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).
