Fire Human Reliability Analysis Guidelines, Draft Report for Comment'' 
was written as a collaborative effort by the NRC's Office of Nuclear 
Regulatory Research (RES) and the Electric Power Research Institute 
(EPRI) to provide guidance on how to perform the human reliability 
analysis (HRA) for a fire probabilistic risk analysis. In 2007, EPRI 
and NRC-RES embarked on a cooperative project to develop explicit 
guidance for estimating human error probabilities for human error 
events under fire generated conditions, building upon existing HRA 
methods. This report describes the methodology and guidance developed 
through this project. This report includes guidance on addressing the 
range of fire procedures used in existing plants, the

range of strategies for main control room abandonment, and the 
potential impact of fire-induced spurious electrical effects on crew 
    Due to the detailed nature of the processes described in this 
report and the level of effort required to provide a quality review, a 
request was submitted to the NRC for an extension of the public comment 
period for NUREG-1921 (EPRI 1019196). NRC-RES reviewed this request and 
has agreed to extend the public comment period an additional 32 days to 
March 19, 2010.

    Dated at Rockville, Maryland, this 26th day of January, 2010.

    For the Nuclear Regulatory Commission.
