Mechanical decontamination of condensate pipes in Gundremmingen NPP

With the re-equipment of turbine condensers in boiling water reactors large quantities of outside weak contaminated brass tubes come up. For the decontamination of these tubes Babcock Noell nuclear developed, built an operated a mechanical decontamination plant for the nuclear release of the tubes after measurement for conventional utilisation. The pipes are decontaminated by brushing and grinding in order to be finally under the release limits. Almost no secondary waste come up with this procedure. The treaded pipes can be used for conventional purposes.

Performance characteristics:

Campaign: 280 to
Throughput: 2,5 - 3 to / Tag
Primary waste: < 1%
free release measurement  mass-specific and surface-specific
