In the January 2002 issue of Nuclear Engineering International, we neglected to credit the author of the article entitled: “Hard guidelines made for computer software”.

The author was Pierre-Jacques Courtois, of the Association Vincotte Nuclear (AVN) in Brussels. He was a contributor to the two guidance documents and would like to make it clear that the article represents his personal opinion, and is not a complete analysis of their contents.

He wishes to thank J Pachner of the IAEA, J Gomez of the DG for Energy and Transports of the European Commission, Pierre Govaerts of AVN, Manfred Kersken of the ISTec, Germany, and Bob Yates of the NII, UK, for their useful comments on a previous version of the article.
