ENCLOSURE Meeting Summary Licensee: Duke Power Company Facility: Oconee Nuclear Station Docket Nos.: 50-269, 50-270, 50-287

Subject:

Emergency Plan Deficiencies On L ember 5,1986, licensee representatives met with personnel from the NRC Region II Office in Atlanta, Georgia. The licensee requested the meeting to discuss the NRC plan review findings regarding the changes in emergency action levels (EALs) incorporated in Revision 85-02 to the Oconee Nuclear Station Emergency Plan. The attendance list for the meeting is enclosed as Attachment A to this summary.

l The licensee presented a response to the NRC letters dated March 31, 1986, and October 29, 1986, which identified several inconsistencies between the revised EAls and Appendix 1 of NUREG-0654. The referenced inconsistencies involved a decrease in the conservatism of the EALs relating to evacuation of the Control Room and loss of most or all annunciators.

Licensee representatives gave a detailed presentation (outlined in Attachment 8 to this summary) of the rationale for the changes which had been identified as Emergency Plan deficiencies. Staff review following the meeting determined that the licensee's proposed modifications to correct the deficiencies in question would, with minor changes, meet the intent of NRC guidance criteria. A licensee representative (C. C. Jennings) was telephonically informed of this determination on December 5, 1986.

Investigation showed that most of the CR statalarm panels had lost power.

CR personnel had indications to show that the unit was remaining )

0532 Power restored to KX inverter.

All statalarm panels operable.
