UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. Bryan C. Hanson Senior Vice President Exelon Generation Company, LLC President and Chief Nuclear Officer Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555 November 30, 2018

SUBJECT:

CALVERT CLIFFS NUCLEAR POWER PLANT, UNITS 1 AND 2 -CORRECTION TO AMENDMENT NOS. 326 AND 304 RE: ADD RISK-INFORMED COMPLETION TIME PROGRAM (EPID L-2016-LLA-0001)

Dear Mr. Hanson:

By letter dated October 30, 2018, the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 326 to Renewed Facility Operating License No. DPR-53 and Amendment No. 304 to Renewed Facility Operating License No. DPR-69 for the Calvert Cliffs Nuclear Power Plant (Calvert Cliffs), Units 1 and 2, respectively.

The amendments consisted of changes to the Technical Specifications (TSs) in response to your application dated February 25, 2016, as supplemented by letters dated April 3, 2017, and January 11, January 18, June 21, and August 27, 2018. The amendments revised the Calvert Cliffs, Units 1 and 2, TSs related to completion times for required actions to provide the option to calculate longer risk-informed completion times. The amendments also added a new program, the "Risk-Informed Completion Time Program," to TS Section 5.5, "Programs and Manuals." Subsequent to issuance of the amendments, the NRC staff was notified by Exelon Generation Company, LLC of (1) two errors that had been identified in the Safety Evaluation (SE) and (2) an indication that in several of the updated TS pages, change bars were not placed consistent with prior Calvert Cliffs TS change bar usage. Safety Evaluation Corrections:

1. On page 7, "TS 3.5.2, Condition C -One or more containment air locks inoperable for reasons other than Conditions A or 8, Required Action C.3," TS 3.5.2 should be corrected to TS 3.6.2. 2. On page 8, "TS 3.8.9, Condition A -One or more AC electrical power distribution subsystems inoperable," is missing the "Required Action A.1," at the end of the sentence.

The NRC staff has determined that these errors were inadvertently made in the SE and are entirely editorial in nature. These corrections do not change any of the conclusions in the SE associated with the issuance of Amendment Nos. 326 and 304 and do not affect the associated notice to the public. Enclosed are two replacement SE pages containing a marginal line indicating the area of change.

B. Hanson TS Page Corrections:

Change bar locations have been corrected for several TS pages to be consistent with prior Calvert Cliffs TS change bar usage. Enclosure 2 contains the corrected TS pages with change bars removed/relocated as appropriate for the following pages: 3.3.6-3 3.3.6-4 3.6.2-6 3.6.6-2 3.7.3-4 3.7.3-5 3.7.3-6 3.7.6-3 3.7.7-3 3.8.1-10 3.8.1-11 3.8.1-12 3.8.1-13 3.8.1-14 3.8.1-15 3.8.1-16 3.8.1-17 3.8.1-18 We apologize for any inconvenience caused.
