This paper describes the lessons learned of the maintenance technologies, which has been and will be developed by using the high temperature engineering test reactor (HTTR), which should be expected to apply to the future HTGRs. The maintenance technologies for the reactor system, which have been developed by using HTTR, are categorized as followings; (1) Establishment of the maintenance technologies specific to the HTGRs. (2) Development of the maintenance technologies for the future HTGRs. (3) Efficient maintenance works for the general equipment.
