SUMMARY

OF OPERATING EXPERIENCE AND MAJOR SAFETY RELATED MAISTERXNft ,

The reactor remained shutdown the entire month of December, 1990, following Public Service Company of Colorado's decision to end nuclear operation ct Fort St. Vrain.

Preparatio 3 for shipping spent fuel are proceeding.

On December 31, 1990, Public Service Company of Colorado was informed by the Nuclear Regulatory Commission that the Defueling Emergency Response Plan (DERP) was approved as submitted. The existing Radiological Emergency Response Plan (RERP) will remain in effect until DERP procedures and training are fully implemented.
