significance. This requires that the regulatory control is continually developed <strong>and</strong> that<br />
work contents of each employee are continually self-assessed. (Guide YTV 1.2).<br />
Documentation for the systems, structures <strong>and</strong> components of nuclear facilities to be<br />
sent for <strong>STUK</strong>’s review takes into account the safety classification. The documentation<br />
is the most comprehensive for Safety Classes I <strong>and</strong> II. This means also that <strong>STUK</strong>’s<br />
review activities are focused according to safety classes. The Guide YTV 6.1 emphasizes<br />
that safety significance shall be taken into account in the review of the documentation.<br />
Safety significance is also taken into account in <strong>STUK</strong>’s inspections .The basis for<br />
regulatory inspections is in the legislation <strong>and</strong> in YVL-guides which both include graded<br />
approach. Therefore the main inspection resources of <strong>STUK</strong> are allocated on the basis<br />
of safety classification (Guides YTV 4.6.1, YTV 4.6.2, YTV 4.5.2, YTV 5.2.1, YTV 4.6.3,).<br />
Inspection organizations (IO) approved by <strong>STUK</strong> carry out some inspections in the<br />
lower safety classes Guides YVL 1.1 <strong>and</strong> YVL 1.15 <strong>and</strong> internal guides YTV 4.5.5 <strong>and</strong><br />
YTV 4.5.8)<br />
<strong>STUK</strong> has also introduced a risk-based in-service inspections (RI-ISI). In this approach<br />
also PRA is used for determining safety relevance.<br />
Documentation for the safety arrangements for the use of radiation to be sent for<br />
<strong>STUK</strong>’s review takes into account the Safety Categories. The documentation is the most<br />
comprehensive for Category III. This means also that <strong>STUK</strong>’s review activities are<br />
focused according to Safety Categories (Guide SKV 3.2).<br />
Risk-based graded approach is applied in inspecting the use of radiation. This means<br />
that inspection frequencies depend on the risk posed by the activity, ranging from 2 to<br />
8 years.<br />

How is the graded approach reflected in the<br />
deployment of the regulatory resources across the<br />
different areas of regulatory activities?<br />
SQID 6.4<br />
Graded approach has been taken into account when planning <strong>and</strong> developing <strong>STUK</strong>’s<br />
resources in various regulatory activities in the fields of the use of radiation <strong>and</strong><br />
nuclear energy. This means that the main resources are allocated for the regulatory<br />
control on nuclear power plants.<br />
The prioritisation of activities <strong>and</strong> the most important objectives are set out in the<br />
strategy <strong>and</strong> related action programmes. They are taken into account in annual target<br />
plans. Performance reviews between superiors <strong>and</strong> employees are an essential part of<br />
the planning<br />
(Guide <strong>STUK</strong> 1.1).<br />
As regards nuclear facilities the main resources of <strong>STUK</strong> are allocated on the basis of<br />
safety classification. Risk-based categorization of the use of radiation is taken also into<br />
account in allocation of <strong>STUK</strong> resources in that area.<br />
Necessary factors for success of <strong>STUK</strong> are adequate human resources <strong>and</strong> professional<br />
competence in all areas relevant for radiation <strong>and</strong> nuclear safety. Maintaining <strong>and</strong><br />
developing human capital is supported by maps on competence needs <strong>and</strong> actual
