Loose Parts Monitoring System

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.
