emotional and artistic experiences. An interactive theatre was also built onsite
(Fig. 6.32). Near the reactor hall is the restaurant.

6.5.12 Korea Research Reactor No.1 (Seong et al., 2017)

The radiation dose of the Korea Research Reactor-1 (KRR-1), which had been
decontaminated and decommissioned following shut down in 1995, was evaluated
in 2017 to assess the safety of reusing the building as a memorial hall. The KRR-1
holds symbolic significance as the first reactor in Korea and is a registered cultural
property. Exposure scenarios for visitors and the building keepers were evaluated,
and compliance with the dose criteria for unrestricted release of the building was con-
firmed. It is noteworthy that the decision to establish a memorial at KRR-1 was based
on a survey of 800 persons: with a two-thirds majority the memorial option was
selected over entombment or unrestricted release. On the technical side, the following
details were provided in Lee et al. (2010):

l All facilities inside the KRR-1 biological shield will be retained
l All external facilities (ventilation, cooling system, etc.) will be dismantled
l New equipment will be installed for cleaning the pool water
