. A ccess to NMED is only provided to the NRC, Agreement States, other federal government agencies, and/or fed eral government contractors who have the need to use the information in NMED. N MED is not publicly available.

The NMED website is at https://n med.inl.gov/Home/frmLogin. Approved users may download the software or use the web-based interface.

Section 3.4, Written Reports, provides information on how to submit written reports.

The following sections provides information on how to manage in formation within NMED.

5.1 Events Entered into NMED

Agreement States shall report events to the NRC in the manner t hat is described in Appendix A. The icons in Appendix A indicate whether the report ing requirement specifies a report to the HOC or a written report.

An NMED record is created after events are reported to the HOC. The NMED contractor uses the event information, as reported to the HOC, to establis h a record in the NMED database. The Agreement States Event Report Identification Num ber is included in the Reference field of the NMED record. This ensures that any sub sequent updates are correctly associated with the initial event record.

Agreement States can submit written reports to NMED electronica lly (email or upload) and via mail. These reports are entered into NMED by the Agreem ent State but they are not shared with the HOC. The HOC staff does not review written reports.

5.2 Retracted Events

The Agreement State may retract an event if it does not meet th e threshold of the reporting regulation. A retracted event will be marked as "not reportable" in NMED, which excludes it from most searches. The NMED record will rema in. The NRC will not request an Agreement State to retract an event.

5.3 Records Completed in NMED

An NMED record is complete when the event information recorded within NMED meets the minimum set of information criteria established in Appendix C, Minimum Required Event Information. This information may also be found on the N MED website under Help. After the NMED contractor reviewed the event informatio n and determined that it included the minimum set of information required for a complete event, the NMED contractor marks the NMED record as complete. In certain circum stances, some NMED records are unable to ever be marked as complete.

5.4 Records Closed in NMED

A complete record remains open in NMED until the Agreement Stat e has indicated the Handbook for Nuclear Material Event Reporting for the Page: 9 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

NMED record should be closed. Agreement States shall notify the NMED contractor when the NMED record can be officially closed (i.e., no further follow-up planned and/or no additional information expected). The regulatory agency shou ld ensure that the NMED record contains all pertinent technical information, inclu ding follow-up information, before requesting the event be closed via email or by including it in their event report update. An NMED record can be closed but not complete when no f urther action is planned.

Agreement States shall follow-up and review nuclear material ev ents through the closure of the event, which includes checking to see that the final rep ort information was entered into NMED. Search for NMED records that have been closed by the applicable regulatory agency under the field, Event Closed by Region/State.

5.5 NMED Annual Reports

An annual report presents the results of the statistical analys is of event data and any safety significant concerns. The NMED Annual Reports are availa ble to authorized NMED users in electronic form on the NMED website (https://nmed.inl.gov/) under Publications.

5.6 Voluntary Reports and Non-reportable Records

On April 1, 2019, NMED ceased capturing non-reportable events. Non-reportable records that were already in NMED will continue to be updated a s new information is received. Reports where the reportability is currently unknown will continue to be added to NMED as they may develop into reportable events when further information is received.

New non-reportable events are no longer entered into NMED. NMED only captures reportable events and events where the reportability is current ly unknown that may develop into reportable events when further information is rece ived. Situations that cannot be tied to any reporting r equirement (i.e., materials contaminated with radioactive material) are not tracked in NMED. Voluntary reporting to the H OC is still available as described in Section 3 of this Handbook.

5.6.1 Orphan Sources

For events where the owner of the radioactive source was not id entified, the keyword, Orphan Source, is added to the NMED record. Orphan sources with quantities of licensed material less than the 10 CFR Part 20 Appendix C, Quantities of Licensed Materials Requiring Labeling, are no longer tracked.

5.6.2 Found Source

A found source that is associated with a reporting requirement and a licensee is required to be reported in NMED. If the found source was not previously reported as lost, then it also needs to be reported. A found source with a quantity less than the reporting requirements (i.e., 10 CFR 20.2201, Reports of theft or loss o f material), can be voluntarily reported but it will not be tracked in NMED.

5.6.3 Landfill Radiation Monitor Alarms

Records of landfill radiation monitor alarms are added into NME D, unless the calculated/estimated activity of the lost nuclear material prov ided supports the determination that it is below the reportable threshold. A reco rd of the landfill radiation monitor alarms (with incomplete information) is marked as repor table or uncertain reportability in NMED, depending on the radionuclide and the NM ED Coding Manual.

If the radionuclide that sets off landfill radiation monitor al arms is not provided, the reportability will be listed as uncertain. If the Agreement Sta te assumes that a particular radionuclide was involved, that assumption will be listed in th e NMED record.

A landfill radiation monitor alarm with incomplete information is treated as non-reportable if the waste came from a residence.

6 GOVERNMENT COLLABORATION

6.1 Assistance from the NRC

Agreement States perform the event follow-up and investigation for events within their jurisdiction. For events with significant safety or security co ncerns, the Agreement State may request assistance from the NRC. The Agreement State should contact the HOC if activation of the NRC Incident Response Program is likely. If t he Agreement State needs assistance in assessing the scale and/or safety impact of an ev ent or assistance in calculating the dose, the Agreement State should contact their RSAO.

See NRC Inspection Manual Chapter (IMC) 1330, Response to Tran sportation Accidents Involving Radioactive Materials, and IMC 1360, Use of Physicians and Scientific Consultants in the Medical Consultant Program.

6.2 Radiological Emergency Response Assistance Available to the States

Agreement States may request radiological emergency response as sistance by contacting the HOC. The Federal government, upon request, has t he capability to assist States in responding to radiological emergencies. Under the Nuc lear Radiological Incident Annex to the Response and Recovery Federal Interagency Operational Plan, the NRC is the Lead Federal Agency (LFA) for domestic incident management for incidents involving radioactive materials or facilities license d by the NRC or Agreement States. As LFA, the NRC may request assistance from other feder al agencies (e.g.,

Department of Homeland Security, Federal Emergency Management A gency (FEMA),

Department of Energy, etc.)..

See IMC 1303, Requesting Emergency Acceptance of Radioactive M aterial by the U.S.

Department of Energy (DOE).

6.3 Congressional Inquiries

The NRC has the lead on responding to any inquiries from the U. S. Congress pertaining to events or other occurrences covered in this Handbook. The RS AO should contact the Agreement State to raise awareness of the inquiry and to obtain an answer ASAP, if Handbook for Nuclear Material Event Reporting for the Page: 11 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

appropriate. If the congressional inquiry is in depth, NMSS and /or Office of Congressional Affairs staff will issue a letter to the Agreemen t State and include a due date for the response.

7 EVENT NOTIFICATIONS

7.1 NRC Publication of Event Notifications

Events reported to the HOC are entered into an Event Notificati on (EN) database and are shared with select NRC staff. The ENs are publicly availabl e and published on the NRC public website (https://www.nrc.gov/reading-rm/doc-collecti ons/event-status/index.html). These ENs are added after a 5-business day hold. This hold includes the day of notification. For example, a report to the HOC made on a Wednesday is released on the following Wednesday. As a result of public acce ss to this information, Agreement States may be contacted by the public or media regard ing events.

ENs retracted during the 5-business day hold are not entered in to the EN database.

After events are published on the EN database, retracted events are removed.

7.2 Evaluation of Event Notifications

RSAOs review the ENs to ensure that they are abreast of the iss ues impacting the Agreement States. The RSAOs are responsible for serving as a po int of contact for NMSS staff and management, if any questions arise.

Select NMSS staff review all new and updated ENs. NMSS staff sh ould notify the appropriate RSAO if an event is reportable to the INES, a poten tial AO, or if an event indicates the possible presence of a generic issue.

ENs identified as having a significant potential risk to public health and safety, security, and/or the environment may receive additional NRC management re view.

7.3 Request for Additional Information

Additional information may be requested to help determine the s afety significance and any possible generic implications (e.g., equipment malfunction or failure, significant exposures). For significant events (i.e., immediate or 24-hour reportable events) such requests, normally initiated by the RSAO or NRCs Operation Cen ter staff, would occur on an as needed basis, possibly within hours to a few days of n otification of the occurrence.

For events not considered to be significant (i.e., not required to be reported within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ), the standard procedure is to allow at least 30 days bef ore making such requests to provide reasonable time for Agreement State review and evalu ation, and submission of follow-up information.

NMED sends a request for follow-up information via email when t he NMED record is incomplete after 60 days from the date reported to the regulato ry agency.

8 INTERNATIONAL NUCLEAR EVENT SCALE (INES) REPORTING

The IAEA maintains a scale used fo r rating the safety significance of events associated with the use of nuclear materials. Since 2004, the NRC has used the INES and shared event information with the international community for nuclear, transportation and radiation source events. INES events involve events occurring i n areas regulated by the NRC or the Agreement States.

The NRC does not require the States to classify events or to pr ovide direct notifications to IAEA using the INES scale. The NRC will use information prov ided by the States during their initial reporting and updates of the event for cla ssifying the event and notifying IAEA. The NRC has committed to notifying the IAEA of any applicable event that is rated at an INES Level 2 or higher within two business days.

For events that occur in an Agreement State, the RSAO provides the Agreement State with the draft INES Event Rating Form within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of its ge neration. The Agreement States are asked to concur that the information in the report i s factual. If the State cannot review the draft INES Event Rating Form in time to meet the two business days reporting deadline, the NRC provides the report to INES and mark the even t as Provisional.

A Provisional rating is also recommended in situations where not all the details of the event are known. The rating is issued based on the information that is available and the judgement of those understanding the nature of the event. If a Provisional rating is issued, a final rating needs to be issued with any differences explained.

For further information on INES reporting procedures and rating criteria, see MD 5.12, International Nuclear Event Scale Participation.

9 ABNORMAL OCCURRENCE

As previously discussed in Sec tion 2 Background, the NRC is responsible for determining if events reported by Agreement States meet the cri teria of an AO. NMSS performs an initial screening of all-Agreement State events aga inst the AO criteria in accordance with MD 8.1, AO Reporting. The RSAO contacts the A greement State if a potential AO is identified. The Agreement States shall support the NRC by providing information to the NRC on potential AOs that have occurred in t heir State.

The RSAO provides the Agreement State with a draft AO write-up. The Agreement State staff shall review the draft AO write-ups to verify that the de tails are correct and provide corrections to their assigned RSAO.

The NRC annually publishes NUREG-0090, Report to Congress on A bnormal Occurrences. It is publicly available and can be accessed at http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr00 90/.

The AO Report to Congress is also used to provide information o n significant materials issues and on adverse licensee performance. In accordance with SECY-02-216, Proposed Process for Providing Information on Significant Nucl ear Materials Issues and Adverse License Performance and SECY-11-0132, Revision of the Criteria for Identifying Nuclear Materials Licensees for Discussion at the A gency Action Review Handbook for Nuclear Material Event Reporting for the Page: 13 of 16 Agreement States, Interim Procedure SA-300 Issue Date:

11/28/2022

Meeting, Agreement State licensees will be considered, along w ith NRC nuclear material licensees, for discussion during the Annual Agency Act ion Review Meeting (AARM). The target audience for the AARM is the NRC Commission and it is open to the public.

NRCs MD and Handbook 8.14, Agency Action Review Meeting, des cribes NMSSs and the Regions participation. The NRC has the lead for the di scussion on Agreement State licensees, as necessary.

10 ASSESSMENT OF OPERATING EXPERIENCE

The NRC identifies events that may involve generic applicabilit y10 or could have significant impact on public heal th and safety, security, and/or the environment. The NRC issues Generic Communications 11 in response to identified trends, safety significant issues, or concerns with generic applicability.

The NRC assessment of events identify deficiencies and ensure t hat corrective actions are taken to prevent recurrence. The assessment may result in t he identification of actions that could lead to improvements in the effectiveness of the NRC and Agreement State regulatory programs.

The NRC evaluates issues using the criteria listed in MD 6.4, Generic Issues, to formally identify and process generic issues.

11 AGREEMENT STATE REVIEW OF NUCLEAR MATERIAL EVENTS FOR SAFETY SIGNIFICANCE AND GENERIC ASSESSMENT

Agreement States should assess events occurring within their ju risdiction or related to products registered or licensed in their jurisdiction to identi fy any events that may involve generic applicability12 or could have significant impact on public health and safety, security, and/or the environment. In the instance that the Agre ement State identified events with generic applicability and formalized it in an opera ting experience assessment or trending study, the Agreement State may submit th e assessment to the NRC to facilitate distribution. The NRC can post assessments to the NMED website and could also distribute in a letter to all-Agreement States. Emai l NMEDNRC@nrc.gov to initiate distribution.

Agreement States may process generic issues under their jurisdi ction through State processes or may request NRC assistance. The NRC evaluates issu es using the criteria listed in MD 6.4, Generic Issues, to formally identify and pr ocess generic issues.

10 An event may have generic applicability if the condition could impact other licensees of the same type or is part of an ongoing safety concern with one or more licensees. The concern should be evaluated for safety significance and resolved, if appropriate. The concern should be managed within the generic issue program if it meets the generic issue criteria.

11 Generic Communications are NRC documents to communicate with industry and the public regarding specific issues of generic nature. See the NRC public website, Generic Communications at:

https://www.nrc.gov/reading-rm/doc-collections/gen-comm/index.html.

12 See footnote 10 for a description of generic applicability.
