Cel
Securing the nuclear fuel supply for European research reactors is the overall objective of the LEU-FOREvER project. Our analysis points out two main risks of shortage: (i) the very challenging conversion of High Performance Research Reactors (HPRRs) from High to Low Enriched Uranium fuels (LEU), (ii) the ROSATOM monopoly to fuel medium power research reactors (MPRRs) with original Soviet design.
On HPRRs, a multi-disciplinary consortium composed of fuel/core designers, operators and fuel manufacturer has been built to tackle both issues. Five European organisations (AREVA NP, CEA, ILL, SCK•CEN, TUM), which compose the HERACLES group, have been strongly involved for almost 20 years now in the development of LEU fuels. To enter the qualification phase in 2021, HERACLES is pushing towards the completion of an understanding phase. The baseline lies on the development of UMo fuels and their variants. Within LEU-FOREvER, optimisation of both manufacturing process (up to the design of pilot equipment) and modelling of the in-pile behaviour of these fuels are proposed. As a result of an independent review undergone in 2015, an alternative to UMo fuels has to be considered: this will be high-loaded U3Si2. Within LEU-FOREvER, it will be optimised to prepare an ambitious in-pile test (“High PROSIT”).
For European MPRRs, the ultimate goal is to design a new core which could work with both the original ROSATOM and European elements that would be developed, licensed and qualified (“4EVERTEST”) within LEU-FOREvER. The Czech LVR-15 reactor (CV Rez) has been selected as a case study, and preliminary design by AREVA-TA is based on U3Si2/Al flat fuel plates. To improve economic competitiveness, AREVA NP will reinvestigate its manufacturing process and propose optimisations.
Strong synergies are expected between both activities.
The modernization of research reactors appears as a key element in the mitigation of the risks surrounding the supply of isotopes, as expressed in the NFRP-11 topic.
