NON-RESTART JUSTIFICATION-

SUMMARY

SU8 CATEGORY / ELEMENT 2b5.3(B)

The issues identified in this element refer to possible programmatic deficiencies having to do with the retention and-storage of design calculations. The issues are documentation and records related.

~

~

The documentation and records requirements stipulated by 10CFR50 Appendix B, and ANSI N45.2.9, are reflected in the appropriate engineering' procedures. These procedures were reviewed and in general

  • they adequately address quality record requirements and indicate management awareness and commitments to these requirements.

.c Issues concerning the existence, quality and scope of design calculations

'were addressed in Sequoyah Element Reports 205.1 and 205.2 as restart issues. The programmatic deficiencies identified in those report findings are being addressed prior to restart.

. ('C')::,

The storage and retention of design calculations as quality records, while an essential part of the plant quality program, do-not impact the performance or the quality of constructed systems. Concerns which address the technical adequacy of design calculations are addressed in other Sequoyah Element Reports as restart issues (e.g., 220.3, Design of Supports). Consequently, the programmatic issues in this element would not, of themselves, have an impact on plant safety.

. Design calculation issues requiring resolution prior to restart are i addressed accordingly in the above noted Sequoyah Element Reports.

Future problems in this area can be prevented through conformance to

~

existing procedures and practices covering the retention and storage of design calculations, assisted by Engineering Assurance surveillance.
