Defect Description An description of the defect types that may occur in
the component(s) that the inspection qualification
shall be valid for. The defect description includes all
defects that reasonably could exist in the component,
even those that will not be included in the
inspection (e.g. certain manufacturing defects).
Those defects that are to be included in the inspection
and thus in the qualification, shall be identified
These shall be described in detail with regard to
orientation and other characteristics, such as type
(crack like / volumetric), morphology (smooth /
rough crack surface), tilt, skew, etc. The defect description
is then the basis for the defect specification,
which describes the defects in the test blocks
for the practical demonstrations.
Defect Specification A specification for the manufacture of test pieces
which exactly describes the types, sizes, number
and location of defects in a test piece intended for
practical demonstration. Defect specifications for
open test blocks are the responsibility of the licensee,
usually in collaboration with the inspection
vendor (accredited laboratory).
Design Criteria For the sub-area mechanical integrity the design
criteria are defined as the design basis and includes
events, loads, load overpressurisation protection
criteria and the evaluation thereof.
Note: See also the definition of design specification
Design review Review that the manufacturing documents fulfil
specified requirements. It is performed by an accredited
body or in special cases as In-house review.
Design Specification A document containing all necessary information
for making a design. The design specification consists
of a general description and design conditions
for sub-areas. Instances of sub-areas are: function,
capacity, mechanical integrity, reactor safety,
maintenance and environment.
Sub-areas to be regarded are those needed for a total
function.
Detection To correctly determine the existence of a defect and
its location through Analysis of the NDT data according
to the criteria within the NDT procedure.
