Purpose license revision

• New desired situation compared to licensed situation due to:

– extension HLW treatment & storage building (HABOG +)

• life extension NPP (Borssele)

– Extension DUO storage building (VOG2)

• continuing enrichment of Uranium-235 (Urenco)

Environment Impact Assessment (EIA)

• Insight expansion plans

• Effects to environment

– Radiological (SR)

– Non-radiological

• Stakeholders participation

• Underpinning arguments

– positive decisions of requested HABOG+ & VOG2

Policy and assessment framework

25

Aspects in Safety assessment

The fundamental element of the safety assessment is the assessment of the radiological impact on humans and the environment in terms of both radiation dose and radiation risks

Safety Assessment Report (SAR)

• shall include:

– Testing of initial ideas for safety concepts;

– Site or location selection;

– Demonstration of the safety of the facility;

– Optimization of the facility design;

– Evaluation of clearance and discharge;

– Safety Impact Assessment;

• operational maximum inventory of waste

– Definition of operational limits & controls;

Cie EIA

• On 30/12/2014 the Commission (Cie EIA) considered that the EIA contains the essential information to take a decision about the revision of the license in which the environment is taken full into account!

43

LICENSE !

• On 7th of January 2015: I (the Minister) have found that the implementation of the proposed changes to the décor is justified and that the planned expansion of the HABOG+ and VOG2 is to be built in a responsible and safe manner !

• However: final decision is by State Council on 8th of September 2015
