These Regulations are enacted pursuant to Article 21 of the Nuclear Materials and Radioactive Waste Management Act.

The terms used in these Regulations are defined as follows:
1.Solidifying & Packing: refers to transforming the waste into stable solidified waste and encapsulating them into the containers, so as to making the operation of waste packages suitable for loading, unloading, transportation, storage, and disposal.
2.Leaching index: refers to the index of radioactive nuclides’ leaching from the solidified waste.
3.Final disposal facilities of low level waste (hereinafter shortened as “low level disposal facilities”): refer to the lands, buildings, structures, and equipments used to dispose the low level waste.
4.Multiple barrier: refers to the combination of solidified waste, containers, buffering and backfill materials, engineering structures, and stratums as well as natural barriers used by the radioactive waste disposal facilities of to delay the leaching, leakage, and migration of the radioactive nuclides.
5.Disposal control area: refers to the surface and underground space within the range of the disposal facilities of radioactive waste. Permanent monuments or markers shall be set to indicate the borderlines of the disposal control area.
6.High-Integrity Container: refers to the low level waste container which can maintain its structural integrity and prevent the radionuclide release in at least three hundred years.
