Qualitative evaluation of risks associated to non-nominal operation conditions of Vandellos-II

After the probabilistic analysis carried out for the Vandellos-II configuration under different operation modes, and also from the information of other studies and the Normatives requirements on IPE we concluded as neccesary the following scenarios: Scenario 1: Analysis of LOCAS under mode 5 with diminished technological safeguards since it is not required neither automatic our manually starting them by ETF or because of the possibility of having a configuration with an unique train of Residual Heat Removal (RHR) and level at the Steam Generator. Scenario 2: Losses of RHR under conditions of minimum inventory of the primary, that is to say, during half operation of the nozzle
