Orr; Subject: Response to 10 CFR 21 Inquiry 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, R. S. Orr Nuclear Administrator G-1151 M/S 7A-33 (206) 865-6248 Attachment(s): ANSYS Class3 Error Reports 95-21, 95-22, 95-23, 95-24, 95-25, 95-26, 95-27, 95-28, 95-29 ANSYS, Inc. 201 Johnson Road Telephone 412.746.3304 Houston, PA 15342-1300 Facsimile 412.746.9494 May 9, 1995 Dear Class3 Error Recipient: Enclosed you will find ANSYS Class3 Error Reports 95-21, 95-22, 95- 23, 95-24, 95-25, 95-26, 95-27, 95-28 and 95-29. Sincerely, ANSYS, Inc. Prashant Ambe Quality Assurance Manager 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 that it is primarily an error correction release. Special version identifies indicate that one or more additional minor changes have been made to the program, normally to circumvent an error. Special versions we 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 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 reposes indicated that 4.3B was the "corrected in" revision. Others requiring significant code resources 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 the 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 contain 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 the full ANYS product, shown for for included pre- and postprocessing functionality ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-21 KEYWORDS: ELEM17 PIPE17 THERMAL LOAD DESCRIPTION OF ERROR: All results of an analysis containing PIPE17 elements with thermal loads are incorrect. The incorrect thermal load vector for PIPE17 is of the right order of magnitude, but pollutes the entire solution for analyses containing these elements. FIRST INCORRECT VERSION(S): *_/ CORRECTED IN: *_/ Rev. 5.0 Rev. 5.2 ANSYS PC/LinearPlus Rev. 5.0A ANSYS PC/LinearPlus Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Use PIPE16 for each branch.

FORM SASI-QA25 DEC 19, 1988 ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-22 KEYWORDS: GUI REAL CONSTANTS ELEM46 ELEM91 ELEM99 DESCRIPTION OF ERROR: The real constant information for layered elements SOLID46, SHELL91, and SHELL99 is incorrect if the data is entered by means of the Graphical User Interface (GUI) dialog boxes. This only occurs when the number of layers (NL) is greater than eight for SHELL91 and ten for SOLID46 and SHELL99. The RMODIF commands created by additional dialog boxes after the first are not offset correctly and therefore overwrite previous real constant data input in earlier dialog boxes. FIRST INCORRECT VERSION(S): *_/ CORRECTED IN: *_/ Rev. 5.1 Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Input the real constant information through the "ANSYS Input" window using the R and RMODIF commands.

FORM SASI-QA25 DEC 19, 1988 ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-23 KEYWORDS: BFUNIF TUNIF LSSOLVE LSWRITE LSREAD CDWRITE CDREAD DESCRIPTION OF ERROR: If a uniform temperature (TUNIF or BFUNIF,TEMP) is not explicitly specified, the default value is not written to the load step file (LSWRITE) or the file written by the CDWRITE command. If a non-default TUNIF or BFUNIF, TEMP is then specified and is active in the database, that non-default value will be used for load steps read from the load step file (LSREAD or LSSOLVE) or the file read by the CDREAD command, and could erroneously be used in the solution. FIRST INCORRECT VERSION(S): *_/ CORRECTED IN: *_/ Rev. 5.0 Rev. 5.2 Component Products Rev. 5.0A Component Products Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Before issuing LSREAD, LSSOLVE, or CDREAD, set TUNIF to an APDL parameter that is undefined.

FORM SASI-QA25 DEC 19, 1988 ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-26 KEYWORDS: DL DA LINE SYMMETRY AREA SYMMETRY DESCRIPTION OF ERROR: When line or area symmetry or anti-symmetry conditions are transferred to the finite element model as nodal DOF constraints, no node rotation is performed for any node where its existing nodal DOF direction is within 2.6 degrees of the required constraint direction. FIRST INCORRECT VERSION(S): *_/ CORRECTED IN: *_/ Rev. 4.3 Rev. 5.2 Component Products Rev. 4.3 Component Products Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: For a symmetry or anti-symmetry surface having its normal direction within 2.6 degrees of, but not parallel to, a global DOF direction, use nodal symmetry (the DSYM command) rather than line or area symmetry. (Hint: The CSKP command can be used to define an appropriate local coordinate system to be used with DSYM.) COMMENTS: The corrected version will perform a node rotation unless an existing nodal DOF direction is within 0.081 degrees of the required constraint direction.

FORM SASI-QA25 DEC 19, 1988 ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-28 KEYWORDS: BFKDEL NODAL BODY FORCES DESCRIPTION OF ERROR: BFKDEL has the following errors: 1. The documentation of BFKDEL (which deletes keypoint body forces) does not adequately explain the associated deletion of nodal body forces. The statement: "Deletes body force loads (and all corresponding finite element loads) for a specified keypoint and label:" should read: "Deletes body force loads for specified keypoints and labels. Also deletes the corresponding nodal body force loads from the nodes associated with the specified keypoints, and from the nodes associated with the lines, areas, or volumes connected to the specified keypoints." Note that transfer of the keypoint body forces would have applied body forces to this same set of nodes. 2. BFKDEL, KP, ALL fails to delete ANY nodal body forces. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.0 Rev. 5.2 Component Products Rev. 5.0A Component Products Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: For error 1. Be aware that body forces applied to nodes can be deleted by BFKDEL. For error 2. Use BFKDEL,KP,TEMP (or other specific body force label) rather than BFKDEL,KP,ALL.
