Site (1/3)

Easy Access through International Airport, Port, Highway

12

Site (2/3)

The site was selected through competitions among 9 local governments that have expressed their wishes to host the KJRR.

The site is very close to Busan which is the second largest city in Korea and has an international airport and a harbor which provide good accessibility as well as easy transportation of products.

The site is very close to several existing NPPs in operation. Thus, it is expected that there is no difficulty in the site characteristics including PA.
