Comparison of different dismantling cutting tools in the same experimental conditions.
G. Pilot, MOL (Belgique), 18-22/11/2002.
For decommissioning programmes, numerous studies have been carried out on cutting tools, but it is often difficult to compare the results of different studies because the tools were implemented under a wide range of conditions. The purpose of this investigation was therefore to compare various cutting tools under standard conditions of use, and thus to allow realistic assessments for consideration in decommissioning scenarios.
The comparison covers both cutting performance and secondary waste generation, with particular emphasis on the following parameters: cutting speed, secondary waste distribution (sedimented dross, cell wall deposits, aerosols) and, in some cases, characterization (particles size distribution, chemical composition).
All the tests were carried out under non-radioactive conditions in an airtight 32 m3 cell comprising modular stainless steel panels.
The tests were conducted on stainless steel and steel specimens between 0.2 and 20 cm thick using seven types of tools: reciprocating saw, disk grinder, plasma torch (50A and 200A), arc-air cutter, arc saw, lost wire pulsed oxycutting tool (LSI) and Nd-YAG laser.
