SUMMARY: The Nuclear Regulatory Commission has issued for public
comment a document entitled: ``NUREG/CR-7010, Cable Heat Release,
Ignition, and Spread in Tray Installations During Fire (CHRISTIFIRE)
Volume 1: Horizontal Trays, Draft Report for Comment.''
DATES: Please submit comments by November 15, 2010. Comments received
after this date will be considered if it is practical to do so, but the
NRC staff is able to ensure consideration only for comments received on
or before this date.
ADDRESSES: You may submit comments by any one of the following methods.
Please include Docket ID NRC-2010-0316 in the subject line of your
comments. Comments submitted in writing or in electronic form will be
posted on the NRC website and on the Federal rulemaking Web site
Regulations.gov. Because your comments will not be edited to remove any
identifying or contact information, the NRC cautions you against
including any information in your submission that you do not want to be
publicly disclosed.
The NRC requests that any party soliciting or aggregating comments
received from other persons for submission to the NRC inform those
persons that the NRC will not edit their comments to remove any
identifying or contact information, and therefore, they should not
include any information in their comments that they do not want
publicly disclosed.

SUPPLEMENTARY INFORMATION: NUREG/CR-7010, Volume 1 documents the first
phase of a multi-year program called CHRISTIFIRE (Cable Heat Release,
Ignition, and Spread in Tray Installations during FIRE). The overall
goal of the program is to quantify the burning characteristics of
grouped electrical cables. The first phase of the program focuses on
horizontal tray configurations. The experiments conducted range from
micro-scale, in which very small (5 mg) samples of cable materials were
burned in a calorimeter to determine their heat of combustion and other
properties; to full-scale, in which horizontal, ladder-back trays
loaded with varying amounts of cable were burned under a large oxygen-
depletion calorimeter. Other experiments include cone calorimetry,
smoke and effluent characterization in a small test furnace, and
intermediate-scale calorimetry involving a single tray of cables
underneath a bank of radiant panels. The results of the small-scale
experiments are to serve as input data for fire models, while the
results of the full-scale experiments are to serve as validation data
for the models.
Dated at Rockville, Maryland, this 28th day of September 2010.
