1 Scope
This International Standard provides strategies, technical requirements, and recommended
practices for the management of normal ageing of cabling systems that are important to safety in nuclear power plants. The main requirements are presented
in the body of this International Standard followed by a number of informative annexes
with examples of cable testing techniques, procedures, and equipment that are available
for the nuclear industry to use to ensure that ageing degradation will not impact
plant safety.
This International Standard covers cables and their accessories (e.g., connectors)
installed in nuclear power plants (inside and outside the containment). It provides
requirements to perform cable testing for the purposes of predictive maintenance,
troubleshooting, ageing management , and assurance of plant safety. It is concerned with Instrumentation and Control
(I&C) cables, signal cables, and power cables of voltages less than 1 kV. More specifically,
this International Standard focuses on in-situ testing techniques that have been established
for determining problems in cable conductors (i.e., copper wire) and, to a lesser
extent, on insulation material (i.e., polymer). It follows the IEC 62342 standard on “Management of Ageing” that was prepared to provide general guidelines
for management of ageing of I&C components in nuclear power plants, including cables.
It should be pointed out that cable testing technologies are evolving and new methods
are becoming available that are not covered in this International Standard. More specifically,
this International Standard covers typical cable testing methods that have been in
use in the ...
