“…4.0 within 100km radius of the city. In this regard, DSHA pertaining to NPP at Kalpakkam site location was conducted by Anbazhagan et al (2013) and reported a safe shutdown earthquake (SSE) with a predicted Mw of 6.2 at a distance of 17km from the site.…”

“…In case of unavailability of vertical seismic motion data, two-thirds of horizontal motion may be considered (Anbazhagan et al, 2013), and therefore the peak horizontal and vertical acceleration at bedrock level is 0.3g and 0.2 g, respectively. The peak horizontal and vertical accelerations are calculated accordingly as 0.15g and 0.10g, respectively, corresponding to operating basis earthquakes (OBE) at bedrock level.…”

Bangladesh lies in a tectonically active zone. Earlier geological studies show that Bangladesh and its adjoining areas are exposed to a threat of severe earthquakes. Earthquakes may have disastrous consequences for a densely populated country. This dictates the need for a detailed analysis of the situation prior to the construction of nuclear power plant as required by the IAEA standards. This study reveals the correlation between seismic acceleration and potential damage. Procedures are presented for investigating the seismic hazard within the future NPP construction area. It has been shown that the obtained values of the earthquake’s peak ground acceleration are at the level below the design basis earthquake (DBE) level and will not lead to nuclear power plant malfunctions. For the most severe among the recorded and closely located earthquake centers (Madhupur) the intensity of seismic impacts on the nuclear power plant site does not exceed eight points on the MSK-64 scale. The existing predictions as to the possibility of a super-earthquake with magnitude in excess of nine points on the Richter scale to take place on the territory of the country indicate the necessity to develop an additional efficient seismic diagnostics system and to switch nuclear power plants in good time to passive heat removal mode as stipulated by the WWER 3+ design. A conclusion is made that accounting for the predicted seismic impacts in excess of the historically recorded levels should be achieved by the establishment of an additional efficient seismic diagnostics system and by timely switching the nuclear power plants to passive heat removal mode with reliable isolation of the reactor core and spent nuclear fuel pools.
