Radiation Safety Training for Workers at OPAL • Basic Radiation Safety Course 1 • Radiation Safety Workshop 2 • OPAL Radiation Safety Course 3 • OPAL Radiation Safety Refresher 4 3

Who is the training for? OPAL Refresher Basic Course Workshop OPAL Course • This course provides • This course provides • This course provides • This course provides experienced a basic introduction an introduction for workers with an workers with to Radiation Safety new workers and understanding of refresher training on at ANSTO for new refresher training the radiological the radiological workers for experienced hazards and the hazards and the workers in the radiation protection radiation protection Radiation Safety arrangements at the arrangements at the section of the OPAL facility OPAL facility ANSTO Work, • It is designed for: Health and Safety • It is designed for: OPAL Shift Managers, Management OPAL Shift Managers, Reactor Operators, System Reactor Operators, Utilisation staff, Utilisation staff, Maintenance staff, Maintenance staff, Health Physics Health Physics Surveyors/Radiation Surveyors/Radiation Protection Advisors Protection Advisors and all other and all other Nuclear Nuclear Operations Operations staff staff required to required to regularly regularly access access radiologically radiologically controlled areas in controlled areas in OPAL for work OPAL for work 4

Why is it required? OPAL Refresher Basic Course Workshop OPAL Course • To provide • To provide • To provide • To provide participants with a participants with participants with participants with a more detailed the knowledge and the knowledge and basic understanding understanding of the skills to work safely skills required to of the radiation radiation protection in radiologically work safely and protection arrangements and classified areas responsibly in arrangements and the radiological radiologically the radiological hazards at the OPAL classified areas and hazards at the OPAL facility to meet their facility responsibilities as workers enrolled on the ANSTO Dosimetry Service 5

Syllabus for the OPAL Refresher • Read 5 key OPAL Radiation • Dose Limits and Constraints Safety documents such as the • Radiological classifications in OPAL Documentation Pre-reading OPAL RP plan and Entry and • Access to Restricted and Forbidden Areas OPAL Radiation Safety online eLearn module Exit Requirements for • Safety Hazard Notice Boards Classified Areas at OPAL • Dosimetry Requirements for External/Internal exposures • Work Place and Area Monitoring • Self paced and the learner can • Portable Radiation Monitoring Instruments and Scenarios save were they are at, at any • Radiation Monitoring System time and then come back to where they left off • Maps of L-5 with pictures of components or systems and typical dose rates at Power and Shutdown • Maps of L-7 with pictures of components • Maps of L+13 with pictures of systems or components where it’s possible to get contamination from • What is tritium, where can it be found at OPAL and how can it get into your body • Airborne Contaminants at OPAL • Liquid Contaminants at OPAL • Self paced and the learner can save were they are at, at any time and then come back to where they left off 7

Learning Objectives for the OPAL Refresher • Describe the radiation protection program at OPAL • Describe the radiological hazards at OPAL and their origin/source • Describe the controls in place to minimise exposure to these radiological hazards • List the dosimetry requirements for each classification area and specific work scenarios • Describe the contamination controls in place at OPAL to prevent/minimise internal doses • Describe the radiation area monitors for dose rate and tritium contamination in air and how to obtain readings before entry to certain areas • Describe the ways tritiated water can enter the body, prevention & monitoring following an intake • Describe one common radioactive contaminant in OPAL pool water and the best way to prevent it getting on the skin 8

Example Content for the OPAL Refresher 9

Assessment for the OPAL Refresher Summative Assessment Pre-reading: Formative Assessment • Assessment 20 multiple choice • To gauge the participant’s questions with 60% required to pass understanding that DTO vapour with Online eLearn module: the more restrictive DAC poses a • Assessment 10 multiple choice greater potential hazard than Tritium questions with 80% required to pass gas at OPAL 10

Evaluation for OPAL Refresher • Prior to rollout - Extensive testing and evaluation by select ANSTO Radiation Protection personnel and OPAL staff. • Following pilot course - Verbal feedback was collected from learners. • Yearly review planned, with next version to have a mechanism for written feedback 11

Conclusion The successful application of the SAT process has lead to a radiation safety training program that meets the: • organisational safety goals and regulatory requirements. • needs of the staff at OPAL in terms of providing them with the knowledge, experience, skills and a questioning attitude to radiation safety. 12
