The Low-Level Radioactive Waste Storage Site was built for the storage of whole low-level radioactive waste (LLW) in Taiwan. Until February 1996, the low-level radioactive waste was collected by the Low-Level Radioactive Waste Storage Site from May 1982. Previously, Office of Radioactive Waste Management (now Fuel Cycle and Materials Administration) of Atomic Energy Council (hereinafter referred to as the AEC), Executive Yuan was in charge of the Low-Level Radioactive Waste Storage Site. However, It was taken over by Taiwan Power Company in July 1990 and referred to "Low-Level Radioactive Waste Storage Site" from "Lanyu Storage Site" on June 19, 2018.

The Low-Level Radioactive Waste Storage Site is filled with LLW in 1996, almost 97,672 drums (55 US gal). Among them, 86,380 drums came from nuclear power plants, and the remaining 11,292 drums came from various sectors, such as medical, agricultural, industrial, and academic fields. Due to increasing the operational safety, the entire LLW drums in the Low-Level Radioactive Waste Storage Site are examined and repacked, thereby increasing the number of storage drums (total 100,277 drums).

Note: The decrease of LLW drums at the No. 1 Nuclear Power Plant and No. 2 Nuclear Power Plant is due to some of the waste drums being crushed and solidified, and then were classified as examination and repacking drums at Low-Level Radioactive Waste Storage Site.
