On September 26, 1983, a breach was found in a passive fire barrier in the west wall of the 4 KV vital switchgear room. The fire barrier was penetrated for the purpose of running cables in the cable tray which penetrates the wall by contractors in early spring this year. The problem was rectified the same day. A Significant Operating Event will be written on this incident.

On September 20, 1983, the annual NRC-required Emergency Plan drill was conducted and lasted approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />.
