In order to achieve carbon neutrality (CN) and energy security for Japan, Toshiba Energy Systems & Solutions Corporation (Toshiba) aims to supply an improved ABWR that can be constructed and operated in early 2030s.
In particular, the installation of the Specific Major Accident Response Facilities (SARF) is now mandatory for existing reactors as a countermeasure against APC (Airplane Crash), and the situation is very severe in which plant safety and economic competitiveness conflict with each other. Considering the situation, Toshiba has developed design and evaluation technologies for power plant structures that can achieve a high degree of compatibility between safety and economy.
The ability to precisely simulate the process from impact to structural failure will help increase confidence in the effectiveness of APC protective structures and improve the accountability of permitting.
Therefore, the analysis method was verified through experimental research and analytical research assuming APC, and by applying the verified method to structures such as the reactor building, it was confirmed APC protection is functioning effectively.
The design of robust reactor buildings based on this technology will prevent the occurrence of severe accidents caused by APC, thereby improving safety. The design of a robust reactor building using this technology will improve safety by preventing the occurrence of severe accidents caused by APC, and will also improve economic efficiency by eliminating the need for specific facilities to deal with severe accidents.
