During 2006 several activities related to RERTR topics are taking place: the progress on the conversion project of the RA-6 core reactor from HEU to LEU, where CNEA has minimized the HEU inventory plates by swapping them for LEU material to fabricate the new LEU core; LEU UMo and UZrNb monolithic miniplates using Zry-4 cladding are being produced for its irradiation in ATR and RA-3 reactors, in the first case as a part of the RERTR 9 irradiation experiment. U-Mo/Al-Si and U-Mo/ Zry-4 compounds using atomistic modeling prediction (BFS techniques and first principles) were studied, finding some trends on the interaction phases, which were found on diffusion couples tests and were characterized. Cold process to treat and recover actinides from Zry-4 cladding U-Mo monolithic miniplates was started and has promissory first results. Progress on LEU technology for radioisotope production: since September 2005, CNEA began the regular production of high quality fission I131, a by-product of Mo-99 production, meeting international quality standards.
