TY - CONF TI - Contribution at the evaluation of safety softwares in nuclear power plants control systems; Contribution a l`evaluation des logiciels de surete du controle-commande des centrales nucleaires AB - The introduction of programmable systems such the SPIN (Numerical Integrated Protection System) has conducted at particular dispositions for the conception and the use of such systems. The utilization of such systems until 1983 has conducted at modifications in the maintenance procedures. The new methods used for the N4 project in the evaluation of safety softwares are given in this report.
