AB  - FANT (Fuente Ampliada de Neutrones Termicos; in Spanish) is a thermal neutron 
      irradiation facility with an extended and very uniform irradiation area, that has 
      been developed by the Neutron Measurements Laboratory of the Energy Engineering 
      Department at Universidad Politecnica de Madrid (LMN-UPM). This device is a 
      parallelepiped box made of high-density polyethylene (HDPE), moderator material, 
      that uses an A95241m/B49e neutron source of 111 GBq nominal activity for 
      irradiating materials. The facility design was previously optimized, and the 
      neutron spectra were estimated by extensive calculations with the MCNP6.1 code 
      and carrying out experimental measurements (Bedogni et al., 2017). The facility 
      takes advantage of the scattering reactions of neutrons with the HDPE surfaces of 
      the chamber, where the moderation process is effective, achieving relevant 
      thermal neutron fluence rates. The main goal of this work has been to simulate 
      and analyse the FANT system by Monte Carlo methods using the MCNP6.1 code, 
      employing 3 different nuclear data libraries: ENDF/B-VII.1, JEFF-3.3 and TENDL 
      2017. The transport of thermal neutrons in HDPE, E < 1eV, has been calculated in 
      all the cases taking into account the thermal S (alpha,beta) treatment. The results 
      achieved in this work have been compared with those previously obtained in the 
      former development of FANT, using the MCNP6.1 code with the ENDF/B-VII.1 nuclear 
      data, and experimental measurements. These results have shown that the JEFF-3.3 
      nuclear data library is the nuclear data library that provides of the best 
      matching between the MCNP computational results, and the experimental data 
      collected at FANT. Hence, the JEFF-3.3 nuclear data library seems to be the most 
      correct library to design and benchmark thermal neutron activation devices.
