Safety assessment (storage of disused

sealed radioactive sources, Rakoviča)



Preliminary SAR for storage of DSRS (1)

1. Introduction

2. Regulatory arrangements

3. Safety assessment methodology

4. Areas of the storage facility

5. Safety assessment (main hazards identified in each of the areas) Source collection and transport to the storage facility Source receipt at the storage facility Source unpacking Temporary storage of a source Interim storage of conditioned sources




6. External events Man-made external events

Aircraft crash Missile impacts Transport accidents

Naturally occurring external events Seismic events Extreme environmental effects Meteorite impact Loss of services




7. Risk to operator exposure to direct radiation

(following dropping of a source)

input: estimated likelihood of incident, dose rate, time of exposure

8. Risks to members of the public (aircraft crash + fire)

input: nuclide inventory, release fraction, distance to source, weather category,

dose calculations for various exposure pathways

9. Conclusions



Licence application (Belgium)



Licence application in Belgium (1)The licence application for a waste management facility shall include:

1. identity of the applicant, the operator and the facility manager

2. the nature and purpose of the facility, the type and properties of the radiation and the radioactive substances, the destination of the equipment or substances, the location, the protection and safety measures (health physics control, medical surveillance of workers, optimisation of protection)

3. qualification and competence of staff

4. the number of staff members to be employed in the various sectors

5. the commitment to take out an insurance policy covering civil liabilities

6. the commitment to register with ONDRAF/NIRAS and to conclude an agreement with this agency for the management of all radioactive waste

7. a land registry plan and a topographical survey of the region located within a radius of 500 m around the facility and information on the population density within this perimeter and an ordnance survey map on a scale of 1/10,000 covering the 5 km radius around the facility



Licence application in Belgium (2)8. a preliminary safety report covering the following elements:

• geographical and topographical data about the site (geology, seismology, hydrology, meteorology, climatology, economic activities, including agriculture, traffic routes, and demographics)

• brief description of the installations

• safety principles to be applied for the construction and subsequent operation of the installations, including design basis accidents of internal or external origin and combinations of the latter

• selection of construction rules for equipment and civil engineering works

• brief description of the main circuits (fluid circuits, electrical circuits) and the instrumentation and control system

• anticipated qualifications for mechanical and electrical equipment



Licence application in Belgium (3)8. (cont’d)

• probabilistic safety analyses already available (for nuclear power plants and reprocessing facilities)

• anticipated radioactive discharges under normal operation and accident conditions and the anticipated operational limits

• quality assurance principles

• expected quantities of radioactive waste produced, including waste from decommissioning, treatment and temporary storage of this waste prior to disposal or handover to ONDRAF/NIRAS

9. a report on the study of the environmental impact of the proposed facility, i.e. a scientific study describing all direct and indirect effects in the short, medium and long term of the project on the environment
