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.
Very truly yours,

Dear Class3 Error Recipient:
Attached to this letter you will find ANSYS Class3 Error Reports
95-48, 95-49, 95-50 and 95-51.
I would like to take this opportunity to extend my greetings to you
as the new Quality Assurance Manager, I am also pleased to inform you
that Prashant Ambe, my predecessor, has been appointed Revision Manager
for ANSYS Revision 5.3.
Let me assure you that I will continue to maintain the high quality
of the Class3 error notification system that you have seen in the past.
Also, I would be glad to address any questions you have about the quality
assurance procedures at ANSYS, Inc.
Sincerely,
ANSYS, Inc.

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. A.n 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
pan 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) listed below,
ANSYS/ED contains all errors shown for the full ANSYS product,
starting at Rev.
5.0, and beyond, unless
otherwise noted.
PC/LINEAR is equivalent to WS/LINEAR at Rev. 4.4A,
and ANSYS/LINEAR 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 errors
shown for the full ANSYS product,
for included pre-
and postprocessing
functionality
ANSYS [Registered Trademark] CLASS3 ERROR REPORT
ERROR NO: 95-48
KEYWORDS: APDL ARNODE GET FUNCTION
DESCRIPTION OF ERROR:
The ARNODE (N) "get function" returns an incorrect value for the
contributing area at node N for all 2-D planar solids (with or without
midside nodes), axisymmetric solids (with or without midside nodes), and
3-D volumetric solids (with midside nodes only).
Also, it returns a zero value as a contributing area at node N for
elements (SOLID5, PLANE13, FLUID29, FLUID30, PLANE53, SOLID62, SOLID96,
SOLID97, SOLID98, PLANE121, SOLID122, SOLID123, INFIN110 and INFIN111)
which have neither pressure nor convection surfaces.
FIRST INCORRECT VERSION (S):*_/ CORRECTED IN:*_/
Rev. 5.1 Rev. 5.2
ANSYS/FLOTRAN Rev. 5.1 ANSYS/FLOTRAN Rev. 5.2
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
While using only 3-D volumetric solid without midside node,
temporarily switch the element type to SOLID45 for the ARNODE operation,
then switch the element type back to the original type.

the full ANSYS program is implied. For products not listed, this error
does not apply, but see the reverse side for equivalent product
designations.
Unless noted otherwise, this error report also applies to all revisions
after the first incorrect one and prior to the corrected revision. All
revisions after "corrected in" are corrected. Manual corrections are

ERROR NO: 95-49
KEYWORDS: FLOTRAN ELEM141 ELEM142
DESCRIPTION OF ERROR:
FLOTRAN models with triangular FLUID141 elements or tetrahedral
FLUID142 elements which use the transient, compressible flow algorithm
yield time-inaccurate velocity and pressure solutions if the flow is
supersonic.
FIRST INCORRECT VERSION(S): *_/ CORRECTED IN:*_/
Rev. 5.1 Rev. 5.3
ANSYS/FLOTRAN Rev. 5.1 ANSYS/FLOTRAN Rev. 5.3
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
Use quadrilateral FLUID141 on hexahedral FLUID142 elements instead.

ERROR NO: 95-51
KEYWORDS: APDL *_/VOPER GATHER
DESCRIPTION OF ERROR:
The gathering operator (GATH) works incorrectly for the *_/VOPER command
if the dimension (*_/DIM command) of the result vector (ParR) is less
than the dimension of the first operand vector (Par1).
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Rev. 5.1 Rev. 5.2
ANSYS/FLOTRAN Rev. 5.1 ANSYS/FLOTRAN Rev. 5.2
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
On the *_/DIM command, dimension the vector ParR to have the same
length as Par1, regardless of the length of Par2. Extra zero values in
the resultant vector ParR should then be ignored.
