An emerging breeding blanket that fulfills performance criteria, meets the safety requirements, and is reliable enough to meet plant availability a challenging issue assumes complex studies involving numerous neutronic analyses based on Monte Carlo simulations with MCNP code. Two different concepts are now candidates be implemented as driver for DEMO fusion reactor: WCLL (Water-Cooled Lithium L...

This paper presents an assessment of three deterministic core simulators with the focus on neutronic performance in steady-state calculations small Sodium cooled Fast Reactor cores. The selected codes are DYN3D, PARCS and novel multi-physics solver GeN-Foam. By using these codes, multi-group diffusion solutions obtained for twenty control rod worth measurements performed during isothermal physi...

This paper describes steady-state reactor physics measurements and calculations that were performed for the Training Reactor of Budapest University Technology Economics (BME TR) with purpose benchmarking. Based on available geometry specifications material compositions a model BME TR was created well-validated, general-purpose Serpent 2 Monte Carlo code. Uncertain parameters (such as fuel densi...

Optimizing the use of fuel in a power reactor is task current concern. However, little attention has been given to investigating dependences among enrichment used, content gadolinium oxide elements, and life time combination with assessing efficiency using Gd elements different 2 O 3 contents. The paper considers assembly (FA) versions for VVER-1200 reactors having enrichments including those G...

For the purpose of developing the capability to produce fission Mo, the Chilean Nuclear Energy Commission is participating in the IAEA Coordinated Research Project: “Developing Techniques for Small Scale Indigenous Mo-99 Production using LEU Fission or Neutron Activation”. Fission Mo will be produced irradiating, at RECH-1 reactor, a target made of a LEU metallic uranium foil held between two c...
