---------------------------------------------------------------------------

II

    On March 11, 2011, a magnitude 9.0 earthquake struck off the coast 
of the Japanese island of Honshu. The earthquake resulted in a large 
tsunami, estimated to have exceeded 14 meters (45 feet) in height, that 
inundated the Fukushima Dai-ichi nuclear power plant site. The 
earthquake and tsunami produced widespread devastation across 
northeastern Japan and significantly affected the infrastructure and 
industry in the northeastern coastal areas of Japan.
    When the earthquake occurred, Fukushima Dai-ichi Units 1, 2, and 3 
were in operation and Units 4, 5, and 6 were shut down for routine 
refueling and maintenance activities. The Unit 4 reactor fuel was 
offloaded to the Unit 4 spent fuel pool (SFP). Following the 
earthquake, the three operating units automatically shut down and 
offsite power was lost to the entire facility. The emergency diesel 
generators (EDGs) started at all six units providing alternating 
current (ac) electrical power to critical systems at each unit. The 
facility response to the earthquake appears to have been normal.
    Approximately 40 minutes following the earthquake and shutdown of 
the operating units, the first large tsunami wave inundated the site, 
followed by additional waves. The tsunami caused extensive damage to 
site facilities and resulted in a complete loss of all ac electrical 
power at Units 1 through 5, a condition known as station blackout. In 
addition, all direct current electrical power was lost early in the 
event on Units 1 and 2 and after some period of time at the other 
units. Unit 6 retained the function of one air-cooled EDG. Despite 
their actions, the operators lost the ability to cool the fuel in the 
Unit 1 reactor after several hours, in the Unit 2 reactor after about 
70 hours, and in the Unit 3 reactor after about 36 hours, resulting in 
damage to the nuclear fuel shortly after the loss of cooling 
capabilities.
    Following the events at the Fukushima Dai-ichi nuclear power plant, 
the NRC established a senior-level agency task force referred to as the 
Near-Term Task Force (NTTF). The NTTF was tasked with conducting a 
systematic and methodical review of the NRC regulations and processes 
and determining if the agency should make additional improvements to 
these programs in light of the events at Fukushima Dai-ichi. As a 
result of this review, the NTTF developed a comprehensive set of 
recommendations, documented in SECY-11-0093, ``Near-Term Report and 
Recommendations for Agency Actions Following the Events in Japan,'' 
dated July 12, 2011. These recommendations were enhanced by the NRC 
staff following interactions with stakeholders. Documentation of the 
staff's efforts is contained in SECY-11-0124, ``Recommended Actions to 
be Taken Without Delay From the Near-Term Task Force Report,'' dated 
September 9, 2011, and SECY-11-0137, ``Prioritization of Recommended 
Actions to be Taken in Response to Fukushima Lessons Learned,'' dated 
October 3, 2011.
    As directed by the Commission's staff requirements memorandum (SRM) 
for SECY-11-0093, the NRC staff reviewed the NTTF recommendations 
within the context of the NRC's existing regulatory framework and 
considered the various regulatory vehicles available to the NRC to 
implement the recommendations. SECY-11-0124 and SECY-11-0137 
established the staff's prioritization of the recommendations based 
upon the potential safety enhancements.
    Since receiving the Commission's direction in SRM-SECY-11-0124 and 
SRM-SECY-11-0137, the NRC staff conducted public meetings to discuss 
enhanced mitigation strategies intended to maintain or restore core 
cooling, containment, and SFP cooling capabilities following beyond-
design-basis external events. At these meetings, the industry described 
its proposal for a Diverse and Flexible Mitigation Capability (FLEX), 
as documented in the Nuclear Energy Institute's (NEI's) letter dated 
December 16, 2011 (Agency Documents Access and Management System 
(ADAMS) Accession No. ML11353A008). FLEX is proposed as a strategy to 
fulfill the key safety functions of core cooling, containment 
integrity, and spent fuel cooling. Stakeholder input influenced the 
staff to pursue a more performance-based approach to improve the safety 
of operating power reactors than envisioned in NTTF Recommendation 4.2, 
SECY-11-0124, and SECY-11-0137.
    Current regulatory requirements and existing plant capabilities 
allow the NRC to conclude that a sequence of events such as the 
Fukushima Dai-ichi accident is unlikely to occur in the U.S. Therefore, 
continued operation and continued licensing activities do not pose an 
imminent threat to public health and safety. However, NRC's assessment 
of new insights from the events at Fukushima Dai-ichi leads the staff 
to conclude that additional requirements must be imposed on Licensees 
or CP holders to increase the

[[Page 16092]]

capability of nuclear power plants to mitigate beyond-design-basis 
external events. These additional requirements are needed to provide 
adequate protection to public health and safety, as set forth in 
Section III of this Order.
    Guidance and strategies required by this Order would be available 
if the loss of power, motive force, and normal access to the ultimate 
heat sink to prevent fuel damage in the reactor and SFP, affected all 
units at a site simultaneously. This Order requires a three-phase 
approach for mitigating beyond-design-basis external events. The 
initial phase requires the use of installed equipment and resources to 
maintain or restore core cooling, containment, and SFP cooling. The 
transition phase requires providing sufficient, portable, onsite 
equipment and consumables to maintain or restore these functions until 
they can be accomplished with resources brought from off site. The 
final phase requires obtaining sufficient offsite resources to sustain 
those functions indefinitely.
    Additional details on an acceptable approach for complying with 
this Order will be contained in final Interim Staff Guidance (ISG) 
scheduled to be issued by the NRC in August 2012. This guidance will 
also include a template to be used for the plan that will be submitted 
in accordance with Section IV, Condition C.1 below.

III

    Reasonable assurance of adequate protection of the public health 
and safety and assurance of the common defense and security are the 
fundamental NRC regulatory objectives. Compliance with NRC requirements 
plays a critical role in giving the NRC confidence that Licensees or CP 
holders are maintaining an adequate level of public health and safety 
and common defense and security. While compliance with NRC requirements 
presumptively assures adequate protection, new information may reveal 
that additional requirements are warranted. In such situations, the 
Commission may act in accordance with its statutory authority under 
Section 161 of the Atomic Energy Act of 1954, as amended, to require 
Licensees or CP holders to take action in order to protect health and 
safety and common defense and security.
    To protect public health and safety from the inadvertent release of 
radioactive materials, the NRC's defense-in-depth strategy includes 
multiple layers of protection: (1) Prevention of accidents by virtue of 
the design, construction, and operation of the plant; (2) mitigation 
features to prevent radioactive releases should an accident occur; and 
(3) emergency preparedness programs that include measures such as 
sheltering and evacuation. The defense-in-depth strategy also provides 
for multiple physical barriers to contain the radioactive materials in 
the event of an accident. The barriers are the fuel cladding, the 
reactor coolant pressure boundary, and the containment. These defense-
in-depth features are embodied in the existing regulatory requirements 
and thereby provide adequate protection of the public health and 
safety.
    Following the events of September 11, 2001, the NRC issued Order 
EA-02-026, dated February 25, 2002, which required Licensees to develop 
mitigating strategies related to the key safety functions of core 
cooling, containment, and SFP cooling. NEI Document 06-12, ``B.5.b 
Phase 2 & 3 Submittal Guideline'' (ADAMS Accession No. ML070090060) 
provides guidelines that describe the necessary mitigating strategies. 
The NRC endorsed these guidelines in a letter dated December 22, 2006, 
designated as Official Use Only. Those mitigating strategies were 
developed in the context of a localized event that was envisioned to 
challenge portions of a single unit. The events at Fukushima, however, 
demonstrate that beyond-design-basis external events may adversely 
affect: (1) More than one unit at a site with two or more units, and 
(2) multiple safety functions at each of several units located on the 
same site.
    The events at Fukushima further highlight the possibility that 
extreme natural phenomena could challenge the prevention, mitigation, 
and emergency preparedness defense-in-depth layers. To address the 
uncertainties associated with beyond-design-basis external events, the 
NRC is requiring additional defense-in-depth measures at licensed 
nuclear power reactors so that the NRC can continue to have reasonable 
assurance of adequate protection of public health and safety in 
mitigating the consequences of a beyond-design-basis external event.
    The strategies and guidance developed and implemented by Licensees 
or CP holders in response to the requirements imposed by this Order 
will provide the necessary capabilities to supplement those of the 
permanently installed plant structures, systems, and components that 
could become unavailable following beyond-design-basis external events. 
These strategies and guidance will enhance the safety and preparedness 
capabilities established following September 11, 2001, and codified as 
10 CFR 50.54(hh)(2). In order to address the potential for more 
widespread effects of beyond design basis external events, this Order 
requires strategies with increased capacity to implement protective 
actions concurrently at multiple units at a site. The strategies shall 
be developed to add multiple ways to maintain or restore core cooling, 
containment and SFP cooling capabilities in order to improve the 
defense-in-depth of licensed nuclear power reactors.
    The Commission has determined that ensuring adequate protection of 
public health and safety requires that power reactor Licensees and CP 
holders develop, implement and maintain guidance and strategies to 
restore or maintain core cooling, containment, and SFP cooling 
capabilities in the event of a beyond-design-basis external event. 
These new requirements provide a greater mitigation capability 
consistent with the overall defense-in-depth philosophy, and, 
therefore, greater assurance that the challenges posed by beyond-
design-basis external events to power reactors do not pose an undue 
risk to public health and safety. In order to provide reasonable 
assurance of adequate protection of public health and safety, all 
operating reactor licenses and CPs under Part 50 identified in 
Attachment 1 to this Order shall be modified to include the 
requirements identified in Attachment 2 to this Order. All combined 
licenses (COLs) under 10 CFR part 52 identified in Attachment 1 to this 
Order shall be modified to include the requirements identified in 
Attachment 3 to this Order.
    Accordingly, the NRC has concluded that these measures are 
necessary to ensure adequate protection of public health and safety 
under the provisions of the backfit rule, 10 CFR 50.109(a)(4)(ii), and 
is requiring Licensee or CP holder action. In addition, pursuant to 10 
CFR 2.202, the NRC finds that the public health, safety and interest 
require that this Order be made immediately effective.

IV

    Accordingly, pursuant to Sections 161b, 161i, 161o, and 182 of the 
Atomic Energy Act of 1954, as amended, and the Commission's regulations 
in 10 CFR 2.202, and 10 CFR Parts 50 and 52, it is hereby ordered, 
effective immediately, that all licenses and construction permits 
identified in attachment 1 to this order are modified as follows:
    A. 1. All holders of CPs issued under Part 50 shall, 
notwithstanding the provisions of any Commission regulation or CPs to 
the contrary, comply with the requirements described in Attachment 2 to 
this Order except to the extent that a more stringent

[[Page 16093]]

requirement is set forth in the CP. These CP holders shall complete 
full implementation prior to issuance of an operating license.
    2. All holders of operating licenses issued under Part 50 shall, 
notwithstanding the provisions of any Commission regulation or license 
to the contrary, comply with the requirements described in Attachment 2 
to this Order except to the extent that a more stringent requirement is 
set forth in the license. These Licensees shall promptly start 
implementation of the requirements in Attachment 2 to the Order and 
shall complete full implementation no later than two (2) refueling 
cycles after submittal of the overall integrated plan, as required in 
Condition C.1.a, or December 31, 2016, whichever comes first.
    3. All holders of COLs issued under Part 52 shall, notwithstanding 
the provisions of any Commission regulation or license to the contrary, 
comply with the requirements described in Attachment 3 to this Order 
except to the extent that a more stringent requirement is set forth in 
the license. These Licensees shall promptly start implementation of the 
requirements in Attachment 3 to the Order and shall complete full 
implementation prior to initial fuel load.
    B.1. All Licensees and CP holders shall, within twenty (20) days of 
the date of this Order, notify the Commission, (1) if they are unable 
to comply with any of the requirements described in Attachment 2 or 
Attachment 3, (2) if compliance with any of the requirements is 
unnecessary in their specific circumstances, or (3) if implementation 
of any of the requirements would cause the Licensee or CP holder to be 
in violation of the provisions of any Commission regulation or the 
facility license. The notification shall provide the Licensee's or CP 
holder's justification for seeking relief from or variation of any 
specific requirement.
    2. Any Licensee or CP holder that considers that implementation of 
any of the requirements described in Attachment 2 or Attachment 3 to 
this Order would adversely impact safe and secure operation of the 
facility must notify the Commission, within twenty (20) days of this 
Order, of the adverse safety impact, the basis for its determination 
that the requirement has an adverse safety impact, and either a 
proposal for achieving the same objectives specified in Attachment 2 or 
Attachment 3 requirement in question, or a schedule for modifying the 
facility to address the adverse safety condition. If neither approach 
is appropriate, the Licensee or CP holder must supplement its response 
to Condition B.1 of this Order to identify the condition as a 
requirement with which it cannot comply, with attendant justifications 
as required in Condition B.1.
    C.1. a. All holders of operating licenses issued under Part 50 
shall by February 28, 2013, submit to the Commission for review an 
overall integrated plan including a description of how compliance with 
the requirements described in Attachment 2 will be achieved.
    b. All holders of CPs issued under Part 50 or COLs issued under 
Part 52 shall, within one (1) year after issuance of the final ISG, 
submit to the Commission for review an overall integrated plan 
including a description of how compliance with the requirements 
described in Attachment 2 or Attachment 3 will be achieved.
    2. All Licensees and holders of CPs shall provide an initial status 
report sixty (60) days following issuance of the final ISG and at six 
(6)-month intervals following submittal of the overall integrated plan, 
as required in Condition C.1, which delineates progress made in 
implementing the requirements of this Order.
    3. All Licensees and CP holders shall report to the Commission when 
full compliance with the requirements described in Attachment 2 or 
Attachment 3 is achieved.
    Licensee or CP holders responses to Conditions B.1, B.2, C.1, C.2, 
and C.3, above shall be submitted in accordance with 10 CFR 50.4 and 10 
CFR 52.3, as applicable.
    As applicable, the Director, Office of Nuclear Reactor Regulation 
or the Director, Office of New Reactors may, in writing, relax or 
rescind any of the above conditions upon demonstration by the Licensee 
or CP holder of good cause.

V

    In accordance with 10 CFR 2.202, the Licensee or CP holder must, 
and any other person adversely affected by this Order may, submit an 
answer to this Order, and may request a hearing on this Order, within 
20 days of the date of this Order. Where good cause is shown, 
consideration will be given to extending the time to answer or to 
request a hearing. A request for extension of time in which to submit 
an answer or request a hearing must be made in writing to the Director, 
Office of Nuclear Reactor Regulation or to the Director, Office of New 
Reactors, U.S. Nuclear Regulatory Commission, Washington, DC 20555, and 
include a statement of good cause for the extension. The answer may 
consent to this Order.
    If a hearing is requested by a Licensee, CP holder or a person 
whose interest is adversely affected, the Commission will issue an 
Order designating the time and place of any hearings. If a hearing is 
held, the issue to be considered at such hearing shall be whether this 
Order should be sustained. Pursuant to 10 CFR 2.202(c)(2)(i), the 
licensee, CP holder or any other person adversely affected by this 
Order, may, in addition to demanding a hearing, at the time the answer 
is filed or sooner, move the presiding officer to set aside the 
immediate effectiveness of the Order on the ground that the Order, 
including the need for immediate effectiveness, is not based on 
adequate evidence but on mere suspicion, unfounded allegations, or 
error.
    All documents filed in NRC adjudicatory proceedings, including a 
request for hearing, a petition for leave to intervene, any motion or 
other document filed in the proceeding prior to the submission of a 
request for hearing or petition to intervene, and documents filed by 
interested governmental entities participating under 10 CFR 2.315(c), 
must be filed in accordance with the NRC E-Filing rule (72 FR 49139, 
August 28, 2007). The E-Filing process requires participants to submit 
and serve all adjudicatory documents over the internet, or in some 
cases to mail copies on electronic storage media. Participants may not 
submit paper copies of their filings unless they seek an exemption in 
accordance with the procedures described below.
    To comply with the procedural requirements of E-Filing, at least 10 
days prior to the filing deadline, the participant should contact the 
Office of the Secretary by email at <a href="/cdn-cgi/l/email-protection#bfd7dadecdd6d1d891dbd0dcd4dacbffd1cddc91d8d0c9"><span class="__cf_email__" data-cfemail="442c2125362d2a236a202b272f2130042a36276a232b32">[email protected]</span></a>, or by 
telephone at (301) 415-1677, to request (1) a digital ID certificate, 
which allows the participant (or its counsel or representative) to 
digitally sign documents and access the E-Submittal server for any 
proceeding in which it is participating; and (2) advise the Secretary 
that the participant will be submitting a request or petition for 
hearing (even in instances in which the participant, or its counsel or 
representative, already holds an NRC-issued digital ID certificate). 
Based upon this information, the Secretary will establish an electronic 
docket for the hearing in this proceeding if the Secretary has not 
already established an electronic docket.
    Information about applying for a digital ID certificate is 
available on

[[Page 16094]]

NRC's public Web site at http://www.nrc.gov/site-help/e-submittals/apply-certificates.html. System requirements for accessing the E-
Submittal server are detailed in NRC's ``Guidance for Electronic 
Submission,'' which is available on the agency's public Web site at 
http://www.nrc.gov/site-help/e-submittals.html. Participants may 
attempt to use other software not listed on the web site, but should 
note that the NRC's E-Filing system does not support unlisted software, 
and the NRC Meta System Help Desk will not be able to offer assistance 
in using unlisted software.
    If a participant is electronically submitting a document to the NRC 
in accordance with the E-Filing rule, the participant must file the 
document using the NRC's online, web-based submission form. In order to 
serve documents through the Electronic Information Exchange, users will 
be required to install a web browser plug-in from the NRC web site. 
Further information on the web-based submission form, including the 
installation of the Web browser plug-in, is available on the NRC's 
public Web site at http://www.nrc.gov/site-help/e-submittals.html.
    Once a participant has obtained a digital ID certificate and a 
docket has been created, the participant can then submit a request for 
hearing or petition for leave to intervene. Submissions should be in 
Portable Document Format (PDF) in accordance with NRC guidance 
available on the NRC public Web site at http://www.nrc.gov/site-help/e-submittals.html. A filing is considered complete at the time the 
documents are submitted through the NRC's E-Filing system. To be 
timely, an electronic filing must be submitted to the E-Filing system 
no later than 11:59 p.m. Eastern Time on the due date. Upon receipt of 
a transmission, the E-Filing system time-stamps the document and sends 
the submitter an email notice confirming receipt of the document. The 
E-Filing system also distributes an email notice that provides access 
to the document to the NRC Office of the General Counsel and any others 
who have advised the Office of the Secretary that they wish to 
participate in the proceeding, so that the filer need not serve the 
documents on those participants separately. Therefore, applicants and 
other participants (or their counsel or representative) must apply for 
and receive a digital ID certificate before a hearing request/petition 
to intervene is filed so that they can obtain access to the document 
via the E-Filing system.
    A person filing electronically using the agency's adjudicatory E-
Filing system may seek assistance by contacting the NRC Meta System 
Help Desk through the ``Contact Us'' link located on the NRC Web site 
at http://www.nrc.gov/site-help/e-submittals.html, by email at 
<a href="/cdn-cgi/l/email-protection#a0edf3e8e48ef2c5d3cfd5d2c3c5e0ced2c38ec7cfd6"><span class="__cf_email__" data-cfemail="9fd2ccd7dbb1cdfaecf0eaedfcfadff1edfcb1f8f0e9">[email protected]</span></a>, or by a toll-free call at (866) 672-7640. The 
NRC Meta System Help Desk is available between 8 a.m. and 8 p.m., 
Eastern Time, Monday through Friday, excluding government holidays.
    Participants who believe that they have a good cause for not 
submitting documents electronically must file an exemption request, in 
accordance with 10 CFR 2.302(g), with their initial paper filing 
requesting authorization to continue to submit documents in paper 
format. Such filings must be submitted by: (1) First class mail 
addressed to the Office of the Secretary of the Commission, U.S. 
Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention: 
Rulemaking and Adjudications Staff; or (2) courier, express mail, or 
expedited delivery service to the Office of the Secretary, Sixteenth 
Floor, One White Flint North, 11555 Rockville Pike, Rockville, 
Maryland, 20852, Attention: Rulemaking and Adjudications Staff. 
Participants filing a document in this manner are responsible for 
serving the document on all other participants. Filing is considered 
complete by first-class mail as of the time of deposit in the mail, or 
by courier, express mail, or expedited delivery service upon depositing 
the document with the provider of the service. A presiding officer, 
having granted an exemption request from using E-Filing, may require a 
participant or party to use E-Filing if the presiding officer 
subsequently determines that the reason for granting the exemption from 
use of E-Filing no longer exists.
    Documents submitted in adjudicatory proceedings will appear in 
NRC's electronic hearing docket, which is available to the public at 
http://ehd1.nrc.gov/ehd/, unless excluded pursuant to an order of the 
Commission, or the presiding officer. Participants are requested not to 
include personal privacy information, such as social security numbers, 
home addresses, or home phone numbers in their filings, unless an NRC 
regulation or other law requires submission of such information. With 
respect to copyrighted works, except for limited excerpts that serve 
the purpose of the adjudicatory filings and would constitute a Fair Use 
application, participants are requested not to include copyrighted 
materials in their submission.
    If a person other than the Licensee or CP holder requests a 
hearing, that person shall set forth with particularity the manner in 
which his interest is adversely affected by this Order and shall 
address the criteria set forth in 10 CFR 2.309(d).
    In the absence of any request for hearing, or written approval of 
an extension of time in which to request a hearing, the provisions 
specified in Section IV above shall be final twenty (20) days from the 
date of this Order without further order or proceedings. If an 
extension of time for requesting a hearing has been approved, the 
provisions specified in Section IV shall be final when the extension 
expires if a hearing request has not been received. An answer or a 
request for hearing shall not stay the immediate effectiveness of this 
order.

Requirements for Mitigation Strategies for Beyond-Design-Basis External 
Events at Operating Reactor Sites and Construction Permit Holders

    This Order requires a three-phase approach for mitigating beyond-
design-basis external events. The initial phase requires the use of 
installed equipment and resources to maintain or restore core cooling, 
containment and spent fuel pool (SFP) cooling capabilities. The 
transition phase requires providing sufficient, portable, onsite 
equipment and consumables to maintain or restore these functions until 
they can be accomplished with resources brought from off site. The 
final phase requires obtaining sufficient offsite resources to sustain 
those functions indefinitely.
    (1) Licensees or construction permit (CP) holders shall develop, 
implement, and maintain guidance and strategies to maintain or restore 
core cooling, containment and SFP cooling capabilities following a 
beyond-design-basis external event.
    (2) These strategies must be capable of mitigating a simultaneous 
loss of all alternating current (ac) power and loss of normal access to 
the ultimate heat sink and have adequate capacity to address challenges 
to core cooling, containment, and SFP cooling capabilities at all units 
on a site subject to this Order.
    (3) Licensees or CP holders must provide reasonable protection for 
the associated equipment from external events. Such protection must 
demonstrate that there is adequate capacity to address challenges to 
core cooling, containment, and SFP cooling capabilities at all units on 
a site subject to this Order.
    (4) Licensees or CP holders must be capable of implementing the 
strategies in all modes.
    (5) Full compliance shall include procedures, guidance, training, 
and acquisition, staging, or installing of equipment needed for the 
strategies.

Requirements for Mitigation Strategies for Beyond-Design-Basis External 
Events at Col Holder Reactor Sites (VOGTLE Units 3 and 4)

    Attachment 2 to this order for Part 50 licensees requires a phased 
approach for mitigating beyond-design-basis external events. The 
initial phase requires the use of installed equipment and resources to 
maintain or restore core cooling, containment and spent fuel pool (SFP) 
cooling capabilities. The transition phase requires providing 
sufficient, portable, onsite equipment and consumables to maintain or 
restore these functions until they can be accomplished with resources 
brought from off site. The final phase requires obtaining sufficient 
offsite resources to sustain those functions indefinitely.
    The design bases of Vogtle Units 3 and 4 includes passive design 
features that provide core, containment and SFP cooling capability for 
72 hours, without reliance on alternating current (ac) power. These 
features do not rely on access to any external water sources since the 
containment vessel and the passive containment cooling system serve as 
the safety-related ultimate heat sink. The NRC staff reviewed these 
design features prior to issuance of the combined licenses for these 
facilities and certification of the AP1000 design referenced therein. 
The AP1000 design also includes equipment to maintain required safety 
functions in the long term (beyond 72 hours to 7 days) including 
capability to replenish water supplies. Connections are provided for 
generators and pumping equipment that can be brought to the site to 
back up the installed equipment. The staff concluded in its final 
safety evaluation report for the AP1000 design that the installed 
equipment (and alternatively, the use of transportable equipment) is 
capable of supporting extended operation of the passive safety systems 
to maintain required safety functions in the long term. As such, this 
Order requires Vogtle Units 3 and 4 to address the following 
requirements relative to the final phase.
    (1) Licensees shall develop, implement, and maintain guidance and 
strategies to maintain or restore core cooling, containment and SFP 
cooling capabilities following a beyond-design-basis external event.
    (2) These strategies must be capable of mitigating a simultaneous 
loss of all ac power and loss of normal access to the normal heat sink 
and have adequate capacity to address challenges to core cooling, 
containment, and SFP cooling capabilities at all units on a site 
subject to this Order.
    (3) Licensees must provide reasonable protection for the associated 
equipment from external events. Such protection must demonstrate that 
there is adequate capacity to address challenges to core cooling, 
containment, and SFP cooling capabilities at all units on a site 
subject to this Order.
    (4) Licensees must be capable of implementing the strategies in all 
modes.
    (5) Full compliance shall include procedures, guidance, training, 
and acquisition, staging, or installing of equipment needed for the 
strategies.
