MODELLING OF NUCLEAR FUEL CLADDING TUBES CORROSION

Behaviors of Nuclear Fuel Cladding During RIA

Recycle of Zirconium from Used Nuclear Fuel Cladding:

Feasibility tests were initiated to determine if the zirconium in commercial used nuclear fuel (UNF) cladding can be recovered in sufficient purity to permit re-use, and if the recovery process can be operated economically. Initial tests are being performed with unirradiated, non-radioactive samples of various types of Zircaloy materials that are used in UNF cladding to develop the recovery pro...

Radiation Induced Corrosion of Nuclear Fuel and Materials

In some cases, a corrosion system may be exposed to radiation field. Most usually, it occurs as a part of atmospheric corrosion, when materials are, besides other factors, exposed also to visible and ultraviolet radiation. Technical significance of corrosion caused by such types of radiation is rather small. On the other hand, metallic materials may be exposed to high energy ionizing radiation ...

Uranyl peroxide enhanced nuclear fuel corrosion in seawater.

The Fukushima-Daiichi nuclear accident brought together compromised irradiated fuel and large amounts of seawater in a high radiation field. Based on newly acquired thermochemical data for a series of uranyl peroxide compounds containing charge-balancing alkali cations, here we show that nanoscale cage clusters containing as many as 60 uranyl ions, bonded through peroxide and hydroxide bridges,...

Inhibition of cut edge corrosion of coil-coated architectural cladding

This study has investigated the solubility of inhibiting pigments and also the leaching behaviour of corrosion inhibitors from a polyester binder in an acid rain solution. This study has relevance to the control of cut-edge corrosion by inhibitor pigments, which are incorporated into the primer coatings of coil-coated architectural cladding. The concentrations of leachate solutions in tubes glu...
