Machine for Disassembly, Examination, and Reassembly of Fuel Bundles

摘要

The Disassembly-Examination-Reassembly Machine (DERM) was developed as part of a program conducted for the Nuclear Regulatory Commission by Battelle's Pacific Northwest Laboratory. The program is to determine the effects of loss of coolant accidents on nuclear fuel. The experiments are conducted in the National Research Universal Reactor (NRU) at Chalk River Ontario, Canada. The DERM allows a complete profile to be taken in two weeks time. It is the first detailed mapping system that allows cross-section analysis of a fuel bundle. And it enables researchers to reuse portions of the test hardware. (ERA citation 08:014848)
