Descrizione e Attività
Descrizione Generale
The PUMMA project will define different options for Pu management in Generation-IV systems and evaluate the impact on the whole fuel cycle in addition to safety and performance aspects.
Fast neutron reactors with the associated fuel cycle strategy have been chosen to cope with these options because they are flexible: they offer the possibility of isogeneration, burning or breeding of plutonium.
A wide range of Pu content (20 to 45%) corresponds to the highest concentration that can be encountered for plutonium multirecycling (~30-35% Pu to compensate degraded isotopic composition) and targeted plutonium burning (40-45%).
The fuel cycle scenarios associated with the different strategies will be evaluated at different stages of the cycle in terms of impact on the facilities. These studies will be completed with dissolution tests as there is currently no dissolution data on fuels with very high plutonium contents. Studies to date have been limited to concentrations of less than 30%.
Today, knowledge on MOX fuel behavior in Generation-IV reactors comes mainly from feedback on SFRs that have operated in the past in Europe, with Pu contents varying between 15% to 30% and Linear Heat Rate often in the 300 to 450 W/cm range. This knowledge is insufficient to cover future needs, whether in terms of reactor concepts (GFR, LFR, F-SMR ...), Pu management option or operating regime. PUMMA will provide complementary results on fuel properties and characterisations of 45%Pu-fuels irradiated in HFR and Phénix under nominal conditions and overpower. The safety standards will then be extended to this fuel composition as well as the fuel performance code validation.
PUMMA will make the link between Europe and others international organisations: the fuel cycle studies at IAEA and OECD, the GEN-IV systems at ESNII and GIF, the fuel material studies at OECD.
PUMMA will provide common data in E.U. for Pu management on : fuel cycle, fuel behavior, fuel properties and safety st-
Attività svolta da ENEA
Nell’ambito del progetto PUMMA è assegnato ad ENEA il coordinamento della Task 4.1 “Irradiation in MTR vs FR: comparison of irradiation conditions”,
ENEA è coinvolta nel progetto come partecipante dei Work Package 2 (“Fuel Pin behaviour in reactor with high Pu content: Nominal and transient”), 3 (“Fuel properties with high PU content: Measurements and modelling”), con anche il compito di organizzare e ospitare un Workshop di progetto, dedicato alle proprietà del combustibile nuclearei interesse, dal punto di vista della sua fabbricazione, misura e modellazione.
ENEA è stata proposta per ospitare il quarto Workshop tematico (Task 6.2): Workshop 4 on fuel properties: fabrication & modelling & measurements – Uncertainties reduction and impact on safety margins.
