2. Management system information

The CNSC expects licensees to adhere to all CSA N286-12 [1] principles as the basis of their management system. A management system implemented in accordance with these principles and requirements has features to assure safe operations. The requirements for a management system apply throughout the lifecycle of the licensed activity and extend to all safety and control areas (SCAs).

For nuclear facilities that do not have a licence condition for management system, the principles in CSA N286-12 can serve as guidance for establishing an effective management system. Further guidance on this matter is also found in other industry standards such as CAN/CSA-ISO 9001:16, Quality Management Systems – Requirements [2] and ISO 14001, Environmental management systems [3].

CSA N286-12 structure and principles

CSA N286-12 [1] integrates requirements from other management system standards for quality, health and safety, environment, economics and security. It therefore provides a basis upon which a single management system may be implemented.

CSA N286-12 is based on a set of 12 principles described below. The first two principles are aimed at ensuring that safety is properly considered in all decisions and actions, and that licensees are expected to define, plan and control their activities in order to meet all requirements:

  • safety is the paramount consideration guiding decisions and actions
  • the business is defined, planned and controlled

As captured in the next three principles, to meet all requirements an organization must ensure that it is aligned with top management direction and able to establish, communicate and achieve the objectives and priorities it sets for itself:

  • the organization is defined and understood
  • resources are managed
  • communication is effective

The remaining principles ensure that processes are established for managing activities consistently and for verifying that the desired objectives are achieved. Adherence to the following remaining principles can ensure that measures are in place to address deficiencies and to provide for continual improvement:

  • information is managed
  • work is managed
  • problems are identified and resolved
  • changes are controlled
  • assessments are performed
  • experience is sought, shared and used
  • the management system is continually improved

CSA N286-12 is organized for ease of use for applicable facility types mentioned in the standard. The standard shows the generic requirements applicable to the facility types listed below, while each section thereafter applies to one or a group of facilities identified in the title. The table below shows the various facility types and corresponding sections containing CNSC management system requirements.

This background information can help the user clarify the context of CSA N286-12 requirements. Also, CSA N286.0.1-14 refers to research materials that were used during the formulation of some of the requirements in CSA N286-12. The clause headings and numbers used in CSA N286.0.1-14 correspond to those in CSA N286-12.

3. Specific regulatory topics

3.1 Leadership

The role and behavior of leaders in an organization are fundamental to achieving excellence in safety. Through the development and implementation of an effective management system, the organization can better understand and promote a healthy safety culture.

CSA N286-12 [1] recognizes leadership in its scope and through requirements specific to top management. CSA N286-12 applies to top management, as defined in the standard, with overall accountability for the nuclear facility. Top management defines, plans and controls the business (licensed activities) through processes that define expectations for the organization and the means to monitor performance. Top management makes use of effectiveness reviews to continuously assess and improve its management system, as well as utilizing the latter to understand and promote a healthy safety culture.

In addition to CSA N286-12, recently issued management system standards, such as CAN/CSA-ISO 9001:16, Quality Management Systems – Requirements [2], and the IAEA’s GSR Part 2, Leadership and Management for Safety: General Safety Requirements [5], have further elaborated on the key role leaders have in an organization. For example, these standards include demonstrating leadership and commitment to the management system by:

  • taking accountability for the effectiveness of the management system
  • ensuring the integration of the management system requirements into the organization’s processes
  • communicating the importance of effective management and of conforming to the management system requirements
  • ensuring that the management system achieves its intended results
  • engaging, directing and supporting persons in order to contribute to the effectiveness of the management system
  • supporting other relevant management roles to demonstrate their leadership as it applies to their areas of responsibility
  • establishing, advocating and adhering to an organizational approach to safety that stipulates that issues relating to protection and safety receive the attention warranted by their significance
  • acknowledging that safety encompasses interactions between people, technology and the organization
  • establishing behavioral expectations and fostering a healthy safety culture
  • establishing the acceptance of personal accountability in relation to safety on the part of all individuals in the organization and ensuring that decisions made at all levels take account of the priorities and accountabilities for safety

3.2 Safety culture

An organization that actively fosters a healthy safety culture can have a powerful influence on employee attitudes and behaviours, and consequently, on individual and corporate safety performance.

The CSA N286-12 [1] safety culture requirement states the following: "Management shall use the management system to understand and promote a safety culture..."Footnote 2 It is through the management system that organizations understand their prevailing culture. Top management communicates the vision and objectives of the organization while upholding the key principle that "safety is the paramount consideration guiding decisions and actions". Safety culture is understood and improved through key management processes such as assessments and continuous improvement.

For further information on the CNSC’s approach to safety culture, refer to REGDOC-2.1.2, Safety Culture [6], which sets out specific requirements and guidance for assessing and fostering a healthy safety culture.

3.3 Supply chain

The specific requirements for a supply chain described in CSA N286-12 [1] apply to the supply of services as well as items. Licensees’ supply chain management processes implemented in accordance with CSA N286-12 are sufficiently robust to provide assurance that non-compliant items and services entering the supply chain are properly identified and dispositioned.

In addition to CSA N286-12, documents have been created by industry to lay out the management system requirements for suppliers. Some of these are contained in international, regional or national standards, such as CSA N299, Quality assurance program requirements for the supply of items and services for nuclear power plants [7], while others are created through industry support groups. These requirements are passed down by the licensee through contracts.

3.3.1 Counterfeit, fraudulent and suspect items

While not mentioned in any specific section of CSA N286-12 [1], effectively implemented supply chain processes and adherence to the requirements of the management system can mitigate against the introduction of counterfeit, fraudulent and suspect items (CFSI) into the supply chain of a nuclear facility and/or activity.

The global supply chain is often long and complex, and the source of CFSI may be unknown. The risks presented by CFSI can be reduced by the effective implementation of a management system in accordance with CSA N286-12.

It is important to note that it is not only the supply chain that is affected by CFSI. Organizational functions such as engineering, maintenance and operations also need to be cognizant of CFSI issues and able to deal with them.

Additional CFSI information is available in IAEA TECDOC-1169, anaging suspect and counterfeit items in the nuclear industry [8]. The Electric Power Research Institute’s (EPRI) report 1019163, Plant Support Engineering: Counterfeit and Fraudulent Items – Mitigating the Increasing Risk [9], provides information for the prevention, detection and mitigation of CFSI.

3.3.2 Management of contractors

The nuclear industry has recently increased the practice of engaging the services of contractors for a wide array of work, which includes not only the provision of lifecycle activities or specific one-time jobs, but also the conduct of routine processes such as maintenance. Therefore, licensees provide the oversight required to ensure the work performed by contractors meets regulatory requirements for which they are responsible. A management system aligned with CSA N286-12 provides the necessary processes and practices to ensure this.

3.4 Configuration management

Adherence to a management system that meets the requirements of CSA N286-12 [1] will ensure that the configuration of a facility is maintained. However, there has been a recognized need for standardized processes and guidance to enhance the understanding of configuration management at high-energy reactor facilities. As a result, CSA standard N286.10-16, Configuration management for high energy reactor facilities [10], was issued to provide guidance on maintaining configuration throughout the full lifecycle of a facility.

CSA N286.10-16 provides information that may also be used by other nuclear facility licensees for maintenance and management of facility configuration.

3.5 Software quality assurance

CSA standard N286.7-16, Quality assurance of analytical, scientific, and design computer programs [11], applies to high energy reactor facilities as defined in CSA N286-12. The standard sets out the quality assurance requirements for software used in design, safety analysis, and supporting activities. CSA N286.7-16 provides guidance for other classes of licensees who use software programs for the purposes mentioned above, as well as for other operational needs.

4. Radiation safety oversight: Nuclear substance licensees, radiation device licensees and Class II nuclear facility licensees

Nuclear substance licensees, radiation device licensees, Class II nuclear facility licensees, as with all holders of licences from the CNSC, have the primary responsibility for safety of the licensed activities. Licensees are expected to demonstrate that they are qualified to undertake the proposed activities and have made adequate provision for the health and safety of persons and protection of the environment. This includes demonstrating that they can manage and control the licensed activities. Licensees must provide effective management support, including both human and financial resources, to properly implement and maintain their radiation safety programs, meeting all of the programs’ regulatory obligations. This includes addressing the requirements of section 4 of the Radiation Protection Regulations.

When implementing safety and control measures, licensees should take into account the management system principles outlined in section 2 of this regulatory document, recognizing that measures should be appropriate to their unique structure and governance framework. Program oversight should be comprehensive and integrate the roles and responsibilities of the applicant authority, the radiation safety officer and the radiation safety committees, as applicable. Oversight activities include assessing the effectiveness of the safety and control measures, identifying opportunities for improvement and resolving any problems.

Licensees may have an existing system of controls and processes that govern their overall operations. In such cases, radiation safety programs should be integrated within the licensees’ existing management system.

The elements of leadership outlined in section 3.1 of this regulatory document should be employed by licensees’ top management. Furthermore, the principles underpinning a healthy safety culture, as described in section 3.2 of this document, should be considered by licensees when implementing their safety and control measures.
