A comparison study between the present air cleaning unit of main control room of AP1000 and its replacement design
The inleakage of the radioactivity caused by ingress/egress could reduce the habitability of the main control room for the operators under the accident conditions. This study used the concentration-decay method to measure the air inleakage caused by ingress/egress, and based on this point, theoretical calculations of the radioactivity in the vestibule and the main control room were conducted to clarify the air cleaning effect. The results showed that: The measured air inleakage induced by each ingress/egress ranged from 0.273 m3 to 1.818 m3 at different opening speed and degree of the door. Compared with the present internal recycle air cleaning unit of main control room of AP1000, we recommended a design which can remove the radioactivity incurred from ingress/egress more effectively and rapidly. Therefore, to reduce the radiation risk of operators in main control room at designed basic accidents, the implementation of replacement is proposed as soon as possible.
期刊介绍：
Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
