Regulatory oversight of nuclear safety in Finland. Annual ... - STUK

wards data on activities relating to the nuclear
fuel cycle in Finland to the International Atomic
Energy Agency (IAEA). STUK verifies the correctness
of the notifications, accounting and reporting
through on-site inspections and participates in
all inspections carried out by the IAEA and the
European Commission.
The National Data Centre (NDC), which is
based on the CTBT, contributed to the work of the
Preparatory Commission for the Comprehensive
Nuclear-Test-Ban Treaty Organisation (CTBTO) in
establishing a cost-effective NDC organisation that
is functional from the Finnish perspective.
Oversight of nuclear waste management
extends from planning to final disposal
The aim of the regulation of nuclear waste management
is to ensure that nuclear waste is processed,
stored and disposed of safely. The control of nuclear
waste processed at plant sites is part of the regulatory
STUK-B 147
control of operating plants mentioned above. STUK
oversees the nuclear waste management of nuclear
power plants through document reviews and inspections
within the periodic inspection programme. In addition,
STUK approves the clearing of waste from control
and reviews plants’ nuclear waste management
and decommissioning plans, on the basis of which the
licensees’ nuclear waste management fees are determined.
The final disposal project for spent fuel requires
special attention. STUK inspects and reviews
Posiva Oy’s plans and research work for project implementation
and is overseeing the construction of
an underground research tunnel called Onkalo at
Olkiluoto. Onkalo is also being used to test suitable
working methods for the final disposal facility and
mapping the underground premises. The plan is to
later convert the research tunnel into an entrance
for the repository.
