REGDOC-3.1.2: Reporting Requirements for Non-Power Reactor Class I Nuclear Facilities and Uranium Mines and Mills

Preface

This regulatory document is part of the CNSC’s reporting requirements series of regulatory documents, which also covers reporting requirements for nuclear power plants and other nuclear facilities. The full list of regulatory document series is included at the end of this document and can also be found on the CNSC’s website.

Regulatory document REGDOC-3.1.2, Reporting Requirements for Non-Power Reactor Class I Nuclear Facilities and Uranium Mines and Mills sets out requirements and guidance for reports and notifications that licensees of Class I nuclear facilities (excluding power reactors) and of uranium mines and mills must submit to the CNSC. This document presents the types of reports, their frequency and the applicable timeframe for reporting.

This document replaces the following regulatory documents:

  • R-25, Preparation of a Quarterly Report on the Operation of a Uranium Refinery or Uranium Chemical Conversion Facility
  • R-26, Preparation of a Quarterly Health Physics Compliance Report for a Uranium Fuel Fabrication Plant
  • R-27, Preparation of an Annual Compliance Report for a Uranium Fuel Fabrication Plant
  • R-89, The Preparation of Reports of a Significant Event at a Uranium Processing or Uranium Handling Facility

REGDOC-3.1.2 is intended for inclusion in licences. This document will be used to assess new licence applications for nuclear facilities and activities.

Guidance contained in this document exists to inform the applicant, to elaborate further on requirements or to provide direction to licensees and applicants on how to meet requirements. It also provides more information about how CNSC staff evaluate specific problems or data during their review of licence applications.

Licensees are expected to review and consider guidance; should they choose not to follow it, they should explain how their chosen alternate approach meets regulatory requirements. An applicant or licensee may put forward a case to demonstrate that the intent of a requirement is addressed by other means and demonstrated with supportable evidence.

The requirements and guidance in this document are consistent with modern national and international practices addressing issues and elements that control and enhance nuclear safety. In particular, they establish a modern, risk-informed approach to reporting requirements.

Important note:

Where referenced in a licence either directly or indirectly (such as through licensee-referenced documents), this document is part of the licensing basis for a regulated facility or activity.

The licensing basis sets the boundary conditions for acceptable performance at a regulated facility or activity, and establishes the basis for the CNSC’s compliance program for that regulated facility or activity.

Where this document is part of the licensing basis, the word "shall" is used to express a requirement to be satisfied by the licensee or licence applicant. "Should" is used to express guidance or that which is advised. "May" is used to express an option or that which is advised or permissible within the limits of this regulatory document. "Can" is used to express possibility or capability.

Nothing contained in this document is to be construed as relieving any licensee from any other pertinent requirements. It is the licensee’s responsibility to identify and comply with all applicable regulations and licence conditions.

1. Introduction

1.1 Purpose

This regulatory document sets out requirements and guidance for reports and notifications that licensees of Class I nuclear facilities (excluding power reactors) and of uranium mines and mills must submit to the Canadian Nuclear Safety Commission (CNSC). This document presents the types of reports, the frequency and the applicable timeframe for reporting.

Licensees are required to report to the CNSC regarding situations, events and dangerous occurrences that may require short-term action by the CNSC. Licensees must also submit an annual compliance monitoring report.

Licensees are also required to provide notification of certain normal business activities (such as work disruptions or financial status) and to file specific records with the CNSC in accordance with the Nuclear Safety and Control Act (NSCA) and the regulations made under the NSCA.

2. Reporting Requirements

The following reporting requirements apply for Class I nuclear facilities (excluding power reactors) and uranium mines and mills:

  1. the licensee shall file a report to the Commission in response to:
    • a. an event or a situation, or
    • b. a dangerous occurrence as stipulated in section 35 of the PTNSR 2015
  2. as required, licensees shall provide other notifications or reports, including a failure to comply with section 26 of the PTNSR 2015
  3. all reports filed by the licensee according to this regulatory document shall contain the name and address of the sender of the report, and the date the report was submitted to the Commission
  4. after determining if a situation, event or dangerous occurrence is reportable, the licensee shall immediately notify, or file a preliminary report to, the Commission
  5. the licensee shall report on the specific reporting provisions and licence conditions listed in table A in appendix A of this document, such as:
    • a. the discovery of counterfeit, fraudulent or suspect items
    • b. reaching an action level for radiation protection
    • c. reaching an action level for environmental protection
  6. a full report, preliminary report or notification shall:
    • a. contain the specific information required by regulations; see sections 4.1 and 4.2
    • b. be submitted within the timeframes found in appendix A

Guidance

The NSCA and the regulations made under it state that reports are submitted to "the Commission”. In terms of submitting reports and notifications, "the Commission" is understood to be “the CNSC". The licensee should contact their CNSC licensing specialist to determine details for submitting any particular report.

Table A in appendix A provides a list of situations and events to be reported, regardless of their safety significance. This table also includes other types of notifications or situations that must be reported even though they do not meet the definition of an event.

In addition to the list above, the licensee may be required to file facility-specific reports, as described in their licence conditions handbook (LCH).

In item 4 in the list above, "immediately" means as soon as practicable after the licensee becomes aware that a situation or event is reportable (however, for a dangerous occurrence, after the obligations listed in subsection 36(1) of the PTNSR 2015 have been met); that is, after the licensee has taken steps to mitigate the consequences (as applicable).

A preliminary report or notification that must be submitted immediately may be provided in person, by telephone, by email or by fax. Full reports may be filed by email, by fax or by regular mail. All information (including supporting information such as data for air/water monitoring) may be submitted in electronic format (for example, a database).

For an emergency involving a nuclear facility or nuclear substances, the licensee should contact the CNSC Duty Officer emergency telephone number. An emergency includes:

  • any accident involving a nuclear reactor, nuclear fuel facility, or nuclear substances
  • lost or damaged nuclear substances
  • any threat, theft, smuggling, vandalism or terrorist activity involving a nuclear facility or nuclear substances
  • an unplanned spill or release
  • a worker injury that requires offsite medical response
  • any event that requires activation of a site emergency plan

Note: If an emergency is reported to the CNSC duty officer, a preliminary report or immediate notification is not required.

Licensees may develop facility-specific reporting schemes, provided they meet the reporting requirements set out in this document. A facility-specific reporting scheme allows site-specific situations to be described in greater detail than the examples provided in this document (which is intended to cover many facility types); thus clarifying reporting requirements and reducing uncertainty following an event. Licensees using this option are required to submit their facility-specific reporting scheme to the CNSC. The reporting scheme may be referenced in the CNSC’s LCH for that licensee.

The licensee should make all reasonable efforts to obtain timely information that has been reviewed for accuracy when filing a report to the CNSC. For reports of situations or events that have not attained stability and predictability, timeliness of informing CNSC staff of the situation or event should be prioritized over the availability of data and/or information.

A situation or event that triggers multiple reporting provisions may be amalgamated into a single report at the licensee’s discretion.

Licensees should use the reporting provisions of table A that best correspond to the reported situation(s) or event(s). If, after further investigation, the licensee concludes a situation or event was not reportable, the licensee may provide the CNSC with a written statement that includes a justification of their conclusion.

If the licensee determines that investigation beyond the preliminary report is unlikely to yield further relevant details or identify additional corrective actions to prevent recurrence of the situation or event, then a full report may not be necessary. In this case, the preliminary report should include the information required by the full report.

Licensees should use the situation or event reporting according to this regulatory document as an input to their public disclosure protocol.

Each report should be unclassified and should not contain any proprietary business information so it can be made available to the public upon request. Information should be considered public for the most part. Any information considered classified, protected, proprietary or personal should be submitted in accordance with the CNSC’s Guidance Document on Confidential Filings [1].

3. Annual Compliance Monitoring Report

The licensee shall submit an annual compliance monitoring report that includes:

  1. information that can be made available to the public (note: any classified, protected, proprietary or personal information shall be submitted to the CNSC separately in accordance with the CNSC’s Guidance Document on Confidential Filings [1])
  2. sufficient details to provide CNSC staff with information to verify that licensees are meeting their regulatory requirements and are operating safely
  3. information on each of the 14 areas in the CNSC’s safety and control area (SCA) framework and other matters of regulatory interest; if a particular SCA is not relevant or does not apply to the facility or to the activities of a facility, the licensee shall include a statement to that effect in the report

Each annual compliance monitoring report shall act as a stand-alone document. If information from any previous annual compliance monitoring report is needed for completeness, the licensee shall repeat it to the appropriate level of detail.

Guidance

For sites with multiple facilities (under the same licence) or a licensee possessing a licence with multiple locations, the licensee may submit a single consolidated annual compliance monitoring report.

The licensee may be required to submit additional compliance monitoring reports (e.g., quarterly, monthly or licensee-specific) as described in their licence or LCH. For example, other compliance monitoring reports may be required for new facilities or in situations where additional reporting is necessary (such as following a reportable event).

Flexibility is allowed for integrated/harmonized reporting. For example, if a licensee is required to submit reports to regulatory bodies other than the CNSC, then sending a copy of the report to the CNSC is acceptable provided the copied report contains all reporting information required by the CNSC. This option allows the licensee to avoid duplication of effort and to minimize administrative burden.

Appendix B provides a sample structure for an annual compliance monitoring report, based on the CNSC’s SCA framework. The licensee is under no obligation to follow this format; however, the report should include all of the information listed in appendix B, as applicable.

4. Specific Reports and Notifications

Table A in appendix A provides a list of the situations and events for which a report or notification is required, and includes the timing for each report or notification.

4.1 Contents of the preliminary reports and immediate notifications

A preliminary report or immediate notification of a situation or event, or of a dangerous occurrence as stipulated in section 35 of the PTNSR 2015, shall contain the following information:

  1. the location
  2. the circumstances, including:
    • a. a description
    • b. date and time of the onset and the duration, or date and time of discovery (if the time of occurrence is not known)
    • c. whether the situation, event or dangerous occurrence is ongoing or not
  3. a description of any actions the licensee has taken or proposes to take
  4. for situations and events, any preliminary information that is available regarding the effect on the health, safety and security of persons or the environment

Guidance

If the licensee has additional information on the situation or event, the licensee should include it in the preliminary report or notification. Preliminary reports should contain enough information that CNSC staff have an understanding of the effects of the event on the health, safety and security of Canadians and the environment.

4.2 Full reports

A full report shall contain the following information as far as practicable and applicable:

  1. reference to the original preliminary report or notification
  2. the date, time and location where the situation or event occurred or, if unknown, the approximate date, time and location and the date and time of becoming aware of the situation or event
  3. the probable cause of the situation or event
  4. a description of the situation or event and the circumstances including, if applicable, any problem with a radiation device
  5. the effects on:
    • a. the health, safety and security of persons or the environment
    • b. the maintenance of national security
    • c. if applicable, international obligations that have resulted or may result from the situation or event
  6. the effective dose and equivalent dose of radiation received by any person as a result of the situation or event, including the measured or estimated doses to the public
  7. if the situation or event involved an exposure device, the qualifications of the workers, including any trainees, who were involved
  8. if applicable, information on the nuclear substance and the name, model and serial number of the radiation device involved
  9. for dangerous occurrences (under PTNSR 2015), the names of persons involved and the details of the packaging and packages
  10. the actions that the licensee has taken or proposes to take, including actions identified and taken to re-establish normal operations and actions taken or proposed to prevent a recurrence
  11. any actions that the licensee has taken to inform the public and target audience about the situation or event

Guidance

Licensees should include information that allows the report to be reviewed efficiently; for example:

  • identify updates and new or additional information from that provided previously
  • identify any further missing information and the date that the missing information will be provided to the CNSC
  • identify the target completion date for each action that the licensee proposes to take to reestablish normal operations or to prevent a recurrence
  • provide a summary of any analysis completed, including the probable cause(s) and conclusions drawn from the investigation(s) after the situation or event
  • provide an evaluation of any deficiencies in design, operations, training, management or human performance uncovered by the situation or event

4.3 Action level reports

When a licensee becomes aware that a radiation protection action level or an environmental protection action level has been reached, the licensee shall:

  1. within the time period specified in the licence, notify the CNSC that an action level has been reached
  2. within 60 days of the notification date (or, if the licence specifies a different time period, within that time period), file a report with the CNSC that:
    • a. describes the results of the investigation conducted to establish the cause of reaching the action level
    • b. describes the steps identified and taken to restore the effectiveness of the radiation or environmental protection program
    • c. identifies any incomplete information and describes how and when the information will be provided to the CNSC

4.4 Specific reports under the Packaging and Transport of Nuclear Substances Regulations, 2015

Expert assessment of a dangerous occurrence in packaging and transport

As per subsection 36(2) of the PTNSR 2015, in the event of a dangerous occurrence in the packaging or transport of radioactive material or a nuclear substance, the consignor, carrier or consignee must have an expert in radiation protection assess the situation. The expert must report the results of the assessment to the Commission as soon as feasible.

Note: "As soon as feasible" means as soon as the licensee becomes aware that a dangerous occurrence is reportable but after the obligations listed in subsection 36(1) of the PTNSR 2015 have been met.

Annual report of radiation detections in packaging and transport

As per subsection 3(1) of the PTNSR 2015, any nuclear substance referred to in paragraph 2(2)(o) (of the PTNSR 2015) must be characterized at the earliest possible time to determine the extent to which it is subject to the PTNSR 2015 and the Nuclear Substances and Radiation Devices Regulations.

As per paragraph 3(3)(b) of the PTNSR 2015, the person who performs the characterization must file an annual report with the Commission by April 30 that contains a summary of radiation detections for the calendar year before the date of the report.

Appendix A: Reports, Notifications and Timing

Table A lists the situations and events that require a report or notification, along with timeframes for providing the report or notification:

  • for significant situations or events, the report is due immediately (where "immediately" means as soon as the licensee becomes aware that an event is reportable) and, if required, shall be updated with additional information in a full report within 60 days after becoming aware of the event
  • some exceptions on timing apply to specific situations and events; reports are due within 21 days for radiation devices and sealed sources, safeguards, packaging and transport, and for exposures in excess of legal radiation dose limits
