Nuclear Safety Training

Lesson 1 • Nuclear Safety Culture Principles

Defines safety culture attributes including leadership commitment and questioning attitude. Links organisational behaviour to accident prevention outcomes.

Lesson 2 • Regulatory Framework Overview

Introduces the hierarchy of nuclear safety regulations, licensing, and oversight bodies. Establishes compliance expectations that govern all facility operations.

Lesson 3 • Basics of Nuclear Physics

Covers atomic structure, radioactive decay, and fission reactions. Provides the physical basis for understanding radiation hazards throughout the course.

Lesson 1 • Radiation Monitoring Fundamentals

Introduces personal dosimeters, area monitors, and contamination survey instruments. Establishes monitoring as the primary tool for verifying exposure control.

Lesson 2 • Occupational Exposure Limits

Presents dose limits for workers, the public, and special populations such as pregnant workers. Grounds limit-setting in the ALARA principle and risk-based rationale.

Lesson 3 • Radiation Dose Quantities and Units

Defines absorbed dose, equivalent dose, and effective dose with their measurement units. Provides the quantitative language used in all exposure assessments.

Lesson 1 • Radiological Work Permits

Explains the permit system for authorising work in radiological areas, including hazard surveys and controls. Links permit requirements to regulatory compliance.

Lesson 2 • Contamination Control Practices

Defines contamination zones, control boundaries, and housekeeping standards. Prevents spread of radioactive material within and beyond the facility.

Lesson 3 • Personal Protective Equipment

Covers selection, donning, doffing, and limitations of PPE for radiological environments. Prevents internal contamination and skin dose during hands-on tasks.

Lesson 4 • Internal Dose and Intake Control

Addresses inhalation, ingestion, and wound pathways for internal contamination. Establishes bioassay and air monitoring as intake verification tools.

Lesson 1 • Human Error Theory and Taxonomy

Explains skill-based, rule-based, and knowledge-based errors and their organisational precursors. Provides a shared language for analysing and preventing human failures.

Lesson 2 • Event and Near-Miss Reporting

Establishes a non-punitive reporting culture and the process for documenting and trending events. Converts near-misses into organisational learning opportunities.

Lesson 3 • Root Cause Analysis Methods

Applies apparent cause evaluation and root cause analysis to significant events. Produces corrective actions that address systemic causes rather than symptoms.

Lesson 4 • Procedure Adherence and Rigor

Reinforces place-keeping, concurrent verification, and flagging of procedure conflicts. Prevents procedure-related errors that are a leading cause of nuclear events.

Lesson 1 • Normal Operating Procedures

Introduces procedure hierarchy, use-and-adherence standards, and step verification. Establishes procedural compliance as a primary defence against operational errors.

Lesson 2 • Coolant and Heat Removal Systems

Explains primary and secondary coolant circuits, pumps, and heat exchangers. Highlights decay heat removal as a critical post-shutdown safety function.

Lesson 3 • Instrumentation and Control Systems

Covers reactor protection systems, interlocks, and control room instrumentation. Explains how automatic and manual controls maintain safe operating parameters.

Lesson 4 • Engineered Safety Features

Describes emergency core cooling, containment, and filtered ventilation systems. Demonstrates defence-in-depth through multiple independent safety barriers.

Lesson 1 • Criticality Accident Recognition and Response

Identifies criticality accident indicators and immediate evacuation and notification actions. Prepares personnel to respond correctly in the first minutes of an event.

Lesson 2 • Criticality Physics Fundamentals

Explains neutron multiplication, the criticality equation, and the role of moderators and reflectors. Provides the physical basis for all criticality control strategies.

Lesson 3 • Criticality Control Parameters

Covers mass, geometry, concentration, moderation, and reflection as the five key control parameters. Enables systematic hazard evaluation for fissile material operations.

Lesson 1 • Protective Actions for Personnel

Covers evacuation, shelter-in-place, accountability, and potassium iodide administration. Ensures personnel can execute protective actions quickly and correctly.

Lesson 2 • Emergency Classification System

Defines the four emergency action levels and the criteria for declaring each class. Enables timely and accurate classification to trigger appropriate response actions.

Lesson 3 • Emergency Dose Control

Establishes dose limits for emergency workers and authorisation procedures for exceeding normal limits. Balances life-saving actions against radiation risk.

Lesson 4 • Drills, Exercises, and After-Action Review

Explains the design, conduct, and evaluation of emergency drills and full-scale exercises. Drives continuous improvement through structured after-action findings.

Lesson 1 • Waste Minimisation and Segregation

Presents source reduction, reuse, and segregation strategies to reduce waste volume and activity. Lowers disposal costs and long-term radiological risk.

Lesson 2 • Radioactive Waste Classification

Defines low-level, intermediate-level, and high-level waste categories by activity and heat. Determines appropriate handling, packaging, and disposal pathways for each class.

Lesson 3 • Waste Packaging and Labelling

Covers container selection, radiation and contamination limits, and labelling requirements. Ensures safe handling and traceability from generation to disposal.
