Construction method for Kashiwazaki-Kariwa Nuclear Power Station Unit 5

The Tokyo Electric Power Co., Inc. Kashiwazaki-Kariwa Nuclear Power Station Unit 5, which is a BWR plant with 1,100MW electric output, started construction in October, 1983 and began public operation on April 10, 1990. This is the first plant which fully applied the results of The Second Improvement and Standardization Program for Light Water Reactors and also the latest facility of which reliability has been much more improved using the technologies developed everywhere. Especially, by introducing the large-scale crawler crane to the construction site first in Japan, the prefabrication methods were widely applied and new methods were established to overcome the reduction of work efficiency caused by the winter season weather condition, thus reducing the construction schedule and improving safety of site work.
