Innovative technologies for spent fuel safe management at Ignalina channel-type reactors

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 ...

Thermal assessment of new Ignalina NPP casks for spent nuclear fuel storage at some abnormal conditions

For interim storage of spent nuclear fuel (SNF) at the Ignalina Nuclear Power Plant (INPP), the so-called “dry” storage technology has been chosen. In this case, SNF after a cooling (pre-storage) period in water pools (no less than 5 years) is placed into GNS (Germany) manufactured metal CASTOR ® RBMK-1500 or reinforced concrete CONSTOR ® RBMK-1500 casks and may be stored for at least 50 years ...

Potential Radioactive Releases from Commercial Reactors and Spent Fuel*

Commercial nuclear reactors and storage facilities for their spent fuel contain large amounts of radioactive material, and are not designed to resist attack. The US Nuclear Regulatory Commission (NRC) has determined, however, that these facilities require only a light defense. This paper shows, without disclosing any sensitive information, that reactors and spent-fuelstorage facilities have vul...

Innovative Technologies for Nuclear Fuel Cycles and Nuclear Power

At the present stage of development no single energy resource or technology constitutes a panacea toaddress all issues. Therefore, it is necessary that all low-carbon and non-carbon emitting resources become anintegral part of an energy mix – as diversified as possible – to ensure energy security to the world during thepresent century. Available sources are low carbon fossil fuels, ...
