UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April15, 2014 Mr. Michael J. Pacilio President and Chief Nuclear Officer Exelon Generation Company, LLC 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
PEACH BOTTOM ATOMIC POWER STATION, UNIT 3- RELAXATION OF CERTAIN SCHEDULE REQUIREMENTS FOR ORDER EA-12-049 "ISSUANCE OF ORDER TO MODIFY LICENSES WITH REGARD TO REQUIREMENTS FOR MITIGATION STRATEGIES FOR BEYOND DESIGN BASIS EXTERNAL EVENTS"
Dear Mr. Pacilio:
By letter dated March 12, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML12054A735), the U.S. Nuclear Regulatory Commission (NRC) ordered Exelon Generation Company, LLC (Exelon or the licensee) to take certain actions at Peach Bottom Atomic Power Station (Peach Bottom), Units 2 and 3, associated with the Fukushima Near-Term Task Force Recommendations. Order EA-12-049 directed that actions be taken by licensees to develop and implement strategies to maintain or restore core cooling, reactor coolant system inventory, containment cooling, and spent fuel pool cooling capabilities during beyond design basis external events (BDBEEs). By letter dated March 12, 2012 (ADAMS Accession No. ML12054A694), the NRC ordered Exelon to install a reliable hardened containment vent system at Peach Bottom, Units 2 and 3, via Order EA-12-050. By letter dated June 6, 2013 (ADAMS Accession No. ML13143A321), the NRC superseded the requirements of Order EA-12-050, with Order EA-13-1 09, which requires the installation of reliable hardened containment vents capable of operation under severe accident conditions. The compliance date requirements of Order EA-13-1 09, Phase I (wetwell vent), extend beyond those of Order EA 049 for Peach Bottom, Units 2 and 3.
Section IV of Order EA-12-049 states that licensees proposing to deviate from requirements of the order may request that the Director, Office of Nuclear Reactor Regulation, relax or rescind certain requirements. By letter dated February 26, 2014 (ADAMS Accession No. ML14057A552), the licensee requested schedule relaxation from the final compliance date of Order EA-12-049, for Peach Bottom, Unit 3 only. Specifically, the licensee requested an extension of one refueling cycle for Peach Bottom, Unit 3, to complete full implementation of the hardened severe accident capable containment wetwell vent. The extension request was proposed because the installation of a containment wetwell vent that meets the requirements of Order EA-13-109, Phase I, will take additional time to complete for Unit 3, as compared to the compliance date associated with Order EA-12-049.
To allow the time to design and install the severe accident capable hardened containment wetwell vent, and integrate it into the mitigating strategies required for Order EA-12-049, the licensee requests to relax the Order EA-12-049 full implementation date for Peach Bottom,
M. Pacilio Unit 3, from the completion of the fall 2015 refueling outage to the completion of the fall 2017 refueling outage.
In light of the facts presented in the licensee's letter dated February 26, 2014, the NRC staff has determined that the licensee has presented good cause for a relaxation of the order implementation dates. The licensee proposes the equipment and modifications required to implement the mitigating strategies required by Order EA-12-049 will be completed and available for use in accordance with the original implementation schedule requirements, except for the primary containment venting strategy. Until the full containment wetwell venting capability required by Order EA-13-109 is implemented, Exelon will maintain a containment venting strategy in accordance with existing emergency operating procedures at Peach Bottom, Unit 3. By completing the specified plant configuration changes (other than the severe accident capable containment wetwell vent), and maintaining the ability to vent containment in accordance with existing procedures, a portion of the desired increase in capability to respond to a BDBEE will be realized within the timeframe specified in Order EA-12-049. The requested extension allows the licensee sufficient time to install the enhanced containment wetwell vent capability necessary for full Order EA-12-049 compliance within an appropriate amount of time, consistent with the requirements of Order EA-13-1 09. The NRC staff also considered that, following the accident at Fukushima Dai-ichi, the NRC concluded that a sequence of events such as the Fukushima Dai-ichi accident is unlikely to occur in the United States based on the current regulatory requirements and existing plant capabilities. The NRC staff therefore approves the relaxation of the order implementation date for Peach Bottom, Unit 3.
Accordingly, based upon the authority granted to the Director, Office of Nuclear Reactor Regulation, the requirement of the order for full implementation is relaxed until the completion of the fall 2017 refueling outage for Peach Bottom, Unit 3, to allow the licensee sufficient time to implement a severe accident capable hardened containment wetwell vent at that unit. The licensee did not request relaxation of the requirement for full order implementation for Peach Bottom, Unit 2, so the requirement for full implementation of Order EA-12-049 by the completion of the Unit 2 fall 2016 refueling outage is unchanged.
If you have any questions, please contact Randy Hall at 301-415-4032.
Sincerely, Eric J. eeds, Director Office of Nuclear ReaCtor Regulation Docket No. 50-278 cc: Listserv
