The proposed amendment would revise the Technical Specifications and Renewed Facility Operating Licenses to allow operation in the expanded Maximum Extended Load Line Limit Analysis Plus (MELLLA+) domain.
Enclosed is the draft safety evaluation (SE) that the U.S. Nuclear Regulatory Commission (NRG) staff has prepared to support the proposed MELLLA+ license amendment. The draft SE has also been provided to the Advisory Committee on Reactor Safeguards (ACRS) in preparation for the upcoming meetings which are currently scheduled as follows:
ACRS Subcommittee Meeting on December 2, 2015, in Rockville, Maryland; and ACRS Full Committee Meeting on February 11, 2016, in Rockville, Maryland.
The draft SE is being withheld from public disclosure at this time, because it contains proprietary information pursuant to Title 1 O of the Code of Federal Regulations Section 2.390. The NRG The enclosure transmitted herewith contains sensitive unclassified information.
When separated from the enclosure, this document is decontrolled.
OFFICIAL USE ONLY PROPRIETARY INFORMATION
OFFICIAL USe ONLY PROPRleTARY INFORMATION staff has made some preliminary proprietary markings in the draft SE identified by underlined text (in red font) enclosed within double brackets.
The NRC staff requests that Exelon provide comments regarding the proprietary content in the draft SE within 15 business days from the date of this letter. Comments may also be provided regarding the factual accuracy of the information in the draft SE. The response timeframe was discussed with Mr. Kevin Borton of your staff on October 29, 2015.
