SUBJECT:

PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 TRANSMITTAL OF DRAFT SAFETY EVALUATION FOR PROPOSED AMENDMENT RE: USE OF NEUTRON ABSORBING INSERTS IN SPENT FUEL POOL STORAGE RACKS (TAC NOS. ME7538 AND ME7539)

Dear Mr. Pacilio:

By application dated November 3, 2011, as supplemented by letters dated December 22, 2011, April 4, 2012, May 17, 2012, June 21,2012, August 15, 2012, November 13, 2012, and April 18, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession Nos.

ML113081441, ML113570208, ML12096A052, ML12139A404, ML12188A094, ML12228A474, IVIL12319A230, and ML131090073, respectively), Exelon Generation Company, LLC (Exelon, the licensee), requested changes to the Technical Specifications and Facility Operating Licenses for Peach Bottom Atomic Power Station, Units 2 and 3. The proposed license amendment would allow the use of neutron absorbing inserts in the spent fuel pool (SFP) storage racks for the purpose of criticality control in the SFPs.

Enclosed is the draft safety evaluation (SE) that the Nuclear Regulatory Commission (NRC) staff has prepared to support the proposed license amendment. The draft SE is being withheld from public disclosure at this time because it contains proprietary information pursuant to Section 2.390 of Title 10 of the Code of Federal Regulations (10 CFR). Proprietary information is identified by text enclosed within double brackets as shown here ((

)).

The NRC staff requests that Exelon provide comments regarding the proprietary content in the draft SE within 5 business days from the date of this letter. The response timeframe was discussed with Mr. Tom Loomis of your staff on May 3, 2013.

Since the NRC review is not yet complete, this letter and the enclosure do not conveyor represent an NRC staff position regarding the licensee's request. Should the amendment be approved, the NRC staff will issue a publicly available, nonproprietary version of the SE.

Enclosure transmitted herewith contains sensitive unclassified information.

When separated from enclosure, this transmittal document is decontrolled.
