Site
(1/3)
 Easy Access through International Airport, Port, Highway
11
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.
