SCOPE AND RESPONSIBILITY
IWA-1100 SCOPE
This Division provides requirements for inservice
inspection and testing of light-water cooled nuclear
power plants. The requirements identify the areas subject
to inspection, responsibilities, provisions for accessibil-
ity and inspectability, examination methods and proce-
dures, personnel qualifications, frequency of inspection,
record keeping and report requirements, procedures
for evaluation of inspection results and subsequent
disposition of results of evaluations, and repair/replace-
ment activity requirements, including procurement, de-
sign, welding, brazing, defect removal, installation,
examination, and pressure testing.
IWA-1200 JURISDICTION
The jurisdiction of this Division covers individual
components and complete plants that have met all the
requirements of the Construction Code, commencing
when the Construction Code requirements have been
met, irrespective of physical location. When portions
of systems or plants are completed at different times,
jurisdiction of this Division shall cover only those
portions for which all of the construction requirements
have been met. Prior to installation, an item that has
met all requirements of the Construction Code may be
corrected using the rules of either the Construction
Code or this Division, as determined by the Owner.
IWA-1300 APPLICATION
IWA-1310 COMPONENTS SUBJECT TO
INSPECTION AND TESTING
Components identified in this Division for inspection
and testing shall be included in the inservice inspection
plan. These components include nuclear power plant
items such as vessels, containments, piping systems,
pumps, valves, core support structures, and storage
tanks, including their respective supports. The selection
of components for the inservice inspection plan is
11
subject to review by the regulatory and enforcement
authorities having jurisdiction at the plant site.
IWA-1320 CLASSIFICATIONS
(a) Application of the rules of this Division shall
be governed by the group classification criteria of the
regulatory authority having jurisdiction at the plant site
as follows.
(1) The rules of IWB shall be applied to those
systems whose components are classified ASME Class 1.
(2) The rules of IWC shall be applied to those
systems whose components are classified ASME Class 2.
(3) The rules of IWD shall be applied to those
systems whose components are classified ASME Class 3.
(4) The requirements of IWE shall be applied to
components classified ASME Class MC and to metallic
shell and penetration liners classified ASME Class CC.
(5) The requirements of IWF shall be applied to
supports classified ASME Class 1, 2, 3, or MC.
(6) The requirements of IWL shall be applied to
reinforced concrete and post-tensioning systems classi-
fied ASME Class CC.
(b) Optional construction of a component within a
system boundary to a classification higher than the
minimum class established in the component Design
Specification (either upgrading from Class 2 to Class
1 or from Class 3 to Class 2) shall not affect the
overall system classification by which the applicable
rules of this Division are determined.
(c) Where all components within the system bound-
ary or isolable portions of the system boundary are
classified to a higher class than required by the group
classification criteria, the rules of IWA-1320(a) may
be applied to the higher classification, provided the
rules of the applicable Subsection are applied in their
entirety.
(d) The portion of piping that penetrates a contain-
ment vessel, which is required by Section III to be
constructed to Class 1 or 2 rules for piping and which
may differ from the classification of the balance of
the piping system, need not affect the overall system
