  We present a project dedicated to hot plasma spectroscopy based on a
Multi-Configuration Dirac-Fock (MCDF) code, initially developed by J. Bruneau.
The code is briefly described and the use of the transition-state method for
plasma spectroscopy is detailed. Then an opacity code for
local-thermodynamic-equilibrium plasmas using MCDF data, named OPAMCDF, is
presented. Transition arrays for which the number of lines is too large to be
handled in a Detailed-Line-Accounting calculation can be modeled within the
Partially-Resolved-Transition-Array method or using the
Unresolved-Transition-Arrays formalism in jj-coupling. An improvement of the
original Partially-Resolved-Transition-Array method is presented which gives a
better agreement with Detailed-Line-Accounting computations. Comparisons with
some absorption and emission experimental spectra are shown. Finally, the
capability of the MCDF code to compute atomic data required for
collisional-radiative modeling of plasma at non local thermodynamic equilibrium
is illustrated. Additionally to photoexcitation, this code can be used to
calculate photoionization, electron impact excitation and ionization
cross-sections as well as autoionization rates in the Distorted-Wave or Close
Coupling approximations. Comparisons with cross-sections and rates available in
the literature are discussed.
