Nuclear Regulatory Commission.


Draft generic letter; public meeting and request for comment.


The U.S. Nuclear Regulatory Commission (NRC) is seeking public comment on a draft generic letter to request information from licensees to address the treatment of natural phenomena hazards in fuel cycle facilities. The NRC has determined that facility-specific information is necessary to confirm that fuel cycle facilities are in compliance with appropriate regulatory requirements. The NRC will use information submitted by licensees in response to the generic letter if additional regulatory action is warranted.


Submit comments by November 6, 2014. Comments received after this date will be considered if it is practical to do so, but the NRC is able to assure consideration only for comments received on or before this date.

II. Background

The NRC is issuing draft Generic Letter 2013 XX-XX: “Treatment of Natural Phenomena Hazards In Fuel Cycle Facilities” (ADAMS Accession No. ML13157A158), to request information from addressees to demonstrate if compliance is being maintained with the regulatory requirements and applicable license conditions regarding the treatment of natural phenomena events in the facilities' safety assessments; and to determine if additional NRC regulatory action is necessary to ensure that licensees are in compliance with their current licensing basis and existing NRC regulations.

On March 11, 2011, the Tohoku-Taiheiyou-Oki earthquake occurred near the east coast of Honshu, Japan. This magnitude 9.0 earthquake and the subsequent tsunami caused significant damage to at least four of the six units of the Fukushima Dai-ichi nuclear power station and, as a result, there was a loss of offsite and onsite electrical power systems.

On March 23, 2011, the Chairman of the NRC, via Tasking Memorandum—COMGBJ-11-0002, “NRC Actions Following the Events in Japan,” directed the NRC's Executive Director for Operations to establish the NRC Near-Term Task Force (NTTF) to evaluate available technical and operational information from the events in Japan following the March 11, 2011, earthquake and tsunami at the Fukushima Dai-ichi nuclear power station. The NTTF was tasked to consider lessons learned from the event and to develop recommendations to improve the regulatory systems for reactors in the United States and their applicability to licensed facilities other than power reactors.

On July 12, 2011, in light of the accident at the Fukushima Dai-ichi nuclear power plant, the NTTF presented a set of recommendations as a result of a systematic and methodical review of NRC processes and regulations applicable to nuclear power reactors in the United States (ADAMS Accession No. ML111861807). The NTTF recommendations are intended to clarify and strengthen the regulatory framework for protection against natural disasters, mitigation and emergency preparedness of nuclear power reactors in the United States.

For fuel cycle facilities, in light of the lessons learned from the accident at the Fukushima Dai-ichi nuclear power plant, the staff performed a systematic evaluation and inspection of selected fuel cycle facilities to confirm that licensees were in compliance with regulatory requirements and license conditions; and to evaluate their readiness under natural phenomena hazards (NPH) events and other licensing bases events related to NPH. The staff's assessment considered the NTTF recommendations to determine whether additional regulatory actions by the NRC are warranted.

The staff completed inspections at selected fuel facilities and the results were used to perform a systematic evaluation of the processes and regulations applicable to fuel facilities. The results of the evaluation allow the staff to conclude that the current regulatory approach and requirements of these licensees continues to serve as a basis for reasonable assurance of adequate protection of public health and safety. However, the staff identified generic issues regarding compliance with the current regulatory framework with regards to the treatment of certain natural phenomena events in the facilities (uranium conversion, enrichment and fuel fabrication) safety assessments. The NRC is issuing this draft generic letter to request information from licensees to verify that compliance is being maintained with regulatory requirements and license conditions regarding the treatment of natural phenomena events.

III. Cumulative Effects of Regulation

The NRC is considering the cumulative effects of regulation (CER) as they relate to this Generic Letter. The CER considers the challenges licensees face in addressing the implementation of new regulatory positions, programs, and requirements (e.g., rulemaking, guidance, backfits, inspections). The CER initiative stems from the total burden imposed on licensees by the NRC from simultaneous or consecutive regulatory actions that can adversely affect the licensee's capability to implement those requirements while continuing to operate or construct its facility in a safe and secure manner. The NRC proposed several rulemaking process enhancements to address CER in SECY-11-0032, “Consideration of the Cumulative Effects of Regulation in the Rulemaking Process,” dated October 11, 2011 (ADAMS Accession No. ML112840466). In SECY-12-0137, “Implementation of the Cumulative Effects of Regulation Process Changes,” dated October 5, 2012 (ADAMS Accession No. ML12223A162) built upon the recommendations in SECY-11-0032. In its Staff Requirements Memorandum to SECY-12-0137 (ADAMS Accession No. ML13071A635), the Commission directed the staff to, among other items, “continue to develop and implement outreach tools that will allow NRC to consider more completely the overall impacts of multiple rules, orders, generic communications, advisories, and other regulatory actions on licensees and their ability to focus effectively on items of greatest safety importance.”

With regard to this generic letter, the NRC requests that licensees comment about any CER challenges they may face. Specifically, the NRC requests comment on the following questions:

a. In light of any current or projected cumulative effects, does this generic letter request provide sufficient time for licensees to respond with the information requested, including any Start Printed Page 46474need to develop this information through supporting engineering calculation or analyses?

b. If a current or projected cumulative effect poses a significant challenge, what should be done to address it? For example, if more time is required to develop and provide the information, what period of time is sufficient? Are there equally effective alternatives to providing the requested information to the NRC that reduce the cumulative effects?

c. Do other (NRC or other regulatory agency) regulatory actions (e.g., Orders, rules, generic letter, bulletins, 50.54(f) requests) influence licensee responses to this draft generic letter? If so what are they and do you have a suggested approach to reduce the cumulative effects in light of these other regulatory actions?

d. Are there other projects that licensees are undertaking, plan to undertake, or should be undertaking that provide greater safety benefit, that might be displaced or delayed as a result of the expenditure of effort and resources to respond to this generic letter?

e. Are there unintended consequences associated with responding to this generic letter at this time?

f. Please comment on the NRC's supporting justification for this generic letter.

IV. Public Meeting

The NRC is requesting public comments on the draft generic letter. The NRC plans to hold a public meeting approximately 45 days into the comment period to discuss draft Generic Letter 2013 XX-XX: “Treatment of Natural Phenomena Hazards In Fuel Cycle Facilities” (ADAMS Accession No. ML13157A158), to engage industry stakeholders and members of the public in a discussion of this issue. This meeting is scheduled during the comment period to allow industry stakeholders and members of the public time to submit comments on the proposed generic communication before the comment period closes. All comments that are to receive consideration in the final generic letter must still be submitted electronically or in writing as indicated in the ADDRESSES section of this document.

Additional details regarding the meeting will be posted at least 10 days prior to the public meeting on the NRC's Public Meeting Schedule Web site at​public-involve/​public-meetings/​index.cfm. Information regarding topics to be discussed, changes to the agenda, whether the meeting has been cancelled or rescheduled, and the time allotted for public comments can be obtained from the Public Meeting Schedule Web site.
