Radiological characterisation for the clearance of burnable waste produced at CERN / Harbron, Richard (CERN) ; Charousset, Renaud (CERN) ; Dumont, Gerald (CERN) ; Magistris, Matteo (CERN) ; Menaa, Nabil (CERN) ; Giunio Pisano, Paolo (CERN) ; Theis, Christian (CERN)
Burnable waste produced at CERN during upgrading, maintenance and dismantling campaigns may be contaminated with radioactive nuclides produced through activation of accelerator components. Here, we present a methodology for the radiological characterisation of burnable waste, which takes into account the wide range of potential activation conditions (beam energy, material composition, location, irradiation and waiting time). [...]

New methodology for in-situ classification of radiological items with a clearance monitor system / Frosio, Thomas (CERN) ; Menaa, Nabil (CERN) ; Dumont, Gérald (CERN) ; Aberle, Frédéric (CERN)
Maintenance activities and operations of high-energy particle accelerators can lead to the collection ofradioactive equipment as well as waste materials. In order to ensure their proper classification as radioactiveor non-radioactive, one has to quantify the activities of radionuclides produced. [...]

Radiological characterization of low- and intermediate level (LL/IL) radioactive waste / Dyrcz, Patrycja Kinga
In the framework of maintenance, upgrades and dismantling activities of particle accelerators, a number of activated components are removed from the accelerator complex and require radiological characterization before their disposal as radioactive waste [...]

Radiological characterization of targets from the ISOLDE facility at CERN / Magistris, M (CERN) ; Forkel-Wirth, D (CERN) ; Ulrici, L (CERN) ; Otto, T (CERN)
The European Laboratory for Particle Physics (CERN, Geneva) has been operating accelerators for high-energy physics both on Swiss and French territory for 50 years. Due to the interaction of the particle beams with matter, part of the accelerator structure and its surroundings become radioactive. [...]

Radiological clearance of historical waste from particle accelerators / Svihrova, Lucie (CERN ; Prague, Tech. U.) ; Bauer, Kerstin (CERN) ; Bruno, Luca (CERN) ; Dumont, Gerald (CERN) ; Magistris, Matteo (CERN) ; Menaa, Nabil (CERN) ; Silari, Marco (CERN) ; Ulrici, Luisa (CERN)
This paper presents a detailed methodology for reclassifying radioactive material from particle accelerators as non-radioactive, drawing on experiences at CERN. During particle accelerator decommissioning, the waste is classified based on its radioactivity level where the very-low-level activity material is the potential clearance candidate. [...]

Uncertainty quantification applied to the radiological characterization of radioactive waste / Zaffora, B (CERN) ; Magistris, M (CERN) ; Saporta, G (CNAM, Paris) ; Chevalier, J -P (CNAM, Paris)
This paper describes the process adopted at the European Organization for Nuclear Research (CERN) to quantify uncertainties affecting the characterization of very-low-level radioactive waste. Radioactive waste is a by-product of the operation of high-energy particle accelerators. [...]

In-toto non-destructive assay methodology for the elimination of metallic waste from particle accelerators after melting / Dyrcz, Patrycja (CERN) ; Menaa, Nabil (CERN) ; Magistris, Matteo (CERN) ; Theis, Chris (CERN) ; Bruno, Luca (CERN) ; Dumont, Gerald (CERN) ; Charousset, Renaud (CERN)
Melting of metallic waste reduces the waste volume, allows more accurate radiological characterization, and minimizes handling at the waste production site. This paper proposes a new non-destructive assay methodology to radiologically characterize low- and intermediate-level (LILW) waste before melting. [...]
