The test was terminated at 0500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br />, due to a malfunction in number two turbine control valve. The plant returned to full power at 0952 hours0.011 days <br />0.264 hours <br />0.00157 weeks <br />3.62236e-4 months <br />.

After maintenance, the No. 2 control valve worked properly and the test was completed. The No. 2 control valve was subsequently cycled several times and responded properly. The unit started a load increase at 1620 hours0.0188 days <br />0.45 hours <br />0.00268 weeks <br />6.1641e-4 months <br /> and reached full power at 2010 hours0.0233 days <br />0.558 hours <br />0.00332 weeks <br />7.64805e-4 months <br />.
