Modelling of Fission Gas Behaviour in High Burnup Nuclear Fuel

The safe and economic operation of nuclear power plants (NPPs) requires that the behaviour and performance of the fuel can be calculated reliably over its expected lifetime. This requires highly developed codes that treat the nuclear fuel in a general manner and which take into account the large number of in uences on fuel behaviour, e.g. thermal, mechanical, chemical, etc. Although many mature...

Nitride Fuel and Pyrochemical Process Developments for Transmutation of Minor Actinides in Jaeri

The Japan Atomic Energy Research Institute (JAERI) has proposed the concept of the transmutation of minor actinides (MA: Np, Am and Cm) with accelerator-driven systems (ADS), where MA nitride is adopted as a fuel material of a sub-critical core, because nitride fuel has the advantage of accommodating various MAs with a wide range of composition besides superior thermal and neutronic properties....

Mass Balance of the Pu and Minor Actinides Recycling Metal Fuel System

The mass flow of Plutonium and minor actinides is calculated for a future LWR-FBR fuel cycle model, in which a certain scale of power generation by LWRs is continued for a long period before the replacement by FBRs begins. The burnup of the LWR spent fuel is considered to be higher than the current standard. It is assumed that all the Plutonium and minor actinides recovered from LWRs are kept a...
