Source term estimation of atmospheric release due to the Fukushima Dai-ichi Nuclear Power Plant accident by atmospheric and oceanic dispersion simulations

Abstract: The source term of the atmospheric release of 131 I and 137 Cs due to the Fukushima Dai-ichi Nuclear Power Plant accident estimated by previous studies was validated and refined by coupling atmospheric and oceanic dispersion simulations with observed 134 Cs in seawater collected from the Pacific Ocean. By assuming the same release rate for 134 Cs and 137 Cs, the sea surface concentration of 134 Cs was calculated using the previously estimated source term and was compared with measurement data. The release rate… Show more

“…The eastward speed of the radioactive plume was estimated to be 8 cm s −1 . Moreover, atmospheric deposition of radioactive Cs and 131 I south of the KE near the east coast of Japan was strongly indicated by numerical simulations (Kawamura et al 2011 ;Kobayashi et al 2013 ). Thus, the highly radioactive Cs area observed in the central North Pacifi c in July 2011 and south of the KE near the east coast of Japan may have originated from atmospheric deposition.…”

“…In the present study, the radioactive Cs detected in the southern region was thought to contain the atmospheric fallout from the FNPP to the sea surface south of the KE during mid-March and early April 2011 (Sect. 2.3 ; Chino et al 2011 ;Rypina et al 2013 ;Honda et al 2012 ;Kobayashi et al 2013 ).…”

“…Most efforts on the investigation of the contamination in the ocean have centred on the radiocaesium isotopes 134 Cs (T½ = 2.06 y) and 137 Cs (T½ = 30.2 y), of which between 5 to 11.7 PBq would have been deposited onto the regional ocean (Estournel et al, 2012;Kawamura et al, 2011;Kobayashi et al, 2013). The direct liquid discharges to sea were estimated to be about 2.8-5.9 PBq (Miyazawa et al, 2013;Tsumune et al, 2012;Tsumune et al, 2013), although other authors produced larger figures, ranging from 13.5 to 27 PBq (Bailly du Bois et al, 2012;Charette et al, 2013;Rypina et al, 2013).…”

“…The total quantity of 131 I and 137 Cs released into the atmosphere between 12 March 2011 and 1 May 2011 was estimated to be approximately 2.0 × 10 17 Bq and 1.3 × 10 16 Bq, respectively. Furthermore, the quantities of 131 I and 137 Cs deposited on the ocean surface from the atmosphere were estimated as 9.9 × 10 16 Bq and 7.6 × 10 15 Bq, respectively (Kobayashi et al 2013 ).…”
