Hazama Ando Corporation (Ad-hzm) General Contractors, Architects & Engineers marks more than 110 years of growth as one of Japan’s leading companies. Ad-hzm’s role in the construction of large-scale civil and public works helps to improve the total infrastructure of many countries. The company also has been engaged in designing and construction of nuclear power plants since 1960’s.
Tsukuba technical research institute of Ad-hzm established in 1992 continuously produces new architects and engineering technologies. The outputs contribute to the progress and safety of nuclear industries.
High-performance large triaxial shaking tables are used for seismic verification testing of nuclear power plant facilities and equipment. The large triaxial shaking table, which was renovated in August 2024, has improved vibration performance to take into account past large-amplitude earthquake motions and long-period, long-duration earthquake motions. The table size is 5m x 5m, and its vibration performance is a maximum acceleration of ±3G (when loaded with a 20-ton load), a maximum velocity of ±200cm/s, and a maximum displacement of ±60cm horizontally and ±30cm vertically.
Ad-hzm researches radiation protection systems for facilities such as hospitals, and is developing new materials and rational systems.
Ad-hzm is contributing to the safety disposal of radioactive waste. Concerning design and construction of artificial barrier and bentonite buffer material, laboratory experiments, monitoring and total consultants are available.
