Dear Mr. Chairman:
In September 2003, the
Department reported interim completion of Commitment 4.2.1.4 in the
Department’s Implementation Plan for Software Quality Assurance (SQA) in response
to Board Recommendation 2002-1. This
commitment required the Department to issue code-specific guidance reports on
the use of safety analysis toolbox codes identifying applicable regimes in
accident analysis, default inputs, and special conditions for use. The September 2003 correspondence also
indicated that the guidance reports may be updated based on the results of
the gap analysis
performed for Commitment 4.2.1.3.
The Department completed
additional code developer and peer reviews to further improve their accuracy
and issued the final gap analysis reports, which I provided to you on May 12, 2004.
The code-specific guidance reports for
the MACCS2, ALOHA, EPICODE, MELCOR, GENII, and CFAST toolbox codes have now been
updated to reflect the final gap analysis conducted for each toolbox code and
are attached.
Now that we have completed these
reports, the Central Registry processes and procedures are being developed in
conjunction with DOE Order 414.1C, Quality Assurance, and DOE Guide 414.1-4, Implementation Guide
for Use with
Supplemental Safety Software Quality Requirements of
DOE Order 414.1. Questions
concerning this commitment may be directed to Chip Lagdon at (301) 903-4218 or
me at (301) 903-8008.
Sincerely,
Frank B. Russo
Deputy Assistant Secretary
