The Kashiwazaki-Kariwa Nuclear Power Station Unit No.7 (ABWR: 1,356MW) had been shut down since
the Niigata-Chuetsu-Oki Earthquake occurred on July 16, 2007. On May 8, 2009, we started a
series of functional tests for the entire plant, and are performing pre-planned tests.
The unit began generating power on May 19, and is keeping constant operation at rated thermal
output. We have performed pre-planned tests, and confirmed operating status to be satisfactory
by 1:30 p.m. today.
As for the steam leakage from the turbine driven reactor feed water pump (A) discharge valve,
we responded by further fastening the upper cover of the valve.
Based on the results of the tests, we will continue operating at constant rated thermal output
and will perform the pre-planned tests carefully.
We will disclose test evaluation results accordingly.
