Press Release (Aug 31,2009)
Performing a Series of Functional Tests for the Entire Plant of the Kashiwazaki-Kariwa Nuclear Power Station Unit No.6 after the Niigata-Chuetsu-Oki Earthquake (Starting generation)
The Kashiwazaki-Kariwa Nuclear Power Station Unit No.6 (ABWR: 1,356MW) had been shut 
down since the Niigata-Chuetsu-Oki Earthquake occurred on July 16, 2007. On August 25, 
2009, we started a series of functional tests for the entire plant, and are performing 
the pre-planned tests. 

After activating a main turbine generator, we have performed various pre-planned tests 
such as temporarily connecting the main generator to the transmission network, and 
confirmed these results to be satisfactory by 9:00 a.m. of August 31.

Based on these results of the tests, once we isolated the main generator from the 
transmission network and verified the function of protective devices of the main turbine 
generator. Subsequently, we connected the main generator to the transmission network 
again, we re-started the generation at 1:39 p.m. of August 31.

Currently, we are raising generating power to approx. 20% of the rated output. After 
reaching approx. 20% of the rated output, we will keep it and perform the pre-planned 
tests carefully. 

We will disclose test evaluation results accordingly.
