JRR-3 has not been in operation since the end of 2010, because of the new regulatory requirement established after the large earthquake and the concomitant accident at the Fukushima Dai-ichi Nuclear Power plant. Japan Atomic Energy Agency (JAEA) submitted an application document for the restart of JRR-3 in 2014 which is still under the review. A recent official announcement by JAEA tells an expected restart of JRR-3 in the beginning of 2018. In parallel to this reviewing process, there is ongoing joint activities between JAEA and university groups for the recovery. This includes reorganization of experimental hall which results in securement of sample environment area. We are also trying to restart sample environment equipments safely after a long sleeping. We will show our strong efforts to realize "Science with Safety" in JRR-3. In addition, developments on sample environment have been made without neutron.
