Impacting loose parts, sliding and rolling actions,
cavitation, etc. generate structure-borne noise bursts
in the reactor coolant system of nuclear power plants
which propagate through the plant structure. The
KÜS loose parts monitoring system detects and
records these bursts, analyses them, locates their
origin and thus provides information on the operating
condition of components.

The prompt and reliable detection of loose parts
entrained in the coolant prevents sequential damage
such as damage to fuel assemblies, pump blades,
cladding or to the roller expanded tube sections in
the steam generator tubesheet.
