Optimization of Fuel Assembly Allocation for Boiling Water Reactors

REACTOR PHYSICS CALCULATIONS ON MOX FUEL IN BOILING WATER REACTORS (BWRs)

The loading of MOX (Mixed Oxide) fuel in BWRs (Boiling Water Reactors) is considered in this paper in a “once-through” strategy. The fuel assemblies are of the General Electric 8×8 type, whereas the reactor is of the General Electric BWR/6 type. Comparisons with traditional UOX (Uranium Oxide) fuel assemblies revealed that the loading of MOX fuel in BWRs is possible, but this type of fuel creat...

Modal 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 ...

Decommissioning Level 2 Probabilistic Risk Assessment Methodology for Boiling Water Reactors

This paper describes a methodology to evaluate the radiological risk of postulated accident scenarios during the decommissioning phase of commercial nuclear power plants. The fuel damage scenarios include those initiated while the reactor is permanently shut down and the spent fuel is initially located in the reactor pressure vessel and successively moved in the spent fuel storage pool. This pa...
