Safety Software Quality Assurance - Central Registry
A significant improvement in the quality assurance of safety
software used at the Department of Energy (DOE)
nuclear facilities was achieved with the
establishment of a list of "toolbox" codes that are
compliant with the DOE
Safety Software Quality Assurance (SSQA)
requirements of DOE O 414.1D, Quality Assurance, and its safety software guidance,
DOE G 414.1-4. The toolbox codes are used by DOE contractors to perform calculations and to
develop data used to establish the safety basis
for DOE facilities and their operation, and to
support the variety of safety analyses and
safety evaluations developed for these
facilities. The following list of toolbox codes comprises the DOE Safety Software Central
Registry.

Prior to inclusion into the Central Registry an evaluation,
sometimes referred to as a gap analysis, of each code was
conducted to identify any "gaps" between the SQA
practices being allowed and DOE's requirements and criteria
for safety software. Code-specific guidance reports are developed
where needed to identify applicable regimes in accident analysis,
default inputs, and special conditions for using the toolbox
codes for DOE applications. These documents as well as general
information are available through the toolbox code links provided
above.
The codes in the Central Registry were mostly developed outside
of DOE (e.g., in the private sector or other Federal agencies).
Access to the toolbox codes or their use is subject to agreements,
conditions and restrictions established by the code owners
or Federal agencies.
The Chief Health, Safety and Security Officer
(HS-1) is responsible for managing the Safety
Software Central Registry. However, the toolbox
code owners are responsible for ensuring that
the codes are maintained in accordance with
established requirements.
Use of the Central Registry toolbox codes is not mandatory. However, using
the codes offers a number of advantages to the DOE and its
contractors. Some of these advantages include: 1) the gap
analysis evaluation performed provides valuable information
on the code regarding application of SQA requirements, 2)
the evaluation extends beyond the DOE safety software quality
assurance criteria to the review of the code's capability
to properly perform safety basis calculations, 3) the DOE
specific guidance documents identify limitations and vulnerabilities
not readily found in other code documentation, and 4) due
to the established pedigree, assessments of the toolbox code
by Field Office and site contractors may be reduced in scope.
