4 OPERATIONS NARRATIVE Cooper Nuclear Station October 1982 During normal power operation on October 5,1982, 'a failure in the turbine control valve system caused the turbine control valves to close initiating a reactor scram. The electrical insulation for the control cable for the turbine control valves was found to have deteriorated and shorted out from the heat and radiation of a nearby main steam line.

The damaged cable was replaced and the plant returned to operation. The plant operated the remainder of the month with no other power reductions or outages.
