Dear Sir or Madam:

In accordance with the reference correspondence and 10 CFR 21, Boeing is
sending the NRC the attached error notice(s) received from our former
software suppliers.  Because of unknown current addresses, the following
former customers were not notified:

     Reactor Controls, Inc.

     Echo Energy Consultants, Inc.

     Nuclear Applications and Systems Analysis Company (Japan)

     Nuclear Power Services

Error notices have been sent to our other former customers.

->   Please note the following changes:

     1.   Sandra J. Andrews has replaced R. S. Orr as Nuclear
          Administrator

     2    Because of organization changes within Boeing, our parent
          division is now Boeing Information & Support Services instead
          of Boeing Computer Services.  Our mailing address will remain
          the same.

Very truly yours,

                  ANSYS Revision Identifier Description

     ANSYS revision identifiers consist of a major revision level, a
minor revision level, a correction level, and occasionally a special
version level.  An example of how this is constructed is shown below:

Figure "5.0A-10" omitted.

     Major revision level changes indicate that new features have been
added to the program and that some level of program architecture change
and/or file structure has occurred.  Minor revision level changes also
indicate that new features have been added to the program, but files are
upwardly compatible.  All known error fixes are included in both minor
and major revisions.  Changes to the correction level indicate that it is
primarily an error correction release.  Special version identifiers
indicate that one or more additional minor changes have been made to the
program, normally to circumvent an error.  Special versions are not
general releases to all ANSYS licensees, since they typically represent
errors occurring only on one system, a subset of our customers who have
specific graphics devices, etc.

     The ANSYS revision identifier(s) shown under "corrected in" on the
front side of this Class3 Error Report indicates the first possible
revision that could contain the correction A major program change needed
to fix an error can dictate that the next minor or major revision will
contain the fix rather than the next correction level.  For example, when
errors were being reported while Rev.4.3A was the latest production
version, most Class3 error reports indicated that 4.3B was the "corrected
in" revision.  Others requiring significant code restructuring were
reported as fixed in 4.4. Rev. 4.3B was never released, but Rev.  4.4
contained all error corrections noted as fixed in 4.3B.

     An identifier indicated under "corrected in" does not guarantee that
a general release of that revision of ANSYS will occur.  It does indicate
that the correction is known and implemented in the coding that would be
part of that general release.

                     Equivalent Product Identifiers

     The ANSYS family of products occasionally undergoes name changes
between revisions and/or changes in the functionality of derived products
(such as ANSYS-PC/LINEAR).  To minimize the potential for confusion in
these areas, the important product name equivalences (similar program
functionality and error content) are listed below.

     ANSYS/ED       contains all errors           the full ANSYS product,
                    shown for                     starting at Rev. 5.0,
                                                  and beyond unless
                                                  otherwise noted.

     PC/LINEAR      is equivalent to              WS/LINEAR at Rev.4.4A.
                                             and  ANSYS starting at
                                                  Rev. 5.0.

     PC/THERMAL     is equivalent to              WS/THERMAL at Rev.4.4A,
                                             and  ANSYS/THERMAL starting
                                                  at Rev. 5.0.

     PREPPOST       contains relevant             the full ANSYS product,

magnetic element types are defined (ET command), the current density
dialog box in the Graphical User Interface (GUI) has an additional JSZ

DESCRIPTION:

     The split solver ASSEMBLE (FOR STATICS/DYNAMICS) command ignores the
presence of elastic member end connections if member loads or
conventional member releases are also present in the model.  Any
subsequent split solver static or dynamic analysis execution will not
reflect the specified elastic member end connections.  The work around is
to use the STIFFNESS ANALYSIS command for static analysis and the DYNAMIC
ANALYSIS command for dynamic analysis instead of the split solver
commands.
