In this report, we have reviewed the basic features of the accident processes and radioactivity releases that occurred in the Chernobyl accident (1986) and in the Fukushima-1 accident (2011). The Chernobyl accident was a power-surge accident that was caused by a failure of control of a fission chain reaction, which instantaneously destroyed the reactor and building, whereas the Fukushima-1 acci...

It is generally acknowledged that LMFBRs would be superior TRU transmutation devices, mainly due to their hard neutron spectrum. In the present study, the characteristics of TRU transmutation in a 1000 MWe-class LMFBR with mixed-oxide(MOX) fuel were quantitatively investigated to substantiate the feasibility. We considered here two typical methods transmuting TRU in the LMFBR core. One is the m...

The steam reforming of hydrocarbon fuels is a promising method for the production of hydrogen for portable electrical power sources. A suitable reactor for this application, however, must be compatible with temperatures above 800 degrees C to avoid coking of the catalytic structures during the reforming process. Here, ceramic microreactors comprising high surface area, tailored macroporous SiC ...

Abstract The austenitic stainless steel 15-15Ti is one of the main candidate materials for fuel cladding Lead-cooled Fast Reactor (LFR) due to its outstanding irradiation resistance and mechanical properties at high temperatures. study corrosion behavior in LBE can help further investigate service performance a reactor. In this study, static 15−15Ti was carried out 1000 h temperature 550°C oxyg...

We evaluated the activity of (1) amphotericin-B (AMB), combined with rifampicin (RIF), clarithromycin (CLA), N-acetylcysteine (NAC), ethylenediaminetetraacetic acid (EDTA), and farnesol (FAR) (1000, 1000, 1000, 4000, and 30,000 mg/L, and 300 µM, respectively), against Candida tropicalis biofilms formed on polytetrafluoroethylene (PTFE) and (2) anidulafungin (ANF) combined with the same compound...

This work deals with the validation of a high-fidelity multiphysics system coupling Serpent 2 Monte Carlo neutron transport code SUBCHANFLOW, subchannel thermalhydraulics code, and TRANSURANUS, fuel-performance analysis code. The results for full-core pin-by-pin burnup calculation ninth operating cycle Temelín II VVER-1000 plant, which starts from fresh core, are presented assessed using experi...
