As can be seen in Table 2.1–1, for the first two units of the Fukushima Daiichi NPP, the original design basis values are quite modest, with about 0.25g for the zero period ground acceleration and with 0.47g for the static horizontal acceleration. The latter is applied for specific design purposes of the building and structures as part of the seismic design process of Japanese NPPs, which is quite conservative, follows three distinct paths and chooses the most conservative result. |
