Abstract EN
The Fukushima Dai-ichi nuclear power plant accident shows that an extreme natural disaster can prevent the proper restoration of electric power for several days, so-called extended SBO.
In Korea, the government and industry performed comprehensive special safety inspections on all domestic nuclear power plants against beyond design bases external events.
One of the safety improvement action items related to the extended SBO is installation of external water injection provision and equipment to RCS and SG.
In this paper, the extended SBO coping capability of APR1400 is examined using MAAP4 to assess the effectiveness of the external water injection strategy.
Results show that an external injection into SG is applicable to mitigate an extended SBO scenario.
However, an external injection into RCS is only effective when RCS depressurization capacity is sufficiently provided in case of high pressure scenarios.
Based on the above results, the technical basis of external injection strategy will be reflected on development of revised severe accident management guideline.
