A new strategy in safety evaluation using probabilistic risk assessment

The factors affecting the regulation and its modifications of the nuclear industry in the USA are described and criticized. The results produced, as Mexico follows the same rate of change in the norms for evaluating safety in the Laguva Verde Nuclear Power Plant are analyzed. The use of probabilistic risk assessment are analyzed 'engineering applications', in nuclear power plant safety evaluation, are described. A new safety-evaluating strategy for the PNLV is proposed. This strategy basically consists in the establishment of a fixed regulating frame of reference and the dynamic evaluation using probabilisitic risk assessment of the safety aspects that have appeared and are still appearing outside the frame.
