In the framework of CAMP and OECD/NEA ROSA projects a broad analysis of Lower Head SBLOCA with High Pressure Safety Injection (HPSI) unavailable in a Westinghouse PWR has been performed. The simulations have been performed with TRACE 5 patch1 and the selected methodology has been the Integrated Safety Assessment (ISA) methodology, developed by the Spanish Nuclear Safety Council (CSN), which allows obtaining the damage domain as a function of the operator actuation times. The objective of this work is to find the available time for accident management actions by means of ISA methodology. The main conclusions are that present emergency operating procedures are adequate for this kind of sequences and there is not necessary to modify them and also that, the ISA methodology is adequate to analyze safety issues that include time delays uncertainties.
