In the UK nuclear context, it is a standard requirement for licensed sites that "The licensee shall make and implement adequate arrangements to ensure that only suitably qualified and experienced persons perform any duties which may affect the safety of operations on the site or any other duties assigned by or under these conditions or any arrangements required under these conditions.".
In this context the term is not restricted to professionally qualified personnel or to duties requiring significant technical expertise: any means any It is essential that all personnel whose activities have the potential to impact on nuclear safety are suitably qualified and experienced (SQEP) to carry out their jobs.
[2] and conversely suitably means suitably, not particularly well: the Office of Nuclear Regulation takes SQEPness to be broadly equivalent to the International Atomic Energy Agency concept of 'competence' IAEA has defined competence as "the ability to put skills and knowledge into practice in order to perform a job in an effective and efficient manner to an established standard" ONR concurs with this definition, which is widely accepted within the international nuclear community.
[2]In the context of UK nuclear licensing, the term "duly authorised person" (DAP) was extensively used for trained and experience operational staff, on plant or in control rooms.
SQEP was introduced for those staff who may not have direct responsibility on plant, but whose actions or input could be safety related.
