Characterization of neutron fields around refurbishment waste at Bruce Power and OPG using neutron spectrometry and Monte Carlo modelling
Using neutron spectrometry, we characterized the neutron energy spectra coming from irradiated components of a refurbished CANDU reactor. The measured neutron energy spectra were from refurbishment waste from calandria tubes (CTs) and pressure tubes (PTs). The measurements were conducted using a Nested Neutron Spectrometer (NNS), manufactured by Canadian company DETEC Inc. They were performed at […]
Decommissioning Techniques – 200 Series, Chalk River Labs
Canadian Nuclear Laboratories’ (CNL) Chalk River Campus is home to a cluster of connected facilities, commonly known as the 200 series buildings, comprised of B200A/B, B204, and B220. These facilities are currently undergoing active decommissioning by the Facilities Decommissioning group. The 200 series buildings housed and processed spent fuel rods from the National Research Experimental […]
Decommissioning of Complex Nuclear Sites
A complex nuclear site is one that houses several nuclear facilities on a single site. Often these include different types of facilities (e.g. reactors, heavy water processing & storage and waste management) in several lifecycle stages (construction, operations, refurbishment and decommissioning). Interferences between them are possible and decommissioning often suffers from a lower priority. CSA […]
