UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 July 3,2012 Mr. Michael J. Pacilio President and Chief Nuclear Officer Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555

SUBJECT:

OYSTER CREEK NUCLEAR GENERATING STATION-CORRECTION TO RELIEF FROM THE REQUIREMENTS OF THE ASME CODE, RELIEF REQUEST NO. PR-01 FOR FIFTH INSERVICE TESTING INTERVAL (TAC NO. ME7616)

Dear Mr. Pacilio:

By letter dated November 17, 2011 (Agencywide Documents and Access Management System (ADAMS) Accession No. ML113250626), Exelon Nuclear submitted Relief Request (RR) PR-01 for Oyster Creek Nuclear Generating Station (OCNGS) during the fifth Inservice Testing (1ST) interval, requesting the use of an alternative to certain requirements of the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code).

By letter dated June 21, 2012 (ADAMS Accession No. ML120050329), the U.S. Nuclear Regulatory Commission (NRC) staff authorized the alternative described in RR PR-01 for the fifth 1ST interval at OCNGS, which will begin on October 14,2012, and ends on October 13, 2022.

Subsequently, it was discovered that the NRC staff made a typographical error in the third sentence of the second paragraph on page 5 of the safety evaluation (SE). The sentence currently reads:

However, the NRC staff has reviewed OMN-18, and currently has no concerns with its usage, providing that the high values of the Group A test "Required Action Range" for flow (Q) and differential pressure (~P) are greater than 106%

of the respective reference values.

The sentence should be corrected in the SE to read the following:

However, the NRC staff has reviewed OMN-18, and currently has no concerns with its usage, providing that the high values of the Group A test "Required Action Range" for flow (Q) and differential pressure (~P) are less than 106% of the respective reference values.

M. Pacilio -2 If you have any questions regarding this matter, please contact me at (301) 415-3100 or bye-mail at John.Lamb@nrc.gov.

Sincerety,
