Development in the IAEA Containment and Surveillance Scheme at LWRs in Korea

This new partnership utilizes the remote monitoring (RM) on the containment and surveillance system (C/S) at light water reactors (LWR) in Korea where the data are transferred to the IAEA and KINAC (the predecessor of TCNC, KAERI), simultaneously. This program is based on a joint-use equipment and data sharing plan. The RM based C/S system was being implemented through a few modifications for seven years after the integrated safeguards (IS) started. The enhanced co-operation was replaced by new arrangement. The IAEA proposed the use of unannounced inspections (UI) along with roaming camera concept to install temporary surveillance cameras instead of permanent installation at LWRs in 2013. New C/S system with no use of RM has been applied from 2015 to the present. Since Korea and the IAEA launched an enhanced cooperation on Safeguards implementation at LWRs in 2001, the IAEA containment and surveillance approach proceeded to three stages; 1) C/S under traditional Safeguards. 2) C/S under Integrated Safeguards. Under the SLA Update, UI in conjunction with a roaming camera concept (ISP- 1) started in 2016. Only temporary roaming cameras with EOSS seals are used. Accordingly, existing permanent surveillance with RMS was ended.
