During the past few weeks we had the great pleasure to receive two new members in our group. Valeria and Mariana are undergraduate students with a major in Materials Science. Whereas Valeria comes from Saltillo Coahuila, the city where we are based, Mariana is visiting us from Chihuahua. Both students will be working on diffusion issues relate to TRISO coated fuel particles. Valeria already worked with us last year during her summer internship, so I am very happy to have her back. I hope they enjoy their stay at CINVESTAV.
