Enhancing Regulatory Systems for Environment, Health, and Safety: Recommendations for Effective Risk Reduction

This article provides recommendations for improving regulatory systems related to environment, health, and safety, emphasizing the need for risk assessments and prioritizing risk reduction measures. Suggestions include performing Environmental Impact Assessments (EIA) and Environmental Risk Assessments (ERA) before making decisions on countermeasures and nuclear sources, developing common approaches for EIA/ERA, and communicating uncertainties effectively.

  1. Health RegulatorySystems Environment Safety

  2. Health • Protection of workers • ICRP • National regulations • Existing practices • What about abnormal working situations? (Andreyeva)

  3. Environment • International conventions • Espoo convention • Waste convention etc. • National regulations related to discharges and waste management • What about discharges during remediation of contaminated areas? (Andreyeva) • Specifications for management of radioactive waste • Criteria for long term safety of facilities?

  4. Safety • Risk assessments to prioritise risk reduction measures • Safety convention • Hazard identification, safety analysis, safety assessment and emergency preparedness • How to find the balance between need for actions and risk associated with the actions?

  5. Regulatory systems • Prime responsibility with operator • Constructive dialogue with regulators • Responsibilities of different regulators • Clear who is lead regulator on a given issue • Cooperation between regulators • Regulations • Clear which apply when • Avoid gaps and overlaps • Holistic approach • Interactions between environment, health and safety

  6. Priorities Potential actions Environment, Health and Safety Assessents Risk characterisation Sources and sites

  7. Risk reduction Risk No action Regulatory levels Various actions Time

  8. ? Priorities of actions 1 ---- 2 ---- 3 ---- 4 ---- 5 ---- Regulatory systems !

  9. Recommendations • EIA and ERA should be performed prior to all decisions made with respect to countermeasures • EIA and ERA should be performed for situations without measures and with measures • EIA and ERA should be performed to select between alternative measures • EIA and ERA should be performed to prioritise sources of risk

  10. Recommendations • EIA/ERA should be performed for all nuclear sources prior to actions taken • Common approaches and methods for EIA/ERA should be developed • Uncertainty estimates in EIA and ERA should be included in the assessments • Joint effort (fieldwork etc.) should be undertaken to reduce the uncertainties in EIA/ERAof sources in question • Uncertainties in EIA and ERA should be communicated and understood
