Resumen
The neutron fields alter the radioactive inventory of the irradiated materials leading to subsequent
decay photon fields. In some cases, these fields are of relevance either intended or undesired, normally involving
safety and economics aspects. The determination of these fields can be of paramount complexity if high spatial
resolution is required. The determination of these fields requires both radiation transport and activation
calculations. The Direct-one-Step methodology, under the assumption that the radioactive inventory activity is
lineal with the neutron flux, can address the problem with only one coupled neutron-photon transport calculation.
In this paper the D1SUNED code for the calculation of decay photon field and related quantities using D1S
methodology is presented. Calculation capabilities including the determination of 3D decay photon sources,
filtering options, and other relevant features are presented. In terms of computational load, D1SUNED, which is
based on MCNP5 code, presents improvements with respect to MCNP. It can save a 79% of the RAM memory
used to store the geometry, a 98% of the loading time, and an acceleration of a factor two by controlling the decay
photon emission, boosting the simulations for ITER-like problems. D1SUNED has been validated with the FNG
benchmark experiment considering the null hypothesis rejection test and the C/E ratio with very positive results.
As a consequence, D1SUNED has become a reference tool for the design of ITER, and other relevant nuclear
fusion facilities.
