The neutron energy spectra have been calculated in the fuel region, inner and outer irradiation sites of the zero power research reactor using the MCNP-4C code and the combination of the WIMS-D/4 transport code for generation of group constants and the three-dimensional CITATION diffusion code for core analysis calculations. The neutron energy spectrum has been divided into three regions and co...

In this report the capability of various code systems widely used at PSI (such as WIMS-D, BOXER, and the AARE modules TRAMIX and MICROX-2 in connection with the one-dimensional transport code ONEDANT) and JEF-1 based nuclear data libraries to compute LWR lattices is analysed by comparing results from thermal reactor benchmarks TRX and BAPL with experiment and with previously published values. I...

Traditionally, Internet has offered multimedia services independently of the services offered by companies associated to Telco (companies that traditionally offer telephony and associated services). In the last years, the technical community has assumed that the convergence of both worlds is a fact; however, there are many barriers to be removed. On one hand the emergence of cloud computing tec...
