18 Questions
What is the ultimate responsibility of the applicant or licensee in relation to the design of a reactor facility?
To ensure the continuing safety of the plant design
Which of the following is NOT a factor considered in the design of a reactor facility?
Location in a populated area
What is an essential requirement for the reactor facility design according to the text?
Meeting Canadian regulatory requirements
Who is responsible for carrying out the design process of a reactor facility?
Appropriately trained staff at all levels
What is crucial for the management system to ensure throughout the lifetime of a reactor facility?
Continuing safety of the plant design
Which factor must be considered when designing a reactor facility, based on the text?
Current safety practices
What is the purpose of the DECs in the context provided?
To enhance the plant's capabilities to withstand severe accidents.
How should the design handle plant states that could lead to significant radioactive releases?
By ensuring that radioactive releases are practically eliminated.
What methods are recommended for the design of DECs?
A combination of phenomenological models, engineering judgment, and probabilistic methods.
What is the purpose of identifying a radiological and combustible gas accident source term in the design?
For use in specifying complementary design features for DECs.
What role do the rules and practices applied to complementary design features play?
They do not need to incorporate the same degree of conservatism as those applied to the design basis.
How do complementary design features help cope with DECs?
By providing additional safety measures beyond the design basis requirements.
Which category of plant states includes start-up, power operation, shutting down, shutdown, maintenance, testing, and refueling?
Normal operation
What are design extension conditions (DECs) in the context of reactor facility design?
Beyond-design-basis accidents considered during the design process.
In the context of reactor facility design, what is the primary goal regarding design extension conditions (DECs)?
To keep releases of radioactive material within acceptable limits.
Which term is used to describe a safety deviation from normal operation that may occur several times during the lifetime of a reactor facility without causing significant damage?
Anticipated operational occurrence (AOO)
What distinguishes between an anticipated operational occurrence (AOO) and a design-basis accident (DBA) in reactor facility design?
Severity of potential damage
Which term refers to a subset of beyond-design-basis accidents considered during the design process to ensure radioactive material releases remain acceptable?
Design extension conditions (DECs)
Test your knowledge on reactor safety design features, including characteristics of fissile and fissionable material, fuel design, moderator and coolant mass, safety management, and more.
