II. Introduction
The NRC is considering issuance of an amendment to Renewed Facility
Operating License No. TR-5, issued to NIST, for operation of the NBSR,
located in Montgomery County, Maryland.
The proposed amendment would revise the NBSR safety analysis report
allowing a change to the method used to analyze the core loading
pattern. The licensee was developing its core loading pattern and only
recently determined that a license amendment would be required prior to
any startup with the proposed core. NIST is otherwise prepared to
resume operations upon any approval by the NRC of its separate restart
request; therefore, a delay in the NRC's acting on the license
amendment request could delay the ability of the NBSR to resume
operations. Accordingly, consistent with paragraph 50.91(a)(6) of title
10 of the Code of Federal Regulations (10 CFR), the NRC finds that
exigent circumstances exist, in that the licensee and the NRC must act
quickly and that time does not permit the NRC to publish a Federal
Register notice allowing 30 days for prior public comment.
Before any issuance of the proposed license amendment, the NRC will
need to make the findings required by the Atomic Energy Act of 1954, as
amended, and NRC's regulations.
Pursuant to 10 CFR 50.91(a)(6) for amendments to be granted under
exigent circumstances, the NRC has made a proposed determination that
the license amendment request involves no significant hazards
consideration. Under the NRC's regulations in 10 CFR 50.92, this means
that operation of the facility in accordance with the proposed
amendment would not (1) involve a significant increase in the
probability or consequences of an accident previously evaluated; or (2)
create the possibility of a new or different kind of accident from any
accident previously evaluated; or (3) involve a significant reduction
in a margin of safety. As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented as follows:
1. Does the proposed change involve a significant increase in the
probability or consequences of an accident previously evaluated?
Response: No.
AFMS [alternative fuel management scheme] loadings deviate from the
core loading scheme as described in the
[[Page 8919]]
FSAR [Final Safety Analysis Report] 4.5.1.1.2 ``Fuel Management
Scheme''. This amendment introduces a new section to the updated FSAR,
``4.5.1.1.3 Alternative Fuel Management Schemes (AFMS)'', which
describes bounding conditions and analysis requirements for any AFMS.
The amendment also introduces an engineering procedure, namely ``NBSR-
0018-DOC-00 NBSR Alternative Core Loading Schemes Analysis Procedure''
which describes the OFMS [original fuel management scheme] and AFMS, a
basis for the analysis, providing limitations to evaluate potential
AFMS, detailed safety review for a demonstration AFMS, along with a
discussion of results and conclusions to be included in subsequent ECNs
[engineering change notice] dealing with similar AFMS core loadings.
The procedure provides a basis to analyze core loading so that none of
the Technical Specifications (TS) are exceeded.
Several accident scenarios and therefore consequences may be
affected by AFMS core loading deviations. Particularly, all accidents
shown in Table 1 are required to be reevaluated for any AFMS core
loading. Other accident scenarios given in the FSAR, including ``Loss
of Primary Coolant'' (a major rupture in the cold leg of the primary
system is assumed, which leads to draining the reactor core), ``Maximum
Hypothetical Accident (MHA)'', ``Experiment Malfunction'' and
``External Event'' are independent of core loading changes and
therefore remain unchanged. Additionally, Natural Circulation Cooling
at Low Power Operation must be analyzed for each AFMS to show
compliance with Technical Specification 2.2. Natural Circulation
Cooling at Low Power Operation is not an accident scenario but an
analysis to show natural circulation at low power operations.
Note that all of the accident scenarios and Natural Circulation
Cooling at Low Power Operation conditions are analyzed using the RELAP5
[Reactor Excursion and Leak Analysis Program] model as described in the
``NBSR-0018-DOC-00 NBSR Alternative Core Loading Schemes Analysis
Procedure''. The misloading accident is the only one that will require
unique power distributions from corresponding MCNP [Monte Carlo N-
Particle] simulations with the misloaded fuel configuration. Some
scenario conditions are updated based on facility changes and available
new information. ``NBSR-0018-DOC-00 Appendix C'' provides descriptions
and modifications for accident scenarios.
Table 1--The Accident Sequences To Be Re-analyzed, and Their References
in the SAR
------------------------------------------------------------------------
Section in the
Accident sequence SAR
------------------------------------------------------------------------
#1....................... Startup Accident............. 13.1.2.2.2.1
#2....................... Maximum Reactivity Insertion 13.2.2
Accident.
#3....................... Loss of Offsite Power........ 13.1.4.1
#4....................... Loss of Offsite Power with 13.1.4.5
Shutdown Pump failure.
#5....................... Seizure of One Primary Pump.. 13.1.4.2
#6....................... Throttling of Coolant Flow to 13.1.4.4
the Outer Plenum.
#7....................... Throttling of Coolant Flow to 13.1.4.3
the Inner Plenum.
#8....................... Misloading of Fuel........... 13.1.5
------------------------------------------------------------------------
Based on detailed analysis provided in the technical report, and
because these AFMS accident scenarios are specifically analyzed for
probability and consequences, there are, by definition, no changes in
the probability of occurrences or the consequences of previously
analyzed accidents.
Therefore, the proposed FSAR amendment allowing analysis of AFMS
does not involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The requested amendment to the facility license involves a SAR
change to describe engineering analysis procedures for any [AFMS]
wherein which the NBSR core is loaded with a different core loading
pattern than as described in the updated FSAR. An AFMS is any core
loading pattern that deviates from the [OFMS] in a manner such that the
number of the specific type of fuel elements, such as fresh, or used is
different than usual and/or their locations in the core are modified.
As there are no other changes besides that of fuel loading, changes in
the core loading pattern do not initiate a different kind of accident.
Therefore, the proposed amendment will not create the possibility
of a new or different kind of accident from any accident previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The requested amendment to the facility license involves a SAR
change to describe engineering analysis procedures for any Alternative
Fuel Management. The requested amendment to the facility license
involves a SAR change to describe engineering analysis procedures for
any [AFMS] wherein which the NBSR core is loaded with a different core
loading pattern than as described in the updated FSAR. An AFMS is any
core loading pattern that deviates from the [OFMS] in a manner such
that the number of the specific type of fuel elements, such as fresh,
or used is different than usual and/or their locations in the core are
modified. The AFMS can be deemed acceptable as long as the proposed
AFMS is analyzed according to the ``NBSR-0018-DOC-00'' and found to be
within the updated FSAR, Technical Specifications limitations and
boundary conditions listed therein. The boundary conditions are based
on the Technical Specifications and updated FSAR requirements. Because
these alternate fuel management schemes are specifically analyzed for a
reduction in margin of safety, there is, by definition, no significant
reduction in margin of safety. The proposed amendment contains no
changes in the Technical Specification or other safety limitations as
described in the updated FSAR.
Therefore, the proposed amendment of the SAR in allowing this
operation does not involve a significant reduction in a margin of
safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
license amendment request involves a no significant hazards
consideration.
The NRC is seeking public comments on this proposed determination
that the license amendment request involves no
[[Page 8920]]
significant hazards consideration. Any comments received within 14 days
after the date of publication of this notice will be considered in
making any final determination.
Normally, the Commission will not issue the amendment until the
expiration of the 14-day notice period. However, if circumstances
change during the notice period, such that failure to act in a timely
way would result, for example, in prevention of resumption of operation
the Commission may issue the license amendment before the expiration of
the 14-day notice period, provided that its final determination is that
the amendment involves no significant hazards consideration. The final
determination will consider all public and State comments received. If
the Commission takes this action, it will publish in the Federal
Register a notice of issuance. The Commission expects that the need to
take this action will occur very infrequently.
III. Opportunity To Request a Hearing and Petition for Leave To
Intervene
Within 60 days after the date of publication of this notice, any
person (petitioner) whose interest may be affected by this action may
file a request for a hearing and petition for leave to intervene
(petition) with respect to the action. Petitions shall be filed in
accordance with the Commission's ``Agency Rules of Practice and
Procedure'' in 10 CFR part 2. Interested persons should consult 10 CFR
2.309. If a petition is filed, the presiding officer will rule on the
petition and, if appropriate, a notice of a hearing will be issued.
Petitions must be filed no later than 60 days from the date of
publication of this notice in accordance with the filing instructions
in the ``Electronic Submissions (E-Filing)'' section of this document.
Petitions and motions for leave to file new or amended contentions that
are filed after the deadline will not be entertained absent a
determination by the presiding officer that the filing demonstrates
good cause by satisfying the three factors in 10 CFR 2.309(c)(1)(i)
through (iii).
If a hearing is requested and the Commission has not made a final
determination on the issue of no significant hazards consideration, the
Commission will make a final determination on the issue of no
significant hazards consideration, which will serve to establish when
the hearing is held. If the final determination is that the amendment
request involves no significant hazards consideration, the Commission
may issue the amendment and make it immediately effective,
notwithstanding the request for a hearing. Any hearing would take place
after issuance of the amendment. If the final determination is that the
amendment request involves a significant hazards consideration, then
any hearing held would take place before the issuance of the amendment
unless the Commission finds an imminent danger to the health or safety
of the public, in which case it will issue an appropriate order or rule
under 10 CFR part 2.
A State, local governmental body, Federally recognized Indian
Tribe, or designated agency thereof, may submit a petition to the
Commission to participate as a party under 10 CFR 2.309(h) no later
than 60 days from the date of publication of this notice.
Alternatively, a State, local governmental body, Federally recognized
Indian Tribe, or agency thereof may participate as a non-party under 10
CFR 2.315(c).
For information about filing a petition and about participation by
a person not a party under 10 CFR 2.315, see ADAMS Accession No.
ML20340A053 (https://adamswebsearch2.nrc.gov/webSearch2/main.jsp?AccessionNumber=ML20340A053) and on the NRC's public website
at https://www.nrc.gov/about-nrc/regulatory/adjudicatory/hearing.html#participate.
IV. Electronic Submissions (E-Filing)
All documents filed in NRC adjudicatory proceedings including
documents filed by an interested State, local governmental body,
Federally recognized Indian Tribe, or designated agency thereof that
requests to participate under 10 CFR 2.315(c), must be filed in
accordance with 10 CFR 2.302. 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,
unless an exemption permitting an alternative filing method, as further
discussed, is granted. Detailed guidance on electronic submissions is
located in the ``Guidance for Electronic Submissions to the NRC''
(ADAMS Accession No. ML13031A056) and on the NRC's public website at
https://www.nrc.gov/site-help/e-submittals.html.
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 [email protected], or by
telephone at 301-415-1677, to (1) request a digital identification (ID)
certificate, which allows the participant (or its counsel or
representative) to digitally sign submissions and access the E-Filing
system for any proceeding in which it is participating; and (2) advise
the Secretary that the participant will be submitting a petition or
other adjudicatory document (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 proceeding if the
Secretary has not already established an electronic docket.
Information about applying for a digital ID certificate is
available on the NRC's public website at https://www.nrc.gov/site-help/e-submittals/getting-started.html. After a digital ID certificate is
obtained and a docket created, the participant must submit adjudicatory
documents in Portable Document Format. Guidance on submissions is
available on the NRC's public website at https://www.nrc.gov/site-help/electronic-sub-ref-mat.html. A filing is considered complete at the
time the document is 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. ET on the due date. Upon receipt of a
transmission, the E-Filing system time-stamps the document and sends
the submitter an email confirming receipt of the document. The E-Filing
system also distributes an email that provides access to the document
to the NRC's 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 document on those
participants separately. Therefore, applicants and other participants
(or their counsel or representative) must apply for and receive a
digital ID certificate before adjudicatory documents are filed to
obtain access to the documents via the E-Filing system.
A person filing electronically using the NRC's adjudicatory E-
Filing system may seek assistance by contacting the NRC's Electronic
Filing Help Desk through the ``Contact Us'' link located on the NRC's
public website at https://www.nrc.gov/site-help/e-submittals.html, by
email to [email protected], or by a toll-free call at 1-866-672-
7640. The NRC Electronic Filing Help Desk is available between 9 a.m.
and 6 p.m., ET, Monday through Friday, except Federal holidays.
Participants who believe that they have good cause for not
submitting documents electronically must file an exemption request, in
accordance with 10 CFR 2.302(g), with their initial paper
[[Page 8921]]
filing stating why there is good cause for not filing electronically
and requesting authorization to continue to submit documents in paper
format. Such filings must be submitted in accordance with 10 CFR
2.302(b)-(d). Participants filing adjudicatory documents in this manner
are responsible for serving their documents on all other participants.
Participants granted an exemption under 10 CFR 2.302(g)(2) must still
meet the electronic formatting requirement in 10 CFR 2.302(g)(1),
unless the participant also seeks and is granted an exemption from 10
CFR 2.302(g)(1).
Documents submitted in adjudicatory proceedings will appear in the
NRC's electronic hearing docket, which is publicly available at https://adams.nrc.gov/ehd, unless excluded pursuant to an order of the
presiding officer. If you do not have an NRC-issued digital ID
certificate as previously described, click ``cancel'' when the link
requests certificates and you will be automatically directed to the
NRC's electronic hearing dockets where you will be able to access any
publicly available documents in a particular hearing docket.
Participants are requested not to include personal privacy information
such as social security numbers, home addresses, or personal 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
should not include copyrighted materials in their submission.
