ZED-2 Experiential Learning

Instructor: Luke Yaraskavitch, Julian Atfield
Experience Reactor Physics in action at CNL's ZED-2 zero-power research reactor. This one-day experiential course provides participants with a unique opportunity to observe and explore fundamental reactor behaviours, including criticality and dynamic response, in a controlled environment. Through pragmatic lectures and guided, interactive demonstrations like an approach-to-critical, learners will gain practical insight into how experimental reactor physics supports reactor design, safety analysis, licensing, and the validation of modern modelling and simulation tools used throughout the nuclear industry.

Course Description

This course provides exposure to experimental reactor physics using the ZED 2 zero power research reactor. Participants explore how key reactor physics observables, such as critical size, neutron flux, and kinetics characteristics, are measured in a reconfigurable test reactor.

A morning set of lectures explain the rationale for a zero-power test reactor and the types of experiments that are conducted here. Together with an afternoon demonstration and guided activities at the ZED-2 reactor, such as an approach-to-critical, learners gain practical insight into how experimental data that supports reactor design, safety analysis, and validation of simulation tools used in modern nuclear systems is produced. Further, how experimental reactor physics competencies are used in reactor commissioning will also be covered.

Learning Outcomes / Objectives

  • Understand the role of experimental data in reactor safety, design, and licensing, including the validation of modelling and simulation tools.
  • Understand the role of a zero-power reactor and how it is distinct from a materials test reactor
  • Describe fundamental experimental reactor physics concepts
    Recognize key experimental techniques used in reactor physics research and commissioning of reactors

Target Audience

This course would be most beneficial for nuclear engineers, reactor physicists, safety analysts, reactor operations personnel, researchers, regulators, and students seeking practical exposure to experimental reactor physics. It is particularly valuable for individuals involved in reactor design, safety analysis, commissioning, licensing, modelling and simulation, and nuclear technology development.

Certificate Information

Participants who successfully complete the course will receive a certification of completion issued by the CNLC.
