Box 3707 Seattle, WA 98124-2207 BOEING August 1, 1995 G-1151-SJA-95-284 Document Control Desk United States Nuclear Regulatory Commission Washington, D.C. 20555 Reference: a) Boeing Letter G-1151-RSO-92-365 dated August 31, 1992; R. S. Orr to the NRC Operations Center b) NRC Letter Docket No. 99901227 dated August 12, 1992; L. J. Norrholm to R. S. 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, Sandra J. Andrews Nuclear Administrator G-1151 M/S 7A-33 (206) 865-6248 Attachment(s): ANSYS Class3 Error Reports 95-44, 95-45, 95-46 and 95-47 ANSYS (Registered Trademark) ANSYS, Inc. 201 Johnson Road Telephone 412.746.3304 Houston, PA 15342-1300 Facsimile 412.746.9494 July 25, 1995 Dear Class3 Error Recipient: Enclosed you will find ANSYS Class3 Error Reports 95-44, 95-45, 95-46 and 95-47. 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 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 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: 95-44 KEYWORDS: DOCU APDL CENTRX/Y/Z ELEMENT CENTROID DESCRIPTION OF ERROR: The get functions CENTRX(n), CENTRY(n), and CENTRZ(n) always return the element centroid location in the global Cartesian system, but the documentation in the Commands Manual implies that the location returned is in the active coordinate system (CSYS). FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.1 Commands Manual Rev. 5.2 Commands Manual SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: COMMENTS: The corresponding *GET command (*GET,Par,ELEM,n,CENT,X/Y/Z) does return the centroid location in the active coordinate system. AUTHOR/CORRECTOR: DATE: July 24, 1995 Krishna Raichur REVIEWED BY QA: DATE: July 24, 1995 Prashant Ambe APPROVAL: DATE: July 24, 1995 John A. Swanson *_/ If a product name is not included in the "first incorrect version", 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 included in on-line documentation as appropriate. Please see the reverse side of this sheet for additional information on ANSYS revision identifiers. FORM SASI-QA25 DEC 19, 1988 ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-45 KEYWORDS: PREP7 SOLID MODEL ASUM VSUM DESCRIPTION OF ERROR: ASUM of a sector of a "hollow" circular area and VSUM of a sector of hollow cylindrical or spherical volumes with inner to outer radius ratio of greater than .95 will calculate inaccurate areas/volumes. As the ratio of inner to outer radius increases toward 1, the results will deteriorate significantly.

FORM SASI-QA25 DEC 19, 1988 ANSYS (Registered Trademark) CLASS3 ERROR REPORT ERROR NO: 95-46 KEYWORDS: PSTRES SSTIF GUI DESCRIPTION OF ERROR: The PSTRES and SSTIF commands are functionally similar and if they are used together only the last command is active. When using the Analysis Options dialog box in the Graphical User Interface (GUI), the SSTIF command has no effect because the PSTRES command is executed subsequently, therefore turning off any effects of the SSTIF command. The menu path is: Solution (right arrow) Analysis Options. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.0 Commands Manual Rev. 5.2 Commands Manual Rev. 5.0 Procedures Manual Rev. 5.2 Procedures Manual Rev. 5.1 (GUI) Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Use either the PSTRES command or SSTIF command. but not both. This requires entering the SSTIF or PSTRES command after executing the Analysis Options dialog box in the GUI.
