NUCLEAR REGULATORY COMMISSION
NUREG/CR-XXXX, ``Approaches for Using Traditional Probabilistic
Risk Assessment Methods for Digital Systems''; Draft Report for Comment
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice of availability for public comment.
-----------------------------------------------------------------------
SUMMARY: The Nuclear Regulatory Commission (NRC) is conducting research
to support development of regulatory guidance for using risk
information related to digital systems in the licensing actions of
nuclear power plants (NPPs). The objective of this research is to
identify and develop methods, analytical tools, and regulatory guidance
to support (1) Using information on the risks of digital systems in NPP
licensing decisions, and (2) including models of digital systems into
NPP probabilistic risk assessments (PRAs).
In support of this research, Brookhaven National Laboratory (BNL)
is working on the use of traditional
[[Page 58339]]
methods to develop and quantitatively assess reliability models of
digital systems. As part of this work, BNL will apply two selected
traditional methods to two benchmark digital systems. The initial tasks
in the BNL project, including preparatory work for developing the
reliability models of the first benchmark system, are addressed in
draft NUREG/CR-XXXX, ``Approaches for Using Traditional Probabilistic
Risk Assessment Methods for Digital Systems.'' This notice announces
the availability of the draft NUREG/CR for public comment.
DATES: Please submit comments on NUREG/CR-XXXX, ``Approaches for Using
Traditional Probabilistic Risk Assessment Methods for Digital
Systems,'' by November 14, 2007. Comments received after this date will
be considered if practical to do so, but the NRC staff is able to
ensure consideration only for those comments received on or before this
date.
ADDRESSES: NUREG/CR-XXXX, ``Approaches for Using Traditional
Probabilistic Risk Assessment Methods for Digital Systems,'' is
available for inspection and copying for a fee at the NRC's Public
Document Room (PDR), Public File Area O-1F21, One White Flint North,
