POST OFFICE BOX 790 i HARTSVILLE, SOUTH CAROLINA 29550 l JANI 51987 I Robinson File No: 13510C Serial: RNPD/87-75 100FR50.73 United States Nuclear Regulatory Commission Attn: Document Control Desk Washington, D. C. 20555 H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 DOCKET NO. 50-261 LICENSE NO. DPR-23 LICENSE EVENT REPORT 86-012, REVISION 1

Dear Sir:

In accordance with 10CFR50.73, Licensee Event Report System, the enclosed  !

Licensee Event Report (LER) is submitted. The original LER of September 24, 1986, described an automatic Pressurizer low pressure reactor trip on August 25, 1986.

This submittal provides certain changes to information in the LER. This Revision 1 should replace all existing copies of the original report.

Revision 1 revises the level of reactor power from which Unit 2 tripped.

Originally, 42% power was shown. Subsequent reanalysis of operating data indicates that the trip occurred from about 13% power. In addition, the Operating Mode block has been marked "N" as recommended by NUREC-1022.

This report is in accordance with the format set forth in NUREC-1022 of September, 1983. The revised information has been barred for your convenience.

Very truly yours, (ds- -
