RegulatorySystems

Health

• Protection of workers

• ICRP• National regulations• Existing practices

• What about abnormal working situations? (Andreyeva)

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?

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?

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

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

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/ERA of sources in question

• Uncertainties in EIA and ERA should be communicated and understood
