SUPPLEMENTARY INFORMATION:

I. Obtaining Information and Submitting Comments

A. Obtaining Information

    Please refer to Docket ID NRC-2014-0206 when contacting the NRC 
about the availability of information regarding this document. You may 
obtain publicly-available information related to this action by the 
following methods:
     Federal eRulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2014-0206.

ADAMS accession number for each document referenced (if it is available 
in ADAMS) is provided the first time that a document is referenced. 
Draft NUREG-1824 (EPRI 3002002182), ``Verification and Validation of 
Selected Fire Models for Nuclear Power Plant Applications, Supplement 
1'' is available in ADAMS under Accession No. ML14338A237.
     NRC's PDR: You may examine and purchase copies of public 
documents at the NRC's PDR, Room O1-F21, One White Flint North, 11555

B. Submitting Comments

    Please include Docket ID NRC-2014-0206 in the subject line of your 
comment submission, in order to ensure that the NRC is able to make 
your comment submission available to the public in this docket.
    The NRC cautions you not to include identifying or contact 
information that you do not want to be publicly disclosed in your 
comment submission. The NRC posts all comment submissions at http://www.regulations.gov as well as entering the comment submissions into 
ADAMS. The NRC does not routinely edit comment submissions to remove 
identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that they do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment submissions into ADAMS.

II. Further Information

    In 2007, the NRC's Office of Nuclear Regulatory Research and the 
Electric Power Research Institute (EPRI) under a joint Memorandum of 
Understanding, together with the National Institute of Standards and 
Technology, conducted a research project to verify and validate five 
fire models that have been used for nuclear power plant applications. 
The results of that effort were documented in a seven-volume report, 
NUREG-1824 (EPRI 1011999), Verification & Validation of Selected Fire 
Models for Nuclear Power Plant Applications. Technical review of fire 
models is necessary to ensure that analysts can judge the adequacy of 
the scientific and technical basis for the models, select models 
appropriate for a desired use, and understand the levels of confidence 
that can be placed in the results predicted by the models. The work was 
performed using state of the art fire dynamics calculation methods/
models and the most applicable fire test data. The NUREG-1824 (EPRI 
3002002182), Verification & Validation of Selected Fire Models for 
Nuclear Power Plant Applications, Supplement 1, expands on the previous 
verification and validation effort and evaluates the latest versions of 
the five fire models including additional test data for validation of 
the models. As with the previous effort, the results are reported in 
the form of ranges of accuracies for the fire model predictions and, 
the project was performed in accordance with the guidelines that the 
American Society for Testing and Materials (ASTM) set forth in ASTM E 
1355-12, Standard Guide for Evaluating the Predictive Capability of 
Deterministic Fire Models (2012).
