(EDT) that the supports and anchorage for four additional 600 volt switchgear sections in both Unit I and Unit 2 do not meet seismic requirements.
The equipment was declared inoperable and Technical Specifications require shut-down within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
