Appendix C: Review Objectives for an Application for a Licence to Construct a Reactor Facility

When establishing the scope of the review for an application to construct a reactor facility, CNSC staff consider three levels of objectives. These objectives are developed to assist in integrating individual reviews into an overall assessment of the adequacy of a licence application.

C.1          First-level objectives

The first-level objectives are described in subsection 24(4) of the Nuclear Safety and Control Act (NSCA). Additionally, the facility design and operation needs to address the mitigation measures identified in the environmental review.

C.2          Second-level objectives

The second-level objectives are:

S           Design safety objective: The design of a reactor facility to be constructed should make adequate provisions (not pose an unreasonable risk) for the protection of the environment, the health and safety of persons and the maintenance of national security and measures required to implement international obligations to which Canada has agreed.

C           Construction program objective: Adequate provisions should be made for the construction of the reactor facility to be carried on in a safe manner and with sufficient quality.

Q           Qualifications objective: The applicant, and all entities involved in the design, construction and commissioning of the reactor facility, should be qualified to carry on the licensed activity. The program and schedule for recruiting, training, qualifying and certifying workers in respect of the operation and maintenance of the reactor facility should be adequate.

The design safety objective captures a large portion of the general nuclear safety objective, as established by the International Atomic Energy Agency (IAEA) and explicitly stated in REGDOC‑2.5.2, Design of Reactor Facilities: Nuclear Power Plants [9] that reactor facilities “be designed and operated in a manner that will protect individuals and society from harm”.

The construction program objective expresses the high-level expectations for the construction program.

The qualifications objective expresses the high-level expectations to have adequately qualified persons for the design, construction and commissioning of the reactor facility. It also addresses the requirements of the Class I Nuclear Facilities Regulations related to training, qualification and certification of workers.

C.3          Third-level objectives

In essence, meeting the design safety objective means satisfying the relevant expectations outlined in:

·       REGDOC‑2.5.2, Design of Reactor Facilities: Nuclear Power Plants [9]

·       REGDOC‑2.4.1, Deterministic Safety Analysis [24]

·       REGDOC‑1.1.1, Site Evaluation and Site Preparation for New Reactor Facilities [26]

At an intermediate level, the expectations of REGDOC‑2.5.2 [9] may be grouped in several main categories, which can be thought of as the third-level objectives for a CNSC staff review of an application for a licence to construct a reactor facility.

Third-level objectives related to the design safety objective are:

SO1      The design captures all of the mitigation measures identified during the environmental review and ensures that operating performance meets all regulatory requirements concerning the nuclear and hazardous releases.

SO2      The design follows the ALARA principle.

SO3      The design complies with the dose acceptance criteria and safety goals.

SO4      The design complies with the defence-in-depth principle.

SO5      The fundamental safety functions perform adequately in the design.

SO6      The design provides adequate means to mitigate and manage accidents.

SO7      Adequate design provisions have been made for security and design robustness.

SO8      The management system of programs, policies and procedures fosters a healthy safety culture and it is adequate for the design, construction, and commissioning of the reactor facility.

SO9      The management system of programs, policies and procedures fosters a healthy safety culture and it is adequate for the future operation and decommissioning of the reactor facility.

SO10    Adequate design, infrastructure and programmatic provisions are made in the area of safeguards.

Third-level objectives related to the construction program objective are:

CO1     Adequate assurance that all activities involving construction/erection of structures and systems and fabrication/erection of components are carried out by qualified personnel.

CO2     Adequate provisions have been made to ensure that relevant rules and regulations will be followed during fabrication, construction and erection activities and that the construction/erection activities are conducted in a safe manner.

CO3     Sufficient quality of fabrication, erection and construction is assured and adequate provisions are made to minimize design deviations.

CO4     Adequate plans for inactive commissioning of the built reactor facility (without a fuel load) are in place.

Third-level objectives for the qualifications objective are:

QO1     The applicant is qualified to oversee all design, construction and commissioning activities carried out by itself, or by contractors or subcontractors.

QO2     The applicant has enough qualified staff to oversee all design, construction and commissioning activities carried out by itself, or by contractors or subcontractors.

QO3     All contractors and subcontractors involved in the design, construction and commissioning of the reactor facility are qualified to carry out their respective activities.

QO4     The proposed full-scope training simulator for the reactor facility is adequate.
