Subj ect: Oconee Nuclear Station, Unit 3 Docket No. 50-287
Dear Sir:
A re/iew of the operational limit curves submitted by my letter of December 22, 1980 has shown that two of the coordinates on Figure 3.5.2-3C1 were incorrectly labeled. This figure shows the operational power imbalance envelope for 0 to 50 EFPD. The coordinates which are in error were submitted as (-28, 92) and
(-18, 102), but should be labeled respectively, (-28.5, 92) and (-18.6, 102).
The Staff was informed of this error via telephone in early January, 1981.
However, the figure was still in error when issued by Amendments 93/93/90 to the Oconee Facility Operating License on February 10, 1981.
Attached is a copy of the corrected Figure 3.5.2-3C1.
Duke Power Company re-quests that the Staff issue this figure as a correction to Oconce Amendments 93/93/90. As this request concerns a correction to a licensing amendment for which licensing fees have been previously paid, no additional fees are en-closed.
l Ve truly yours,
,Y W LD U-William O. Parker, Jr.
