shielding and criticality safety analyses for spent fuel transportation cask in tehran research reactor
in this research, shielding and criticality safety calculations carried out for interim storage and transportation cask in the tehran research reactor. such dual purpose cask is being designed to the spent fuel elements of research reactors. the monte carlo mcnp5 code calculation was utilized for the criticality safety analysis and origen2.1code was used for shielding calculation. according to ...
متن کاملModal Analysis of Spent Fuel Cask for WWER-1000 Reactors
The Spent Fuel Assemblies (SFAs) of WWER-1000 reactors are planned to be transported by special containers which are supposed to be designed in a manner to stand against vibrations and impacts in order to protect the spent fuel from any possible damage. The vibration opposition of these containers shall be far beyond the critical resonance, because the resonances about the natural frequency of ...
متن کاملAN APPROACH FOR VALIDATING ACTINIDE AND FISSION PRODUCT BURNUP CREDIT CRITICALITY SAFETY ANALYSES – CRITICALITY (keff) PREDICTIONS
One of the most significant remaining challenges associated with expanded implementation of burnup credit in the United States is the validation of depletion and criticality calculations used in the safety evaluation—in particular, the availability and use of applicable measured data to support validation, especially for fission products. Applicants and regulatory reviewers have been constraine...
متن کاملTransnuclear West Attachment 5 Ornl / Tm - 1293
Spent fuel transportation and storage cask designs based on a burnup credit approach must consider issues that are not relevant in casks designed under a fresh-fuel loading assumption. For example, the spent fuel composition must be adequately characterized and the criticality analysis model can be complicated by the need to consider axial burnup variations. Parametric analyses are needed to ch...
متن کاملInvestigation of the required thickness of thorium spent fuel lead transport cask depending on different fuel burnups and cooling times
Thorium fuels have attracted researcher’s attention due to the reduction of uranium deposits in the world, more abundances than uranium, and the ability to be breeding in thermal and fast reactors. This study aimed to investigate the radiation safety and the amount of necessary shielding for the transportation of spent thorium fuel in the Tehran Research Reactor. The ORIGEN and MCNPX computatio...
