The aim of the shut down analysis was to produce a full Safety Analysis Report (SAR) for the shutdown and outage states including re-fueling. The SAR should contain both a deterministic and a probabilistic analysis (this is a requirement in Sweden today). The two analyses were performed in parallel with both common parts and common support activities. The probabilistic analysis should comprise both Level 1 and Level 2. The main intention of the parallel process was to form a homogeneous analysis, i.e. that equal limitations, conditions and assumptions were used. Another intention of the parallel process was to facilitate the...
