DECOMMISSIONING SAFETY REFERENCE LEVELS REPORT ...

WENRA harmonized decommissioning reference levels report - 19 -
1. Safety area: Safety management
1.1. Safety issue: Responsibility
D-01: A licensee 1 shall be responsible for all aspects of nuclear safety on the facility. The
continuity of responsibility shall be ensured throughout operation and decommissioning. In
accordance with the graded approach, the decommissioning strategies and plans necessary to
ensure safety shall be commensurate with the scale of the facility and the type of the
inventory.
Related IAEA safety standards:
... The operator is also responsible for all aspects of safety and environmental protection during the
decommissioning activities ... (DS 333, para 3.7).
D-02: The ultimate responsibility for safety shall remain with the licensee, although it is
permissible to delegate the performance of specific tasks to a subcontractor. The licensee shall
ensure that the work of contractors is appropriately controlled so that it is conducted safely.
Related IAEA safety standards:
The ultimate responsibility for safety shall remain with the operator, although it is permissible to delegate the
performance of specific tasks to a subcontractor. The decommissioning management shall ensure that the work
of contractors is appropriately controlled so that it is conducted safely... (DS 333, para 7.2)
D-03: The licensee shall provide financial assurances and resources to cover the costs
associated with safe decommissioning, including management of resulting radioactive waste.
Related IAEA safety standards:
... The operator shall provide financial assurances and resources to cover the costs associated with safe
decommissioning, including management of resulting radioactive waste. (DS 333, para 3.7).
1.2. Safety issue: Organisational structure
D-04: The licensee shall establish an organizational structure for the management and
implementation of decommissioning, with the responsibility to ensure that decommissioning
will be conducted safely.
Related IAEA safety standards:
An organization for the management and implementation of decommissioning shall be established as part of the
operator’s organization, with the responsibility to ensure that decommissioning will be conducted safely... (DS
333, para 7.1)
D-05: The adequacy of the organisational structure, for safe and reliable decommissioning of
the facility, and for ensuring an appropriate response in emergencies, shall be assessed on a
regular basis and in particular, if there is a major change in the plant state or hazard.
Related IAEA safety standards:
A safety assessment should form an integral part of the decommissioning plan. The operating organization is
responsible for preparing the safety assessment and submitting it for review by the regulatory body. The safety
assessment should be commensurate with the complexity and potential hazard of the installation and, in case of
deferred decommissioning, should take into account the safety of the installation during the period leading up to
final dismantling. (WS-G-2.1, para 5.3)
