Classification of Radioactive Waste

Radioactive waste is classified into the low and intermediate level wastes and the high level wastes depending on their levels of radiation. Moreover, they are also classified into gas, liquid or solid depending on types of generation.

Low and Intermediate Level Radioactive Waste

Low and Intermediate Level Radioactive Waste

90% of generation rate :
Working clothes, boots, rags and replaced parts used in the controlled area of nuclear power plant are temporarily stored at a nuclear power plant site 10% of generation rate :
Reagent bottles, syringes and tubes occurring from industrial research institutions or hospitals using radioisotopes are temporarily stored at the RI waste storage of KORAD

High level Radioactive Waste

High Level Radioactive Waste

The spent nuclear fuels for nuclear power generation are temporarily stored in nuclear power stations until the relevant national decision is made (recycling or permanent disposal).
At present, Korea has kept the “Wait & See” policy to determine the management policy of spent nuclear fuels since there is uncertainty in reprocessing/disposal, technology development level and international diplomatic environments.

Low and Intermediate Level Radioactive Waste

Low and Intermediate Level Radioactive Waste(filters, boots, toilet paper, reagent bottles, syringes, working clothes, replaced parts)

Radioactive Waste Management System

The Management Policy is determined based on social consensus. Nuclear Power Plant(Spent Nuclear Fuels-Storage in Site, Management Policy, Interim Storage Faclility, Reprocessing, Recycle/ Low and Intermediate Level Wastes-Storage in Site) Radiosotope(Radiosotope Wastes-Storage Management, LILW Disposal Facility, Sealed Package, Permament Disposal)
