Article 2
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.

Article 6
The homogeneous solidifying waste shall meet the following provisions:
1. Use the single-axis compression strength method to test the mechanical strength of cement-solidified or high-temperature melting waste which shall be more than 15kg/cm2; the mechanical strength of bituminous waste shall be measured by penetration test, and the value of penetration shall be less than 100.
2. The leaching index shall be greater than 6.
3. After the process of water resistance test, the provisions of Subparagraph 1 shall be observed.
4. After the process of weather resistance test, the provisions of Subparagraph 1 shall be observed.
5. After the process of radiation resistance test, the provisions of Subparagraphs 1 shall be observed.
6. After the process of bacteria-resistance test, the provisions of Subparagraph 1 shall be observed.
The items, methods, and standards of the tests referred to in the Subparagraphs 1, 3 of Article 5 and above Subparagraphs are shown in the Annexed Table 3.
