Technical solutions for the management of radioactive waste (RAW): overview and methods of selection

A. BYCHKOV, Z. DRACE and M. I. OJOVAN, International Atomic Energy Agency (IAEA), Austria DOI: 10.1533/9780857097446.1.115 Abstract: Technical options for waste streams which arise from nuclear applications, research, power generation, nuclear fuel cycle activities and decommissioning of nuclear facilities as well as NORM-containing waste, are summarized. Since optimal selection of technical options is case specific to the waste management needs, […]

Radioactive waste (RAW) conditioning, immobilization, and encapsulation processes and technologies: overview and advances

C. M. JANTZEN, Savannah River National Laboratory, USA, W. E. LEE, Imperial College London, UK and M. I. OJOVAN, University of Sheffield, UK DOI: 10.1533/9780857097446.1.171 Abstract: The main immobilization technologies that have been demonstrated for radioactive waste disposal are cementation, bituminization, and vitrification. Vitrification is currently the most widely used technology for the treatment of high level radioactive wastes (HLW) […]

Stress corrosion and hydrogen-induced cracking of carbon steel and stainless steel

This section presents the SCC behaviour of carbon steel disposal containers and stainless steel storage canisters. Carbon steel is mostly susceptible to hydrogen-induced cracking due to residual weld (and heat affected zone) stress or seismic-induced impact stress. Hydrogen is generated during general corrosion or gamma radiolysis of groundwater in a reducing envi­ronment (Ahn and Soo, 1995).

Safety and risk assessment of radioactive waste (RAW) and contaminated sites

Y. V. PUZANOV, SUE SIA ‘Radon’, Russia DOI: 10.1533/9780857097446.1.327 Abstract: The axiomatic basics of quantitative safety/risk assessments are discussed. Deterministic and probabilistic analysis methods are then introduced. As an illustrative example, safety assessment for the environment is given in terms of the probability of radionuclide escape from a near-surface disposal facility. Emergency accident levels are correlated with the probabilities of […]
