INTRODUCTION

As of 1986, Japan, with its hydraulic generating capacity of 35,700 MW in 1,616 locations, ranked fourth in the world following the United States, the Soviet Union and Canada. The hydraulic power generation capacity of Japan occupies approximately 20% of the total power generating facilities of 173,800 MW, which includes thermal power plants and nuclear power plants. Therefore, it plays an important role as a precious domestic energy supply source. In addition, more power plant construction projects entailing around a large-capacity and high head pumped storage power plant have been making progress in recent years. Seventy-eight power plants capable of generating a total power of 9,580 MW have been completed since 1976.

In connection with the construction of these pumped storage power plants, a variety of new technologies have been introduced in the field of steel penstocks and gates in order to cope with the technical difficulties stemming from the large capacity and the high head.

In order to publicize Japan's technical standards for hydraulic gates and penstocks to the whole world, the Hydraulic Gate and Penstock Association published "Technical Standards for Gates and Penstocks" (English version) in 1971. On the basis of the technical results as mentioned above, the Technical Standards for Gates and Penstocks (Japanese version) was revised in 1981 and therefore "Technical Standards for Gates and Penstocks" (English version) has also been revised.

The Hydraulic Gate and Penstock Association was established in 1949 as a foundation juridical person with the participation as regular members of the hydraulic gates and penstocks manufacturers and the Ministry of International Trade and Industry (MITI), the Construction Ministry, the Ministry of Agriculture, Forestry and Fisheries, the Water Resources Development Corporation, the Japan Power Development Corporation, the Electric Power Development Co., Ltd. and major power companies, experts as supporters, members. Since its founding, the Association has been making contributions to advancement of the hydraulic gates and penstocks industries with the mutual cooperation of the government agencies and the commercial enterprises. Therefore, the Technical Standards for Gates and Penstocks established by this association are extremely authoritative in Japan.
